Ultrasound-guided stellate ganglion block benefits the postoperative recovery of patients undergoing laparoscopic colorectal surgery: a single-center, double-blinded, randomized controlled clinical trial.

BACKGROUND: With the increasing prevalence of colorectal cancer (CRC), optimizing perioperative management is of paramount importance. This study investigates the potential of stellate ganglion block (SGB), known for its stress response-mediating effects, in improving postoperative recovery. We postulate that preoperative SGB may enhance the postoperative recovery of patients undergoing laparoscopic CRC surgery. METHODS: We conducted a randomized controlled trial of 57 patients undergoing laparoscopic colorectal cancer surgery at a single center. Patients, aged 18-70 years, were randomly assigned to receive either preoperative SGB or standard care. SGB group patients received 10 mL of 0.2% ropivacaine under ultrasound guidance prior to surgery. Primary outcome was time to flatus, with secondary outcomes encompassing time to defecation, lying in bed time, visual analog scale (VAS) pain score, hospital stays, patient costs, intraoperative and postoperative complications, and 3-year mortality. A per-protocol analysis was used. RESULTS: Twenty-nine patients in the SGB group and 28 patients in the control group were analyzed. The SGB group exhibited a significantly shorter time to flatus (mean [SD] hour, 20.52 [9.18] vs. 27.93 [11.69]; p = 0.012), accompanied by decreased plasma cortisol levels (mean [SD], postoperatively, 4.01 [3.42] vs 7.75 [3.13], p = 0.02). Notably, postoperative pain was effectively managed, evident by lower VAS scores at 6 h post-surgery in SGB-treated patients (mean [SD], 4.70 [0.91] vs 5.35 [1.32]; p = 0.040). Furthermore, patients in the SGB group experienced reduced hospital stay length (mean [SD], day, 6.61 [1.57] vs 8.72 [5.13], p = 0.042). CONCLUSIONS: Preoperative SGB emerges as a promising approach to enhance the postoperative recovery of patients undergoing laparoscopic CRC surgery.

Postoperative pain after single-visit root canal treatments in necrotic teeth comparing instruments' kinematics and apical instrumentation limits - a prospective randomized multicenter clinical trial.

OBJECTIVES: This prospective randomized multicenter clinical trial (PRMCT) investigated postoperative pain after single-visit root canal treatments in teeth affected by pulp necrosis (PN), and asymptomatic apical periodontitis (AAP) (with apical radiolucent areas) or normal periradicular tissues (without apical radiolucent areas) comparing different instruments' kinematics and apical instrumentation limits. METHODS: Before chemomechanical preparation, 240 patients/teeth were randomly distributed into four groups (n = 60) according to the instruments' kinematics (rotary or reciprocating) and apical instrumentation limits (with or without intentional foraminal enlargement [IFE]). After that, specimens were submitted to the same irrigation and obturation techniques, and the patients were referred to undergo the definitive restorations. No medication was prescribed, but the patients were instructed to take either paracetamol (750 mg every 6 h for three days) or ibuprofen (600 mg every 6 h for three days) in pain cases. Postoperative pain incidence and levels were assessed at 24-, 48-, and 72 h following treatment completion according to a verbal rating scale (VRS) following a score. The Kolmogorov-Smirnov test was applied to assess the normality of the data. Mann-Whitney U, Chi-square, Friedman's ANOVA, and Friedman's multiple 2 to 2 comparison tests were employed to identify potential significant statistical differences among the variables in the study groups (P < .05). RESULTS: Significant statistical differences were only observed among the groups considering tooth, periradicular status, and the occurrence of overfilling (sealer extrusion) (P < 0.00). Patients with teeth instrumented through rotary kinematics and without IFE experienced lower rates of postoperative pain; however, this difference was relevant only at 24 h (P < 0.05). CONCLUSIONS: Postoperative pain was lower after using a rotary file system (Profile 04) inserted up to the apical constriction (AC). However, this finding was just statistically meaningful at 24 h. TRIAL REGISTRATION: This PRMCT was approved by the Human Research Ethics Committee of the Paranaense University - UNIPAR, Francisco Beltrão, PR, Brazil (CAAE. 46,774,621.6.0000.0109) on 02/09/2021. It was registered at The Brazilian Registry of Clinical Trials - ReBEC (RBR-3r967t) on 01/06/2023, was performed according to the Principles of the Helsinki Declaration and is reported following the Consolidated Standards of Reporting Trials Statement.

The Effect of Depth of Anesthesia on Postoperative Pain in Laparoscopic Sleeve Gastrectomy: A Randomized Controlled Trial.

BACKGROUND: Patients with obesity are more sensitive to pain and more likely to have acute postoperative pain (APP). Studies have shown that the depth of anesthesia may affect the incidence of APP. The purpose of the study was to look into the connection between APP and depth of anesthesia in patients with obesity undergoing laparoscopic sleeve gastrectomy. METHODS: This is a prospective, double-blinded randomized clinical trial, 90 patients undergoing laparoscopic sleeve gastrectomy were randomly divided into two groups: the light anesthesia group (Bispectral Index of 50, BIS 50) and the deep anesthesia group (BIS 35). The degree of pain was evaluated by the visual analogue scale (VAS) at 0, 12, 24, 48, and 72 h after surgery. The use of analgesics, grade of postoperative nausea and vomiting (PONV), and the Quality of Recovery-15 (QoR-15) score were recorded. RESULTS: The VAS scores at rest or coughing at 0, 12, and 24 h after surgery in the BIS 35 group were lower than those in the BIS 50 group (P < 0.05). Fewer patients in the deep anesthesia group needed analgesia during the recovery period, and patient satisfaction was higher on the 3rd day after surgery (P < 0.015, P < 0.032, respectively). CONCLUSIONS: For patients with obesity, maintaining a deeper depth of anesthesia during surgery is beneficial to reduce APP causes less need for additional analgesic drugs, and improves patient satisfaction.

Preoperative anxiety and postoperative pain associated with cataract surgery under local anesthesia.

INTRODUCTION: Although cataract surgery is a routine outpatient surgery, anxiety and pain remain two significant concerns seen in patients. AIM: To describe preoperative anxiety and postoperative pain related to cataract surgery under local anesthesia and identify the factors determining their occurrence. METHODS: This is a cross-sectional, descriptive and analytical, study which included patients who underwent cataract surgery for the first eye in the ophthalmology department of Habib Bourguiba University Hospital in Sfax-Tunisia. Preoperative anxiety was assessed using the Amsterdam Preoperative Anxiety and Information Scale. Postoperative pain was measured using the visual analog scale. RESULTS: A total of 203 patients were included with a sex ratio (M/F) of 0.79. The average age was 67.73±9.4 years. The mean overall preoperative anxiety score was 10.8±5.2. The average score for the need for information among patients was 3.45±1.5. The most anxiety-provoking factor was the possibility of surgery failure and loss of the operated eye. The determining factors for anxiety were young age and female gender. The average postoperative pain score in our patients was 3.51±1.8. A weakly positive correlation was noted between pain and duration of the procedure. CONCLUSION: Managing anxiety and pain related to cataract surgery through preoperative education and adequate management is necessary to improve patient comfort and well-being.

Comparing immediate postoperative outcomes of different VATS approaches for anatomical lung resection: a single-centre retrospective study.

BACKGROUND: Video-assisted thoracic surgery (VATS) can be performed through 1 or more intercostal or subxiphoid ports. The aim of this study was to evaluate whether number and location of ports had an impact on early perioperative outcomes and postoperative pain after anatomical lung resection (ALR). METHODS: A search of the departmental electronic database identified all patients who underwent VATS ALR between June 2018 and June 2019. We stratified patients according to the surgical approach: 2-port VATS, 3-port VATS, and subxiphoid VATS. We extracted demographic and clinicopathologic data. We used univariate analysis with unpaired t tests and χ2 tests to compare these variables between the subgroups. RESULTS: We included 201 patients in the analysis. When patients were stratified by surgical approach, there was no difference in terms of age, disease load, length of surgery, postoperative complications, duration of pleural drainage, and length of hospital stay. Postoperative pain and morphine equivalent usage were also comparable between the groups. According to these results, number and location of VATS ports seemingly has no clinical impact on early postoperative outcomes. Limitations of the study include its retrospective nature, small sample size, and short follow-up interval. CONCLUSION: Our results suggest that incision location and the number of VATS ports is not associated with differences in the incidence of perioperative complications or postoperative pain. Given the limitations described above, further studies with longer follow-up intervals are required to explore the lasting impact of this surgical approach on quality of life.

Effect of transcutaneous electrical acupoint stimulation on the quality of postoperative recovery: a meta-analysis.

BACKGROUND: The purpose of the present study was to systematically delve into the efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) on the quality of recovery after general anesthesia. METHODS: Randomized controlled trials related to TEAS improving postoperative recovery quality were searched in Cochrane Library, Web of Science, Embase, PubMed, CNKI, VIP, Wanfang and Chinese biomedical database from the inception of each database to June 2023. After literature screening and data extraction, Stata15 software was employed for meta-analysis, and the quality of the included literature was evaluated utilizing ROB2. RESULTS: The study included 10 articles involving 2,383 patients in total. The meta-analysis results unveiled that TEAS could improve 24-hour and 48-hour postoperative QoR-40 scores as well as 24-hour postoperative QoR-40 dimension scores [WMD = 8.52, 95%CI (5.12, 11.91), P < 0.001; WMD = 1.99, 95%CI (0.91, 3.07), P < 0.001], emotional state [WMD = 1.38, 95%CI (0.66, 2.09), P < 0.001], physical comfort [WMD = 2.99, 95%CI (1.59, 4.39), P < 0.001], psychological support [WMD = 0.63, 95%CI (0.36, 0.90), P < 0.001], and physical independence [WMD = 0.76, 95%CI (0.22, 1.30), P = 0.006]; pain [WMD = 1.81, 95%CI (0.87, 2.75), P < 0.001]; decrease 24-hour postoperative VAS pain scores [WMD = -0.84, 95%CI (-1.45, -0.23), P = 0.007] and the incidence of postoperative nausea and vomiting [RR = 0.88, 95%CI (0.81, 0.97), P = 0.006; RR = 0.62, 95%CI (0.52, 0.73), P < 0.001]. CONCLUSION: TEAS can improve postoperative QoR-40 scores and the quality of recovery, relieve pain, and decrease the incidence of nausea and vomiting after surgery in patients who underwent general anesthesia.

Cosmetic surgery and associated chronic postsurgical pain: A cross-sectional study from Norway.

OBJECTIVES: Chronic postsurgical pain (CPSP) is a common postoperative sequela. Despite the increasing popularity of cosmetic surgeries, there is a notable lack of research on CPSP in this context, with existing studies focusing on breast surgeries only. To address existing gaps in knowledge, the objective of the present study was to investigate the self-reported prevalence of cosmetic surgery and associated CPSP among Norwegian adults. METHODS: An online questionnaire consisting of three questions inquiring prior cosmetic surgeries, associated CPSP, and whether participants had sought for pain management was constructed and distributed among adults residing in Norway. RESULTS: Between November 30, 2022 and December 16, 2022, 1,746 participants were recruited. 10% of respondents, 73.3% of which were female, affirmed to have undergone cosmetic surgery. About 1 in 4 of these was aged 18-29 years. The prevalence of CPSP was 12.6%. CPSP was five times more common among male, compared to female respondents. While about two thirds of participants indicating to have experienced CPSP were aged 18-29 years, CPSP was much less common among individuals of other ages. CONCLUSION: Consistent with international trends, there appears to be a young and growing population of cosmetic surgery consumers in Norway. According to our results, about 1 in 8 of these might be affected by CPSP, a condition that is notoriously hard to treat and weighting heavily on public healthcare and social welfare systems. Large-scale longitudinal studies further investigating the topic are thus urgently needed.

Effects of postoperative environmental noise on surgery induced pain: Evidence based on a prospective observational study.

CONTEXT: Many patients recovering from surgery in wards are disturbed by environmental noise. However, the effects of environmental noise on postoperative pain are unclear. OBJECTIVES: This study aimed to assess the association between postoperative noise and pain. METHODS: This prospective study included 182 women who underwent cesarean sections. Postoperative noise was continuously recorded, and pain intensity at rest was assessed using a numerical rating scale (NRS) for 0-6, 6-12, 12-18, and 18-24 h after the patients were returned to the ward. Cumulative pain scores were calculated by summing the NRS scores at each time point and comprised the primary outcome. The maximum pain NRS score and analgesic consumption during the 24 h after surgery were also recorded. RESULTS: Mean environmental noise intensity during the daytime was an independent factor for cumulative pain scores, maximum pain scores, and analgesic use during the first postoperative 24 h (ß, 0.37; 95% CI, 0.21-0.53 and ß, 0.12; 95% CI, 0.07-0.17; P < 0.001 for both; ß, 0.86; 95% CI, 0.25-1.46; P = 0.006). Cumulative and maximum NRS pain scores as well as the incidence of NRS ≥ 4 were significantly higher in patients under mean daytime environmental noise of ≥58, than <58 decibels (dB) (8.0 [6.0-11.3] vs. 6.0 (5.0-7.0); 3.0 [2.0-4.0] vs. 2.0 [2.0-2.0, and 25.6% vs. 11.0%; RR, 2.32; 95% CI, 1.19-4.54, respectively; P < 0.001 for all). CONCLUSIONS: Higher-level postoperative noise exposure was associated with more severe postoperative pain and increased analgesic needs, as well as a higher incidence of moderate-to-severe pain in patients recovering from cesarean delivery. Our findings indicate that reducing environmental ward noise might benefit for postoperative pain management.

Analysis of Risk Factors for Postoperative Dysuria in Patients Undergoing Thoracotomy under General Anaesthesia.

BACKGROUND: Thoracotomy under general anaesthesia is one of the most difficult surgeries and is prone to result in postoperative complications. This study explored risk factors for postoperative dysuria in patients undergoing thoracotomy under general anaesthesia to provide a reference for the formulation and selection of subsequent clinical management programs. METHODS: Patients undergoing thoracotomy under general anaesthesia (n = 179) admitted to our hospital from June 2019 to June 2021 were selected. They were divided into dysuria group (n = 79) and normal urination group (n = 100) according to whether they had dysuria after surgery. Logistic regression analysis was conducted to explore risk factors affecting postoperative dysuria. RESULTS: Univariate analysis showed that dysuria was related to gender, age, surgical time, intraoperative and postoperative infusion volume, usage time of analgesic pump and retention time of urethral catheter (p < 0.001). Logistic regression analysis showed that male, age ≥60 years, surgical time ≥120 min, intraoperative infusion volume >1200 mL, postoperative infusion volume >800 mL, analgesic pump usage time ≥18 h and urethral catheter retention time of ≥72 h were risk factors for postoperative dysuria. CONCLUSIONS: The occurrence of postoperative dysuria in patients undergoing thoracotomy under general anaesthesia is related to gender, age, surgical time, intraoperative infusion volume, postoperative infusion volume, usage time of analgesic pump and retention time of urethral catheter. Clinical attention should be given to this patient group, and targeted intervention measures should be implemented.

Chronic postsurgical pain: A European survey.

BACKGROUND: Chronic postsurgical pain (CPSP) is a clinical problem, and large prospective studies are needed to determine its incidence, characteristics, and risk factors. OBJECTIVE: To find predictive factors for CPSP in an international survey. DESIGN: Observational study. SETTING: Multicentre European prospective observational trial. PATIENTS: Patients undergoing breast cancer surgery, sternotomy, endometriosis surgery, or total knee arthroplasty (TKA). METHOD: Standardised questionnaires were completed by the patients at 1, 3, and 7 days, and at 1, 3, and 6 months after surgery, with follow-up via E-mail, telephone, or interview. MAIN OUTCOME MEASURE: The primary goal of NIT-1 was to propose a scoring system to predict those patient likely to have CPSP at 6 months after surgery. RESULTS: A total of 3297 patients were included from 18 hospitals across Europe and 2494 patients were followed-up for 6 months. The mean incidence of CPSP at 6 months was 10.5%, with variations depending on the type of surgery: sternotomy 6.9%, breast surgery 7.4%, TKA 12.9%, endometriosis 16.2%. At 6 months, neuropathic characteristics were frequent for all types of surgery: sternotomy 33.3%, breast surgery 67.6%, TKA 42.4%, endometriosis 41.4%. One-third of patients experienced CPSP at both 3 and 6 months. Pre-operative pain was frequent for TKA (leg pain) and endometriosis (abdomen) and its frequency and intensity were reduced after surgery. Severe CPSP and a neuropathic pain component decreased psychological and functional wellbeing as well as quality of life. No overarching CPSP risk factors were identified. CONCLUSION: Unfortunately, our findings do not offer a new CPSP predictive score. However, we present reliable new data on the incidence, characteristics, and consequences of CPSP from a large European survey. Interesting new data on the time course of CPSP, its neuropathic pain component, and CPSP after endometriosis surgery generate new hypotheses but need to be confirmed by further research.

Outpatient pain service in trauma and orthopaedic surgery.

INTRODUCTION: Chronic pain is a common complication after surgery and trauma. The incidence of chronic pain may potentially be reduced by effective management of severe acute pain, in hospital and during the subacute post-operative phase at home. METHODS: This was a cohort study from an outpatient follow-up service for patients with pain at discharge after orthopaedic surgery and trauma in a level 1 university hospital setting. The patients' charts were reviewed. Demographics, diagnosis and treatment were registered. The objective of this study was to describe the first five years of experience with this service. RESULTS: A total of 261 patients were included. The median age was 39 (interquartile range (IQR): 26-76) years, and 53% were men. The median pain duration was ten (IQR: 5-22) months. Neuropathic pain was diagnosed in 83% of patients. Complex regional pain syndrome was diagnosed in 10% and suspected in 8%. Before the consultation, 48% were using paracetamol and/or non-steroid anti-inflammatory drugs (NSAIDs), 25% opioids, and 36% used gabapentioids or antidepressants. After their consultation, only 13% used paracetamol and/or NSAIDs and 8% opioids, whereas 86% were treated with gabapentinoids or antidepressants. A plan for opioid weaning was provided for all patients if opioids were continued (8%). CONCLUSIONS: Establishing an outpatient pain service for persistent pain after surgery and trauma may encourage the use of analgesia regimens that are in accordance with international guidelines and ensure that opioids are not continued inappropriately. FUNDING: None. TRIAL REGISTRATION: Not relevant.

Operation-specific risk of postoperative nausea: a cross-sectional study comparing 72 procedures.

OBJECTIVES: Determination of the procedure-specific, risk-adjusted probability of nausea. DESIGN: Cross-sectional analysis of clinical and patient-reported outcome data. We used a logistic regression model with type of operation, age, sex, preoperative opioids, antiemetic prophylaxis, regional anaesthesia, and perioperative opioids as predictors of postoperative nausea. SETTING: Data from 152 German and Austrian hospitals collected in the Quality Improvement in Postoperative Pain Treatment (QUIPS) registry from 2013 to 2022. Participants completed a validated outcome questionnaire on the first postoperative day. Operations were categorised into groups of at least 100 cases. PARTICIPANTS: We included 78 231 of the 293 947 participants from the QUIPS registry. They were 18 years or older, willing and able to participate and could be assigned to exactly one operation group. MAIN OUTCOME MEASURES: Adjusted absolute risk of nausea on the first postoperative day for 72 types of operation. RESULTS: The adjusted absolute risk of nausea ranged from 6.2% to 36.2% depending on the type of operation. The highest risks were found for laparoscopic bariatric operations (36.2%), open hysterectomy (30.4%), enterostoma relocation (29.8%), open radical prostatectomy (28.8%), laparoscopic colon resection (28.6%) and open sigmoidectomy (28%). In a logistic regression model, male sex (OR: 0.39, 95% CI 0.37 to 0.41, p<0.0001), perioperative nausea and vomiting prophylaxis (0.73, 0.7 to 0.76, p<0.0001), intraoperative regional anaesthesia (0.88, 0.83 to 0.93, p<0.0001) and preoperative opioids for chronic pain (0.74, 0.68 to 0.81, p<0.0001) reduced the risk of nausea. Perioperative opioid use increased the OR up to 2.38 (2.17 to 2.61, p<0.0001). CONCLUSIONS: The risk of postoperative nausea varies considerably between surgical procedures. Patients undergoing certain types of operation should receive special attention and targeted prevention strategies. Adding these findings to known predictive tools may raise awareness of the still unacceptably high incidence of nausea in certain patient groups. This may help to further reduce the prevalence of nausea. TRIAL REGISTRATION NUMBER: DRKS00006153; German Clinical Trials Register; https://drks.de/search/de/trial/DRKS00006153.

Predictors and influence of postoperative moderate-to-severe pain of PACU in the patients with malignancy.

BACKGROUND: This study was identified the risk factors for and designed to investigate influence of postoperative moderate-to-severe pain of post anaesthesia care unit (PACU) in patients with malignancy. METHODS: A retrospective study was performed on 22,600 cancer patients with malignancy who underwent elective radical surgery in the new hospital of First Affiliated Hospital of Wenzhou Medical University, between January 2016 and June 2021. All patients were transferred to the PACU after tracheal extubation. Patients were divided into two groups according to a visual analogue scale (VAS) score of > 3: the no-moderate-severe-pain group and moderate-to-severe-pain group. Data pertaining to demographic, surgical, anaesthetic, and other factors were recorded. Lasso and logistic regression analysis was performed to explore the risk factors, then a nomogram was constructed to predict the moderate-severe-pain in the PACU. Validation was performed by using another 662 cancer patients in old hospital. The ROC curves and calibration curve were used to evaluate the accuracy and predictive ability of the nomogram. RESULTS: The incidence of postoperative moderate-to-severe pain of PACU in patients with malignancy was 1.42%. Gender, type of surgery, postoperative use of PCA, intraoperative adjuvant opioid agonists, NSAIDS, epidural analgesia, duration of anaesthesia, intraoperative massive haemorrhage, PACU vomiting were independent predictors for postoperative moderate-to-severe pain of PACU in the patients with malignancy. The area under the ROC curve of the predictive models in the primary and validation groups were 0.817 and 0.786, respectively. Moderate-to-severe pain in the PACU correlated with hypertension, hyperglycaemia, agitation, and hypoxemia (P < 0.05). CONCLUSIONS: The prediction model for postoperative moderate-to-severe pain of PACU in patients with malignancy has good predictive ability and high accuracy, which is helpful for PACU medical staff to identify and prevent postoperative moderate-to-severe pain in advance. TRIAL REGISTRATION: The study was approved by the Clinical Research Ethics Committee of the First Affiliated Hospital of Wenzhou Medical University (No.KY2021-097) and registered in the Chictr.org.cn registration system on 06/12/2021 (ChiCTR2100054013).

[Characteristics and influencing factors of early pain in patients after total knee arthroplasty].

OBJECTIVE: To investigate the current status of early pain in patients after total knee arthroplasty under enhanced recovery mode and analyze the influencing factors. METHODS: In the study, 142 patients with total knee arthroplasty of a hospital in Beijing were investigated by convenient sampling. Visual analog scale (VAS) was used to describe the degree of pain (including resting pain and activity pain) within 3 days after operation, and the nature and location of pain and satisfaction with the analgesic effect of the patients were recorded. The influencing factors included age, gender, place of residence, education level, body mass index (BMI), years of pain, chronic medical history, surgical history, surgical duration, whether to indwell a drainage tube, type of carer, severity of the disease, sleep quality, anxiety, depression, and preoperative pain level. The investigation tools of influencing factors were the general information questionnaire of patients, pain assessment questionnaire, Pittsburgh sleep quality index (PSQI), self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Firstly, single factor analysis was carried out on the included influencing factors, and then multiple stepwise regression analysis was carried out on the statistically significant variables to clarify the main influencing factors of early pain in patients after total knee arthroplasty. RESULTS: The peak pain of the patient occurred at night on the first postoperative day and in the afternoon on the second postoperative day, with resting pain scores of (2.5±1.2) and (2.7±1.1), and activity pain scores of (3.8±1.5) and (4.0±1.6); the most common pain site was posterior knee pain (68, 47.9%), followed by anterior knee combined with posterior knee pain (32, 22.5%), anterior knee pain (27, 19.1%), anterior knee combined with medial knee pain (10, 7.0%), and anterior knee combined with lateral knee pain (5, 3.5%); the nature of pain was mostly composed of soreness combined with swelling pain (58, 40.8%), while the rest included simple soreness (26, 18. 3%), simple swelling pain (24, 16.9%), hot burning pain (10, 7.0%), pricking pain (9, 6.3%), spasmodic traction pain (5, 3.5%), tearing pain (4, 2.8%), knife cutting pain (3, 2.2%), and stabbing pain combined with soreness (3, 2.2%); the patients who were satisfied and very satisfied with the analgesic effect were 114 (80.3%). The results of univariate analysis showed that there were significant differences in sleep quality, disease severity, types of care-givers and depression score (P<0.05). The results of multiple stepwise regression analysis showed that the main factors affecting the patients' early postoperative pain were preoperative sleep quality, depression, the Knee Society score and the type of care (P=0.002). CONCLUSION: Most patients under enhanced recovery after surgery are satisfied with the effect of pain control after operation. Medical staff can carry out predictive intervention in patients' sleep quality, depression to reduce the patients' early postoperative pain. At the same time, the research results suggest that choosing family members to accompany the patients can effectively improve the patients' early postoperative pain experience.

Association of chronic poststernotomy pain and health-related quality of life: a prospective cohort study.

PURPOSE: Chronic poststernotomy pain (CPSP) after cardiac surgery is multifactorial and impacts patient recovery. We aimed to evaluate the association between CPSP severity and health-related quality of life at six months after cardiac surgery. METHODS: This was a single-centre prospective cohort study of patients who underwent cardiac surgery with median sternotomy between September 2020 and March 2021. Telephone interviews were conducted at six and 12 months postoperatively using the Short Form McGill Pain Questionnaire and the EQ-5D-5L. Strength of correlation was described using Spearman's correlation coefficient. Multivariable regression analysis was used to account for confounding variables. RESULTS: A total of 252 patients responded to the six-month interview (response rate, 65%). The mean (standard deviation) age of respondents was 65 (13) yr. Twenty-nine percent of respondents (72/252) reported CPSP at six months, and 14% (41/252) reported more than mild pain (score ≥ 2/5). At 12 months, of the 89% (64/72) patients who responded, 47% (30/64) still reported pain. The strength of the correlation between pain scores and EQ-5D-5L was weak (Spearman's correlation coefficient, -0.3). Risk factors for CPSP at six months included higher pain score on postoperative day 1, history of chronic pain prior to surgery, and history of depression. Intraoperative infusion of dexmedetomidine or ketamine was associated with a reduced risk of CPSP at six months. CONCLUSION: Chronic poststernotomy pain still affects patient recovery at six and 12 months after cardiac surgery. The severity of that pain is poorly correlated with patients' quality of life.

RéSUMé: OBJECTIF: La douleur chronique post-sternotomie (DCPS) après une chirurgie cardiaque est multifactorielle et a un impact sur le rétablissement des patient·es. Nous avons cherché à évaluer l'association entre la sévérité de la DCPS et la qualité de vie liée à la santé six mois après la chirurgie cardiaque. MéTHODE: Il s'agissait d'une étude de cohorte prospective monocentrique portant sur des patient·es ayant bénéficié d'une chirurgie cardiaque avec sternotomie médiane entre septembre 2020 et mars 2021. Des entrevues téléphoniques ont été menées à six et 12 mois après l'opération en se servant du questionnaire abrégé de McGill sur la douleur et de l'EQ-5D-5L. La force de corrélation a été décrite à l'aide du coefficient de corrélation de Spearman. Une analyse de régression multivariée a été utilisée pour tenir compte des variables confondantes. RéSULTATS: Au total, 252 patient·es ont répondu à l'entrevue à six mois (taux de réponse de 65 %). L'âge moyen (écart type) des répondant·es était de 65 (13) ans. Vingt-neuf pour cent des personnes répondantes (72/252) ont déclaré avoir été atteintes de DCPS à six mois, et 14 % (41/252) ont signalé une douleur plus que légère (score ≥ 2/5). À 12 mois, sur les 89 % (64/72) personnes ayant répondu, 47 % (30/64) signalaient encore de la douleur. La force de la corrélation entre les scores de douleur et l'EQ-5D-5L était faible (coefficient de corrélation de Spearman, −0,3). Les facteurs de risque de DCPS à six mois comprenaient un score de douleur plus élevé au jour 1 postopératoire, des antécédents de douleur chronique avant la chirurgie et des antécédents de dépression. Une perfusion peropératoire de dexmédétomidine ou de kétamine a été associée à une réduction du risque de DCPS à six mois.

Factors associated with pain and functional impairment five years after total knee arthroplasty: a prospective observational study.

BACKGROUND: Few studies have evaluated the associations between preoperative factors and pain and physical function outcomes after total knee arthroplasty (TKA) from a mid-term perspective. Identification of such factors is important for optimizing outcomes following surgery. Thus, we examined the associations between selected preoperative factors and moderate to severe pain and pain-related functional impairment as measured using the Brief Pain Inventory (BPI), five years after TKA in patients with knee osteoarthritis. METHODS: In this prospective observational study, all patients scheduled for primary unilateral TKA for osteoarthritis were consecutively recruited. Preoperative factors identified from previous meta-analyses were included to assess their associations with pain severity and pain-related functional impairment five years after TKA. Pain severity was the primary outcome, while pain-related functional impairment was the secondary outcome. The BPI was used to evaluate outcomes five years post-TKA. Statistically significant factors from univariate regressions were entered into a multiple logistic regression model to identify those with the strongest associations with pain severity or pain-related functional impairment five years after TKA. RESULTS: A total of 136 patients were included, with a mean age of 67.7 years (SD 9.2) and a majority being female (68%). More severe preoperative pain (OR = 1.34, 95% CI [1.03 to 1.74]), more painful sites (OR = 1.28., 95% CI [1.01 to 1.63]), and more severe anxiety symptoms (OR = 1.14., 95% CI [1.01 to 1.28]) were associated with increased likelihood of moderate to severe pain five years after TKA surgery, while more severe osteoarthritis (OR = 0.13, 95% CI [0.03 to 0.61]) was associated with reduced likelihood of moderate to severe pain five years after TKA. More severe anxiety symptoms (OR = 1.25, 95% CI [1.08 to 1.46]) were also associated with increased likelihood of moderate to severe pain-related functional impairment five years after surgery, while male sex (OR = 0.23, 95% CI [0.05 to 0.98]) was associated with reduced likelihood of pain-related functional impairment five years after surgery. CONCLUSION: The identified preoperative factors should be included in larger prognostic studies evaluating the associations between preoperative factors and mid-term pain severity and physical function outcomes after TKA surgery.

Association of preoperative neutrophil-lymphocyte ratios with the emergence delirium in pediatric patients after tonsillectomy and adenoidectomy: an observational prospective study.

PURPOSE: The study aimed to investigate potential risk factors for emergence delirium (ED) in pediatric patients after tonsillectomy and adenoidectomy (T&A). METHODS: This prospective, single-center observational study enrolled children aged 3-7 years who underwent T&A under general anesthesia. ED was assessed according to DSM-IV or V criteria. Receiver operating characteristic curve analysis was performed to evaluate the predicative and cut-off values of risk factors, including age, preoperative anxiety level, postoperative pain and neutrophil-lymphocyte ratio (NLR) for ED. Univariate and multivariate logistic regression analyses were performed to investigate risk factors for ED. RESULTS: 94 pediatric patients who underwent T&A were enrolled and 19 developed ED (an incidence of 25.3%). Receiver operating characteristic analysis indicated that preoperative NLR was a significant predictor of ED with a cut-off value of 0.8719 and an area under the curve (AUC) of 0.671 (95% confidence interval (CI) 0.546-0.796, P = 0.022). Preoperative NLR (< 0.8719) and postoperative pain were independent risk factors associated with ED (odds ratio: 0.168, 95% CI 0.033-0.858, P = 0.032; odds ratio: 7.298, 95% CI 1.563-34.083, P = 0.011) according to multivariate logistic regression analysis. CONCLUSIONS: Preoperative NLR level and postoperative pain were independent risk factors for ED in pediatric patients undergoing T&A.

Current trends and outcomes for unilateral groin hernia repairs in the United States using the Abdominal Core Health Quality Collaborative database: A multicenter propensity score matching analysis of 30-day and 1-year outcomes.

BACKGROUND: Different unilateral groin hernia repair approaches have been developed in the last 2 decades. The most commonly done approaches are open inguinal hernia repair by the Lichenstein technique, laparoscopic approach by either total extraperitoneal or transabdominal preperitoneal, and robotic transabdominal preperitoneal approach. Hence, this study aimed to compare early and late postoperative outcomes in patients who underwent unilateral robotic transabdominal preperitoneal, laparoscopic transabdominal preperitoneal, and laparoscopic total extraperitoneal, and open groin hernia repair using a United States national hernia database, the Abdominal Core Health Quality Collaborative Database. METHODS: Prospectively collected data from the Abdominal Core Health Quality Collaborative database was retrospectively reviewed, including all adult patients who underwent elective unilateral groin hernia repair from 2015 to 2022, with a 1:1 propensity score match analysis conducted for balanced groups. The univariate analysis compared the groups across the preoperative, intraoperative, and postoperative timeframes. RESULTS: The Abdominal Core Health Quality Collaborative database identified 14,320 patients who underwent elective unilateral groin hernia repair and had documented 30 days of follow-up. Propensity score matching stratified 1,598 patients to each group (total of 6,392). The median age was 64 years (interquartile range 53-74) for open groin hernia repair, whereas 60 (interquartile range 47-69) for laparoscopic transabdominal preperitoneal, 62 (interquartile range 48-70) for laparoscopic total extraperitoneal, and 60 (interquartile range 47-70) for robotic transabdominal preperitoneal were noted. Open groin hernia repair had more American Society of Anesthesiologists score 4 (52, 3%) patients (P < .001). A painful bulge was the most common indication (>85%). Operating room time >2 hours was more significant in the robotic transabdominal preperitoneal group (123, 8%; P < .001). Seroma rate was higher in the laparoscopic transabdominal preperitoneal (134, 8%; P < .001). A 1-year analysis had 1,103 patients. Hematoma, surgical site infection, readmission, reoperation, and hernia recurrence at 30 days or 1 year did not differ, with an overall recurrence rate of 6% (n = 67) at 1 year (P = .33). In patients with body mass index ≥30 kg/m2, the robotic approach had lower rates of surgical site occurrence (n = 12, 4%; P = .002) and seroma (n = 5, 2%; P < .001) compared with the other groups. When evaluating recurrence 1 year after surgery, the robotic transabdominal preperitoneal group had 10% versus 18% open groin hernia repair, 11% laparoscopic transabdominal preperitoneal, and 18% laparoscopic total extraperitoneal, but it was not statistically significant (P = .53). CONCLUSION: There was no difference in readmission, reoperation, and surgical site infection among the surgical techniques at 30 days. However, laparoscopic transabdominal preperitoneal was associated with more seromas. Hernia recurrence at 1 year was similar across groups; the robotic approach had the lowest recurrence rate among all 3 repairs but did not reach statistical significance. The robotic approach performed better in patients with a body mass index of 30 kg/m2 for surgical site occurrence and seroma than in other surgical techniques.

Outcomes of conventional and advanced energy devices in laparoscopic surgery: a systematic review.

INTRODUCTION: Hemostasis is an important step in all surgical procedures. Mechanical methods of hemostasis have been gradually abandoned in favor of electrosurgery. The aim of this systematic review was to evaluate the effectiveness of electrosurgical instruments utilized in minimally invasive gynecological procedures. MATERIAL AND METHODS: We performed a systematic review, including randomized controlled trials, prospective and retrospective studies, comparing the outcomes of different energy devices (EDs) used in laparoscopic gynecologic surgeries. We extracted data about blood loss (BL), mean operative time, post-operative pain, hospital stay and complications associated with each electrosurgical device. RESULTS: We included 30 studies reporting comparative outcomes concerning conventional (bipolar and monopolar) and innovative EDs (Harmonic scalpel, LigaSure, Plasma kinetic gyrus, Thunderbeat, EnSeal, Marseal, Caiman and ALAN). New EDs were found to be more efficient in complex surgeries due to less intraoperative BL and shorter operative time. No significant decrease in hospital stay, post-operative pain or complications was found with the use of new energy instruments. CONCLUSIONS: Although new electrosurgical devices seem an appealing and safer option, there is still insufficient evidence for one vessel-sealing technology to be considered superior to another. Therefore, monopolar and conventional bipolar (CB) are still widely used in laparoscopic gynecology.

Comparison of postoperative pain between transoral and conventional thyroidectomy: a propensity score-matched analysis.

BACKGROUND: The extent of postoperative pain following transoral thyroidectomy is not well-understood and remains a subject of debate. This study aims to analyze and compare postoperative pain levels between patients undergoing transoral and conventional transcervical thyroidectomy. METHODS: A prospective evaluation on postoperative pain was conducted in 310 patients undergoing conventional thyroidectomy and 194 undergoing transoral thyroidectomy. Pain levels were evaluated using the numerical rating scale (NRS, ranging from 0 to 10) through preoperative and postoperative questionnaires at specified time points: 1, 3, and 6 days, and 1 and 3 months following surgery. Propensity score-matched analysis was carried out based on six covariates: sex, age, body mass index, extent of thyroidectomy, tumor size, and central neck dissection. RESULTS: After propensity score matching based on the six covariates, 121 patient pairs were identified from each group. Within this matched cohort, postoperative pain scores significantly worsened 1 day after surgery but showed progressive recovery up to 3 months post-surgery in both groups. The transoral group exhibited higher postoperative pain scores than the conventional group from day 1 (4.43 ± 2.6 vs. 3.11 ± 2.5, p < 0.001) to day 6 (1.76 ± 1.9 vs. 1.13 ± 1.6, p = 0.016) post-surgery, with no significant difference noted at 1 month. Among transoral procedures, pain scores were significantly higher for the endoscopic approach compared to the robotic approach on days 1 (5.52 ± 2.3 vs. 4.29 ± 2.3, p = 0.028) and 3 (3.52 ± 2.5 vs. 2.64 ± 2.0, p = 0.047) post-surgery. CONCLUSIONS: Postoperative pain was significantly higher in transoral thyroidectomy compared to conventional thyroidectomy up to 6 days post-surgery. Within the transoral group, the robotic procedure resulted in lower pain levels than the endoscopic approach during the early postoperative period.
