Effect of Shoulder Movement Routine on Postoperative Shoulder Pain in Total Laparoscopic Hysterectomy: A Randomized Clinical Trial.

Background and Objectives: Postoperative shoulder pain is a common issue after total laparoscopic hysterectomy (TLH). This study evaluated the impact of a shoulder movement routine on postoperative shoulder pain in women undergoing uncomplicated TLH. Materials and Methods: An open-label randomized clinical trial included women without prior shoulder pain undergoing TLH between 20 January and 20 March 2024. Participants were randomized into two groups: Group 1 (n = 36) received a shoulder movement routine, while Group 2 (control, n = 39) performed a hand movement routine. Shoulder pain was assessed using the visual analog scale (VAS) at 6 h, 24 h, and 7 days postoperatively. Results: Seventy-five women participated. No significant differences were found between the groups regarding demographic variables, surgery duration, or hospital stay. Shoulder pain scores (VAS) at three time points (6 h, 24 h, and 7 days) showed no significant differences between groups (p = 0.57, p = 0.69, and p = 0.91, respectively). Similarly, there were no significant differences in incisional or abdominal pain. Conclusions: The shoulder movement routine did not significantly reduce postoperative shoulder pain in women undergoing uncomplicated TLH.

Exploration of the mechanism underlying the therapeutic effect of electroacupuncture at chengshan acupoint on post-hemorrhoidectomy anal pain: Insights from the mAChRs/IP3-Ca2+-CaM signaling pathway.

OBJECTIVE: In the context of postoperative anal pain, understanding the intricate mechanisms and effective interventions is paramount. This study investigates the role of Muscarinic Acetylcholine Receptors (mAChRs) and the IP3-Ca2+-CaM signaling pathway in a rat model of postoperative anal pain, exploring the potential analgesic effects of electroacupuncture. METHODS: Comprehensive approaches involving mechanical sensitivity assays, Western blotting, immunohistochemistry, and intracellular calcium concentration measurement were used. RESULTS: The authors found elevated mAChRs expression in the postoperative pain model. Antagonizing mAChRs reduced pain sensitivity and attenuated the IP3-Ca2+-CaM pathway. Remarkably, electroacupuncture treatment further mitigated pain, potentially by suppressing this signaling cascade. INTERPRETATION: These findings reveal a novel connection between mAChRs and the IP3-Ca2+-CaM pathway in postoperative anal pain and suggest electroacupuncture as a promising avenue for pain relief through these mechanisms, offering insights into innovative strategies for postoperative pain management.

Unveiling the impact of opioid-free postoperative regimens in ureteroscopy: a comprehensive systematic review and meta-analysis.

INTRODUCTION: Ureteroscopy (URS) and retrograde intrarenal surgery (RIRS) are minimally invasive urologic procedures that are commonly used to treat kidney stones. However, they often result in significant postoperative pain. Historically, patients undergoing these surgeries have predominantly been managed with opioids, which has contributed to the escalating global complications associated with these drugs, including abuse and addiction. As a result, over the recent years, many healthcare centers have made efforts to minimize opioid use, opting instead for safer alternative medications. In this study, we aim to compare the efficacy of both opioid and opioid-free pain management regimens following URS or RIRS procedures. EVIDENCE ACQUISITION: A systematic search was conducted in MEDLINE, Embase, Scopus, Cochrane, LILACS, and Google Scholar. We included studies that compared opioid-based and opioid-free postoperative care for managing pain in patients who underwent URS or RIRS for lithotripsy. Our primary outcome of interest was the frequency of postoperative emergency department (ED) visits. Secondary outcomes included pain-related phone calls, postoperative unexpected encounters, need for opioids at discharge, and patients with opioid refills. EVIDENCE SYNTHESIS: We retrieved 10 articles, encompassing 6786 patients in the opioid group and 5276 patients in the opioid-free group. Overall, our findings lean towards favoring the opioid-free regimen, revealing notable differences between the groups. Opioid-free regimen was associated with less ED visits (OR=0.67; 95% CI: 0.58, 0.77; P=0.00001; I2=0%) and required less opioids at discharge (OR=0.11; 95% CI 0.02, 0.64; P=0.01; I2=89%). CONCLUSIONS: Through statistically superior results, our meta-analysis suggests that an opioid-free regimen outperforms the use of opioids after URS or RIRS, particularly in terms of pain management.

Efficacy of periarticular local infiltrative anaesthesia (modified Ranawat cocktail regimen) for postoperative pain control and reducing morbidity in total knee arthroplasty: a tertiary centre retrospective study.

INTRODUCTION: surgical pain is managed with multi-modal anesthesia in total knee arthroplasty (TKA). It is dubious whether including local infiltrative anaesthesia (LIA) before wound closure provides adequate pain control and decreases morbidity. MATERIAL AND METHODS: this was a retrospective conducted to assess postoperative pain control, morbidity index, and opioid consumption in 116 patients who underwent TKA and were divided into two groups based on LIA (Modified Ranawat Regimen) or normal saline infiltration in the wound. RESULTS: the mean NRS score was significantly lower in LIA group (3.2) as compared to the control group (3.9) in the first 24 hours. Functional milestones were relatively achieved earlier in LIA group but the values were not significant. Tramadol consumption was remarkably higher in the control group as compared to LIA group on day 1 and 2. As per the morbidity index the mean score on day one was 16.18 and 23.40 which decreased to 6.37 and 9.21 by day three in LIA and control group respectively indicating morbidity has decreased but more so in LIA group. CONCLUSION: our study concludes that use of modified cocktail regimen in the knee effectively decreased morbidity with excellent to good results, declining NRS score, minimal rescue analgesia requirement, early ambulation with better safety.

INTRODUCCIÓN: el dolor quirúrgico se trata con anestesia multimodal en la artroplastia total de rodilla (ATR). Es dudoso que incluir anestesia local infiltrativa (LIA) antes del cierre de la herida proporcione un control adecuado del dolor y disminuya la morbilidad. MATERIAL Y MÉTODOS: se realizó una retrospectiva para evaluar el control del dolor posoperatorio, el índice de morbilidad y el consumo de opioides en 116 pacientes sometidos a ATR y se dividieron en dos grupos según el LIA (régimen de Ranawat modificado) o la infiltración de solución salina normal en la herida. RESULTADOS: la puntuación media NRS fue significativamente menor en el grupo LIA (3.2) en comparación con el grupo control (3.9) en las primeras 24 horas. Los hitos funcionales se alcanzaron relativamente antes en el grupo LIA, pero los valores no fueron significativos. El consumo de tramadol fue notablemente mayor en el grupo de control en comparación con el grupo de LIA los días 1 y 2. Según el índice de morbilidad, la puntuación media el día uno fue 16.18 y 23.40, que disminuyó a 6.37 y 9.21 en el día tres en el grupo de LIA y control, respectivamente, lo que indica que la morbilidad ha disminuido, pero más en el grupo LIA. CONCLUSIÓN: nuestro estudio concluye que el uso de un régimen de cóctel modificado en la rodilla disminuyó efectivamente la morbilidad con resultados excelentes a buenos, una disminución de la puntuación NRS, un requisito mínimo de analgesia de rescate y una deambulación temprana con mayor seguridad.

[Efficacy of transdermal lidocaine 5% patches in postoperative analgesia following knee arthroscopy]. / Efectividad del parche transdérmico de lidocaína 5% en la analgesia postoperatoria después de la artroscopía de rodilla.

INTRODUCTION: knee arthroscopy is a common orthopedic procedure associated with postoperative pain, so optimizing pain management is essential for patient recovery and satisfaction. Lidocaine, a local anesthetic with well-established safety profiles, offers a potential alternative to traditional analgesic methods. Research regarding lidocaine patches has been conducted in several types of surgeries (laparoscopy, gynecological surgery, prostatectomy, etc.) showing promising results for some. This study investigates the effectiveness of transdermal lidocaine 5% patches as a novel approach to postoperative analgesia after knee arthroscopy. MATERIAL AND METHODS: a randomized, single-blind, placebo-controlled trial was conducted with participants undergoing knee arthroscopy. Patients were divided into two groups: one receiving transdermal lidocaine 5% patches and the other a placebo, both along traditional postoperative pain management, and using opioid only in cases with moderate-severe pain. Pain scores, opioid consumption, and patient-reported outcomes were assessed at various postoperative intervals. RESULTS: there was a significant reduction in pain scores and opioid consumption in the lidocaine patch group compared to the placebo group. CONCLUSIONS: transdermal lidocaine 5% patches emerge as a promising adjunct to postoperative pain management in knee arthroscopy patients. Their ease of application, minimal side effects, and opioid-sparing effects contribute to a multifaceted analgesic approach. This study underscores the potential of transdermal lidocaine patches in enhancing the overall postoperative experience for knee arthroscopy patients, advocating for their consideration in clinical practice.

INTRODUCCIÓN: la artroscopía de rodilla es un procedimiento ortopédico común asociado con dolor postoperatorio, por lo que optimizar el manejo del dolor es esencial para la recuperación y la satisfacción del paciente. La lidocaína, un anestésico local con perfiles de seguridad bien establecidos, ofrece una alternativa potencial a los métodos analgésicos tradicionales. Se ha llevado a cabo investigación sobre los parches de lidocaína en diversos tipos de cirugías (laparoscopía, cirugía ginecológica, prostatectomía, etcétera), mostrando resultados prometedores en algunos casos. MATERIAL Y MÉTODOS: se realizó un ensayo clínico aleatorizado, ciego simple y controlado con placebo que incluyó participantes sometidos a artroscopía de rodilla. Los pacientes fueron divididos en dos grupos: uno recibió parches transdérmicos de lidocaína al 5% y otro un placebo, ambos junto con el manejo tradicional del dolor postoperatorio y utilizando opioides sólo en casos de dolor moderado a severo. Se evaluaron las puntuaciones de dolor, el consumo de opioides y los resultados informados por los pacientes en varios intervalos postoperatorios. RESULTADOS: se registró una reducción significativa en las puntuaciones de dolor y el consumo de opioides en el grupo de parches de lidocaína en comparación con el grupo de placebo. CONCLUSIONES: los parches transdérmicos de lidocaína al 5% emergen como un complemento prometedor para el manejo del dolor postoperatorio en pacientes sometidos a artroscopía de rodilla. Su facilidad de aplicación, mínimos efectos secundarios y efectos ahorradores de opioides contribuyen a un enfoque analgésico multifacético. Este estudio destaca el potencial de los parches de lidocaína transdérmica para mejorar la experiencia postoperatoria general de los pacientes con artroscopía de rodilla, abogando por su consideración en la práctica clínica.

Impact of L-PRF on pain and healing outcomes in lower third molar surgery: a randomized split-mouth trial.

This study explored the effects of L-PRF on pain, soft tissue healing, periodontal condition, and post-extraction bone repair of mandibular third molars (3Ms). A randomized, prospective, triple-blind, split-mouth clinical trial was conducted with 34 volunteers. Eligible patients were randomly allocated into two treatments: G1 (without L-PRF), G2 (alveoli filled with L-PRF), in which the removal of bilateral 3Ms was performed at the same surgical time. Outcomes were assessed according to a visual analogue scale (pain), soft tissue scoring system (wound healing), periodontal probing of mandibular second molar. Bone repair was determined by volumetric analysis (ITK-SNAP software) and fractal analysis (ImageJ software). An intention-to-treat approach to Statistical analysis was used. L-PRF reduced pain in the 7-day postoperative follow-up (p = 0.019) and not only improved soft tissue healing after 1 month of follow-up (p = 0.021), but also probing depth (distal face) in 3 months postoperatively (p = 0.011). Significant alveolar reduction occurred in 3 months after surgery in both treatments (p < 0.05), however, this was more significant in G1 (p = 0.016). The fractal dimension showed no statistical differences. L-PRF improved postoperative clinical parameters of pain, soft tissue healing, and periodontal condition, suggesting that it has a beneficial effect on preserving the alveolar ridge and accelerating the initial repair process.

Pediatric Charcot-Marie-Tooth disease and peripheral nerve blocks: a retrospective cohort study of 25 patients.

PURPOSE: Charcot-Marie-Tooth (CMT) disease is an inherited neurologic disorder characterized by progressive peripheral neuropathies. The use of peripheral nerve blocks (PNB) in patients with CMT disease has been controversial because of concerns about exacerbating existing neurologic impairments and the "double hit" hypothesis. We aimed to assess the use of PNB in pediatric patients with CMT disease undergoing orthopedic surgery to address the limited data available in the literature on this topic. METHODS: In this retrospective cohort study, we included all pediatric patients with CMT disease scheduled for orthopedic surgery receiving PNB at our centre. All of the patients had preoperative neurologic exams and received one or more ultrasound-guided regional anesthesia techniques. Data extracted included details of anesthesia technique, surgical procedure, opioid consumption, and pain scores during the first three postoperative days. We also reviewed any complications such as neurologic deficits and local anesthetic toxicity. We used descriptive statistics to summarize the findings. RESULTS: We included 25 patients, 14 of whom (56%) presented with pre-existing neurologic deficits, primarily in the lower extremities. Postoperative assessments revealed no new neurologic impairments in 24/25 (96%) patients, with only one patient experiencing a nerve injury possibly related to the surgical procedure. Opioid consumption was low in the postanesthesia care unit and on the day of surgery. No additional complications were noted in the first 72 hr after surgery. CONCLUSION: Despite concerns, PNB showed favourable outcomes in a pediatric cohort with CMT disease, with low opioid consumption and pain scores and minimal complications during follow-up. These findings match previous reports of adult patients with CMT disease and suggest that the benefits of PNB may outweigh the perceived risks in pediatric patients with CMT disease.

RéSUMé: OBJECTIF: La maladie de Charcot-Marie-Tooth (CMT) est une maladie neurologique héréditaire caractérisée par des neuropathies périphériques progressives. L'utilisation de blocs nerveux périphériques (BNP) chez la patientèle atteinte de CMT est controversée en raison des inquiétudes concernant l'exacerbation des déficiences neurologiques existantes et de l'hypothèse d'une « double insulte ¼. Notre objectif était d'évaluer l'utilisation de BNP chez les patient·es pédiatriques atteint·es de CMT bénéficiant d'une chirurgie orthopédique afin de pallier les données limitées disponibles dans la littérature à ce sujet. MéTHODE: Dans cette étude de cohorte rétrospective, nous avons inclus tou·tes les patient·es pédiatriques atteint·es de CMT devant bénéficier d'une chirurgie orthopédique et recevant un BNP dans notre centre. Tou·tes ont bénéficié d'examens neurologiques préopératoires et ont reçu une ou plusieurs techniques d'anesthésie régionale échoguidées. Les données extraites comprenaient des détails sur la technique d'anesthésie, l'intervention chirurgicale, la consommation d'opioïdes et les scores de douleur au cours des trois premiers jours postopératoires. Nous avons également examiné toutes les complications telles que les déficits neurologiques et la toxicité des anesthésiques locaux. Nous avons utilisé des statistiques descriptives pour résumer les résultats. RéSULTATS: Nous avons inclus 25 patient·es, dont 14 (56 %) présentaient des déficits neurologiques préexistants, principalement dans les membres inférieurs. Les évaluations postopératoires n'ont révélé aucune nouvelle déficience neurologique chez 24 patient·es sur 25 (96 %), une seule personne ayant subi une lésion nerveuse possiblement liée à l'intervention chirurgicale. La consommation d'opioïdes était faible en salle de réveil et le jour de l'opération. Aucune complication supplémentaire n'a été notée dans les 72 premières heures après la chirurgie. CONCLUSION: Malgré les inquiétudes, le BNP a montré des résultats favorables dans une cohorte pédiatrique atteinte de CMT, avec une faible consommation d'opioïdes et des scores de douleur et des complications minimes pendant le suivi. Ces résultats correspondent à des comptes rendus antérieurs de patient·es adultes atteint·es de CMT et suggèrent que les avantages des BNP pourraient l'emporter sur les risques perçus chez la patientèle pédiatrique atteinte de CMT.

Effectiveness of Low-Level Laser Therapy in reducing postoperative pain after dental implant surgery: A randomized clinical trial.

BACKGROUND: A clinical trial was conducted to measure the effectiveness of a combined wavelength of 660 nm and 808 nm Low-Level Laser Therapy (LLLT) in reducing postoperative pain in partially and totally edentulous patients who underwent dental implant surgery. MATERIALS AND METHODS: The study included 20 blinded individuals divided in a randomized split-mouth fashion; the experimental group in one hemiarch and the control group in the other hemiarch. The experimental group received a total of 22.5 Joules (J) of LLLT divided into 5 points per implant immediately after surgery. The control group received a placebo treatment. At 24 h, 72 h, and 7 days, a blinded surveyor administered a pain questionnaire using a Numerical Rating Scale (NRS) combined with a Verbal Rating Scale (VRS) to assess pain onset after surgery, duration of the first pain episode, and pain evolution. Group data were analyzed with an ANOVA test for repeated measures and a paired t-test at defined time intervals. RESULTS: The experimental group showed a significant decrease in postoperative pain at 24 h and at 72 h for fully edentulous patients. There was a non-significant difference in the duration of the first pain episode. The mean pain levels decreased over time for both the experimental and control treatments, but only statistically significantly for the experimental group in the 24-72 h and 24 h to 7 days intervals. The same was true for the control group when comparing 24 and 72 h and between 24 h and 1 week. The time range between 72 h and 1 week showed no statistically significant differences. CONCLUSION: Within the limitations of this study, a single dose of 22.5 J LLLT per implant helps to decrease postoperative pain in dental implant surgery at 24 h for partially edentulous patients and at 24 and 72 h for fully edentulous patients.

A combined treatment for self-traumatic chronic skin lesions associated with post-surgical neuropathic pain in a domestic cat: a pharmacological and cold atmospheric plasma approach.

Cold atmospheric plasma (CAP) has been employed as a therapy against both acute and chronic skin lesions, contaminated or not, and has effects on angiogenesis and reepithelialization promoting healing. In this context, the present study aimed to evaluate the effects of a CAP jet associated with pharmacological treatment described by the 2015 AAHA/AAFP pain management guidelines and the 2022 WSAVA guidelines for the recognition, assessment, and treatment of pain, on the healing of chronic skin lesions caused by a pruritic reaction resulting from post-surgical neuropathic pain. To this end, a single CAP application was performed on a feline patient with a 6 months old recurrent contaminated cervical skin lesions along with administration of ketamine (10 µg/kg/min) following the prescription of prednisone (1 mg/kg, SID, 6 days), gabapentin (8 mg/kg, BID, 60 days) and amitriptyline (0.5 mg /kg, SID, 60 days). A single application of plasma associated with an NMDA antagonist, anti-inflammatory steroid, tricyclic antidepressant and gabapentinoid thus provided a significant improvement in the macroscopic appearance of the lesion within 10 days, and the owner reported the cessation of intense itching within the first four hours after treatment and a consequent improvement in the animal's quality of life. The medical treatment was finished almost a year since the writing of this paper, without clinical or reported recurrent signs of the condition. Therefore, we observed that single dose CAP application associated with ketamine, gabapentin, amitriptyline and prednisone leads to significant healing of chronically infected skin lesions resulting from post-surgical neuropathic pain.

The effect of intracanal cryotherapy with and without foraminal enlargement on pain prevention after endodontic treatment: a randomized clinical trial.

This randomized clinical trial aims to evaluate cryotherapy as a therapeutic option for pain prevention after endodontic treatment with and without foraminal enlargement, in patients with asymptomatic apical periodontitis.120 teeth of patients with preoperative Visual Analogue Scale score indicating zero were treated. Specimens were randomly allocated into 4 groups: Control, Cryotherapy (ICT), Foraminal Enlargement (FE), and Cryotherapy and Foraminal Enlargement (ICT + FE). Working length was determined with an Electronic Apex Locator (EAL). Cryotherapy groups passed through a final irrigation protocol using 20 ml (2.5 â„ƒ) of cold saline solution delivered at working length for 5 min. In FE groups a #40 K-file was used up to the 0.0 mark on the EAL display. Obturation was performed and postoperative pain was checked at 6, 12, 24, 48, and 72 h and 7 days after endodontic treatment.All experimental groups showed an increase in the level of postoperative pain, which started to decrease after 12 h. Foraminal enlargement caused a statistically significant increase in postoperativepain compared to ICT and control groups within the first 6 h (p < 0.05). Cryotherapy did not influence postoperative pain, regardless of whether or not foraminal enlargement was performed.

Cordotomy for pain control and opioid reduction in cancer patients: A cancer center 11-year experience.

BACKGROUND: Percutaneous lateral cervical cordotomy (PLCC) is a treatment option for predominantly nociceptive pain of oncological origin that is refractory to conservative methods, with unilateral distribution, particularly in the lower trunk or lower limbs of patients with a life expectancy of less than one year. OBJECTIVE: The aim of this study was to assess the analgesic efficacy and opioid utilization alteration in patients undergoing PLCC. METHODS: We retrospectively collected data from patients undergoing PLCC between 2011 and 2021 at the AC Camargo Cancer Center in São Paulo, Brazil. RESULTS: Sixty-three patients and their respective surgical outcomes were analyzed. The mean preoperative pain intensity, as assessed by the mean numerical rating scale (NRS), was 8.4 (range: 4-10), while postoperatively, it decreased to 0.78 (range: 0-8). Lower postoperative NRS scores were observed for pain in the lower limbs and abdomen compared to the lower thorax. The mean preoperative oral morphine equivalent (OME) consumption was 231.0 mg (range: 30.0-1015.2). At 30 days postoperative, the mean consumption of OME was 120.2 mg (range: 0.0-705.0). Twelve months after surgery, the average consumption of OME was 98.3 mg (range: 0.0-396.0). CONCLUSION: PLCC is a valuable therapeutic intervention for patients experiencing cancer pain that is unresponsive to conservative treatments. The anticipated analgesic outcomes are generally favorable, particularly in cases where the pain is localized unilaterally in the abdomen or lower body segments.

Postoperative pain in oncological patients subjected to nonsurgical root canal treatment: a prospective case-control study.

OBJECTIVES: The purpose of this prospective study was to evaluate the incidence and intensity of postoperative pain in oncological patients with infected teeth subjected to nonsurgical root canal treatment or retreatment. METHODS: Teeth with apical periodontitis from healthy control patients and oncological patients (n = 70 per group) were root canal treated/retreated and evaluated for the development of postoperative pain. Patients from the two groups were matched for tooth type, gender, clinical manifestation of apical periodontitis, and intervention type. A visual analogue scale (VSA) was used to evaluate the incidence of postoperative pain at 24 h, 72 h, 7d, and 15d after chemomechanical procedures. Data were statistically analyzed for the incidence and intensity of postoperative pain in the two groups. RESULTS: Preoperative pain occurred in 10% of the individuals and in all these cases pain showed a reduction in intensity or was absent after endodontic intervention at 24-h evaluation. The overall incidence of postoperative pain at 24 h was 14% in oncology patients and 30% in controls (p = 0.03). At 72 h, the respective corresponding figures were 4% and 8.5% (p > 0.05). At 7 and 15 days, all patients were asymptomatic, irrespective of the group. CONCLUSIONS: No significant differences in postoperative pain were found between control and oncological patients. The low incidence of postoperative pain observed in both groups supports the routine use of nonsurgical root canal treatment/retreatment as valid options in oncological patients. CLINICAL RELEVANCE: Oncological patients had no increased risk of postoperative pain in comparison with control patients.

Efficacy of preoperative and postoperative medications in reducing pain after non-surgical root canal treatment: an umbrella review.

OBJECTIVE: This study analyzed, using an umbrella review, existing systematic reviews on medications to prevent and control postoperative endodontic pain to guide professionals in choosing the most effective drug. MATERIALS AND METHODS: An electronic search in the PubMed (MEDLINE), LILACS, SciELO, EMBASE, Scopus, Web of Science, Cochrane Reviews, and Data Archiving and Networked Services (DANS) databases retrieved 17 systematic reviews. The study included only systematic reviews of clinical trials with or without meta-analyses evaluating effectiveness of medications in reducing pain after non-surgical endodontic treatment. RESULTS: The evidence showed that steroidal and non-steroidal anti-inflammatory drugs and opioids effectively controlled pain within six to 24 h. CONCLUSIONS: Dexamethasone, prednisolone, paracetamol, and mainly ibuprofen provided higher postoperative pain relief. The quality of evidence of the reviews ranged from very low to high, and the risk of bias from low to high, suggesting the need for well-designed clinical trials to provide confirmatory evidence. CLINICAL RELEVANCE: This review emphasizes the efficacy of developing protocols for pain control after endodontic therapy.

Association between preoperative fasting time and clinical outcomes in surgical patients in a private general hospital.

PURPOSE: Surgical patients are routinely subjected to long periods of fasting, a practice that can exacerbate the metabolic response to trauma and impair postoperative recovery. The aim of this study was to evaluate the association between preoperative fasting time and clinical outcomes in surgical patients. METHODS: An observational, prospective study with a non-probabilistic sample that included patients of both sexes, aged over 18, undergoing elective surgeries. Data were extracted from electronic medical records, and a questionnaire was applied in 48 hours after surgery. Variables related to postoperative discomfort were assessed using an 11-point numeric rating scale. RESULTS: The sample consisted of 372 patients, and the duration of the surgical event ranged from 30-680 minutes. The incidence of nausea (26.34%) was twice that of vomiting (13.17%) and showed an association with the surgical procedure's size (p = 0.018). A statistically significant difference was observed only between pain intensity and preoperative fasting times for liquids (p = 0.007) and postoperative fasting time (p = 0.08). The occurrence of postoperative complications showed no association with preoperative fasting time (p = 0.850). CONCLUSIONS: Although no association was observed between preoperative fasting time and surgical complications, it is noteworthy that both recommended and actual fasting time exceeded the proposed on clinical guidelines.

Modified thoracoabdominal nerve block via perichondral approach: an alternative for perioperative pain management in laparoscopic cholecystectomy in a middle-income country.

BACKGROUND: Laparoscopic cholecystectomy is known for its minimally invasive nature, but postoperative pain management remains challenging. Despite the enhanced recovery after surgery (ERAS) protocol, regional analgesic techniques like modified perichondral approach to thoracoabdominal nerve block (M-TAPA) show promise. Our retrospective study evaluates M-TAPA's efficacy in postoperative pain control for laparoscopic cholecystectomy in a middle-income country. METHODS: This was a retrospective case-control study of laparoscopic cholecystectomy patients at Hospital General de Mexico in which patients were allocated to the M-TAPA or control group. The data included demographic information, intraoperative variables, and postoperative pain scores. M-TAPA blocks were administered presurgery. OUTCOMES: opioid consumption, pain intensity, adverse effects, and time to rescue analgesia. Analysis of variance (ANOVA) compared total opioid consumption between groups, while Student's t test compared pain intensity and time until the first request for rescue analgesia. RESULTS: Among the 56 patients, those in the M-TAPA group had longer surgical and anesthetic times (p < 0.001), higher ASA 3 scores (25% vs. 3.12%, p = 0.010), and reduced opioid consumption (p < 0.001). The M-TAPA group exhibited lower postoperative pain scores (p < 0.001), a lower need for rescue analgesia (p = 0.010), and a lower incidence of nausea/vomiting (p = 0.010). CONCLUSION: Bilateral M-TAPA offers effective postoperative pain control after laparoscopic cholecystectomy, especially in middle-income countries, by reducing opioid use and enhancing recovery.

Exploring the relationship between anxiety, patient characteristics and pain outcomes in oral surgery under local anesthesia: The measurement problem.

BACKGROUND: Anxiety during oral surgery can impact patient homeostasis, increase the difficulty of the procedure and create additional stress for the surgeon. Furthermore, it has been associated with more intense and prolonged pain during and after dental treatment. OBJECTIVES: The aim of the study is to evaluate the relationship between anxiety, patient characteristics and pain outcomes in oral surgery, as well as to verify the impact of anxiety on patient's perception of pain during and after oral surgery. MATERIAL AND METHODS: This is a prospective observational study. Several variables were evaluated during the course of the oral surgery. Anxiety levels were assessed using the State-Trait Anxiety Inventory (STAI), Corah's Dental Anxiety Scale (DAS), the Interval Scale of Anxiety Response (ISAR), and Patient SelfRated Anxiety (PAnx) during the procedure. RESULTS: General anxiety measures (STAI) were not associated with specific dental anxiety or external observations of anxiety. Anxiety levels varied according to gender and body mass index (BMI), and were correlated with increased heart rate (HR) (with variability among assessment tools). Odontectomy, ostectomy and an increased volume of anesthesia were associated with higher anxiety levels (with variability among the assessment tools). There was a correlation between pain and anxiety, with anxiety contributing to approx. 12% of the variability in postoperative pain. CONCLUSIONS: Dental anxiety is a complex, multidimensional mental phenomenon characterized by high variability due to the influence of several dynamic factors.

Suture versus tacks in minimally invasive transabdominal preperitoneal inguinal repair: a meta-analysis of randomized controlled trials.

INTRODUCTION: There is uncertainty regarding the method of mesh fixation and peritoneal closure during transabdominal preperitoneal (TAPP) repair for inguinal hernias, with no definitive guidelines to guide surgeon choice. METHODS: MEDLINE, Cochrane, Central Register of Clinical Trials, and Web of Science were searched for RCTs published until November 2023. Risk ratios (RRs) and mean differences (MD) with 95% confidence intervals (CIs) were pooled with a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the Cochran Q test and I2 statistics, with p values inferior to 0.10 and I2 > 25% considered significant. Statistical analyses were conducted using Review Manager version 5.4 and RStudio version 4.1.2 (R Foundation for Statistical Computing). RESULTS: Eight randomized controlled trials (RCTs) were included, comprising 624 patients, of whom 309 (49.5%) patients were submitted to TAPP with the use of tacks, and 315 (50.5%) received suture fixation. The use of tacker fixation was associated with a significant increase in postoperative pain at 24 h (MD 0.79 [VAS score]; 95% CI 0.38 to 1.19; p < 0.0002; I2 = 87%) and one week (MD 0.42 [VAS score]; 95% CI 0.05 to 0.79; p < 0.03, I2 = 84%). The use of tacks was associated with shorter operative time (MD-25.80 [min]; 95% - 34.31- - 17.28; P < 0.00001; I2 = 94%). No significant differences were found in overall complications, chronic pain, seromas, hematomas, and urinary retention rates. CONCLUSION: In patients who underwent TAPP hernia repair, tacks are associated with decreased operative time but increased postoperative pain at 24 h and one week.

Comparison of postoperative chronic inguinal pain between the lichtenstein and laparoscopic techniques in the treatment of inguinal hernia: a systematic review and meta-analysis.

PURPOSE: Currently, inguinal hernias are highly prevalent in the Brazilian population, accounting for 75% of all abdominal wall hernias. The recommended treatment to correct them is inguinal herniorrhaphy, which can be performed through open surgery, mainly using the Lichtenstein technique, or laparoscopically, primarily through Transabdominal Preperitoneal Repair (TAPP) or Total Extraperitoneal Repair (TEP) approaches. Like any surgery, these procedures have post-operative complications, with pain being the most common and debilitating. Currently, in European and Brazilian guidelines, the open Lichtenstein and endoscopic inguinal hernia techniques are recommended as best evidence-based options for repair of a primary unilateral hernia providing the surgeon is sufficiently experienced in the specific procedure. In that matter, the surgeon should make a choice based on assessment of the benefits and risks of performing each of them, and practice shared making decision with it patient. Therefore, the objective of this review was to assess the incidence of chronic postoperative pain by comparing the aforementioned surgical approaches to evaluate which procedure causes less disability to the patient. METHODS: The search conducted until May 2024 was performed on Medline (PubMed), Cochrane (CENTRAL), and Lilacs databases. The selection was limited to randomized clinical trials, nonrandomized clinical trials and cohort studies comparing TAPP or TEP to LC, evaluating the incidence of chronic postoperative pain published between 2017 and 2023. Evidence certainty was assessed using the GRADE Pro tool, and bias risk was evaluated with the RoB 2.0 tool and ROBINS I tool. Thirteen studies were included.  RESULTS: The meta-analysis showed a significant difference between the groups in both techniques, favoring the laparoscopic approach, which had a lower occurrence of postoperative inguinodynia with a relative risk of 0.49 (95% CI = 0.32, 0.75; I2 = 66% (P = 0.001); Z = 3.28 (P = 0.001) with low certainty of evidence. CONCLUSION: The presence of chronic postoperative pain was lower in laparoscopic TEP/TAPP techniques when compared to the open Lichtenstein technique, meaning that the former can bring more benefits to patients who requires inguinal herniorrhaphy. Nevertheless, further randomized clinical trials are needed to optimize the analysis, minimizing the bias.

Preoperative Acetaminophen For Microsuspension Laryngoscopy Reduces Postoperative Opioid Use.

OBJECTIVES: The opioid crisis has prompted consideration of analgesic prescriptions. This study explored the value of preoperative acetaminophen for pain control following microsuspension laryngoscopy (MSL) and compared the results with a previous study of pain and opioid use following MSL (Tsang et al.). METHODS: A prospective open-label clinical trial was conducted in patients undergoing MSL. All patients were administered preoperative acetaminophen. Short-form McGill Pain Questionnaire (SF-MPQ), pain visual analogue scale (VAS), and present pain intensity (PPI) scores were collected preoperatively and on postoperative days (PODs) 1, 3, 7, and 14. Statistical analysis identified variables associated with opioid use or increased pain scores, and compared outcomes with Tsang et al. RESULTS: Eighty-nine patients were included (mean age 52.8 ± 17.3 years, 40 males). All patients received preoperative 1 g acetaminophen (77 (86.5%) orally) with no adverse effects. On POD1, opioid usage was 10%. Median [IQR] pain scores were 5 [2-11], 21 [12.3-56.8], and 3 [2-3.3] on SF-MPQ, VAS, and PPI, respectively. Post-Anesthesia Care Unit (PACU) opioid requirements significantly correlated with POD1 opioid consumption (τb = 0.214; p ≤ 0.05), and significant associations with PACU opioid administration were found for total anesthesia time (OR (95%CI) = 1.271 (1.043-1.548), p = 0.017) and total laryngoscope suspension time (OR (95%CI) = 0.791 (0.651-0.962, p = 0.019)). This cohort demonstrated reduced opioid usage on POD1 compared with Tsang et al (23%). CONCLUSIONS: Preoperative acetaminophen is a safe intervention, resulting in decreased postoperative opioid use following MSL. Anesthesia time correlated with need for postoperative opioids.
