Clinical and thermographic evaluation after lower third molar extractions and the application of different photobiomodulation protocols: double-blind randomised clinical trial.

OBJECTIVES: to compare the parameters of pain, oedema, temperature, and soft tissue closure in dental sockets that received two different photobiomodulation (PBM) protocols following extractions. MATERIALS AND METHODS: Thirty-one participants had their teeth 38 and 48 extracted. Subsequently, one of the dental sockets received PBM at a wavelength (WL) of 808 nanometers (808 group- nm) and the other dental socket received the PBM at WLs of 808 nm and 660 nm, simultaneously (808 + 660 group). The PBM was applied immediately after the surgical procedure and on the 3rd and 7th days. RESULTS: The mean of Visual Analogue Scale (VAS) values for pain were 1.45 for the 3rd day and 0.52 for the 7th day in the 808 + 660 and 808 group, respectively. The mean the pogonion-tragus measurement, used to assess facial oedema on the 3rd day, was 15.38 cm (range 13.5-17.5) in the 808 + 660 group and 15.48 cm (range 14.0-17.5) in the 808 group. The mean facial temperatures in the 808 + 660 group were 34.9 degrees Celsius (ºC) (range 33.5-36.4) on the 3rd day and 35 ºC (range 33.4-36.4) on the 7th day. In the 808 group, the mean temperatures were 34.9 ºC (range 33.9-36.2) on the 3rd day and 34.9 ºC (33.7-36.2) on the 7th day. Regarding the dimensions of the dental socket, the mean were similar for both groups. Significant differences between the groups were only observed in the pain parameter and only on the 7th day, being greater for the 808 + 660 group (p = 0.031). CONCLUSIONS: The association of the 660 nm with 808 nm, and the increase in energy did not showed more benefits in pain reduction oedema, or acceleration of the closure of the soft tissues of the dental sockets of lower third molars, in the protocols used here. CLINICAL RELEVANCE: There is no need to combine lasers at wavelengths of 660 and 808 nm to reduce oedema, pain and repair of soft tissues after extraction of lower third molars. CLINICAL TRIAL REGISTRATION: This trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with the following code: RBR-66pyrh8, on 29th December, 2022.

Shoulder pain management strategies and early functional outcome after arthroscopic rotator cuff tear repair. A randomized controlled study.

BACKGROUND: The management of acute postoperative pain after rotator cuff surgery can be challenging. To our knowledge, there are no data available in the literature correlating satisfactory pain control with improvement in terms of function. The purposes of the present study were to evaluate: 1) pain pattern after arthroscopic rotator cuff repair in patients operated with two different techniques (transosseous vs transosseous equivalent); 2) safety/efficacy of three different pharmacological pain control strategies; 3) possible relationship between a correct shoulder pain management protocol in the early post-operative period and patients' functional improvement. METHODS: 114 patients underwent rotator cuff tear repair, either with a Transosseus or a Transosseus equivalent technique. 62 (54%) were male and 52 (46%) were female. The average age was 59 ± 9 years. They were randomly assigned into three different pain management protocols: Paracetamol as needed (max 3 tablets/day) for 1 week (Protocol A), Paracetamol + Codein 1 tablet three times per day for 7 days (Protocol B), or Paracetamol + Ibuprofen 1 tablet two times per day for 7 days (Protocol C). Immediate passive mobilization of the operated shoulder was allowed. VAS and Passive Flexion values were recorded at 7 (T1), 15 (T2) and 30 (T3) days post-surgery. DASH values were recorded at 90 days post-surgery. All patients were asked to register any kind of signs/symptoms that may appear during drug assumption according to each pain management protocols. RESULTS: All the pain management protocols administered were well tolerated by all the study population, and no adverse signs/symptoms were highlighted during drug assumption. Pain pattern: in both surgical techniques, patients within Protocol A were associated with worst results in terms of mean VAS at each time point examined when compared to Protocol B and C (p < 0,05). In patients within Protocol A, no statistically significant differences were found at each point time examined comparing the two surgical techniques, with the exception of T2, where the TO was associated with an higher VAS value than TOE (p < 0.05). No differences were highlighted in Protocol B and C when comparing the values between two surgical techniques. ROM: in both surgical techniques, patients within Protocol A were associated with worst results in terms of mean PROM at each time point examined when compared to Protocol B and C (p < 0,05). In the TO group, patients within Protocol B had better PROM values at T1 (p < 0,05) and T2 (p < 0,05) compared to Protocol C, but no differences were highlighted at T3. In the TOE group, no statistically significant differences were found between patients within Protocol B and C at each time point examined. DASH: In the TO group, no statistically significant differences were found regarding the DASH values comparing Protocol B vs Protocol C, but they were highlighted comparing the values between Protocol A and Protocol B (p < 0,05), and between Protocol A and Protocol C (p < 0,05). Similar results were recorded in the TOE group. CONCLUSION: Post-operative pain is influenced by the surgical technique used being transosseous more painful in the first 15 days after surgery. Oral anti-inflammatory drugs are a feasible strategy to appropriately control post-operative pain. An association between Paracetamol and either Codein or Ibuprofen can lead to better outcomes in terms of VAS reduction and early recovery of passive ROM.

Analgesic efficacy of local infiltration anaesthesia versus femoral nerve block in alleviating postoperative wound pain following total knee arthroplasty: A systematic review and meta-analysis.

Total knee arthroplasty (TKA) often involves significant postoperative pain, necessitating effective analgesia. This meta-analysis compares the analgesic efficacy of local infiltration anaesthesia (LIA) and femoral nerve block (FNB) in managing postoperative wound pain following TKA. Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this meta-analysis was structured around the PICO framework, assessing studies that directly compared LIA and FNB in TKA patients. A comprehensive search across PubMed, Embase, Web of Science and the Cochrane Library was conducted without time restrictions. Studies were included based on specific criteria such as participant demographics, study design and outcomes like pain scores and opioid consumption. Quality assessment utilized the Cochrane Collaboration's risk of bias tool. The statistical approach was determined based on heterogeneity, with the choice of fixed- or random-effects models guided by the I2 statistic. Sensitivity analysis and evaluation of publication bias using funnel plots and Egger's linear regression test were also conducted. From an initial pool of 1275 articles, eight studies met the inclusion criteria. These studies conducted in various countries from 2007 to 2016. The meta-analysis showed no significant difference in resting and movement-related Visual Analogue Scale scores post-TKA between the LIA and FNB groups. However, LIA was associated with significantly lower opioid consumption. The quality assessment revealed a low risk of bias in most studies, and the sensitivity analysis confirmed the stability of these findings. There was no significant publication bias detected. Both LIA and FNB are effective in controlling postoperative pain in TKA patients, but LIA offers the advantage of lower opioid consumption. Its simplicity, cost-effectiveness and opioid-sparing nature make LIA the recommended choice for postoperative analgesia in knee replacement surgeries.

Clinical Effect of Ultrasound-Guided Adductor Block on Postoperative Analgesia After Total Knee Replacement.

Objective: To explore the clinical effects of ultrasound-guided adductor block (UGAB) on postoperative analgesia after total knee replacement. Methods: From March 2022 to June 2022, 60 patients in the First Affiliated Hospital of Chongqing Medical University were included. They were divided into control (n = 30) and ultrasonic groups (n = 30). They all received total knee arthroplasty. Before total knee arthroplasty, patients in the control and ultrasonic groups underwent general anesthesia and UGAB, respectively. Visual Analogue Scale (VAS) was used to assess the pain. The time of the first straight leg elevation and the first landing time were recorded. Knee joint function was evaluated. Information about the dosage of tramadol intramuscular injection and the number of times patient-controlled analgesia pump pressing was collected. The serum levels of interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) were detected. Results: Compared with the control group, UGAB increased the rate of muscle contraction and relaxation and total and relaxation after total knee replacement in the ultrasonic group (P < .05). UGAB reduced VAS scores of pain during passive activity after operation (P < .05). UGAB also facilitated the first straight leg lifting time after the operation and the time of the first landing after the operation (P < .05). Meanwhile, UGAB reduced the dose of tramadol and press times of the self-control analgesia pump after operation (P < 0.05). UGAB also suppressed postoperative IL-6 and hs-CRP levels and increased postoperative joint range of motion (P < .05). Conclusion: UGAB promotes early recovery of knee function with high safety in patients undergoing total knee replacement, with reduced postoperative pain and inflammatory reaction.

Effectiveness of acupuncture for postoperative gastrointestinal recovery in patients undergoing thoracoscopic surgery: a prospective randomized controlled study.

BACKGROUND: Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications among patients who have undergone thoracic surgery. Acupuncture has long been used in traditional Chinese medicine to treat gastrointestinal diseases and has shown benefit as an alternative therapy for the management of digestive ailments. This study aimed to explore the therapeutic effectiveness of acupuncture as a means to aid postoperative recovery of gastrointestinal function in patients undergoing thoracoscopic surgery. METHODS: In total, 112 patients aged 18-70 years undergoing thoracoscopic surgery between 15 June 2022 and 30 August 2022 were randomized into two groups. Patients in the acupuncture group (AG) first received acupuncture treatment 4 h after surgery, and treatment was repeated at 24 and 48 h. Patients in the control group (CG) did not receive any acupuncture treatment. Both groups received the same anesthetic protocol. Ultrasound-guided thoracic paravertebral block (TPVB) was performed in the paravertebral spaces between T4 and T5 with administration of 20 mL of 0.33% ropivacaine. All patients received patient-controlled intravenous analgesia (PCIA) after surgery. RESULTS: Median time to first flatus [interquartile range] in the AG was significantly less than in the CG (23.25 [18.13, 29.75] vs 30.75 [24.13, 45.38] h, p < 0.001). Time to first fluid intake after surgery was significantly less in the AG, as compared with the CG (4 [3, 7] vs 6.5 [4.13, 10.75] h, p = 0.003). Static pain, measured by visual analog scale (VAS) score, was significantly different on the third day after surgery (p = 0.018). Dynamic pain VAS scores were lower in the AG versus CG on the first three postoperative days (p = 0.014, 0.003 and 0.041, respectively). CONCLUSION: Addition of acupuncture appeared to improve recovery of postoperative gastrointestinal function and alleviate posteoperative pain in patients undergoing thoracoscopic surgery. Acupuncture may represent a feasible strategy for the prevention of PGD occurrence. TRIAL REGISTRATION NUMBER: ChiCTR2200060888 (Chinese Clinical Trial Registry).

Is enhanced recovery after surgery essential?

BACKGROUND: The enhanced recovery after surgery (ERAS) method is designed for the patient to recover quickly, have less pain and have a more comfortable period after the surgery; that includes preoperative, intra and postoperative processes. ERAS has been started to be applied in cesarean section surgeries as the patients need to recover quickly. In the literature, there is no study about the results of ERAS in cesarean section about pain scores and complications. OBJECTIVES: It is aimed to compare the results of cesarean section patients using the ERAS method completely in patients who have had cesarean section without meeting some of the postoperative conditions of the ERAS criteria. STUDY DESIGN: It is a prospective study designed as postoperative metoclopramide, enema and routine opioids in group 1, enema and metoclopramide in group 2, metoclopramide only in group 3 and nothing in group 4. Postoperative pain scoring was done by using visual analog scale (VAS). Analysis of variance tests and t tests were used for results. RESULTS: There was no difference between groups according to age, parity, and birth weight. As a result, although there was no difference between the groups in terms of discharge time and complications, the VAS score used in pain scoring was found to be significantly lower in group 3 compared to the other groups (p: 0.000). Only metoclopramide group (group 3) had lowest VAS score. CONCLUSION: It has been revealed that the ERAS procedure does not need to be so detailed in the postoperative period, and the addition of metoclopramide may be sufficient. Since pain can be a subjective factor, other randomized studies are needed in terms of other criteria.

Effectiveness of low power laser in reducing postoperative signs and symptoms after third molar surgery: a triple-blind clinical trial.

The objective of this research was to evaluate the effectiveness of using LPL (Low power laser) to reduce pain, edema, and trismus after impacted lower third molar extraction. A split-mouth randomized triple-blind clinical trial was conducted at the Federal University of Ceará. For inclusion criteria, it was necessary that the patient presented a clear indication for removal of both lower third molars, in addition to both molars being in similar positions. The third molars (38 and 48) were randomly allocated to the test group that received the LPL application protocol, and to the placebo group that received a simulation of the protocol, making a total sample of 44 surgeries. Patients in the test group used an average of 50% of the amount of analgesics that was used by the placebo group, however, there was a statistically significant difference only on days four and five. Regarding trismus, the test group presented wide mouth openings, both at 48 hours and at 7 days after surgery compared to the placebo group, but without a statistically significant difference. For edema, we noted an equilibrium between the test group and the placebo group, but no measurement obtained a statistically significant difference. The use of LPL presented better pain and trismus indicators after complex extractions. The use of LPL is thus indicated as a complementary therapy to reduce postoperative discomfort caused by complex tooth extractions.

The role of oral bromelain on "bad outcome" in mandibular third molar surgery. A split-mouth comparative study.

AIM: to evaluate evidence of therapeutic efficacy of 9.6 g bromelain after mandibular third molar surgery. MATERIAL OF STUDY: This study is a prospective split-mouth clinical study of 49 patients, 22 male and 27 female, mean age 25.4 years old (range from 18-30 years). Each patient received two interventions in two different dates with 1 month of distance: the first third molar to be removed was chosen with a coin; at the second date of surgery bromelain was administered, one packet (9.6 g) every 12 hours for seven days. The evaluation of postoperative facial swelling was measured through specific measurements at every date on the side of the surgery. RESULTS: A total of 98 third molars were extracted. No major complications occurred after the surgery. Regarding the comparison between the results of the measurements made after surgery with the use of bromelain a statistically significant difference (p = 0,0078) resulted between the interventions that provided the use of bromelain (10.56 average value) and interventions in which bromelain was not provided (12.59 average value). CONCLUSIONS: The usefulness of this clinical trial is to provide a bromelain dosage and reduce the bad outcome after mandibular third molar surgery. KEY WORDS: Bromelain, Swelling, Third Molar.

Analgesic effects of perioperative acupuncture methods: A narrative review.

Postoperative pain occurs immediately after surgery. The most common perioperative analgesic methods are nerve block, patient-controlled intravenous analgesia, and patient-controlled epidural analgesia. However, overuse of opioid analgesics can cause many adverse reactions including excessive sedation, respiratory inhibition, postoperative nausea, and vomiting. In recent years, many clinical trials have shown that perioperative acupuncture has unique advantages in patients. Perioperative acupuncture can relieve intraoperative pain, improve postoperative pain management, reduce postoperative nausea and vomiting, and shorten the length of hospital stay. This study aimed to confirm the analgesic effect of perioperative acupuncture by reviewing studies on the different methods of perioperative acupuncture and their analgesic effects. The cited literature was searched in English and Chinese from PubMed, China National Knowledge Infrastructure, and Wanfang data, using the following keywords: "perioperative pain," "acupuncture," "electroacupuncture," and "perioperative analgesia." Studies published from 2005 to 2023 were included. All retrieved papers were read in detail. Perioperative acupuncture has benefits in reducing postoperative pain and opioid need. Although analgesic drugs are still the primary means of postoperative pain control, acupuncture provides a safe analgesic supplement or alternative. This review aimed to assist practitioners in choosing appropriate perioperative acupuncture methods by summarizing the recent literature on the role of different acupuncture approaches for perioperative pain management.

The impact of intraoperative N-acetylcysteine on opioid consumption following spine surgery: a randomized pilot trial.

Aim: N-acetylcysteine (NAC) decreases inflammation and could augment perioperative analgesia. Materials & methods: This prospective pilot trial examined postoperative opioid consumption at 12 h following intraoperative NAC. In phase I, 20 adults scheduled for posterior spine surgery were randomized to NAC (0, 50, 100 and 150 mg/kg) to determine the optimal dose. In phase II, 30 patients were randomized to placebo or NAC (150 mg/kg). Opioid consumption, pain ratings and time to opioid rescue were recorded. Results: Postoperative opioid consumption was reduced in the NAC group 19.3% at 12 h and 20% at 18 and 36 h. Opioid consumption was reduced 22-24% in the NAC group at all times after adjusting for intraoperative opioid administration. NAC subjects reported lower pain scores relative to placebo. Conclusion: Subjects randomized to NAC consumed less postoperative opioids and reported less pain versus placebo. Larger randomized controlled trials are needed to further evaluate NAC for analgesia. Clinical Trial Registration: NCT04562597 (ClinicalTrials.gov).

N-acetylcysteine (NAC) is a powerful anti-inflammatory drug used to treat some types of poisoning. It could help pain for patients after surgery. This study looked at how much pain medicine patients needed after back surgery when they received NAC or no drug (placebo). In the first 20 patients, people randomly received placebo or a small, medium or large dose of NAC (0, 50, 100, and 150 mg/kg) with five patients in each group. Since there were only a small number of patients, it was difficult to see any definite differences, and the next 30 patient patients randomly received placebo or the large dose of NAC (150 mg/kg). Patients that were given NAC received 16­22% less opioids in the first 2 days after surgery compared with those that were given placebo. NAC patients also took longer to request pain medications after surgery and reported lower pain scores in the first 2 days after surgery relative to placebo.

[Electrophysiological appropriateness technique based on TCM meridian theory for postoperative pain after urethral reconstruction: A real-world study].

OBJECTIVE: To investigate the clinical efficacy of electrophysiological appropriateness technique (EAT) therapy based on the traditional Chinese medicine (TCM) meridian theory in managing postoperative pain after urethral reconstruction surgery. METHODS: Using the real-world study approach, we enrolled 61 male patients undergoing urethral reconstruction and divided them into a control group (n = 30) and an observation group (n = 31), the former receiving patient-controlled intravenous analgesia (PCIA), while the latter PCIA plus EAT at 4 pairs of acupoints (Hegu, Neiguan, Zusanli and Sanyinjiao bilaterally) and the Ashi point, with 100 mg tramadol hydrochloride given orally as remedial analgesia in both groups in case of postoperative Visual Analogue Scale (VAS) score ≥4. We compared the VAS scores at 4, 12, 24 and 48 hours postoperatively, the dose of cumulative fentanyl used at 48 hours, the number of cases needing remedial analgesia, the time to first flatus and the incidence of adverse reactions between the two groups of patients. RESULTS: The VAS scores were markedly lower in the observation than in the control group at 4, 12, 24 and 48 hours after surgery (P < 0.05), with statistically significant differences in time-dependent effect and interactive effect (P < 0.05). Significant reduction was observed in the doses of cumulative fentanyl (P < 0.05) and remedial tramadol analgesia (P < 0.05), time to first flatus (P < 0.05), and incidence of adverse reactions (P < 0.05) in the observation group in comparison with the controls. CONCLUSION: Electrophysiological therapy based on the TCM meridian theory can safely and effectively alleviate postoperative pain after urethral reconstruction, reduce opioid consumption, and decrease adverse events.

Persistent socket pain in a dog after the enucleation of the eye and its clinical management.

Persistent socket pain is a condition described in humans after enucleation of the eye. This report aims at describing this condition in dogs. A 10-year-old male-neutered crossbreed was presented to the referral veterinary surgeon for enucleation of the right ocular globe. Anaesthesia and surgery were uneventful although during the postoperative period the dog was reluctant to open the mouth and to be explored by the referral veteterinary surgeon. Despite treatment with meloxicam, paracetamol and tramadol, no improvements were observed. Ten weeks after surgery, the dog was referred to the Dick White referrals for further investigations. Ophthalmic examination was normal, though palpation of the wound triggered an avoidance response. Magnetic resonance imaging showed changes compatible with orbital cellulitis. The area of interest was evaluated with the use of the mechanical Von Frey filaments. A response, characterised by sudden turning of the head and attempts to withdraw it, was evoked with filament 4.93 (8.0 g) during stimulation of the periorbital area. After induction of anaesthesia, an ultrasound-guided injection containing levobupivacaine 0.5% and methylprednisolone was performed within the retrobulbar area. Three hours after recovery from anaesthesia, no discomfort was observed during palpation of the area. Re-evaluation was performed with the Von Frey filaments; no response could be evoked during testing with all 20 filaments (from 2.36 to 6.65) applied on either side of the face. The patient was discharged with a course of gabapentin and, 3 weeks after the intervention, the dog showed no clinical signs of pain. Persistent socket pain is an unpleasant sensation at the level of the enucleated orbit, and it should be regarded as a challenging condition to diagnose and treat. The MRI findings appeared to be essential to select the most appropriate interventional treatment. The injection of local anaesthetic and steroid into the retrobulbar space was useful for both confirming the diagnosis and treating pain by reducing the peripheral signalling and decreasing the residual inflammation.

Trends of opioid prescription in cancer patients utilizing telemedicine: a retrospective study.

Aim: Prescribing patterns among healthcare practitioners remain a recurring theme of interest in the opioid crisis. This study aims to provide insight on opioid prescribing patterns for cancer pain in telemedicine and in-person encounters during COVID-19. Materials & methods: A retrospective chart review of 1000 encounters (500 telemedicine and 500 in-person) at an academic tertiary care comprehensive cancer center. Results: On average, overall, significantly higher narcotics (in morphine milligram equivalents [MME]) prescribed for patients receiving telemedicine services. In-person encounters had a significantly higher proportion of narcotic (in MME) increases in subsequent visits. Conclusion: Our institution continues to adapt telehealth services as an additional care venue and deeper insight helps mitigate development of maladaptive opioid prescribing patterns.

Erector spinae plane block versus local infiltration anaesthesia for transforaminal percutaneous endoscopic discectomy: A prospective randomised controlled trial.

BACKGROUND: Around 60%-80% of the population suffers from back pain, making it one of the most common health complaints. Transforaminal percutaneous endoscopic discectomy (TPED) is an effective treatment for low back pain that can be performed using different anaesthesia techniques. Our primary objective was to test the hypothesis that bilateral Erector spinae plane block (ESP) plus sedation is equally effective as traditional local infiltration anaesthesia plus sedation in TPED. MATERIALS AND METHODS: Fifty-two patients undergoing TPED were randomly assigned to 2 groups: G1 - intravenous sedation with local infiltration anaesthesia; G2 - intravenous sedation with bilateral ESP. PRIMARY OUTCOME: volume of fentanyl and propofol administered during surgery. SECONDARY OUTCOMES: adverse events during sedation reported using the World Society of Intravenous Anaesthesia (SIVA) adverse sedation event tool, level of postoperative sedation measured on the Richmond Agitation-Sedation Scale (RASS), intensity of postoperative pain on a visual analogue scale (VAS), mechanical pain threshold (MPT) measured with von Frey monofilaments on both lower extremities, patient satisfaction with analgesia on 5-point Likert scale. RESULTS: Volume of fentanyl, propofol, and level of postoperative sedation was significantly lower in G2 (p < 0.001). There was no difference between groups in intensity of pain, patient satisfaction with analgesia, and mechanical pain threshold after surgery. There were no adverse events in G2, but in G1 2 patients presented minimal risk descriptors, 5 presented minor risk descriptors, and 1 presented sentinel risk descriptors that required additional medication or rescue ventilation. CONCLUSIONS: The ESP was equal to local infiltration anaesthesia in terms of intensity of pain, mechanical pain threshold after surgery, and patient satisfaction; however, ESP reduced the volume of intraoperative fentanyl and propofol, thereby reducing the adverse effects of sedation.

Opioid-Free Discharge After Pancreatic Resection Through a Learning Health System Paradigm.

Importance: Postoperative opioid overprescribing leads to persistent opioid use and excess pills at risk for misuse and diversion. A learning health system paradigm using risk-stratified pancreatectomy clinical pathways (RSPCPs) may lead to reduction in inpatient and discharge opioid volume. Objective: To analyze the outcomes of 2 iterative RSPCP updates on inpatient and discharge opioid volumes. Design, Setting, and Participants: This cohort study included 832 consecutive adult patients at an urban comprehensive cancer center who underwent pancreatic resection between October 2016 and April 2022, comprising 3 sequential pathway cohorts (version [V] 1, October 1, 2016, to January 31, 2019 [n = 363]; V2, February 1, 2019, to October 31, 2020 [n = 229]; V3, November 1, 2020, to April 30, 2022 [n = 240]). Exposures: After V1 of the pathway established a baseline and reduced length of stay (n = 363), V2 (n = 229) updated patient and surgeon education handouts, limited intravenous opioids, suggested a 3-drug (acetaminophen, celecoxib, methocarbamol) nonopioid bundle, and implemented the 5×-multiplier (last 24-hour oral morphine equivalents [OME] multiplied by 5) to calculate discharge volume. Pathway version 3 (n = 240) required the nonopioid bundle as default in the recovery room and scheduled conversion to oral medications on postoperative day 1. Main Outcomes and Measures: Inpatient and discharge opioid volume in OME across the 3 RSPCPs were compared using nonparametric testing and trend analyses. Results: A total of 832 consecutive patients (median [IQR] age, 65 [56-72] years; 410 female [49.3%] and 422 male [50.7%]) underwent 541 pancreatoduodenectomies, 285 distal pancreatectomies, and 6 other pancreatectomies. Early nonopioid bundle administration increased from V1 (acetaminophen, 320 patients [88.2%]; celecoxib or anti-inflammatory, 98 patients [27.0%]; methocarbamol, 267 patients [73.6%]) to V3 (236 patients [98.3%], 163 patients [67.9%], and 238 patients [99.2%], respectively; P < .001). Total inpatient OME decreased from a median 290 mg (IQR, 157-468 mg) in V1 to 184 mg (IQR, 103-311 mg) in V2 to 129 mg (IQR, 75-206 mg) in V3 (P < .001). Discharge OME decreased from a median 150 mg (IQR, 100-225 mg) in V1 to 25 mg (IQR, 0-100 mg) in V2 to 0 mg (IQR, 0-50 mg) in V3 (P < .001). The percentage of patients discharged opioid free increased from 7.2% (26 of 363) in V1 to 52.5% (126 of 240) in V3 (P < .001), with 187 of 240 (77.9%) in V3 discharged with 50 mg OME or less. Median pain scores remained 3 or lower in all cohorts, with no differences in postdischarge refill requests. A subgroup analysis separating open and minimally invasive surgical cases showed similar results in both groups. Conclusions and Relevance: In this cohort study, the median total inpatient OME was halved and median discharge OME reduced to zero in association with a learning health system model of iterative opioid reduction that is freely adaptable by other hospitals. These findings suggest that opioid-free discharge after pancreatectomy and other major cancer operations is realistic and feasible with this no-cost blueprint.

Well-being, postoperative pain and outcome after clinical application of a novel root canal irrigation fluid-RISA-in teeth with apical periodontitis: A first-in-human study.

AIM: The aim of the study was to assess the tolerance to the new root canal irrigation fluid RISA after root canal treatment (RCT) by evaluating the subject's postoperative well-being, postoperative pain (PP) and treatment outcome. METHODOLOGY: A single-arm prospective study with 16 subjects (17 teeth) diagnosed with asymptomatic apical periodontitis. Endodontic treatment in one session performed using RISA for root canal irrigation. Well-being was assessed on the same day and after 24 h by telephone. For pain intensity, a visual analogue scale was used at 0-5 days. Clinical and radiographic evaluations were performed at ≥12 months. Well-being, occurrence of PP and outcome were qualitatively reported. Friedman test for paired samples and Spearman correlation coefficient were used. Significance was set at p < .05. RESULTS: At the same day and after 24 h, 14/16 subjects felt 'good'. 9/16 presented intra- or extra-oral swelling. The frequency of PP ≥36 (weak) was 82.4%. On the same day, 1 and 2 days postoperatively, there was more pain compared with preoperative pain p < .05. At Day 3, PP equalled preoperative pain (p > .05). 62.5% of subjects needed analgesics Day 0-2. The recall rate was 94.1%, and resolution of apical periodontitis was observed in 87.5%. CONCLUSIONS: The well-being of subjects was good, and the overall PP intensity was low. However, postoperative intra- and extra-oral swelling occurred often. At the recall visit, the effectiveness of the RCT with RISA appeared high (87.5%). The encouraging outcome results plus the fact that RISA has a broader action range than NaOCl in vitro, justify further work on the RISA solution. To reduce postoperative swelling, it is advised to further investigate the optimal way of application of RISA in the laboratory before clinical application is recommended.

Green Light-Based Analgesia - Novel Nonpharmacological Approach to Fibromyalgia Pain: A Pilot Study.

BACKGROUND: There continues to be significant reliance on pharmacological modalities for the management of chronic pain, with a particular focus on opioid analgesics as a singular option for pain management. Fibromyalgia is a prototypical central pain disorder, which is often used as a model to study chronic pain disorders. It has an estimated prevalence of approximately 1.1% to 5.4% in the general population. The widespread use of opioids in patients with fibromyalgia has been well demonstrated in several health claims database studies, with rates of use ranging from 11.3% to 69%. Minimizing opioid exposures reduces misuse risk, but requires adequate opioid-sparing multimodal analgesic strategies, particularly nonopioid analgesic adjuncts, to ensure effective treatment of pain, particularly high-impact pain. We chose fibromyalgia as our study population. Given that it is a disordered sensory processing condition, it may be particularly amenable to the beneficial effects of green-light therapy. OBJECTIVES: Most studies have evaluated exposure to light-emitting diode lights as a mode of green-light delivery; our study used green-light filtering eyeglasses, which would allow the wearer to move about with minimal interference. STUDY DESIGN: We conducted a randomized controlled trial to test the feasibility of green-light filtering eyeglasses in the treatment of chronic pain. SETTING: This study was conducted at Duke University Health System. METHODS: We recruited and randomized adult patients with a known diagnosis of fibromyalgia patients and excluded patients who were unable to wear eyeglasses for at least 4 hours per day or were colorblind according to the Ishihara Colorblindness Test. Patients were assigned to 1 of 3 arms: clear eyeglasses (control), green eyeglasses, or blue eyeglasses. We initially recruited 45 patients and randomly assigned 15 patients per group. RESULTS: To evaluate clinical significance, we determined the rate of >= 10% decline in oral morphine equivalents and found that 33%, 11%, and 8% of the green, blue, and clear eyeglass groups, respectively, achieved this clinically meaningful outcome. LIMITATIONS: This study was powered to detect feasibility of the intervention, rather than conclusive analgesic effects. CONCLUSIONS: Our study demonstrated the feasibility of this treatment approach and study design and supports a future study to determine the efficacy of green light-based analgesia on opioid use, pain, and anxiety. While the reduction of opioid use was not of statistical significance, we believe it to be of clinical significance as there was no increase of patient-reported pain. This warrants further investigation in a large-scale trial of the use of green-light filtration of ambient light to mitigate opioid use and possible mediation of psychological impacts of pain with the use of green-lensed eyeglasses.

Analysis of the Analgesic Effect, Emotion, and Safety of Esketamine in Cesarean Section Analgesia for Puerperae.

Objective: This retrospective study aimed to evaluate the effectiveness and safety of esketamine as an analgesic during cesarean section procedures. Methods: 102 puerperae undergoing cesarean section were divided into a control group and an esketamine (SK) group. Various parameters, including HR, MAP, and postoperative pain, were analyzed. Blood gas analysis and Apgar scores were assessed in neonates. Postoperative depression and satisfaction were evaluated in puerperae. Drug concentrations were measured using liquid-phase tandem mass spectrometry. Results: No significant differences in dimension levels were observed between the two groups (P > .05). However, the SK group showed better HR and MAP indicators at various time points, less postoperative pain, and better mental well-being on postpartum days 1, 3, and 7 (P < .05). Adverse reaction rates were similar between groups (P > .05), but postoperative satisfaction was significantly different (P = .027). Neonatal outcomes did not differ significantly (P > .05). In the SK group, SK2 and SK3 groups had better results compared to SK1 (P < .05). Conclusion: Esketamine during cesarean section stabilized vital signs, reduced pain, and improved well-being in puerperae without affecting newborns. Optimal dosage: 30 µg/kg/h esketamine, 15 ng/kg/h sufentanil.

Effects of Videos and Therapeutic Music on Preoperative Anxiety and Postoperative Anxiety and Pain Levels in Boys Who Undergo Circumcision.

PURPOSE: This purpose of this study was to investigate the effects of having boys aged 5 to 10 years who will undergo circumcision surgery watch informative videos and listen to therapeutic music on preoperative anxiety, and postoperative anxiety, pain, and nausea and vomiting. DESIGN: This was a prospective and ranomized controlled study. MATERIALS AND METHODS: The sample consisted of 90 boys aged 5 to 10 years who underwent circumcision surgery. The boys included in the study were randomly divided into 3 groups of 30 using a computer program. The first group (group V) watched the video; the second group (group M) listened to the music, and the third group (group C) was the control group with usual care. Boys and their parents were not blinded to the grouping. FINDINGS: Heart rate.ßvalues were found to be statistically significantly lower compared to the control group at the 1st minute after local anesthesia in group V (P.ß=.ß.029), at the 5th minute after local anesthesia in group M (P.ß=.ß.030), and at the 10th minute after local anesthesia and after the surgery in both group V and group M (P.ß=.ß.001 and P.ß=.ß.010, respectively). Wong-Baker Faces Pain Rating Scale.ßscores of the control group measured at the 2nd postoperative hour were found to be significantly higher than those of group V (P.ß=.ß.018). Children's Fear Scale.ßscores of group V measured at the time of admission to the postoperative service were found to be significantly higher than those of group M and group C (P.ß<.ß.001). There was no significant difference between the groups in terms of additional analgesic use, nausea and vomiting percentages, and time to discharge. CONCLUSIONS: The results of this study revealed that having boys aged 5 to 10 years who will undergo circumcision surgery watch informative videos and listen to therapeutic music did not have any significant effect on their postoperative pain, fear, and anxiety levels. Further large-scale studies, which will also include children who will not undergo circumcision surgery, are needed to generalize this study's results to larger populations.

The Use of Lavender Aromatherapy for Pain After Total Hip and Total Knee Arthroplasty: A Randomized Trial.

A randomized clinical trial was conducted over a threemonth period with 102 participants undergoing a total hip arthroplasty (THA) or total knee arthroplasty (TKA). The study purpose was to assess whether there was a reduction in the use of opioids in the postoperative period for THA or TKA participants that utilized lavender aromatherapy as an adjunct to pain medication. The participants in the control and intervention group were administered nonopioid pain medication around the clock and opioids as needed after surgery. However, the intervention group also received a pre-packaged lavender essential oil inhaler. Total oral morphine equivalents (OME) were calculated for each participant to determine opioid usage. Although the total OME was similar for the groups overall, the total OME was slightly lower for THA patients that were enrolled in the intervention group (median 22.5) compared to THA patients that were enrolled in the control group (median 31.2). In the intervention group, 58% of participants reported that the lavender inhaler was a useful tool for pain management and 76% indicated they would continue to use the lavender inhaler after discharge.
