During the past decade the use of epidural opioids for treatment of chronic as well as postoperative pain has increased Epidural droperidol significantly reduced the side effects of epidural morphine without any appreciable toxicity, except possibly sedation. The purpose of this study was to assess the side effects and potentiation of analgesia of epidural morphine by dose-related droperidol. The results were as follows: 1) Duration of analgesia and pain score: There was no significant difference between morphine and dose-related droperidol groups. 2) Pruritus: Droperidol did not affect the incidence of pruritus with epidural morphine (P>0.05). 3) Nausea and vomiting: Significantly fewer patients experienced nausea and vomiting (16.7%) with droperidol 2.5mg(P<0.001). 4) Hypotensive episode Hypotension occurred in the groups with droperidol 1.25 mg (27. 8%) and 2.5mg(33.3%). 5) Sedation: It there was increased severity and incidence of sedation with dose related epidural droperidol. 6) Respiratory depression: There was no patient with respiratory depression in the morphine or droperidol group. 7) Extrapyramidal symptoms and others: There was no extrapyramidal symptom in the group with morphine and 0.25 mg droperidol, but 3 patients in the group with l.25 mg droperidol and 5 patients in the group with 2.5 mg droperidol how extrapyramidal symptoms. One patient in droperidol 2.5 mg developed suspicious NMS. It is suggested that the use of epidural droperidol to reduce the side effects of morphine may not be appropriate.
Background Pain in the postoperative body contouring patient has traditionally been managed with narcotic medication. In an effort to minimize side effects and prevent addiction, plastic surgeons are searching for novel ways to provide adequate analgesia, one of which is nerve blocks. This study was conducted with a meta-analysis that evaluates the efficacy of these blocks for patients who undergo breast surgery. Methods A search of the PubMed/MEDLINE database for articles including the terms "post-operative analgesia" OR "postoperative pain management" AND "in plastic surgery" OR "in cosmetic surgery" OR "in elective surgery" in February 2019 generated five studies on elective breast augmentation and reduction mammoplasty that reported pain scores and quantities of opioids consumed. Independent samples t-tests, one-way analysis of variance, and a random effects model were implemented for evaluation. Results A total of 317 patients were identified as having undergone body contouring of the breast, about half of which received a nerve block. Pain scores on a 1-10 scale and opioid dose-equivalents were calculated. Those who were blocked had an average score of 2.40 compared to 3.64 for those who did not (P<0.001), and required an average of 5.20 less narcotic doses (P<0.001). Pain relief following subpectoral augmentation was best achieved with type-II blocks as opposed to type-I and type-II with serratus plane (P<0.001). Conclusions The opioid epidemic has extended to all surgical specialties. Implementation of a nerve block seems to be an efficacious and cost-effective mechanism to not only help with post-operative pain, but also lower the need for narcotics, especially in subpectoral augmentation.
Background: The primary indication for using long-acting anesthetics in dentistry is extensive dental procedures that require pulpal anesthesia beyond 90 min and management of postoperative pain. Ropivacaine is an amide local anesthetic that is available at various concentrations with inherent vasoconstrictive properties at low concentrations. Ropivacaine has a 75% greater margin of safety than bupivacaine. Ropivacaine can be a good alternative to bupivacaine as a local anesthetic in dental implant surgery as it provides a longer duration of both pulpal and soft tissue anesthesia after mandibular nerve block and lowers CNS and cardiovascular toxicity. This study aimed to evaluate and compare the clinical efficacy of ropivacaine and lignocaine for implant surgery anesthesia. Methods: Fifteen patients with bilateral edentulous sites indicated for implant placement were recruited for this study. Patients aged 20-60 years of both sexes were randomly recruited. Thirty implant placements were performed in the test and control groups using ropivacaine and lignocaine with adrenaline as local anesthetics, respectively. Results: The results were analyzed statistically. The duration of anesthesia was significantly higher in the test group than in the control group. Ropivacaine was found to be superior to lignocaine in terms of the quality of anesthesia. The comparison of mean visual analog scale scores showed ropivacaine to have better anesthetic and analgesic effects than the control group. Conclusion: Ropivacaine 0.75% provides a significantly longer duration of anesthesia than lignocaine 2% with adrenaline. Ropivacaine 0.75% decreased intraoperative and postoperative analgesia compared to lignocaine 2% with adrenaline. Hence, ropivacaine 0.75% can be used as an alternative to lignocaine in implant surgeries and other intraoral surgical procedures that require a longer duration of anesthesia and analgesia.

Objectives: Inferior alveolar nerve block (IANB) is commonly used for mandibular dentoalveolar surgery. The objective of this study was to evaluate and compare the effectiveness of coadministration of dexamethasone (4 mg/mL) or adrenaline (0.01 mg/mL) as an adjuvant with lignocaine 2% in IANB during third molar surgery (TMS). Patients and Methods: This double-blind, randomized controlled trial was conducted between March and August 2020. The investigators screened patients needing elective TMS under local anesthesia. Based on strict inclusion and exclusion criteria, patients were enrolled in this study. These patients were assigned randomly into two study groups: dexamethasone group (DXN) or adrenaline group (ADN). Outcome variables were postoperative edema, trismus, visual analogue scale (VAS), perioperative analgesia, onset time, and duration of IANB. Results: Eighty-three patients were enrolled in this study, of whom 23 (27.7%) were eliminated or excluded during follow-up. This study thus included data from 60 samples. Mean age was 32.28±11.74 years, including 28 females (46.7%) in the ADN (16 patients, 57.1%) and DXN (12 patients, 42.9%) groups. The duration of action for DXN (mean±standard deviation [SD], 4:02:07±0:34:01 hours; standard error [SE], 0:06:00 hours; log-rank P=0.001) and for ADN (mean±SD, 1:58:34±0:24:52 hours; SE, 0:04:42 hours; log-rank P=0.001) were found. Similarly, time at which 1st analgesic consume and total number of nonsteroidal antiinflammatory drugs need to rescue postoperative analgesia was found statistically significant between study groups (t (58)=-11.95; confidence interval, -2:25:41 to -1:43:53; P=0.001). Early-hours VAS was also significantly different between the study groups. Conclusion: A single injection of dexamethasone prolongs the duration of action of lignocaine 2% IANB. Additionally, it can be used in cases where adrenaline is contraindicated.
Background: Nowadays, epidural morphine is commonly used in postoperative pain control. But epidural morphine may produce some side-effects, e.g. pruritus, nausea, vomiting, urinary retention and respiratory depression. Especially, pruritus is the most common complaint in pain-controlled patients by epidural morphine. So we evaluated whether addition of epidural butorphanol affects the degree of pruritus and pain score in pain controlled patients who by epidural morphine after hysterectomy. Methods: Group 1(N=15) received postoperative epidural 0.1% bupivacaine 100ml plus morphine 10 mg, group 2(N=15) received the mixture of butorphanol 2 mg with same regime as in group 1, group 3(N=15) received the mixture of butorphanol 4 mg with same regime as in group 1. All of the three groups received these solutions by infusion pump, 1 ml/hour, for postoperative 4 days. all groups received additional morphine 1.2 mg in 0.2% bupivacaine 6ml epidurally when the peritoneum was closed under general anesthesia. The severity of pain, pruritus, nausea and vomiting was estimated by 10 cm VAS(visual analogue scale) and somnolence by positive or negative during postoperative 4 days. Results: Severity of pruritus, but not nausea and vomiting was decreased in group 2 and 3 compared with group 1(p<0.05). Pain score was increased in group 3 at postoperative day(POD) 0 and 2 compared with group 1(p<0.05). Incidence of somnolence in group 1, 2 and 3 were $2.7{\pm}0.7,\;5.3{\pm}0.7$ and $10.0{\pm}1.0$ respectively. Conclusion: These results suggest that butorphanol reduce the degree of pruritus, the most common side effect of morphine, but increase the incidence of somnolence.
The present study compared the postoperative analgesic effects of ilioinguinal and iliohypogastric nerve block with infiltration of local anesthetics (bupivacaine) into the wound in children after inguinal hernia repair. Ninety children below 7 years old who were scheduled elective inguinal hernia repair were randomly allocated into one of three groups. The patients in nerve block (NB) group, ilioinguinal and iliohypogastric nerve block was done with 0.5 mL/kg of 0.25% bupivacaine. The patients in infiltration of local anesthetics (LI) group, 0.5 mL/kg of 0.25% bupivacaine was infiltrated into the wound after surgery. The patients in control group were allocated as a Control group. Postoperative pain was assessed at 1, 3, 5, and 24 hours after operation with FLACC scale and additional analgesic consumption were counted. The three groups were not significantly different in age, sex, body weight, and duration of operation. Pain scores at 1 hour and 3 hours after operation were significantly higher in Control group than in NB group and LI group (p<0.01), whereas there were no difference between NB group and LI group. The rescue analgesics administration was significantly higher in Control group (n=11) than in NB group (n=6) and LI group (n=7) (p<0.05). There were 2 cases of transient femoral nerve palsy in NB group. Both of ilioinguinal and iliohypogastric nerve block and infiltration of local anesthetics into the wound provided effective postoperative analgesia in early postoperative period following inguinal hernia repair in children. But no difference between the two methods. Technically, infiltration of local anesthetics into the wound was easier and safer than ilioinguinal and iliohypogastric nerve block.

Background The deep inferior epigastric artery perforator (DIEP) flap is the commonest flap used for breast reconstruction after mastectomy. It is performed as a unilateral (based on one [unipedicled] or two [bipedicled] vascular pedicles) or bilateral procedure following unilateral or bilateral mastectomies. No previous studies have comprehensively analyzed analgesia requirements and hospital stay of these three forms of surgical reconstruction. Methods A 7-year retrospective cohort study (2008-2015) of a single-surgeon's DIEP-patients was conducted. Patient-reported pain scores, patient-controlled morphine requirements and recovery times were compared using non-parametric statistics and multivariable regression. Results The study included 135 participants: unilateral unipedicled (n=84), unilateral bipedicled (n=24) and bilateral unipedicled (n=27). Univariate comparison of the three DIEP types showed a significant difference in 12-hour postoperative morphine requirements (P=0.020); bipedicled unilateral patients used significantly less morphine than unipedicled (unilateral) patients at 12 (P=0.005), 24 (P=0.020), and 48 (P=0.046) hours. Multivariable regression comparing these two groups revealed that both reconstruction type and smoking status were significant predictors for 12-hour postoperative morphine usage (P=0.038 and P=0.049, respectively), but only smoking, remained significant at 24 (P=0.010) and 48 (P=0.010) hours. Bilateral reconstruction patients' mean hospital stay was 2 days longer than either unilateral reconstruction (P<0.001). Conclusions Although all three forms of DIEP flap breast reconstruction had similar postoperative pain measures, a novel finding of our study was that bipedicled DIEP flap harvest might be associated with lower early postoperative morphine requirements. Bilateral and bipedicled procedures in appropriate patients might therefore be undertaken without significantly increased pain/morbidity compared to unilateral unipedicled reconstructions.

Background: Postoperative pain management following minimally invasive repair of pectus excavatum (MIRPE) remains a critical concern due to severe post-procedural pain. Promising results have been reported for cryoanalgesia following MIRPE; however, its invasiveness, single-lung ventilation, and additional instrumentation requirements remain obstacles. Serratus anterior plane block (SAPB) is a regional block technique capable of covering the anterior chest wall at the T2-9 levels, which are affected by MIRPE. We hypothesized that SAPB would be a superior alternative pain control modality that reduces postoperative pain more effectively than conventional methods. Methods: We conducted a retrospective study of patients who underwent MIRPE between March 2022 and August 2023. The efficacy of pain control was compared between group N (conventional pain management, n=24) and group S (SAPB, n=26). Group N received intravenous patient-controlled analgesia (IV-PCA) and subcutaneous local anesthetic infusion. Group S received bilateral continuous SAPB with 0.3% ropivacaine after a bilateral bolus injection of 30 mL of 0.25% ropivacaine with baseline IV-PCA. Pain levels were evaluated using a Visual Analog Scale (VAS) at 1, 3, 6, 12, 24, 48, and 72 hours postoperatively and total intravenous rescue analgesic consumption by morphine milligram equivalents (MME). Results: Mean VAS scores were significantly lower in group S than in group N throughout the 72-hour postoperative period (p<0.01). Group S showed significantly lower MME at postoperative 72 hours (group N: 108.53, group S: 16.61; p<0.01). Conclusion: SAPB improved immediate postoperative pain control in both the resting and dynamic states and reduced opioid consumption compared to conventional management.
Purpose: The purpose of this study was to identify pain intensity according to activities over postoperative days and to identify factors of patient satisfaction with pain management after abdominal surgery. Methods: The subjects were 123 patients who were admitted at a general surgical ward and had abdominal surgery from Mar. 2005 to June 2005. The collected data were analyzed using the SPSS 12.0 program. Results: The average postoperative pain scores were 6.13 at POD 1, 5.46 at POD 2, and 4.22 at POD 3. In stepwise multiple regression analysis a total of 40% of variance in satisfaction with pain management was accounted for by pain intensity on POD 3 at rest (29.4%) and attitude toward using pain medicine (6.6%), and side effects of pain medicine (4.0%). Conclusion: According to the findings of this study, patients had inadequate pain management after abdominal surgery. Therefore, nurses need to provide educational programs focused on changing attitudes toward using pain medicine, to reduce side effects of pain medicine, and to develop nursing intervention for relieving pain.
Objective : A prospective, randomized, controlled clinical study is performed to verify the effectiveness of epidural dexamethasone-soaked gelatin sponges to reduce postoperative pain following lumbar microdiscectomy. Methods : Twenty-three patients (10 men and 13 women) undergoing lumbar microdiscectomy were included. Five pieces of gelatin sponge measuring $1{\times}1cm$ [Gelfoam; Pharmacia & Upjohn. Kalamazoo, MI, USA], soaked with either 5mg dexamethasone or an equal amount [2mL] of saline, were left on the decompressed nerve root after unilateral hemilami-nectomy, flavectomy and discectomy. Results : Subjective visual analog scale[VAS] scores of leg pain in the dexamethasone group on the first, third and first postoperative days [2.5, 2.5, 1.7, respectively] were significantly lower than in the control group [5.0, 4.8, 3.6][P<0.05]. No side effects related to the dexamethasone-soaked gelatin sponges were observed. Conclusion : The intraoperative application of dexamethasone-soaked gelatin sponges during lumber microdiscetomy can provide effective-postoperative analgesia without complications.
