The impact of timing, type, and method of instillation of intraperitoneal local anaesthetic in laparoscopic abdominal surgery: a systematic review and network meta-analysis. Br J Anaesth 2024; 132:562-574. [PMID: 38135524 DOI: 10.1016/j.bja.2023.11.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 11/05/2023] [Accepted: 11/08/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND Pain is common after laparoscopic abdominal surgery. Intraperitoneal local anaesthetic (IPLA) is effective in reducing pain and opioid use after laparoscopic surgery, although the optimum type, timing, and method of administration remains uncertain. We aimed to determine the optimal approach for delivering IPLA which minimises opioid consumption and pain after laparoscopic abdominal surgery. METHODS MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched for randomised controlled trials comparing different combinations of the type (bupivacaine vs lidocaine vs levobupivacaine vs ropivacaine), timing (pre-vs post-pneumoperitoneum at the beginning or end of surgery), and method (aerosol vs liquid) of IPLA instillation in patients undergoing any laparoscopic abdominal surgery. A network meta-analysis was conducted to ascertain the optimum approach for delivering IPLA resulting in the least cumulative opioid consumption and pain (overall and localising to the shoulder) 24 h after surgery. Certainty of evidence was evaluated using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) assessments (PROSPERO ID: CRD42022307595). RESULTS Twenty-five RCTs were included, among which 15 different combinations of delivering IPLA were analysed across 2401 participants. Aerosolised bupivacaine instilled at the end of surgery, before deflation of the pneumoperitoneum, was associated with significantly less postoperative opioid consumption compared with all other approaches for delivering IPLA (98.7% of comparisons; moderate certainty), aside from liquid levobupivacaine instilled before surgery and during or after creation of the pneumoperitoneum (mean difference -11.6, 95% credible interval: -26.1 to 2.5 i.v. morphine equivalent doses). There were no significant differences between different IPLA approaches regarding overall pain scores and incidence of shoulder pain up to 24 h after surgery. CONCLUSIONS There are limited studies and low-quality evidence to conclude on the optimum method of delivering IPLA in laparoscopic abdominal surgery. While aerosolised bupivacaine instilled at the end of surgery but before deflation of the pneumoperitoneum minimises postoperative opioid consumption, pain scores up to 24 h did not differ between the different modalities of delivering IPLA. The generalisability of these results is limited by the lack of utilisation of non-opioid analgesics in most trials. SYSTEMATIC REVIEW PROTOCOL REGISTRATION PROSPERO CRD42022307595.

Single-shot regional anesthesia for laparoscopic cholecystectomies: a systematic review and network meta-analysis. Korean J Anesthesiol 2023; 76:34-46.

Abstract
BACKGROUND Different regional anesthesia (RA) techniques have been used for laparoscopic cholecystectomy (LC), but there is no consensus on their comparative effectiveness. Our objective was to evaluate the effect of RA techniques on patients undergoing LC using a network meta-analysis approach. METHODS We conducted a systematic review and network meta-analysis. We searched PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and Web of Science (Science and Social Science Citation Index) using the following PICOS criteria: (P) adult patients undergoing LC; (I) any RA single-shot technique with injection of local anesthetics; (C) placebo or no intervention; (O) postoperative opioid consumption expressed as morphine milligram equivalents (MME), rest pain at 12 h and 24 h post-operation, postoperative nausea and vomiting (PONV), length of stay; and (S) randomized controlled trials. RESULTS A total of 84 studies were included. With the exception of the rectus sheath block (P = 0.301), the RA techniques were superior to placebo at reducing opioid consumption. Regarding postoperative pain, the transversus abdominis plane (TAP) block (-1.80 on an 11-point pain scale) and erector spinae plane (ESP) block (-1.33 on an 11-point pain scale) were the most effective at 12 and 24 h. The TAP block was also associated with the greatest reduction in PONV. CONCLUSIONS RA techniques are effective at reducing intraoperative opioid use, postoperative pain, and PONV in patients undergoing LC. Patients benefit the most from the bilateral paravertebral, ESP, quadratus lumborum, and TAP blocks.

J Anaesthesiol Clin Pharmacol 2021; 37:443-448. [PMID: 34759559 PMCID: PMC8562463 DOI: 10.4103/joacp.joacp_358_19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Revised: 01/04/2021] [Accepted: 03/07/2021] [Indexed: 11/11/2022] Open
Abstract
Background and Aims: Use of high dose opioids following laparoscopic surgery delays discharge from the hospital. Unlike intraperitoneal instillation, nebulization has been reported to provide a homogeneous spread of local anesthetics and provide better analgesia. In our study, we aimed to assess the efficacy of intraperitoneal nebulization of local anesthetic in alleviating postoperative pain in patients undergoing laparoscopic cholecystectomy. Material and Methods: This randomized control double-blinded study was conducted after obtaining approval from the hospital ethics committee and informed consent from patients undergoing laparoscopic cholecystectomy under general anesthesia. Patients recruited were divided into two equal groups of 20 each. Group B received intraperitoneal nebulization with 4 ml of 0.75% ropivacaine and Group C received intraperitoneal nebulization with 4ml of saline before surgical dissection. Postoperative pain score using a numeric rating scale was monitored until 24 h, the need for rescue analgesics and associated complications were noted. Chi-square test, Student's test, and Mann–Whitney U test were used for statistical analysis. Results: The pain score was significantly less in Group B during rest and deep breathing up to 24 h with a P value <0.05. The pain score on movement was also less in Group B and this difference was statistically significant at 6 and 24 h (P = 0.004 and 0.005, respectively). Tramadol consumption was less in Group B and was statistically significant at 24 h with P value of 0.044. No adverse events were noted. Conclusion: Intraperitoneal nebulization of ropivacaine is effective and safe in providing postoperative analgesia in patients undergoing laparoscopic cholecystectomy.

Abstract
BACKGROUND Pain is one of the important reasons for delayed discharge after laparoscopic cholecystectomy. Use of intraperitoneal local anaesthetic for laparoscopic cholecystectomy may be a way of reducing pain. A previous version of this Cochrane Review found very low-certainty evidence on the benefits and harms of the intervention. OBJECTIVES To assess the benefits and harms of intraperitoneal instillation of local anaesthetic agents in people undergoing laparoscopic cholecystectomy. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Trials, MEDLINE, Embase, and three other databases to 19 January 2021 together with reference checking of studies retrieved. We also searched five online clinical trials registries to identify unpublished or ongoing trials to 10 September 2021. We contacted study authors to identify additional studies. SELECTION CRITERIA We only considered randomised clinical trials (irrespective of language, blinding, publication status, or relevance of outcome measure) comparing local anaesthetic intraperitoneal instillation versus placebo, no intervention, or inactive control during laparoscopic cholecystectomy, for the review. We excluded non-randomised studies, and studies where the method of allocating participants to a treatment was not strictly random (e.g. date of birth, hospital record number, or alternation). DATA COLLECTION AND ANALYSIS Two review authors collected the data independently. Primary outcomes included all-cause mortality, serious adverse events, and quality of life. Secondary outcomes included length of stay, pain, return to activity and work, and non-serious adverse events. The analysis included both fixed-effect and random-effects models using RevManWeb. We performed subgroup, sensitivity, and meta-regression analyses. For each outcome, we calculated the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs). We assessed risk of bias using predefined domains, graded the certainty of the evidence using GRADE, and presented outcome results in a summary of findings table. MAIN RESULTS Eighty-five completed trials were included, of which 76 trials contributed data to one or more of the outcomes. This included a total of 4957 participants randomised to intraperitoneal local anaesthetic instillation (2803 participants) and control (2154 participants). Most trials only included participants undergoing elective laparoscopic cholecystectomy and those who were at low anaesthetic risk (ASA I and II). The most commonly used local anaesthetic agent was bupivacaine. Methods of instilling the local anaesthetic varied considerably between trials; this included location and timing of application. The control groups received 0.9% normal saline (69 trials), no intervention (six trials), or sterile water (two trials). One trial did not specify the control agent used. None of the trials provided information on follow-up beyond point of discharge from hospital. Only two trials were at low risk of bias. Seven trials received external funding, of these three were assessed to be at risk of conflicts of interest, a further 17 trials declared no funding. We are very uncertain about the effect intraperitoneal local anaesthetic versus control on mortality; zero mortalities in either group (8 trials; 446 participants; very low-certainty evidence); serious adverse events (RR 1.07; 95% CI 0.49 to 2.34); 13 trials; 988 participants; discharge on same day of surgery (RR 1.43; 95% CI 0.64 to 3.20; 3 trials; 242 participants; very low-certainty evidence). We found that intraperitoneal local anaesthetic probably results in a small reduction in length of hospital stay (MD -0.10 days; 95% CI -0.18 to -0.01; 12 trials; 936 participants; moderate-certainty evidence). No trials reported data on health-related quality of life, return to normal activity or return to work. Pain scores, as measured by visual analogue scale (VAS), were lower in the intraperitoneal local anaesthetic instillation group compared to the control group at both four to eight hours (MD -0.99 cm VAS; 95% CI -1.19 to -0.79; 57 trials; 4046 participants; low-certainty of evidence) and nine to 24 hours (MD -0.68 cm VAS; 95% CI -0.88 to -0.49; 52 trials; 3588 participants; low-certainty of evidence). In addition, we found two trials that were still ongoing, and one trial that was completed but with no published results. All three trials are registered on the WHO trial register. AUTHORS' CONCLUSIONS We are very uncertain about the effect estimate of intraperitoneal local anaesthetic for laparoscopic cholecystectomy on all-cause mortality, serious adverse events, and proportion of patients discharged on the same day of surgery because the certainty of evidence was very low. Due to inadequate reporting, we cannot exclude an increase in adverse events. We found that intraperitoneal local anaesthetic probably results in a small reduction in length of stay in hospital after surgery. We found that intraperitoneal local anaesthetic may reduce pain at up to 24 hours for low-risk patients undergoing laparoscopic cholecystectomy. Future randomised clinical trials should be at low risk of systematic and random errors, should fully report mortality and side effects, and should focus on clinical outcomes such as quality of life.

Abstract
BACKGROUND Laparoscopic cholecystectomy is a safe ambulatory procedure in appropriately selected patients; however, day case rates remain low. The objective of this systematic review and meta-analysis was to identify interventions which are effective in reducing the length of stay (LOS) or improving the day case rate for elective laparoscopic cholecystectomy. METHODS Comparative English-language studies describing perioperative interventions applicable to elective laparoscopic cholecystectomy in adult patients and their impact on LOS or day case rate were included. RESULTS Quantitative data were available for meta-analysis from 80 studies of 10,615 patients. There were an additional 17 studies included for systematic review. The included studies evaluated 14 peri-operative interventions. Implementation of a formal day case care pathway was associated with a significantly shorter LOS (MD = 24.9 h, 95% CI, 18.7-31.2, p < 0.001) and an improved day case rate (OR = 3.5; 95% CI, 1.5-8.1, p = 0.005). Use of non-steroidal anti-inflammatories, dexamethasone and prophylactic antibiotics were associated with smaller reductions in LOS. CONCLUSION Care pathway implementation demonstrated a significant impact on LOS and day case rates. A limited effect was noted for smaller independent interventions. In order to achieve optimal day case targets, a greater understanding of the effective elements of a care pathway and local barriers to implementation is required.

Abstract
BACKGROUND Intraperitoneal (IP) administration of local anesthetics is used in adults and children for postoperative analgesia after laparoscopic surgery. Population pharmacokinetics (PK) of IP bupivacaine has not been determined in children. Objectives of this study were (1) to develop a population PK model to compare IP bupivacaine administered via manual bolus atomization and micropump nebulization and (2) to assess postoperative morphine requirements after intraoperative administration. We hypothesized similar PK profiles and morphine requirements for both delivery methods. METHODS This was a prospective, sequential, observational study. After institutional review board (IRB) approval and written informed parental consent, 67 children 6 months to 6 years of age undergoing robot-assisted laparoscopic urological surgery received IP bupivacaine at the beginning of surgery. Children received a total dose of 1.25 mg/kg bupivacaine, either diluted in 30-mL normal saline via manual bolus atomization over 30 seconds or undiluted bupivacaine 0.5% via micropump nebulization into carbon dioxide (CO2) insufflation tubing over 10-17.4 minutes. Venous blood samples were obtained at 4 time points between 1 and 120 minutes intraoperatively. Samples were analyzed by liquid chromatography with mass spectrometry. PK parameters were calculated using noncompartmental and compartmental analyses. Nonlinear regression modeling was used to estimate PK parameters (primary outcomes) and Mann-Whitney U test for morphine requirements (secondary outcomes). RESULTS Patient characteristics between the 2 delivery methods were comparable. No clinical signs of neurotoxicity or cardiotoxicity were observed. The range of peak plasma concentrations was 0.39-2.44 µg/mL for the manual bolus atomization versus 0.25-1.07 μg/mL for the micropump nebulization. IP bupivacaine PK was described by a 1-compartment model for both delivery methods. Bupivacaine administration by micropump nebulization resulted in a significantly lower Highest Plasma Drug Concentration (Cmax) and shorter time to reach Cmax (Tmax) (P < .001) compared to manual bolus atomization. Lower plasma concentrations with less interpatient variability were observed and predicted by the PK model for the micropump nebulization (P < .001). Adjusting for age, weight, and sex as covariates, Cmax and area under the curve (AUC) were significantly lower with micropump nebulization (P < .001). Regardless of the delivery method, morphine requirements were low at all time points. There were no differences in cumulative postoperative intravenous/oral morphine requirements between manual bolus atomization and micropump nebulization (0.14 vs 0.17 mg/kg; P = .85) measured up to 24 hours postoperatively. CONCLUSIONS IP bupivacaine administration by micropump nebulization demonstrated lower plasma concentrations, less interpatient variability, low risk of toxicity, and similar clinical efficacy compared to manual bolus atomization. This is the first population PK study of IP bupivacaine in children, motivating future randomized controlled trials to determine efficacy.

Abstract
Laparoscopy, one of minimally invasive procedures, is a commonly used procedure in diagnosis and management of various kinds of clinical problems, including gynecologic organ-related diseases. Compared with conventional exploratory laparotomy, the benefits of laparoscopic surgery include reduction of surgical wound, decreasing in postoperative pain, shortening hospital stay, rapid recovery, and a better cosmetic result. However, there are still up to 80% of patients after laparoscopic surgery complaining of high levels of pain and needing pain relief. Postlaparoscopic pain can be separated into distinct causes, such as surgical trauma- or incision wound-associated inflammatory change, and pneumoperitoneum (carbon dioxide [CO2])-related morphological and biochemical changes of peritoneum and diaphragm. The latter is secondary to irritation, stretching, and foreign body stimulation, leading to phrenic neuropraxia and subsequent shoulder-tip pain (STP). STP is the most typical unpleasant experience of patients after laparoscopic surgery. There are at least 11 strategies available to attempt to decrease postlaparoscopic STP, including (1) the use of an alternative insufflating gas in place of CO2, (2) the use of low-pressure pneumoperitoneum in place of standard-pressure pneumoperitoneum, (3) the use of warmed or warmed and humidified CO2, (4) gasless laparoscopy, (5) subdiaphragmatic intraperitoneal anesthesia, (6) local intraperitoneal anesthesia, (7) actively expelling out of gas, (8) intraperitoneal drainage, (9) fluid instillation, (10) pulmonary recruitment maneuvers, and (11) others and combination. The present article is limited in discussing postlaparoscopic STP. We extensively review published articles to provide a better strategy to reduce postlaparoscopic STP.

Abstract
BACKGROUND Minimizing pain and disability are key postoperative objectives of robot-assisted distal pancreatectomy (RADP). This study tested effects of bupivacaine transversus abdominis plane (TAP) block on opioid consumption and pain after RADP. METHODS Retrospective case-control study (June 2012 -Oct 2017) evaluating bilateral intraoperative bupivacaine TAP block as an interrupted time series. Linear regression evaluated opioid consumption in terms of intravenous (IV) morphine milligram equivalents (MME) and controlled for preoperative morbidity. Secondary outcomes included numerical rating scale (NRS) pain scores. RESULTS 81 RADP patients met eligibility, 48 before and 33 after implementation of TAP. Baseline characteristics were equivalent with a trend toward higher age, Charlson comorbidity, and ASA score among the TAP cohort. TAP patients consumed on average 4.52 fewer IV MME than controls during the first six postoperative hours (p = 0.032) and reported lower mean NRS scores at six (p = 0.009) and 12 h (p = 0.006) but not at 24 h (p = 0.129). Postoperative morbidity and lengths of stay (LOS) were equivalent (5 vs. 6 days, p = 0.428). CONCLUSION Bupivacaine TAP block was associated with significant reductions in opioid consumption and pain after RADP but did not shorten hospital LOS consistent with bupivacaine's limited half-life.

Abstract
BACKGROUND Laparoscopic donor nephrectomy is considered less painful than open nephrectomy but is still associated with significant postoperative pain. Studies reported that intraperitoneal instillation of local anesthetics provides uncertain pain relief after laparoscopic surgery. This randomized, double-blind study evaluated the effect of intraperitoneal nebulization of ropivacaine on postoperative pain relief after laparoscopic donor nephrectomy. METHODS Sixty patients undergoing elective laparoscopic donor nephrectomy were randomly assigned to receive either an instillation of 20 ml 0.5% ropivacaine after the induction of pneumoperitoneum or nebulization of 5 ml 1% ropivacaine before and after surgery. The primary outcome was the degree of pain relief (static and dynamic) after surgery. The secondary outcomes were postoperative fentanyl consumption, incidence of shoulder pain, unassisted walking and postoperative nausea and vomiting (PONV). Data were collected in the postanesthesia care unit (PACU) and at 6, 24, and 48 h after surgery. RESULTS Compared to patients in the instillation group, those in the nebulization group showed significant reductions in postoperative pain and fentanyl consumption, and none complained of significant shoulder pain (visual analog scale score ≥ 30 mm). Within 20 h of surgery, 13.3% of patients in the instillation group and 93.3% in the nebulization group started unassisted walking (absolute risk reduction, 38%; P = 0.001). In the nebulization group, PONV was significantly reduced in the PACU and at 6 h. CONCLUSIONS Intraperitoneal nebulization of ropivacaine reduced postoperative pain, fentanyl consumption, referred shoulder pain, and PONV while enabling earlier mobility without any difference in the length of hospital stay.

Abstract
PURPOSE Postoperative pain remains a considerable concern for patients and families. We assessed whether nebulized ropivacaine reduces morphine consumption and pain after laparoscopic appendectomy for uncomplicated appendicitis in children. METHODS Patients 7-17 years old with uncomplicated appendicitis were randomized to ropivacaine (intervention arm) or saline nebulization (placebo arm) at the onset of laparoscopy. Nonconsenting individuals were treated with standard care and invited to provide clinical data (baseline arm). The primary outcome was in-patient morphine utilization. Secondary outcomes included pain scores at multiple time-points, markers of recovery, operative times, and surgeon satisfaction. The trial was registered (NCT02624089). RESULTS Study enrollment was 116 patients over a 1-year period: Intervention (n = 43), Placebo (n = 39), Baseline (n = 34). No differences in baseline characteristics were noted between groups. No difference was noted in overall in-patient morphine consumption between randomized groups (0.31 vs. 0.35 mg/kg, p = 0.42) or between ropivacaine and baseline (0.31 vs. 0.277 mg/kg, p = 0.62). Although operative times were comparable between groups, 63% of surgeon respondents felt that nebulization obscured visualization. CONCLUSION Nebulized ropivacaine did not reduce postoperative morphine consumption or pain scores after laparoscopic appendectomy for simple appendicitis in children. Given that it decreases visualization and likely increases costs, nebulized administration of intraperitoneal analgesia does not appear warranted in this context. TYPE OF STUDY Treatment study. LEVEL OF EVIDENCE Level I.

Abstract
PURPOSE Intraperitoneal local anesthetic nebulization is a new and novel technique for providing pain relief following laparoscopic cholecystectomy. We compared the analgesic efficacy of intraperitoneal ropivacaine-fentanyl nebulization with ropivacaine nebulization alone for providing pain relief following laparoscopic cholecystectomy Materials and Methods: This prospective, randomized, double-blind, placebo-controlled trial included 75 American Society of Anesthesiologists I/II patients, 18-60 years old, scheduled to undergo laparoscopic cholecystectomy under general anesthesia. Patients were randomly allocated to one of the three groups of 25 patients each to receive intraperitoneal nebulization using normal saline (group I), 30 mg of 0.75% ropivacaine (group II), or 30 mg of 0.75% ropivacaine with 100 μg fentanyl (group III). Visual analogue scale (VAS) scores for pain during rest and movement, shoulder pain, nausea or vomiting, and sedation were recorded for 48 hours postoperatively. Time to providing first rescue analgesia and 48-hour tramadol consumption were also noted. RESULTS Significantly greater number of patients in the placebo group had overall VAS >30 both at rest and during movement. Greater number of these patients also complained of postoperative shoulder pain and had significantly more tramadol consumption in the postoperative period. Furthermore, patients in the ropivacaine-fentanyl group demanded first dose of rescue analgesic significantly later than the other two groups. CONCLUSIONS Nebulization results in better and uniform dispersion of analgesic drug intraperitoneally. Following laparoscopic cholecystectomy surgeries, ropivacaine nebulization of intraperitoneal cavity, with or without fentanyl, provides highly effective postoperative analgesia, with decreased incidence of shoulder pain. Furthermore, addition of fentanyl to ropivacaine prolongs the duration of analgesia.

Surg Endosc 2018; 32:3321-3341.

Abstract
BACKGROUND Earlier studies done to compare the efficacy of use of local anesthetics at intraperitoneal location versus intraincisional use had utilized equal amount of drugs at the two locations, usually 10-20 ml. Using this large amount of drug in the small space of intraincisional location as compared to similar amount of drug in large intraperitoneal space created an inadvertent bias in favor of patients receiving the drug intraincisionally so these patients naturally experienced less pain. AIMS AND OBJECTIVES To conduct a randomized, triple-blind, placebo-controlled study by standardizing dose of local anesthetic, to compare the effectiveness of intraperitoneal against intraincisional use of ropivacaine 0.2% for post-laparoscopic cholecystectomy pain relief. MATERIALS AND METHODS 294 patients underwent elective 4-port laparoscopic cholecystectomy. Patients were triple blindly randomized. All patients received ~ 23 ml of solution, of which 20 ml was given intraperitoneally (1 ml/cm; 16 ml along right hemi-dome and 4 ml in gall bladder fossa) and ~ 3 ml intraincisionally (1 ml/cm of length of incision). Solution was either normal saline or drug (0.2% ropivacaine) depending on the group [controls (n = 86), intraperitoneal group (n = 100), and intraincisional group (n = 108)]. 5 different pain scales were used for assessment of overall pain. Pain scores were assessed at 5 points of time. RESULTS Patients in intraincisional group showed significantly less overall pain and rescue analgesia requirement (p < 0.05). Intraincisional group showed significantly less overall pain (p < 0.05) as compared to intraperitoneal group; however, use of rescue analgesia was comparable in the two groups (p > 0.05); and shoulder pain was significantly less in intraperitoneal group (p < 0.05). CONCLUSION The intraincisional use of injection ropivacaine at its minimum concentration of 0.2% in minimal doses of 1 ml/cm at the end of procedure provides significantly more post-operative analgesia as compared to intraperitoneal group and controls. However, for controlling shoulder pain, the use of intraperitoneal ropivacaine is desirable.

Abstract
BACKGROUND Pain is one of the important reasons for delayed discharge and Enhanced Recovery After Surgery (ERAS) after laparoscopic cholecystectomy. To assess the benefits and disadvantage of intraperitoneal instillation of ropivacaine in people undergoing laparoscopic cholecystectomy. METHODS We searched the MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and Science Citation Index Expanded to December 2016 to identify randomised clinical trials of relevance to this review. We analysed the data with Review Manager 5 analysis. MAIN RESULTS We identified 12 suitable studies. A total of 853 participants were randomised to intraperitoneal ropivacaine instillation (442 participants) versus "no intraperitoneal ropivacaine instillation" (411 participants). The pain scores as measured by the visual analogue scale (VAS) were significantly lower in the ropivacaine instillation group than the control group at 4-8 h (10 trials; 751 participants; MD -0.64 cm; 95% CI -0.86 to -0.43; p < 0.00001) and at 9-24 h (9 trials; 582 participants; MD -0.47 cm; 95% CI -0.66 to -0.28; p < 0.00001).The proportion of people who developed the adverse events were less in the ropivacaine instillation group than the control group(RR 0.60; 95% CI 0.45 to 0.79; p = 0.0002). There was no significant difference in the Post-anesthesia care unit (PACU) stay time between the two groups (3 trials; 197 participants; MD -3.77 min; 95% CI -10.24 to 2.69). The overall quality of evidence was very low. Further trials are necessary.

Abstract
In the later half of the 20th century, nebulized therapy was in decline, but in the 21st century the prospects for the expanded use of nebulized therapy within respiratory medicine look bright. The advent of mesh nebulizers, which combine the universal applicability of the nebulizer in the treatment of all respiratory patients with the convenience of portable inhaler use, is ideally timed to capitalize on the forecast of increased numbers of patients who will require nebulized therapy in the future. This special report will highlight some of the opportunities that the development of mesh nebulizers presents in the field of respiratory medicine.

Abstract
Background. Intraperitoneal nebulization of ropivacaine reduces postoperative pain and morphine consumption after laparoscopic surgery. The aim of this multicenter double-blind randomized controlled trial was to assess the efficacy of different doses and dose-related absorption of ropivacaine when nebulized in the peritoneal cavity during laparoscopic cholecystectomy. Methods. Patients were randomized to receive 50, 100, or 150 mg of ropivacaine 1% by peritoneal nebulization through a nebulizer. Morphine consumption, pain intensity in the abdomen, wound and shoulder, time to unassisted ambulation, discharge time, and adverse effects were collected during the first 48 hours after surgery. The pharmacokinetics of ropivacaine was evaluated using high performance liquid chromatography. Results. Nebulization of 50 mg of ropivacaine had the same effect of 100 or 150 mg in terms of postoperative morphine consumption, shoulder pain, postoperative nausea and vomiting, activity resumption, and hospital discharge timing (>0.05). Plasma concentrations did not reach toxic levels in any patient, and no significant differences were observed between groups (P > 0.05). Conclusions. There is no enhancement in analgesic efficacy with higher doses of nebulized ropivacaine during laparoscopic cholecystectomy. When administered with a microvibration-based aerosol humidification system, the pharmacokinetics of ropivacaine is constant and maintains an adequate safety profile for each dosage tested.

Abstract
BACKGROUND Provision of optimal postoperative analgesia should facilitate postoperative ambulation and rehabilitation. An optimal multimodal analgesia technique would include the use of nonopioid analgesics, including local/regional analgesic techniques such as surgical site local anesthetic infiltration. This article presents a novel approach to surgical site infiltration techniques for abdominal surgery based upon neuroanatomy. METHODS Literature searches were conducted for studies reporting the neuroanatomical sources of pain after abdominal surgery. Also, studies identified by preceding search were reviewed for relevant publications and manually retrieved. RESULTS Based on neuroanatomy, an optimal surgical site infiltration technique would consist of systematic, extensive, meticulous administration of local anesthetic into the peritoneum (or preperitoneum), subfascial, and subdermal tissue planes. The volume of local anesthetic would depend on the size of the incision such that 1 to 1.5 mL is injected every 1 to 2 cm of surgical incision per layer. It is best to infiltrate with a 22-gauge, 1.5-inch needle. The needle is inserted approximately 0.5 to 1 cm into the tissue plane, and local anesthetic solution is injected while slowly withdrawing the needle, which should reduce the risk of intravascular injection. CONCLUSIONS Meticulous, systematic, and extensive surgical site local anesthetic infiltration in the various tissue planes including the peritoneal, musculofascial, and subdermal tissues, where pain foci originate, provides excellent postoperative pain relief. This approach should be combined with use of other nonopioid analgesics with opioids reserved for rescue. Further well-designed studies are necessary to assess the analgesic efficacy of the proposed infiltration technique.

Abstract
The previous articles of the Statistical Round in the Korean Journal of Anesthesiology posed a strong enquiry on the issue of null hypothesis significance testing (NHST). P values lie at the core of NHST and are used to classify all treatments into two groups: "has a significant effect" or "does not have a significant effect." NHST is frequently criticized for its misinterpretation of relationships and limitations in assessing practical importance. It has now provoked criticism for its limited use in merely separating treatments that "have a significant effect" from others that do not. Effect sizes and CIs expand the approach to statistical thinking. These attractive estimates facilitate authors and readers to discriminate between a multitude of treatment effects. Through this article, I have illustrated the concept and estimating principles of effect sizes and CIs.

Abstract
Laparoscopic surgery is widespread, and an increasing number of surgeries are performed laparoscopically. Early pain after laparoscopy can be similar or even more severe than that after open surgery. Thus, proactive pain management should be provided. Pain after laparoscopic surgery is derived from multiple origins; therefore, a single agent is seldom sufficient. Pain is most effectively controlled by a multimodal, preventive analgesia approach, such as combining opioids with non-opioid analgesics and local anaesthetics. Wound and port site local anaesthetic injections decrease abdominal wall pain by 1-1.5 units on a 0-10 pain scale. Inflammatory pain and shoulder pain can be controlled by NSAIDs or corticosteroids. In some patient groups, adjuvant drugs, ketamine and α2-adrenergic agonists can be helpful, but evidence on gabapentinoids is conflicting. In the present review, the types of pain that need to be taken into account while planning pain management protocols and the wide range of analgesic options that have been assessed in laparoscopic surgery are critically assessed. Recommendations to the clinician will be made regarding how to manage acute pain and how to prevent persistent postoperative pain. It is important to identify patients at the highest risk for severe and prolonged post-operative pain, and to have a proactive strategy in place for these individuals.

Abstract
BACKGROUND Postoperative pain can cause physiological distress, postoperative complications, and extended lengths of hospitalized stay. In children, management of postoperative pain is still recognized as being inadequate. OBJECTIVE The aim of this trial was to investigate the effects of intraperitoneal ropivacaine on postoperative pain, and recovery of bowel function and emetic events after laparoscopic herniorrhaphy in toddlers. METHODS Seventy-six children aged from 9 months to 3 years were recruited between August 2013 and June 2014 at Tongji Hospital and randomly assigned into two groups. One group received intraperitoneal ropivacaine right before surgery and the control group received intraperitoneal saline. A standard combined general anesthesia procedure was performed under regular monitoring. Postoperative pain was assessed by the FLACC scale. Postoperative analgesic consumption, time to flatus, time to first stool, and postoperative emetic events were also recorded. RESULTS When compared with the control group, children who received intraperitoneal ropivacaine experienced less pain 0-4 h after surgery [P < 0.001, difference in median FLACC (95% CI) for 2 h time point is 2.00 (0.87-3.13), for 4 h time point is 1.00 (0.55-1.45)]. In addition, the number of toddlers who received analgesia 0-24 h after surgery in the ropivacaine group was lower than that in the control group [P < 0.001, difference in proportions (95% CI) is 0.575 (0.3865-0.7638)]. Compared with the control group, time to flatus in ropivacaine group was also much shorter [21.1 h vs 16.7 h, P = 0.04, difference in mean (95% CI) is 4.4 (1.49-7.28)], and the time to first stool after surgery was earlier in the ropivacaine group [30.7 h vs 25.6 h, P = 0.003, difference in mean (95% CI) is 5.1 (1.78-8.45)]. Furthermore, the incidence of emetic events in the ropivacaine group was significantly lower than the control group [32.4% vs 11.1%, P = 0.03, difference in proportions (95% CI) is 0.212 (0.0246-0.4002)]. CONCLUSION The present results indicate that intraperitoneal ropivacaine reduces early postoperative pain and improves recovery after laparoscopic herniorrhaphy in toddlers. Therefore, IPLA is a good stratagem for postoperative pain management after laparoscopic surgery in toddlers.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the thermographic predictive value of local anesthetic poisoning in rats that indicates the early recognition of thermal signs of intoxication and enable the immediate start of advanced life support. METHODS Wistar rats underwent intraperitoneal injection of saline and ropivacaine; they were allocated into pairs, and experiments performed at baseline and experimental times. For thermography, central and peripheral compartment were analyzed, checking the maximum and average differences of temperatures between groups. Thermographic and clinical observations were performed for each experiment, and the times in which the signs of intoxication occurred were recorded. In the thermal analysis, the thermograms corresponding to the times of interest were sought and relevant data sheets extracted for statistical analysis. RESULTS Basal and experimental: the display of the thermal images at times was possible. It was possible to calculate the heat transfer rate in all cases. At baseline it was possible to see the physiology of microcirculation, characterized by thermal distribution in the craniocaudal direction. It was possible to visualize the pathophysiological changes or thermal dysautonomias caused by intoxication before clinical signs occur, characterized by areas of hyper-radiation, translating autonomic nervous system pathophysiological disorders. In animals poisoned by ropivacaine, there was no statistically significant difference in heat transfer rate at the experimental time. CONCLUSIONS The maximum temperature, medium temperature, and heat transfer rate were different from the statistical point of view between groups at the experimental time, thus confirming the systemic thermographic predictive value.

Abstract
BACKGROUND Postoperative pain remains a significant challenge following laparoscopy. Aerosolized intraperitoneal local anesthetic (AILA) is a novel method to deliver local anesthetic. The aim was to evaluate aerosolized ropivacaine in pain management following laparoscopic Nissen fundoplication (LNF) and cholecystectomy (LC). METHODS This prospective randomized double-blinded placebo-controlled trial enrolled consecutive patients undergoing LNF and LC. The treatment group (TG) received intraperitoneal ropivacaine (5 mL 1 % Naropin(®)) at CO2 insufflation via the AeroSurge(®) aerosolizer device through the camera port. The control group (CG) received 5 mL of saline in the same manner. Postoperative shoulder tip pain at rest 6 h postoperatively was the primary study endpoint, with secondary endpoints of shoulder and abdominal pain within the first 24 h, recovery room stay, hospital stay, and postoperative analgesia use. Pain scores were collected using the Verbal Rating Score. RESULTS Eighty-seven patients were included in the final analysis (TG n = 40, CG n = 47). There was no significant difference between CG and TG at the primary endpoint. In the LC group, AILA significantly reduced shoulder tip pain at rest at 10 (p = 0.030) and 30 min (p = 0.040) and shoulder tip pain on movement at 10 (p = 0.030) and 30 min (p = 0.037). In the LNF group, AILA significantly reduced postoperative abdominal pain at rest at 6 h (p = 0.009). AILA reduced overall incidence of shoulder tip pain in the LC group (11.8 vs. 57.9 %, p = 0.004). CONCLUSION This study did not demonstrate a significant difference between TG and CG in the primary endpoint, pain at 6 h postoperatively.

Abstract
BACKGROUND AND AIMS Poorly managed acute postoperative pain may result in prolonged morbidity. Various pharmacotherapies have targeted this, but research on an ideal preemptive analgesic continues, taking into account drug-related side effects. Considering the better tolerability profile of tapentadol, we assessed its role as a preemptive analgesic in the reduction of postoperative analgesic requirements, after laparoscopic cholecystectomy. MATERIAL AND METHODS In a prospective-double-blinded fashion, sixty patients posted for above surgery, were randomized to receive tablet tapentadol 75 mg (Group A) or starch tablets (Group B) orally, an hour before induction of general anesthesia. Perioperative analgesic requirement, time to first analgesia, pain, and sedation score were compared for first 24 h during the postoperative period and analyzed by one-way analysis of variance test. A P < 0.05 was considered significant. RESULTS Sixty patients were analyzed. The perioperative analgesic requirement was significantly lower in Group A. Verbal numerical score was significantly lower in Group A at the time point, immediately after shifting the patient to the postanesthesia care unit. Ramsay sedation scores were similar between the groups. No major side effects were observed except for nausea and vomiting in 26 cases (10 in Group A, 16 in Group B). CONCLUSION Single preemptive oral dose of tapentadol (75 mg) is effective in reducing perioperative analgesic requirements and acute postoperative pain, without added side effects. It could be an appropriate preemptive analgesic, subjected to future trials concentrating upon its dose-response effects.

Abstract
AIM: To systematically evaluate the effect of intraperitoneal local anesthetic on pain characteristics after laparoscopic cholecystectomy (LC).
METHODS: We searched MEDLINE, EMBASE, and the Cochrane Library. Randomized controlled trials in English that compared the effect of intraperitoneal administration of local anesthetics on pain with that of placebo or nothing after elective LC under general anesthesia were included. The primary outcome variables analyzed were the combined scores of abdominal, visceral, parietal, and shoulder pain after LC at multiple time points. We also extracted pain scores at resting and dynamic states.
RESULTS: We included 39 studies of 3045 patients in total. The administration of intraperitoneal local anesthetic reduced pain intensity in a resting state after laparoscopic cholecystectomy: abdominal [standardized mean difference (SMD) = -0.741; 95%CI: -1.001 to -0.48, P < 0.001]; visceral (SMD = -0.249; 95%CI: -0.493 to -0.006, P = 0.774); and shoulder (SMD = -0.273; 95%CI: -0.464 to -0.082, P = 0.097). Application of intraperitoneal local anesthetic significantly reduced the incidence of shoulder pain (RR = 0.437; 95%CI: 0.299 to 0.639, P < 0.001). There was no favorable effect on resting parietal or dynamic abdominal pain.
CONCLUSION: Intraperitoneal local anesthetic as an analgesic adjuvant in patients undergoing laparoscopic cholecystectomy exhibited beneficial effects on postoperative abdominal, visceral, and shoulder pain in a resting state.

Abstract
STUDY OBJECTIVE To compare the effects of local anesthetic intraperitoneal nebulization with intraperitoneal instillation during laparoscopic ovarian cystectomy on postoperative morphine consumption and pain. DESIGN Multicenter, randomized, case-control trial. DESIGN CLASSIFICATION Canadian Task Force Classification I. SETTING University hospitals in Italy. PATIENTS One hundred forty patients scheduled for laparoscopic ovarian cystectomy. INTERVENTIONS Patients were randomized to receive either nebulization of ropivacaine 150 mg before surgery or instillation of ropivacaine 150 mg before surgery. Nebulization was performed using the Aeroneb Pro device (Aerogen, Galway, Ireland). MEASUREMENTS AND MAIN RESULTS One hundred forty patients were enrolled, and 123 completed the study. There was no difference between the 2 groups in average morphine consumption (7.3 ± 7.5 mg in the nebulization group vs 9.2 ± 7.2 mg in the instillation group; p = .17). Eighty-two percent of patients in the nebulization group required morphine compared with 96% in the instillation group (p < .05). Patients receiving nebulization had a lower dynamic Numeric Ranking Scale compared with those in the instillation group in the postanesthesia care unit postanesthesia care unit and 4 hours after surgery (p < .05). Ten patients (15%) in the nebulization group experienced shivering in the postanesthesia care unit compared with 2 patients (4%) in the instillation group (p = .035). CONCLUSION Nebulization of ropivacaine prevents the use of morphine in a significant proportion of patients, reduced postoperative pain during the first hours after surgery, and was associated with a higher incidence of postoperative shivering when compared with instillation.

Abstract
Background: Gasretention in the peritoneal cavity plays an important role in inducing postoperative pain after laparoscopy, which is inevitably retained in the peritoneal cavity. Objectives: The aim of this study was to detect the relation between the volume of residual gas and severity of shoulder and abdominal pain. Patients and Methods: In this Prospective study 55 women who were referred for laparoscopic cholecystectomy, were evaluated for the effect of residual pneumoperitoneum on postlaparoscopic cholecystectomy pain intensity. The pneumoperitoneum was graded as absent, mild (1-5 mm), moderate (6-10 mm) and severe (> 11 mm). Patients were followed for postoperative abdominal and shoulder pain using visual analogue scale (VAS), postoperative analgesic requirements, presence of nausea and vomiting, time of unassisted ambulation, time of oral intake and time of return of bowel function in the recovery room and at 6, 12 and 24 hours after operation. Results: At the end of the study, 17 patients (30.9%) had no residual pneumoperitoneum after 24 hours; which 23 (41.81%) had mild residual pneumoperitoneum, eight (14.54%) had moderate pneumoperitoneum and seven (12.72%) had severe pneumoperitoneum. Patients with no or mild residual pneumoperitoneum had significantly lower abdominal and shoulder pain scores than whom with moderate to severe pneumoperitoneum (P = 0.00) and need less meperidine requirements (P = 0.00). Patients did not have any significant difference in time of oral intake, return of bowel function, nausea and vomiting percentages. Conclusions: We conclude that volume of residual pneumoperitoneum is a contributing factor in the etiology of postoperative pain after laparoscopic cholecystectomy.

Abstract
STUDY OBJECTIVE To evaluate the effects of peritoneal cold nebulization of ropivacaine on pain control after gynecologic laparoscopy. DESIGN Evidence obtained from a properly designed, randomized, double-blind, placebo-controlled trial (Canadian Task Force classification I). SETTING Tertiary care center. PATIENTS One hundred thirty-five women with American Society of Anesthesiologists disease classified as ASA I-III who were scheduled to undergo operative laparoscopy. INTERVENTION Patients were randomized to receive either nebulization of 30 mg ropivacaine before surgery (preoperative group), nebulization of 30 mg ropivacaine after surgery (postoperative group), instillation of 100 mg ropivacaine before surgery (instillation group), or instillation of saline solution (control group). Nebulization was performed using the Aeroneb Pro device. MEASUREMENT AND MAIN RESULTS Pain scores, morphine consumption, and ambulation time were collected in the post-anesthesia care unit and at 4, 6, and 24 hours postoperatively. One hundred eighteen patients completed the study. Patients in the preoperative group reported lower pain Numeric Ranking Scale values compared with those in the control group (net difference 2 points; 95% confidence interval [CI], 0.3-3.1 at 4 hours, 1-3 at 6 hours, and 0.7-3 at 24 hours; p = .01) Patients in the preoperative group consumed significantly less morphine than did those in the control group (net difference 7 mg; 95% CI, 0.7-13; p = .02). More patients who received nebulization walked without assistance within 12 hours after awakening than did those in the instillation and control groups (net difference 15%; 95% CI, 6%-24%; p = .001). CONCLUSIONS Cold nebulization of ropivacaine before surgery reduced postoperative pain and morphine consumption and was associated with earlier walking without assistance.

Abstract
BACKGROUND Intraperitoneal local anaesthetic instillation may decrease pain in people undergoing laparoscopic cholecystectomy. However, the optimal method to administer the local anaesthetic is unknown. OBJECTIVES To determine the optimal local anaesthetic agent, the optimal timing, and the optimal delivery method of the local anaesthetic agent used for intraperitoneal instillation in people undergoing laparoscopic cholecystectomy. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded, and the World Health Organization International Clinical Trials Registry Platform portal (WHO ICTRP) to March 2013 to identify randomised clinical trials for assessment of benefit and comparative non-randomised studies for the assessment of treatment-related harms. SELECTION CRITERIA We considered only randomised clinical trials (irrespective of language, blinding, or publication status) comparing different methods of local anaesthetic intraperitoneal instillation during laparoscopic cholecystectomy for the review. DATA COLLECTION AND ANALYSIS Two review authors collected the data independently. We analysed the data with both fixed-effect and random-effects models using Review Manager 5 analysis. For each outcome, we calculated the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI). MAIN RESULTS We included 12 trials with 798 participants undergoing elective laparoscopic cholecystectomy randomised to different methods of intraperitoneal local anaesthetic instillation. All the trials were at high risk of bias. Most trials included only people with low anaesthetic risk. The comparisons included in the trials that met the eligibility criteria were the following; comparison of one local anaesthetic agent with another local anaesthetic agent (three trials); comparison of timing of delivery (six trials); comparison of different methods of delivery of the anaesthetic agent (two trials); comparison of location of the instillation of the anaesthetic agent (one trial); three trials reported mortality and morbidity.There were no mortalities or serious adverse events in either group in the following comparisons: bupivacaine (0/100 (0%)) versus lignocaine (0/106 (0%)) (one trial; 206 participants); just after creation of pneumoperitoneum (0/55 (0%)) versus end of surgery (0/55 (0%)) (two trials; 110 participants); just after creation of pneumoperitoneum (0/15 (0%)) versus after the end of surgery (0/15 (0%)) (one trial; 30 participants); end of surgery (0/15 (0%)) versus after the end of surgery (0/15 (0%)) (one trial; 30 participants).None of the trials reported quality of life, the time taken to return to normal activity, or the time taken to return to work. The differences in the proportion of people who were discharged as day-surgery and the length of hospital stay were imprecise in all the comparisons included that reported these outcomes (very low quality evidence). There were some differences in the pain scores on the visual analogue scale (1 to 10 cm) but these were neither consistent nor robust to fixed-effect versus random-effects meta-analysis or sensitivity analysis. AUTHORS' CONCLUSIONS The currently available evidence is inadequate to determine the effects of one method of local anaesthetic intraperitoneal instillation compared with any other method of local anaesthetic intraperitoneal instillation in low anaesthetic risk individuals undergoing elective laparoscopic cholecystectomy. Further randomised clinical trials of low risk of systematic and random errors are necessary. Such trials should include important clinical outcomes such as quality of life and time to return to work in their assessment.

Abstract
BACKGROUND Abdominal pain and shoulder tip pain after laparoscopic cholecystectomy are distressing for the patient. Various causes of this pain are peritoneal stretching and diaphragmatic irritation by high intra-abdominal pressure caused by pneumoperitoneum . We designed a study to compare the post operative pain after laparoscopic cholecystectomy at low pressure (7-8 mm of Hg) and standard pressure technique (12-14 mm of Hg). Aim : To compare the effect of low pressure and standard pressure pneumoperitoneum in post laparoscopic cholecystectomy pain . Further to study the safety of low pressure pneumoperitoneum in laparoscopic cholecystectomy. SETTINGS AND DESIGN A prospective randomised double blind study. MATERIALS AND METHODS A prospective randomised double blind study was done in 100 ASA grade I & II patients. They were divided into two groups -50 each. Group A patients underwent laparoscopic cholecystectomy with low pressure pneumoperitoneum (7-8 mm Hg) while group B underwent laparoscopic cholecystectomy with standard pressure pneumoperitoneum (12-13 mm Hg). Both the groups were compared for pain intensity, analgesic requirement and complications. STATISTICAL ANALYSIS Demographic data and intraoperative complications were analysed using chi-square test. Frequency of pain, intensity of pain and analgesics consumption was compared by applying ANOVA test. RESULTS Post-operative pain score was significantly less in low pressure group as compared to standard pressure group. Number of patients requiring rescue analgesic doses was more in standard pressure group . This was statistically significant. Also total analgesic consumption was more in standard pressure group. There was no difference in intraoperative complications. CONCLUSION This study demonstrates the use of simple expedient of reducing the pressure of pneumoperitoneum to 8 mm results in reduction in both intensity and frequency of post-operative pain and hence early recovery and better outcome.This study also shows that low pressure technique is safe with comparable rate of intraoperative complications.

Abstract
BACKGROUND The aim of preemptive analgesia is to reduce central sensitization that arises from noxious inputs across the entire perioperative period. N-methyl d-aspartate receptor antagonists have the potential for attenuating central sensitization and preventing central neuroplasticity. MATERIALS AND METHODS Patients undergoing laparoscopic cholecystectomy were randomized into four groups of 20 patients each, who were administered the study drug intravenously 30 min before incision. Groups A, B, and C received ketamine in a dose of 1.00, 0.75 and 0.50 mg/kg, respectively, whereas group D received isotonic saline. Anesthetic and surgical techniques were standardized. Postoperatively, the degree of pain at rest, movement, and deep breathing using visual analogue scale, time of request for first analgesic, total opioid consumption, and postoperative nausea and vomiting were recorded in postanesthesia care unit for 24 h. RESULTS Pain scores were highest in Group D at 0 h. Groups A, B, and C had significantly decreased postoperative pain scores at 0, 0.5, 3, 4, 5, 6, and 12 h. Postoperative analgesic consumption was significantly less in groups A, B, and C as compared with group D. There was no significant difference in the pain scores among groups A, B, and C. Group A had a significantly higher heart rate and blood pressure than groups B and C at 0 and 0.5 h along with 10% incidence of hallucinations. CONCLUSION Preemptive ketamine has a definitive role in reducing postoperative pain and analgesic requirement in patients undergoing laparoscopic cholecystectomy. The lower dose of 0.5 mg/kg being devoid of any adverse effects and hemodynamic changes is an optimal dose for preemptive analgesia in patients undergoing laparoscopic cholecystectomy.
