Abstract
IMPORTANCE The opioid crisis is impacting people across the country and deserves attention to be able to curb the rise in opioid-related deaths. OBJECTIVES To evaluate practice patterns in opioid infusion administration and dosing for patients with acute respiratory failure receiving invasive mechanical ventilation. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS Patients from 21 hospitals in Kaiser Permanente Northern California and 96 hospitals in Philips electronic ICU Research Institute. MAIN OUTCOMES AND MEASURES We assessed whether patients received opioid infusion and the dose of said opioid infusion. RESULTS We identified patients with a diagnosis of acute respiratory failure who were initiated on invasive mechanical ventilation. From each patient, we determined if opioid infusions were administered and, among those who received an opioid infusion, the median daily dose of fentanyl infusion. We used hierarchical regression models to quantify variation in opioid infusion use and the median daily dose of fentanyl equivalents across hospitals. We included 13,140 patients in the KPNC cohort and 52,033 patients in the eRI cohort. A total of 7,023 (53.4%) and 16,311 (31.1%) patients received an opioid infusion in the first 21 days of mechanical ventilation in the KPNC and eRI cohorts, respectively. After accounting for patient- and hospital-level fixed effects, the hospital that a patient was admitted to explained 7% (95% CI, 3-11%) and 39% (95% CI, 28-49%) of the variation in opioid infusion use in the KPNC and eRI cohorts, respectively. Among patients who received an opioid infusion, the median daily fentanyl equivalent dose was 692 µg (interquartile range [IQR], 129-1341 µg) in the KPNC cohort and 200 µg (IQR, 0-1050 µg) in the eRI cohort. Hospital explained 4% (95% CI, 1-7%) and 20% (95% CI, 15-26%) of the variation in median daily fentanyl equivalent dose in the KPNC and eRI cohorts, respectively. CONCLUSIONS AND RELEVANCE In the context of efforts to limit healthcare-associated opioid exposure, our findings highlight the considerable opioid exposure that accompanies mechanical ventilation and suggest potential under and over-treatment with analgesia. Our results facilitate benchmarking of hospitals' analgesia practices against risk-adjusted averages and can be used to inform usual care control arms of analgesia and sedation clinical trials.

Abstract
Importance Guidelines recommend an analgesia-first strategy for sedation during mechanical ventilation, but associations between opioids provided during mechanical ventilation and posthospitalization opioid-related outcomes are unclear. Objective To evaluate associations between an intravenous opioid dose received during mechanical ventilation and postdischarge opioid-related outcomes in medical (nonsurgical) patients. Design, Setting, and Participants This retrospective cohort study evaluated adults receiving mechanical ventilation lasting 24 hours or more for acute respiratory failure and surviving hospitalization. Participants from 21 Kaiser Permanente Northern California hospitals from January 1, 2012, to December 31, 2019, were included. Data were analyzed from October 1, 2020, to October 31, 2023. Exposures Terciles of median daily intravenous fentanyl equivalents during mechanical ventilation. Main Outcomes and Measures The primary outcome was the first filled opioid prescription in 1 year after discharge. Secondary outcomes included persistent opioid use and opioid-associated complications. Secondary analyses tested for interaction between opioid doses during mechanical ventilation, prior opioid use, and posthospitalization opioid use. Estimates were based on multivariable-adjusted time-to-event analyses, with death as a competing risk, and censored for hospice or palliative care referral, rehospitalization with receipt of opioid, or loss of Kaiser Permanente plan membership. Results The study included 6746 patients across 21 hospitals (median age, 67 years [IQR, 57-76 years]; 53.0% male). Of the participants, 3114 (46.2%) filled an opioid prescription in the year prior to admission. The median daily fentanyl equivalent during mechanical ventilation was 200 μg (IQR, 40-1000 μg), with terciles of 0 to 67 μg, more than 67 to 700 μg, and more than 700 μg. Compared with patients who did not receive opioids during mechanical ventilation (n = 1013), a higher daily opioid dose was associated with opioid prescriptions in the year after discharge (n = 2942 outcomes; tercile 1: adjusted hazard ratio [AHR], 1.00 [95% CI, 0.85-1.17], tercile 2: AHR, 1.20 [95% CI, 1.03-1.40], and tercile 3: AHR, 1.25 [95% CI, 1.07-1.47]). Higher doses of opioids during mechanical ventilation were also associated with persistent opioid use after hospitalization (n = 1410 outcomes; tercile 3 vs no opioids: odds ratio, 1.44 [95% CI, 1.14-1.83]). No interaction was observed between opioid dose during mechanical ventilation, prior opioid use, and posthospitalization opioid use. Conclusions and Relevance In this retrospective cohort study of patients receiving mechanical ventilation, opioids administered during mechanical ventilation were associated with opioid prescriptions following hospital discharge. Additional studies to evaluate risks and benefits of strategies using lower opioid doses are warranted.

Abstract
Opioid-free anesthesia (OFA) is a heterogeneous group of general anesthesia techniques in which the intraoperative use of opioids is eliminated. This strategy aims to decrease the risk of complications and improve the patient's safety and comfort. Such potential advantages are particularly beneficial for selected groups of patients, among them obese patients undergoing laparoscopic bariatric surgery. Opioids have been traditionally used as an element of balanced anesthesia, and replacing them requires using a combination of coanalgesics and various types of local and regional anesthesia, which also have their side effects, limitations, and potential disadvantages. Moreover, despite the growing amount of evidence, the empirical data on the superiority of OFA compared to standard anesthesia with multimodal analgesia are contradictory, and potential benefits in many studies are being questioned. Additionally, little is known about the long-term sequelae of such a strategy. Considering the above-mentioned issues, this study aims to present the potential benefits, risks, and difficulties of implementing OFA in bariatric surgery, considering the current state of knowledge and literature.

Abstract
Adequate management of acute pain in the older population is crucial. However, it is inherently complex because of multiple physiological changes that significantly impact both the pharmacokinetics and pharmacodynamics of medications. Current guidelines promote paracetamol as the first-line analgesic for acute pain in older adults, whereas opioids are advised cautiously for moderate to severe acute pain. However, opioids come with a significant array of side effects, which can be more pronounced in older individuals. Ketamine administered via intranasal (IN) and nebulised inhalation in the emergency department for managing acute pain in older patients shows promising potential for improving pain management and reducing opioid reliance Kampan, Thong-on, Sri-on (2024, Age Ageing, 53, afad255). Nebulised ketamine appears superior in terms of adverse event incidence. However, the adoption of IN or nebulised ketamine in older adult acute pain management remains unclear because of the lack of definitive conclusions and clear guidelines. Nevertheless, these modalities can be valuable options for patients where opioid analgesics are contraindicated or when intravenous morphine titration is impractical or contraindicated. Here, we review these concepts, the latest evidence and propose avenues for research.

Abstract
BACKGROUND Postoperative pain after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is important. It appears essential to reduce postoperative pain and morphine consumption. METHODS Retrospective study in a university hospital comparing patient benefiting from CRS-HIPEC under opioid-free anesthesia (OFA; dexmedetomidine) to those anesthetized with opioid anesthesia (OA; remifentanil) using a propensity score matching method. The main objective was the impact of OFA on postoperative morphine consumption in the first 24 h after surgery. RESULTS 102 patients were included, matching on the propensity score allowed selecting 34 unique pairs analyzed. Morphine consumption was lower in the OFA group than in the OA group (3.0 [0.00-11.0] mg/24 h vs. 13.0 [2.5-25.0] mg/24 h; p = 0.02). In multivariable analysis, OFA was associated with a reduction of 7.2 [0.5-13.9] mg of postoperative morphine (p = 0.04). The rate of renal failure with a KDIGO-score > 1 was lower in the OFA group than in the OA group (12% vs. 38%; p = 0.01). There was no difference between groups concerning length of surgery/anesthesia, norepinephrine infusion, volume of fluid therapy, post-operative complications, rehospitalization or ICU readmission within 90 days, mortality, and postoperative rehabilitation. CONCLUSION Our results suggest that OFA for CRS-HIPEC patients appears safe and is associated with less postoperative morphine use and acute kidney injury.

J Pain Res 2024; 17:941-951. [PMID: 38476874 PMCID: PMC10929647 DOI: 10.2147/jpr.s449563] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 02/23/2024] [Indexed: 03/14/2024] Open
Abstract
Purpose The methods of perioperative analgesia and pain control have changed. The principle of opioid-based analgesia has been modified to multimodal analgesia, followed by LOA (low opioid anaesthesia) and OFA (opioid-free anaesthesia). The aim was to describe the effects of LOA on nausea, vomiting, and pain control during general anaesthesia and postoperative period after laparoscopic cholecystectomy. Patients and Methods The protocol included the study group-40 patients received low-opioid anaesthesia (LOA), and the control group-40 patients received general anaesthesia with opioid analgesia (OA). The scheme of LOA was based on ketamine, lidocaine, magnesium sulfate, paracetamol, and metamizole. The OA was based on standard opioid (fentanyl) administration in induction and maintenance phase due to clinical observation. Postoperative analgesia included 1g of paracetamol and 1g of metamizol intravenously, with a 6-hour interval between doses. Results Significant differences in the pain score in the periods of 2-6, 6-12, and 12-24 hours after anaesthesia between the groups were noticed (p < 0.001). Moreover, a significant difference in the frequency of nausea (p = 0.005) and vomiting (p = 0.04) between groups were presented. Nausea occurred in 54.05% of OA group, while in the LOA group, it occurred in a 23.08%. Vomiting occurred in 32.43% of control group, while in the study group, it occurred in 12.82% of patients. Conclusion The LOA protocol was more beneficial in reducing nausea and vomiting than the opioid-based method of anaesthesia. The LOA protocol of general anaesthesia during laparoscopic cholecystectomy and non-opioid postoperative analgesia have better outcomes in pain control, as well as nausea and vomiting, and improve postoperative patient comfort. The LOA protocol during anaesthesia and non-opioid postoperative analgesia should be considered in routine practice.

Abstract
BACKGROUND This study aimed to observe the effect of opioid-free anaesthesia (OFA) on intraoperative haemodynamic,postoperative analgesia and postoperative nausea and vomiting (PONV) in thoracoscopic surgery in order to provide more evidence for evaluating the safety and effectiveness of OFA technology. METHODS This was a single-centre retrospective observational study.Adult patients who underwent thoracoscopic surgery with the preoperative thoracic paravertebral block between January 2017 and June 2020 were included.A cohort of 101 thoracoscopic surgery patients who received the OFA technique were matched with 101 thoracoscopic surgery patients who received standard opioid-containing anaesthesia(SOA). Heart rate (HR) and mean arterial blood pressure (MAP) were measured before anaesthesia induction, immediately after endotracheal intubation, at the beginning of surgery, and 10, 20, and 30 min after surgery began.The total amount of intraoperative infusion, frequency of vasoactive drugs use, morphine ingested via the patient-controlled intravenous analgesia (PCIA) 24 h post-surgery,visual analogue scale (VAS) scores at rest and activity on the first day post-surgery, and frequency of nausea and vomiting within 24 h post-surgery were analysed. RESULTS There was no significant difference in intraoperative HR between the two groups (F = 0.889, P = 0.347); however, there was significant difference in intraoperative MAP (F = 16.709, P < 0.001), which was lower in SOA patients than in OFA patients. The frequency of vasoactive drug use and amount of infusion was less in OFA patients (P = 0.001). The consumption of morphine used by the PCIA 24 h post-surgery was significantly lower in OFA patients (OFA, 1.8 [0, 4.8] mg vs. SOA, 3.6 [0.6, 23] mg, P < 0.001). There was no significant difference in VAS scores at rest (P = 0.745) or during activity (P = 0.792) on the first day post-surgery. There was also no statistically significant difference in nausea and vomiting within 24 h post-surgery (P = 0.651). CONCLUSIONS This case-control study demonstrated that compared with SOA, OFA can effectively maintain the stability of intraoperative MAP, reduce the incidence of hypotension. Although OFA reduced morphine consumption via the PCIA pump 24 h post-surgery, postoperative pain scores and nausea and vomiting within 24 h post-surgery were similar between the groups.But this study was only a preliminary study and needed to confirm in a larger, more robust trial.

Abstract
Minimally invasive cardiac surgery (MICS) has been used since the 1990s and encompasses a wide range of techniques that lack full sternotomy, including valve and coronary artery graft surgery as well as transcatheter procedures. Due to the potential benefits offered to patients by MICS, these procedures are becoming more common. Unique anaesthetic knowledge and skills are required to overcome the specific challenges presented by MICS, including mastery of transoesophageal echocardiography (TOE) and the provision of thoracic regional analgesia. This review evaluates the relevance of MICS to the anaesthetist and discusses pre-operative assessment, the relevant adjustments to intra-operative conduct that are necessary for these techniques, as well as post-operative care and what is known about outcomes.

Abstract
Background Opioids have been used as pain relievers for thousands of years. However, they may also cause undesirable side effects. We therefore performed this study to compare the effect of opioid-free anesthesia (OFA) versus opioid-sparing anesthesia (OSA) on postoperative pain and patient-controlled epidural analgesia (PCEA)-related events. Methods This is a single center randomized clinical trial that was recruited patients aged from 18 to 70 years who received video-assisted lung surgery between October 2021 and February 2022. Participants were 1:1 randomly assigned to OFA or OSA. Patients in the OFA group received propofol, rocuronium, esmolol, lidocaine, and magnesium sulfate intravenously with epidural ropivacaine. Patients in the OSA group received propofol, rocuronium, remifentanil, and sufentanil intravenously with epidural hydromorphone and ropivacaine. Results A total number of 124 patients were randomly allocated to the OFA or OSA group. In the OFA group, the severity of pain during coughs on the first postoperative days (PODs; VAS score 1.88 ± 0.88 vs. 2.16 ± 1.1, p = 0.044) was significantly lower than that in the OSA group. The total ratio of PCEA-related adverse events in the OFA group [11 (19.6%) vs. 26 (47.3%), p = 0.003] was significantly lower than in the OSA group. Conclusion OFA in patients who received video-assisted lung surgery led to lower severity of acute postoperative motion-induced pain and fewer PCEA-related adverse events on the first POD than in the patients in the OSA group.

Abstract
BACKGROUND Despite their extensive clinical use, opioids are characterized by several side effects. These complications, coupled with the ongoing opioid epidemic, have favored the rise of opioid-free-anesthesia (OFA). Herein, we perform the first pairwise meta-analysis of clinical outcomes for OFA vs opioid-based anesthesia (OBA) in patients undergoing cardiovascular and thoracic surgery. METHODS We comprehensively searched medical databases to identify studies comparing OFA and OBA in patients undergoing cardiovascular or thoracic surgery. Pairwise meta-analysis was performed using the Mantel-Haenszel method. Outcomes were pooled as risk ratios (RR) or standard mean differences (SMD) and their 95% confidence intervals (95% CI). RESULTS Our pooled analysis included 919 patients (8 studies), of whom 488 underwent surgery with OBA and 431 with OFA. Among cardiovascular surgery patients, compared to OBA, OFA was associated with significantly reduced post-operative nausea and vomiting (RR, 0.57; P = .042), inotrope need (RR .84, P = .045), and non-invasive ventilation (RR, .54; P = .028). However, no differences were observed for 24hr pain score (SMD, -.35; P = .510) or 48hr morphine equivalent consumption (SMD, -1.09; P = .139). Among thoracic surgery patients, there was no difference between OFA and OBA for any of the explored outcomes, including post-operative nausea and vomiting (RR, 0.41; P = .025). CONCLUSION Through the first pooled analysis of OBA vs OFA in a cardiothoracic-exclusive cohort, we found no significant difference in any of the pooled outcomes for thoracic surgery patients. Although limited to 2 cardiovascular surgery studies, OFA was associated with significantly reduced postoperative nausea and vomiting, inotrope need, and non-invasive ventilation in these patients. With growing use of OFA in invasive operations, further studies are needed to assess their efficacy and safety in cardiothoracic patients.

Efficacy of intravenous dexmedetomidine-lignocaine infusion compared to morphine for intraoperative haemodynamic stability in modified radical mastectomy: A randomised controlled trial. Indian J Anaesth 2023; 67:697-702. [PMID: 37693035 PMCID: PMC10488572 DOI: 10.4103/ija.ija_581_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 05/19/2023] [Accepted: 05/19/2023] [Indexed: 09/12/2023] Open
Abstract
Background and Aims In recent times, non-opioid analgesic-based anaesthesia has been gaining popularity as it can achieve the goals of hypnosis, amnesia, and haemodynamic stability while avoiding opioid side effects. Our study compares the efficacy of opioid-free anaesthesia and opioid-based general anaesthesia regarding intraoperative haemodynamic stability, anaesthetic requirements, awareness, and recovery profile. Methods After receiving ethical approval and registering the trial, we conducted this randomised, single-blinded study on American Society of Anesthesiologists (ASA) physical status I and II patients who were aged 18-65 and were scheduled for modified radical mastectomy under general anaesthesia. Patients were randomised into two groups of 60 each. Group DL received IV dexmedetomidine 1 μg/kg loading over 10 min, 10 min before induction and 0.5 μg/kg/h infusion after that along with IV lignocaine 1.5 mg/kg at bolus followed by 1.5 mg/kg/h infusion. Group MN received IV morphine 0.15 mg/kg. Standard monitoring and general anaesthesia protocol were followed. Intraoperative haemodynamics, anaesthetic requirement, extubation time, and recovery profile were monitored. Data were analysed using Stata version 14 software, and statistical tests (Chi-squared test for qualitative variables, unpaired t-test and Mann-Whitney U test for quantitative variables) were performed. Results Both groups had comparable haemodynamic stability (P > 0.05). Group DL had a significantly lower propofol requirement for induction and maintenance (P < 0.001). Ramsay sedation score (P = 0.002) and extubation time (P = 0.029) were significantly higher in Group MN. The recovery profile was favourable in Group DL, with there being lower postoperative complications. Conclusion Dexmedetomidine and lignocaine IV infusion demonstrated stable intraoperative haemodynamic stability, lower anaesthetic requirement, and better recovery profile than morphine without significant complications.

Abstract
The aim of this study was to evaluate the feasibility of opioid-free anesthesia (OFA) in open radical cystectomy (ORC) with urinary diversion and to assess the impact on recovery of gastrointestinal function. We hypothesized that OFA would lead to earlier recovery of bowel function. A total of 44 patients who underwent standardized ORC were divided into two groups (OFA group vs. control group). In both groups, patients received epidural analgesia (OFA group: bupivacaine 0.25%, control group: bupivacaine 0.1%, fentanyl 2 mcg/mL, and epinephrine 2 mcg/mL). The primary endpoint was time to first defecation. Secondary endpoints were incidence of postoperative ileus (POI) and incidence of postoperative nausea and vomiting (PONV). The median time to first defecation was 62.5 h [45.8-80.8] in the OFA group and 118.5 h [82.6-142.3] (p < 0.001) in the control group. With regard to POI (OFA group: 1/22 patients (4.5%); control group: 2/22 (9.1%)) and PONV (OFA group: 5/22 patients (22.7%); control group: 10/22 (45.5%)), trends but no significant results were found (p = 0.99 and p = 0.203, respectively). OFA appears to be feasible in ORC and to improve postoperative functional gastrointestinal recovery by halving the time to first defecation compared with standard fentanyl-based intraoperative anesthesia.

Abstract
This study aimed to compare the analgesic effects of an injectable protocol using multimodal analgesia with or without opioids in cats undergoing ovariohysterectomy (OVH). Thirty-two healthy cats were enrolled in a prospective, blinded, randomized trial after the caregiver's written consent. Cats received a combination of ketamine (4 mg/kg), midazolam (0.25 mg/kg) and dexmedetomidine (40 μg/kg), and either buprenorphine (20 μg/kg) or saline (same volume as buprenorphine) intramuscularly [opioid-sparing (OSA) and opioid-free anesthesia (OFA) groups, respectively]. Intraperitoneal bupivacaine 0.25% (2 mg/kg) and meloxicam (0.2 mg/kg subcutaneously) were administered before OVH. Atipamezole (400 μg/kg intramuscularly) was administered at the end of surgery. Pain and sedation were evaluated using the Feline Grimace Scale (FGS) and a dynamic interactive visual analog scale, respectively. Intravenous buprenorphine was administered as rescue analgesia if FGS scores ≥ 0.39/1. Statistical analysis included repeated measures linear mixed models, Fisher's exact test and Bonferroni adjustments when appropriate (p < 0.05). Twenty-seven cats were included. The prevalence of rescue analgesia was lower in OSA (n = 0/13) than in OFA (n = 5/14) (p = 0.04). The FGS scores (least square means and 95% CI) were higher in OFA at 1 [2.0 (1.3-2.7)] and 2 h [2.2 (1.5-2.9)] than baseline [0.7 (0.0-1.4)], but not in OSA. Sedation scores were not significantly different between groups. Opioid-free injectable anesthesia was appropriate for some cats using a multimodal approach. However, a single dose of intramuscular buprenorphine eliminated the need for rescue analgesia and assured adequate pain management after OVH in cats.

Ventriculoatrial Shunt Under Locoregional Anesthesia: A Technical Note. World Neurosurg 2022; 166:135-140. [PMID: 35870783 DOI: 10.1016/j.wneu.2022.07.057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 07/12/2022] [Accepted: 07/13/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Ventriculoatrial shunt is routinely performed under general anesthesia and is used to treat various kinds of hydrocephalus. Idiopathic normal pressure hydrocephalus patients are generally elderly and can have high comorbidities; in such patients, avoiding general anesthesia and limiting opioid administration could be beneficial. We started to perform ventriculoatrial shunt under locoregional anesthesia, in order to make this procedure more truly "minimally invasive". METHODS Demographic data, American Society of Anesthesiologists (ASA) score and vital signs, Ramsay sedation scale, and procedural duration were collected. All procedures were performed combining sedation with cervical plexus and scalp block. After internal jugular vein cannulation, a catheter was inserted and connected with a programmable valve and then with the ventricular catheter. Outcome was assessed by the Idiopathic Normal Pressure Hydrocephalus Grading Scale and complications were recorded at 3-month follow-up. RESULTS Ten consecutive patients were enrolled; the mean age was 74 years, 8 were male, ASA score median value was 3. Opioids were administered only in 4 patients, in 6 patients the value of Ramsay scale was 5. The average duration of surgery was 59.5 minutes. No procedure was converted to general anesthesia. CONCLUSIONS Our preliminary experience with ventriculoatrial shunt under locoregional anesthesia demonstrates that this technique is feasible, is not associated with an increase in operating times or complications, can avoid general anesthesia, and helps to limit opioid administration in the elderly. It can therefore represent a valid option in order to improve treatment quality in these complex patients.

Abstract
ABSTRACT Opioids in general and remifentanil in particular can induce hyperalgesia. Preclinical data suggest that cannabidiol might have the capacity to reduce opioid-induced hyperalgesia (OIH). Thus, we investigated the effect of oral cannabidiol on OIH in healthy volunteers using an established pain model. Twenty-four healthy participants were included in this randomized, double-blinded, crossover study and received either a 1600-mg single-dose oral cannabidiol or placebo. Hyperalgesia, allodynia, and pain were induced by intracutaneous electrical stimulation. To provoke OIH, participants recieved an infusion of 0.1 µg/kg/min remifentanil over a time frame of 30 minutes, starting 100 minutes after oral cannabidiol ingestion. The primary outcome was the area of hyperalgesia (in square centimetres) up to 60 minutes after remifentanil administration. The area of allodynia (in square centimetres) and pain (numeric rating scale) were also assessed.Cannabidiol had no significant effect on hyperalgesia, allodynia, or pain at any time point of measurement compared with placebo. The area of hyperalgesia after remifentanil administration significantly increased compared with baseline (17.0 cm 2 [8.1-28.7] vs 25.3 cm 2 [15.1-39.6]; P = 0.013). Mean cannabidiol blood levels were 4.1 ± 3.0 µg/L (mean ± SD) at 130 minutes after ingestion and were 8.2 μg/L ± 6.9 µg/L (mean ± SD) at 200 minutes. Cannabidiol was well tolerated. We conclude that a high single-oral dose of 1600-mg cannabidiol is not effective in reducing OIH. Before excluding an effect of cannabidiol on OIH, research should focus on drug formulations enabling higher cannabidiol concentrations.

Abstract
BACKGROUND Pain associated with surgical or enzymatic burn wound debridement prevents many burn centres from working outside an operating theatre, creating a burden. Alternatives for general anaesthesia to manage pain in burn patients treated with enzymatic debridements, such as regional anaesthesia, have not been studied in detail. This study explores the different possibilities for pain management during a bedside NexoBrid™ procedure. MATERIAL AND METHODS We performed a single-centre retrospective study that included 82 paediatric, adolescent, and adult patients with deep dermal and full-thickness burns treated bedside with NexoBrid™ under regional or general anaesthesia. Outcome measures were pain during the NexoBrid™ procedure, the safety of the anaesthesia and the NexoBrid™ procedure, logistics of the bedside NexoBrid™ procedure, and time to wound closure. RESULTS Forty-three patients in the adult group (43/67, 64%) only presented with burn wounds on one upper or the one or two lower extremities. In 29 of them (29/43, 67%), a NexoBrid™ procedure was performed under regional anaesthesia, which resulted in low pain levels without any adverse events. All seven patients in the paediatric group, where only one upper or one or two lower limbs were involved (7/15, 47%), underwent a NexoBrid™ procedure performed under regional anaesthesia where no adverse events were reported. In these children, the use of regional anaesthesia was associated with a significant decrease in time to wound closure (average treatment effect on the treated = -22.5 days, p = 0.021). CONCLUSION This study highlights that regional anaesthesia administered at the bedside should be the method of choice for pain management during NexoBrid™ procedures because often, it can be adequately and safely performed in all age groups. This approach will reduce the burden on operating theatres. A flow chart has been developed to guide pain management during a NexoBrid™ procedure.

Abstract
Postoperative pain is prevalent and often undertreated. There is a risk that untreated or suboptimally treated postoperative pain may transition into chronic postoperative pain, which can be challenging to treat. Clinical guidelines recommend the use of multimodal analgesia, including non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen, and, in some cases, opioids. NSAIDs are a broad class of drugs with different attributes such as cyclo-oxygenase (COX)-1 or COX-2 selectivity, onset of action, and analgesic potency. NSAIDs are associated with gastrointestinal and cardiovascular side effects and should be administered at the lowest effective dose for the shortest effective duration but can be effective in postoperative pain. The role of opioids in postoperative analgesia is long-standing but has recently come under scrutiny. Opioids are often used in multimodal analgesic combinations in such a way as to minimize the total consumption of opioids without sacrificing analgesic benefit. Special clinical considerations are required for surgical patients already on opioid regimens or with opioid use disorder. A particularly useful fixed-dose combination product for postoperative analgesia is dexketoprofen-tramadol, which confers safe and effective postoperative pain control and reduces the risk of persistent postoperative pain.

Abstract
BACKGROUND Opioid-based treatment is used to manage stress responses during surgery and postoperative pain. However, opioids have both acute and long-term side effects, calling for opioid-free anaesthetic strategies. This meta-analysis compares adverse events, postoperative recovery, discharge time from post-anaesthesia care unit, and postoperative pain, nausea, vomiting, and opioid consumption between strict opioid-free and opioid-based general anaesthesia. METHODS We conducted a systematic review and meta-analysis. We searched PubMed, Embase, Cinahl, Cochrane Library, selected reference lists, and Google Scholar. We included randomised controlled trials (RCTs) published between January 2000 and February 2021 with at least one opioid-free study arm, i.e. no opioids administered preoperatively, during anaesthesia induction, before skin closure, or before emergence from anaesthesia. RESULTS The study comprised 1934 patients from 26 RCTs. Common interventions included laparoscopic gynaecological surgery, upper gastrointestinal surgery, and breast surgery. There is firm evidence that opioid-free anaesthesia significantly reduced adverse postoperative events (OR 0.32, 95% CI 0.22 to 0.46, I2 = 56%, p < 0.00001), mainly driven by decreased nausea (OR 0.27, (0.17 to 0.42), p < 0.00001) and vomiting (OR 0.22 (0.11 to 0.41), p < 0.00001). Postoperative opioid consumption was significantly lower in the opioid-free group (-6.00 mg (-8.52 to -3.48), p < 0.00001). There was no significant difference in length of post-anaesthesia care unit stay and overall postoperative pain between groups. CONCLUSIONS Opioid-free anaesthesia can improve postoperative outcomes in several surgical settings without evidence of adverse effects on patient safety and pain management. There is a need for more evidence-based non-opioid anaesthetic protocols for different types of surgery as well as postoperative phases.

Combined opioid free and loco-regional anaesthesia enhances the quality of recovery in sleeve gastrectomy done under ERAS protocol: a randomized controlled trial. BMC Anesthesiol 2022; 22:29.

Abstract
Background It is debatable whether opioid-free anaesthesia (OFA) is better suited than multimodal analgesia (MMA) to achieve the goals of enhanced recovery after surgery (ERAS) in patients undergoing laparoscopic sleeve gastrectomy. Methods In all patients, anaesthesia was conducted with an i.v. induction with propofol (2 mg. kg-1), myorelaxation with cisatracurium (0.15 mg.kg-1), in addition to an ultrasound-guided bilateral oblique subcostal transverse abdominis plane block. In addition, patients in the OFA group (n = 51) received i.v. dexmedetomidine 0.1 μg.kg-1 and ketamine (0.5 mg. kg-1) at induction, then dexmedetomidine 0.5 μg. kg-1.h-1, ketamine 0.5 mg.kg-1.h-1, and lidocaine 1 mg. kg-1.h-1 for maintenance, while patients in the MMA group (n = 52) had only i.v. fentanyl (1 μg. kg-1) at induction. The primary outcome was the quality of recovery assessed by QoR-40, at the 6th and the 24th postoperative hour. Secondary outcomes were postoperative opioid consumption, time to ambulate, time to tolerate oral fluid, and time to readiness for discharge. Results At the 6th hour, the QoR-40 was higher in the OFA than in the MMA group (respective median [IQR] values: 180 [173–195] vs. 185 [173–191], p < 0.0001), but no longer difference was found at the 24th hour (median values = 191 in both groups). OFA also significantly reduced postoperative pain and morphine consumption (20 mg [1–21] vs. 10 mg [1–11], p = 0.005), as well as time to oral fluid tolerance (238 [151–346] vs. 175 min [98–275], p = 0.022), and readiness for discharge (505 [439–626] vs. 444 min [356–529], p = 0.001), but did not influence time to ambulate. Conclusion While regional anaesthesia achieved most of the intraoperative analgesia, avoiding intraoperative opioids with the help of this OFA protocol was able to improve several sensible parameters of postoperative functional recovery, thus improving our knowledge on the OFA effects.

Opioid Prescription Following Wrist and Ankle Fracture Fixation in Scotland—Tradition Prevails. J Clin Med 2022; 11:jcm11020468. [PMID: 35054162 PMCID: PMC8781195 DOI: 10.3390/jcm11020468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Revised: 12/22/2021] [Accepted: 01/10/2022] [Indexed: 12/10/2022] Open
Abstract
The American ‘opioid crisis’ is rapidly spreading internationally. Perioperative opioid use increases the risk of long-term opioid use. We review opioid use following wrist and ankle fracture fixation across Scotland, establishing prescribing patterns and associations with patient, injury, or perioperative factors. Six Scottish orthopedic units contributed. A total of 598 patients were included. Patient demographics were similar across all sites. There was variation in anesthetic practice, length of stay, and AO fracture type (p < 0.01). For wrist fractures, 85.6% of patients received a discharge opioid prescription; 5.0% contained a strong opioid. There was no significant variation across the six units in prescribing practice. For ankle fractures, 82.7% of patients received a discharge opioid prescription; 17% contained a strong opioid. Dundee and Edinburgh used more strong opioids; Inverness and Paisley gave the least opioids overall (p < 0.01). Younger patient age, location, and length of stay were independent predictors of increased prescription on binary regression. Despite variability in perioperative practices, discharge opioid analgesic prescription remains overwhelmingly consistent. We believe that the biggest influence lies with the prescriber-institutional ‘standard practice’. Education of these prescribing clinicians regarding the risk profile of opioids is key to reducing their use following surgery, thus lowering long-term opioid dependence.

Abstract
BACKGROUND Opioid-free anesthesia (OFA) is associated with significantly reduced cumulative postoperative morphine consumption in comparison with opioid-based anesthesia (OBA). Whether OFA is feasible and may improve outcomes in pancreatic surgery remains unclear. METHODS Perioperative data from 77 consecutive patients who underwent pancreatic resection were included and retrospectively reviewed. Patients received either an OBA with intraoperative remifentanil (n = 42) or an OFA (n = 35). OFA included a combination of continuous infusions of dexmedetomidine, lidocaine, and esketamine. In OBA, patients also received a single bolus of intrathecal morphine. All patients received intraoperative propofol, sevoflurane, dexamethasone, diclofenac, neuromuscular blockade. Postoperative pain management was achieved by continuous wound infiltration and patient-controlled morphine. The primary outcome was postoperative pain (Numerical Rating Scale, NRS). Opioid consumption within 48 h after extubation, length of stay, adverse events within 90 days, and 30-day mortality were included as secondary outcomes. Episodes of bradycardia and hypotension requiring rescue medication were considered as safety outcomes. RESULTS Compared to OBA, NRS (3 [2-4] vs 0 [0-2], P < 0.001) and opioid consumption (36 [24-52] vs 10 [2-24], P = 0.005) were both less in the OFA group. Length of stay was shorter by 4 days with OFA (14 [7-46] vs 10 [6-16], P < 0.001). OFA (P = 0.03), with postoperative pancreatic fistula (P = 0.0002) and delayed gastric emptying (P < 0.0001) were identified as only independent factors for length of stay. The comprehensive complication index (CCI) was the lowest with OFA (24.9 ± 25.5 vs 14.1 ± 23.4, P = 0.03). There were no differences in demographics, operative time, blood loss, bradycardia, vasopressors administration or time to extubation among groups. CONCLUSIONS In this series, OFA during pancreatic resection is feasible and independently associated with a better outcome, in particular pain outcomes. The lower rate of postoperative complications may justify future randomized trials to test the hypothesis that OFA may improve outcomes and shorten length of stay.

Abstract
PRACTICAL RELEVANCE Increases in cat ownership worldwide mean more cats are requiring veterinary care. Illness, trauma and surgery can result in acute pain, and effective management of pain is required for optimal feline welfare (ie, physical health and mental wellbeing). Validated pain assessment tools are available and pain management plans for the individual patient should incorporate pharmacological and non-pharmacological therapy. Preventive and multimodal analgesia, including local anaesthesia, are important principles of pain management, and the choice of analgesic drugs should take into account the type, severity and duration of pain, presence of comorbidities and avoidance of adverse effects. Nursing care, environmental modifications and cat friendly handling are likewise pivotal to the pain management plan, as is a team approach, involving the cat carer. CLINICAL CHALLENGES Pain has traditionally been under-recognised in cats. Pain assessment tools are not widely implemented, and signs of pain in this species may be subtle. The unique challenges of feline metabolism and comorbidities may lead to undertreatment of pain and the development of peripheral and central sensitisation. Lack of availability or experience with various analgesic drugs may compromise effective pain management. EVIDENCE BASE These Guidelines have been created by a panel of experts and the International Society of Feline Medicine (ISFM) based on the available literature and the authors' experience. They are aimed at general practitioners to assist in the assessment, prevention and management of acute pain in feline patients, and to provide a practical guide to selection and dosing of effective analgesic agents.

Abstract
Objectives: Opioid-free anesthesia is used increasingly often in hospitals around the world. In this type of anesthesia, opioids are replaced by other analgesics, such as ketamine, lidocaine, dexmedetomidine, and magnesium sulfate. Many clinicians prepare these agents as dual, triple, or quadruple admixtures within a single syringe. However, data on the stability of the individual substances within these preparations over time and in different storage conditions is very limited. Here, we aim to investigate various admixture of dexmedetomidine, ketamine, lidocaine, and magnesium sulfate with respect to the stability of the individual agents over time at different storage conditions. Methods: An ultra-high performance liquid chromatography method coupled to mass spectrometric detection was developed and validated to determine the stability of lidocaine, ketamine, and dexmedetomidine. Quantification of magnesium was carried out in parallel by potentiometric titration. Results: Our results demonstrate the stability of dual, triple or quadruple mixtures of selected substances in 0.9% saline under different storage conditions. Under all conditions, analyzed admixtures remain stable for at least 8 weeks. The quadruple mixture of lidocaine, ketamine, dexmedetomidine, and magnesium sulfate was storable for as long as 148 days without a significant loss of analyte. Conclusion: A new chromatographic method was successfully developed to analyze the stability of various pharmacological agents commonly used by clinicians in opioid-free anesthesia. The data we obtained indicate that mixing these agents together in a single syringe is safe and reliable and suggest that hospital pharmacies may prepare these solutions in advance of planned surgeries.

Abstract
Opioids form an important component of general anesthesia and perioperative analgesia. Discharge opioid prescriptions are identified as a contributor for persistent opioid use and diversion. In parallel, there is increased enthusiasm to advocate opioid-free strategies, which include a combination of known analgesics and adjuvants, many of which are in the form of continuous infusions. This article critically reviews perioperative opioid use, especially in view of opioid-sparing versus opioid-free strategies. The data indicate that opioid-free strategies, however noble in their cause, do not fully acknowledge the limitations and gaps within the existing evidence and clinical practice considerations. Moreover, they do not allow analgesic titration based on patient needs; are unclear about optimal components and their role in different surgical settings and perioperative phases; and do not serve to decrease the risk of persistent opioid use, thereby distracting us from optimizing pain and minimizing realistic long-term harms.

Effects of pupillary reflex dilation-guided opioid administration on remifentanil and morphine consumption during laparoscopic surgery: A randomised controlled trial. Eur J Anaesthesiol 2021; 38:975-984.

Abstract
BACKGROUND Analysis of pupillary reflex dilation (PRD) assesses the balance of nociception--antinociception. Laparoscopic surgery induces haemodynamic variations that are misleading. During laparoscopy, PRD guidance helps differentiate haemodynamic changes because of excess nociception from secondary changes related to the reflex release of endocrine factors. OBJECTIVE The present study evaluated the effect of PRD-guided antinociception on the administration of intra-operative remifentanil and immediate postoperative morphine consumption in patients undergoing elective laparoscopic surgery. DESIGN The study was a single-blind, randomised controlled trial. SETTING The study took place at two sites at the University Hospital of Nancy from March 2014 to November 2017. PATIENTS A total of 100 patients who underwent scheduled laparoscopic surgery were included. INTERVENTIONS Patients were randomly given remifentanil guided by PRD (PRD-guided) or standard anaesthesia care (control). MAIN OUTCOME MEASURES The primary outcome was intra-operative remifentanil consumption. Secondary outcomes included morphine consumption in the immediate postoperative period and the number of intra-operative haemodynamic events. RESULTS Data from 95 patients were analysed. Intraoperative remifentanil consumption was lower in the PRD-guided group than in the control group: median [IQR], 0.09 [0.07 to 0.11] vs. 0.14 [0.12 to 0.16] μg kg min, with a mean difference (95% confidence Interval, CI) of 0.048 (0.035 to 0.060) μg kg min; P < 0.0001. Morphine consumption was 0.13 [0.1 to 0.5] vs. 0.15 [0.11 to 0.4] mg kg (P = 0.52) in the PRD-guided and control groups, respectively. The number of hypertensive and tachycardia events was greater in the PRD-guided group than in the control group: Hypertensive events 60.4 vs. 32.6%, relative risk 1.85 (95% CI, 1.24 to 2.84), P = 0.004; tachycardia events 31.6% vs. 4.3%, relative risk 2.09 (95% CI, 1.45 to 2.84), P < 0.001. CONCLUSIONS When PRD is used to differentiate between haemodynamic events arising from noxious stimuli and those events because of other nonsurgical stimuli, then intra-operative remifentanil administration is reduced intra-operatively during laparoscopic surgery but there was no change in postoperative morphine consumption.

Abstract
Due to its potential benefits and increased patient satisfaction minimal invasive cardiac surgery (MICS) is rapidly gaining in popularity. These procedures are not without challenges and require careful planning, pre-operative patient assessment and excellent intraoperative communication. Assessment of patient suitability for MICS by a multi-disciplinary team during pre-operative workup is desirable. MICS requires additional skills that many might not consider to be part of the standard cardiac anesthetic toolkit. Anesthetists involved in MICS need not only be highly skilled in performing transesophageal echocardiography (TEE) but need to be proficient in multimodal analgesia, including locoregional or neuroaxial techniques. MICS procedures tend to cause more postoperative pain than standard median sternotomies do, and patients need analgesic management more in keeping with thoracic operations. Ultrasound guided peripheral regional anesthesia techniques like serratus anterior block can offer an advantage over neuroaxial techniques in patients on anti-platelet therapy or anticoagulation with low molecular weight or unfractionated heparin The article reviews the salient points pertaining to pre-operative assessment and suitability, intraoperative process and postoperative management of minimally invasive cardiac procedures in the operating theatre as well as the catheterization lab. Special emphasis is given to anesthetic management and analgesia techniques.

Abstract
INTRODUCTION Quadrantectomy is a surgical procedure traditionally performed under general anaesthesia with intraoperative and postoperative opioid-based analgesia. The use of locoregional anaesthesia techniques in breast surgery has become widespread and allows excellent management of intraoperative and postoperative pain with reduced opioid consumption. We chose thoracic paravertebral block as regional anaesthesia technique in breast surgery to investigate the possibility of carrying out this surgery with the patient awake. METHODS A prospective observational study on 50 patients was designed. The primary outcome for this study was the possibility to carry out the surgery with only the paravertebral block associated with mild sedation without general anaesthesia. Forty minutes before the start of the surgery, an ultrasound-guided thoracic paravertebral block was performed at two thoracic levels, and for each level, 7 mL of ropivacaine 0.7% was injected. Sedation was obtained with target-controlled infusion of propofol. RESULTS Forty-nine patients underwent the operation awake; in one case, we had to place an I-gel and perform general anaesthesia. No patient needed intraoperative or postoperative opioids. The numeric rating scale, recorded at 0, 2, 6, 12, 24, and 36 hours, was greater than 3 in only five patients. CONCLUSIONS We believe that if in the future we try to make quadrantectomy an intervention in which the anaesthesia is exclusively regional, therefore with a patient awake and collaborating, it will not be possible to ignore the use of thoracic paravertebral block.

Abstract
Children with sickle cell disease (SCD) require specific perioperative care, and clinical practice in this area remains poorly defined. We aimed to conduct a systematic, PRISMA-based review of the literature, available clinical guidelines and practice recommendations. We also aimed to extract any valuable information for the "best of available-evidence"-based prevention of perioperative adverse events in children with SCD, and highlight the most urgent priorities in clinical research. As data sources, US National Library of Medicine, Medline, National Guideline Clearinghouse, International Guideline Network, TRIP databases were searched for any content until January 2019. We also included institutional, consortia and expert group guidelines. Included were reports/guidelines in English, French, German, and Italian. Excluded were reports on obstetrical and fetal management. We identified 202 reports/guidelines fulfilling the criteria outlined above. A majority focused on visceral, cardiovascular and orthopedic surgery procedures, and only five were multicenter randomized controlled trials and two prospective randomized studies. After grading of the quality of the evidence, the extracted data was summarized into clinical recommendations for daily practice. Additionally, we designed a risk-grading algorithm to identify contexts likely to be associated with adverse outcomes. In conclusion, we provide a systematic PRISMA-based review of the existing literature and ancillary practice and delineate a set of clinical recommendations and priorities for research.

Abstract
OBJECTIVE To evaluate the perioperative opioid-sparing effect of a medetomidine (MED) infusion compared to a saline (SAL) infusion in otherwise healthy dogs undergoing thoraco-lumbar hemilaminectomy surgery. STUDY DESIGN Randomized, partially blinded, clinical study. ANIMALS A total of 44 client-owned adult dogs. METHODS All dogs were administered a 1 μg kg-1 MED loading dose, followed by a 1.7 μg kg-1 hour-1 constant rate infusion (CRI) intravenously or equivalent volumes of SAL. Infusions were started 10-15 minutes before surgical incision and continued throughout the surgical procedure. All dogs were administered a standardized anaesthetic and analgesic protocol (including a ketamine CRI). Multiparametric monitoring, including invasive arterial blood pressure, was performed. A trained investigator, unaware of the treatment, performed pain scores for 4 hours postoperatively. Rescue analgesia consisted of fentanyl administered intraoperatively and methadone postoperatively. Data were tested for normality and analysed with Fisher's exact test, Mann-Whitney U-test, analysis of variance and Kaplan-Meier survival analysis. Data are shown as median (interquartile range) and p-value was set at < 0.05. RESULTS The total dose of fentanyl was significantly lower with MED 0 (0-0.8) μg kg-1 hour-1 compared to SAL 3 (1.8-5.3) μg kg-1 hour-1 (p = 0.004). In the MED group, one dog compared to 12 dogs in the SAL group required a fentanyl CRI (p = 0.001). There were no statistically significant differences between groups regarding the total dose of methadone administered. CONCLUSIONS AND CLINICAL RELEVANCE The addition of a low-dose medetomidine CRI to the anaesthetic protocol decreased the need for a fentanyl CRI in otherwise healthy dogs undergoing thoraco-lumbar hemilaminectomy surgery during administration of a ketamine CRI.

Abstract
The epidemic of opioid crisis started getting recognised as a public health emergency in view of increasing opioid-related deaths occurring due to undetected respiratory depression. Prescribing opioids at discharge has become an independent risk factor for chronic opioid use, following which, prescription practices have undergone a radical change. A call to action has been voiced recently to end the opioid epidemic although with the pain practitioners still struggling to make opioids readily available. American Society of Anesthesiologist (ASA) has called for reducing patient exposure to opioids in the surgical setting. Opioid sparing strategies have emerged embracing loco-regional techniques and non-opioid based multimodal pain management whereas opioid free anesthesia is the combination of various opioid sparing strategies culminating in complete elimination of opioid usage. The movement away from opioid usage perioperatively is a massive but necessary shift in anesthesia which has rationalised perioperative opioid usage. Ideal way moving forward would be to adapt selective low opioid effective dosing which is both procedure and patient specific while reserving it as rescue analgesia, postoperatively. Many unknowns persist in the domain of immunologic effects of opioids, as complex interplay of factors gets associated during real time surgery towards outcome. At present it would be too premature to conclude upon opioid-induced immunosuppression from the existing evidence. Till evidence is established, there are no recommendations to change current clinical practice. At the same time, consideration for multimodal opioid sparing strategies should be initiated in each patient undergoing surgery.

Objective monitoring of nociception: a review of current commercial solutions. Br J Anaesth 2019; 123:e312-e321. [PMID: 31047645 DOI: 10.1016/j.bja.2019.03.024] [Citation(s) in RCA: 139] [Impact Index Per Article: 27.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 02/11/2019] [Accepted: 03/04/2019] [Indexed: 11/22/2022] Open
Abstract
Nociception, in contrast to pain, is not a subjective feeling, but the physiological encoding and processing of nociceptive stimuli. However, monitoring nociception remains a challenge in attempts to lower the incidence of acute postoperative pain and the move towards a more automated approach to analgesia and anaesthesia. To date, several commercialised devices promise a more accurate reflection of nociception than the traditionally used vital signs, blood pressure and heart rate. This narrative review presents an overview of existing technologies and commercially available devices, and offers a perspective for future research. Although firm conclusions about individual methods may be premature, none currently appears to offer a sufficiently broad applicability. Furthermore, there is currently no firm evidence for any clinically relevant influence of such devices on patient outcome. However, the available monitors have significantly aided the understanding of underlying mechanisms and identification of potential pitfalls.

Abstract
Background and Aims: Pectoral block (PECS)-based anesthesia without opioids decreases analgesic requirement, pain scores and post-operative nausea vomiting (PONV) compared to conventional opioid-based general anesthesia in patients undergoing modified radical mastectomy and axillary dissection (MRM-AD). We compared PECS versus Paravertebral Block (PVB) in providing an opioid free, nerve block-based regimen. Outcomes of interest were post-operative analgesic requirement, duration of analgesia, PONV and patient and surgeon satisfaction. Material and Methods: This randomised controlled study involved 58 adult ASA I-III patients posted for MRM-AD. After randomization patients were induced with propofol and maintained on spontaneous ventilation with isoflurane (0.8-1.0 MAC) through i-gel. Ultrasound-guided PECS or PV blocks (30 ml of 0.1% lignocaine + 0.25% bupivacaine + 1 μg/kg dexmedetomidine) were administered. Post-operative pain scores, non-opioid analgesic requirement over 24 hours, PONV, satisfaction of surgeon and patient were measured. Results: Between the two groups, there was no difference in demographics, ASA status, location and volume of breast tumour excised or the duration of surgery. The time from block to incision was significantly longer in the PV group (P = 0.01). There was no difference between the two groups in terms of intra and post-operative parameters, and the median VAS scores for pain at rest or during shoulder abduction were similarly low in both the groups. Conclusion: Both blocks result in equally prolonged analgesia and preclude requirement of opioid analgesics intra and post-operatively. PECS block is associated with lesser time to allow incision. Complications are low in both the groups. Routine use of these blocks to avoid opioids may be studied further.
