The Difference

Currently most of the anesthetist prefer the usage of multimodal analgesia technique to improve the degree of pain relief without inducing any side effects. Pregabalin and gabapentin when given in higher doses reduces the preoperative anxiety and induce sedation without causing undesirable side effects.To compare and evaluate the effects of premedication drugs Pregabalin or Gabapentin versus placebo for attenuation of postoperative pain among patients undergoing laparoscopic cholecystectomy under general anaesthesia.A prospective comparative study was conducted for a period of 6 months in the department of anesthesiology of our medical college hospital. A total of 90 patients posted for elective laproscopic cholecystectomy in the age group between 20 and 60 years were taken as our study subjects. The entire study subjects were randomized into three groups of 30 each. Group B subjects received 3 tablets of Beplex forte (as placebo), Group G subjects received 3 tablets of Gabapentin 300mg (total 900mg) and Group P subjects received 3 tablets of Pregabalin 50mg (total 150mg). Post-operatively degree of pain, requirement for rescue analgesia, sedation score and adverse events occurred was monitored and analysed between the three groups. Pain score was less in the pregabalin group at all intervals compared to gabapentin and placebo group and the difference was found to be statistically significant. Maximum amount of tramadol requirement as a part of rescue analgesia was seen in the placebo group followed by gabapentin group and minimal dose requirement was needed for pregabalin group and the difference was found to be statistically significant. The occurrence of adverse events such as somnolence and dizziness was almost similar in all the three groups whereas the incidence of nausea and vomiting was less in pregabalin group compared to gabapentin and placebo group. Pregabalin can be effectively used as a part of the multimodal analgesic to prevent acute postoperative pain among patients undergoing elective laproscopic cholecystectomy.

Abstract Background: Unrelieved postoperative pain afflicts millions each year in low and middle income countries (LMIC). Despite substantial advances in the study of pain, this area remains neglected. Current systematic review was designed to ascertain the types of clinical trials conducted in LMIC on postoperative pain management modalities over the last decade. Methods: A comprehensive search was performed in June 2019 on PubMed, Cochrane Library, CINAHL Plus, and Web of Science databases to identify relevant trials on the management of postoperative pain in LMIC. Out of 1450 RCTs, 108 studies were reviewed for quality evidence using structured form of critical appraisal skill program. Total of 51 clinical trials were included after applying inclusion/exclusion criteria. Results: Results are charted according to the type of surgery. Eleven trials on laparoscopic cholecystectomy used multimodal analgesia including some form of regional analgesia. Different analgesic modalities were studied in 4 trials on thoracotomy, but none used multimodal approach. In 11 trials on laparotomy, multimodal analgesia was employed along with the studied modalities. In 2 trials on hysterectomy, preemptive pregabalin or gabapentin were used for reduction in rescue analgesia. In 13 trials on breast surgical procedures and 10 on orthopaedic surgery, multimodal analgesia was used with some form of regional analgesia. Conclusion: We found that over the past 10 years, clinical trials for postoperative pain modalities have evolved in LMIC according to the current postoperative pain management guidelines i.e. multi-modal approach with some form of regional analgesia. The current review shows that clinical trials were conducted using multimodal analgesia including but not limited to some form of regional analgesia for postoperative pain in LMIC however this research snapshot (of only three countries) may not exactly reflect the clinical practices in all 47 countries.

Objectives: This study’s objective was to determine whether multimodal analgesia plus an injection of the hamstring sheath immediately following the harvest of the semitendinosus and gracilis tendons during hamstring autograft anterior cruciate ligament reconstruction (ACLR) reduces postoperative pain. We hypothesized that multimodal analgesia plus a hamstring sheath injection of the harvest site for autograft hamstring ACLR reduces postoperative pain. Methods: The Institutional Review Board approved this study registered with ClinicalTrials.gov and identified by NCT01868425. This study was a single-center, surgeon stratified double-blind, placebo-controlled, randomized study from April 2013 to December 2017. Patients were randomly assigned to one of two groups, in a 1:1 ratio per surgeon, to receive either standard of care analgesia plus intra-operative hamstring sheath saline injection (Placebo group) or standard of care analgesia plus multimodal analgesia plus intraoperative hamstring sheath anesthetic injection (MA group) for patients undergoing ACLR with hamstring autograft. Eligible participants were adults aged 18 years to 55 years old consented for ACLR using hamstring tendon autograft. Contraindication to a femoral nerve block, allergy to protocol medications, nervous system disease, renal or hepatic impairment, history of opioid dependence or current narcotic use, significant psychiatric disease, pregnancy or lactating, a seizure disorder, history of postoperative nausea and vomiting, latex allergy, and clinically significant cardiac or pulmonary disease excluded patients for participation in this study. The primary endpoint was total postoperative opioid administration. Secondary endpoints included the patient’s subjective pain score for the posterior, anterior, and lateral side of the knee, postoperative nausea, sedation, and pruritus scores. Based on our preliminary data, we estimated the mean opioid for standard care will be 6.6 morphine equivalents with a standard deviation of 6.2 morphine equivalents. Testing the ability of multimodal analgesia to reduce opioid usage by at least 50%, a minimal sample size of 45 subjects per group was needed to achieve 80% power based on a one-tailed t-test and a significance level < 0.05. Student’s t-test compared outcomes between groups. Additionally, a linear regression model for was also used for the primary outcome with total opioid administration as the dependent variable in order to control for body mass index (BMI) and sex, providing an adjusted estimate of the difference between groups. Results: A total of 112 patients (Figure 1) met inclusion criteria and were randomized into the placebo group (n = 57) and MA group (n = 55). Demographic data demonstrated no significant differences between groups (Table 1). The primary analysis was postoperative opioid administration and included all patients randomly assigned to either group for opioid administration in the postoperative anesthetic care unit (PACU), however opioid administration in 24 hours after discharge was not recorded for five patients in the MA group, leaving 50 patients remaining for the per-protocol analyses. Secondary outcome data was not recorded for one patient in the placebo group leaving 56 patients remaining for the per-protocol analyses. The mean postoperative opioid needs (Table 2) for patients in the MA group (18.7 ± 13.14) was less than those in the placebo group (22.6 ± 11.15), although this was not statistically significant (p-value = 0.140). Secondary outcomes (Figure 2A) demonstrated a significant reduction in posterior knee pain postoperatively in the MA group (2.84 ± 2.25) compared to Placebo (3.56 ± 1.97; p-value = 0.0362). There were no significant differences in postoperative pain in the front or sides of the knee. Similarly, there were no significant differences in pruritis (MA: 0.26 ± 0.99 vs. Placebo: 0.696 ± 1.73; p-value = 0.2163), sedation (MA: 5.02 ± 2.29 vs. Placebo: 4.61 ± 2.16; p-value = 0.656), and nausea (MA: 1.16 ± 2.28 vs Placebo: 0.714 ± 1.72; p-value = 0.243) scores (Figure 2B). Conclusions: Multimodal analgesia plus hamstring sheath injection reduces postoperative patient reported posterior knee pain compared to placebo for patients undergoing ACLR using hamstring tendon autograft. However, multimodal analgesia plus a hamstring sheath injection does not reduce postoperative opioid requirements.

Abstract Background: There is still debate as to whether opioid-free anaesthsia (OFA) may offer additional benefit over multimodal analgesia to better achieve the goals of ERAS(Enhanced recovery after surgery) in bariatric surgery.Patients and method: Patients in the OFA group (n=51) were pre-medicated with IV dexmedetomidine 0.1 µg.kg-1 then induced with propofol (2 mg. kg-1) -ketamine (0.5 mg. kg-1) mixture and maintained on dexmedetomidine 0.5µg. kg-1.h-1, ketamine 0.5 mg.kg-1.h-1, and lidocaine 1 mg. kg-1.h-1. Patients in the MMA(Multimodal analgesia) group (n= 52) were induced using IV propofol 2 mg. kg-1, and fentanyl 1 µg. kg-1. Cisatracurium (0.15 mg.kg-1) was given to all patients for muscle relaxation. Ultrasound-guided bilateral oblique subcostal transverse abdominis plane (OSTAP) block was performed in all patients. The postoperative quality of recovery at 6 and 24 hours was measured as a primary outcome. Postoperative pain control; subsequent opioid consumption; time to ambulate; time to tolerate oral fluid; and time to readiness for discharge were measured as secondary outcomes Results: The total QoR-40 (quality of recovery-40) scores at 6 hours were significantly higher in the OFA group (184.84 versus 180.69 in the MMA group with an estimated difference in mean of -4.15, 95% CI, -5.78 to -2.5, and P ˂0.001. The OFA group tolerated oral fluid intake earlier (194.94, 95% CI, 162.59 to 227.30) versus (273, 95% CI, 223.65 to 322.27) for the MMA group (p value=0.009). Readiness for discharge was significantly quicker in the OFA group (447.49, 95% CI, 409.69 to 485.29 versus 544.56, 95% CI, 503.08 to 586.04 in the MMA group, P-value =0.001). The post-anesthesia care unit (PACU) (0 Hour) and the floor 2 and 6-hour numerical rating scales (NRS) for pain were significantly higher in the MMA group. The OFA group needed less opioid rescue analgesia in the PACU and at 24-hours (P value= 0.003 and 0.014; respectively).Conclusion: Combined Opioid free and loco-regional anesthesia provides better early recovery with reduced postoperative pain intensity, and opioid consumption when compared to multimodal analgesia; and is better suited to achieve the goals of ERAS protocol.Clinical trial number: registration number NCT04285255.

Background: The most common surgical procedure for breast cancer is the modified radical mastectomy (MRM), but it is associated with significant postoperative pain. Regional anesthesia can reduce the stress response associated with surgical trauma. Objectives: Our aim is to explore the efficacy of 1 µg/kg dexmedetomedine added to an ultrasound (US)-modified pectoral (Pecs) block on postoperative pain and stress response in patients undergoing MRM. Study Design: A randomized, double-blind, prospective study. Setting: An academic medical center. Methods: Sixty patients with American Society of Anesthesiologists (ASA) physical status I– II (18–60 years old and weighing 50–90 kg) scheduled for MRM were enrolled and randomly assigned into 2 groups (30 in each) to receive a preoperative US Pecs block with 30 mL of 0.25% bupivacaine only (group 1, bupivacaine group [GB]) or 30 mL of 0.25% bupivacaine plus 1 µg/ kg dexmedetomidine (group II, dexmedetomidine group [GD]). The patients were followed-up 48 hours postoperatively for vital signs (heart rate [HR], noninvasive blood pressure [NIBP], respiratory rate [RR], and oxygen saturation [Sao2]), visual analog scale (VAS) scores, time to first request of rescue analgesia, total morphine consumption, and side effects. Serum levels of cortisol and prolactin were assessed at baseline and at 1 and 24 hours postoperatively. Results: A significant reduction in the intraoperative HR, systolic blood pressure (SBP), and diastolic blood pressure (DBP) starting at 30 minutes until 120 minutes in the GD group compared to the GB group (P < 0.05) was observed. The VAS scores showed a statistically significant reduction in the GD group compared to the GB group, which started immediately up until 12 hours postoperatively (P < 0.05). There was a delayed time to first request of analgesia in the GD group (25.4 ± 16.4 hrs) compared to the GB group (17 ± 12 hrs) (P = 0.029), and there was a significant decrease of the total amount of morphine consumption in the GD group (9 + 3.6 mg) compared to the GB group (12 + 3.6 mg) (P = 0.001). There was a significant reduction in the mean serum cortisol and prolactin levels at 1 and 24 hours postoperative in the GD patients compared to the GB patients (P < 0.05). Limitations: This study was limited by its sample size. Conclusion: The addition of 1 µg/kg dexmedetomidine to an US-modified Pecs block has superior analgesia and more attenuation to stress hormone levels without serious side effects, compared to a regular Pecs block in patients who underwent MRM.

Abstract Introduction Pregabalin has been used for treatment of chronic pain, but recently it has been introduced in treatment of acute postoperative pain. Aim of Study This study is conducted to evaluate the postoperative analgesic effect of paracetamol and pregabalin combination versus paracetamol after hip surgeries. Methods The study was done on 20 randomly chosen patients after approval of the medical ethical committee of Ain Shams University. Patients were divided randomly into two groups, each group consisted of 10 patients.After preoperative assessment and obtaining baseline vital data all patients received spinal anaesthesia. Group I received paracetamol 1gm intravenous immediately postoperatively and every 6 hours for 24 hours. Group II received the same as group I plus two doses of oral pregabalin 300mg in the recovery room and 12 hours later. The two groups were assessed postoperatively and they were compared regarding demographic data, postoperative pain control, sedation, total pethidine consumption, hemodynamics and side effects. Results In pregabalin group (group II), pain scores and total pethidine consumption were significantly lower and sedation scores were higher than group II. Heart rate and arterial blood pressure were lower in group II but without clinical significance. Conclusions This study revealed that combination of paracetamol and pregabalin as multimodal analgesia is better than paracetamol alone in postoperative analgesia, and decreasing use of opioids without significant effect on hemodynamics but with increased incidence of side effects such as somnolence, dizziness and blurred vision.

Background Morphine-6-glucuronide (M-6-G), a major metabolite of morphine, is reported to be more potent than morphine when administered intrathecally; however, its efficiency remains under debate when administered intravenously. This study was designed to assess the analgesic efficiency of intravenous M-6-G for the treatment of acute postoperative pain. Methods After informed consent was obtained, 37 adults (American Society of Anesthesiologists physical status I-II) who were scheduled for elective open knee surgery were enrolled in the study. General anesthesia was induced with thiopental, alfentanil, and vecuronium and was maintained with a mixture of nitrous oxide/isoflurane and bolus doses of alfentanil. At skin closure, patients were randomized into three groups: (1) morphine group (n = 13), which received morphine 0.15 mg/kg; (2) M-6-G group (n = 12), which received M-6-G 0.1 mg/kg; and (3) placebo group (n = 12), which received saline. At the time of extubation, plasma concentration of morphine and M-6-G was measured. Postoperative analgesic efficiency was assessed by the cumulative dose of morphine delivered by patient-controlled analgesia. Opioid-related side effects were also evaluated. Results No difference was noted in patient characteristics and opioid-related side effects. Morphine requirements (mean +/- SD) during the first 24 h in the M-6-G group (41+/-9 mg) and the placebo group (49+/-8 mg) were significantly greater (P&lt;0.05) compared with the morphine group (29+/-8 mg). Conclusion A single intravenous bolus dose of M-6-G was found to be ineffective in the treatment of acute postoperative pain. This might be related to the low permeability of the blood-brain barrier for M-6-G.

Managing pain in the patient with substance use disorder can be challenging. This chapter describes those challenges and provides strategies to address them. Specifically it discusses the prevalence and specific considerations for commonly abused substances, the need for aggressive communication among perioperative clinicians, and a strategy to decrease acute postoperative pain and associated complications using opioid-sparing, multimodal analgesia. It includes a discussion of the concept of equianalgesic opioid doses and management of opioid-related side effects including respiratory depression, with regard to buprenorphine, naltrexone, and methadone. Specific consideration is given to the surgical patient treated with buprenorphine, and a defined clinical plan is outlined.

BackgroundMultimodal analgesia is a fundamental part of modern surgery and enhanced recovery pathways. Duloxetine, a serotonin and norepinephrine reuptake inhibitor, has been validated for the treatment of chronic neuropathic pain. The evidence for duloxetine as an adjunct for the treatment of acute postoperative pain remains controversial. We conducted a meta-analysis to determine the efficacy of duloxetine in the acute perioperative setting.MethodsA literature search was conducted in the major databases (PubMed, EMBASE and Google Scholar) for randomized controlled trials (RCTs) evaluating duloxetine compared with placebo control for acute postoperative pain. The primary outcome was postoperative pain assessed at 2, 4, 6, 24 and 48 hours time frames. Secondary outcomes included postoperative opioid administration, as well as side effects, such as postoperative nausea/vomiting (PONV), pruritus, dizziness and headache.Results574 patients (n=9 RCTs) were included in the analysis, divided between duloxetine (n=285 patients) and placebo (n=289 patients). Duloxetine use was associated with a significant reduction in pain scores as early as 4 (mean difference (MD) −0.9, 95% CI −1.33 to −0.47) and as late as 48 (MD −0.94, 95% CI −1.56 to −0.33) hours postoperatively compared with placebo. In addition, duloxetine was associated with a significant reduction in opioid administration at 24 (standardized MD (SMD) −2.24, 95% CI −4.28 to −0.19) and 48 (SMD −2.21, 95% CI −4.13 to −0.28) hours as well as a significant reduction in PONV (risk ratio 0.69, 95% CI 0.49 to 0.95, p=0.03) compared with placebo. There was no difference between groups in other side effects.ConclusionDuloxetine, a non-opioid neuromodulator, may provide efficacy for the treatment of acute perioperative pain. Additional prospective studies are required to establish optimal perioperative dosing regimens, role in the setting of a comprehensive multimodal analgesic plan and impact on chronic postsurgical pain.PROSPERO registration numberCRD42019121416

Background and Objectives: Acute postoperative pain is one of the most undesirable experiences for a patient in the postoperative period. Many options are available for the treatment of postoperative pain. One of the methods of multimodal analgesia is a combination of opioids and adjuvant agents, such as ketamine. The aim of this study was to evaluate the effect of a pre-incisional single injection of low-dose ketamine on postoperative pain after remifentanil infusion in patients undergoing laparoscopic gastric bypass or gastric plication surgery. Materials and Methods: The prospective, randomized, double-blinded and placebo-controlled trial took place at the Hospital of the Lithuanian University of Health sciences KaunoKlinikos in 2015–2017. A total of 32 bariatric patients (9 men and 23 women) were randomly assigned to receive a single pre-incisional injection of ketamine (0.15 mg/kg (LBM)) (ketamine, K group) or saline (placebo, S group). Standardized protocol of anesthesia and postoperative pain management was followed for all patients. Postoperative pain intensity, postoperative morphine requirements, incidence of side effects and patients’ satisfaction with postoperative analgesia were recorded. Results: Thirty-two patients undergoing bariatric surgery: 18 (56.25%; gastric bypass) and 14 (43.75%; gastric plication) were examined. Both groups did not differ in demographic values, duration of surgery and anesthesia and intraoperative drug consumption. Postoperative pain scores were similar in both groups (p = 0.105–0.941). Morphine consumption was 10.0 (7.0–12.5 mg) in group S and 9.0 (3.0–15.0 mg) in group K (p = 0.022). The incidence of side effects was similar in both groups (p = 0.412). Both groups demonstrated very high satisfaction with postoperative analgesia. Conclusions: Pre-incisional single dose ketamine reduces postoperative opioids consumption, but does not have an effect of postoperative pain intensity and side effects after remifentanil infusions. Very high patient satisfaction is achieved if standard multimodal analgesia protocol with an individual assessment of pain and dosage of medications is followed.

Introduction. Pain is the commonest morbidity after open surgical procedures. The most effective treatment of postoperative pain is opioid therapy. Morphine, the commonly used opioid, is associated with many side effects including respiratory depression, sedation, postoperative nausea vomiting, and pruritus. Nalbuphine, on the other hand, is known to cause less respiratory depression. Thus this study was undertaken to compare the intraoperative and postoperative analgesic efficacy and side effect profile of the two drugs. Methodology. 60 patients undergoing open gynaecological surgery were randomized to receive either morphine (Group M) or nalbuphine (Group N) in the intraoperative and postoperative period. Intraoperative analgesic efficacy (measured by need for rescue analgesics), postoperative pain by visual analogue scale, and side effects like postoperative nausea, vomiting, sedation, respiratory depression, and pruritus were compared in both groups. Intraoperative and postoperative heart rate and blood pressure were also compared between the groups. Results. Need for intraoperative analgesia was significantly more in Group N (P=0.023). Postoperative VAS scores were significantly different between the groups at various time points; however, none of the patients required any rescue analgesia. The incidence of various side effects was not significantly different between the groups. The haemodynamic profile of patients was comparable between the groups in both intraoperative and postoperative period. Conclusion. Nalbuphine provides less effective intraoperative analgesia than morphine in patients undergoing open gynaecological surgery under general anaesthesia. Both drugs, however, provided similar postoperative analgesia and had similar haemodynamic and side effect profile.
