Before And After

Background A controversy exists over the effectiveness and clinical value of preemptive analgesia. Additional studies are needed to define the optimum intensity, duration, and timing of analgesia relative to incision and surgery. Methods One hundred twenty patients undergoing laparoscopic cholecystectomy under general anesthesia plus topical peritoneal local anesthetic or saline were studied. Local anesthetic (0.5% bupivacaine with epinephrine) or placebo solutions were given as follows: immediately after the creation of a pneumoperitoneum (blocking before surgery), and at the end of the operation (blocking after surgery). Patients were randomly assigned to one of four groups of 30 patients each. Group A (placebo) received 20 ml 0.9% saline both before and after surgery, group B received 20 ml 0.9% saline before surgery and 20 ml local anesthetic after surgery, group C received 20 ml local anesthetic both before and after surgery, group P received 20 ml local anesthetic before and 20 ml 0.9% saline after surgery. Pain was assessed using a visual analog scale and a verbal rating scale at 0, 4, 8, 12, and 24 h after surgery. Metabolic endocrine responses (blood glucose and cortisol concentrations) and analgesic requirements also were investigated. Results Pain intensity (visual analog and verbal rating scales) and analgesic requirements were significantly less in the group receiving bupivacaine after surgery compared to placebo. However, in the groups receiving bupivacaine before surgery, both pain intensity and analgesic consumption were less than in the group receiving bupivacaine only after surgery. Blood glucose and cortisol concentrations 3 h after surgery were significantly less in groups receiving bupivacaine before surgery. Conclusions The results indicate that intraperitoneal local anesthetic blockade administered before or after surgery preempts postoperative pain relative to an untreated placebo-control condition. However, the timing of administration is also important in that postoperative pain intensity and analgesic consumption are both lower among patients treated with local anesthetic before versus after surgery.

Background: The main goal of the present randomized clinical trial was to investigate the effects of subcutaneous administration of two different local anesthetics at trocar incision sites at the abdominal wall in combination with intraoperative intraperitoneal instillation of local anesthetics, on the character of postoperative pain, in adolescents who underwent laparoscopic varicocelectomy. Methods: A total of 60 patients with a median age of 16 years, who received laparoscopic varicocele repair, were included in this randomized clinical trial. The patients were randomly assigned to three study groups receiving 2% lidocaine, 0.5% levobupivacaine, or the control group. The Visual Analogue Scale (VAS) was used by a blinded nurse at four different time points (2, 6, 12 and 24 h after the surgery) to measure pain intensity. Results: The significant effect of time on the pain intensity (p = 0.001) was found. Additionally, the interaction between time and different local analgesics (p < 0.001) was observed. In patients in whom 0.5% levobupivacaine has been used, significantly lower VAS pain scores were recorded at each time point assessed, in comparison with the patients who received 2% lidocaine or the patients from the control group in whom no local anesthetic was applied (p < 0.001). Furthermore, in patients in whom 2% lidocaine was administrated, significantly lower pain levels according to VAS were reported than in those from the control group, except for the time point at 24 h after surgery when pain levels were comparable. Concerning the postoperative pain control, the number of patients who requested oral analgesics postoperatively was significantly lower in the group of patients in whom local anesthetic was administrated intraoperatively (2% lidocaine – n = 4, 20%; 0.5% levobupivacaine – n = 1, 5%) compared to the patients who did not receive any local anesthetic during the surgery (n = 13; 65%) (p < 0.001). Conclusion: A significant reduction in postoperative pain intensity and analgesics consumption in patients undergoing laparoscopic varicocelectomy who received intraoperative local anesthetic was observed. The best effect on postoperative pain intensity, according to the VAS score, was achieved by 0.5% levobupivacaine.

Compared with the open approach, laparoscopy has been shown to significantly reduce postoperative pain. Improving postoperative analgesia in laparoscopic surgery is an area of continued interest. The goal of this study was to compare the efficacy of local anesthetic infiltration with or without preoperative nonsteroidal anti-inflammatory drugs. Patients undergoing elective laparoscopic cholecystectomy were enrolled in an Institutional Review Board-approved, prospective, double-blinded, randomized, placebo-controlled comparison study. Patients were randomized into four groups: Group I, preoperative oral administration of a placebo medication and prein cision local infiltration of 40 mL of 0.5 per cent bupivicaine at trocar sites; Group II, preoperative oral administration of 50 mg of rofecoxib; Group III, preoperative oral administration of 50 mg of rofecoxib and preincision local infiltration of 40 mL of 0.5 per cent bupivicaine into skin, muscle, and peritoneum; and Group IV, preoperative oral administration of a placebo medication. Postoperative pain scores were assessed at 4 hours, 8 hours, 12 hours, and 24 hours using a visual analog scale. Postoperative analgesic use, complications, and length of stay were recorded. Statistical significance was defined as P < 0.05. Fifty-five patients (46 women and 9 men) were enrolled in this study and underwent a standardized, elective, laparoscopic cholecystectomy for mild, symptomatic cholelithiasis (96.4%) and gallbladder polyps (3.6%). No patient had pain immediately before surgery. Postoperative analgesic requests, visual analog scale results, incidence of postoperative vomiting at 4 hours, 8 hours, 12 hours, and 24 hours, in addition to length of stay, were not statistically different between the four groups. No complications occurred. The use of preoperative rofecoxib, 0.5 per cent bupivicaine infiltration, or both for postoperative analgesia did not decrease postoperative pain or decrease length of stay after laparoscopic cholecystectomy compared with placebo. Preoperative administration of an oral anti-inflammatory pain medication, infiltration of a local anesthetic, or both had no greater effect than placebo in controlling discomfort after a laparoscopic cholecystectomy. The challenge of preempting postoperative pain continues and will require further investigation.

BackgroundEpidural waveform analysis (EWA) provides a simple confirmatory adjunct for loss of resistance (LOR): when the needle/catheter tip is correctly positioned inside the epidural space, pressure measurement results in a pulsatile waveform. Epidural waveform analysis can be carried out through the tip of the needle (EWA-N) or the catheter (EWA-C). In this randomized trial, we compared the two methods. We hypothesized that, compared with EWA-C, EWA-N would result in a shorter performance time.MethodsOne hundred and twenty patients undergoing thoracic epidural blocks for thoracic or abdominal surgery were randomized to EWA-N or EWA-C. In the EWA-N group, LOR was confirmed by connecting the epidural needle to a pressure transducer. After obtaining a satisfactory waveform, the epidural catheter was advanced 5 cm beyond the needle tip. In the EWA-C group, the epidural catheter was first advanced 5 cm beyond the needle tip after the occurrence of LOR. Subsequently, the catheter was connected to the pressure transducer to detect the presence of waveforms. In both study groups, the block procedure was repeated at different intervertebral levels until positive waveforms could be obtained (through the needle or catheter as per the allocation) or until a predefined maximum of three intervertebral levels had been reached. Subsequently, the operator administered a 4 mL test dose of lidocaine 2% with epinephrine 5 µg/mL through the catheter. An investigator present during the performance of the block recorded the performance time (defined as the temporal interval between skin infiltration and local anesthetic administration through the epidural catheter). Fifteen minutes after the test dose, a blinded investigator assessed the patient for sensory block to ice. Success was defined as a bilateral block in at least two dermatomes. Furthermore, postoperative pain scores, local anesthetic consumption, and breakthrough analgesic consumption were recorded.ResultsNo intergroup differences were found in terms of performance time, success rate, postoperative pain, local anesthetic requirement, and breakthrough analgesic consumption.ConclusionEWA can be carried out through the needle or through the catheter with similar efficiency (performance time) and efficacy (success rate, postoperative analgesia).Trial registration numberNCT03603574.

Abstract Purpose Currently available local anesthetics have not demonstrated sufficient analgesia beyond 12–24 h postoperatively. The purpose of the study was to assess the safety and efficacy of HTX-011 (bupivacaine and meloxicam in Biochronomer® polymer technology), a long-acting investigational anesthetic, in reducing both postoperative pain over 72 h and postoperative opioid use compared to bupivacaine hydrochloride (HCl). Methods A phase 3, randomized, double-blind, active-controlled multi-center study (EPOCH 2; NCT03237481) in subjects undergoing unilateral open inguinal herniorrhaphy with mesh placement was performed. Subjects randomly received a single intraoperative dose of HTX-011, immediate-release bupivacaine HCl, or saline placebo prior to closure. Results The study evaluated 418 subjects, and the primary and all key secondary efficacy endpoints were in favor of HTX-011. HTX-011 reduced mean pain intensity by 23% versus placebo (primary endpoint; p < 0.001) and by 21% versus bupivacaine HCl (p < 0.001) with significant reductions in the number of patients experiencing severe pain. Opioid consumption over 72 h was reduced by 38% versus placebo (p < 0.001) and 25% versus bupivacaine HCl (p = 0.024). Overall, 51% of HTX-011 subjects were opioid-free through 72 h (versus 22% for placebo [p < 0.001] and 40% for bupivacaine HCl [p = 0.049]). HTX-011 was generally well-tolerated with fewer opioid-related adverse events reported compared to the bupivacaine HCl and placebo and no evidence of local anesthetic systemic toxicity. Conclusions HTX-011 demonstrated significant improvement in postoperative pain control and a clinically meaningful reduction in opioid consumption when compared to the most widely used local anesthetic, bupivacaine HCl.

Aim: HTX-011 (ZYNRELEF™) is an extended-release, dual-acting local anesthetic containing bupivacaine and meloxicam. In bunionectomy and herniorrhaphy studies, HTX-011 resulted in less postoperative pain and less opioid consumption versus bupivacaine HCl. Here we evaluate HTX-011 in patients aged ≥65 years. Materials & methods: Patients received placebo, bupivacaine HCl or HTX-011 following surgery. End points included pain intensity, total opioid consumption, opioid-free patients and safety. Results: HTX-011-treated patients reported lower postoperative pain through 72 h versus bupivacaine HCl and placebo. Elderly patients administered HTX-011 used fewer opioids versus bupivacaine HCl, and a greater proportion remained opioid-free through 72 h. HTX-011 was well tolerated with a safety profile similar to bupivacaine HCl and placebo. Conclusion: HTX-011 maintained effectiveness and was well tolerated in elderly patients.
