Active clinical trials for "Pain, Postoperative"

Using a randomized controlled design, the investigators goal is to estimate the effect of VR on postoperative analgesia and opioid consumption.

The investigators aim to investigate the effect of peritubal local anesthetic infiltration on pain scores and analgesic consumption in patients who underwent percutaneous nephrolithotomy.

The purpose of the study is to evaluate the effect of continuous pectoral nerve block on postoperative analgesia consumption in breast cancer surgery.

There will be two groups in this study: one group will be given the standard infusion of naloxone, a drug which helps reduce side effects from opioids needed after surgery, and the other group will receive a higher dose. The trial is designed to determine if a higher dose of naloxone infusion will reduce side effects from opioid therapy in patients who have undergone spine fusion for scoliosis.

The purpose of this study is to evaluate how effective is the preoperative administration of pregabalin 600mg, to attenuate postoperative pain and opioids consumption after laparoscopic cholecystectomy.

Objective: The authors hypothesized that combined deep and superficial serratus anterior plane block (SAPB) is as effective as erector spinae plane block (ESPB) for intraoperative and postoperative analgesia for video-assisted thoracoscopic surgery. Design: A prospective randomized controlled study. Participants: Adult patients undergoing elective video-assisted thoracoscopic surgery. Interventions: Preoperative SAPB or ESPB implementation.

Patients will be enrolled in one of the two groups using a computer-generated random number table: Group I will receive 2.5 ml of 0.5% hyperbaric bupivacaine (12.5 mg) . Group II will receive 1.5 mL of 0.5% hyperbaric bupivacaine (7.5 mg) along with 1 mL (5 μg )of dexmedetomidine (total 2.5 mL).

The aim of this study is to investigate the postoperative analgesic efficacy of SPSIPB and its effect on opioid consumption in patients undergoing video-assisted thoracoscopic surgery (VATS).

The aim of this study is to investigate the postoperative analgesic efficacy of SPSIPB and its effect on opioid consumption in patients undergoing reduction mammoplasty.

This prospective, randomized study,control study aims to compare the analgesic effect,opioids consumption,quality of recovery,length of hospital stay，et al. between single-injection QLB(quadratus lumborum block)+ intravenous patient-controlled analgesia (IPCA) and intravenous patient-controlled analgesia (IPCA) alone in patients undergoing laparoscopic partial nephrectomy.
