Active clinical trials for "Pain, Postoperative"

Colorectal cancers are one of the leading causes of cancer-related mortality, and the incidence is increasing day by day. For this reason, colorectal cancer surgery and postoperative analgesia have gained more importance in recent years.Although laparoscopic surgery is less invasive, it can still generate moderate to severe acute postoperative pain.For a long time, opioids have played a major role in postoperative analgesia, but heavy use of these drugs will cause adverse reactions such as nausea, vomiting and enteroparalysis, which is not conducive to rapid recovery after surgery Therefore, it is critical to developing a more effective regional analgesic technique for patients undergoing abdominal surgery . Erector spinae plane block (ESPB) is a novel interfascial plane block technique that was firstly described in 2016. It involves injecting local anesthetic into the plane between the deep fascia of the erector spinae muscle and the vertebral transverse process under ultrasound guidance to relieve pain in the thoracoabdominal region .The quadratus lumborum block (QLB) is a new posterior abdominal trunk block which produces analgesic effects through local anesthetic that covers thoracolumbar fascia and thoracic paravertebral space. Based on the injection position and approach, there are 3 QLB techniques: lateral approach, posterior approach and anterior approach. The anterior transmuscular quadratus lumborum block (TQLB) is a truncal block (ventral rami of T7- L2) that produces its analgesic effect by blocking the thoracic sympathetic trunk, the ventral rami of lower spinal nerves, the sympathetic fibers and mechanoreceptors within the thoracolumbar fascia, and the celiac ganglion by spread via the splanchnic nerves .

During general anesthesia, objective monitoring for analgesia is still lacking. The administration of opioids relies on the experience of the anesthesiologist. There are some monitors, e.g., Analgesia Nociception Index (ANI), showing that they can evaluate analgesia in adults. Recently, a Newborn Infant Parasympathetic Evaluation (NIPE) monitor was released for assessing analgesia in children with age less than 2 years. The investigators aim to assess the efficacy of NIPE as a guide for intraoperative fentanyl administration in children under 2 years.

The goal of root canal therapy is thorough disinfection and obturation of the root canal system in all its dimensions and promote periradicular tissue repair.This study was done to compare the postopertaive pain after single visit endodontics using resin based sealer and zinc oxide eugeonal sealer

This study is designed to test the efficacy of adding Depomedrol a long-acting steroid to bupivacaine for relieving postoperative pain and reducing opioid requirements following total knee replacement surgery. For this purpose, Depomedrol will be added to bupivacaine for ultrasound-guided Genicular nerve block combined with spinal anesthesia.

The goal of this clinical trial is to compare modified versus conventional thoracolumbar interfascial plane block for perioperative analgesia in lumber spine surgery. The main question it aims to answer is: • Whether modified thoracolumbar interfascial plane block is as effective as the conventional block for perioperative analgesia in lumber spine surgery. 60 patients were enrolled in the study, divided by simple random sampling into 3 groups.

Hip fracture is a common cause of surgery, especially in elderly patients. Unilateral spinal anesthesia in hip fracture surgery can prevent the undesirable effects of spinal anesthesia due to sympathetic blockade. However, severe pain in hip fracture patients limits the positioning required for unilateral spinal anesthesia. The sedation and analgesia required to position patients with fractured hip remains inferior may cause respiratory depression, hemodynamic instability or postoperative cognitive impairment, especially in elderly patients. Lower extremity peripheral blocks can be used preoperatively to minimize the use of sedatives that may be required during positioning and to provide effective and safe analgesia.

The purpose of this study is to evaluate effectiveness of a fixed combination of acetaminophen/naproxen sodium compared with placebo for reduction of pain when administered as multiple doses over a 48-hour period.

The goal of this clinical trial is to evaluate in effect of tap block and esp block on quality of recovery and postoperative pain after laparoscopic hysterectomy. The main question it aims to answer are: Are these two plane blocks used superior to each other? Participants; will fill out the preoperative questionnaire will fill out the postoperative questionnaire will report their pain status according to the NRS score

Approximately 120 subjects will be randomized into 1 of the following 2 treatment groups in a 1:1 ratio: Group 1: ZYNRELEF® up to 200 mg/ 6mg ( 7ml vial) via instillation at all incision sites in addition to 30 ml of 0.5% Ropivacaine + 10mg dexamethasone. Postoperatively, intermittent IV acetaminophen will be administered as per need till discharge. Group 2: 30 ml of 0.5% Ropivacaine and 10mg dexamethasone into all surgical sites and intermittent IV acetaminophen as per need till discharge. Primary Objective: To compare the efficacy and duration of analgesia achieved following the instillation of ZYNRELEF® all incision sites in addition to Ropivacaine with dexamethasone + postoperative IV acetaminophen, to the standard treatment of Ropivacaine with dexamethasone + postoperative IV acetaminophen in subjects undergoing laparoscopic sleeve gastrectomy. Secondary Objectives: To evaluate additional efficacy parameters, including opioid load, in this study population. To determine the impact of ZYNRELEF® on the cost of pain management. To assess the time taken to resume exercise after discharge. To assess the adverse events reported following the use of ZYNRELEF®.

Quadratus lumborum block (QLB) and Transversus abdominis plane (TAP) blocks are regional anesthesia techniques that are frequently used to reduce postoperative pain and are an important part of the current analgesic regimen for many abdominal surgeries. In our clinic, researchers perform both blocks to provide postoperative analgesia. The primary aim of our study is to compare the effectiveness of TAP block and QLB block in postoperative pain control in laparoscopic sleeve gastrectomy. Secondary outcomes evaluated in this study were to assess postoperative nausea and vomiting (PONV), time to discharge, and patient satisfaction.
