Filter by:The aim of this study is to compare the effects of intrathecal injection of hyperbaric bupivacaine versus injection of hyperbaric and isobaric bupivacaine in patients undergoing lower abdominal surgery.
the purpose of study is comparison between the analgesic effect of two techniques in adult lower abdominal surgeries
Caudal block (CB), a regional anesthesia technique, is the most commonly used neuraxial block method for postoperative pain control in sub-umbilical surgeries in children. However, peripheral nerve blocks have been reported to be preferred in recent years in the literature since they provide longer and safer analgesia. One of these blocks, the erector spina plane (ESP) block, has been shown to provide effective postoperative analgesia when administered from the lumbar level for sacral and lower abdominal surgeries and urogenital surgeries in pediatric patients.
This clinical trial is a prospective, multi-center, single-blind, parallel, randomized controlled superiority clinical trial. The trial will be carried out in 5 centers, involving 120 subjects as estimated who will be divided into the test group or control group randomly on an equal basis (each group includes 60 subjects). This trial will be carried out in 4 stages, including the screening period, random grouping, operation date and follow-up period. In the screening period, the informed consent forms are collected and candidates are screened; after screening, the accepted subjects will be randomly divided into the control group or test group; on the operation date, the operation is carried out using the device tested; safety follow-up visit is carried out during the follow-up period.
Brief summary: Regional anesthesia decreases the need for intravenous analgesia in the peri-operative period. Erector spinae plane (ESP) is a regional anesthesia technique shown to be effective at the dorsal and ventral rami of the thoracic spinal nerve along with sympathetic nerve fibers. The purpose is to demonstrate the contribution of ESP block to the postoperative analgesia by ultrasonography and to increase intraabdominal tissue oxygenation compared to the control group.
This study aims to explore the feasibility of using loss-of-resistance technique for Quadratus Lumborum block (QLB). And to compare between the Ultrasound guided QLB type II and the loss-of-resistance technique for QLB as regards the degree and duration of analgesia and side effects.
The transversus abdominis plane (TAP) block is a relatively simple technique that provides myocutaneous anesthesia that, as part of a multimodal analgesic treatment, may be useful in the prevention and treatment of parietal postoperative pain. Initial experience with ultrasound TAP block demonstrated efficacy of the echo guided technique in different surgical procedures such as cesarean section, appendicectomy, laparoscopic cholecystectomy, infra umbilical surgery in adult and pediatric patients. Recently published clinical trials suggest that TAP block may represents an effective alternative to epidural anesthesia but further studies in larger population are necessary. Transversus-abdominis plane (TAP) block was found to increase analgesic consumption low thoracic-epidural analgesia (TEA) in ischemic heart disease patients after abdominal laparotomy (2). Others found comparable results between continuous transversus abdominis plane technique and epidural analgesia in regard to pain, analgesic use and satisfaction after abdominal surgery(3). The TAP block affords effective analgesia with opioid sparing effects, technical simplicity, and long duration of action. Some disadvantages include the need for bilateral block for midline incisions and absence of effectiveness for visceral pain (4). TAP block has been associated with good pain relief and decreased intraoperative and postoperative opioids requirements after laparoscopic surgery (5). The analgesic efficacy of the TAP block has been demonstrated in prospective randomized trials compared with placebo, in different surgical procedures such as abdominal surgery, hysterectomy, retro pubic prostatectomy, Caesarean section, laparoscopic cholecystectomy, and appendicectomy (6, 7, 8, 9, 5 and 10 respectively). All these studies have reported superiority of the TAP block in terms of reduction in visual analogue scale scores and morphine consumption. In this study the investigators try to compare Transversus Abdominis Plane (TAP) blocks versus caudal block for postoperative pain control after lower abdominal surgeries in pediatrics.
