Filter by:In recent years, suprainguinal fascia iliaca block (SFIB) has emerged as a reliable analgesic option for primary total hip arthroplasty (THA). In 2018, a new block was described, termed pericapsular nerve group block or PENG block, that selectively targets the articular branches of the femoral and obturator nerves while sparing their motor components. In this randomized trial, the investigators will compare US-guided SFIB and PENG block in patients undergoing primary THA. Since the main benefit of PENGB stems from its quadriceps-sparing effect, it was selected the incidence of quadriceps motor block (at 6 hours) as the primary outcome and the hypothesis that PENG block will result in significantly less motor block compared to SFIB.
Transversus abdominis plane (TAP) block can be used to provide effective analgesia during the postoperative period following a range of surgeries. TAP block administers local anesthetics between the T6 to L1 spinal nerve roots to stop the nerve signal and to alleviate pain for abdominal procedures 4, 5. The viscera are innervated by the vagal nerve (parasympathetic innervation) and by the splanchnic nerves (sympathetic innervation). The splanchnic nerves carry both visceral efferent and afferent nerve fibers. The sensory (or afferent) part of the splanchnic nerves reach the spinal column at certain spinal segments, It is possible to block central visceral pain conduction with thoracic paravertebral blockade or maybe even with the novel quadratus lumborum (QL) block. The effect of the QL block is believed to result from a spread of LA from its lumbar deposition cranially into the thoracic paravertebral space (TPVS), since Carney et al found traces of contrast agent in the TPVS following application of this block. Hence, the QL block would seem to be able to alleviate both somatic and visceral pain.10 The aim of this study is to compare between quadratus lumborum block, transversus abdominis plane block regarding perioperative analgesia after bladder cancer surgeries by measuring intraoperative hemodynamics, postoperative pain scores and morphine consumption in the first 24 h postoperative.
This study showed the difference in postoperative pain between the groups that performed surgery with the low-pressure pneumoperitoneum and the group that performed surgery in the standard-pressure pneumoperitoneum when robotic single-hole cholecystectomy was performed. The primary purpose of the study was to compare the differences in the visual analog scale (VAS) between the two groups and to demonstrate the effectiveness of pain relief after surgery. Secondly, the effect of the low-pressure pneumoperitoneum on the patient's postoperative recovery and outcome was compared with the control group by comparing the length of stay, operation time, and postoperative complications.
Suprascapular nerve block (SSNB) is most commonly used for relieving postoperative pain of arthroscopic rotator cuff repair and it can be used in combination with axillary nerve block (ANB). Dexmedetomidine (DEX) is known as a type of alpha agonist which can elongate the duration of regional block. The aim of this study was to compare the results of dexmedetomidine combined with SSNB and ANB with SSNB and ANB alone on postoperative pain, satisfaction, and pain-related cytokines within the first 48 hours after arthroscopic rotator cuff repair. Forty patients with rotator cuff tears who had undergone arthroscopic rotator cuff repair were enrolled in this single center, double-blinded randomized controlled trial study. Twenty patients were randomly allocated to group 1 and received ultrasound-guided SSNB and ANB using each mixture of 0.5 ml (50 μg) of DEX and 9.5 ml of 0.75% ropivacaine preemptively. The other 20 patients were allocated to group 2 and underwent ultrasound-guided SSNB and ANB alone using a mixture of 0.5 ml of normal saline and 9.5 ml of ropivacaine. The visual analog scale (VAS) for pain and patient satisfaction (SAT) scores were checked within 48 h postoperatively. The plasma interleukin (IL)-6, -8,-1β, cortisol, and serotonin levels were also measured within 48 h postoperatively.
Arthroscopic shoulder surgery is often associated with moderate to severe postoperative pain that may interfere with patients' early mobilization, recovery and quality of life. In addition, by using an effective analgesic technique, a patient may experience less nausea, vomiting and drowsiness after surgery that are associated with the use of opioids to manage postoperative pain. Erector spinae plane block (ESPB) has been used in many different indications for acute pain treatment at different thoracic and lumbar levels. Recently, staining the roots of the brachial plexus has been reported in a cadaveric study of the cervical ESPB (1). However, there are only few case reports related to efficiency and safety of this newly defined cervical ESPB technique (2) . The primary objective of this randomized controlled is investigate the post-operative analgesic effectiveness of ultrasound guided single-shot cervical ESPB for patients undergoing arthroscopic shoulder surgery in comparison to those receiving conventional parentheral opioid analgesia alone. Secondary objective is testing the safety of this newly defined block in terms of incidence of complications.
This is a prospective randomized double blind controlled study to evaluate the post-operative analgesic effect of adductor canal block (ACB) or peri-articular injection (PAIs) compared to combined adductor canal block and infiltration of the interspace between popliteal artery and the capsule of posterior knee block ( IPACK) in patient undergoing total knee arthroplasty
Aim of the work To evaluate the efficacy of ultrasound-guided erector spinae plane block for management of postoperative pain in patients undergoing major abdominal surgery under general anesthesia. Hypothesis - Null hypothesis: The investigators suppose that ultrasound-guided erector spinae plane block has no post-operative analgesic effect in patients undergoing major abdominal surgery. - Alternative hypothesis: The investigators suppose that ultrasound-guided erector spinae plane block has post-operative analgesic effect in patients undergoing major abdominal surgery. Study objectives Primary Objective: Comparison of opioid consumption in patients receiving erector spinae plane block in relation to control group. Secondary Objective: 1. Evaluate the hemodynamics (blood pressure, heart rate) and respiratory rate in patients receiving erector spinae plane block during postoperative period at 0, 2, 4, 6, 8, 12,24 hours. 2. Assessment of numeric rating scale (NRS) in patients receiving erector spinae plane block during rest and movement during postoperative period at 0, 2, 4, 6, 8, 12,24 hours.
This prospective randomized controlled double-blind study will be carried out to evaluate the effect of ultrasound-guided erector spinae plane block on the postoperative analgesia in children after hip surgeries, the total morphine consumption in the first postoperative day will be the primary outcome and the time to first request for rescue analgesia and postoperative pain score will be the secondary outcome. The study will be carried out on pediatric patients undergoing hip surgery where they will receive real or sham ultrasound guided erector spinae plane block before the onset of the surgery.
Surgical repair of the hip can be extremely painful and is associated with considerable postoperative pain in children despite the use of systemic opioids. These patients may benefit from neuraxial analgesia in adjunction with general anesthesia. The reported advantages of this technique include decreased opiate exposure, decreased time in the post-anesthesia recovery room, decreased hospital stay, reduce the post-operative morbidity, provide early mobilization. Regional anesthetic techniques seem to be a better choice for improving acute pain management in these patients, with fewer adverse effects.
Thoracic epidural and paravertebral blocks are the most widely regional technique used for postoperative analgesia after surgery, but they are difficult to perform and carry a risk of serious complication. In this study, investigator asses the efficacy of ultrasound ESPB on intraoperative and postoperative hemodynamics and patient satisfaction
