Active clinical trials for "Pain, Postoperative"

A majority of patients would suffer from moderate-to-severe postoperative pain after undergoing craniotomy. As a result, adequate pain control is essential for patients' prognosis and their postoperative life quality. Although opioids administration is regarded as the first-line analgesic for post-craniotomy pain management, it may be associated with delayed awakening, respiratory depression, hypercarbia and it may interfere with the neurologic examination. For the avoidance of side-effects of systemic opioids, local anesthetics administered around the incision have been performed clinically. However, some studies revealed that the analgesic effect of local anesthetics was not unsatisfactory due to its short pain relief duration. As is reported that postoperative pain of craniotomy is mainly caused by skin incision and reflection of muscles, preventing the liberation of inflammatory mediators around the incision seems to be more effective than simply blocking nerve conduction. Thus, Investigators suppose that pre-emptive scalp infiltration with steroid (dexamethasone) plus local anesthetic (ropivacaine) could relieve postoperative pain after craniotomy in adults.

The purpose of this study is to determine whether amitryptyline is effective in the prevention of pain in women after a total abdominal hysterectomy.

The aim of this study is to compare between two regional analgesic techniques; caudal block and ultrasound guided quadratus lumborum block as regard degree of pain relief, accuracy of block, effect on hemodynamic stability and incidence of complications.

The aim of this study was to assess the analgesic efficacy of bilateral erector spinae plane block in comparison with intrathecal morphine after elective cesarean section under spinal anesthesia.

The TAP block, first described by Rafi in 2001, is comprised of deposition of a local anesthetic into the anatomical plane between the internal oblique and transverses abdominis muscles, where thess thoracoabdominal nerves (T6-L1) contribute to the main sensory supply of the skin, muscles, and parietal peritoneum of the anterior abdominal wall. These nerves branch and communicate extensively with each other in the TAP . Erector spinae plane (ESP) block is a recently described interfascial block in which the local anaesthectic is placed over or below the plane of the erector spinae muscle, near where the spinal nerves come out from the spine before they start to divide. Some publications have shown its effectiveness in treating thoracic and abdominal postoperative pain. Postoperative pain is the major obstacle for early postoperative ambulation and increases the risk of venous thromboembolism, respiratory complications and prolongs the hospital stay. Parietal pain is the chief component of postoperative pain after abdominal surgeries. Large doses of opioids are required to mitigate this pain, but they are poorly tolerated. Multimodal analgesia is effective in handling postoperative pain and in attenuating the side effects of large doses of a single analgesic .

Prospective randomized study of 150 patients qualified for knee arthroplasty between 2015 and 2017. Patients were randomized into 3 groups receiving vitamin D and calcium supplementation, increased protein supply and preoperative rehabilitation, respectively. Following factors were analyzed: changes in vitamin D3, calcium, total protein, albumin and CRP levels during preparation for surgery, nutritional status on the Subjective Global Assessment (SGA) scale, osteoporosis risk assessment according to the Osteoporosis Risk SCORE, level of pain felt on the scale VAS and the number of analgesics used, the result of the Duke Activity Status Index, the result of the following scales: Cardiac Risk Index for Orthopedic Surgery (Lee), Knee injury and Osteoarthritis Outcome Score (KOOS), Fear Avoidance Beliefs Questionnaire (FABQ) about Physical Activity, The Quality of Life Scale (QOLS). Additionally, the occurrence of perioperative complications was analyzed (e.g. venous thrombosis and pulmonary embolism, wound or joint infection, excessive bleeding, loosening of the implant, bone fracture or fracture, pain).

Recommendation is strong on physical activity (PA) in the prehabilitation of Enhanced Recovery After Surgery (ERAS) for various types of surgeries. The evidence is however weak regarding ERAS protocols. Many studies have showed that physical exercise and PA have hypoalgesic effects on healthy individuals and they have better pain tolerance too. Here the investigators study changes in postoperative pain and postoperative nausea and vomiting for various types of surgical patients after performing preoperative PA at moderate or vigorous intensity Vs non-preoperative PA patients.

Since its first description by Forero et al. there have been many articles and case reports including an increasingly number of indications for the ESP block: chronic and acute pain treatment, rib fractures management in the emergency setting, treatment of abdominal surgical pain, hip arthroplasty , analgesic management in breast surgery,or in spinal surgery.Although ESP block successfully reduced postoperative opioid consumption in clinical reports, no studies thus have investigated the optimum volume of bupivacaine for ESP block as regard a review of the medical literature on December 27th, 2017 that searched terms in 14 articles clearly stated the volume of the bolus and the spread of the anesthetic after an injection of LA, the volume needed to cover one dermatome widely varies from 2.5 mL to 6.6 mL, with a median value of 3.4 mL. Furthermore, the maximum number of dermatomes reached by a single bolus in ESP was of 9 dermatomes after a 30 mL bolus. Thus, in this study, the investigators evaluate the effect of ESP block which will be performed by using three different volumes (2.5, 3.4 ,6.6 ml/segment) of bupivacaine with the same concentration ,technique ,site of injection and operation.

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

This study will help us in understanding the role of erector spinae block (ESPB) for postoperative pain control in patients undergoing upper GI laparoscopy surgeries. The surgeries included in this group include laparoscopic cholecystectomy, laparoscopic gastrectomy, laparoscopic umblical or epigastric hernia repair. Patients aged between 18 and 65 years, scheduled to undergo any upper GI laparoscopy surgeries with an ASA score of 1 or 2 will be included in the study. This is a prospective randomised controlled trial which will compare two groups receiving either erector spinae block or no block for postoperative pain control after upper GI laparoscopy surgeries
