Filter by:Bleeding is one of the most common complications in tympanomastoid surgery that could prolong the time of operation and also might lead to morbidity. Pain is also one of the most annoying complications of tympanomastoid surgeries. Thus, adequate surgical field visualization is utmost important. A bloodless field allows optimal exposure and identification of vital neurovascular structures. Even small bleeding, inconsequential for the patient's volume status, can create great technical difficulty in the confined space of the tympan, leading to prolonged surgery, incomplete procedures, and increased complications. The use of regional nerve blocks as an alternative to hypotensive anesthesia has gained popularity in recent years. The superficial cervical plexus block (SCPB) provides effective analgesia and reduces sympathetic activity, resulting in reduced bleeding and improved surgical conditions. The superficial cervical plexus (SCP) provides sensory innervation to the ear and surrounding structures, reducing pain perception during and after surgery. This is the first randomized controlled clinical trial investigating the effect of combined general anesthesia with SCPB using 0.125% versus 0.25% bupivacaine during tympanomastoid surgery. This study aims to compare the efficacy of two different concentrations of bupivacaine 0.125% & 0.25% in Superficial Cervical Plexus Block in patients undergoing tympanomastoid surgery on operative field visualization, intraoperative hemodynamic stability, and postoperative analgesia. The investigators hypothesize that bupivacaine 0.125% would be non-inferior to bupivacaine 0.25% in achieving optimal surgical field visualization, hemodynamic stability, surgeon satisfaction and postoperative analgesia. This prospective double-blinded study will be carried out on 60 patients between 21 to 70 years, with ASA I-II and undergoing tympanomastoid surgery. Participants were equally divided into two groups: Group A: Patients received SCPB using 0.25% bupivacaine (5ml of bupivacaine 0.5% + 5ml normal saline). Group B: Patients received SCPB using 0.125% bupivacaine (2.5ml of bupivacaine 0.5% + 7.5ml normal saline).
Non-steroidal anti-inflammatory drugs (NSAID) are part the multimodal strategy in pain management after surgery. However, major concerns are raised in cardiac surgery given the potential side effects of NSAID with more bleeding and acute kidney injury. The investigators hypothesized that NSAID are safe in the early postoperative course after cardiac surgery with respect to contraindication.
Ultrasound-guided Modified Thoracoabdominal Nerve Plane Block (M-TAPA) is performed deep into the costochondral aspect at the 9th-10th costal level by injecting local anesthetics deep into the chondrium. It provides blockage of both the anterior and lateral cutaneous branches of the thoracoabdominal nerve. As there are studies showing M-TAPA block to be effective for postoperative analgesia for other abdominal surgeries, its effect on patients undergoing living liver donor surgery has not been studied yet. We hypothesize that M-TAPA block performed in living liver donors would reduce opioid consumption in the first 48 hours after surgery.
this study aim to Compare the effect of preoperative Epidural Midazolam, Morphine and their combination in postoperative pain relief and total morphine consumption.
