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.
To gain a clearer understanding of the association between frailty and postoperative acute pain in elderly thoracoscopic surgery patients and its underlying mechanisms, to provide new solution ideas to reduce the level of postoperative acute pain and improve the debilitating state of elderly thoracoscopic surgery patients, and consequently improve their quality of life and mental status.
Cryoneurolysis is a regional anaesthetic technique that works by freezing peripheral sensory nerves. This technique can potentially provide analgesia after total knee arthroplasty (TKA). However, the technique is expensive and comprehensive. Pain 24 hours after surgery is associated with high amounts of late acute pain. Therefore, the aim of the current study was to compare the effect of postoperative cryoanalgesia with a sham treatment on acute postoperative pain in TKA patients with moderate to severe pain on the first postoperative day. The cryoanalgesia treatment will be performed 24 hours after surgery. Afterward, the patients will be followed for 24 weeks to determine the level of pain among other outcomes.
Immersive virtual reality (VR) as a non-pharmaceutical technology may deliver effective behavioral therapies for postsurgical patients with acute pain. To determine the analgesic effects of VR on patients after thoracoscopic surgery. The investigators conducted a randomized clinical trial to determine the postoperative effect of VR on pain relief in patients undergoing thoracoscopic surgery.
This study will use group-based trajectory modeling to identify the different postoperative pain trajectory groups that exist in a mixed surgical population (non-cardiac surgery) of elderly patients during the first seven days after surgery. The aim of this study is to explore the diversity in the development of postoperative pain among elderly patients and to identify the risk factors for acute pain trajectory after surgery by investigating demographic, psychological, and clinical variables. The predictive effect of different trajectories of early postoperative acute pain on postoperative chronic pain will also be explored.
Postoperative pain is a common manifestation in orthopedic patients, mainly due to intraoperative tissue damage and inadequate intraoperative pain assessment and management .Axillary brachial plexus block provides motor and sensory block with the distribution of the median, radial, ulnar and musculocutaneous branches so can be conducted with upper limb orthopedic surgery in hand, rest and elbow surgery distal to the cubital fossa . In this study the investigators will investigate (0.19%) and (0.25%) bupivacaine for postoperative motor power recovery and post-operative analgesic efficacy in ultrasound guided axillary brachial plexus block among pediatric patient undergoing below elbow orthopedic surgery.
To investigate the effect of ultrasound-guided thoracic paravertebral nerve block on postoperative acute and chronic pain and cognitive function in elderly patients with thoracoscopic partial lung resection.
Major lumbar spine surgeries are associated with severe postoperative pain that usually lasts for at least 3 days.Caudal epidural analgesia has a crucial role in providing effective pain relief post lumbar spine surgeries by blocking sensory input at the level of the spinal cord. Erector Spinae Plane Block (ESPB) as a new technique of trunk fascia block was proposed in 2016Reports showed that ESPB significantly relieved postoperative pain in patients with lumbosacral spine surgery, reducing the use of analgesics. The aim of this work is to evaluate the pre-emptive analgesic effect of Ultrasound guided bilateral erector spinae block Vs Caudal epidural analgesia in Lumbar spine surgeries during peri-operative period. Objectives: - To assess the duration of analgesia in both groups and time to rescue analgesia . - To assess Visual analogue scale (VAS) score in both groups. - To assess complications of both groups
