Filter by:The objective of this randomized controlled trial is to compare the analgesic efficacy and the safety profile between two techniques of injection for the interscalene block. The interscalene block consists of injecting local anesthetic around the cervical roots of the brachial plexus and allows analgesia after shoulder surgery. Stated differently, the dual objective of that study is: 1. to confirm that an injection at a distance of 4 mm away from the lateral sheath of the plexus (distal injection) provides similar analgesia as a classical injection within the plexus (subfascial injection); 2. to demonstrate that a distant extrafascial injection produces less respiratory complications than a subfascial injection, defined as hemidiaphragmatic paresis.
Study Hypothesis: The analgesic requirements and pain scores postoperatively differ between the epidural and continuous wound infusion techniques.
This study will evaluate the affects of a single injection ultrasound-guided adductor canal block for patients undergoing robotic-assisted (MAKOplasty) medial UKA (unicompartmental knee arthroplasty). Specifically, this study will compare the adequacy of postoperative analgesia provided by the adductor canal block with that provided by single injection lumbar plexus blockade. The working hypothesis is that the analgesia provided by the adductor canal block will be equivalent to the analgesia provided by the lumbar plexus block. The primary outcome will be a comparison of verbal numerical pain scores at rest and with movement over the first 24 hours following nerve blockade.
This study evaluates two anaesthetic techniques namely interscalene brachial plexus block and intra-articular local anaesthetic injection. Both techniques are currently used for providing postoperative pain relief following arthroscopic shoulder stabilisation operation. It will be a randomised controlled trial involving 30 patients in two groups.
The benefit of small doses of ketamine has been demonstrated for postoperative analgesia in adults but remains unproved in children. The investigators' purpose is to evaluate the effects of continuous intravenous small doses of ketamine versus placebo to improve the quality of postoperative analgesia in children (6 months to 6 years of age). Caudal anesthesia is performed for intraoperative analgesia and all children receive paracetamol, a non-steroidal anti-inflammatory and continuous intravenous nalbuphine.
