Filter by:Hip fracture is a common cause of surgery, especially in elderly patients. Unilateral spinal anesthesia in hip fracture surgery can prevent the undesirable effects of spinal anesthesia due to sympathetic blockade. However, severe pain in hip fracture patients limits the positioning required for unilateral spinal anesthesia. The sedation and analgesia required to position patients with fractured hip remains inferior may cause respiratory depression, hemodynamic instability or postoperative cognitive impairment, especially in elderly patients. Lower extremity peripheral blocks can be used preoperatively to minimize the use of sedatives that may be required during positioning and to provide effective and safe analgesia.
Morphine, when given as part of spinal anesthesia, is associated high incidence of nausea and pruritus, which may affect quality of recovery. The investigators hypothesize that long-acting local anesthetic infusions via TAP catheter can provide better quality of recovery after cesarean section than spinal morphine.
Pain relief after open inguinal hernia repair could be improved by administration of TAP block or ilioinguinal/iliohypogastric nerve block. It is unclear which one works better. The investigators hypothesize that doing TAP block closer to the middle of the abdomen would result in improved pain relief due to simultaneous block of ilioinguinal/iliohypogastric nerves.
