简要总结
This study is a prospective, randomized, parallel group trial comparing the efficacy of ultrasound assisted peripheral nerve stimulator guided versus peripheral nerve stimulator guided lumbosacral plexus block (LPSB) for postoperative analgesia in terms of patient satisfaction, time taken for the procedure, ease of administration, number of pricks, duration of analgesia, postoperative analgesic requirement and haemodynamic parameters associated with the procedure in patients undergoing elective unilateral lower limb surgery. The study will be conducted in Government Medical College, Amritsar on 60 ASA grade I-II patients of either sex in the age group of 20 to 60 years scheduled for lower limb orthopaedic surgery under spinal anaesthesia, randomly divided into two groups of 30 patients each- Group ’U’ will receive LSPB using ultrasound assisted peripheral nerve stimulator guided technique and Group ’P’ will receive LSPB using peripheral nerve stimulator guided technique. The data thus obtained will be analyzed and compared statistically.
