A DOSE-RESPONSE STUDY COMPARING TWO DOSAGES OF HYPOBARIC BUPIVACAINE (WITH FENTANYL 25 MCG) FOR UNILATERAL SPINAL AN ANAESTHESIA IN HIP FRACTURE SURGERY. A RANDOMIZED DOUBLE BLIND PROSPECTIVE COMPARATIVE STUDY OF 5 MG VERSUS 7.5 MG.

Abstract

Hip joint fractures are associated with perioperative hypotension and myocardial ischemia. These patients have significant rates of coronary artery disease. This study compares the time it takes for hypobaric bupivacaine (5 mg) and bupivacaine (7.5 mg) to stop the movement of muscles during surgery for a hip fracture with bromage.ULSA or another anesthetic was used if unilateral spinal anaesthesia failed recuperation. The Aldrete and Bromage Scales were modified to aid recovery. S2 sensory block and a bromage score of 0 prompted admission. The ward recorded post-operative analgesia, rescue, and side symptoms such as nausea, vomiting, pruritus, headache, urine retention, etc. Postoperative rescue analgesia was paracetamol (1 g i.v) if the VAS was more than 4. No postoperative nausea, vomiting, or urine retention Unilateral spinal anaesthesia with 5 mg of hypobaric Bupivacaine is as effective as 7.5 mg but has fewer side effects and more stable blood pressure. Low-dose Bupivacaine-induced unilateral spinal anaesthesia helps stabilize hemodynamics.
