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

Abstract

General and regional anaesthesia are possible for hip joint fractures, but subarachnoid block (spinal anaesthesia) is most usual. This study compares the sensory block onset and duration of hypobaric bupivacaine (5 mg and 7.5 mg) in unilateral spinal anaesthesia for hip fracture surgery.ULSA or another anesthetic was given if unilateral spinal anaesthesia failed. Recuperation. Modified Aldrete and Bromage Scales helped patients recover. Patients were admitted after S2 sensory block and bromage score restored to 0. The ward recorded post-operative analgesia, rescue, and side effects such nausea, vomiting, pruritus, headache, urine retention, and others. If the VAS was greater than 4, paracetamol (1 g i.v) was given as the initial rescue analgesic postoperatively. Post-operative nausea, vomiting, and urine retention were absent. Unilateral spinal anaesthesia with 5 mg of hypobaric Bupivacaine is just as effective as 7.5 mg, but has fewer side effects and more stable blood pressure. Unilateral spinal anaesthesia can give hemodynamic stability due to a lower sympathetic block with low Bupivacaine dosages.
