A Comparative Study Of 0.5% Levobupivacaine And 0.5% Bupivacaine In Spinal Anaesthesia In Geriatric Patients Undergoing Lower Limb Surgeries

Abstract

Introduction: The geriatric population faces serious problems. When combined with the tendency for older population to have more unsteady balance and vision problems, it becomes a recipe for increased risk of fracture. Hemodynamic stability during peri-operative period is of paramount importance in such scenario and hence the technique of choice becomes neuraxial block to maintain hemodynamic stability namely heart rate, saturation, blood pressure and by avoiding hypotension, bradycardia etc. Key Words: Geriatric, Lower limb surgeries, Spinal anesthesia Aim: To compare the efficacy of 0.5% Bupivacaine and 0.5% Levobupivacaine in geriatric patients with regard to- 1. Time of onset of sensory blockade and maximum level of sensory blockade 2. Time to grade 4 motor blockade and time to 2 segment regression 3. Time to rescue analgesia, hemodynamic changes (RR,SPO2,MAP,HR) and side effects if any Methods: A comparative study was conducted in the department of Anesthesia at _____ _____________________ Medical College Hospital and Research Centre, _______________. Ethical Committee permission- Taken Informed written consent- Takengeratric patients (above 60 years) scheduled for lower limb surgeries under spinal anesthesia divided into two groups. Group B (BUPIVACAINE) 0.5 % hyperbaric Inj. Bupivacaine 3ml to 60 patients Group L (LEVOBUPIVACAINE) 0.5 % hyperbaric Inj. Levobupivacaine 3ml to 60 patients Test used were chi square test and unpaired t test. Inclusion criteria : 1. Patients age group above 60 years. 2. Patients with ASA grade II and III. 3. Patients undergoing elective lower limb surgeries. Exclusion criteria : 1. Patients having deformities of spine. 2. Patients having infection at the site of insertion of spinal needle. 3. Patients having bleeding disorders, coagulation abnormalities, raised Intra cranial pressure (ICP) and neurological deficits. etc.
