The Study Isobaric 0.75% Ropivacaine 3.5ml (26.25mg) Intrathecally for Lower Limb Surgeries to Evaluate Perioperative Hemodynamic Stability
Evaluation of Perioperative Hemodynamic Stability
Background: The purpose of the study is Isobaric 0.75% Ropivacaine 3.5ml (26.25mg) Intrathecally for Lower Limb Surgeries to Evaluate Perioperative Hemodynamic. Fifty patients admitted to our hospital undergoing lower extremity surgeries under spinal anesthesia. Subjects and Methods: Pre-anesthetic assessment was done prior to the day of surgery which included past history of chronic illness and medication, drug therapy (especially corticosteroids, anti hypertensive, anti coagulant, anti diabetic, anti convulsant medications), drug sensitivity and past anesthetic experience along with routine investigations including, haemoglobin, random blood sugar, serum urea, serum creatinine, and serum electrolytes, chest X-ray, ECG. Fifty patients admitted to our hospital undergoing lower extremity surgeries under spinal anesthesia included in the study. Results: Patients in the age group 18 – 60 years were selected including 45 males and 5 females. Thirty-Nine patients had an ASA grade I and 11 patients had an ASA grade II. The duration of surgeries ranged from 45 to 270 minutes & there were no significant changes in the pulse rate perioperatively. Conclusion: A study was conducted in 50 patients belonging to ASA grade I and II posted for lower limb surgeries. They received 3.5ml of 0.75% isobaric Ropivacaine in L2-3 interspace. All patients were preloaded with 1000 ml of ringer lactate. Following institution of subarachoid block sensory characteristics such as onset of sensory block, maximum level achieved, duration of sensory block and request for first dose of rescue analgesics were studied. We found the requirement for postoperative analgesics was 218.97 minutes. Hemodynamic parameters were stable in most of the patients. Postoperative side effects included shivering, nausea. Thus we conclude that isobaric 0.75% ropivacaine 26.25 mg, 3.5 ml when administered intrathecally in L2-3 interspace provides an adequate sensory block for lower limb surgeries, which makes it a good choice for lower limb surgeries with benefits of early ambulation.
