Abstract
Background: Continuous Spinal Anesthesia (CSA) is an underused regional anesthesia technique. But with the increased Geriatric population presenting to surgeries, CSA with its relative hemodynamic stability is coming back to anesthetists’ interests. Better control of hemodynamics is advantageous in elderly patients and those with cardiac diseases. Objective: To compare the incidence of hypotension in continuous spinal anesthesia CSA versus single dose spinal anesthesia SDA in octogenarians undergoing hip surgery, the total use of Ephedrine and the incidence of spinal complications. Methods: Forty (40) patients were enrolled in the study and allocated into two groups 20 patients in continuous spinal anesthesia group (CSA) and 20 patients in single dose anesthesia group (SDA). Results: CSA has less effect on hemodynamics in elderly patients with fewer complications. There was a statistically significant difference in MAP between CSA group and SDA group between min 5 & min 40 with p-value
