A RANDOMIZED PROSPECTIVE OBSERVATIONAL STUDY COMPARING SPINAL VERSUS CAUDAL EPIDURAL ANAESTHESIA IN THE MANAGEMENT OF PATIENTS UNDERGOING AMBULATORY PERIANAL SURGERY.

Abstract

Background & Methods: The aim of the study is to compare spinal versus caudal Epidural
Anaesthesia in the management of patients undergoing ambulatory perianal surgery.All
subjects received 2 L/min of nasal oxygen during the whole procedure. A > 30 % decrease in
MAP from the baseline measurement or a drop in systolic blood pressure < 90 mmHg was
defined as hypotension. 5-10 mg intravenous ephedrine was administered in case of
Intraoperative hypotension. Heart rate < 50 beats/min was defined as bradycardia. 0.6 mg
intravenous atropine was administered to manage intraoperative bradycardia.
