Effect of preoperative multimedia based video information on perioperative anxiety and hemodynamic stability in patients undergoing surgery under spinal anesthesia

Pre-anesthesia checkup (PAC) gives unique opportunity for providing necessary information, patient education and allaying anxiety. Our objective was to measure the effect of preoperative multimedia video information (self made short video of 12 minutes) on patient's anxiety and hemodynamic parameters during surgery under spinal anesthesia.This prospective randomized study was conducted in 80 patients of either sex with ASA physical status I and II posted for lower limb surgery under spinal anesthesia. Patents were randomized to control or test group. At the end of preoperative visit, patients in test group watched the film and patient in control group did not watch any video. Verbal briefing by the attending anesthesiologist on the day of surgery was given to all patients of both the groups. Anxiety using Amsterdam Preoperative Anxiety and Information Scale (APAIS) and hemodynamic parameters (SBP, DBP and HR) at various time intervals (A1: Baseline, A2: post intervention, A3: just before surgery, A4: after surgery) were measured.Baseline anxiety (A1) scores were severe in both the groups and showed no statistical significance (P = 0.436). Patients in test group (video) showed better/lower anxiety levels than the control group (non video) at A2 (P = 0.020) and A3 (P = 0.005) respectively, similarly hemodynamic parameters were better controlled and showed lesser deviation from baseline values in test group as compared to control group and showed statistical significant difference (P < 0.001) just before surgery.Combination of multimedia based video information at the time of PAC and short verbal briefing on the day of surgery by the attending anesthesiologist provides effective management of perioperative anxiety. It can be cost effective way of enhancing patient care and providing adequate information to people with reading and comprehension difficulties.
