title: Analyzing the effects of intra-operation video-clip display on hemodynamic and satisfaction of patients during lumbar discectomy under spinal anesthesia.
abstract: OBJECTIVE
  Most neurosurgeons and anesthesiologists prefer the less invasive intervention for most surgeries; recently, the lumbar anesthesia is more popular method. In this study we have tried to distract the attention of the patients to their favorite video-clip instead of their surrounding operating room background to evaluate the hemodynamic as well as their satisfaction during the operation.
  
  
  METHODS
  80 patients who were scheduled for an elective one level discectomy under the regional spinal anesthesia enrolled in this prospective randomized clinical trial. The patients were randomized with sealed envelope method and each envelope was randomly assigned from this set of envelops to be either in case group one (video group) or control groups two (no audio and video and only head phone on their ears) group. In all patients, systolic and diastolic blood pressure, pulse rate and SPO2 were measured and recorded in the questionnaire charts.
  
  
  RESULTS
  Of the 80 patients with Lumbar disk herniation, 53 patients were male and 27 female. The mean age for all patients was 44 year. Systolic and diastolic blood pressure at the end of surgery was significantly lower in video group (P=0.045 and 0.004). Systolic Blood pressure differences between 3(rd) and 5(th) and the end of the surgery with minute zero was significantly less in the video group. (P=0.025, 0.018 and 0.030). Diastolic blood pressure differences between 3(rd) and 5(th) and the end of the surgery with minute zero was significantly less in the video group.(P=0.051, 0.019 and 0.15). Pulse rate differences between first, 3(rd), 5(th) and exactly before leaving the recovery room with minute zero was significantly less in the video group. (P=0.015, 0.028, 0.030 and 0.008).
  
  
  CONCLUSIONS
  According to our study, by displaying patient's favorite video clip during the surgical intervention we could highly reduce the patient's attention to what is happening in operating room and therefore, decrease their anxiety and stress.
