A Randomized Controlled Trial to Assess the Efficacy of a Pre-operative Virtual Operation Theatre Tour on Anxiety and Patient Satisfaction in Adults Undergoing Elective Surgery.

Background: The study objective involves the evaluation of preoperative audiovisual information on the operation theater environment as a tool to relieve anxiety in patients posted for infra umbilical elective surgery under spinal anesthesia. Perioperative anxiety is detrimental to both intraoperative hemodynamic instability and postoperative recovery.

Material And Methods: The design was a single-center, prospective, randomized control trial.

Efficacy of Variable Doses of Prophylactic Intravenous Ondansetron in Attenuating Spinal Induced Hypotension in Parturients Undergoing Caesarean Delivery: A Randomised Control Trial.

Introduction Spinal anaesthesia is frequently associated with adverse effects like maternal hypotension and bradycardia. This effect is due to a decrease in systemic vascular resistance, a decrease in central venous pressure or Bezold-Jarisch Reflex (mediated by 5-HT3 receptors). We aimed to measure the effect of three different doses of prophylactic intravenous ondansetron (5-HT3 antagonists) with a placebo on maternal haemodynamics.

Role of Endotracheal Tube Cuff Deflation in Facilitating Passage of Nasogastric Tube.

Background Nasogastric tube insertion is a routinely performed technique in anesthetized and intubated patients. However, failure leads to repeated insertion attempts causing injury, which makes the situation cumbersome. Therefore, we introduce a simple technique of deflating endotracheal tube cuff for nasogastric tube insertion in such patients.
