Preoperative ultrasound guided inferior venacava collapsibility index as a guide to predict hypotension following spinal anaesthesia in patients scheduled for elective surgery

Background: Spinal anaesthesia is the most commonly employed anaesthetic technique for infraumbilical surgeries. Post spinal hypotension a encountered complication which can lead to organ under perfusion and ischemia. Severe episodes of intraoperative have been proposed as an independent risk factorin development postoperative adverse outcomes prolonged hospital stay. However, there are no reliable methods determine patients at induced hypotension. This study investigated whether preoperative ultrasound guided inferior venacava collapsibility index (IVC-CI) could predict following anaesthesia. Objectives were measure compare incidence among with IVC-CI>50% IVC-CI<50%. Materials Methods: prospective observational was conducted in department anaesthesia, Yenepoya Medical College Hospital, Mangalore during period between October 2016 2018. After ethical committee approval informed consent, 73 belonging “American society Anesthesiology” (ASA) grade I & II, aged 18 65 years, scheduled elective surgeries require selected. Preoperative ultrasonography done IVC-CI these patients. All ultrasonographic examinations performed by same anaesthesiologist.
