Abstract

Abstract
Background: The use of the Perfusion Index (PI) and Internal Jugular Vein Collapsibility Index (IJV-CI) for predicting hypotension during anaesthesia is a promising domain pivotal in clinical monitoring. Both indices are non-invasive tools that can provide valuable insights into a patient's circulatory status and the likelihood of hypotension, which is an essential concern during anaesthesia. The aim of this study was to predict the occurrence of post-induction hypotension in patients undergoing Endoscopic retrograde cholangiopancreatography (ERCP) using PI and/or IJV-CI to evaluate the sensitivity and specificity of each parameter (PI and IJV-CI) in predicting post-induction hypotension.

Patients and methods: This study was conducted on 60 patients scheduled for ERCP with sedation. Patients was randomly divided into two groups, group (I) PI was used to predict hypotension and group II the IJV-CI was used beside the PI. Propofol and fentanyl were applied to induce sedation and continuous infusion was conditioned to keep sedation score 3.
In group (I) baseline values were recorded for PI, then every 2 minutes for a period of 16 minutes after induction of sedation. In group II besides PI measurement, IJV-CI was evaluated before induction of anaesthesia and after 16 minutes using Sonosite ultrasound machine.
All patients was subjected to monitoring anaesthesia care during the procedure. Incidence of hypotension after induction and the total doses of propofol (mg) used in the first 16 minutes of the procedure were recorded.
