The PROTECT trial: Effect of titrated versus conventional induction of general anaesthesia using a target-controlled infusion system on haemodynamics in patients undergoing non-cardiac surgery - protocol for a multicentre, expertise-based randomised controlled trial.

ABSTRACT:

Introduction

Hypotension is a frequent complication after induction of general anaesthesia leading to end-organ injury, for which elderly and multimorbid patients are particularly susceptible. The extent of hypotension depends, among other factors, on the dose and rate of propofol administration. Target-controlled infusion systems are widely used to administer short-acting anaesthetics such as propofol and remifentanil. Commonly, induction is started with a fixed effect-site concentration. Titration, an alternative method of induction using an incremental augmentation of propofol, leads to a reduced induction dose and rate of propofol. We hypothesise that the titration method improves haemodynamic stability compared with conventional induction.
