Research Article: Reverse shock index (RSI) as a predictor of post-intubation cardiac arrest (PICA)

Date Published: 2023-12-07

Abstract:
Endotracheal intubation (ETI) in critically ill patients is a high-risk procedure due to the increased risk of cardiac arrest, and several factors may predict poor outcomes in these patients. The aim of this study was to investigate the role of some factors, especially newly introduced vital signs such as the reverse shock index (RSI), in predicting post-intubation cardiac arrest (PICA) in critically ill adult patients.

Introduction:
Many critically ill patients referred to the emergency department (ED) develop complications during endotracheal intubation (ETI). In addition to the complications caused by unsuccessful intubation, one of the recognized consequences of ETI is cardiac arrest [1]. Cardiac arrest following emergent ETI in critically ill patients can be a life-threatening complication rendering a poor prognosis for these patients. This complication usually occurs within the first minutes after intubation [2]. Therefore, ETI is a…
