Epinephrine to Prevent Postintubation Collapse in Shocked ICU Patients

Endotracheal intubation is a lifesaving procedure that is performed in various settings within the hospital or even in the pre-hospital field. However, it can result in serious hemodynamic complications, such as post-intubation hypotension (PIH) and cardiac arrest. Push-dose pressor (PDP) is common practice for rapid hemodynamic correction in post-intubation hypotension. In this study the investigators will use intravenous Epinephrine bolus for prevention of post intubation collapse in septic patients predicted by shock index in intensive care unit.
