Postintubation Hypotension in General Anesthesia: A Retrospective Analysis.

Area of Science:

• Anesthesiology
• Critical Care Medicine
• Vascular Surgery

Background:

• Postintubation hypotension (PIH) is a significant adverse event following endotracheal intubation.
• PIH is associated with poorer patient outcomes in emergency settings.

Purpose of the Study:

• To determine the incidence of PIH in patients undergoing tracheal intubation for vascular surgery.
• To assess the impact of PIH on critical patient outcomes.

Main Methods:

• A structured chart audit was conducted on adult patients.
• The study included patients intubated for vascular surgery at a tertiary care center over three years.
• Outcomes analyzed were in-hospital mortality, ICU length of stay, and need for postoperative hemodialysis or mechanical ventilation.

Main Results:

• The incidence of PIH was 60% (837/1395 patients).
• Patients with PIH exhibited higher mortality (8.8% vs. 5.2%), extended ICU LOS (7.9% vs. 2.0%), and increased need for postop mechanical ventilation (20.7% vs. 3.8%).
• Multivariate analysis confirmed PIH was independently associated with extended ICU LOS (OR 2.55), postop ventilation (OR 2.43), and a composite endpoint (OR 1.72).

Conclusions:

• PIH affects 60% of patients intubated for vascular surgery.
• PIH is significantly associated with adverse outcomes, including prolonged ICU stays and increased requirement for mechanical ventilation.
