Should Prophylactic Endotracheal Intubation Be Performed in Upper Gastrointestinal Bleeding?

Area of Science:

• Gastroenterology
• Pulmonology
• Critical Care Medicine

Background:

• Optimal airway management during endoscopy for acute gastrointestinal bleeding remains debated.
• Previous meta-analyses have explored interventions, but consensus is lacking.
• This study re-evaluates prophylactic endotracheal intubation (PEI) in this patient population.

Purpose of the Study:

• To reassess the effect of PEI on preventing endoscopy complications in acute upper GI bleeding.
• To analyze outcomes including pneumonia, length of hospital stay, aspiration, and mortality.
• To provide updated evidence for clinical decision-making.

Main Methods:

• A systematic review and meta-analysis of studies published up to 2024.
• Inclusion of 11 studies (10 retrospective, 1 prospective) comparing PEI versus no intubation.
• Random effects model used to calculate odds ratios and mean differences for key outcomes.

Main Results:

• PEI was associated with significantly higher odds of pneumonia (OR = 5.83) and longer hospital stays (MD = 0.84 days).
• No statistically significant increase in mortality (OR = 1.68) or aspiration (OR = 2.79) was observed.
• Analysis included 7,332 hospitalized patients with acute upper GI bleeding.

Conclusions:

• PEI before esophagogastroduodenoscopy for acute upper GI bleeding is linked to increased pneumonia and prolonged hospitalization.
• The evidence does not support a significant increase in mortality or aspiration risk with PEI.
• Current findings suggest a need for careful consideration of PEI's risks and benefits.
