Unexpected pulmonary aspiration during endoscopy under intravenous anesthesia

Area of Science:

• Anesthesiology
• Gastroenterology
• Pulmonology

Background:

• Intravenous anesthesia is frequently used for endoscopy, enhancing patient comfort and pain management.
• Cardiopulmonary effects are typically the primary focus when assessing anesthesia risks.
• Pulmonary aspiration risk is often underestimated in routine endoscopic procedures.

Observation:

• A patient developed unexpected aspiration pneumonia following a gastroscopy procedure performed under intravenous anesthesia.
• No specific risk factors for aspiration were initially identified in this patient.
• The event occurred despite the common use and perceived safety of intravenous anesthesia for gastroscopy.

Findings:

• Pulmonary aspiration can occur even in the absence of typical predisposing factors.
• Aspiration pneumonia is a potential complication of intravenous anesthesia during gastroscopy.
• This case underscores the importance of considering aspiration as a risk in all patients undergoing such procedures.

Implications:

• Anesthesiologists and endoscopists should maintain a high index of suspicion for pulmonary aspiration.
• Pulmonary aspiration should be considered a potential risk factor associated with anesthesia for gastroscopy.
• Further research may be warranted to identify subtle risk factors and optimize preventative strategies.
