Deteriorating Hypotension and Trepopnea During Left Lateral Decubitus Position Before Spinal Anesthesia

Area of Science:

• Anesthesiology
• Cardiology

Background:

• Chronic heart failure (CHF) is a complex condition affecting cardiac function.
• Spinal anesthesia is a common anesthetic technique for orthopedic surgery.

Observation:

• Two cases of CHF patients experiencing adverse events during pre-anesthetic positioning were observed.
• The left lateral decubitus position precipitated significant hypotension and respiratory distress.

Findings:

• Positioning in left lateral decubitus can induce severe hemodynamic and respiratory compromise in CHF patients.
• These adverse events occurred prior to the administration of spinal anesthesia.

Implications:

• Clinicians should carefully consider patient positioning for orthopedic surgery in those with CHF.
• Pre-anesthetic assessment and monitoring are critical for managing CHF patients undergoing spinal anesthesia.
