Vasovagal asystole during spinal anaesthesia

Area of Science:

• Anesthesiology
• Cardiology
• Neurology

Background:

• Spinal anesthesia is a common regional anesthetic technique.
• Vasovagal syncope is a common cause of transient hypotensive episodes.
• Patient positioning and premedication can influence autonomic responses.

Observation:

• A case of vasovagal asystole occurred during spinal anesthesia in the upright position.
• The patient experienced asystole, a severe form of vasovagal syncope.
• Electrocardiograph (ECG) monitoring was performed during the procedure.

Findings:

• The upright position during spinal anesthesia induction was associated with vasovagal asystole.
• Omission of anxiolytic premedication may have contributed to the vasovagal response.
• Continuous ECG monitoring identified the asystolic event during regional anesthesia.

Implications:

• Highlights the importance of continuous ECG monitoring in patients undergoing regional anesthesia.
• Suggests that patient positioning and premedication strategies should be carefully considered to mitigate vasovagal syncope risk.
• Emphasizes the potential for severe autonomic responses during regional anesthesia procedures.
