Intraoperative bronchospasm under spinal analgesia--a case report.

Area of Science:

• Anesthesiology
• Respiratory Medicine
• Neurosurgery

Background:

• Spinal anesthesia, a common anesthetic technique, primarily involves blocking sympathetic nerves.
• High spinal blocks are known to cause respiratory compromise due to phrenic nerve involvement.
• Mid-spinal analgesia typically spares the respiratory system.

Observation:

• A healthy patient undergoing inguinal hernia repair experienced bronchospasm under subarachnoid block.
• The highest sensory level of the spinal block reached T6.
• Patient anxiety exacerbated the respiratory symptoms.

Findings:

• This case presents an unusual instance of bronchospasm associated with mid-spinal anesthesia.
• This is potentially the first reported case of bronchospasm directly linked to spinal anesthesia.
• The unblocked parasympathetic nervous system is hypothesized to play a role in this respiratory complication.

Implications:

• Highlights the potential for unexpected respiratory complications even with mid-spinal anesthesia.
• Suggests a need to consider parasympathetic nervous system activity in managing respiratory side effects of spinal anesthesia.
• Emphasizes careful patient monitoring for respiratory distress during and after spinal procedures.
