Apnoea after retrobulbar block.

Area of Science:

• Ophthalmology
• Anesthesiology

Background:

• Retrobulbar block is a common anesthesia technique for cataract surgery.
• Potential complications, though rare, require careful consideration.

Observation:

• Two patients experienced apnea (cessation of breathing) after receiving a retrobulbar block.
• This complication occurred during or shortly after the anesthetic procedure.

Findings:

• The cases highlight the importance of vigilant monitoring post-retrobulbar block.
• Potential causes include anesthetic toxicity, vagal stimulation, or respiratory depression.

Implications:

• Prompt recognition and management of apnea are crucial for patient safety.
• Anesthesiologists and ophthalmologists should be prepared to manage this adverse event.
