[Respiratory arrest following retrobulbar block]

Area of Science:

• Ophthalmology
• Anesthesiology
• Neurology

Background:

• Retrobulbar block is a common anesthesia technique for ophthalmic procedures.
• Complications, though rare, can be serious and require prompt management.
• Understanding potential adverse events is crucial for patient safety.

Observation:

• A patient experienced transient apnoea and cranial nerve paralysis shortly after retrobulbar block.
• Symptoms resolved spontaneously within a few hours.
• Literature review indicates apnoea is a rare, typically early-onset complication.

Findings:

• Apnoea following retrobulbar block is an infrequent but recognized risk.
• The complication is usually observed within ten minutes of anesthetic administration.
• Skilled medical staff and resuscitation facilities are vital for managing this event.
• Peribulbar anesthesia has not been associated with this specific complication.

Implications:

• Highlights the importance of vigilance and preparedness for rare complications during retrobulbar blocks.
• Emphasizes the need for readily available resuscitation equipment and trained personnel.
• Suggests peribulbar anesthesia as a potentially safer alternative for avoiding post-block apnoea.
