Abstract:
Respiratory arrest is an uncommon complication of retrobulbar anesthesia. We present a case in which it occurred following a 0.75% bupivacaine and 2% lidocaine retrobulbar block and analyze the possible causes. We conclude that the most important of these were the relatively high concentration and volume of the anesthetic and a faulty technique.
Insights
Respiratory arrest is a rare complication of retrobulbar anesthesia. High anesthetic concentration, volume, and faulty technique were identified as key contributing factors in this case.
Area of Science:
- Anesthesiology
- Ophthalmology
Background:
- Retrobulbar anesthesia is a common procedure in ophthalmic surgery.
- Complications, though rare, can be serious, including respiratory arrest.
Observation:
- A patient experienced respiratory arrest after receiving a retrobulbar block.
- The block utilized 0.75% bupivacaine and 2% lidocaine.
Findings:
- The anesthetic concentration and volume were considered relatively high.
- A faulty injection technique was also identified as a potential cause.
Implications:
- This case highlights the importance of careful anesthetic selection and administration in retrobulbar blocks.
- Reviewing technique and anesthetic parameters is crucial for preventing severe complications.
