Summary
The single-injection peribulbar block is a safe and effective anesthesia method for anterior segment eye surgery. This technique demonstrated a low rate of sight-threatening complications in a large prospective study.
Area of Science:
- Ophthalmology
- Anesthesia
Background:
- Peribulbar block is a common anesthesia technique for anterior segment eye surgery.
- Ensuring effective anesthesia and akinesia is crucial for successful ophthalmic procedures.
Purpose of the Study:
- To evaluate the safety and efficacy of a single-injection peribulbar technique.
- To determine the incidence of complications and need for supplemental anesthesia.
Main Methods:
- Prospective study of 2,684 consecutive cases.
- Single-injection peribulbar block performed over three years.
- Data collection on complications and supplemental anesthesia requirements.
Main Results:
- A low incidence of 0.6% for sight-threatening complications.
- No cases were canceled due to peribulbar hemorrhage.
- Only 1.2% of patients required supplemental anesthesia.
Conclusions:
- The single-injection peribulbar technique is a highly effective and safe method for anesthesia and akinesia in anterior segment eye surgery.
- This technique minimizes the risk of serious complications and the need for additional anesthesia.
