Summary
A single medial peribulbar injection effectively numbs the eye for intra-ocular surgery, matching the efficacy of the standard two-injection technique. This simplifies the procedure without compromising patient comfort or surgical outcomes.
Area of Science:
- Ophthalmology
- Anesthesiology
- Surgical Procedures
Background:
- Peribulbar anesthesia is commonly used for intra-ocular surgery.
- The standard technique involves two peribulbar injections.
- Exploring single-injection methods may enhance efficiency.
Purpose of the Study:
- To compare the efficacy of a single medial peribulbar injection versus the standard two-injection technique.
- To assess pain and globe akinesia following peribulbar anesthesia for intra-ocular surgery.
Main Methods:
- Prospective randomized study involving 107 patients undergoing elective intra-ocular surgery.
- Patients were randomly assigned to receive either a single medial or a standard two-injection peribulbar technique.
- Anesthesia was administered using prilocaine 3% with felypressin.
- Assessment of globe akinesia and intraoperative pain.
Main Results:
- No significant difference in globe akinesia between the single and two-injection groups.
- No significant difference in intraoperative pain levels between the two techniques.
- Prilocaine 3% with felypressin demonstrated effectiveness in both methods.
Conclusions:
- A single medial peribulbar injection is as effective as the standard two-injection technique for intra-ocular surgery.
- The single injection method offers a potentially simpler and equally effective alternative for peribulbar anesthesia.
- Further research may explore patient and surgeon preference for simplified anesthesia protocols.
