Peribulbar Block Versus Subtenon's Injection in Redo Vitreoretinal Surgery
- Conditions
- Analgesia
- Registration Number
- NCT04978415
- Lead Sponsor
- Abeer Samir Salem
- Brief Summary
To compare the efficacy and efficiency of peribulbar block versus sub-Tenon's capsule injection of local anesthetic in redo vitreoretinal surgery
- Detailed Description
Sixty patients undergoing vitreoretinal surgery were randomized to receive either peribulbar or sub-Tenon's capsule injection of 8 ml of a 20:80 mixture of 2% lidocaine and 0.5% bupivacaine with 60 IU hyalouronic acid.
The primary outcome measured was intraoperative eye pain, which was rated by patients in both groups using an 11-point (0-10) numerical visual analogue scale immediately after.
The surgeons indicated whether they perceived patient discomfort during 4 different stages of the operation: opening of the conjunctiva, vitrectomy (if performed), placement of scleral buckle (if performed) or using the laser probe, and closing of the conjunctiva.
The need for supplemental local anesthesia, and use of IV sedation for additional pain control intraoperatively were compared between the two groups.
