Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups

subtenon's block
we use the subtenon cannula to inject the local anesthetic mixture
peribulbar block versus subtenon's block
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 0.75% bupivacaine with 60 IU hyalouronic acid.
two groups 30 patient each (group p and group s) after connecting the patient to the monitor, we give him sedation 50 mg propofol, apply a nasal cannula group P: receives 2 injection peribulbar block group S: receives single injection subtenon Patients rate their pain sensation in both groups using an 11-point (0-10) numerical visual analogue scale immediately after surgery.
peribulbar block
