Medial Canthus Single-Injection Peribulbar Anesthesia: A Prospective Randomized Comparison With Classic Double-Injection Peribulbar Anesthesia

To compare peribulbar and subtenon anaesthesia in patients undergoing cataract surgery. In a hospital based randomised comparative interventional study, patients who underwent cataract surgery were randomised into two groups, one receiving peribulbar and the other subtenon anaesthesia. Pain during administration, pain during surgery, chemosis, subconjunctival haemorrhage globe akinesia were noted and compared in the two groups. Any other complications which occur also noted. The pain during administration was significantly lesser in subtenon injection as compared to peribulbar anaesthesia. Pain during surgery was comparable in the two groups. Incidence of subconjunctival haemorrhage and chemosis was more in subtenon injection as compared to peribulbar anaesthesia. Globe akinesia was achieved more effectively in subtenon injection as compared to peribulbar injection. The subtenon anaesthesia is comparable to peribulbar anaesthesia with few additional advantages and is recommended as safe and effective alternative to peribulbar anaesthesia for cataract surgery.

“…Lidocaine and mepivacaine are both amide local anesthetics with short onset, intermediate duration, and similar potency. [2][3][4][5] Regardless of the block used, mepivacaine is classically reported to have similar onset time but slightly longer effect than that of lidocaine. [2][3][4][5][6][7][8]12 In a work on epidural anesthesia, mepivacaine had a similar duration to a lidocaine-epinephrine mixture, which is expected to provide longer block duration than does plain lidocaine.…”

“…Mepivacaine is now widely used for eye blocks. 2,3 Lidocaine is classically assumed to provide slightly shorter duration than does mepivacaine, in a multitude of blocks (epidural, peripheral, and even eyelid blocks). [4][5][6][7][8] This point has not been explored by use of episcleral (sub-Tenon's) block for eye surgery.…”

“…An 11-point (0-10) numerical pain reporting scale (NRS) 18 was used to assess patient-reported pain during injection of anesthesia, intraoperatively and postoperatively by the independent assessor. NRS is a linear scale subdivided into 10 equal intervals, with the left end marked 0, indicating no pain, and the right end marked 10, representing the worst pain imaginable.…”

Purpose:To compare the akinetic and the analgesic effects of peribulbar and posterior sub-Tenon's anesthesia in patients undergoing cataract surgery.Methods:In a hospital-based randomized comparative interventional study, patients aged 50 years and above who underwent elective surgery for uncomplicated cataract were randomized to receive either peribulbar block or posterior sub-Tenon block. Pain during injection, surgery, and after surgery was assessed using numerical reporting scale (NRS). Limbal excursion was measured with a transparent meter rule.Result:A total of 152 eyes of 152 patients were studied. Peribulbar and sub-Tenon regional blocks provided comparable adequate akinesia (P = 0.06) and similar levels of analgesia (P = 0.10) during cataract surgery. Both techniques also provided similar levels of analgesia to the patient during injection and in the immediate postoperative period. Ninety-two percent of patients who had peribulbar and 97% of those who had sub-Tenon blocks reported either mild pain or no pain at all during surgery (P = 0.49). There was no report of severe pain in all patients during the stages of the surgery. Occurrence of chemosis and subconjunctival hemorrhage was more common in sub-Tenon than peribulbar anesthesia.Conclusions:This study shows that peribulbar and posterior sub-Tenon routes of administering anesthetic substances is comparable in providing adequate akinesia and analgesia for cataract surgery with minimal complications. Therefore, both techniques are effective and safe for cataract surgery among Nigerians.
