Subconjunctival bupivacaine in strabismus surgery

Abstract

A prospective study was performed to assess the effect of subconjunctival bupivacaine on pain relief following strabismus surgery. A total of 36 children were randomly allocated to receive either subconjunctival infiltration of bupivacaine or normal saline at the conclusion of surgery. Post-operative pain was evaluated using a 4-point assessment score. Subconjunctival bupivacaine provided significantly better post-operative pain relief (P < 0.001). We suggest that it could be used routinely in strabismus surgery, as it improves post-operative comfort thereby facilitating day case surgery.

Subtenons lidocaine injection for postoperative pain relief after strabismus surgery in children: A prospective randomized controlled trial

“…10 Topical amethocaine 1% drops and subconjunctival infiltration with bupivacaine 0.5% administered at the conclusion of strabismus surgery have been shown to be equally effective in reducing postoperative pain, [11][12][13] although another study did not show any additional analgesic effect of either of these interventions when compared to placebo. 14 Our pilot study found that a subtenons injection of lidocaine was associated with a reduction in postoperative systemic analgesia requirement (29% vs. 64% of controls, P ϭ 0.052), and with a trend to reduced pain scores that reached statistical significance at the 2-h observation.…”

Pain relief for strabismus surgery in children: a randomised controlled study of the use of preoperative sub-Tenon levobupivacaine

“…Lignocaine is a shorter-acting anaesthetic with a duration of 1–2 h when given as a sub-Tenon block, while the effect of bupivacaine and levobupivacine lasts for 3–3.5 h 22. Similarly, the administration of postoperative subconjunctival bupivacaine has reduced pain scores after strabismus surgery in children 16. Another study compared subconjunctival bupivacaine to topical tetracaine in children having squint surgery, with both giving effective analgesia 17.…”

Safety and efficacy of peribulbar block as adjunct to general anaesthesia for paediatric ophthalmic surgery

“…el‐Kasaby et al . (22) evaluated the effects of subconjunctival bupivacaine instillation along with preemptive oral acetaminophen and topical amethocaine in children undergoing ophthalmic surgery. Watson (23) and Habib (24) have evaluated topical amethocaine after strabismus surgery.…”
