Summary
Brief summary (as posted)
The aim of this study is to compare between peribulbar block and subtenon block as an adjunct to general anesthesia in children undergoing strabismus surgery on oculocardiac reflex (OCR), post-operative analgesia and postoperative vomiting. Both techniques will be compared to intra-operative intravenous (IV) paracetamol combined with general anesthesia as a sole anesthetic technique.

- Peribulbar group (Group P)
- description
- The peribulbar group (P group \_ 40) received a peribulbar block with 0.25 mL/kg of a 1:1 local anesthetic mixture (LAM) of 0.5% bupivacaine and 2% lignocaine. Peribulbar block using a two-injection technique was performed by a second anesthetist under sterile conditions and before the application of surgical drapes. LAM was injected both infratemporal and superonasally using a 26-G needle, in contrast to the single infratemporal injection approach.

- sub-tenon group (group S)
- description
- Children in the sub-Tenon group (sub-Tenon group (S), n \_ 40) received a sub-Tenon block. Sub-Tenon's anesthesia was performed with 0.5% bupivacaine (0.08 ml/kg), bearing in mind not to exceed the maximum dose. Under sterile conditions, a 19- gauge curved blunt metallic cannula (25 mm) was inserted into sub-Tenon's space and the local anesthetic was injected by the ophthalmologist after the application of surgical drapes.
