purpose: to evaluate the efficacy of sub-tenon block (preemptive analgesia) following general anesthesia and before the beginning of scleral buckling and cryopexy in retinal detachment (rd) surgery on decreasing intra- and post-operative complications. methods: sixty eight patients scheduled for rd surgical repair with asa (american society of anesthesiologists) class і or ii were enrolled in t...

Objectives: Vitreous and retinal (VR) surgery with or without scleral buckling is associated with significant postoperative pain in adults, and recent studies have addressed the effect of retro or peribulbar block on these parameters. VR surgery in children has received little attention regarding the incidence of pain and the role of regional anesthesia in modifying these parameters. In this st...

The oculocardiac reflex (OCR) is a well–described cardiac depressor reflex that may result in significant cardiac rate or rhythm changes, sinus and junctional bradycardia, heart block or asystole. It is also known by the eponym Aschner-Dagnini Reflex, being independently reported in 1908 by both Guiseppe Dagnini and later Bernard Aschner.1,2 The OCR is classically depicted as being precipitated...

The authors compare the effect of two muscle relaxants, atracurium and pancuronium, on the bradycardia resulting from the oculocardiac reflex during eye surgery for strabismus in children. Two groups, each composed of 15 children, received either pancuronium or atracurium during strabismus operations. Heart rate and rhythm were observed at several points during the operations, and the changes t...

Aim. Efficacy of granisetron and combination of granisetron and dexamethasone was evaluated for prevention of postoperative nausea and vomiting (PONV) in children undergoing elective strabismus surgery. Methods. A total of 136 children (1-15 years) were included. Children received either granisetron (40 mcg/kg) [group G] or combination of granisetron (40 mcg/kg) and dexamethasone (150 mcg/kg) [...

Background In this prospective, non-randomized study, we tested the hypothesis if oculocardiac reflex (OCR) can be used as a predictor of postoperative nausea and vomiting following strabismus surgery in children. Methods 88 children aged between 2 and 16 years undergoing strabismus surgery were enrolled in the study between 2009 and 2011. All anaesthetic drugs were given in a specific sequence...
