Usefulness of pre-emptive peribulbar block in pediatric vitreoretinal surgery: A prospective study

Abstract

Peribulbar block appears to be a safe and clinically superior alternative to intravenous opioid for pediatric VR surgery.

The effect on outcome of peribulbar anaesthesia in conjunction with general anesthesia for vitreoretinal surgery

“…These findings can be attributed to blocking the afferent limb of the oculocardiac reflex [10] and reducing the afferent stimuli from muscle traction, thus preventing central hyperexcitability by noxious stimuli [11]. Similar results have been described in previous studies [1,2,6,12,13]. However, most of these studies included patients scheduled for surgery without scleral buckling [1,2,6].…”

“…Surgical dissatisfaction because of insufficient akinesia resulting from partial blockade [5] and patient discomfort during prolonged surgery involving scleral buckling are further limitations to the use of local anaesthesia alone. The combination of general anaesthesia and peribulbar anaesthesia may reduce these drawbacks [6]. The aim of this study was to evaluate the effect of peribulbar anaesthesia when used in conjunction with general anaesthesia on peri-operative outcome after vitreoretinal surgery.…”

Retrobulbar Block in Pediatric Vitreoretinal Surgery Eliminates the Need for Intraoperative Fentanyl and Postoperative Analgesia

“…Pain score was significantly lower in group RB than in group F right after LMA removal (1 [0, 3.5] vs 5 [3,7], P = 0.003). No difference was detected between pain scores assessed at 2 h (2 [1, 2.5] vs 2 [1,3]) and 24 h (0 [0, 0.5] vs 0 [0, 1]) postoperatively.…”

“…All children in group F consumed intraoperative fentanyl rescue (average intraoperative fentanyl consumption, 1.3 ± 0.3 μg/kg) compared with none in group RB. Pain scores assessed with Faces, Legs, Activity, Cry and Consolability were significantly lower in group RB than in group F (1 [0, 3.5] vs 5 [3,7], P = 0.003) immediately after laryngeal mask airway removal. Heart rate in group RB was significantly lower than that in group F before anesthesia induction, at the beginning and end of surgery, respectively.…”

Experiences with the local retrobulbar anesthesia in ophthalmologic surgery of the standing horse

“…Bei einer Allgemeinnarkose kann somit die additive Lokalanästhesie vor der Operation dazu beitragen, postoperative Schmerzen zu vermeiden (Kissin 2000, Katz 2001, Kissin 2002. In der Augenchirurgie wird dabei häufig ein genauer Injektionszeitpunkt empfohlen (Chung et al 1988, Duker et al 1991, Gottfresdottir et al 1993, Maberley et al 1995, Williams et al 1995, Ates et al 1998, Deb et al 2001, Kristin et al 2001, Mahfouz und Nabawi 2002, Henzler et al 2002, Kawohl et al 2002, Subramaniam et al 2003, Müller et al 2003, Vogt et al 2003. Alle humanmedizinischen Studien geben bei einer präoperativen Injektion geringere postoperative Schmerzen bzw.…”
