RESUMO
STUDY OBJECTIVE: To determine the incidence and contributing factors of complications for patients receiving regional ophthalmic anesthesia. DESIGN: Retrospective analysis. SETTING: Tertiary-care eye center. MEASUREMENTS: Anesthesia records of ophthalmic blocks performed from January 2003 to June 2009 were reviewed. The frequency of block-related complications and details of each complication were recorded. MAIN RESULTS: A total of 33,363 peribulbar blocks were performed, with a total incidence of 0.12% (41 cases). These complications may be divided into systemic complications, 18 cases (0.053%) and needle-related complications, 23 cases (0.068%). CONCLUSION: Peribulbar block complications were rare. In this series, experience of caregivers and axial and needle length were not contributing factors.

BACKGROUND: Profound bradycardia during eye surgery is potentially serious event. In clinical practice this Oculocardiac Reflex (OCR) is most often encountered during squint surgery. The objective of this study was to assess the occurrence of OCR and prove the effect of anticholinergic premedication (atropine) to prevent OCR. METHODS: This study comprises of sixty patients (age 2-30 years) operated for squint surgery under general anaesthesia. Cases were divided into two groups of thirty each. Group 1 was premedicated with intravenous injection of atropine and Group 2 did not receive any premedication. Patients were monitored during operation for any bradycardia or dysrhythmias. RESULTS: The observed data showed occurrence of 70% OCR in Group 2 as compared to only 10% in Group 1. Severe bradycardia in 40% cases of Group 2 needed intervention by IV injection of atropine. CONCLUSION: Our study showed that atropine premedication in the patients of squint surgery under general anaesthesia definitely obtunds OCR and prevents any untoward effects of dysrhythmias during eye surgery.
