Sedoanalgesia with Remifentanil in patients over 60 years of age submitted to peribular block

Abstract

Objective: To determine the efficacy between two doses of sedoanalgesic whith remifentanil in patients over 60 years old submitted to peribulbar block. Method: An, experimental, prospective and non contemporary research work was carried out in a period of months, with a unicentric randomized clinical trial designo f case control distribution; the sample was integrated by 44 patients , over 60 years old, with ophthalmopathies that required the perfomance of peribulbar block, for ambulatory surgical resolution . These patients were divided into two groups and before the peribulbar block intravenous boluses of remifentanil were administered to each group .Group A was treated with a dose of 0,3 mcg/kg/peso weigth and group  B  a dose of 0,6 mcg/kg/peso weigth . In addition an instrument to evaluate the leve lof sedation, pain and hemodynamic variables was applied to compare results. Results: 64% female, the mean age was 67.4 ± 6.8 years, 97.7% was ASA II. There were no statistically significant differences between both doses of remifentanil in sedoanalgesic effectiveness, hemodynamic variables and adverse effects. Conclusión: remifentanil in bolus at the established doses is a useful , safe and effective therapy for the improvement of pain and reach an optimal leve lof sedation in older patients undergoing peribulbar block .
