BACKGROUND Cardiovascular effects for drugs such as hyoscine butylbromide are poorly documented in the literature, unlike atropine, which is considered the antimuscarinic of choice in the presence of intraoperative bradycardia. AIM The aim of the study was to describe the dose-related cardiovascular effect of hyoscine butylbromide in patients between 18 and 65 years of age, with low perioperative risk undergoing elective surgery under general anaesthesia on an outpatient basis or hospitalised at our institution between 1 January and 31 May 2019. METHODS Descriptive, cross-sectional, retrospective study; 28 patients with low perioperative risk who underwent general anaesthesia were selected. Changes in heart rate and blood pressure were analysed during the first 6 minutes after the administration of hyoscine butylbromide. The data obtained was recorded in a Microsoft Excel database and analysed using the Excel analysis tool and IBM SPSS. RESULTS The average dose of 0.15mg/kg of hyoscine butylbromide achieved an increase in heart rate and mean arterial pressure in 96% and 92.8%, respectively, in the first 6 minutes after the administration. Significant changes in heart rate and blood pressure were obtained during the first 6 minutes at doses between 0.05mg/kg and 0.15mg/kg. CONCLUSION Hyoscine butylbromide generates positive effects on the heart rate and blood pressure of patients under general anaesthesia, representing a possible alternative in the management of intraoperative bradycardia.
