| Popis: | Introduction: The treatment of nasal sinus diseases with Functional Endoscopic Sinus Surgery (FESS) is a well-established and popular method. This procedure is performed under general anaesthesia or local anaesthesia. Intentional induction of hypotension has helped limit intraoperative blood loss. A bloodless surgical field improves visibility and lowers the possibility of damaging nearby structures, achieved by reducing the baseline Mean Arterial Pressure (MAP) by 30% or maintaining MAP at 60-70 mmHg. Aim: To compare the efficacy of dexmedetomidine and Magnesium Sulphate (MgSO4) in producing hypotensive anaesthesia during FESS. Materials and Methods: This randomised clinical study was conducted at BLDE Shri BM Patil Medical College and Research Centre, Vijayapura, Karnataka, India, from January 2021 to July 2022. In this study, 70 patients, aged 18 to 60 years of either sex, admitted for FESS surgeries under general anaesthesia with American Society of Anaesthesiologists (ASA) Grade 1 and 2 were randomly divided into two groups: 35 patients in the dexmedetomidine group and 35 patients in the MgSO4 group. Dexmedetomidine was given to group D as a loading dose of 1 μg/kg, followed by an infusion of 0.5 μg/kg/h, and MgSO4 was given to group M as a loading dosage of 40 mg/kg, followed by an infusion of 15 mg/kg/h. MAP was kept above 65 mmHg during induced hypotension. Parameters studied included Heart Rate (HR), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), MAP. Data was analysed using International Business Machines (IBM) Statistical Package for Social Sciences (SPSS) Statistics Software Version 23.0. A p-value |
