A Comparative Evaluation of Dexmedetomidine and Midazolam in Monitored Anaesthesia Care for Tympanoplasty
Journal Title: Indian Journal of Anesthesia and Analgesia - Year 2018, Vol 5, Issue 3
Abstract
Introduction: Monitored Anaesthesia care (MAC) has been defined by the American Society of Anaesthesiologists as a diagnostic or therapeutic procedure done under local anaesthesia along with sedation and analgesia. Advantages of performing tympanoplasty under MAC with local anaesthesia are less bleeding, improved post-operative analgesia, early and smooth recovery and discharge from hospital with least expenditure. The biggest advantage is intra-operative communication and assessment of hearing in the patient. Aim: The study was done to evaluate the efficacy of dexmedetomidine and midazolam for intra-operative sedation and analgesia in monitored anaesthesia care and to compare and assess any adverse effects in different groups of study. Methodology:The study was Conducted in the Department of Anaesthesiology, Gandhi Medical College and Hamidia Hospital, Bhopal on ASA Grade I and II patients scheduled for tympanoplasty. 90 patients of either sex of ASA Grade I and II, aged between 16 and 40 years were studied.All patient were premedicated with injection glycopyrolate 0.01mg/kg IV and Inj pentazocine 0.3 mg/kg over 1 min. Group A received Dexmedetomidine: Bolus dose 1mcg/kg IV followed by 0.4mcg/kg per hour, and Group B received Midazolam: Bolus dose of 0.04 mg given over 1 min. Oxygen supplementation through nasal catheter was given. Sedation was titrated to Ramsay Sedation score of ³3. Rescue sedation with Midazolam 0.01mg/kg was given if RSS was <3 . Surgery was allowed to commence when Visual Analogue Scale (VAS) was <3. Sedation was assessed using Ramsay sedation Scale. Result and Conclusion: Sedation with Dexmedetomidine was found to be better alternative to midazolam in monitored anaesthesia care performed in minor ENT surgical procedures. It provides a calm sedated patient. Also, fall in the HR and MAP was seen in more number of patients of Group A than in Group B. This caused decreased bleeding, thus providing bloodless surgical field comfortable for the surgeon.
