Cardiovascular Response during Induction, Laryngoscopy, Intubation and Surgery in Normotensive and Controlled Hypertensive Patients Undergoing Abdominal Surgeries under General Anaesthesia

ABSTRACT

Introduction: Hypertension is very common conditionamong adult and elderly patients. Ii is one of the importantrisk factor of atherosclerosis of vessels. Anesthetist’s morecommonly tackle the management of treated and untreatedhypertensive patients. The considerable concern of anaesthtistnot only strong association with coronary artery disease butpotential target organ damage. This study was conducted toassess cardiovascular response in different stages of generalanesthesia in abdominal surgeries.Material and methods: Sixty adult patients undergoingdifferent elective abdominal operations under generalanesthesia were included. Patients were divided into A andB group. A group consists of normotensive patients while Bgroup consists of controlled hypertensive patients. Their bloodpressure were controlled on single antihypertensive drug.B group further divided into B1 and B2. B1 group patientswere on beta blockers (BB) while B2 group patients were onangiotensin converting enzyme inhibitors(ACEI).Results: There was decrease in SAP, DP and HR in all groupsafter induction while there was increase in SAP, DP and HRin all groups after laryngoscopy and intubation. There wasminimal rise in SAP, DP and HR in all groups during surgery.The rise of HR was comparatively less in BB group thanACEI group during laryngoscopy and intubation while rise inSAP was comparatively more in ACEI than BB group duringsurgery.Conclusion: On the basis of the present observation it canbe concluded that pressure response and cardiac response(cardiovascular response) to laryngoscopy and intubationappears to be unaffected with these antihypertensive drugs.
