Peri-Operative Changes In Blood Pressure And Rescheduling Of Patients For Laproscopic Cholecystectomy Under General Anaesthesia: An Observational Study In Normotensive And Controlled Hypertensive Patients

Abstract

Background: Hypertension (HTN) is considered as one of the most important reason of premature deaths globally as per World Health Organization.
Aim: To study the incidence of rise in blood pressure peri-operatively in normotensive and controlled hypertension patients and rescheduling of the surgical procedure in patients undergoing Laparoscopic Cholecystectomy.
Methods: Hundred patients scheduled for elective surgical procedures under general anesthesia belonging to ASA grade I and II were included in the study and were randomly divided into two groups with 50 patients in each group. In Group I (n=50), normotensive patients were included and in Group II (n=50), controlled hypertensive patients were included. Both the groups were compared in relation to the hemodynamic changes in perioperative complications.
Results HR, SBP, DBP were significant in intra-operative period at 30, 45, 60 and post-operatively at 0, 15 minutes in both groups (p <0.05). EtCO2 was significant at 15, 30, 45 minutes. SpO2 was not significant (p>0.05) among the study population.
Conclusion: Normotensive patients undergoing laparoscopic cholecystectomy have more hemodynamic stability (HR, SBP, DBP and SpO2, EtCO2) as compared to the controlled hypertensive patients. A controlled hypertensive patient shows more cardiovascular instability in comparison to normotensive patients. These patients needed more anaesthetic balance and more antihypertensive agents for intra-operative BP regulation.
