Abstract
ABSTRACT
Background
Hypertension is an important public health challenge worldwide and is most
important modifiable risk factor for cardiovascular, cerebrovascular and renal
disease. Blood pressure determination forms an integral part of anaesthesiologist’s
evaluation of hispatient’s condition prior to and during surgery. Data are not
available which indicate changes in blood pressure occurring preanaesthetically
in hospitalized patients. There are several risks from untreated preoperative
hypertension in perioperative and postoperative phase.
Objective
To know the incidence of hypertension in preoperative patients undergoing major
surgery
Methods
This retrospective observational study was based on the data collected from
preanaesthetic checkup record book from January 2010 to December 2010.
Results
A total of 955 patients were studied and analyzed in terms of hypertension and
demographic characteristics. The total incidence of hypertension in preoperative
phase was 10.16%. Among them 64.9% being male and 35.1% female. Maximum
incidence was found in age group 50-59 years i.e. 26.6%. Among the case detected
maximum patients i.e. 52% were patients with newly diagnosed hypertension and
among those under medications 61.1% were using calcium channel blockers.
Conclusion
Knowing the incidence will help in proper preoperative optimization of the
hypertensive patients and also help in decreasing the incidence of postoperative
complications..
