Incidence of preoperative high blood pressure in cataract surgery among hypertensive and normotensive patients.
Incidence of preoperative rise in blood pressure (BP) in cataract surgery among hypertensive and normotensive patients.


OBJECTIVE
To study the incidence of preoperative rise in BP in cataract surgery among normotensive individuals and hypertensive patients with historic good BP control in a population without other major chronic diseases.


METHODS
Ophthalmology Service of a University Hospital.


METHODS
A prospective study with 822 patients older than 40 years of age, with cataract surgery indication, and without major chronic diseases other than hypertension. The patients were divided in two groups: hypertensive and normotensive. Preoperative data, physical exams and medical adverse events were recorded in an evaluation questionnaire.


RESULTS
The sample included 427 normotensive (52%) and 395 hypertensive patients (48%). The two groups had similar proportions of operations that were cancelled and not subsequently rescheduled, 2% (eight patients) in each group. The incidence of preoperative rise in BP was 3.7% in the normotensive group and 10.9% in the hypertensive group (P < 0.001).


CONCLUSIONS
Hypertensive patients with historic good BP control and without other major co-morbidities present a larger incidence of preoperative rise in BP than normotensive individuals in cataract surgery.
