Incidence of preoperative rise in blood pressure (BP) in cataract surgery among hypertensive and normotensive patients.
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.
Ophthalmology Service of a University Hospital.
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.
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).
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.
目的：研究在无其他重大慢性疾病的人群中，血压（BP）正常的个体和血压控制良好的高血压患者在白内障手术前血压升高的发生率。
对象与方法：这是一项前瞻性研究，共纳入了 822 名年龄大于 40 岁、有白内障手术适应证且无高血压以外其他重大慢性疾病的患者。患者被分为两组：高血压组和血压正常组。在评估问卷中记录了术前数据、体格检查和医疗不良事件。
结果：该样本包括 427 名血压正常（52%）和 395 名高血压患者（48%）。两组中取消手术且未重新安排的比例相似，每组均有 2%（8 例）。血压正常组术前血压升高的发生率为 3.7%，高血压组为 10.9%（P<0.001）。
结论：在白内障手术中，血压控制良好且无其他重大合并症的高血压患者术前血压升高的发生率高于血压正常的个体。
