目的探讨高血压病人腹部外科手术前有否控制血压的必要性。方法回顾分析531例行腹部外科手术的高血压病人围手术期病情变化。结果一、二级高血压术前控制血压与否对围手术期病情无显著影响(P>0.05)，三级及收缩期高血压术前未控制组围手术期并发症显著高于术前控制组(P<0.05)。结论一、二级高血压术前抗高血压治疗与否不增加手术危险性；三级及收缩期高血压术前应控制血压低于180/110mmHg(24.0/14.7kPa)，且宜平稳1～2周，待病情稳定后施行择期手术。

Clinical analysis of 531 cases of abdominal surgery with hypertension.

Objective To evaluate adbomen surgery in patients who are found to have poorly controlled or untreated hypertension before operation.Methods From January 1997 to December 1998,the perioperative clinical data of 531 patients with hypertension and undergoing abdomen surgery in our hospital were retrospectively analyzed.Results The incidences of perioperative hypertensive events were not significantly different,between controlled and uncontrolled patients with grade one and grade two (P>0 05).In grade three and systolic hypertension,certain perioperative complications in patients with poorly controlled hypertension were higher than in those with well-controlled hypertension(P<0 05).Conclusion The patients with grade on e and grade two hypertension are not at increased operative risk.In Patients with grade three and systolic hypertension,perioperative complications are increased and elective surgery should be postponed until their blood pressure is brought under 180/110 mmHg over 1 to 2 weeks.
