Introduction: In the surgical environment, the number of patients with arterial hypertension has increased signi?cantly. Adequate advice to patients regarding the management of their preoperative antihypertensive medication is intended to reduce complications throughout the perioperative period, both due to its suspension and maintenance. However, despite the indications for antihypertensive management in many hospitals, the incidence of refractory hypotension during surgery is a frequent complication. Objective: To describe the incidence of refractory hypotension in hypertensive patients treated with ARA II undergoing general anesthesia in elective surgery at a public hospital in the State of Durango, Mexico. Material and Methods: Observational, descriptive, longitudinal, retrospective study. The sample size was calculated with a 95% con?dence level and an expected frequency of 30%. The ?les in compliance with the selection criteria were randomized through the SPSS statistical program to be incorporated for analysis. Discussion and Conclusions: Seventy-six records of individuals undergoing surgery under general anesthesia with ARAII-based treatment for hypertension were analyzed. The incidence of refractory hypotension was 3%. The incidence of trans-surgical hypotension was 69%. The most frequently identi?ed risk factor was failure to discontinue antihypertensive treatment before surgery. Antihypertensive medication should be continued until the day of surgery, apart from renin-angiotensin blocking agents, which should not be administered on the day of surgery and can be resumed after surgery.
