Abstract
Background: It is debated whether chronic hypertension increases the risk of cardiovascular incidents during anaesthesia.
Methods: We studied all elective surgical operations performed in adults under general or regional anaesthesia between 2000 and 2004, in 24 hospitals collecting computerised clinical data on all anaesthetia since 1996. The focus was on cardiovascular incidents, though other anaesthesia-related incidents were also evaluated.
Results: Among 124 939 interventions, 27 881 (22%) were performed in hypertensive patients. At least one cardiovascular incident occurred in 7549 interventions (6% [95% CI 5.9-6.2%]). The average adjusted odds ratio of cardiovascular risk in patients with chronic hypertension was 1.38 (95% CI 1.27-1.49). However, across hospitals, adjusted odd ratios varied from 0.41 up to 2.25. Hypertension did not increase the risk of other incidents. Conclusions: Hypertensive patients are still at risk of intra-operative cardiovascular incidents. The heterogeneity of the risk to develop cardiovascular incidents varied across hospitals, despite taking into account casemix and hospital characteristics. These variations suggest that anaesthetic practices differ across anesthesia services
