Abstract Details

Purpose:

Hypertension is the commonest intra-operative medical complication in patients undergoing cataract surgery under topical anaesthesia. We performed a study to identify risk factors for high blood pressure requiring anaesthetic interventions.

Setting:

The study was performed within the ambulatory surgical unit of a teaching hospital.

Methods:

We prospectively studied 257 elective cataract operations in 238 patients at one centre preceded by a history taking and physical examination. Per-operative adverse medical events and type of management were recorded.

Results:

The overall rate of hypertension during surgery was 10.4% (n=27). Independent risk factors for developing a per-operative hypertension were female sex (OR=3.8 [1.4-10.3]; p=0.008), age >80 years (OR=4.5 [1.5-13.8]; p=0.008) and anxiety (OR=10.5 [4.1-27.0]; p<0.001). Incidence of hypertension was not significantly reduced by premedication (OR=0.5 [0.1-2.2]; p=0.4). There was no significant difference between patients with or without hypertension history in terms of hypertensive events occurence (OR=3.1 [0.6-15.4]; p=0.15). Interventions to manage hypertension, anxiety or pain were similar regardless past medical history or physical examination.

Conclusions:

Specific at-risk population should be targeted pre-operatively to reduce intra-operative hypertension.
