Ruptured abdominal aortic aneurysm--outcome in a community teaching hospital intensive care unit.
Ruptured abdominal aortic aneurysm (RAAA) is a surgical emergency associated with a high mortality often requiring postoperative intensive care. Our objectives were to assess the outcome of RAAA management in a nontertiary community hospital intensive care unit (ICU) and to compare this with historical data from tertiary hospitals. We also sought to identify variables related to outcome and evaluate the potential of an organ failure score to identify patients at increased risk of death. The study was a retrospective chart review of patients with RAAA over 11 years (1986-1996 inclusive) at Manly District Hospital, a 210 bed community teaching hospital with eight intensive care beds. Forty patients were identified in the study period as having been admitted to ICU after RAAA surgery. There was an overall hospital mortality rate of 47.5% and intensive care mortality rate of 42.5% for successfully operated RAAA. Five variables were significantly different between survivors and non-survivors. These were age, total amount of blood products required, duration of operation, development of hypotension (systolic blood pressure < 90 mmHg) in ICU postoperatively, and APACHE II score at Day 1 ICU. A trend was also found between mortality rate and the number of failed systems after 48 hours intensive care stay. Mortality for a patient with zero failed systems was 38%, one failed system 42%, two 58% and three 67%. Based on these results, management of RAAA in a non-tertiary setting appears appropriate with postoperative care occurring in an ICU where there is adequate equipment and medical and nursing staff experienced in the care of complex critical illness.
