Intraoperative Platelet and Plasma Improves Survival in Patients Operated for a rAAA: A Follow-up Evaluation

Abstract 

Objectives

Continued haemorrhage remains a significant contributor to mortality in massively transfused patients. We found that early administration of platelets and plasma reduced mortality from 54% to 36% in rAAA patients. The aim of the present evaluation was to evaluate whether reduced mortality in rAAA patients related to a pro-active transfusion therapy is maintained.

Design

Single-centre observational study.

Methods

Mortality of patients operated for rAAA 2006–07 was compared to that of patients operated 2004–05 (intervention group; n=50) and 2002–04 (control group, n=82).

Results

64 consecutive patients with rAAA received, similar to the intervention group, more platelets (5 and 4 vs. 0 units, P<0.05) and plasma (12 and 11 vs. 7 units, P<0.05) intraoperatively and had a higher platelet count (158 and 155 vs. 69×10⁹/L, P<0.0001) upon arrival at the intensive care unit and the 30-day mortality remained reduced (24% and 36% vs. 56%, P<0.01 and P=0.02, respectively) as compared to the control patients.

Conclusions

Early administration of platelets and plasma, together with red blood cells maintained reduced mortality in patients operated for rAAAin a 18 month period.
