Efficacy of albumin supplementation in the surgical intensive care unit: a prospective, randomized study.

OBJECTIVE

To determine the efficacy of supplemental 25% albumin in reducing morbidity and mortality rates in the surgical intensive care unit (ICU).

DESIGN

Prospective, randomized, unblinded clinical study.

SETTING

Surgical ICU in a community hospital.

PATIENTS

Two hundred nineteen patients with admission circulating albumin concentrations of < 3.0 g/dL (< 30 g/L). The groups were well matched regarding age, sex, Acute Physiology and Chronic Health Evaluation II scores and initial circulating albumin concentrations.

INTERVENTIONS

The treatment group (n = 116) received 37.5 g/day of albumin until the circulating albumin concentration increased to > 3.0 g/dL (> 30 g/L). The control group (n = 103) received no supplemental albumin. Both groups received standard nutritional support.

MEASUREMENTS AND MAIN RESULTS

The complication rate was 44% in the albumin group vs. 36.9% in the controls (p = .29). The albumin patients had a mortality rate of 10.3% vs. 5.8% in the control group (p = .22). There were no significant differences between the groups in the number of days spent receiving mechanical ventilation or in the tolerance to tube feedings.

CONCLUSIONS

Routine supplemental administration of 25% albumin is expensive and offers no apparent outcome advantage and should be abandoned in the treatment of patients in the surgical ICU.
