Objective:
To determine the relation of malnutrition and underlying diagnosis to the length of stay in the Intensive Care Unit (ICU) and to mortality after lung transplantation (LTX).
Design:
Retrospective ICU chart review.
Setting:
Cardiothoracic ICU in a University hospital.
Patients:
Fifty-one consecutive patients who suffered from end-stage lung disease from April 1992 to January 1994.
Interventions:
None.
Measurements And Results:
The median time spent in the ICU was 5 days (range, 2-123 days). Patients with an underlying diagnosis of obstructive lung disease had significantly shorter ICU stays (median 4 days; range, 2-28 days) than those with restrictive lung disease (median 7 days; range, 2-123 days) (p = 0.005) or pulmonary hypertension (median 10 days' range, 2-38 days) (p = 0.041). Significant differences in ICU duration were observed between patients after double lung transplantation (median 10 days; range, 2-123 days) and those after single lung transplantation (median 4 days; range, 2-36 days) (p = 0.004). No statistically significant difference in ICU duration was found between patients with different nutritional statuses. In those patients who could not be discharged from the ICU before the 5th day, a body mass index (BMI) below the 25th percentile was a statistically significant risk factor for ICU mortality (p = 0.05).
Conclusions:
We conclude that the type of transplant procedure and the underlying diagnosis are important predictive indicators of ICU duration. A poor nutritional status (BMI below the 25th percentile) is a risk factor for ICU mortality in cases of patients who stay for 5 days or longer in the ICU.
