BACKGROUND: After cardiac surgery, most patients
have development of third-space fluid retention, commonly treated
with diuretics. In some patients diuretics are ineffective. In this
subset, a simplified system for ultrafiltration was used for fluid
extraction.
METHODS: After obtaining permission from the institutional
review board, the hospital charts of the first 30 patients having
ultrafiltration were retrospectively reviewed to abstract data on
fluid extraction and patient outcomes. Data are expressed as mean
± standard deviation.
RESULTS: From April 2004 through January 2006,
30 patients were selected for ultrafiltration. In one patient, adequate
intravenous access could not be obtained. There were 11 female and
18 male (age, 69 ± 12 years) postoperative cardiac surgery
patients. The mean ultrafiltration run was 10.5 ± 9 hours,
resulting in fluid extraction of 3528 ± 2111 mL per run and
5596 ± 3870 mL per patient (11 patients had more than 1 run).
Hospital stay was 9.4 ± 4.4 days. Three patients died unrelated
to ultrafiltration.
CONCLUSION: Ultrafiltration as an alternative
means of fluid extraction in postoperative cardiac surgery patients
was effective and well tolerated.
