The Cesarean Section Patient by Leukocyte Reduction Filters (2)
The cesarean section patient by leukocyte reduction filters, the blood samples collected included (1) unwashed blood from the surgical field (prewash), (2) washed blood (postwash), (3) washed and filtered blood (postfiltration) leukocyte reduction filters, and (4) maternal central venous blood drawn from a femoral catheter at the time of placental separation.
Significant reductions in the following parameters were seen when the postfiltration samples were compared to the prewash samples (median [25th–75th percentile]): squamous cell concentration (0.0 [0.0–0.1 counts/high-powered field (HPF)] vs. 8.3 counts/HPF [4.0–10.5 counts/HPF], , P < 0.05); bacterial contamination (0.1 [0.0–0.2]vs. 3.0 [0.6–7.7] colony-forming units (CFU)/ml, P < 0.01); and lamellar body concentration (0.0 [0.0–1.0]vs. 22.0 [18.5–29.5] thousands/μl, P < 0.01).
