title: Transpulmonary polymorphonuclear leukocyte number after cardiopulmonary bypass.
abstract: Polymorphonuclear leukocyte (PMN) numbers were determined in samples of central venous or pulmonary artery blood and in simultaneously drawn samples of systemic arterial blood 5 min before institution of cardiopulmonary bypass (CPB) and 5 min after the termination of CPB in 10 adult patients. In only 2 of 10 patients was the systemic arterial PMN number lower than that in central venous or pulmonary arterial blood in the post-CPB period. The results suggest that intrapulmonary PMN sequestration, reported to be a frequent consequence of complement activation during CPB, is a transient and self-limited phenomenon in most persons.
