BACKGROUND
Physiologic increases in the leukocyte count and segmental neutrophil percentage during pregnancy alter the ability of these indices to predict infection.
METHODS
Women with cesarean deliveries were assessed by leukocyte counts and segmented neutrophil percentage as well as clinical signs to detect postoperative infection.
RESULTS
In 157 consecutive patients undergoing cesarean deliveries there was a significant physiologic increase between the preoperative and postoperative leukocyte count (12.4 +/- 3.9/uL vs. 14.8 +/- 3.4/uL, P < 0.001). The leukocyte count after delivery did not discriminate whether or not the patient would develop a postpartum infection or have significant hyperpyrexia.
CONCLUSION
Due to physiologic changes associated with pregnancy, the leukocyte count and segmented neutrophil percentage do not predict infection. Therefore clinical findings are most important in diagnosing postpartum infections.
背景
孕期白细胞计数和分叶中性粒细胞百分比的生理性增加改变了这些指标预测感染的能力。
方法
通过白细胞计数、分叶中性粒细胞百分比以及临床体征对剖宫产妇女进行评估，以检测术后感染情况。
结果
在157例连续接受剖宫产的患者中，术前和术后白细胞计数存在显著的生理性增加（12.4±3.9/μL对14.8±3.4/μL，P<0.001）。分娩后的白细胞计数无法区分患者是否会发生产后感染或出现明显高热。
结论
由于与妊娠相关的生理变化，白细胞计数和分叶中性粒细胞百分比无法预测感染。因此，临床发现对诊断产后感染最为重要。
