Abstract

Objective To investigate the impact of intrapartum fever on maternity and fetus. Design Retrospective cohort study. Setting Women’s Hospital of Nanjing Medical University, Nanjing, Jiangsu Province, China Population We studied intrapartum fever, as well as non-fever parturients, between January 1, 2018 and December 31, 2018. Methods We collected pregnancy outcomes of intrapartum fever and non-fever mother and neonatal data. Main outcomes and measures The obstetrics outcomes, complete blood cell count (CBC) and thereby converted neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and monocyte to lymphocyte ratio (MLR), as well as vaginal secretion were observed in women with and without intrapartum fever. Results Prepartum white blood cell (WBC), red blood cell (RBC), and hemoglobin (Hb) were all higher in febrile group, and WBC still higher but RBC and Hb lower after birth. Postpartum NLR and MLR were all higher in fever group but not preferred overtly difference before delivery. Additionally, the comparison of WBC, RBC, Hb, platelets (PLT), neutrophils, and monocytes in prepartum and postpartum all showed significant difference. Conclusions The differences of the prepartum WBC, RBC, Hb, and monocytes existed in the intrapartum fever and afebrile groups. Besides, the parturition could bring about the change of the value of CBC and intrapartum fever might aggravate or alleviate this change. Additionally, the intrapartum fever might not be caused mainly by infection and the difference between bacteria and fungus could reflect in the CBC.
