Abstract

Objective: This study was conducted to elucidate the predictive value of hematological indices, the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and mean platelet volume (MPV), to determine the clinical outcome of placental abruption in women regarding stillbirth.

Methods: This retrospective review of medical charts was performed in a tertiary center experienced for maternal, fetal, and neonatal care, including 89 pregnant women with placental abruption with or without stillbirth. The results of the hemogram tests with hematological indices, including the NLR, PLR, and MPV, which are the routinely obtained parameters both at admission and 4 h postoperatively, were correlated with other clinical parameters.

Results: The findings showed that although there were remarkable changes in some of the clinical features of women with placental abruption with or without stillbirth, in general, the study groups were found comparable regarding these variables. The values of NLR, PLR, and MPV in women with stillbirth presented remarkable changes when hemogram tests were used as pre-operative and post-operative laboratory examinations, although these changes did not correlate with each other meaningfully.

Conclusion: Stillbirth is one of the most important complications of placental abruption requiring rapid diagnosis and regular follow-up after its surgical management. To fine-tune emergent management of placental abruption in women with stillbirth, the indices of NLR, PLR, and MPV calculated at the first admission as well as during follow-up of the patients have clinical value as easily obtainable laboratory findings like other hematological parameters.
