Abstract:

Purpose: Pre-eterm is to investigate the role of the neutrophil-lenphocytes ratio (NLR), lymphocytes-monosites ratio (LMR), trombocytes-lymphocytes ratio (PLR), average trombocytes volume (MPV) and C-reactive protein (CRP) values in the determination of the time passed until birth. Tools and Methods: The data used in the study was collected from the hospital records between January 2017 and December 2018 with the approval of our corporate examination facility. Patients who received PEMR diagnosis under the 34 weeks of pregnancy who were not active were included in the study. The CRP, NLR, LMR, PLR and MPV values of all patients are obtained from the laboratory tests received at first application, without given a dose of betametazone for antibiotic prevention and lung maturity to patients. Patients were divided into two groups according to the time from membrane ruptura to birth; patients in group 1 were identified as those who began spontaneous birth in the first 72 hours, and patients in group 2 were identified as those who began spontaneous birth after 72 hours. The two groups are compared in terms of CRP, NLR, LMR, PLR and MPV values. Results: 172 patients provided criteria were included in the study. In Group 1, CRP (median values respectively 1,08 and 0,75 (p = 0,012)) and NLR (median values respectively 6,68 and 4,74 (p = 0,001) were determined higher compared to Group 2, while LMR (median values respectively 3,00 and 4,07 (p = 0,001) were determined lower. The shortness of the period until birth in patients with PEMR is associated with high NLR and low LMR values with CRP. These patients can be advised and can help determine the conditions relating to the patient’s tracking.
