Abstract

Objective: To evaluate the value of amniotic fluid lactate concentration in the prediction of spontaneous labour among preterm premature rupture of membranes (PPROM) cases and to get information about these cases in means of maternal and fetal perspective standardisation. Material and Method: This study was designed as a prospective observational study. PPROM cases between 24-34 gestational weeks underwent sterile speculum examination whereby amniotic fluid was obtained and tested for lactate level and best cut-off amniotic fluid lactate values to predict onset of spontaneous labour within 48 hours and 7 days were determined. Results: Mean age of the cases was 26.40±6.14 years. Mean gestational age during examination was 31.18±2.57 weeks and mean time until birth was 9.89±1.45 (mean±standart error mean) (95% CI: 6.91-12.86) days. The best cut-off value to predict the onset of spontaneous labour within 48 hours and 7 days was 7 mmol/l and 8.1 mmol/l (sensitivity 92.3%; specificity 36.6%; positive LR 1.46; negative LR 0.21 vs sensitivity 68.1%; specifivity 57.7%; positive LR 1.61; negative LR 0.55, respectively), but areas under curve were not statistically significant (AUC=0.56%, 95% CI 0.44-0.67; p=0.380, AUC=0.59, 95% CI 0.47-0.70; p=0.196 respectively). Conclusion: The best predictive amniotic fluid cut-off values were determined for spontaneous onset of labour within 48 hours or 7 days among PPROM cases, but there was not a statistically significance between groups in terms of lactate levels. Extended, randomized, controlled studies are necessary to determine the predictive value of amniotic fluid lactate concentration on onset of spontaneous labour.

Özet

Amaç: Preterm erken membran rüptürü (PEMR) olgularında amnion sıvısı laktat konsantrasyonunun, kendiliğinden doğum eylemi üzerine öngörüsü araştırılarak; böylesi olgularda maternal ve fetal yaklaşım standardı açısından bilgi sağlanması amaçlandı. Gereç ve Yöntem: Bu çalışma prospektif gözlemsel bir çalışma olarak dizayn edilmiştir. Yirmi dört-otuz dört gebelik haftaları arası aktif su gelişi olan PEMR olguları steril spekulum muayenesi sırasında elde edilen amnion sıvı laktat düzeyi açısından test edildi ve lojistik regresyon analizi kullanılarak amnion mayii laktat düzeyi ile olguların 48 saat ve 7 gün içinde kendiliğinden doğum eylemine girme açısından en iyi kesme değerleri belirlendi. Bulgular: Olguların ortalama yaşı 26,40±6,14 yaş idi. Muayene sırasındaki ortalama gebelik yaşı 31,18±2,57 hafta, doğuma kadar geçen ortalama süreyse (ortalama±standart error mean) 9,89±1,45 (%95 GA: 6,91-12,86) gün idi. Doğum eyleminin 48 saat ve 7 gün içinde başlamasını öngörmede en iyi kesme değeri 7 mmol/l ve 8,1 mmol/l idi (duyarlılık %92,3; özgüllük %36,6; pozitif LR 1,46; negatif LR 0,21, duyarlılık %68,1; özgüllük %57,7; pozitif LR 1,61; negatif LR 0,55, sırasıyla), fakat eğrilerin altında kalan alanlar anlamlı değildi (AUC=0,56, %95 GA 0,44-0,67; p=0,380, AUC=0,59, %95 GA 0,47-0,70; p=0,196 sırasıyla). Sonuç: Bu çalışmada PEMR olgularında hastaların 48 saat ve 7 gün içinde kendiliğinden doğum eylemine girmesi için en iyi kesme değerleri saptanmış, fakat bu değerler için gruplar arasında laktat açısından istatistiki anlamlı fark saptanmamıştır. Aktif su gelişi saptanan PEMR olgularında amnion sıvısı laktat düzeyinin kendiliğinden doğum eylemine girme üzerine öngörüsünü saptamada büyük çaplı, randomize, kontrollü çalışmalara gereksinim vardır.
