PERBEDAAN LUARAN JANIN PADA PERSALINAN PRETERM USIA KEHAMILAN 34-36 MINGGU DENGAN DAN TANPA KETUBAN PECAH DINI

Abstract

Background : Mother who had preterm labour in gestational age of 34-36 weeks with premature rupture of membrane had bigger risk for delivering baby who had asphyxia, low birth weight, and infection than the normal babies. Aim : To determine the association and the effect of premature rupture of membrane to the newborn outcomes in gestational age of 34-36 weeks. Methods : This research was a retrospective obsrevasional study with cross sectional design. The data was taken from RSUP Dr. Kariadi Semarang’s medical record. The data was taken by cluster sampling from January 2011 to December 2011. As the research sample consist of 70 samples, 41 subjects with premature rupture of membrane (58,6%) and 29 subjects without premature rupture of membrane (41,4%). The data was analyzed with Chi Square test and Fisher’s Exact test. Result : Premature rupture of membrane had association with the incident of low birth weight in the gestational age of 34-36 weeks which had p value < 0,0001 CI95% = 7,64-110,69 and PR = 29,07. Such was the case for apgar score in 5th minute (p = 0,002 CI95% = 0,04-0,55 and PR = 0,15 ), 10th minute ( p < 0,0001 CI95% = 0,005-0,119 and PR = 0,02). However premature rupture of membrane hadn’t association with the apgar score in 1st minute ( p = 0,15 CI95% = 0,02-1,48 and PR = 0,16 ). The analysis showed p < 0,05 (significance) for the variable of birth weight and apgar score in the 5th and 10th . Conclusion : Premature rupture of membrane affected the risk of low birth weight in the newborn with the preterm labour. Key words : Preterm, low birth weight, Apgar Score
