Fetal Compromise (Acute): Management If Suspected This Document Should Be Read in Conjunction with the Disclaimer
King Edward Memorial Hospital King Edward Memorial Hospital Obstetrics & Gynaecology Obstetrics & Gynaecology CLINICAL PRACTICE GUIDELINE Fetal compromise (acute): Management if suspected This document should be read in conjunction with the Disclaimer Aim To identify suspected or actual fetal compromise and initiate early intervention to promote placental and umbilical blood flow to decrease risk of hypoxia and acidosis. Key points1 1. Fetal compromise in labour may be due to a variety of pathologies including placental insufficiency, uterine hyperstimulation, maternal hypotension, cord compression and placental abruption. Identification and management of reversible abnormalities may prevent unnecessary intervention. 2. Continuous electronic cardiotocograph (CTG) monitoring should be commenced when fetal compromise is detected at the onset of labour or develops during labour. 3. A normal CTG is associated with a low probability of fetal compromise and has the following features: Baseline rate 110-160 bpm Baseline variability 6-25 bpm Accelerations of 15 bpm for 15 seconds No decelerations. 4. The following features are unlikely to be associated with fetal compromise when occurring in isolation: Baseline rate 100-109 bpm Absence of accelerations Early decelerations Variable decelerations without complicating features. 5. The following features may be associated with significant fetal compromise and require further action (see management section on next page): Baseline fetal tachycardia >160 bpm Reduced or reducing baseline variability -
INTRODUCTION Effect of Different Dosages of Intravaginal Misoprostol
Original Article Gynecology and Obstetrics Medical Journal of Islamic World Academy of Sciences Effect of Different Dosages of Intravaginal Misoprostol for Second Trimester Pregnancy Termination Maysoon Sharief1, Enaas S. Al-Khayat1 1Department of Gynecology and Obstetrics, College of Medicine, University of Basrah, Basrah, Iraq. ABSTRACT Miscarriage is a common complication of early pregnancy; however; curettage and dilation are considered standard methods taking care of early pregnancy failure. Misoprostol has been used as an alternative agent for termination of early pregnancy. Therefore, this study was aimed to compare the efficacy and side effects of two different intravaginal misoprostol trials for the second trimester pregnancy termination of missed miscarriage between 14 and 23 weeks. A clinical trial was carried out in Basrah Maternity & Children Hospital during the period from October 2011 to November 2012. A total of 100 women experienced missed miscarriages at 14-23 weeks of gestation were admitted for medical termination of pregnancy. Patients were divided into the following two groups: Group 1: 50 patients received 400 µg of intravaginal misoprostol/8 hours. Group 2: 50 patients received 800 µg of intravaginal misoprostol/8 hours. The patients were followed up for 24 hours. The primary outcome measure was induction-miscarriage interval; the secondary outcomes were the rate of successful miscarriage and complete miscarriage; the incidence of side effects was compared in both groups. The rates of successful termination of pregnancy in both groups 1 and 2 were 86% and 90%, respectively. The success rates of the drug in group 1 were 0%, 12%, 36%, 34%, 10%, and 4% after first, second, third, fourth, fifth, and sixth doses, respectively; whereas, the success rates in group 2 were 24%, 34%, 24%, 12%, 4%, and 0% after first, second, third, fourth, fifth, and sixth doses, respectively. -
