L&D – Amnioinfusion Guideline and Procedure for Amnioinfusion
L&D – Amnioinfusion Guideline and Procedure for Amnioinfusion. Purpose: Replacing the amniotic fluid with normal saline has been found to be a safe, simple, and very effective way to reduce the occurrence of repetitive variable decelerations. Procedure: Initiation of Amnioinfusion will be ordered and performed by a Certified Nurse Midwife (CNM) or physician (MD). 1. Prepare NS or LR 1000ml with IV tubing in the same fashion as for intravenous infusion. Flush the tubing to clear air. 2. An intrauterine pressure catheter (IUPC) will be placed by the MD/CNM. 3. Elevate the IV bag 3-4 feet above the IUPC tip for rapid infusion. Infuse 250-500ml of solution over a 20-30 minute time frame followed by a 60-180ml/hour maintenance infusion. The total volume infused should not exceed 1000ml unless one has access to ultrasound and can titrate to an amniotic fluid index (AFI) of 8-12 cm to prevent polyhydramnios and hypertonus. 4. If variable decelerations recur or other new non-reassuring FHR patterns develop, notify the MD/CNM. The procedure may be repeated as ordered. 5. Resting tone of the uterus will be increased during infusion but should not increase > 15mmHg from previous baseline. If this occurs, infusion should stop until there is a return to the previous baseline then it can be restarted. An elevated baseline prior to infusion is a contraindication. 6. Monitor for an outflow of infusion. If there is a sudden cessation of outflow fetal head engagement may have occurred increasing the risk of polyhydramnios. Complications are rare but can include iatrogenic polyhydramnios, uterine hypertonus, chorioamnionitis, uterine rupture, placental abruption, and maternal pulmonary embolus. -
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 -

Assessment of amniotic fluid volume (AFV) is an integral part of antenatal ultrasound evaluation during screening exams, targeted anatomy examinations, and in tests assessing fetal well-being. 1 di 17 18/06/2014 11:10 Amniotic fluid volume: When and how to take action http://contemporaryobgyn.modernmedicine.com/pr... Abnormal AFV has been associated with an increased risk of perinatal mortality and several adverse perinatal outcomes, including premature rupture of membranes (PROM), fetal abnormalities, abnormal birth weight, and increased risk of obstetric interventions.1 A recent systematic review demonstrated associations between oligohydramnios, birthweight <10th percentile, and perinatal mortality, as well as between polyhydramnios, birthweight >90th percentile, and perinatal mortality. The predictive ability of AFV alone, however, was generally poor.2 How to assess AFV Ultrasound (U/S) examination is the only practical method of assessing AFV. -

Disrupted amniotic fluid volume is associated with an increased risk for the fetus. The present research aims to investigate the effect of cutoff point amniotic fluid index on pregnancy prognosis at the third trimester of pregnancy in Shariati hospital of Bandar Abbas. Materials and methods: In the present analytical, cross-sectional research, AFI ≤ 5 cm was considered as oligohydramnios; AFI 5.1-8 was taken as the cut-off point; AFI ˃ 8.1-24 was regarded as normal; AFI ˃ 24 was considered as polyhydramnios. The data were analyzed via SPSS version 16.0 using Chi-squared test, Fisher’s test, Mann-Whitney U-test and Spearman’s correlation coefficient. P-value was set at ≤ .05 for the significance of data. Findings: Subjects with cut-off point AFI (5.1-8) were 38 (40.4%); those with normal AFI (8.1-24) were 56 (59.6%). The mean score of AFI was 8.85±9.54cm. -

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. -

14th World Congress in Fetal Medicine Amnioinfusion in the etiological diagnosis and therapeutics of oligohydramnios: 17 years of experience Borges-Costa S, Bernardo A, Santos A Prenatal Diagnosis Center, Hospital Garcia de Orta, Almada, Portugal Objective To review the maternal and fetal outcomes of all amnioinfusions performed for the diagnosis and treatment of oligohydramnios during pregnancy (excluding labor). Methods This is a retrospective study of 31 singleton pregnancies with oligohydramnios in the second and third trimesters which underwent transabdominal amnioinfusion between December/1997 and December/2014 in the Prenatal Diagnosis Center at the Hospital Garcia de Orta. The gestational age ranged from 15 weeks and 5 days to 32 weeks and 2 days (average 22 weeks). The initial amniotic fluid index ranged from 0 to 6, 5 cm. The procedure was done only by trained professionals. Under ultrasound guidance, isotonic fluid, such as normal saline or Ringer's lactate, is infused into the amniotic cavity via a 20 G needle inserted through the uterine wall. The volume infused ranged from 100 to 800cc (average 380cc). A genetic study was conducted in 29 cases (93, 5%), performed after amniocentesis (26 cases) or cordocentesis (3 cases). In all cases, there was an exhaustive study of the fetal anatomy after the amnioinfusion. In this study the following parameters were evaluated: maternal characteristics (age, personal and obstetrical history), evolution of pregnancy, perinatal mortality and maternal complications.
