    American Journal of Obstetrics and Gynecology, 2007
    Co-Authors: Julie M Johnson, Suneet P Chauhan, Christopher S Ennen, Amy Niederhauser, Everett F Magann
    Abstract:

    Objective The objective of the study was to ascertain the diagnostic accuracy of 3 criteria of oligohydramnios in identifying 4 peripartum complications. Study Design The 3 definitions of oligohydramnios were Amniotic Fluid Index (AFI) 5.0 cm or less and AFI Results The 95% confidence intervals for the prevalence of oligohydramnios using the 3 criteria are significantly different in the antepartum or intrapartum analysis. The LR was Conclusion The 3 criteria for determining the adequacy of Amniotic Fluid are not fungible, and they are not useful diagnostic tests for identifying peripartum complications because LR is

  • intrauterine growth restriction and oligohydramnios among high risk patients
    American Journal of Perinatology, 2007
    Co-Authors: Suneet P Chauhan, Michelle Taylor, Dawn Shields, Donna Parker, James A Scardo, Everett F Magann
    Abstract:

    The purposes of this study were (1) to determine the prevalence of oligohydramnios (Amniotic Fluid Index 5.0 cm for adverse peripartum outcomes. This was a retrospective review of high-risk pregnancy that had reliable gestational age (GA) and needed weekly biophysical profile (BPP). Along with 95% confidence intervals (CIs), we calculated the likelihood ratios (LRs) and used guidelines promulgated by Evidence-Based Medicine Working Group. Among the 1859 singletons undergoing BPP, IUGR (estimated fetal weight 5.0 cm, and oligohydramnios with IUGR is a poor predictor of peripartum complications.

  • Amniotic Fluid Index vs single deepest pocket technique during modified biophysical profile a randomized clinical trial
    American Journal of Obstetrics and Gynecology, 2004
    Co-Authors: Suneet P Chauhan, Everett F Magann, Dorota D Doherty, Francis Cahanding, Frank Moreno, Jack H Klausen
    Abstract:

    Objective The purpose of this study was to determine the superior technique, if either, of the Amniotic Fluid Index (AFI) vs the single deepest pocket technique in predicting an adverse pregnancy outcome among high-risk patients undergoing antenatal testing. Study design Patients having modified biophysical profile (nonstress test plus sonographic estimation of Amniotic Fluid) were randomized to either have AFI or determination of the presence or absence of a 2 × 1-cm single deepest pocket. Results Between January of 1997 and December of 2001, 1080 women were randomized with 530 women in the AFI arm, and 558 in the 2 × 1 pocket arm. The maternal demographics and prenatal complications were similar between groups. Significantly more patients were identified as having oligohydramnios using AFI (17%) compared with using 2 × 1 pocket (10%) ( P =.002). The overall rate of cesarean section for nonreassuring fetal heart rate (FHR) tracing was 3.8% (30 cases, with 16 cases in the AFI-monitored, and 14 cases in the 2 × 1 pocket–monitored groups, respectively, P =.608). Logistic regression analysis showed no difference between the groups with respect to the ability to identify patients who underwent cesarean section for nonreassuring FHR tracing during labor ( P =.999). The umbilical artery pH P =.688) and admission to the newborn intensive care unit were also comparable between groups. Conclusion During antepartum fetal surveillance, use of single deepest pocket compared with Amniotic Fluid Index is associated with a significantly lower rate of suspected oligohydramnios.

  • biophysical profile with Amniotic Fluid volume assessments
    Obstetrics & Gynecology, 2004
    Co-Authors: Everett F Magann, Dorota A Doherty, Suneet P Chauhan, Karen Field, Patrick Muffley, John C Morrison
    Abstract:

    To compare the Amniotic Fluid Index (AFI) with the single deepest pocket technique along with the other components of the biophysical profile (BPP) in predicting an adverse pregnancy outcome. Prospective, randomized trial of Amniotic Fluid assessment by AFI or single deepest pocket during a BPP. Cesarean delivery for fetal distress was the primary outcome evaluated. The AFI was used in 273 pregnancies and the single deepest pocket in 264. The AFI significantly increased the number of pregnancies labeled as oligohydramnios, 102 women (38%) compared with 46 women (17%; P 5), 20 of 170 (12%), underwent a cesarean delivery for fetal distress than the women with normal Fluid by the single deepest pocket technique (2 cm × 1 cm pocket present) group, 12 of 218 (6%; P = .037, OR = 2.22, 95% confidence interval 1.05–4.70). The AFI offers no advantage in detecting adverse outcomes compared with the single deepest pocket when performed with the BPP. The AFI may cause more interventions by labeling twice as many at-risk pregnancies as having oligohydramnios than with the single deepest pocket technique. I

    Abstract:

    Abstract Objective: Our purpose was to assess whether antepartum oligohydramnios is associated with adverse perinatal outcomes. Study Design: Women delivered between July 1, 1991, and September 30, 1996, who underwent ultrasonography at ≥34 weeks' gestation were analyzed. Oligohydramnios was defined as an Amniotic Fluid Index ≤50 mm. Perinatal outcomes in pregnancies with oligohydramnios were compared with those with an Amniotic Fluid Index of >50 mm. Results: In our analysis of 6423 pregnancies, 147 (2.3%) were complicated by oligohydramnios.

  • how well do the Amniotic Fluid Index and single deepest pocket indices below the 3rd and 5th and above the 95th and 97th percentiles predict oligohydramnios and hydramnios
    American Journal of Obstetrics and Gynecology, 2004
    Co-Authors: Everett F Magann, Dorota A Doherty, Suneet P Chauhan, Friedrich W J Busch, Federico Mecacci, John C Morrison
    Abstract:

    Abstract Objective This study was undertaken to determine whether the Amniotic Fluid Index (AFI) and single deepest pocket percentiles can reliably identify a dye-determined Amniotic Fluid volume. Study design Ultrasound measurements and dye-determined volumes were prospectively collected. Oligohydramnios predictors included AFI and single deepest pocket below the 3rd and 5th percentiles, and hydramnios predictors were based on AFI and single deepest pocket above the 95th and 97th percentiles. Results Two hundred ninety-one women with singleton pregnancies participated, including 75 pregnancies (26%) with oligohydramnios and 31 pregnancies (10%) with hydramnios. The predictive ability of the AFI and single deepest pocket indices ( 95th and 97th percentiles) ranged between 33% and 46%. The best prediction was for normal Fluid volume with an accuracy of 83% to 94%. Conclusion Amniotic Fluid indices perform best for the identifying normal AF volumes, whereas the identification of oligohydramnios or hydramnios is poor.

  • intrapartum oligohydramnios does not predict adverse peripartum outcome among high risk parturients
    American Journal of Obstetrics and Gynecology, 1997
    Co-Authors: Suneet P Chauhan, Everett F Magann, John C Morrison, Nancy W Hendrix, Lawrence D Devoe
    Abstract:

    Abstract OBJECTIVE: Oligohydramnios can be defined by an Amniotic Fluid Index STUDY DESIGN: An Amniotic Fluid Index was obtained in 490 consecutive parturients with medical or obstetric complications and a reliable gestational age. After each delivery, an umbilical arterial blood gas analysis was obtained. Both measures of Amniotic Fluid Index were rated as screening tests with use of sensitivity, specificity, predictive values, and receiver-operator characteristic curves. RESULTS: The incidences of cesarean section for fetal distress and umbilical arterial pH p = 0.0004, relative risk 5.0, 95% confidence interval 2.9 to 8.4). Sensitivity and positive predictive values of an Amniotic Fluid Index CONCLUSION: Both criteria for oligohydramnios are poor predictors of adverse outcome for high-risk intrapartum patients.
