Cardiotocography combined with ST analysis versus cardiotocography combined with fetal blood sampling in deliveries with abnormal CTG: a randomized trial.

Purpose: The aim was to investigate if intrapartum monitoring with cardiotocography (CTG) in combination with ST analysis (STAN) results in an improved perinatal outcome.

Methods: We performed a two-center randomized trial. 1013 women with term fetuses in cephalic presentation entered the trial.

Lactate versus pH levels in fetal scalp blood during labor--using the Lactate Scout System.

Objective: To assess if lactate measured with the Scout Lactate System is a reliable alternative to pH in intrapartum monitoring of the fetus.

Methods: A prospective study analyzing (1) the correlation between scalp lactate measured by the Scout Lactate System and the Automatic Blood Laboratory (ABL), (2) the correlation between lactate and pH measured in scalp blood and (3) the correlation between fetal scalp lactate and umbilical cord SBE. The sensitivity/specificity and positive/negative predictive values of lactate in predicting low pH were analyzed and expressed as Receiver Operating Curves (ROC).

Anal incontinence in women with recurrent obstetric anal sphincter rupture: a case control study.

Objectives: To determine the risk of recurrent anal sphincter rupture (ASR), and compare the risk of anal incontinence (AI) after recurrent ASR, with that seen in women with previous ASR who deliver by caesarean section or vaginally without sustaining a recurrent ASR.

Methods: Women with recurrent ASR between January 2000 and June 2011 were identified at two delivery wards in Copenhagen. The women answered a questionnaire with a validated scoring system for AI (St.

The effect of chorionicity and twin-to-twin delivery time interval on short-term outcome of the second twin.

Objectives: To investigate the effect of chorionicity and twin-to-twin delivery time interval on short-term outcome in the second twin as well as to investigate the predictors of adverse outcome in both twins.

Methods: Data included vaginally delivered twins (≥36 weeks) from Copenhagen University Hospitals (2001-2009). The association between delivery interval and adverse outcome parameters was compared for monochorionic (MC) and dichorionic (DC) twins by multiple linear regression.

Cervical dilation at the time of cesarean section for dystocia -- effect on subsequent trial of labor.

Objective: To investigate the effect of cervical dilation at the time of cesarean section due to dystocia and success in a subsequent pregnancy of attempted vaginal delivery.

Design: Retrospective study.

Setting: University hospital in Copenhagen capital area.

Maternal and perinatal complications by day of gestation after spontaneous labor at 40-42 weeks of gestation.

Objective: To evaluate pregnancy outcome after spontaneous labor by day of gestation between 40(+0) and 41(+6) weeks of gestation.

Design: Evaluation of prospectively collected labor ward data.

Setting: University Hospital, Denmark.

Umbilical cord blood lactate: a valuable tool in the assessment of fetal metabolic acidosis.

Objective: The aim of the present study was (1) to evaluate the relationship between umbilical cord arterial blood lactate and pH, standard base excess (SBE), and actual base excess (ABE) at delivery and (2) to suggest a cut-off level of umbilical cord arterial blood lactate in predicting fetal asphyxia using ROC-curves, where an ABE value less than -12 was used as "gold standard" for significant intrapartum asphyxia.

Study Design: This is a descriptive study of umbilical cord arterial blood samples from 2554 singleton deliveries. The deliveries took place at the Department of Obstetrics and Gynaecology, Hvidovre University Hospital, Copenhagen, Denmark where umbilical cord blood sampling and blood gas analysis is part of the routine assessment of all newborns.

Peripartum hysterectomy in Denmark 1995-2004.

Background: Severe postpartum hemorrhage (PPH) is a potentially life-threatening situation that sometimes requires a hysterectomy. We examined the national incidence, risk factors, indications, outcomes and complications of peripartum hysterectomy following vaginal and caesarean delivery.

Methods: Peripartum hysterectomy was defined as a hysterectomy after birth until 1 month after delivery using the codes for hysterectomy from the NOMESCO classification (1995).

Can the reproducibility of fetal heart rate baseline estimation be improved?

Objective: To evaluate the reproducibility of fetal heart rate (FHR) baseline estimation according to an objective and detailed definition presented in this article, by comparison with the FIGO guidelines' definition.

Study Design: Three hundred consecutively acquired FHR tracings, 150 from antepartum high-risk pregnancies and 150 from unselected intrapartum cases, were presented to nine experienced clinicians included in three different groups, for an estimation of the FHR baseline. The first group consisted of clinicians using the proposed definition, without previous training in its use.
