Uterine Rupture associated with recent antepartum cocaine abuse.
Obstetrics & Gynecology, 1994Co-Authors: Brian Iriye, Regina Bruni, Robert E. Bristow, Timothy R B JohnsonAbstract:BACKGROUND: The diagnosis of Uterine Rupture is aided by the identification of risk factors, such as oxytocin administration. In several experiments, cocaine has been shown to stimulate Uterine contractility. Complications from cocaine abuse during pregnancy have increased dramatically in the United States, and cocaine may increase the risk for Uterine Rupture. CASES: Two cases of Uterine Rupture were associated with recent cocaine abuse. CONCLUSION: These cases and recent experiments on the effect of cocaine on the pregnant uterus suggest that antepartum cocaine abuse may increase the risk of Uterine Rupture.

Infant Outcome After Complete Uterine Rupture
Obstetrical & Gynecological Survey, 2018Co-Authors: Iqbal Al-zirqi, Anne Kjersti Daltveit, Siri VangenAbstract:Background Complete Uterine Rupture is a rare peripartum complication often associated with a catastrophic outcome for both mother and child. However, little has been written based on large data sets about maternal and infant outcome after complete Ruptures. This is partly due to the rarity of the event and the serious maternal and infant outcome; it is also partly due to the use of international diagnostic codes that do not differentiate between the less catastrophic partial Rupture and more catastrophic complete Uterine Rupture. As Uterine Rupture is expected to increase due to increased cesarean delivery rates worldwide, it is important to know more completely about the outcome following complete Uterine Rupture. Objective We sought to explore risk factors associated with poor infant outcome in cases of complete Uterine Rupture. Study Design This population-based study used data from the Medical Birth Registry of Norway, the Patient Administration System, and medical records. We included births with complete Uterine Rupture after start of labor in all maternity units in Norway during the period 1967 through 2008 (n = 244 births), identified among 2,455,797 births. Uterine Ruptures were identified and further studied through a review of medical records. We estimated the associations between infant outcomes and demographic and labor risk factors using logistic regression analyses. Odds ratios with 95% confidence intervals for each risk factor were determined after adjustment for demographic factors and period of birth. The main outcome measure was infant outcome: healthy infant, intrapartum/infant deaths, hypoxic ischemic encephalopathy, and admission to the neonatal intensive care unit. Results We identified 109 (44.7%) healthy infants, 56 (23.0%) infants needing neonatal intensive care unit admission, 64 (26.2%) intrapartum/infant deaths, and 15 (6.1%) infants with hypoxic ischemic encephalopathy. The highest number of intrapartum/infant deaths occurred in 1967 through 1977 (51.6%) and the fewest in 2000 through 2008 (15.0%). Unscarred Uterine Ruptures did not significantly increase intrapartum/infant deaths compared to scarred Uterine Ruptures. Placental separation and/or fetal extrusion had the highest odds ratio for intrapartum/infant deaths (odds ratio, 17.9; 95% confidence interval, 7.5–42.4). Time-to-delivery interval 30 minutes vs Conclusion Intrapartum/infant death after complete Uterine Rupture decreased significantly over the decades. Time to delivery >30 minutes and placental separation and/or fetal extrusion had the highest association with intrapartum/infant deaths after complete Uterine Rupture. Time to delivery

risk factors for complete Uterine Rupture
American Journal of Obstetrics and Gynecology, 2017Co-Authors: I Alzirqi, Babill Straypedersen, Lisa Forsen, Siri Vangen, Anne Kjersti DaltveitAbstract:Background Complete Uterine Rupture is a rare peripartum complication associated with a catastrophic outcome. Because of its rarity, knowledge about its risk factors is not very accurate. Most previous studies were small and over a limited time interval. Moreover, international diagnostic coding was used in most studies. These codes are not able to differentiate between the catastrophic complete type and less catastrophic partial type. Complete Uterine Rupture is expected to increase as the rate of cesarean delivery increases. Thus, we need more accurate knowledge about the risk factors for this complication. Objective The objective of the study was to estimate the incidence and risk factors for complete Uterine Rupture during childbirth in Norway. Study Design This population-based study included women that gave birth after starting labor in 1967–2008. Data were from the Medical Birth Registry of Norway and Patient Administration System, complemented with information from medical records. We included 1,317,967 women without previous cesarean delivery and 57,859 with previous cesarean delivery. The outcome was complete Uterine Rupture (tearing of all Uterine wall layers, including serosa and membranes). Risk factors were parameters related to demographics, pregnancy, and labor. Odds ratios for complete Uterine Rupture were computed with crude logistic regressions for each risk factor. Separate multivariable logistic regressions were performed to calculate the adjusted odds ratios and 95% confidence intervals. Results Complete Uterine Rupture occurred in 51 cases without previous cesarean delivery (0.38 per 10,000) and 122 with previous cesarean delivery (21.1 per 10,000). The strongest risk factor was sequential labor induction with prostaglandins and oxytocin, compared with spontaneous labor, in those without previous cesarean delivery (adjusted odds ratio, 48.0, 95% confidence interval, 20.5–112.3) and those with previous cesarean delivery (adjusted odds ratio, 16.1, 95% confidence interval, 8.6–29.9). Other significant risk factors for those without and with previous cesarean delivery, respectively, included labor augmentation with oxytocin (adjusted odds ratio, 22.5, 95% confidence interval, 10.9–41.2; adjusted odds ratio, 4.4, 95% confidence interval, 2.9–6.6), antepartum fetal death (adjusted odds ratio, 15.0, 95% confidence interval, 6.2–36.6; adjusted odds ratio, 4.0, 95% confidence interval, 1.1–14.2), and previous first-trimester miscarriages (adjusted odds ratio, 9.6, 95% confidence interval, 5.7–17.4; adjusted odds ratio, 5.00, 95% confidence interval, 3.4–7.3). After a previous cesarean delivery, the risk of Rupture was increased by an interdelivery interval Conclusion Sequential labor induction with prostaglandins and oxytocin and augmentation of labor with oxytocin are important risk factors for complete Uterine Rupture in intact and scarred uteri.

Uterine Rupture: trends over 40 years
BJOG : an international journal of obstetrics and gynaecology, 2015Co-Authors: Iqbal Al-zirqi, Lisa Forsen, Anne Kjersti Daltveit, Babill Stray-pedersen, Siri VangenAbstract:Objective To follow trends of Uterine Rupture over a period of 40 years in Norway. Design Population-based study using data from the Medical Birth Registry, the Patient Administration System, and medical records. Setting Norway. Sample Women giving birth in 21 maternity units in Norway during the period 1967–2008 (n = 1 441 712 maternities). Methods The incidence and outcomes of Uterine Rupture were compared across four decades: 1967–1977; 1978–1988; 1989–1999; and 2000–2008. Multivariable logistic regression was used to determine the odds ratio (OR) for Uterine Rupture in each decade compared with the second decade. Main outcome measure Trends in Uterine Rupture. Results We identified 359 Uterine Ruptures. The incidence rates per 10 000 maternities in the first, second, third, and fourth decade were 1.2, 0.9, 1.7, and 6.1, respectively. The ORs for complete and partial Ruptures in the fourth versus the second decade were 6.4 (95% confidence interval, 95% CI 3.8–10.8) and 7.2 (95% CI 4.2–12.3), respectively. Significant contributing factors to this increase were the higher rates of labour augmentation with oxytocin, scarred uteri from a previous caesarean section, and labour induction with prostaglandins or prostaglandins combined with oxytocin. After adjusting for risk factors, the ORs for complete and partial Ruptures were 2.2 (95% CI 1.3–3.8) and 2.8 (95% CI 1.6–4.8), respectively. Severe postpartum haemorrhage, hysterectomy, intrapartum death and infant death after complete Uterine Ruptures decreased significantly over time. Conclusions A sharply increasing trend of Uterine Rupture was found. Obstetric interventions contributed to this increase, but could not explain it entirely. Tweetable abstract A sharply increasing trend of Uterine Ruptures has been found in Norway in recent years.

Uterine Rupture after previous caesarean section
British Journal of Obstetrics and Gynaecology, 2010Co-Authors: I Alzirqi, Babill Straypedersen, Lisa Forsen, Siri VangenAbstract:Please cite this paper as: Al-Zirqi I, Stray-Pedersen B, Forsen L, Vangen S. Uterine Rupture after previous caesarean section. BJOG 2010;117:809–820. Objective To determine the risk factors, percentage and maternal and perinatal complications of Uterine Rupture after previous caesarean section. Design Population-based registry study. Population Mothers with births ≥28 weeks of gestation after previous caesarean section (n = 18 794), registered in the Medical Birth Registry of Norway, from 1 January 1999 to 30 June 2005. Methods Associations of Uterine Rupture with risk factors, maternal and perinatal outcome were estimated using cross-tabulations and logistic regression. Main outcome measure Odds of Uterine Rupture. Results A total of 94 Uterine Ruptures were identified (5.0/1000 mothers). Compared with elective prelabour caesarean section, odds of Rupture increased for emergency prelabour caesarean section (OR: 8.63; 95% CI: 2.6–28.0), spontaneous labour (OR: 6.65; 95% CI: 2.4–18.6) and induced labour (OR: 12.60; 95% CI: 4.4–36.4). The odds were increased for maternal age ≥40 years versus <30 years (OR: 2.48; 95% CI: 1.1–5.5), non-Western (mothers born outside Europe, North America or Australia) origin (OR: 2.87; 95% CI: 1.8–4.7) and gestational age ≥41 weeks versus 37–40 weeks (OR: 1.73; 95% CI: 1.1–2.7). Uterine Rupture after trial of labour significantly increased severe postpartum haemorrhage (OR: 8.51; 95% CI: 4.6–15.1), general anaesthesia exposure (OR: 14.20; 95% CI: 9.1–22.2), hysterectomy (OR: 51.36; 95% CI: 13.6–193.4) and serious perinatal outcome (OR: 24.51 (95% CI: 11.9–51.9). Induction by prostaglandins significantly increased the odds for Uterine Rupture compared with spontaneous labour (OR: 2.72; 95% CI: 1.6–4.7). Prelabour Ruptures occurred after latent Uterine activity or abdominal pain in mothers with multiple or uncommon Uterine scars. Conclusion Trial of labour carried greater risk and graver outcome of Uterine Rupture than elective repeated caesarean section, although absolute risks were low. A review of labour management and induction protocol is needed.
