    Co-Authors: Junichi Hasegawa, Tomoaki Ikeda, Akihiko Sekizawa, Isamu Ishiwata, Tatsuya Arakaki, Katsuyuki Kinoshita
    Abstract:

    Aim To clarify whether the incidence of Umbilical Cord Prolapse (UCP) at delivery is related to the cervical ripening balloon (CRB). Methods A postal questionnaire study was conducted in 2018 in institutions providing maternity services across Japan. Questions on the number of deliveries, labor inductions, used CRB and cases of UCP in 2017 were included. Because a similar questionnaire survey was conducted in 2012, the incidence of UCP and frequency of the use of CRB were compared. Results A total of 1354 answers were assessed (57% of all delivery institutions). The total number of deliveries was 490 279. Of these, 78% were transvaginal; 74 cases of UCP were reported (0.015%), while 13 cases were reported from obstetric facilities never using CRB (0.008%). The incidence of UCP (odds ratio [95% confidence interval]) was 0.036% in the intracervical type (4.3 [1.6-11.3]), 0.091% in the disk-type (11.0 [4.2-29.0]) and 0.067% in the ball-type (8.1 [2.8-22.8]). Frequencies of the use of CRB were 7.3% and 6.6% in the 2012 and 2018 surveys, respectively. The use of the intracervical type increased from 2.8% in the 2012 survey to 3.5% in the 2018 survey, while that of the disk-type and ball-type declined. However, the incidence of UCP was not different between the two surveys regardless of the use of cervical ripening balloons (0.014% vs 0.015% with CRB, 0.005% vs 0.008% without CRB). Conclusion Although the frequency of CRB use significantly declined, the incidence of UCP did not significantly reduce in the last 5 years.

    Abstract:

    Objectives To demonstrate the clinical course and the obstetric risk factors for Umbilical Cord Prolapse. Methods The clinical course of reported cases of Umbilical Cord Prolapse that occurred in Japan between 2007 and 2011 was retrospectively analyzed. The obstetric risk factors for Umbilical Cord Prolapse were investigated by a nationwide population-based case-cohort study. Results Three hundred and sixty-nine cases (0.018 %) of fore-lying/Prolapsed Umbilical Cord in 2,037,460 deliveries were analyzed. Most cases of fore-lying Umbilical Cord were diagnosed by an ultrasound scan (78 %), whereas Umbilical Cord Prolapse was most frequently diagnosed by an internal examination (63 %). Umbilical Cord Prolapse was found to be significantly associated with the following factors: multiple pregnancy [odds ratio (OR) 3.57; 95 % confidence interval (CI) 2.60, 4.90], non-vertex presentation (OR 4.67; 95 %CI 3.73, 5.86), preterm labor (OR 2.28; 95 %CI 1.83, 2.83), premature rupture of membranes (OR 3.84; 95 %CI 3.10, 4.77), Prolapsed amniotic bag (OR 12.31; 95 %CI 9.00, 16.85), polyhydramnios (OR 2.89; 95 %CI 1.49, 5.61), and a birth weight of

    Abstract:

    AbstractObjectives: To clarify the clinical risk factors associated with poor neonatal outcomes due to Umbilical Cord Prolapse (UCP).Methods: A postal questionnaire survey was attempted in Japan. The clinical risk factors and managements associated with poor neonatal outcomes were analyzed in cases of UCP treated in Japan.Results: A total of 267 cases of UCP (out of 2 037 460 total deliveries) were analyzed. The rates of intrauterine death, neonatal death and survival with disability were 3.4%, 5.6% and 7.1%, respectively. The multivariate regression analysis for these poor neonatal outcomes revealed that the significant risk factors included a Prolapsed amniotic sac (adjusted odds ratio (aOR), 4.49), preterm labor (aOR, 2.99) and replacement of the Prolapsed Umbilical Cord into the uterus (aOR, 2.87). However, UCP that occurred during labor (aOR, 0.28) and emergency cesarean section (aOR, 0.11) were associated with a reduction in the rates of poor outcomes. The interval between the diagnosis of UCP and d...

  • The use of balloons for uterine cervical ripening is associated with an increased risk of Umbilical Cord Prolapse: population based questionnaire survey in Japan

    Abstract:

    Background To clarify whether the use of balloons for cervical ripening is associated with the incidence of Umbilical Cord Prolapse. Methods A postal questionnaire survey was distributed in Japan. Cases of Umbilical Cord Prolapse occurring during labor in association with the use of balloons for cervical ripening between 2007 and 2011 in Japan were analyzed. Results Answers from 942 institutions were obtained. The subjects included 369 patients with fore-lying or Prolapse of the Umbilical Cord among a total of 2,037,460 deliveries. Among the singleton vertex cases, fore-lying or Prolapse of the Umbilical Cord during labor were observed in 88 (0.005%) of 1,891,189 deliveries not associated with the use of balloons for cervical ripening and in 93 (0.064%) of 146,271 deliveries associated with the use of balloons for cervical ripening (Odds ratio 13.67, 95% confidence interval 10.21, 18.30). All types of balloons were significantly associated with the occurrence of fore-lying or Prolapse of the Umbilical Cord. A total of 39% of cases of Umbilical Cord Prolapse occurred during manual or spontaneous balloon removal, while 53% of cases occurred after a while not directly associated with balloon removal. Conclusion The risk of Umbilical Cord Prolapse was significantly increased during the use of balloons for cervical ripening, especially in cases involving the use of disk-type and ball-type balloons filled with large amounts of water.

    Abstract:

    Aim To clarify whether the incidence of Umbilical Cord Prolapse (UCP) at delivery is related to the cervical ripening balloon (CRB). Methods A postal questionnaire study was conducted in 2018 in institutions providing maternity services across Japan. Questions on the number of deliveries, labor inductions, used CRB and cases of UCP in 2017 were included. Because a similar questionnaire survey was conducted in 2012, the incidence of UCP and frequency of the use of CRB were compared. Results A total of 1354 answers were assessed (57% of all delivery institutions). The total number of deliveries was 490 279. Of these, 78% were transvaginal; 74 cases of UCP were reported (0.015%), while 13 cases were reported from obstetric facilities never using CRB (0.008%). The incidence of UCP (odds ratio [95% confidence interval]) was 0.036% in the intracervical type (4.3 [1.6-11.3]), 0.091% in the disk-type (11.0 [4.2-29.0]) and 0.067% in the ball-type (8.1 [2.8-22.8]). Frequencies of the use of CRB were 7.3% and 6.6% in the 2012 and 2018 surveys, respectively. The use of the intracervical type increased from 2.8% in the 2012 survey to 3.5% in the 2018 survey, while that of the disk-type and ball-type declined. However, the incidence of UCP was not different between the two surveys regardless of the use of cervical ripening balloons (0.014% vs 0.015% with CRB, 0.005% vs 0.008% without CRB). Conclusion Although the frequency of CRB use significantly declined, the incidence of UCP did not significantly reduce in the last 5 years.

    Abstract:

    Objectives To demonstrate the clinical course and the obstetric risk factors for Umbilical Cord Prolapse. Methods The clinical course of reported cases of Umbilical Cord Prolapse that occurred in Japan between 2007 and 2011 was retrospectively analyzed. The obstetric risk factors for Umbilical Cord Prolapse were investigated by a nationwide population-based case-cohort study. Results Three hundred and sixty-nine cases (0.018 %) of fore-lying/Prolapsed Umbilical Cord in 2,037,460 deliveries were analyzed. Most cases of fore-lying Umbilical Cord were diagnosed by an ultrasound scan (78 %), whereas Umbilical Cord Prolapse was most frequently diagnosed by an internal examination (63 %). Umbilical Cord Prolapse was found to be significantly associated with the following factors: multiple pregnancy [odds ratio (OR) 3.57; 95 % confidence interval (CI) 2.60, 4.90], non-vertex presentation (OR 4.67; 95 %CI 3.73, 5.86), preterm labor (OR 2.28; 95 %CI 1.83, 2.83), premature rupture of membranes (OR 3.84; 95 %CI 3.10, 4.77), Prolapsed amniotic bag (OR 12.31; 95 %CI 9.00, 16.85), polyhydramnios (OR 2.89; 95 %CI 1.49, 5.61), and a birth weight of

    Abstract:

    AbstractObjectives: To clarify the clinical risk factors associated with poor neonatal outcomes due to Umbilical Cord Prolapse (UCP).Methods: A postal questionnaire survey was attempted in Japan. The clinical risk factors and managements associated with poor neonatal outcomes were analyzed in cases of UCP treated in Japan.Results: A total of 267 cases of UCP (out of 2 037 460 total deliveries) were analyzed. The rates of intrauterine death, neonatal death and survival with disability were 3.4%, 5.6% and 7.1%, respectively. The multivariate regression analysis for these poor neonatal outcomes revealed that the significant risk factors included a Prolapsed amniotic sac (adjusted odds ratio (aOR), 4.49), preterm labor (aOR, 2.99) and replacement of the Prolapsed Umbilical Cord into the uterus (aOR, 2.87). However, UCP that occurred during labor (aOR, 0.28) and emergency cesarean section (aOR, 0.11) were associated with a reduction in the rates of poor outcomes. The interval between the diagnosis of UCP and d...

  • The use of balloons for uterine cervical ripening is associated with an increased risk of Umbilical Cord Prolapse: population based questionnaire survey in Japan

    Abstract:

    Background To clarify whether the use of balloons for cervical ripening is associated with the incidence of Umbilical Cord Prolapse. Methods A postal questionnaire survey was distributed in Japan. Cases of Umbilical Cord Prolapse occurring during labor in association with the use of balloons for cervical ripening between 2007 and 2011 in Japan were analyzed. Results Answers from 942 institutions were obtained. The subjects included 369 patients with fore-lying or Prolapse of the Umbilical Cord among a total of 2,037,460 deliveries. Among the singleton vertex cases, fore-lying or Prolapse of the Umbilical Cord during labor were observed in 88 (0.005%) of 1,891,189 deliveries not associated with the use of balloons for cervical ripening and in 93 (0.064%) of 146,271 deliveries associated with the use of balloons for cervical ripening (Odds ratio 13.67, 95% confidence interval 10.21, 18.30). All types of balloons were significantly associated with the occurrence of fore-lying or Prolapse of the Umbilical Cord. A total of 39% of cases of Umbilical Cord Prolapse occurred during manual or spontaneous balloon removal, while 53% of cases occurred after a while not directly associated with balloon removal. Conclusion The risk of Umbilical Cord Prolapse was significantly increased during the use of balloons for cervical ripening, especially in cases involving the use of disk-type and ball-type balloons filled with large amounts of water.
