Intrauterine double-balloon tamponade vs gauze packing in the management of placenta previa: A multicentre randomized controlled trial.

ABSTRACT:

Background

To evaluate the effectiveness and safety of a newly designed intrauterine double-balloon catheter to arrest postpartum hemorrhage (PPH) following cesarean delivery (CD) for placenta previa.

Methods

We conducted an open-label, multicenter randomized controlled trial in two referral centers and one general hospital. Women with continuous bleeding after placental delivery following CD for placenta previa, who failed to respond to uterotonics, suturing and uterine devascularization, and in the absence of suspected deeply invasive accreta were eligible subjects. Eligible subjects were randomized to receive intrauterine double-balloon catheter (n?=?102) or gauze packing (n?=?102). The main outcome was the rate of successful hemostasis without the need for additional surgical interventions. The secondary outcomes included the volume of blood loss during and after CD, the rate of PPH, incidence and amount of blood transfusion, hysterectomy, surgical complications, intensive care unit admission, need for re-laparotomy, length of hospital stay, and readmission.

Results

The 224 participants were recruited before delivery, with 20 excluded (14 cases bleeding stopped after uterotonics and/or local myometrium sutures and 6 patients with placental increta). Finally, 102 women were assigned in catheter group and 102 others in gauze group. There was no difference in the rate of successful hemostasis in the catheter and gauze groups (93.1% vs 91.2%, P?=?.80). Compared with those in the gauze group, women in the catheter group showed significantly less blood loss within 24?hours postpartum (895 [612.3-1297.8] vs 1156 [882.5-1453.3] ml, P?ConclusionUterine tamponade using a double-balloon catheter was as effective as gauze packing in hemostasis, and appeared to be superior in reducing postpartum blood loss and pain following CD for placenta previa. Using double-balloon catheter in managing PPH in this situation may be a preferable alternative to minimize maternal morbidity.

Project description:Placenta previa and placenta accreta carry significant maternal and fetal morbidity and mortality. Several techniques have been described in the literature for controlling massive bleeding associated with placenta previa cesarean sections. The objective of this study was to evaluate the efficacy and safety of the use of the cervix as a natural tamponade in controlling postpartum hemorrhage caused by placenta previa and placenta previa accreta.This prospective study was conducted on 40 pregnant women admitted to our hospital between June 2012 and November 2014. All participating women had one or more previous cesarean deliveries and were diagnosed with placenta previa and/or placenta previa accreta. Significant bleeding from the placental bed during cesarean section was managed by inverting the cervix into the uterine cavity and suturing the anterior and/or the posterior cervical lips into the anterior and/or posterior walls of the lower uterine segment.The technique of cervical inversion described above was successful in stopping the bleeding in 38 out of 40 patients; yielding a success rate of 95%. We resorted to hysterectomy in only two cases (5%). The mean intra-operative blood loss was 1572.5 mL, and the mean number of blood units transfused was 3.1. The mean time needed to perform the technique was 5.4?±?0.6 min. The complications encountered were as follows: bladder injury in the two patients who underwent hysterectomy and wound infection in one patient. Postoperative fever that responded to antibiotics occurred in 1 patient. The mean duration of the postoperative hospital stay was 3.5 daysThis technique of using the cervix as a natural tamponade appears to be safe, simple, time-saving and potentially effective method for controlling the severe postpartum hemorrhage (PPH) caused by placenta previa/placenta previa accreta. This technique deserves to be one of the tools in the hands of obstetricians who face the life-threatening hemorrhage of placenta accreta.ClinicalTrials.gov NCT02590484 . Registered 28 October 2015.

Project description:Background Placenta previa accreta is a life-threatening pregnancy complication, and reducing blood loss during operative treatment remains a major challenge. The aim of our study was to investigate the effect of prophylactic abdominal aortic balloon occlusion (AABO) during caesarean section in women with placenta previa accreta. Methods A retrospective study of women with placenta previa accreta was conducted in a tertiary hospital from January 1, 2015, to December 31, 2020. Women were divided into balloon and control groups by whether AABO was performed. Baseline characteristics and pregnancy outcomes were compared in the two groups. A propensity score analysis was applied to minimise the indication bias. The primary outcome was composite, including estimated blood loss (EBL) ≥ 2.0 L, massive transfusion and hysterectomy. Results A total of 156 patients participated in this study, with 68 in the balloon group and 88 in the control group. Propensity score analysis showed that women in the balloon group had less EBL (1590.36 ± 1567.57 vs. 2830.36 ± 2285.58 mL, P = 0.02) as well as a lower proportion of EBL ≥ 1.0 L (50.00% vs. 78.57%, P = 0.03), EBL ≥ 2.0 L (21.43% vs. 50.00%, P = 0.03) and EBL ≥ 3.0 L (14.29% vs. 42.86%, P = 0.04). In addition, women in the control group received more red blood cell transfusions (8.43 U ± 9.96 vs. 3.43 U ± 6.27, P = 0.03), and the proportion of massive transfusions was higher (35.71% vs. 7.14%, P = 0.02). The proportions of disseminated intravascular coagulation (0% vs. 28.57%, P < 0.01), haemorrhagic shock (3.57% vs. 32.14%, P = 0.02) and hysterectomy (10.71% vs. 39.29%, P = 0.03) were significantly lower in the balloon group. Sutures were performed more often in the balloon group (64.29% vs. 17.86%, P < 0.01). Multivariate logistic regression analysis showed that AABO was associated with the primary outcome (adjusted odds ratio 0.46, 95% confidence interval 0.23 ~ 0.96, P = 0.04). No serious balloon catheter-related complications occurred in the balloon group. Conclusion AABO was an effective and safe approach to improve maternal outcomes for patients with placenta previa accreta.

Project description:BackgroundThe correlation between gestational hypertension-preeclampsia (GH-PE) and placenta previa (PP) is controversial. Specifically, it is unknown whether placenta previa has any effect on the various types of preeclampsia (PE), and the role PP with concurrent placenta accreta (PA) play in the occurrence of GH-PE are not well understood.ObjectiveThe aim of this study was to identify the effects of PP on GH, mild and severe preeclampsia (MPE and SPE), and early- and late-onset preeclampsia (EPE and LPE). Another aim of the study was to determine if concurrent PA impacts the relationship between PP and GH-PE.MethodsA retrospective single-center study of 1,058 patients having singleton pregnancies with PP was performed, and 2,116 pregnant women were randomly included as controls. These cases were collected from a tertiary hospital and met the inclusion criteria for the study. Clinical information, including PP and the gestational age at the onset of GH-PE were collected. Binary and multiple logistic regression analyses were conducted after the confounding variables were controlled to assess the effects of PP on different types of GH-PE.ResultsThere were 155 patients with GH-PE in the two groups. The incidences of GH-PE in the PP group and the control group were 2.5% (26/1058) and 6.1% (129/2116), respectively (P = 0.000). Binary and multiple regression analyses were conducted after controlling for confounding variables. Compared to the control group, in the PP group, the risk of GH-PE was reduced significantly by 78% (AOR: 0.216; 95% CI: 0.135-0.345); the risks of GH and PE were reduced by 55% (AOR: 0.451; 95% CI: 0.233-0.873) and 86% (AOR: 0.141; 95% CI: 0.073-0.271), respectively; the risks of MPE and SPE were reduced by 73% (AOR: 0.269; 95% CI: 0.087-0828) and 88% (AOR: 0.123; 95% CI: 0.055-0.279), respectively; and the risks of EPE and LPE were reduced by 95% (AOR: 0.047; 95% CI: 0.012-0.190) and 67% (AOR: 0.330; 95% CI: 0.153-0.715), respectively. The incidence of concurrent PA in women with PP was 5.86%; PP with PA did not significantly further reduce the incidence of GH-PE compared with PP without PA (1.64% vs. 2.51%, P>0.05). Binary logistic regression analyses were conducted after controlling for confounding variables, compared with the non-PP + GH-PE group, and the AOR of FGR in the non-PP + non-GH-PE group was 0.206 (0.124-0.342). Compared with the PP + GH-PE group, the AOR of FGR in the PP + non-GH-PE group was 0.430 (0.123-1.500).ConclusionPP is not only associated with a significant reduction in the incidence of GH-PE, but also is associated with a reduction in incidence of various types of PE. Concurrent PA and PP do not show association with a reduction in incidence of GH-PE.

Project description:BackgroundUterine incarceration is a rare obstetric complication that is always associated with retroversion and prone to misdiagnosis. Pelvic examination and imaging methods including ultrasound and magnetic resonance imaging (MRI) are used as the primary diagnostic tool. We present an asymptomatic anterior uterine incarceration complicated by placenta previa and placenta accreta spectrum (PAS) disorder, which could be diagnosed during the pregnancy periods, but was first diagnosed during the cesarean section (CS) and got the surgeons into trouble.Case descriptionA 28-year-old woman, gravidity 4, parity 1, was hospitalized due to placenta previa and PAS disorder diagnosed by ultrasound and MRI at 35.6 weeks of gestation. She had not experienced any discomfort. Given her history of a previous CS, she underwent a well-prepared cesarean delivery for the termination of the pregnancy. The patient had a series of periodical ultrasound and MRI examinations in which placenta previa and placenta accreta were described in disregard of the abnormal location of cervix; consequently, interior uterine incarceration was first diagnosed during the surgery, which caused significant difficulties in the operation which lasted 3 hours and 21 minutes. The patient developed severe hemorrhaging and lost approximately 5,000 mL of blood. Fortunately, she delivered a health male infant weighing 3,440 grams with quite good Apgar scores. During the follow-up, maternal and child health was confirmed.ConclusionsWith regard to patients who have undergone previous pelvic surgery, doctors need to pay close attention to the position of the cervix, the pelvic adhesion situation during the prenatal examination, and be on alert for uterine incarceration. Uterine incarceration can be accurately recognized by periodic sonography and MRI if the radiologist is aware of this unusual condition. We do suggest that special are must be taken to avoid unnecessary trauma by misdiagnosis because of lack of awareness.
