Hemorrhage remains a leading cause of preventable maternal morbidity and mortality worldwide and in the United States. Postpartum hemorrhage is the number one cause of severe morbidity during hospitalization for birth, despite hospital, state, and national initiatives. In addition, studies show that more than 90% of maternal deaths related to obstetric hemorrhage are preventable. This article reviews relevant physiologic changes of pregnancy that may have an impact on hemorrhage management and describes collaborative approaches for management of hemorrhage in this unique population.

Background Postpartum hemorrhage (PPH) is a major cause of maternal death worldwide. Management of PPH includes the administration of uterotonics, and intrauterine packing techniques. Objective In this study the effectiveness and safety of chitosan covered gauze versus a balloon tamponade for managing severe PPH should be assessed. Study design This retrospective cohort study was conducted at the Department of Obstetrics, Charite, university hospital Berlin, between October 2016 and June 2018. Women with PPH were treated according to management guidelines. When bleeding persisted, we applied additional uterine packing with either chitosan covered gauze or a balloon tamponade. The primary outcome was uterine bleeding termination without additional surgical interventions. Secondary outcomes included the amount of blood loss, the amount of blood transfusions and maternal complications. Results Among the 78 patients included in this study, 47 (60.3%) received chitosan covered gauze tamponade and 31 (39.7%) received a balloon tamponade. The major reason for PPH was atonic bleeding, no statistically significant group differences were observed. With respect to the outcomes monitored, the groups were not significantly different in postpartum vital signs, hemoglobin levels, blood loss, admission to intensive care unit, or inflammation parameters. However, three patients in balloon tamponade group required a hysterectomy. No hysterectomy was required in gauze group. Conclusion Chitosan covered gauze is an excellent option for treating PPH, it appeared to be at least equivalent to the balloon tamponade, in our experience particularly suitable for atony or placenta bed bleeding after spontaneous delivery or during cesarean sections, in cases of lower uterine segment atony, placenta previa bed bleeding, and/or coagulopathy.

Objective This study investigated the efficacy of GnRH agonists concomitantly with transient aromatase inhibitor and tranexamic acid to treat women with uterine arteriovenous malformations (AVMs) associated with abnormal uterine bleeding (AUB) to preserve fertility and determine reproductive outcome. Methods This was a prospective cohort study in a tertiary centre. Doppler ultrasound demonstrated AVM in 19 women with AUB 1–28 weeks following spontaneous or therapeutic abortion and in one woman 4 years after normal pregnancy while taking an oral contraceptive. On the basis of experience from the first three cases, 17 women were treated with tranexamic acid (1 g three times daily orally for 5 days), a GnRH agonist (3.75–11.25 mg, for 1–3 months), plus an aromatase inhibitor (letrozole 2.5 mg once daily for 5days) with the initial injection of GnRH agonist. Two women required blood transfusion, and one required uterine tamponade with Foley catheter balloon in the first 48 hours to control heavy bleeding (Canadian Task Force Classification II-2). Results All 20 AVMs resolved within 1–3 months of treatment. Of 16 women who attempted pregnancy, all (100%), including two who had uterine artery embolization (one after hysteroscopic septoplasty), conceived spontaneously with 18 live births. Two women are using contraception (one taking an oral contraceptive, one using a levonorgestrel intrauterine system), and one 40-year-old is not using contraception. One woman had hysteroscopic endometrial ablation followed by vaginal hysterectomy for AUB at 1 and 2 years later. Conclusion A GnRH agonist in combination with transient aromatase inhibitor and tranexamic acid is an effective management strategy to treat and maintain reproduction in women with AVMs associated with AUB.

Objective This study sought to investigate the effect of Bakri balloon use and vaginal tamponade combined with abdominal compression for the management of postpartum hemorrhage (PPH). Methods This retrospective study reviewed cases of PPH in the International Peace Maternal and Child Health Hospital of China Welfare Institution in Shanghai, China from January 1, 2010 to December 31, 2015. A single use of the intrauterine Bakri balloon was applied in some cases, and additional vaginal tamponade combined with abdominal compression (double compression) was applied in other cases. The authors evaluated the effect of these two methods in the management of PPH. Results The Bakri balloon was used in 305 cases of intrauterine PPH, and the clinical efficacy was 93.26%. One group of study patients underwent double compression, and these patients had a better clinical efficacy rate of 96.3% (157 of 163), whereas the efficacy in cases using the Bakri balloon alone (control group) was 87.3% (124 of 142). The postoperative complication rates of these two groups were 9.4% and 8.7%, respectively. Uterine arterial embolization was performed in patients in whom Bakri balloon use failed. None of the cases resulted in a hysterectomy. Conclusion Intrauterine Bakri balloon use combined with vaginal tamponade and abdominal compression is more effective in the treatment of PPH compared with Bakri balloon use alone. This method does not increase postoperative complications. Uterine atony with placenta previa or implantation may be possible reasons for noneffectiveness of Bakri balloon use.

Objective Rupture of uterine artery pseudoaneurysm (UAP) is a life-threatening event after childbirth. Hysterectomy or uterine arterial embolization was often needed for hemostasis. However, such procedures may cause severe morbidities for these women. To estimate the efficacy of uterine balloon tamponade (UBT) for controlling ruptured UAP bleeding, a retrospective analysis in a single teaching hospital was performed. Materials and methods We reviewed the medical record of Juntendo University Hospital in 2015. All the women diagnosed with UAP were recruited to this study and management for UAP was investigated. Results Three women were treated with UBT for ruptured UAP. All cases achieved hemostasis. One case had recurrent UAP after 24 h of UBT, and was retreated with UBT for a longer duration. The UAP was obliterated after more than 2 days of UBT in all cases. Conclusion UBT has potential as a therapeutic technique not only for treatment of a ruptured UAP but also for obliteration of a UAP.

Objective To assess the efficacy, effectiveness, and safety of uterine balloon tamponade for treating postpartum hemorrhage. Study Design We searched electronic databases (from their inception to August 2019) and bibliographies. We included randomized controlled trials, nonrandomized studies, and case series that reported on the efficacy, effectiveness, and/or safety of uterine balloon tamponade in women with postpartum hemorrhage. The primary outcome was the success rate of uterine balloon tamponade for treating postpartum hemorrhage (number of uterine balloon tamponade success cases/total number of women treated with uterine balloon tamponade). For meta-analyses, we calculated pooled success rate for all studies, and relative risk with 95% confidence intervals for studies that included a comparative arm. Results Ninety-one studies, including 4729 women, met inclusion criteria (6 randomized trials, 1 cluster randomized trial, 15 nonrandomized studies, and 69 case series). The overall pooled uterine balloon tamponade success rate was 85.9% (95% confidence interval, 83.9–87.9%). The highest success rates corresponded to uterine atony (87.1%) and placenta previa (86.8%), and the lowest to placenta accreta spectrum (66.7%) and retained products of conception (76.8%). The uterine balloon tamponade success rate was lower in cesarean deliveries (81.7%) than in vaginal deliveries (87.0%). A meta-analysis of 2 randomized trials that compared uterine balloon tamponade vs no uterine balloon tamponade in postpartum hemorrhage due to uterine atony after vaginal delivery showed no significant differences between the study groups in the risk of surgical interventions or maternal death (relative risk, 0.59; 95% confidence interval, 0.02–16.69). A meta-analysis of 2 nonrandomized before-and-after studies showed that introduction of uterine balloon tamponade in protocols for managing severe postpartum hemorrhage significantly decreased the use of arterial embolization (relative risk, 0.29; 95% confidence interval, 0.14–0.63). A nonrandomized cluster study reported that use of invasive procedures was significantly lower in the perinatal network that routinely used uterine balloon tamponade than that which did not use uterine balloon tamponade (3.0/1000 vs 5.1/1000; P Conclusion Uterine balloon tamponade has a high success rate for treating severe postpartum hemorrhage and appears to be safe. The evidence on uterine balloon tamponade efficacy and effectiveness from randomized and nonrandomized studies is conflicting, with experimental studies suggesting no beneficial effect, in contrast with observational studies. Further research is needed to determine the most effective programmatic and healthcare delivery strategies on uterine balloon tamponade introduction and use.

This article proposes a counter-argument to standard Advanced Trauma Life Support (ATLS) training--which advocates bladder catheterisation to be performed as an adjunct to the primary survey and resuscitation for early decompression of the bladder and urine output monitoring. We argue the case for delaying bladder catheterisation until after definitive truncal Computed Tomography (CT) imaging. To reduce pelvic volume and associated bleeding, our trauma team delay catheter insertion until after the initial CT scan. The benefits of a full bladder also include improved views on initial Focussed Assessment with Sonography in Trauma (FAST) scan and improved interpretation of injuries on CT. Our urinary catheter related infection rates anecdotally decreased when insertion was delayed and consequently performed in a more controlled, non-resuscitation setting following CT. Adult blunt multitrauma patients with pelvic ring fractures are at risk of significant haemorrhage. Venous, arterial and medullary injuries with associated bleeding may be potentiated by an increased pelvic volume with ring disruption, as well as a reduced pressure effect from retroperitoneal and intra-pelvic organs on bleeding sites. Various techniques are used to reduce intra-pelvic bleeding. For shocked patients who have sustained major pelvic injuries with no other signs of urinary tract trauma and minimal urine in the bladder on initial FAST scan, we advocate careful, aseptic Foley catheter insertion followed by bladder insufflation with 500-600 mL of Normal Saline (NS) and subsequent catheter clamping to tamponade pelvic bleeding.

Cervical ectopic pregnancy is uncommon, with no universally accepted protocol for conservative management of acute hemorrhage due to residual cervical ectopic pregnancy. Herein is presented the case of a 33-year-old woman with profuse vaginal bleeding 3 months after receiving treatment including intraamniotic potassium chloride injection, systemic methotrexate, and uterine artery embolization because of a cervical ectopic pregnancy. A residual cervical pregnancy was suspected. Hemorrhage was controlled using curettage, tamponade with a Bakri balloon, and cerclage. The balloon and cerclage were removed on postoperative day 2, with no recurrence of symptoms. Our experience suggests that a combination of curettage, balloon tamponade, and cerclage may be considered in the management of cervical ectopic pregnancies with acute hemorrhage, in particular in patients desiring future childbearing.

Morbidly adherent placenta refers to an abnormal invasion of the placental tissue (trophoblasts) into inner or outer myometrium or through the serosa of the uterus (termed accreta, increta or percreta, respectively.) Morbidly adherent placenta is associated with significant maternal morbidity and mortality, with a reported worldwide maternal mortality of 7%–10%. It increases the risk of massive obstetric haemorrhage and current management options for this potentially life-threatening condition include radical surgery such as elective peripartum hysterectomy with or without bowel/bladder resection or ureteric re-implantation (for placenta percreta infiltrating these organs) and conservative surgical measures such as myometrial compression sutures with uterine balloon tamponade. Intentional retention of the placenta may be needed in some patients where radical procedures are not appropriate or are refused by the patient in view of desire for future fertility. Unfortunately, both intentional retention of the placenta and peripartum hysterectomy may lead to serious maternal morbidity and mortality. Recently, a conservative surgical technique called the ‘Triple P Procedure' which involves p eri-operative placental localization and delivery of the fetus via transverse uterine incision above the upper border of the placenta; p elvic devascularization; and p lacental non-separation with myometrial excision and reconstruction of the uterine wall has been described as a safe and effective alternative to intentional retention of the placenta or peripartum hysterectomy.

Objective To evaluate the success rate of the Bakri balloon in the event of uncontrollable hemorrhage due to placenta previa. Study design We evaluated 25 patients who were treated with the Bakri balloon who had severe postpartum hemorrhage with placenta previa and failed medical treatment with uterotonic agents. Results The Bakri balloon was inserted abdominally during cesarean section in 24 of 25 cases. In only one case was it inserted vaginally. The Bakri tamponade was effective in 22 cases (88%). There were three cases with failure: two patients needed an additional procedure (hypogastric artery ligation and B-Lynch suture) and one patient needed hysterectomy. Conclusions The Bakri balloon is the least invasive, rapid method in the management of bleeding due to placenta previa with minimal complications.

Massive obstetric haemorrhage is a major contributor towards maternal morbidity and mortality. The main causes are abruptio placentae, placenta praevia and postpartum haemorrhage. Clinicians managing pregnant women should be equipped with the knowledge and skills for managing massive obstetric haemorrhage to institute timely and appropriate life-saving treatment. Prompt resuscitation and reversal of coagulopathy are critical while definitive measures are carried out to arrest the bleeding. Massive antepartum haemorrhage necessitates deliveries whereas interventions for postpartum haemorrhage range from medical to surgical measures. Algorithms such as haemostasis are useful aids to the systematic and stepwise management of postpartum haemorrhage. Surgical measures used to avoid peripartum haemorrhage include uterine compression sutures, uterine balloon tamponade, uterine artery, and internal iliac artery ligation. Tranexamic acid and recombinant factor VII are more recent medical interventions in massive postpartum haemorrhage. Education, regular drills and adherence to guidelines and protocols are important to reduce haemorrhage-related maternal deaths.

In cases of serious bleeding postpartum, resuscitation and surgical techniques are complementary and should be adapted to both the etiology and severity of bleeding. In extremely severe cases, the performance of a hysterectomy should not be delayed. For women with stable hemodynamic status, so-called "conservative" surgical techniques can instead be used. In this study, we describe and discuss the indications and feasibility of various techniques of vascular ligation. Uterine mattress suture compression techniques and abdomino-pelvic packing are also described. When conservative management is feasible, the first line approach should be bilateral distal ligation of the uterine arteries: this simple and low-risk technique is immediately effective in 80% of cases. If bleeding persists, uterine devascularization can be completed by a triple ligation as described by Tsirulnikov, with or without supplemental proximal ligation of the uterine arteries. This procedure should be performed in preference to the so-called "stepwise ligation sequence", which involves ligation of the ovarian pedicles and poses a risk of subsequent ovarian failure. Bilateral hypogastric artery ligation is also an effective and widely used first-line technique for experienced surgeons. This approach is technically challenging for less-experienced surgeons and is reserved for cases of failed triple ligation.

Objective We sought to determine whether the timing of balloon tamponade (BT) and uterine artery embolization is associated with morbidity among women with postpartum hemorrhage (PPH). Study Design This is a cohort study of women with PPH at a single tertiary academic institution. Patient demographics, delivery outcomes (eg, labor augmentation, route of delivery), and PPH-specific data (eg, estimated blood loss at the time when PPH interventions were employed) were abstracted from the chart. Outcomes studied included nadir hemoglobin, packed red blood cell transfusion, intensive care unit admission, and hysterectomy. Results During the study period, 420 women were eligible for analysis. Women receiving BT at lower estimated blood loss quartiles had higher nadir hemoglobin, less frequent packed red blood cell transfusion, fewer intensive care unit admissions, and fewer hysterectomies. There were no associations found between timing of uterine artery embolization and maternal outcomes. Conclusion Earlier use of BT among women experiencing a PPH is associated with decreased maternal morbidity.

We sought to determine whether the introduction of a postpartum hemorrhage (PPH) safety program was associated with changes in clinical practice and outcomes, and to examine whether these changes were sustained over time. In August 2008, a multidisciplinary PPH patient safety program was implemented at our single tertiary care hospital. We performed a cohort study of all women with PPH from August 2007 through December 2011. Changes in clinical practice and outcomes were compared before and after the intervention. Shewhart charts were used to examine sustainability of these changes over time. During the study period 52,819 women delivered, and 3105 (5.9%) experienced PPH. After the introduction of the program there was a significant increase in the use of uterotonic medications (P.001), intrauterine balloon tamponade (P = .002), B-Lynch suture placement (P = .042), uterine artery embolization (P = .050), and cryoprecipitate use (P = .0222). Concomitantly, the number of days between admissions to the intensive care unit for PPH increased.

Objective When uterotonics fail to cause sustained uterine contractions and satisfactory control of hemorrhage after delivery, tamponade of the uterus can be effective in decreasing hemorrhage secondary to uterine atony. Study Design These data are from a postmarketing surveillance study of a novel dual-balloon catheter tamponade device, the Belfort-Dildy Obstetrical Tamponade System (ebb). Results A total of 57 women were enrolled: 55 women had the diagnosis of postpartum hemorrhage, and 51 women had uterine balloon placement within the uterine cavity. This study reports the outcomes in the 51 women who had uterine balloon placement within the uterine cavity for treatment of postpartum hemorrhage, as defined by the "Instructions for Use." We further assessed 4 subgroups: uterine atony only (n = 28 women), placentation abnormalities (n = 8 women), both uterine atony and placentation abnormalities (n = 9 women), and neither uterine atony nor placentation abnormalities (n = 6 women). The median (range) time interval between delivery and balloon placement was 2.2 hours (0.3–210 hours) for the entire cohort (n = 51 women) and 1.3 hours (0.5–7.0 hours) for the uterine atony only group (n = 28 women). Bleeding decreased in 22/51 of cases (43%), stopped in 28/51 of cases (55%), thus decreased or stopped in 50/51 of the cases (98%) after balloon placement. Nearly one-half (23/51) of all women required uterine balloon volumes of >500 mL to control bleeding. Conclusion We conclude that uterine/vaginal balloon tamponade is very useful in the management of postpartum hemorrhage because of uterine atony and abnormal placentation.

Objective The objective of the study was to compare outcomes between patients who did and did not receive preoperative uterine artery balloon catheters in the setting placenta accreta. Study Design This was a retrospective case-control study of patients with placenta accreta from 1990 to 2011. Results Records from 117 patients with pathology-proven accreta were reviewed. Fifty-nine patients (50.4%) had uterine artery balloons (UABs) placed preoperatively. The mean estimated blood loss (EBL) was lower (2165 mL vs 2837 mL; P = .02) for the group that had UABs compared with the group that did not. There were more cases with an EBL greater than 2500 mL and massive transfusions of packed red blood cells (>6 units) in the group that did not have UABs. Percreta was diagnosed more often on final pathology in the group with UABs. Surgical times did not differ between the 2 groups. Two patients (3.3%) had complications related to the UABs. Conclusion Preoperative placement of UABs is relatively safe and is associated with a reduced EBL and fewer massive transfusions compared with a group without UABs.
