Abstract Objective We evaluated risk factors to determine if there were specific risk factors that could predict massive bleeding in nulliparous women with placenta previa. Methods The participants were classified into two groups. Women with a calculated blood loss ≥ 1,000 mL were included in the massive bleeding group. Women without any signs or symptoms related with hypovolemia or with a calculated bleeding volume < 1,000 mL were categorized into the non-massive bleeding group. Results There were 28 patients (40.6%) with massive bleeding and 41 cases (59.4%) with non-massive bleeding. The calculated blood loss and number of cases that required red cell transfusions were statistically different between the groups (< 0.005 and 0.002, respectively). There were no statistically significant differences in terms of maternal or fetal factors, placental location, or delivery characteristics between the two groups. Conclusion We could not determine the predictive features for massive hemorrhage based on clinical features, delivery features, or placental location.

Increased Risk

Patients with placenta previa are at risk for intra- and postpartum massive blood loss as well as increased risk of placenta accreta, a type of abnormal placental implantation. This condition can lead to serious obstetric complications, including maternal mortality and morbidity. The risk factors for previa include prior cesarean section, multiparity, advanced maternal age, prior placenta previa history, prior uterine surgery, and smoking. The prevalence of previa parturients has increased due to the rising rates of cesarean section and advanced maternal age. For these reasons, we need to identify the risk factors for previa and identify adequate management strategies to respond to blood loss during surgery. This review evaluated the diagnosis of placenta previa and placenta accreta and assessed the risk factors for previa-associated bleeding prior to cesarean section. We then presented intraoperative anesthetic management and other interventions to control bleeding in patients with previa expected to experience massive hemorrhage and require transfusion.

Abstract Background A diagnostic sign on magnetic resonance imaging, suggestive of posterior extrauterine adhesion (PEUA), was identified in patients with placenta previa. However, the clinical features or surgical outcomes of patients with placenta previa and PEUA are unclear. Our study aimed to investigate the clinical characteristics of placenta previa with PEUA and determine whether an altered management strategy improved surgical outcomes. Methods This single institution retrospective study examined patients with placenta previa who underwent cesarean delivery between 2014 and 2019. In June 2017, we recognized that PEUA was associated with increased intraoperative bleeding; thus, we altered the management of patients with placenta previa and PEUA. To assess the relationship between changes in practice and surgical outcomes, a quasi-experimental method was used to examine the difference-in-difference before (pre group) and after (post group) the changes. Surgical management was modified as follows: (i) minimization of uterine exteriorization and adhesion detachment during cesarean delivery and (ii) use of Nelaton catheters for guiding cervical passage during Bakri balloon insertion. To account for patient characteristics, propensity score matching and multivariate regression analyses were performed. Results The study cohort (n = 141) comprised of 24 patients with placenta previa and PEUA (PEUA group) and 117 non-PEUA patients (control group). The PEUA patients were further categorized into the pre (n = 12) and post groups (n = 12) based on the changes in surgical management. Total placenta previa and posterior placentas were more likely in the PEUA group than in the control group (66.7% versus 42.7% [P = 0.04] and 95.8% versus 63.2% [P < 0.01], respectively). After propensity score matching (n = 72), intraoperative blood loss was significantly higher in the PEUA group (n = 24) than in the control group (n = 48) (1515 mL versus 870 mL, P < 0.01). Multivariate regression analysis revealed that PEUA was a significant risk factor for intraoperative bleeding before changes were implemented in practice (t = 2.46, P = 0.02). Intraoperative blood loss in the post group was successfully reduced, as opposed to in the pre group (1180 mL versus 1827 mL, P = 0.04). Conclusions PEUA was associated with total placenta previa, posterior placenta, and increased intraoperative bleeding in patients with placenta previa. Our altered management could reduce the intraoperative blood loss.

Emergency Peripartum Hysterectomy

Introduction: The aim of the research was to investigate incidence, risk factors, and complications associated with emergency peripartum hysterectomy, the ultimate treatment method for intractable postpartum hemorrhage.Methods: This is a single center case-control study conducted in Chongqing city in central China from 1st January 2007 to 31st December 2012 for emergency peripartum hysterectomy performed as a treatment of postpartum hemorrhage both in caesarean and vaginal delivery cases. While the study group included emergency peripartum hysterectomy (n=61) due to intractable postpartum hemorrhage, the control group included no hysterectomy (n=333) during the same study period.Results: We found 61 cases recorded for emergency peripartum hysterectomy for intractable postpartum hemorrhage. Incidence of peripartum hysterectomy was 2.2 per 1000 deliveries. Emergency peripartum hysterectomy as treatment of intractable postpartum hemorrhage include the followings: (i) blood loss 1000-2000 ml, crude odd ratio (OR) =18.48 (95% CI 5.1-65.7), adjusted odd ratio (AOR) = 9.1 (95% CI 2.2-37.7); (ii) blood loss >2000 ml, OR = 152 (95% CI 43.7-528.4), AOR = 45.3 (95% CI 11.6-176.9); (iii) previous caesarean section, OR = 5.5 (95% CI 2.9-9.7), AOR = 3.7(95% CI 1.4-9.9); (iv) uterine atony, OR = 11.9 (95% CI 5.8-24.6), AOR = 7.5 (95% CI 1.8-30.2); (v) placenta previa, OR = 2.04 (95% CI 1.1-3.5), AOR = none. Conclusions: Emergency peripartum hysterectomy is the last resort as treatment of intractable severe postpartum hemorrhage. Our study depicts that severe post partum hemorrhage, further dreaded complex events for emergency peripartum hysterectomy, has significant association with placental factors, previous caesarean section, and uterine atony. Pathologically, placenta accreta remained the most leading cause of hysterectomy.Keywords: caesarean section; hemorrhage; peripartum hysterectomy; placenta previa.

Stage Analysis

Massive hemorrhage and hemorrhagic shock as main causes of deaths in pregnancy, occupy up to 25% in the structure of mortality rate in obstetrics. In the past decade, the decline in the share of deaths of mothers has occurred due to postpartum bleedings and bleedings in detachment or placenta previa. The aim of the study was to determine the frequency and structure of massive bleedings in a high-risk group obstetric hospital. Methods. A retrospective descriptive cohort study was executed in 2 stages: at the 1st stage - a study of 396 deliveries histories with main nosological forms leading to possible pathological hemorrhage, in the II stage - analysis of 55 cases of massive blood loss. The object of the study was puerperas with placenta previa; puerperas with deliveries complicated by hypotonic bleeding or premature detachment of the placenta; puerperas with the massive blood loss. Duration of the study: from 01.01.2011 to 31.12. 2015. Results. The most frequent nosological form leading to abnormal blood loss is premature placental abruption. The frequency of cases of massive blood loss (more than 1000 ml) is 0.28% of the total number of deliveries and is more common in primigravidae (56.4%), mainly during surgical delivery (88%). Out of all massive bleedings, 45.5% are due to uterine hypotension. Amputation of the uterus was performed in 18.2% of the number of all cases of the massive hemorrhage. Conclusion. The high prevalence rate of the premature detachment of the placenta is explained by the uncontrollability of this pathology, in contrast to hypotonic bleeding in the postpartum period. The organ-preserving management in massive obstetric hemorrhages is not widely used.

Abstract Objectives To determine the rate of complicated birth at term in women classified at low risk according to the National Institute for Health and Care Excellence guideline for intrapartum care (no pre-existing medical conditions, important obstetric history, or complications during pregnancy) and to assess if the risk classification can be improved by considering parity and the number of risk factors. Design Cohort study using linked electronic maternity records. Participants 276 766 women with a singleton birth at term after a trial of labour in 87 NHS hospital trusts in England between April 2015 and March 2016. Main outcome measure A composite outcome of complicated birth, defined as a birth with use of an instrument, caesarean delivery, anal sphincter injury, postpartum haemorrhage, or Apgar score of 7 or less at five minutes. Results Multiparous women without a history of caesarean section had the lowest rates of complicated birth, varying from 8.8% (4879 of 55 426 women, 95% confidence interval 8.6% to 9.0%) in those without specific risk factors to 21.8% (613 of 2811 women, 20.2% to 23.4%) in those with three or more. The rate of complicated birth was higher in nulliparous women, with corresponding rates varying from 43.4% (25  805 of 59 413 women, 43.0% to 43.8%) to 64.3% (364 of 566 women, 60.3% to 68.3%); and highest in multiparous women with previous caesarean section, with corresponding rates varying from 42.9% (3426 of 7993 women, 41.8% to 44.0%) to 66.3% (554 of 836 women, 63.0% to 69.5%). Conclusions Nulliparous women without risk factors have substantially higher rates of complicated birth than multiparous women without a previous caesarean section even if the latter have multiple risk factors. Grouping women first according to parity and previous mode of birth, and then within these groups according to presence of specific risk factors would provide greater and more informed choice to women, better targeting of interventions, and fewer transfers during labour than according to the presence of risk factors alone.

Abstract Background Re-exploration of bleeding after cardiac surgery is associated with significant morbidity and mortality. Perioperative blood loss and rate of re-exploration are variable among centers and surgeons. Objective To present our experience of low rate of re-exploration based on adopting checklist for hemostasis and algorithm for management. Methods Retrospective analysis of medical records was conducted for 565 adult patients who underwent surgical treatment of congenital and acquired heart disease and were complicated by postoperative bleeding from Feb 2006 to May 2019. Demographics of patients, operative characteristics, perioperative risk factors, blood loss, requirements of blood transfusion, morbidity and mortality were recorded. Logistic regression was used to identify predictors of re-exploration and determinants of adverse outcome. Results Thirteen patients (1.14%) were reexplored for bleeding. An identifiable source of bleeding was found in 11 (84.6%) patients. Risk factors for re-exploration were high body mass index, high Euro SCORE, operative priority (urgent/emergent), elevated serum creatinine and low platelets count. Re-exploration was significantly associated with increased requirements of blood transfusion, adverse effects on cardiorespiratory state (low ejection fraction, increased s. lactate, and prolonged period of mechanical ventilation), longer intensive care unit stay, hospital stay, increased incidence of SWI, and higher mortality (15.4% versus 2.53% for non-reexplored patients). We managed 285 patients with severe or massive bleeding conservatively by hemostatic agents according to our protocol with no added risk of morbidity or mortality. Conclusion Low rate of re-exploration for bleeding can be achieved by strict preoperative preparation, intraoperative checklist for hemostasis implemented by senior surgeons and adopting an algorithm for management.

Angiographic Findings

Objective: We evaluated the risk factors for massive bleeding based on angiographic findings in patients with placenta previa and accreta who underwent balloon occlusion of the internal iliac artery (BOIA) during cesarean section. Methods: We performed a retrospective analysis using the clinical records of 42 patients with placenta previa and accreta who underwent BOIA during cesarean section between 2006 and 2017 in Gunma university hospital. We reviewed incidence of collateral arteries to the uterus on the initial aortography. We evaluated the visualization of the ovarian artery arising directly from the abdominal aorta, round ligament artery arising from the external iliac artery/inferior epigastric artery, and the iliolumbar artery. In addition, the clinical characteristics were reviewed. Patients with an estimated blood loss during delivery of >2500 ml, >4 packed red blood cell transfusions, uterine artery embolization after delivery, or hysterectomy were defined as the massive bleeding group. We compared between the massive and non-massive bleeding groups. Results: 20 patients (48%) had a massive bleeding. No procedure-related severe complications were observed. The massive and non-massive bleeding groups differed in terms of operation time (p < 0.001), hysterectomy (p < 0.001), post-operative hospital stay (p < 0.05), and visualization of round ligament arteries to the uterus [15/20 (75%) patients, p < 0.01]. Conclusion: The incidence of collateral blood supply from a round ligament artery to the uterus may be a risk factor for massive bleeding in patients with placenta previa and accreta who have undergone BOIA during cesarean section. Advances in knowledge: Angiographic visualization of collateral circulation from the round ligament artery to the uterus may be a risk factor for massive bleeding in patients with placenta previa and accreta who have undergone BOIA during cesarean section.

Cesarean Sections

Background and Objective: Blood loss in cesarean deliveries has already been established in previous researches but a detailed insight into the correlates has not been done. This study examined whether the number of previous Cesarean sections is related to the need for blood transfusion, and risk factors for blood transfusion. Methods: A retrospective review of 239 females who had undergone two or more Cesarean sections during the time period of 2015-2018 was done. Data collected included type of surgery (elective or emergency), age, parity, body mass index, estimated blood loss, operating time, level of surgeon, presence or absence of adhesions and number of transfused packed cell volume. Results: About 9.2% patients received blood transfusion with an estimated average blood loss of 618.18 ml. Patients with adhesions from previous surgery, presence of placenta previa, multiparity were significantly likely to receive blood transfusion. It was found that women with more than two caesarian sections had high proportion of blood transfusion as compared to women who had two caesarian sections. However non-significant difference was observed in numbers of caesarean sections with blood transfusion. Conclusion: Women undergoing Cesarean sections combined with any of the risk factors like increased body mass index, dense adhesions, uterine atony, hypertension and presence of placenta previa, were found to be at increased risk for a need for blood transfusions. doi: https://doi.org/10.12669/pjms.35.6.539 How to cite this:Abbas S, Mughal S, Hussain SNF, Hossain N.
