Abstract Objective The aim of the study is to investigate the association between intrapartum administration of magnesium sulfate in women with hypertensive disorders of pregnancy and postpartum hemorrhage. Study Design This was a retrospective cohort study of women diagnosed with a hypertensive disorder of pregnancy who delivered singleton gestations >32 weeks at a single, large volume tertiary care center between January 2006 and February 2015. Women who received intrapartum magnesium sulfate for seizure prophylaxis were compared with women who did not receive intrapartum magnesium sulfate. The primary outcome was frequency of postpartum hemorrhage. Secondary outcomes included estimated blood loss, uterine atony, and transfusion of packed red blood cells. Bivariable analyses were used to compare the frequencies of each outcome. Multivariable logistic regression models examined the independent associations of magnesium sulfate with outcomes. Results Of 2,970 women who met inclusion criteria, 1,072 (36%) received intrapartum magnesium sulfate. Women who received magnesium sulfate were more likely to be nulliparous, publicly insured, of minority race or ethnicity, earlier gestational age at delivery, and undergo labor induction. The frequency of postpartum hemorrhage was significantly higher among women who received magnesium sulfate compared with those who did not (12.4 vs. 9.3%, p = 0.008), which persisted after controlling for potential confounders. Of secondary outcomes, there was no difference in estimated blood loss between women who did and did not receive magnesium sulfate (250 mL [interquartile range 250–750] vs. 250 mL [interquartile range 250–750], p = 0.446). However, compared with women who did not receive magnesium sulfate, women who received magnesium sulfate had a greater frequency of uterine atony (8.9 vs 4.9%, p < 0.001) and transfusion of packed red blood cells (2.0 vs. 0.8%, p = 0.008). These differences persisted after controlling for potential confounders. Conclusion Intrapartum magnesium sulfate administration to women with hypertensive disorders of pregnancy is associated with increased odds of postpartum hemorrhage, uterine atony, and red blood cell transfusion.

Background: Complex hepatic injuries grades IV—V are highly lethal. The objective of this study is to assess the multidisciplinary approach for their management and to evaluate if survival could be improved with this approach. Study Design: Prospective 54-month study of all patients sustaining hepatic injuries grades IV—V managed operatively at a Level I Trauma Center. Main outcome measure: survival. Statistical analysis: univariate and stepwise logistic regression. Results: Seventy-five patients sustained penetrating (47/63%) and blunt (28/37%) injuries. Seven (9%) patients underwent emergency department thoracotomy with a mortality of 100%. Out of the 75 patients, 52 (69%) sustained grade IV, and 23 (31%) grade V. The estimated blood loss was 3,539±-3,040 ml. The overall survival was 69%, adjusted survival excluding patients requiring emergency department thoracotomy was 76%. Survival stratified to injury grade: grade IV 42/52–81%, grade V 10/23–43%. Mortality grade IV versus V injuries (p <0.002; RR 2.94; 95% CI 1.52–5.70). Risk factors for mortality: packed red blood cells transfused in operating room (p=0.024), estimated blood loss (p<0.001), dysryhthmia (p<0.0001), acidosis (p=0.051), hypothermia (p=0.04). The benefit of angiography and angioembolization indicated: 12% mortality (2/17) among those that received it versus a 36% mortality (21/58) among those that did not (p=0.074; RR 0.32; 95% CI 0.08–1.25). Stepwise logistic regression identified as significant independent predictors of outcome: estimated blood loss (p=0.0017; RR 1.24; 95% CI 1.08–1.41) and number of packed red blood cells transfused in the operating room (p=0.0358; RR 1.16; 95% CI 1.01–1.34). Conclusions: The multidisciplinary approach to the management of these severe grades of injuries appears to improve survival in these highly lethal injuries. A prospective multi-institutional study is needed to validate this approach.

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.

Objective This study aimed to compare the effectiveness of sustained uterine compression versus uterine massage in reducing blood loos after a vaginal delivery. Study Design This was a prospective randomized trial conducted at the American University of Beirut Medical Center (AUBMC) between October 2015 and October 2017. Inclusion criteria were women with a singleton pregnancy at ≥36 weeks of gestation, with less than three previous deliveries, who were candidates for vaginal delivery. Participants were randomized into two groups, a sustained uterine compression group (group 1) and a uterine massage group (group 2). Incidence of postpartum hemorrhage (blood loss of ≥500 mL) was the primary outcome. We assumed that the incidence of postpartum hemorrhage at our institution is similar to previously published studies. A total of 545 women were required in each arm to detect a reduction from 9.6 to 4.8% in the primary outcome (50% reduction) with a one-sided α of 0.05 and a power of 80%. Factoring in a 10% dropout rate. Secondary outcomes were admission to intensive care unit (ICU), postpartum complications, drop in hemoglobin, duration of hospital stay, maternal pain, use of uterotonics, or of surgical procedure for postpartum hemorrhage. Results A total of 550 pregnant women were recruited, 273 in group 1 and 277 in group 2. There was no statistically significant difference in baseline characteristics between the two groups. Type of anesthesia, rate of episiotomy, lacerations, and mean birth weight were also equal between the groups. Incidence of the primary outcome was not different between the two groups (group 1: 15.5%, group 2: 15.4%; p = 0.98). There was no statistically significant difference in any of the secondary outcomes between the two groups, including drop in hemoglobin (p = 0.79). Conclusion There was no difference in blood loss between sustained uterine compression and uterine massage after vaginal delivery. Key Points

Background: Postpartum hemorrhage is a common and occasionally life-threatening complication of labor. Cesarean section is associated with more blood loss in compared to vaginal delivery. Despite, there is a trend for increasing cesarean section rates in both developed and developing countries thereby increasing the risk of morbidity and mortality, especially among anemic women. The objective of this study was to evaluate the effect of preoperative administration of intravenous Tranexamic acid on blood loss during and after elective cesarean section.Methods: This was a prospective, randomized controlled study with 160 eligible pregnant women of 37 or more period of gestation. They were all planned for elective cesarean section and were randomized into two groups either to receive 10ml (1gm) of Tranexamic acid intravenously or 10ml of normal saline. Blood loss was measured during and for 24 hours after operation.Results: The mean estimated blood loss was significantly lower in women treated with Tranexamic acid compared with women in the placebo group (392.13 ml±10.06 vs 498.69 ml±15.87, respectively; p<0.001). The mean difference in pre-operative and post-operative hemoglobin levels was statistically significant in the Tranexamic acid group than in the control group (0.31±0.18 vs 0.79±0.23, respectively; p<0.001).Conclusions: Pre-operative use of Tranexamic acid is associated with reduced blood loss during and after elective cesarean section. In a developing country like ours where postpartum hemorrhage is a major threat to the life of the mothers, it seems to be a promising option.

Abstract Background Platelet dysfunction is a common cause of bleeding, perioperative blood transfusion, and surgical re-exploration in cardiac surgical patients. We evaluated the effect of incorporating a platelet function analyzer utilizing impedance aggregometry (Multiplate, Roche, Munich, Germany) into our local transfusion algorithm on the rate of platelet transfusion and postoperative blood loss in patients undergoing coronary artery bypass grafting (CABG) surgery. Methods Data were collected on patients undergoing CABG surgery from January 2015 to April 2017. Patients who underwent surgery before and after introduction of this algorithm were classified into prealgorithm and postalgorithm groups, respectively. The primary outcome was the rate of platelet transfusion before and after implementation of the Multiplate-based transfusion algorithm. Secondary outcomes included transfusion rate of packed red blood cells, postoperative blood loss at 12 and 24 hours, length of stay in the intensive care unit, and the hospital and mortality. Results A total of 726 patients were included in this analysis with 360 and 366 patients in the pre- and postalgorithm groups, respectively. Transfusion rates of platelets (p = 0.01) and packed red blood cells (p = 0.0004) were significantly lower following introduction of the algorithm in patients (n = 257) who had insufficient time to withhold antiplatelet agents. Receiver operating characteristic curves defined optimal cutoff points of arachidonic acid and adenosine diphosphate assays on the Multiplate to predict future platelet transfusion were 23AU and 43AU, respectively. Conclusions The introduction of a Multiplate-based platelet transfusion algorithm showed a statistically significant reduction in the administration of platelets to patients undergoing urgent CABG surgery.

OBJECT The authors present a retrospective cohort study examining complications in patients undergoing surgery for craniosynostosis using both minimally invasive endoscopic and open approaches. METHODS Over the past 10 years, 295 nonsyndromic patients (140 undergoing endoscopic procedures and 155 undergoing open procedures) and 33 syndromic patients (endoscopic procedures in 10 and open procedures in 23) met the authors’ criteria. Variables analyzed included age at surgery, presence of a preexisting CSF shunt, skin incision method, estimated blood loss, transfusions of packed red blood cells, use of intravenous steroids or tranexamic acid, intraoperative durotomies, procedure length, and length of hospital stay. Complications were classified as either surgically or medically related. RESULTS In the nonsyndromic endoscopic group, the authors experienced 3 (2.1%) surgical and 5 (3.6%) medical complications. In the nonsyndromic open group, there were 2 (1.3%) surgical and 7 (4.5%) medical complications. Intraoperative durotomies occurred in 5 (3.6%) endoscopic and 12 (7.8%) open cases, were repaired primarily, and did not result in reoperations for CSF leakage. Similar complication rates were seen in syndromic cases. There was no death or permanent morbidity. Additionally, endoscopic procedures were associated with significantly decreased estimated blood loss, transfusions, procedure length, and length of hospital stay compared with open procedures. CONCLUSIONS Rates of intraoperative durotomies and surgical and medical complications were comparable between endoscopic and open techniques. This is the largest direct comparison to date between endoscopic and open interventions for synostosis, and the results are in agreement with previous series that endoscopic surgery confers distinct advantages over open surgery in appropriate patient populations.

Abstract Background Blood loss is one of the major problems during operations of spine fusion. Several blood-conservative measures were applied to reduce the incidence of blood loss—among them, acute hypervolemic hemodilution (AHH) and controlled hypotension (CH). This study was designed to detect the effect of combination of AHH with CH induced by remifentanil versus magnesium sulfate on the volume of blood loss, allogeneic blood transfusion, hemodynamics, coagulation, and electrolytes during operations for spine fusion which are risky operations with high incidence of blood loss and blood transfusion. Sixty patients scheduled for posterior fusion of the spine were randomly allocated into three groups of 20 patients each (group I (AHH), group II (AHH combined with remifentanil-based CH), and group III (AHH combined with magnesium sulfate-based CH)). Estimated blood loss and total volume of packed red blood cells (PRBCS) transfused were recorded. Arterial blood pressure (ABP) and heart rate (HR) measures were recorded. Blood samples were obtained for the detection of hemoglobin (Hb) and hematocrit (HCT). Results Estimated blood loss, percentage blood loss, and intraoperative RBC transfusion units were significantly high in group I in relation to group II and group III (Table 2). Cardiac output was significantly higher in group I in relation to group II and group III at 10, 15, 30, 45, and 60 min after start of AHH. MBP and HR results were significantly high in group I in comparison with group II and group III at 30, 45, 60, and 90 min and 2 and 3 h after start of study drugs. CVP results were significantly high in group I in relation to group II and group III at 15, 30, 45, 60, and 90 min after start of AHH. PTT was significantly increased in the three study groups in comparison with baseline inside each group after AHH. Conclusion Combination of AHH with CH induced by remifentanil or magnesium sulfate was associated with reduction in estimated blood loss, and total volume of PRBCS transfused. There was no significant difference between hemodynamic parameters with the use of remifentanil or magnesium sulfate except that SBP, DBP, and MBP results were significantly high with magnesium sulfate at 15 min after drug infusion. There was significant increase in PT and PTT after AHH that was not reflected by significant blood oozing from the operative field, or by difficulty in hemostasis.

Background: Postpartum hemorrhage (PPH) is a potentially life-threatening complication of both vaginal and caesarean delivery. The most frequent cause of postpartum hemorrhage is uterine atony, when the uterus fails to contract fully after delivery of the placenta. For the prevention of this uterine atony we need an effective uterotonic drug. Till now oxytocin is used for enhancing uterine contraction after delivery. But oxytocin has some limitations like shorter halflife, less contraction time and more side effects, whereas carbetocin has prolonged duration of action which ensures more contraction time and less adverse effects. So, carbetocin considered as a good alternative over oxytocin for the prevention of primary PPH in caesarean section. The Aim of Study: To see the efficacy and safety of carbetocin over oxytocin for the prevention of primary PPH during caesarean section. Patients and Methods: A randomized-controlled trial was conducted in the Institute of Child and Mother Health (ICMH), Dhaka, Bangladesh over a period of nine months from January to September 2016. Ninety-four patients who had got admitted in ICMH undergoing caesarean section at term were randomized into two groups receiving either 10IU oxytocin or 100μg carbetocin, after the operation. Outcome measures such as primary PPH, massive blood loss, need for additional uterotonic drug, additional blood transfusion as well as adverse effects were all documented. Results: This study had shown that carbetocin is superior in comparison to oxytocin for the prevention of primary PPH following caesarean section. Each patient obtained either a single dose of 100 microgram carbetocin intravenously or 10 IU of oxytocin during caesarean section. Massive blood loss occurred in 6.4%patients, blood transfusion needed in 17% patients and additional uterotonic needed for 25.5% patients in oxytocin group but in carbetocin group no massive blood loss occurred, only 2.1% patient needed immediate blood transfusion and no patient was required additional uterotonics. There were no major adverse effects observed in both the groups. No patients had developed PPH in carbetocin group. But 12.8% patients had developed primary PPH in oxytocin group. Conclusion: Carbetocin appears to be an effective new drug than oxytocin for the prevention of primary postpartum hemorrhage in caesarean section. J Bangladesh Coll Phys Surg 2019; 37(1): 19-24

Abstract Objectives To assess the applicability of a standardized multidisciplinary protocol for managing placenta accreta spectrum (PAS) disorders and its impact on the outcomes. Methods We compared patients with PAS manage by a standardized multidisciplinary protocol (T2) to historic controls managed on a case-by-case basis by individual physicians between (T1). The primary outcome is composite maternal morbidity. Secondary outcomes were the rates of surgical complications, estimated blood loss, number of blood products transfused, intensive care unit admissions, ventilator use, and birth weight. Multivariate logistic analysis was used to identify independent predictors of composite maternal morbidity. Results During T1 and T2, we managed 39 and 36 patients with confirmed PAS, respectively. During T2, the protocol could be implemented in 21 cases (58%). Compared to T1, patients managed during T2 had 70% less composite maternal morbidity (95% CI: 0.11–0.82) and lower blood loss (median, 2,000 vs. 1,100 mL, p=0.008). Also, they were 68% less likely to require transfusion of blood products (95% CI: 0.12–0.81; p=0.01), including fewer units of packed red blood cells (median, 2 vs. 0, p=0.02). Management following the protocol was the only independent factor associated with lower composite maternal morbidity (OR: 0.22; 95% CI: 0.05–0.95; p=0.04). Selected maternal and neonatal outcomes were not different among 12 and 15 patients with suspected but unconfirmed PAS disorders managed during T1 and T2, respectively. Conclusions Most patients can be managed under a standardized multidisciplinary protocol for PAS disorders, leading to improved outcomes.
