Abstract
OBJECTIVE To evaluate patient safety, resource utilization, and transfusion-related cost after a policy change from universal type and screen to selective type and screen on admission to labor and delivery. METHODS Between October 2017 and September 2019, we performed a single-center implementation study focusing on risk-based type and screen instead of universal type and screen. Implementation of our policy was October 2018 and compared 1 year preimplementation with 1 year postimplementation. Patients were risk-stratified in alignment with California Maternal Quality Care Collaborative recommendations. Under the new policy, the blood bank holds a blood sample for processing (hold clot) on patients at low- and medium-risk of hemorrhage. Type and screen and crossmatch are obtained on high-risk patients or with a prior positive antibody screen. We collected patient outcomes, safety and cost data, and compliance and resource utilization metrics. Cost included direct costs of transfusion-related testing in the labor and delivery unit during the study period, from a health system perspective. RESULTS In 1 year postimplementation, there were no differences in emergency-release transfusion events (4 vs 3, P>.99). There were fewer emergency-release red blood cell (RBC) units transfused (9 vs 24, P=.002) and O-negative RBC units transfused (8 vs 18, P=.016) postimplementation compared with preimplementation. Hysterectomies (0.05% vs 0.1%, P=.44) and intensive care unit admissions (0.45% vs 0.51%, P=.43) were not different postimplementation compared with preimplementation. Postimplementation, mean monthly type and screen-related costs (ABO typing, antibody screen, and antibody workup costs) were lower, $9,753 compared with $20,676 in the preimplementation year, P<.001. CONCLUSION Implementation of selective type and screen policy in the labor and delivery unit was associated with projected annual savings of $181,000 in an institution with 4,000 deliveries per year, without evidence of increased maternal morbidity.

Abstract
PURPOSE OF REVIEW Major obstetric hemorrhage is a leading cause of maternal morbidity and mortality. We will review transfusion strategies and the value of monitoring the maternal coagulation profile during severe obstetric hemorrhage. RECENT FINDINGS Epidemiologic studies indicate that rates of severe postpartum hemorrhage (PPH) in well resourced countries are increasing. Despite these increases, rates of transfusion in obstetrics are low (0.9-2.3%), and investigators have questioned whether a predelivery 'type and screen' is cost-effective for all obstetric patients. Instead, blood ordering protocols specific to obstetric patients can reduce unnecessary antibody testing. When severe PPH occurs, a massive transfusion protocol has attracted interest as a key therapeutic resource by ensuring sustained availability of blood products to the labor and delivery unit. During early postpartum bleeding, recent studies have shown that hypofibrinogenemia is an important predictor for the later development of severe PPH. Point-of-care technologies, such as thromboelastography and rotational thromboelastometry, can identify decreased fibrin clot quality during PPH, which correlate with low fibrinogen levels. SUMMARY A massive transfusion protocol provides a key resource in the management of severe PPH. However, future studies are needed to assess whether formula-driven vs. goal-directed transfusion therapy improves maternal outcomes in women with severe PPH.

Abstract
Women undergoing elective caesarean section (CS) routinely have a group and save ordered as part of their preoperative assessment, whereas women with expected vaginal birth do not. Our aim was therefore to determine the rate of blood transfusion at elective CS compared with vaginal birth in a large Australian maternity hospital. A retrospective cohort study was performed using routinely collected de-identified data of 35 477 women, over 4 years, who delivered at the Mater Mothers' Hospital, Brisbane, Australia. After excluding women with established risk factors for transfusion, the likelihood of blood transfusion following elective CS was significantly lower compared to vaginal birth (aOR 0.47 (0.29, 0.77)).

Abstract
BACKGROUND Haemorrhage from obstetric causes is the most common cause of maternal mortality in the developing world. Prevention of mortality from haemorrhage will necessarily involve prompt blood transfusions among other life saving measures. There are however limited stocks of fresh or stored blood in many health care facilities in Sub Saharan Africa. Caesarean section has been identified as a common indication for blood transfusion in obstetrics practice and its performance is often delayed by non availability of blood in our centre. An evaluation of blood reservation and use at caesarean sections in a tertiary maternity unit in Lagos, south western Nigeria should therefore assist in formulating the most rational blood transfusion policies. METHODS Case records of 327 patients who had elective and emergency caesarian sections at the Lagos State University Teaching Hospital between 1st October and 31st December 2007 were reviewed. Data pertaining to age, parity, booking status, type and indication for Caesarean section, pre- and post-operative packed cell volume, blood loss at surgery, units of blood reserved in the blood bank, unit(s) of blood transfused and duration of hospital stay was extracted and the data analysed. RESULTS There were 1056 deliveries out of which 327 (31%) were by Caesarean section. During the study period, a total of 654 units of blood were reserved in the blood bank and subsequently made available in theatre. Out of this number, only 89 (13.6%) were transfused to 41 patients. Amongst those transfused, twenty-six (54%) were booked and 31 (75.6%) had primary caesarian section. About 81% of those transfused had emergency caesarean section. The most common indication for surgery among those transfused were placenta praevia (9 patients with 21 units of blood) and cephalo-pelvic disproportion (8 patients with 13 units). CONCLUSION Even though a large number of units of blood was reserved and made available in the theatre at the time of operation, majority of the patients operated did not need blood transfusion. Provision of a mini- blood bank within the obstetric unit and careful patient categorization will ensure timely availability of blood for surgery without necessarily tying down stock in the central blood bank.

Abstract
BACKGROUND Rates of caesarean section (CS) have been rising globally. It is important to use the most effective and safe technique. OBJECTIVES To compare the effects of complete methods of caesarean section; and to summarise the findings of reviews of individual aspects of caesarean section technique. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (August 2007), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2007, Issue 3) and reference lists of identified papers. SELECTION CRITERIA Randomised controlled trials of intention to perform caesarean section using different techniques. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies and extracted data. MAIN RESULTS 'Joel-Cohen based' compared with Pfannenstiel CS was associated with: less blood loss, (five trials, 481 women; weighted mean difference (WMD) -64.45 ml; 95% confidence interval (CI) -91.34 to -37.56 ml); shorter operating time (five trials, 581 women; WMD -18.65; 95% CI -24.84 to -12.45 minutes); postoperatively, reduced time to oral intake (five trials, 481 women; WMD -3.92; 95% CI -7.13 to -0.71 hours); less fever (eight trials, 1412 women; relative risk (RR) 0.47; 95% CI 0.28 to 0.81); shorter duration of postoperative pain (two comparisons from one trial, 172 women; WMD -14.18 hours; 95% CI -18.31 to -10.04 hours); fewer analgesic injections (two trials, 151 women; WMD -0.92; 95% CI -1.20 to -0.63); and shorter time from skin incision to birth of the baby (five trials, 575 women; WMD -3.84 minutes; 95% CI -5.41 to -2.27 minutes). Serious complications and blood transfusions were too few for analysis.Misgav-Ladach compared with the traditional method (lower midline abdominal incision) was associated with reduced: blood loss (339 women; WMD -93.00; 95% CI -132.72 to -53.28 ml); operating time (339 women; WMD-7.30; 95% CI -8.32 to -6.28 minutes); time to mobilisation (339 women; WMD -16.06; 95% CI -18.22 to -13.90 hours); and length of postoperative stay for the mother (339 women; WMD -0.82; 95% CI -1.08 to -0.56 days). Misgav-Ladach compared with modified Misgav-Ladach methods was associated with a longer time from skin incision to birth of the baby (116 women; WMD 2.10; 95% CI 1.10 to 3.10 minutes). AUTHORS' CONCLUSIONS 'Joel-Cohen based' methods have advantages compared to Pfannenstiel and to traditional (lower midline) CS techniques, which could translate to savings for the health system. However, these trials do not provide information on mortality and serious or long-term morbidity such as morbidly adherent placenta and scar rupture.

Abstract
OBJECTIVE To evaluate risks for intraoperative or postoperative packed red blood cell transfusion in women who underwent cesarean delivery. METHODS This was a 19-university prospective observational study. All primary cesarean deliveries from January 1, 1999, to December 31, 2000, and all repeat cesareans from January 1, 1999, to December 31, 2002, were included. Trained, certified research nurses performed systematic data abstraction. Primary and repeat cesarean deliveries were analyzed separately. Univariable analyses were used to inform multivariable analyses. RESULTS A total of 23,486 women underwent primary cesarean delivery, of whom 762 (3.2%) were transfused (median 2 units, 25th% to 75th% 2-3 units). A total of 33,683 women underwent repeat [corrected] cesarean delivery, and 735 (2.2%) were transfused (median 2 units, 25th% to 75th% 2-4 units). Among primary cesareans, general anesthesia (odds ratio [OR] 4.2, 95% confidence interval [CI] 3.5-5.0), placenta previa (OR 4.8, CI 3.5-6.5) and severe (hematocrit less than 25%) preoperative anemia (OR 17.0, CI 12.4-23.3) increased the odds of transfusion. Among repeat cesareans, the risk was increased by general anesthesia (OR 7.2, CI 5.9-8.7), a history of five or more prior cesareans (OR 7.6, CI 4.0-14.3), placenta previa (OR 15.9, CI 12.0-21.0), and severe preoperative anemia (OR 19.9, CI 14.5-27.2). CONCLUSION Overall, the risk of transfusion in association with cesarean is low. However, both severe preoperative maternal anemia and placenta previa are associated with markedly increased risks. The former argues for optimizing maternal antenatal iron status to avoid severe anemia and the latter for careful perioperative planning when previa complicates cesarean. LEVEL OF EVIDENCE II-2.

Abstract
BACKGROUND Routine pretransfusion testing for red cell alloantibodies (RBCab) in cesarean patients is standard practice in many obstetric centers. The objective of the present study was to evaluate the usefulness of this test. METHOD A retrospective study was conducted using computerized registers to extract data on blood transfusions and the occurrence of RBCab in cesarean patients. RESULTS A total of 4434 admissions for cesarean section were identified. Only 10 patients (0.23%) had clinically significant RBCab, which had not been previously detected. Blood transfusions were required in relation to 147 cesarean sections (3.3%). A number of preoperative conditions, traditionally believed to be risk factors for preoperative and postpartum hemorrhage, occurred more frequently in transfused patients than in nontransfused. The probability of a cesarean patient having a previously undetected clinically significant RBCab and receiving a blood transfusion during admission for delivery was estimated to be 9.0 x 10(-5) (1 in 11 050 cesarean sections). Analyses of the time relationships between cesarean sections and initiation of blood transfusions indicated that most often there would be enough time for postoperative antibody screening and/or cross matching if the routine pretransfusion testing was omitted. CONCLUSION These findings suggest that routine pretransfusion testing in cesarean patients can be omitted.

Abstract
OBJECTIVE We evaluated the safety of intraoperative autologous blood collection and autotransfusion during cesarean section. STUDY DESIGN A multicenter historical cohort study identified 139 patients in whom autologous blood collection autotransfusion during cesarean section was performed. We also identified 87 control patients who underwent similar surgical procedures at the same centers without autotransfusion. The outcome variables we compared were acute respiratory distress syndrome, amniotic fluid embolism, disseminated intravascular coagulation, need for ventilatory support, infectious morbidity, and the length of postpartum hospitalization. RESULTS Demographic and obstetric characteristics were similar in both groups. The ranges of autotransfused volumes were 200 to 11,250 mL at Yale, 225 to 1160 mL at Good Samaritan, and 125 to 4750 mL at Hinsdale. No statistically significant differences existed between the two groups in any of the outcome variables analyzed. No case of acute respiratory distress syndrome or amniotic fluid embolism was identified in either group. CONCLUSIONS Our multicenter experience reveals no demonstrably increased risk of complications in patients receiving autologous blood collection autotransfusion during cesarean section.

Abstract
The drive to contain the rising cost of medical care provides numerous challenges to blood bankers. Not the least of these is the opportunity to improve quality of care while reducing the cost thereof. This paper explores various cost-reduction strategies, focusing primarily on those applicable to small and medium-sized transfusion services, and demonstrates methods by which they can be implemented to yield improved patient care.
