Abstract
Patient blood management (PBM) strategies aim to maintain hemoglobin concentration, optimize hemostasis, and minimize blood loss to improve patient outcomes. Because postpartum hemorrhage (PPH) is a leading cause of maternal mortality and blood product utilization, PBM principles can be applied in its therapeutic approach. First, pre-operative identification of risk factors for PPH and identification of peri-delivery anemia should be conducted. Iron supplementation should be used to optimize hemoglobin concentration before delivery; it can also be used to treat anemia in the postpartum period after severe PPH. Both acute normovolemic hemodilution and intraoperative cell salvage can be effective techniques to reduce allogeneic blood transfusion during or after surgical procedures. Furthermore, these strategies appear to be safe when used in the pregnant population.

JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2022; 27:63. [PMID: 36353346 PMCID: PMC9639719 DOI: 10.4103/jrms.jrms_763_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 02/28/2022] [Accepted: 03/07/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Placenta adherent abnormality (PAA) is abnormal attachment of the placenta to the myometrium. This abnormal placenta binding has severe clinical consequences for the mother and the fetus. We investigated the outcomes of hypogastric arterial ligation (HAL) before hysterectomy compared to hysterectomy alone in pregnant women with PAA. MATERIALS AND METHODS In this randomized controlled clinical trial, 70 patients were randomly allocated to HAL along with hysterectomy and hysterectomy alone groups (35 in each Group). The total amount of intraoperative blood loss, the need for intraoperative blood products transfusion, frequency of deep vein thrombosis, duration of surgery, duration of hospitalization, and visceral trauma were compared between 2 Groups. RESULTS Finally, 64 patients completed the study protocol with mean age of 33.84 ± 4.25 years. The study groups were comparable in terms of basic baseline demographic and clinical characteristics. Visceral trauma was less frequently occurred in HAL group compared to hysterectomy alone (0% vs. 15.6%; P = 0.02). Intraoperative blood loss (1525 ± 536.41 cc vs. 2075 ± 889.36 cc; P = 0.001) and were significantly lower in HAL group compared to hysterectomy alone. Duration of operation (179.06 ± 36.28 vs. 197.66 ± 39.47; P = 0.05) and hospitalization (4.97 ± 2.20 vs. 6.10 ± 2.39; P = 0.03) also were significantly lower in HAL group. CONCLUSION Our findings suggest that prophylactic HAL has a protective effect on the reduction of blood loss and less visceral trauma in pregnant women with PAA.

Abstract
AIM Intraoperative cell salvage and autotransfusion (ICSA) is a useful technique for women undergoing cesarean sections who are predicted to experience significant bleeding. This method can reduce allogeneic transfusions as well as its associated risks and costs. Amniotic fluid embolism (AFE) is an abnormal maternal response to ICSA similar to the classic systemic inflammatory response syndrome, but its mechanism is not well understood. This study was conducted to investigate the biochemical aspects of AFE. METHODS A prospective case-controlled pilot study was conducted in a general perinatal hospital in Japan. ICSA was performed using a two-step retransfusion process. Blood samples were collected presurgery, immediately postsurgery, and 24 h after surgery. Changes in sialyl Tn antigen (STN), complement C3 and C4, fibrinogen, and fibrin degradation product and D-dimer, C1 esterase inhibitor, and interleukin-8 (all considered AFE-related markers) activities were compared between patients who underwent cesarean sections with ICSA (ICSA group) versus without ICSA (control group). RESULTS Fibrinogen levels were significantly lower in the ICSA group than in the control group before surgery but not immediately after or 24 h after surgery. D-dimer was significantly higher immediately after surgery but not 24 h later. STN was significantly lower only before surgery. None of the AFE-related markers showed significant differences between the groups after 24 h. No adverse events were observed in the ICSA group. CONCLUSIONS There is no clinical evidence that ICSA alters the biochemical statuses of AFE-related markers in a manner that could lead to adverse maternal responses.

Abstract
Background Cell salvage has recently been recommended for obstetric use in cases with a high risk of massive hemorrhage during cesarean section (CS). However, limited data are available to support the use of one suction device to collect lost blood. This study aimed to investigate the volume of red blood cells (RBCs) salvaged and the components of amniotic fluid (AF) in blood salvaged by one suction device or two devices during CS in patients with placenta previa and/or accrete. Methods Thirty patients with placenta previa and/or accrete undergoing elective CS in the Women's Hospital of Zhejiang University School of Medicine were recruited for the present study from November 1, 2017 to December 1, 2018. The patients were randomly assigned to one of the two groups according to an Excel-generated random number sheet: Group 1 (n = 15), in which only one suction device was used to aspirate all blood and AF, and Group 2 (n = 15), in which a second suction device was mainly used to aspirate AF before the delivery of the placenta. Three samples of blood per patient (pre-wash, post-wash, and post-filtration) were collected to measure AF components. The salvaged RBC volumes were recorded. Continuous data of pre-wash, post-wash, and post-filtration samples were analyzed by using one-way analysis of variance with Tukey's test for multiple comparisons, or Kruskal-Wallis test with Dunn test for multiple comparisons. Comparisons of continuous data between Group 1 and Group 2 were conducted using Student's t test or Mann-Whitney U test. Results The salvaged RBC volume was significantly higher in Group 1 than that in Group 2 (401.6 ± 77.2 mL vs. 330.1 ± 53.3 mL, t = 4.175, P < 0.001). In both groups, squamous cells, lamellar bodies, and fat were significantly reduced by washing (all P<0.001) and squamous cells were further reduced by filtering (P < 0.001). Squamous cells were found in six post-filtration samples (three from each group). Lamellar bodies and fat were completely removed by filtering. Insulin-like growth factor binding protein 1, alpha-fetoprotein, albumin, lactate dehydrogenase, and potassium were significantly reduced post-wash (all P < 0.05), with no further significant reduction after filtration in either group (all P > 0.05). The mean percentage of fetal RBCs post-filtration was (1.8 ± 0.8)% with a range of 1.0% to 3.5% and (1.9 ± 0.9)% with a range of 0.7% to 4.0% in Groups 1 and 2, respectively, showing no significant difference between the two groups (U = 188.5, P = 0.651). Conclusion Cell salvage performed by one suction device could result in higher volume of salvaged RBCs and can be used safely for CS in patients with placenta previa and/or accrete when massive hemorrhage occurs.

Abstract
OBJECTIVE To compare surgical outcomes between women undergoing prophylactic internal iliac artery ligation or preoperative placement of balloon-occlusive devices at cesarean hysterectomy for placenta accreta spectrum (PAS) disorders. METHODS A retrospective cohort study was conducted at a tertiary-care referral center for PAS disorders in Ontario, Canada. Eligible electronic records were reviewed of women undergoing cesarean hysterectomy for PAS disorders between November 2012 and June 2018. Outcomes for the ligation and balloon groups were compared primarily on procedure-related complications and secondarily on total procedure time, bleeding and transfusion metrics, and intraoperative and postoperative complications. RESULTS Of the 79 cases of cesarean hysterectomy, 47 underwent balloon placement and 32 underwent ligation. Baseline characteristics between the groups were similar except for more emergency procedures in the ligation group (37.5% vs 12.8%, P=0.014). The balloon-related complication rate was 5/47 (10.6%), with no reported complications in the ligation group (P=0.077). Procedural time was longer in the balloon group (353 ± 14 vs 227 ± 13 minutes, P<0.001). Estimated blood loss was similar (1874 ± 245 mL vs 1713 ± 181 mL, P=0.590). CONCLUSION Women undergoing prophylactic placement of endovascular balloons at caesarean hysterectomy for PAS disorders had a 10.6% procedure-related complication rate and increased total procedure time, with no decrease in blood loss compared to those undergoing surgical ligation.

Intraoperative cell salvage as part of a blood conservation strategy in an obstetric population with abnormal placentation at a large Irish tertiary referral centre: an observational study. Ir J Med Sci 2020; 189:1053-1060.

Abstract
BACKGROUND Haemorrhagic morbidity is more common in women with abnormal placentation, that is placenta praevia or morbidly adherent placenta. The incidence of abnormal placentation is increasing due to rising caesarean section rates. Concerns regarding blood safety, blood shortages and soaring costs of blood processing have generated growing enthusiasm for blood conservation strategies. The aim of our study was to look at intraoperative cell salvage (IOCS) use and allogeneic transfusion patterns in patients with abnormal placentation. METHODS Patients with abnormal placentation were identified from the hospital database over a 2-year period between 2015 and 2016. Information collected for those that had IOCS setup included estimated blood loss, volume of blood collected and returned, pre- and postoperative haemoglobin levels and use of allogeneic blood. RESULTS A total of 139 cases of abnormal placentation were identified. Abnormal placentation accounted for 62% of all cases of IOCS usage and was established for 53 patients with abnormal placentation. The re-transfusion rate was 18.5%. Five patients received IOCS blood only. The allogeneic transfusion rate was 7.5% in patients who had IOCS setup compared with 6.9% in those who did not (p = 1.00). Median blood loss was greater for patients who had IOCS blood returned compared with patients who had not (p = 0.004). The median volume of blood returned was 520 (114-608) mL. Preoperative haemoglobin levels were lower for patients who received a combination of cell salvage and allogeneic blood (p = 0.006). CONCLUSIONS IOCS contributed to a reduction or elimination of allogeneic transfusion for a proportion of this high-risk cohort and should be an integral component of a hospitals' blood conservation strategy.

Abstract
OBJECTIVE To assess the impact of intra-operative cell salvage on outcomes in open nephrectomy. METHODS A retrospective cohort study was performed of all patients undergoing open nephrectomy for suspected malignancy from 1 October 2013 to 1 October 2017. Patients were grouped and compared based on whether they received intra-operative cell salvage (ICS). Primary outcomes were allogeneic transfusion rates (ATRs), and if histology confirmed cancer, disease recurrence. Secondary outcomes were complications and transfusion-related cost. RESULTS Forty patients underwent open nephrectomy for suspected malignancy during the enrolment period. Sixteen patients received ICS while 24 did not (standard group). Compared with the standard group, ICS patients had similar median age (63.5 vs. 61.0 years; p = 0.83) but fewer females (19% vs. 58%; p = 0.013). The groups were similar in pre-operative and discharge haemoglobin, Charlson Comorbidity Index, length of hospital stay and proportion with thoracoabdominal surgical approach. The ICS group had a smaller proportion undergoing partial nephrectomy (19% vs. 54%; p = 0.025) and shorter median follow-up (278 vs. 827 days; p = 0.0005). Histology was malignant for 14 ICS and 15 standard patients. The ICS group had more frequent ≥T2 disease (79% vs. 27%; p = 0.005). There were no positive margins. Both groups had similar ATRs (6% vs. 4%; p = 0.96), complication rates (19% vs. 29%; p = 0.46) and recurrence rates (18% vs. 7%; p = 0.40). Transfusion costs were higher amongst ICS patients (AUD $878.18 vs. $49.65 per patient). CONCLUSION ICS appears safe, with low rates of recurrence and complication. Both groups had low ATRs, and therefore cost benefit for ICS was not seen.

Abstract
Background To examine the effect of intra-operative cell salvage (ICS) in open radical prostatectomy. Methods In this retrospective cohort study, all patients undergoing open radical prostatectomy for malignancy at our institution between 10/04/2013 and 10/04/2017 were enrolled. Patients were grouped and compared based on whether they received ICS. Primary outcomes were allogeneic transfusion rates, and disease recurrence. Secondary outcomes were complications and transfusion-related cost. Results Fifty-nine men were enrolled; 30 used no blood conservation technique, while 29 employed ICS. There were no significant differences between groups in age, pre- or post-operative haemoglobin, Charlson comorbidity index, operation duration or length of stay. Tumour characteristics were also similar between groups, including pre-operative prostate specific antigen, post-operative Gleason score, T-stage, nodal status and rates of margin positivity. Compared with controls, the ICS group had longer follow up (945 vs. 989 days; P=0.0016). The control and ICS groups were not significantly different in rates of tumour recurrence (6 vs. 3 patients; P=0.30) or complications (10 vs. 5 patients; P=0.16). While the proportion of patients receiving allogenic transfusion was similar (9 vs. 6 patients; P=0.41), fewer red blood products transfused (40 vs. 12 units) meant transfusion related costs were lower in ICS patients (AUD $47,666 vs. $37,429). Conclusions ICS reduced transfusion related costs, without affecting allogeneic transfusion rates, tumour recurrence or complication rates. These findings extend the literature supporting ICS in oncological surgery. Prospective randomised studies are needed to confirm the existing level III evidence.

Abstract
BACKGROUND The significance of fetal red blood cell (RBC) contamination in obstetric intra-operative cell salvage is not fully known. It is unclear if we re-infuse a larger volume of fetal RBCs into the maternal circulation than the amount that occurs secondary to transplacental haemorrhages is unclear. We also do not know if there is a critical volume required to cause alloimmunisation or if larger volumes increase the risk. OBJECTIVES The aim of this study is to provide data on the level of fetal RBC contamination in the maternal circulation prior to delivery and immediately post-partum and to compare these levels to those found in processed cell-salvaged blood. METHODS In the first part of this study, we quantified the levels of fetal RBCs circulating in women immediately prior to delivery. This was then repeated with a separate group measuring the levels of fetal RBCs pre- and post-delivery. RESULTS We found that 37% of women had fetal cells detected in their circulation, median 0·00 mL (IQR 0-0·24; average 0·3 mL, maximum 4·56 mL). Fetal RBCs were present pre-delivery (maximum 0·66 mL) in 16% of women, increasing to 53% post-delivery (median 0·66 mL; IQR 0·22-2·20, maximum 21·20 mL). CONCLUSIONS We have shown that fetal RBCs are present in the maternal circulation throughout pregnancy and that the volumes are comparable to that obtained from intra-operative salvage, with contamination amounts of up to 19 mL. At the Royal Cornwall Hospital, our experience and evidence supports offering intra-operative salvage to all women, and we have not noted an increase in antibody formation, compared to allogeneic transfusion.

Abstract
INTRODUCTION Intraoperative cell salvage (ICS) is an important aspect of patient blood management programmes. An ICS service was introduced at KK Women's and Children's Hospital, Singapore, from 2 May 2011 to 30 April 2013 to aid in the management of massive obstetric haemorrhage. METHODS With support from the Ministry of Health's Healthcare Quality Improvement and Innovation Fund, a workgroup comprising obstetricians, anaesthetists and nursing staff was formed to develop training requirements, clinical guidelines and protocols for implementing ICS using the Haemonetics Cell Saver 5. Pregnant women with an anticipated blood loss of > 1,000 mL during Caesarean delivery, a baseline haemoglobin level of < 10 g/dL, rare blood types and who had refused donor blood were recruited to the service after obtaining informed consent. RESULTS A total of 11 women were recruited to the ICS service; the primary indications were placenta praevia and placenta accreta. Median blood loss in these 11 patients was 1,500 (range 400-3,000) mL. In four patients, adequate autologous blood was collected to initiate processing and salvaged, processed blood was successfully reinfused (mean 381.3 [range 223.0-700.0] mL). Median blood loss among these four patients was 2,000 (range 2,000-3,000) mL. No adverse event occurred following autologous transfusion. Mean immediate postoperative haemoglobin level was 8.0 (range 7.1-9.4) g/dL. CONCLUSION The implementation of an obstetric ICS service in our institution was successful. Future studies should seek to address the cost-effectiveness of ICS in reducing allogeneic blood utilisation.

Abstract
OBJECTIVE To use decision analysis to evaluate whether and under what conditions routine setup of intraoperative cell salvage during cesarean delivery is cost-saving. METHODS We developed a decision model to compare costs associated with two strategies for cesarean delivery: 1) routine setup of intraoperative cell salvage; or 2) standard care without intraoperative cell salvage. One-, two-, and three-way sensitivity analyses as well as Monte Carlo simulation were used to assess the robustness of our findings. RESULTS Among nonselected women undergoing cesarean delivery, our base case estimate was that 3.2% would require red blood cell transfusion. Under this assumption, cell salvage is cost-saving only if each woman requires at least 60 units. Conversely, if only two units on average are required, the probability of transfusion needs to be at least 58% for cell salvage to be cost-saving. In our base case analysis, setup of intraoperative cell salvage during routine cesarean deliveries is not cost-saving, increasing the cost per cesarean delivery by $223.80. We found that cell salvage would be cost-saving only in very high-risk scenarios. For example, severe maternal anemia or abnormal placentation, in which 54% and 75% of women are transfused three and two units per case, respectively, would make cell salvage cost-saving. CONCLUSION Setup of intraoperative cell salvage during cesarean delivery is cost-saving and should be considered only when there is a predictably high probability of transfusion or when a massive transfusion is reasonably likely.

Abstract
Intra-operative blood salvage is common practice in many surgical specialties but its safety is questioned with concerns about the risks of contamination of recovered blood with amniotic fluid and of maternal-foetal alloimmunization. However, the role of cell salvage as a blood-saving measure in this clinical setting is progressively acquiring relevance thanks to the growing body of evidence regarding its quality and safety. Modern cell savers remove most particulate contaminants and leukodepletion filtering of salvaged blood prior to transfusion adds further safety to this technique. Amniotic fluid embolism is no longer regarded as an embolic disease and the contamination of the salvaged blood by foetal Rh-mismatched red blood cells can be dealt with using anti-D immunoglobulin; ABO incompatibility tends to be a minor problem since ABO antigens are not fully developed at birth. Maternal alloimmunization can be caused also by other foetal red cell antigens, but it should also be noted that the risk of alloimmunization of the mother from allogeneic transfusion may be even greater. Therefore the use of cell savers in obstetric clinical practice should be considered in patients at high risk for haemorrhage or in cases where allogeneic blood transfusion is difficult or impossible.
