Perioperative Blood Transfusion

Open radical cystectomy is associated with a substantial rate of perioperative blood transfusion. Early detection of potentially modifiable perioperative factors could reduce the need for perioperative blood transfusion and thus positively impact the outcome. We conducted an observational, single-center cohort study of 1168 patients undergoing cystectomy. Perioperative blood transfusion was defined as the need for packed red blood cells and/or fresh frozen plasma units within the first 24 h after the initiation of surgery. Multiple logistic regression analysis was performed to model the association between risk factors and blood transfusion, and a nomogram was developed. Blood transfusion occurred in 370/1168 patients (31.7%). Significant predictors were age (OR: 1.678, (95% CI: 1.379–2.042); p < 0.001), blood loss ratio (6.572, (4.878–8.853); p < 0.001), preoperative hemoglobin (0.316, (0.255–0.391); p < 0.001), tumor stage (2.067, (1.317–3.244); p = 0.002), use of oral anticoagulants (2.70, (1.163–6.270), p = 0.021), and interaction between female sex and blood loss ratio (1.344, (1.011–1.787); p = 0.042). Of the major predictors found to affect perioperative blood transfusion, two can be influenced: blood loss ratio by meticulous surgery and hemoglobin by preoperative optimization. Others such as age or advanced disease are not modifiable. This emphasizes the importance of optimal management of patients prior to surgery.

AbstractTo evaluate potential factors associated with the risk of perioperative blood transfusion (PBT) with implications on length of hospital stay (LOHS) and major post-operative complications in patients who underwent robot-assisted radical prostatectomy (RARP) as a primary treatment for prostate cancer (PCa). In a period ranging from January 2013 to August 2019, 980 consecutive patients who underwent RARP were retrospectively evaluated. Clinical factors such as intraoperative blood loss were evaluated. The association of factors with the risk of PBT was investigated by statistical methods. Overall, PBT was necessary in 39 patients (4%) in whom four were intraoperatively. Positive surgical margins, operating time and intraoperative blood loss were associated with perioperative blood transfusion on univariate analysis. On multivariate analysis, the risk of PBT was predicted by intraoperative blood loss (odds ratio, OR 1.002; 95% CI 1.001–1.002; p < 0.0001), which was associated with prolonged operating time and elevated body mass index (BMI). PBT was associated with delayed LOHS and Clavien–Dindo complications > 2. In patients undergoing RARP as a primary treatment for PCa, the risk of PBT represented a rare event that was predicted by severe intraoperative bleeding, which was associated with increased BMI as well as with prolonged operating time. In patients who received a PBT, prolonged LOHS as well as an elevated risk of major Clavien–Dindo complications were seen.

Abstract Background The incidence of placenta preiva is rising. Cesarean delivery is identified as the only safe and appropriate mode of delivery for pregnancies with placenta previa. Anesthesia is important during the cesarean delivery. The aim of this study is to assess maternal and neonatal outcomes of patients with placenta previa managed with neuraxial anesthesia as compared to those who underwent general anesthesia during cesarean delivery. Methods A retrospective cohort study was performed of all patients with placenta preiva at our large academic institution from January 1, 2014 to June 30, 2019. Patients were managed neuraxial anesthesia and general anesthesia during cesarean delivery. Results We identified 1234 patients with placenta previa who underwent cesarean delivery at our institution. Neuraxial anesthesia was performed in 737 (59.7%), and general anesthesia was completed in 497 (40.3%) patients. The mean estimated blood loss at neuraxial anesthesia of 558.96 ± 42.77 ml were significantly lower than the estimated blood loss at general anesthesia of 1952.51 ± 180 ml (p < 0.001). One hundred and forty-six of 737 (19.8%) patients required blood transfusion at neuraxial anesthesia, whereas 381 out of 497 (76.7%) patients required blood transfusion at general anesthesia. The rate neonatal asphyxia and admission to NICU at neuraxial anesthesia was significantly lower than general anesthesia (2.7% vs. 19.5 and 18.2% vs. 44.1%, respectively). After adjusting confounding factors, blood loss was less, Apgar score at 1- and 5-min were higher, and the rate of blood transfusion, neonatal asphyxia, and admission to NICU were lower in the neuraxial group. Conclusions Our data demonstrated that neuraxial anesthesia is associated with better maternal and neonatal outcomes during cesarean delivery in women with placenta previa.

Drugs that interfere with clotting are discussed. Bleeding, coagulation, and platelet disorders are covered as well as disseminated intravascular coagulation. Part two is concerned with bleeding in the recovery room: how to cope with rapid blood loss, managing ongoing blood loss, and how to use clotting profiles to guide treatment. There is also a section covering blood transfusion, blood groups and typing. Massive blood transfusion is clearly described, there are guidelines about when to use fresh frozen plasma, when to use platelets, and when to use cryoprecipitate. The final section of the chapter is about problems with blood transfusions.

Perioperative Blood Transfusion

To analyze the dynamic variation in perioperative hidden blood loss in patients with intertrochanteric fracture. From January to December 2017, 79 patients with intertrochanteric fracture were treated with proximal femoral nail antirotation. Serial complete blood count assays were performed consecutively in the 3 days after admission, on the day of surgery, and 7 days postoperatively. Blood loss during surgery, postoperative drainage, and perioperative blood transfusion volumes were recorded. Dynamic changes in hemoglobin (Hb) prior to surgery were recorded and compared between males and females. Patients were divided into the no blood transfusion group, the 400-mL blood transfusion group, and the 800-mL blood transfusion group depending on the volume of perioperative blood transfusion. Total and hidden blood loss were separately calculated according to the Gross equation. Lowest mean Hb values occurred on day 2 after admission among men (104.8 g/L) and on day 3 after admission among women (98.6 g/L). The average Hb decrease was 11.4 g/L, 11.8 g/L, and 8.9 g/L in the no, 400-mL, and 800-mL blood transfusion groups, respectively. The lowest Hb value occurred on postoperative day 2. Hemoglobin increased on postoperative day 3 and stabilized by day 6. In the no blood transfusion group, the average total blood loss was 406.0 ± 255.6 mL, 628.3 ± 267.2 mL, and 759.7 ± 322.1 mL in the no blood transfusion, 400-mL blood transfusion, and 800-mL blood transfusion groups, respectively, and hidden blood loss was 326.0 ± 246.6 mL, 512.1 ± 247.3 mL, and 596.1 ± 306.9 mL, respectively. Perioperative hidden blood loss occurred prior to surgery for intertrochanteric fracture and ended on postoperative day 2.

Background: Appropriate blood component transfusion might differ between intraoperative massive bleeding and traumatic massive bleeding in the emergency department because trauma patients initially bleed undiluted blood and replacement typically lags behind blood loss. We compared these two blood loss scenarios, intraoperative and traumatic, using a computer simulation.Methods: We modified the multi-compartment dynamic model developed by Hirshberg and implemented it using STELLA 9.0. In this model, blood pressure changes as blood volume fluctuates as bleeding rate and transcapillary refill rate are controlled by blood pressure. Using this simulation, we compared the intraoperative bleeding scenario with the traumatic bleeding scenario. In both scenarios, patients started to bleed at a rate of 50 ml/min. In the intraoperative bleeding scenario, fluid was administered to maintain isovolemic status; however, in the traumatic bleeding scenario, no fluid was supplied for up to 30 min and no blood was supplied for up to 50 min. Each unit of packed red blood cells (PRBC) was given when the hematocrit decreased to 27%, fresh frozen plasma (FFP) was transfused when plasma was diluted to 30%, and platelet concentrate (PC) was transfused when platelet count became 50,000/ml.Results: In both scenarios, the appropriate ratio of PRBC:FFP was 1:0.47 before PC transfusion, and the ratio of PRBC:FFP:platelets was 1:0.35:0.39 after initiation of PC transfusion.Conclusion: The ratio of transfused blood component did not differ between the intraoperative bleeding and traumatic bleeding scenarios.
