Abstract
PURPOSE Transfusing red blood cells promptly corrects anemia and improves tissue oxygenation in around 40% of patients hospitalized in the intensive care unit (ICU) after major surgical operations. This study's goal is to investigate how blood transfusions affect the mortality rates of patients after major surgery who are hospitalized in the ICU. METHODS Retrospective research was done on recently hospitalized patients who had major procedures in the ICU between October 2020 and February 2022 at the Huanggang Central Hospital of Yangtze University, China. The patients' prognoses at three months were used to classify them as either survivors or deceased. Patient demographic information, laboratory results, and blood transfusion histories were acquired, and the outcomes of the two groups were compared based on the differences. Univariate and multivariate logistic regression analyses were used to examine the prognosis of surgical disease patients first admitted to the ICU. The receiver operating characteristic (ROC) curve was used to evaluate the predictive power of each risk factor. The relationship between transfusion frequency, transfusion modality, and patient outcome was examined using Spearman's correlation analysis. RESULTS Data from 384 patients was included in the research; of them, 214 (or 55.7%) died within three months of their first stay in the ICU. The death group had higher scores on the Acute Physiology and Chronic Health Evaluation II (APACHE II) and the Sequential Organ Failure Assessment (SOFA) than the survival group did (all P < 0.05); the death group also had lower scores on the Glasgow Coma Scale, systolic blood pressure, hemoglobin, platelet distribution width, and blood transfusion ratio. Multivariate logistic regression analysis revealed an odds ratio (OR) of 1.654 (1.281-1.989), a 95% confidence interval (CI) of 1.440 (1.207-1.701), and a P value of 0.05 for death in patients undergoing major surgery who were hospitalized to the intensive care unit (ICU). Areas under the ROC curve (AUC) of 0.836, 0.799, and 0.871, respectively, and 95% CIs of 0.796-0.875, 0.755-0.842, and 0.837-0.904, respectively, all P0.05, had significant predictive value for patients initially admitted to the ICU and for APACHE II score > = 12 points, SOFA score > = 6, and blood transfusion. When all three indicators were used jointly to predict a patient's prognosis after major surgery, the accuracy increased to 86.4% (sensitivity) and 100% (specificity). There was a negative correlation between the number of blood transfusions a patient had and their outcome (r = 0.605, P < 0.001) and death (r = 0.698, P < 0.001). CONCLUSION A higher initial ICU APACHE II score, SOFA score, and a number of blood transfusions were associated with improved survival for patients undergoing major surgical operations. Patients' death rates have increased with the increase in the frequency and variety of blood transfusions.

Vox Sang 2022; 117:1384-1390. [PMID: 36300858 PMCID: PMC9772120 DOI: 10.1111/vox.13372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 09/27/2022] [Accepted: 10/08/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND AND OBJECTIVES The management of intraoperative blood loss in the surgical treatment of paediatric hip dysplasia is resource intensive. There are numerous clinical factors that impact the need for intraoperative transfusion. Identification of patient and surgical factors associated with increased blood loss may reduce the unnecessary use of resources. This study aimed to identify factors predictive of intraoperative transfusion in children undergoing hip dysplasia surgery. MATERIALS AND METHODS This is a single-centre retrospective review of patients undergoing surgery for hip dysplasia from 1 January 2012 to 15 April 2021. Patient demographic factors, anaesthetic, surgical and transfusion histories were reviewed. Multivariable logistic regression analysis was performed to identify factors predictive of allogeneic red blood cell transfusion requirements during the intraoperative period. RESULTS This study includes 595 patients who underwent open surgery for hip dysplasia, including 297 (52.6%) classified as developmental dysplasia (DD) and 268 (47.3%) as neuromuscular (NM) with a mean age of 9.1 years (interquartile range 3-14). Intraoperative allogeneic transfusion was identified in 26/297 (8.8%) DD and 73/268 (27.2%) NM patients. Adjusted factors associated with increased odds of intraoperative transfusion were NM (odds ratio [OR] = 2.96, 95% confidence interval [CI] [1.76, 5.00]) and the number of osteotomies performed (OR = 1.82/osteotomy, 95% CI [1.40, 2.35]). Adjusted factors that reduced the odds of transfusion were the use of antifibrinolytics (OR = 0.35, 95% CI [0.17, 0.71]) and regional anaesthesia (OR = 0.52, 95% CI [0.29, 0.94]). CONCLUSION For children undergoing surgery for hip dysplasia, the number of osteotomies performed is predictive of the need for allogeneic blood transfusion. Antifibrinolytics and regional anaesthesia are associated with reduced risk for allogeneic blood transfusion. Blood management initiatives, such a preoperative optimization of haemoglobin and the use of antifibrinolytics, could target patients at increased risk of intraoperative bleeding and transfusion.

No impact of sex on surgical site infections in abdominal surgery: a multi-center study. Langenbecks Arch Surg 2022; 407:3763-3769. [PMID: 36214869 DOI: 10.1007/s00423-022-02691-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Accepted: 09/15/2022] [Indexed: 10/17/2022]
Abstract
OBJECTIVE Male sex is controversially discussed as a risk factor for surgical site infections (SSI). The aim of the present study was to evaluate the impact of sex on SSI in abdominal surgery under elimination of relevant confounders. METHODS Clinicopathological data of 6603 patients undergoing abdominal surgery from a multi-center prospective database of four Swiss hospitals including patients between 2015 and 2018 were assessed. Patients were stratified according to postoperative SSI and risk factors for SSI were identified using univariate and multivariate analysis. RESULTS In 649 of 6603 patients, SSI was reported (9.8%). SSI was significantly associated with reoperation (22.7% vs. 3.4%, p < 0.001), increased mortality rate (4.6% vs. 0.9%, p < 0.001), and increased rate of length of hospital stay > 75th percentile (57.0% vs. 17.9%, p < 0.001). In univariate analysis, male sex was a significant risk factor for SSI (p = 0.01). In multivariate analysis including multiple confounders' such as comorbidities and perioperative factors, there was no association between male sex and risk of SSI (odds ratio (OR) 1.1 [CI 0.8-1.4]). Independent risk factors for SSI in multivariate analysis were BMI ≥ 30 kg/m2 (OR 1.8 [CI 1.3-2.3]), duration of surgery > 75th percentile (OR 2.3 [1.8-2.9]), high contamination level (OR 1.3 [1.0-1.6]), laparotomy (OR 1.3 [1.0-1.7]), previous laparotomy (OR 1.4 [1.1-1.7]), blood transfusion (OR 1.7 [1.2-2.4]), cancer (OR 1.3 [1.0-1.8] and malnutrition (OR 2.5 [1.8-3.4]). CONCLUSION Under elimination of relevant confounders, there is no significant correlation between sex and risk of SSI after abdominal surgery.

Abstract
OBJECTIVE To investigate the influence of prestorage leukoreduction of packed RBCs (pRBCs) on acute transfusion-related complication rate in dogs. SETTING Two private referral hospitals. DESIGN Retrospective case study. ANIMALS Four hundred and fifty-five dogs receiving nonleukoreduced (nLR) or leukoreduced (LR) pRBC between January 1, 2014 and July 31, 2017. MEASUREMENTS AND MAIN RESULTS Transfusions were retrospectively reviewed to record data about the patient, donor, unit, transfusion event, acute complications, hospital discharge, and cause of death. Of 730 transfusion events in 455 dogs, 288 used LR pRBC and 442 used nLR pRBC. There was a 18.9% (138/730) overall complication rate. Seven (0.96%) complications were life-threatening. The most common complications were pyrexia (5.6%), gastrointestinal signs (4.9%), and hemolysis with no other signs (4.1%). Pyrexia with no other clinical signs, consistent with a febrile nonhemolytic transfusion reaction (FNHTR), occurred in 3.2% of transfusion events. There was a significant (P = 0.03) decrease in the rate of FNHTR with LR pRBC (1%) versus nLR pRBC (4.5%). Use of LR pRBC did not decrease in-hospital mortality. The odds of any complication, hemolysis only, FNHTR, and more severe complications increased with pRBC age. Leukoreduction did not decrease the impact of pRBC age on these complications. Use of older pRBC did not increase the incidence of life-threatening complications or mortality. Dogs receiving pRBC for blood loss were more likely to have gastrointestinal and more severe complications than those dogs that had hemolysis. The effect of pRBC unit age on complications was not influenced by the underlying reason for transfusion. Dogs that received a previous transfusion were more likely to have respiratory complications. CONCLUSION In this study, the use of LR pRBC was associated with a decreased rate of FNHTR but no other complications. Unit age was associated with the incidence of hemolysis, FNHTR, and complication severity but not the rate of life-threatening complications or mortality.

Abstract
BACKGROUND Allogeneic red blood cell (RBC) transfusion can induce immunosuppression, which can then increase the susceptibility to postoperative infection. However, studies in different types of surgery show conflicting results regarding this effect. METHODS In this retrospective cohort study conducted in a tertiary referral centre, we included adult patients undergoing clean-contaminated surgery from 2014 to 2018. Patients who received allogeneic RBC transfusion from preoperative Day 30 to postoperative Day 30 were included into the transfusion group. The control group was matched for the type of surgery in a 1:1 ratio. The primary outcome was infection within 30 days after surgery, which was defined by healthcare-associated infection, and identified mainly based on antibiotic regimens, microbiology tests, and medical notes. RESULTS Among the 8098 included patients, 1525 (18.8%) developed 1904 episodes of postoperative infection. Perioperative RBC transfusion was associated with an increased risk of postoperative infection after controlling for 27 confounders by multivariable regression analysis (odds ratio [OR]: 1.60; 95% confidence interval [CI]: 1.39-1.84; P<0.001) and propensity score weighing (OR: 1.64; 95% CI: 1.45-1.85; P<0.001) and matching (OR: 1.70; 95% CI: 1.43-2.01; P<0.001), and a dose-response relationship was observed. The transfusion group also showed higher risks of surgical site infection, pneumonia, bloodstream infection, multiple infections, intensive care admission, unplanned reoperation, prolonged postoperative length of hospital stay, and all-cause death. CONCLUSIONS Perioperative allogeneic RBC transfusion is associated with an increased risk of infection after clean-contaminated surgery in a dose-response manner. Close monitoring of infections and enhanced prophylactic strategies should be considered after transfusion.

Abstract
BACKGROUND Flow cytometry (FCM) is a rapid diagnostic tool for monitoring immune cell function. We sought to determine if assessment of cell phenotypes using standardized FCM could be used to identify nosocomial infection after trauma. METHODS Prospective study of trauma patients at a Level I center from 2014 to 2018. Clinical and FCM data were collected within 24 hours of admission. Random forest (RF) models were developed to estimate the risk of severe sepsis (SS), organ space infection (OSI), and ventilator-associated pneumonia (VAP). Variables were selected using backward elimination and models were validated with leave-one-out. RESULTS One hundred and thirty-eight patients were included (median age, 30 years [23-44 years]; median Injury Severity Score, 20 (14-29); 76% (105/138) Black; 60% (83/138) gunshots). The incidence of SS was 8.7% (12/138), OSI 16.7% (23/138), and VAP 18% (25/138). The final RF SS model resulted in five variables (RBCs transfused in first 24 hours; absolute counts of CD56- CD16+ lymphocytes, CD4+ T cells, and CD56 bright natural killer [NK] cells; percentage of CD16+ CD56+ NK cells) that identified SS with an AUC of 0.89, sensitivity of 0.98, and specificity of 0.78. The final RF OSI model resulted in four variables (RBC in first 24 hours, shock index, absolute CD16+ CD56+ NK cell counts, percentage of CD56 bright NK cells) that identified OSI with an AUC of 0.76, sensitivity of 0.68, and specificity of 0.82. The RF VAP model resulted in six variables (Sequential [Sepsis-related] Organ Failure Assessment score: Injury Severity Score; CD4- CD8- T cell counts; percentages of CD16- CD56- NK cells, CD16- CD56+ NK cells, and CD19+ B lymphocytes) that identified VAP with AUC of 0.86, sensitivity of 0.86, and specificity of 0.83. CONCLUSIONS Combined clinical and FCM data can assist with early identification of posttraumatic infections. The presence of NK cells supports the innate immune response that occurs during acute inflammation. Further research is needed to determine the functional role of these innate cell phenotypes and their value in predictive models immediately after injury. LEVEL OF EVIDENCE Prognostic, level III.

Abstract
Abstract
Objective Despite being the most common postoperative complication and having associated morbidity and mortality that increase health care costs, surgical site infection (SSI) has not received adequate attention and deserves further study. Previous reports in children were limited to SSI in certain populations. We conducted this retrospective case–control study to determine the incidence and possible risk factors for SSI following pediatric general surgical procedures.
Methods This was a retrospective case–control matched cohort study of all patients aged 0 to 14 years who underwent pediatric general surgical procedures between June 2015 and July 2018. The electronic medical records were searched for a diagnosis of SSI. Control subjects were randomly selected at a 4:1 ratio from patients who underwent identical procedures. Multiple risk factors were evaluated by bivariate analysis and multivariable conditional logistic regression.
Results A total of 1,520 patients underwent a general pediatric procedure during the study period, and of these, 47 (3.09%) developed SSIs. A bivariate analysis showed that patients with SSIs were younger, were admitted to the neonatal intensive care unit/pediatric intensive care unit (NICU/PICU) preoperatively, were more severely ill as measured by the ASA classification, underwent multiple procedures, had more surgical complications, and were transferred to the NICU/PICU postoperatively. A multivariate analysis identified four independent predictors of SSI: age, preoperative NICU/PICU admission, number of procedures, and ASA classification.
Conclusion Younger children with preoperative admission to the NICU/PICU, those who underwent multiple procedures and those who were severely ill as measured by their ASA classification were significantly more likely to develop SSIs.

Abstract
BACKGROUND Peri-operative blood transfusion (BT) may lead to transfusion-induced immunomodulation. We aimed to investigate the association between peri-operative BT and infectious complications in patients undergoing intestinal-cutaneous fistulas (ICF) repair. METHODS We queried the ACS-NSQIP 2006-2017 database to include patients who underwent ICF repair. The main outcome was 30-day infectious complications. Univariate and multivariable logistic regression analyses were performed to assess the predictors of post-operative infections. RESULTS Of 4,197 patients included, 846 (20.2%) received peri-operative BT. Transfused patients were generally older, sicker and had higher ASA (III-V). After adjusting for relevant covariates, patients who received intra and/or post-operative (and not pre-operative) BT had higher odds of infectious complications compared (OR = 1.22, 95% CI 1.01-1.48). Specifically, they had higher odds of organ-space surgical site infection (OR = 1.61, 95% CI 1.21-2.13), but not other infectious complications. CONCLUSIONS Intra and/or post-operative (and not pre-operative) BT is an independent predictor of infectious complications in ICF repair.

Abstract
BACKGROUND Heparin is used for anticoagulation during cardiopulmonary bypass. After weaning from bypass, protamine is administered to neutralize the effects of heparin and thus reestablish hemostasis. Rotational thrombelastometry has been shown to discriminate between heparin and other impairing effects on coagulation. We analyzed the interaction of heparin and protamine under different conditions of overdosage in an in-vitro trial. METHODS Blood samples were taken from 17 healthy volunteers, separated, and spiked in vitro with heparin, protamine for heparin neutralization, an overdosage of protamine, and two dosages of re-heparinization to evaluate heparin effects under the condition of protamine overdosage. All samples were analyzed in a standard ROTEM rotational thromboelastometry device after intrinsic activation with and without addition of heparinase. Coagulation time, maximum clot firmness, and clot formation time were recorded. RESULTS Heparin led to prolongation of coagulation and clot formation times in the test without heparinase. Adequate protamine addition normalized the test, and overdosage of protamine led to significant prolongation of both times. Addition of heparin in the presence of protamine overdosage normalized these parameters. CONCLUSION We reconfirmed that the ROTEM device enables discrimination of the effects heparin and protamine on coagulation and detection of the coagulation-impairing effects of protamine overdosage. Furthermore, we were able to show a positive effect on coagulation times by heparin in the presence of protamine overdosage. Because this was an in-vitro study, these findings need to be confirmed in vivo, requiring further research.

Abstract
INTRODUCTION The optimal method of esophageal replacement remains controversial. The aim of this study was to evaluate 30-d outcomes of children in the National Surgical Quality Improvement Project Pediatric (NSQIP-P) database who underwent esophageal replacement from 2012 to 2018. METHODS Demographics, comorbidities, and procedural technique was identified in NSQIP-P and reviewed. Thirty-day outcomes were assessed and stratified by gastric pull-up or tube interposition versus small bowel or colonic interposition. Categorical and continuous variables were assessed by Pearson's chi-square, Fisher's exact, and Wilcoxon rank-sum tests, respectively. Multivariate logistic regression was performed to estimate the effects of procedure technique and clinical risk factors on patient outcomes. RESULTS Of the 99 cases of esophageal replacement included, 52 (52.5%) utilized a gastric conduit, whereas 47 (47.5%) involved small bowel/colonic esophageal interposition. Overall risk of complications was 52.5%, the most common of which were perioperative transfusion (30.3%), surgical site infection (11.1%), and sepsis (9.1%). Risk of unplanned reoperation was 17.2%, and risk of mortality was 3.0%. Risk for complications, reoperation, and readmission did not differ significantly between those who underwent gastric esophageal replacement and those who underwent small bowel or colonic interposition. Median operative time was shorter in the gastric esophageal replacement group (5.2 versus 8.1 h, P = 0.009). CONCLUSIONS Among children in NSQIP-P who underwent esophageal replacement from 2012 to 2018, the risk of 30-d complications, unplanned reoperation, and mortality was relatively frequent and was similar across operative techniques. Opportunities exist to improve preoperative optimization, utilization of blood transfusion services, and infectious complications in the perioperative period irrespective of operative technique. LEVEL OF EVIDENCE Level III, retrospective comparative study.

J Pediatr Surg 2019; 54:2075-2079. [PMID: 30853249 DOI: 10.1016/j.jpedsurg.2019.01.059] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Revised: 01/06/2019] [Accepted: 01/19/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Although preoperative anemia has been suggested to predict postsurgical morbidity and mortality among infants <1 year of age, the data were drawn from heterogeneous patient cohorts including severely ill infants undergoing complex, high-risk procedures. We aimed to determine whether untreated preoperative anemia was associated with increased risk of postoperative complications in infants <1 year of age who underwent pyloromyotomy, a common and relatively simple surgery. METHODS Infants <1 year of age undergoing pyloromyotomy were identified from the American College of Surgeons (ACS) National Surgical Quality Improvement Program-Pediatric database. Preoperative anemia was defined as a hematocrit ≤40% for infants 0-30 days of age and ≤30% for infants more than 30 days of age. Patients who received pre- or postoperative blood transfusions were excluded. RESULTS We identified 2948 patients who met our inclusion criteria, of whom 843 were anemic (29%). The overall rate of complications in this cohort was 6%. The most common postoperative complications were readmission (97 cases), surgical site infection (43), reoperation (39), prolonged hospital stay (24), urinary tract infection (3), 30-day mortality (3) and cardiac arrest (2). We found no differences in the incidence of complications in anemic versus nonanemic patients on bivariate analysis or multivariable logistic regression (adjusted odds ratio = 1.2; 95% confidence interval: 0.8-1.7; P = 0.319). CONCLUSIONS In relatively healthy infants undergoing pyloromyotomy, untreated preoperative anemia was not associated with postoperative compilations and should not be considered a significant risk factor.
