Abstract
STUDY DESIGN Retrospective case control study. OBJECTIVES To determine the role of TXA when used as topical soaked sponges (tTXA) on peri-operative blood loss and changes in hemoglobin following posterior spinal fusion (PSF) for neuromuscular and syndromic scoliosis (NMS). METHODS A single center review of NMS patients who underwent PSF was conducted. The initial set of patients where no tTXA (control) was used were compared to consecutive NMS patients in whom tTXA was used. In the tTXA group, sponges soaked in 1g TXA in 500 mL normal saline were packed in the wound instead of dry sponges. Estimated blood loss (EBL) was calculated intraoperatively using a standard way. Pre-operative, intra-operative and immediate post-operative variables were collected and compared between the 2 groups. RESULTS 33 patients were included (mean age- 13.5 yrs., BMI- 21, 17 patients in tTXA and 16 patients in control group). Pre-op demographic and radiographic variables were similar between the 2 groups. EBL, EBL per level, EBVL, operative time and number of levels fused were similar in both groups. tTXA group received less intra-operative pRBC transfusion as compared to the control group (150 ± 214 vs 363 ± 186 cc, P = .004). No difference was noted in post-op blood transfusion and drain output for 3 days in both the groups. tTXA group had lesser hospital (5.1 vs 8.9 days) and ICU length of stay (2 vs 4.2 days) and fewer immediate post-operative complications (23.5 vs 52.9%) compared to the control group but not statistically significant (P > .05). CONCLUSION Administration of tTXA-soaked sponges is an effective and safe method to reduce intraoperative blood transfusion requirements in the correction of spinal deformity in patients with NMS.

Abstract
BACKGROUND Total hip arthroplasty is a common orthopedic surgery for treating primary or secondary hip osteoarthritis. Bilateral total hip replacement could be performed in a single stage or two separate stages. Each surgical procedure's reliability, safety, and complications have been reported controversially. This study aimed to review the current evidence regarding the outcomes of simultaneous and staged bilateral total hip arthroplasty. METHODS We conducted a meta-analysis using MEDLINE, EMBASE, Web of Science, and Scopus databases. Eligible studies compared complications and related outcomes between simultaneous and staged bilateral THA. Two reviewers independently screened initial search results, assessed methodological quality, and extracted data. We used the Mantel-Haenszel method to perform the meta-analysis. RESULTS In our study, we included 29,551 patients undergoing simBTHA and 74,600 patients undergoing stgBTHA. In favor of the simBTHA, a significant reduction in deep vein thrombosis (DVT) and systemic, local, and pulmonary complications was documented. However, we evidenced an increased pulmonary embolism (PE) and periprosthetic fracture risk in simBTHA. In the simBTHA, total blood loss, length of hospital stay, and total cost were lower. CONCLUSION This meta-analysis shows that simultaneous bilateral THA accompanies fewer complications and lower total cost. Well-designed randomized controlled trials are needed to provide robust evidence.

Abstract
Background: Identification of the risk factors for surgical site infection (SSI) can be a straightforward and cost-effective measure to reduce or prevent the occurrence of SSI. However, there are no studies that revealed risk factors for SSI for traumatic upper extremity amputation. The aim of this study is to investigate the risk factors that promote SSI after surgery for traumatic upper extremity amputation using a large nationwide database. Methods: We used data from the Japan Trauma Data Bank. Diagnoses were defined using the Abbreviated Injury Scale code. We applied multivariate logistic regression to evaluate the infection risk factor. We chose age, sex, vital signs, cause and type of trauma, concomitant injury, diabetes, amputation level, Glasgow coma scale, Injury Severity Score (ISS) and blood transfusion within 24 hours following hospital arrival as confounders. Receiver operating characteristic (ROC) curve analysis was adopted to identify thresholds for change in infection risk. We also applied propensity score (PS) matching to adjust for confounding factors that may affect the outcome. Results: A total of 1,150 patients (967 males, 183 females) had traumatic upper extremity amputation. The mean patient age was 46.5 years. A total of 21 patients (1.8%) suffered from SSI. ISS, blood transfusion, systolic blood pressure (BP) and the upper extremity amputation except for finger were identified as the independent significant risk factors for SSI occurrence by the multivariate analysis (p < 0.05, p < 0.005, p < 0.05 and p < 0.005, respectively). ROC modelling revealed that patients with ISS of over 9 or systolic BP of over 160 had a risk for SSI. After PS matching, the patients with blood transfusion or systolic BP of over 160 had a significantly higher risk of infection (OR 9.0; p = 0.01 and OR 7.0; p = 0.03, respectively). Conclusions: In treating patients with these risk factors, we must be especially careful in performing thorough debridement and wound care. Level of Evidence: Level II (Therapeutic)

Reduction of Blood Loss by Intra-articular Injection of Tranexamic Acid Combined with Knee and Hip Flexion at 45° During Primary Total Knee Arthroplasty: A Randomized Controlled Trial. Orthop Surg 2020; 12:1835-1842. [PMID: 33094562 PMCID: PMC7767671 DOI: 10.1111/os.12814] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Revised: 07/09/2020] [Accepted: 08/24/2020] [Indexed: 12/01/2022] Open
Abstract
Objective To explore the hemostatic effect of intra‐articular administration of tranexamic acid (TXA) combined with knee flexion in total knee arthroplasty (TKA). Methods This randomized controlled trial was conducted at the Third Affiliated Hospital of Southern Medical University (Guangzhou, China) from January 2017 to February 2018. The patients were randomized 1:1 to the TXA group (TXA 500 mg into the joint after closure, knee, and hip flexed at 45° for 4 h) or the control group (physiological saline, with limb fully extended). The primary endpoint was postoperative hemoglobin reduction. The postoperative levels of hemoglobin were measured at four time points: 6 h after operation, and on the first, second, and third postoperative days. Calculated blood loss (CBL) at 3 days, transfusion rate, range of motion (ROM), VAS pain score, and knee circumference increment were the secondary endpoints. Ninety‐four (47/group) patients were analyzed. Results Postoperatively, there were statistically significant differences between the TXA and control groups in CBL (791 ± 212 mL vs 1175 ± 273 mL, P < 0.05). Hemoglobin reduction was significantly lower in the TXA group (2.0 ± 0.9 g/dL vs 4.5 ± 0.7 g/dL, P < 0.05). Based on the transfusion criteria, 3 out of 47 (6.4%) patients in the TXA group and 13 out of 47 (27.6%) patients in the control group received blood transfusions (P = 0.006). ROM (90.8° ± 6.2° vs 87.6° ± 6.4°, P = 0.004), VAS pain score (4.1 ± 1.1 vs 4.8 ± 1.3, P = 0.004), and KCI (2.4 ± 0.9 cm vs 3.2 ± 1.0 cm, P = 0.01) were better in the TXA group compared with thecontrols. There was no deep venous thrombosis (DVT), wound infection or other adverse events in either group. In the control group, 2 patients had a fever after blood transfusion. Conclusion Intra‐articular injection of TXA combined with knee and hip flexion at 45° can effectively attenuate CBL and hemoglobin reduction during primary TKA, without an additional adverse event.

Asian Spine J 2017; 11:880-891. [PMID: 29279742 PMCID: PMC5738308 DOI: 10.4184/asj.2017.11.6.880] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Revised: 03/22/2017] [Accepted: 04/20/2017] [Indexed: 11/12/2022] Open
Abstract
Study Design Retrospective cohort study. Purpose The purpose of this study was to assess the rate of blood transfusion after cervical fusion surgery, and its effect on complication rates. Overview of Literature Cervical spine fusions have gained interest in the literature since these procedures are now ever more frequently being performed in an outpatient setting with few complications. Methods The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients that underwent cervical fusion from 2010 to 2013. Multivariate regression analysis was used to determine postoperative complications associated with transfusion and cervical fusion. Results We identified 11,588 patients who had cervical fusion between 2010 and 2013. The rate of blood transfusion following cervical fusion found to be 1.47%. All transfused patients were found to have increased risk of venous thromboembolism (TBE) (odds ratio [OR], 3.19; 95% confidence interval [95% CI], 1.16–8.77), myocardial infarction (MI) (OR, 9.12; 95% CI, 2.53–32.8), increased length of stay (LOS) (OR, 28.03; 95% CI, 14.28–55.01) and mortality (OR, 4.14; 95% CI, 1.44–11.93). Single level fusion had increased risk of TBE (OR, 3.37; 95% CI, 1.01–11.33), MI (OR, 10.5; 95% CI, 1.88–59.89), and LOS (OR, 14.79; 95% CI, 8.2–26.67). Multilevel fusion had increased risk of TBE (OR, 5.64; 95% CI, 1.15–27.6), surgical site infection (OR, 16.29; 95% CI, 3.34–79.49), MI (OR, 10.84; 95% CI, 2.01–58.55), LOS (OR, 26.56; 95% CI, 11.8–59.78), and mortality (OR, 10.24; 95% CI, 2.45–42.71). Patients who had anterior cervical discectomy and fusion surgery and received a transfusion had an increased risk of TBE (OR, 4.87; 95% CI, 1.04–22.82), surgical site infection (OR, 9.73; 95% CI, 2.14–44.1), MI (OR, 9.88; 95% CI, 1.87–52.2), increased LOS of more than 2 days (OR, 28.34; 95% CI, 13.79–58.21) and increase in mortality (OR, 6.3; 95% CI, 1.76–22.48). While, transfused patients who had posterior fusion surgery had increased risk of MI (OR, 10.45; 95% CI, 1.42–77.12) and increased LOS of more than 6 days (OR, 4.42; 95% CI, 2.68–7.29). Conclusions Our results demonstrate that although cervical fusions can be done as outpatient procedures special precautions and investigations should be done for patients who receive transfusion after cervical fusion. These patients are demonstrated to have higher rate of MI, TBE, wound infection and mortality when compared to those who do not receive transfusion.

J Arthroplasty 2017; 32:320-325. [PMID: 27682006 DOI: 10.1016/j.arth.2016.08.026] [Citation(s) in RCA: 148] [Impact Index Per Article: 21.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2016] [Revised: 08/21/2016] [Accepted: 08/22/2016] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Blood loss occurs significantly more frequently during total hip and knee arthroplasty than among any other type of orthopedic operation, which can sometimes lead to requiring a blood transfusion. Although allogeneic blood transfusion has been identified as a risk factor for postoperative surgical-site infection following arthroplasty, results are inconclusive. The purpose of this study was to conduct a systematic meta-analysis to investigate whether having an allogeneic blood transfusion significantly increases the risk for surgical-site infection, particularly after total hip and knee arthroplasty. METHODS We performed a systematic review and meta-analysis using random-effect models. Using an electronic database search, we selected 6 studies that included data on 21,770 patients and among these studies compared the postoperative infection rate between an allogeneic blood-transfusion exposure group and a nonexposure group. We calculated the pooled odds ratios and 95% confidence intervals for the groups. RESULTS The prevalences of surgical-site infections in our pooled analyses were 2.88% and 1.74% for the transfusion and nontransfusion groups, respectively. The allogeneic blood transfusion group had a significantly higher frequency of surgical-site infections based on pooled analysis using a random-effect model (pooled odds ratio = 1.71, 95% confidence interval: 1.23-2.40, P = .002). CONCLUSION Allogeneic blood transfusion is a significant risk factor for increasing the surgical-site infection rate after total hip and knee arthroplasty.

Abstract
Study Design Retrospective cohort study. Objective To identify predictive factors for blood transfusion and associated complications in lumbar and thoracic fusion surgeries. Methods The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients who underwent lumbar or thoracic fusion from 2010 to 2013. Multivariate analysis was used to determine predictive factors and postoperative complications associated with transfusion. Results Out of 13,695 patients, 13,170 had lumbar fusion and 525 had thoracic fusion. The prevalence of transfusion was 31.8% for thoracic and 17.0% for lumbar fusion. The multivariate analysis showed that age between 50 and 60, age between 61 and 70, age > 70, dyspnea, American Society of Anesthesiologists class 3, bleeding disease, multilevel surgery, extended surgical time, return to operation room, and higher preoperative blood urea nitrogen (BUN) were predictors of blood transfusion for lumbar fusion. Multilevel surgery, preoperative BUN, and extended surgical time were predictors of transfusion for thoracic fusion. Patients receiving transfusions who underwent lumbar fusion were more likely to develop wound infection, venous thromboembolism, pulmonary embolism, and myocardial infarction and had longer hospital stay. Patients receiving transfusions who underwent thoracic fusion were more likely to have extended hospital stay. Conclusion This study characterizes incidence, predictors, and postoperative complications associated with blood transfusion in thoracic and lumbar fusion. Pre- and postoperative planning for patients deemed to be at high risk of requiring blood transfusion might reduce postoperative complications in this population.

Abstract
OBJECTIVE The effects of perioperative blood transfusion on renal functions have been studied in various studies. In this study, we investigated the effects of blood transfusion on postoperative kidney functions in patients who underwent orthopaedic surgeries. METHOD Total 136 patients who were operated for several orthopedic pathologies between June 2013 and December 2014 were evaluated. The patients were divided into two groups according to the amounts of blood transfusion. Ninety five patients (69.8%) who were transfused less than 3 units were included in Group 1 and 41 patients (30.2%) who received 3 and more units of blood were included in Group 2. RESULTS There were no statistical difference between the two groups in terms of preoperative gender, hypertension, diabetes mellitus, chronical renal failure and smoking habbits (P > 0.05). No statistical differences between the groups were seen in terms of postoperative hospital stay, pulmonary and other complications as well as mortality (P > 0.05). When the two groups were compared for blood parameters showing postoperative renal and other system functions, no statistical differences were detected (P > 0.05). CONCLUSION Blood transfusion does not have negative effects on postoperative BUN and creatinine levels in patients operated for orthopaedic pathologies.

Abstract
STUDY DESIGN Cross-sectional study using data from the Health Care Cost and Utilization Project Kids' Inpatient Database. OBJECTIVE Blood loss during spinal fusion surgery may lead to the need for transfusion. Preoperative identification of patient-related, procedure-related, or hospital-related risk factors for blood transfusion would allow for implementation of interventions designed to control excessive bleeding. SUMMARY OF BACKGROUND DATA Several studies have analyzed predictors associated with transfusion in spinal fusion. Identified predictors include age, female sex, anemia, comorbidities, number of fusion levels, osteotomy, and greater hospital volume. There have been few studies examining these predictors in children undergoing spinal fusion. METHODS Using Kids' Inpatient Database data, univariate and multivariate logistic regression was used to calculate unadjusted and adjusted odds ratios (aOR). P values of less than 0.05 were considered statistically significant. RESULTS We identified 9538 pediatric hospitalizations (patients <21 yr) with spinal fusion in 2009. Overall, 25.1% were associated with blood transfusion. The following factors were associated with transfusions: female sex (aOR 1.14, P = 0.023), black race (aOR 1.35, P = 0.005), length of hospital stay (aOR 1.03, P < 0.001), anterior approach/lumbar segment (aOR 2.11, P = 0.011) and posterior approach/lumbar segment (aOR 2.75, P < 0.001) compared with anterior approach/cervical segment, midlength fusion (aOR 1.71, P < 0.001), and long length fusion (aOR 2.85, P < 0.001) compared with short length. Higher transfusion rates were observed in patients with complications of fever and hematoma but not wound infection. CONCLUSION This study showed significant patient-, procedure-, and hospital-related predictors of allogeneic and autologous blood transfusion in spinal fusion in the pediatric age group. Higher health care resource utilization of length of stay and additional procedures are directed toward care of this transfused subgroup. Therapies to reduce blood loss and transfusion requirement are necessary for this pediatric population. LEVEL OF EVIDENCE 4.

Abstract
The aim of our study was to determine the potential influence of blood transfusion and the length of storage of packed red blood cells (RBC) on prosthetic joint infection after primary knee arthroplasty. From November 2007 to November 2009, all variables potentially associated with deep infection were registered in 1331 consecutive patients who underwent total knee arthroplasty. Infection was diagnosed in 32 (2.4%) patients. After adjusting for important variables, blood transfusion with RBCs stored >14days was the strongest predictive factor for prosthetic joint infection within 90days after primary knee arthroplasty (OR: 5.9, 95% CI: 2.6-13.2, P < 0.001). Blood saving techniques are desirable to reduce perioperative blood transfusion.

Abstract
In an initial randomised controlled trial (RCT) we segregated 180 patients to one of two knee positions following total knee replacement (TKR): six hours of knee flexion using either a jig or knee extension. Outcome measures included post-operative blood loss, fall in haemoglobin, blood transfusion requirements, knee range of movement, limb swelling and functional scores. A second RCT consisted of 420 TKR patients randomised to one of three post-operative knee positions: flexion for three or six hours post-operatively, or knee extension. Positioning of the knee in flexion for six hours immediately after surgery significantly reduced blood loss (p = 0.002). There were no significant differences in post-operative range of movement, swelling, pain or outcome scores between the various knee positions in either study. Post-operative knee flexion may offer a simple and cost-effective way to reduce blood loss and transfusion requirements following TKR. We also report a cautionary note regarding the potential risks of prolonged knee flexion for more than six hours observed during clinical practice in the intervening period between the two trials, with 14 of 289 patients (4.7%) reporting lower limb sensory neuropathy at their three-month review.

Abstract
Arthroplasty entails considerable exposure to allogenic blood transfusion. Cell salvage with washing is a contemporary strategy that is not universally used despite considerable potential benefits. We searched Embase and Medline to determine if blood salvage with washing during primary and/or revision hip and knee arthroplasty results in lower rates of transfusion and postoperative complications. We included 10 studies in our analysis, which we rated according to Downs and Black criteria. With primary knee arthroplasty, there was a reduction in transfusion rate from 22% to 76% and a 48% reduction in transfusion volume (n = 887). With primary hip arthroplasty, there was a reduction from 69% to 73% in transfusion rate and a 31% reduction in transfusion volume (n = 239). There was a significant decrease in length of hospital stay (9.6 v. 13.6 d). Studies of revision arthroplasty reported a 31%-59% reduction in transfusion volume (n = 241). The available evidence demonstrates reduced exposure to allogenic blood with the use of salvage systems. Studies have been underpowered to detect differences in infection rates and other postoperative complications. Future cost analysis is warranted.

Abstract
BACKGROUND Patients undergoing total hip or knee arthroplasty frequently receive blood transfusions. The relationship between transfusion and the risk of infection following total joint arthroplasty is unclear. In this study, we sought to examine the impact of allogeneic and autologous transfusion on the risk of acute infection following total hip and total knee arthroplasty. METHODS We performed a retrospective study of consecutive primary total knee arthroplasties and total hip arthroplasties. Patients who had a reoperation for suspected infection within three months after the arthroplasty were identified. Differences in risk factors were assessed across transfusion groups: no transfusion, autologous only, and allogeneic exposure (allogeneic with or without additional autologous transfusion). Backward-stepwise logistic regression analysis was used to compare reoperations (as outcomes) between cases with and those without allogeneic exposure. Prespecified covariates were body mass index, diabetes, an American Society of Anesthesiologists (ASA) score of >2, preoperative hematocrit, and total number of units transfused perioperatively. RESULTS We identified 3352 patients treated with a total hip or knee arthroplasty (1730 total knee arthroplasties and 1622 total hip arthroplasties) for inclusion in the study. Transfusion was given in 1746 cases: 836 of them had allogeneic exposure, and 910 had autologous-only transfusion. There were thirty-two reoperations (0.95%) for suspected infection. Between-group risk-factor differences were observed. The mean age and the rates of diabetes, immunosuppression, ASA scores of >2, and bilateral surgery were highest in the allogeneic group, as were estimated blood loss, surgery duration, and total number of units transfused (p < 0.001). In the unadjusted analyses, the rate of reoperations for suspected infection was higher in the cases with allogeneic exposure (1.67%) than in those without allogeneic exposure (0.72%) (p = 0.013). Autologous-only transfusion was not associated with a higher reoperation rate. However, multivariable logistic regression demonstrated that the total number of units transfused (p = 0.011) and an ASA score of >2 (p = 0.008)-but not allogeneic exposure-were significantly predictive of a reoperation. CONCLUSIONS Perioperative allogeneic transfusion was associated with a higher rate of reoperations for suspected acute infection. However, patients with allogeneic exposure had increased infection risk factors. After adjustment for the total number of units transfused and an ASA score of >2, allogeneic exposure was not significantly predictive of a reoperation for infection.

Abstract
OBJECTIVES To determine if the routine use of intraoperative blood cell salvage in acetabular fracture internal fixation reduces the need for allogenic blood transfusion, is cost effective, and whether it is influenced by the acetabular fracture pattern. DESIGN A retrospective study. SETTING Tertiary pelvic and acetabular reconstructive center. PATIENTS/PARTICIPANTS Patients undergoing internal fixation for acetabular fractures. RESULTS Eighty consecutive patients were reviewed, comprising 26 elementary fracture (EF) and 54 associated fracture (AF) types. The mean volume of autologous blood transfused was 484 mL. The mean volume of 561 mL of autologous blood transfused in patients with AF types was significantly greater than the mean volume of 325 mL transfused in the EF group (P = 0.007). Additional allogenic blood transfusion was required in 5 (19%) patients with EFs and 15 (28%) patients with AFs (P = 0.418). The mean cost of the blood cell salvage and additional blood products in our study was $223 (£135) for all fracture types ($174/£105 for EF and $246/£149 for AF).When treating AF types, the mean cost of using blood cell salvage was $246 (£149) as compared with the mean predicted cost of not using blood cell salvage and transfusing the equivalent of 1.7 units of allogenic blood instead, which was $463 (£281). These distributions are significantly different (P = 0.01). CONCLUSIONS The use of blood cell salvage for internal fixation surgery for acetabular fracture is cost effective, particularly when treating AF types, and its routine use is advocated to limit the need for allogenic blood transfusion.

Abstract
BACKGROUND AND OBJECTIVES Hydroxyethyl starch (HES) 130/0.4 is considered an effective plasma expander when compared to crystalloids. There is controversy around its superiority regarding hemodynamic optimization and about possible detrimental effects on coagulation. The aim of this study was to compare the effects of HES 130/0.4 to lactated Ringer solution during hip arthroplasty in adult patients under spinal anesthesia regarding intraoperative bleeding, hemodynamic parameters, coagulation profile, transfusion requirements and clinical outcomes. METHODS In this randomized, controlled trial, 48 patients scheduled for hip arthroplasty with spinal anesthesia were randomized into two groups: 24 patients were allocated to receive a preload of 15 mL.kg(-1) of HES 130/0.4 and 24 patients received a preload of 30 mL.kg(-1) lactated Ringer solution before surgery. Hemodynamic measurements, hemoglobin concentrations, biochemical parameters and coagulation tests were evaluated in three periods during surgical procedure. Patients received medical follow-up during their hospital stay and up to postoperative 30 days. Primary outcome was the requirement of red blood cell transfusion between groups during hospital stay. Secondary outcome were hemodynamic parameters, length of hospital stay, mortality and occurrence of clinical postoperative complications. RESULTS Red blood cell transfusion was required in 17% of patients in the HES group and in 46% in the Ringer group (p = .029). Postoperative infections were more frequently observed in the Ringer group (17%) compared to the HES group (0), p = .037. There were no significant differences between groups in mortality, hospital length of stay and clinical complications other than infection. CONCLUSIONS During hip arthroplasty, patients treated with hypervolemic hemodilution with hydroxyethyl starch 130/0.4 required less transfusion and presented lower infection rate compared to patients who received lactated Ringer.

Abstract
PURPOSE Intraoperative blood loss in scoliosis surgery often requires transfusions. Autogenous blood decreases but does not eliminate risks typically associated with allogenic blood transfusion. Costs associated with transfusions are significant. Tranexamic acid (TXA) has been shown to decrease blood loss in cardiac and joint surgery. Few studies have examined its use in pediatric spine surgery, and the results are inconsistent. The aim of this study was to determine whether TXA decreases intraoperative blood loss and transfusion requirements in adolescent idiopathic scoliosis patients undergoing posterior spinal fusion by a single surgeon. METHODS The medical records and operative reports of surgically treated patients with adolescent idiopathic scoliosis between 2000 and 2009 were retrospectively reviewed. The inclusion criteria were: (1) patients who underwent instrumented posterior spinal fusion, (2) had complete medical records, and (3) were treated by the same surgeon. Forty-nine patients who met the inclusion criteria were divided into two groups: Group A (25 patients) received TXA, while Group B (24 patients) did not receive TXA. RESULTS After controlling for age at the time of surgery, gender, and number of vertebral levels fused, the mean intraoperative blood loss was significantly lower in Group A (537 ml) than in Group B (1,245 ml) (p = 0.027). The mean volume of blood transfused intraoperatively was 426 and 740 ml for Group A and Group B, respectively. The difference was not statistically significant after controlling for age, gender, and number of levels fused (p = 0.078). CONCLUSION TXA significantly decreased intraoperative blood loss in posterior spinal fusions performed for adolescent idiopathic scoliosis.

Abstract
BACKGROUND Packed RBC transfusion has been postulated to increase morbidity and mortality after cardiac/general surgical operations, but its effects after lower extremity bypass (LEB) have not been studied extensively. STUDY DESIGN Using the Vascular Study Group of New England's database (2003-2010), we examined 1,880 consecutive infrainguinal LEB performed for critical limb ischemia. Perioperative transfusion was categorized as 0 U, 1 to 2 U, and ≥3 U. Cohort frequency group matching was used to compare groups of patients receiving 1 to 2 U and 0 U with patients receiving ≥3 U using age, coronary artery disease, diabetes, urgency, and indication of revascularization. Primary end points were perioperative mortality, wound infection, and loss of primary graft patency at discharge, as well as 1-year mortality and loss of primary graft patency. RESULTS In the study cohort, 1,532 LEBs (81.5%) received 0 U, 248 LEBs (13.2%) received 1 to 2 U, and 100 LEBs (5.3%) received ≥3 U transfusion. In the study cohort and group frequency matched cohort, transfusion was associated with significantly higher perioperative wound infection (0 U:4.8% vs 1 to 2 U: 6.5% vs ≥3 U: 14.0%; p = 0.0004) and graft thrombosis at discharge (4.5% vs 7.7% vs 15.3%; p < 0.0001). At 1 year, there were no differences in infection or graft patency. In multivariate analysis, transfusion was independently associated with increased perioperative wound infection in the study cohort and group frequency matched cohort (1 to 2 U vs 0 U: adjusted odds ratio [OR] = 1.4; 95% CI, 0.8-2.5; p = 0.263; ≥3 U vs 0 U: OR = 3.5; 95% CI, 1.8-6.7; p = 0.0002; overall p = 0.002) and increased graft thrombosis at discharge (1 to 2 U vs 0 U: OR = 2.1; 95% CI, 1.2-3.6; p = 0.01; ≥3 U vs 0 U: OR = 4.8; 95% CI, 2.5-9.2; p < 0.0001, overall p < 0.0001). CONCLUSIONS Perioperative transfusion in patients undergoing LEB is associated with increased perioperative wound infection and graft thrombosis. From this observational study, it appears transfusion does not have major consequences during mid-term follow-up, but the presumed benefits of blood replacement should be weighed carefully because of the increased risk of perioperative complications with transfusion.

Abstract
BACKGROUND Surgeon case-volume predicts a variety of patient outcomes. We hypothesize that surgeon case-volume predicts RBC transfusion across different surgical procedures. METHODS We performed a cohort study of 372,670 in-patient surgical cases in the 52 non-federal hospitals in Maryland between 2004 and 2005. The main outcome measure was relative risk of receiving a transfusion. RESULTS Overall, 13.9% of patients received a transfusion. Patients seen by the highest case-volume surgeons (>161 cases/y) were more likely to receive a transfusion (16% versus 11%, P < 0.01) compared with middle case-volume surgeons (89-161 cases/y). After adjusting for confounders, the highest case-volume patients were still at increased risk of transfusion [relative risk (RR) 1.10, 1.07-1.14]. This result was true across many surgery types. CONCLUSIONS Surgeon case-volume is independently associated with the likelihood of RBC transfusion across a broad range of surgical procedures. Future efforts should be directed towards studying and standardization of transfusion practices.

Abstract
In a previous prospective study, we confirmed that transfusion-related immunosuppression predisposes to postoperative infections, impairs the postoperative healing of wound and thereby prolongs hospitalization. This increases the well-known risks, such as transmission of infection or transfusion reactions, and has obliged us to revise our transfusion guidelines. We used a relational database containing information about 28,861 orthopedic surgery patients was used to determine when and how to improve these guidelines for transfusions. The survey showed the circumstances surrounding a high incidence of allogenic red cell infusions: failure to follow the guidelines, the preoperative use of nonselective NSAIDs, low preoperative Hb level, failure to retrieve blood, and high cut-off values for allogenic red cell transfusion. The first step was to determine the Hb level before giving red cell infusions and ensure compliance with predefined cut-off values. Subsequent measures included: use of COX 2-selective NSAIDs alone in the perioperative period; erythropoietin and iron therapy when the Hb level fell below 13 g/dL; use of cell salvage during and after surgery; administration of aprotinin to patients expected to have a high blood loss. The type of anesthesia had no blood-sparing effect. Although these steps can not be regarded as a new approach, we show that by following a strict rules with appropriate steps and in a concerted fashion, the use of allogenic red blood cells was reduced by 80%. Moreover, the amount of blood saved had other effects--e.g., the incidence of deep wound infections was reduced by 40%. The outcome is described in an algorithm summarizing the steps in a comprehensive perioperative diagram for giving blood.

Abstract
Intraoperative blood loss requiring allogenic blood transfusion (ABT) is a common problem in major orthopedic surgery. Since transfusion related side effects up to fatal consequences due to blood type incompatibility cannot be excluded completely, it is desirable to reduce the amount of blood loss and transfusions to a minimum. Encouraging results in the application of aprotinin, a natural protease-inhibitor with antifibrinolytic, bleeding-reducing properties, in thoracic-, heart- and abdominal surgery led to the use of aprotinin also in orthopedic surgery. One important safety issue in the use of aprotinin in orthopedic surgery is a possible negative effect on the osseous integration of an implant due to the multiple interactions of aprotinin with several enzymatic systems. In this study, we therefore investigated the influence of aprotinin on the osseous ingrowth of a titanium-implant in a rat model. Forty female Sprague-Dawley rats underwent unilateral retrograde nailing of the femur. Animals were divided in two groups, one receiving i.v. aprotinin intraoperatively, the other group receiving the same amount as saline solution. After 56 days animals were killed and from each group half of the femora were prepared for biomechanical testing, the other half for histological examination. The push-out experiment revealed no significant difference between the aprotinin-group and the control-group, both showing comparable shear stresses. In addition, the histomorphometrical analysis showed comparable implant integration between both groups. The results demonstrate that perioperative aprotinin application has no negative effect on osseous implant integration in a rat model.

Abstract
INTRODUCTION Patients undergoing total hip replacement (THR) regularly receive allogenic blood transfusions. The infusion of allogenic blood exposes the recipient to significant risks including the transmission of infection, anaphylactic and haemolytic reactions. The purpose of this study was to determine the effect of introducing a system to retransfuse salvaged drainage blood in patients undergoing primary THR. PATIENTS AND METHODS We reviewed records of 109 consecutive patients who underwent THR following the introduction of the ABTrans autologous retransfusion system at our institution in January 2000. For comparison, we reviewed the medical records of 109 patients who underwent the same procedure immediately before the introduction of the retransfusion system. RESULTS Overall, 9% of patients treated with blood salvage and 30% treated without blood salvage required allogenic blood transfusions. Patients treated with the salvage system had significantly smaller haemoglobin drops in the peri-operative period (difference 0.56 g/dl; P = 0.001). The overall cost of using the retransfusion system was similar to that of routine vacuum drainage when the savings of reduced allogenic blood transfusion were taken into account. CONCLUSIONS The retransfusion of postoperative drainage blood is a simple, effective and safe way of providing autologous blood for patients undergoing primary THR.

Abstract
Colorectal cancer is the second-leading cause of cancer-related death in the US. The prognosis of advanced colorectal cancer remains poor in spite of the advances obtained in recent years with new therapeutic agents, new approaches in surgical procedures and new diagnostic methods. Currently, colorectal cancer is the second most common cancer in Europe both in terms of incidence and mortality. Approximately 90% of all cancer deaths arise from the metastatic dissemination of primary tumors. It is a matter of vital importance whether perioperative blood transfusion promotes tumor recurrence and morbidity. This paper reviews the relevant medical literature published in English language on the theoretical background, methodological problems, results, as well as the possible clinical impact of blood transfusions in colorectal surgery with well-controlled trials. Searches were last update August 2007.

Abstract
The purpose of this study was to examine factors associated with the utilization and cost of blood transfusion during and post-spinal fusion surgery. A retrospective, observational study of 42,029 inpatients undergoing spinal fusion surgery in United States hospitals participating in the Perspective( Comparative Database for inpatient use was conducted. Descriptive analysis, logistic regression, and ordinary least squares (OLS) regression were used to describe the factors associated with the use and cost of allogeneic blood transfusion (ABT). Hospitalization costs were $18,690 (SD=14,159) per patient, erythropoietin costs were $85.25 (SD=3,691.66) per patient, and topical sealant costs were $414.34 (SD=1,020.06) per patient. Sub-analysis of ABT restricted to users revealed ABT costs ranged from $312.24 (SD=543.35) per patient with whole blood to $2,520 (SD=3,033.49) per patient with fresh frozen plasma. Patients that received hypotensive anesthesia (OR,1.61; 95% CI, 1.47-1.77), a volume expander (OR,1.95; 95% CI, 1.75-2.18), autologous blood (OR, 2.04; 95% CI, 1.71-2.42), or an erythropoietic agent (OR=1.64; 95% CI, 1.27-2.12) had a higher risk of ABT. Patients that received cell salvage had a lower risk of transfusion (OR=0.40; 95% CI, 0.32-0.50). Most blood avoidance techniques have low utilization or do not reduce the burden of transfusion associated with spinal fusion.

Abstract
AIM Postoperative complications following primary total knee replacement performed between 2000 and 2002 were assessed to determine perioperative patient- and procedure-related risks associated with the procedure. METHODS For this analysis, the data collected during postoperative hospitalization for 17,644 total knee arthroplasties were assessed. The analysis included two steps. First, using logistic regression, we identified and quantified significant risk factors for the occurrence of general postoperative complications. Second, univariate analysis was utilized to qualitatively and quantitatively analyze the influence of these significant risk factors on the occurrence of major complications (hematoma, cardiovascular complication, deep venous thrombosis, pulmonary embolism, joint infection, and pneumonia). RESULTS General postoperative complications were reported in 11.3%. Major postoperative complications occurred in 7.2% with hematoma in 2.9%, cardiovascular complications in 1.8%, deep venous thrombosis in 1.2%, pulmonary embolism in 0.2%, joint infection in 0.8%, and pneumonia in 0.3%. Patient-related risk factors such as age, surgery time, gender, high ASA classification as well as procedure-related risk factors such as allogeneic blood transfusions and lateral release significantly increased the rate of postoperative complications. Males were more prone to hematoma, joint infection, and pneumonia in the immediate postoperative course than females, who were more in danger of developing deep venous thrombosis. Allogeneic blood transfusions increased the risk for postoperative hematoma, infection, and cardiovascular complication. Regional anesthesia was shown to decrease the risk for the occurrence of postoperative deep venous thrombosis and pulmonary embolism. CONCLUSIONS Postoperative complications in total knee replacement are increased in males and elder patients. Increased time of surgery and allogeneic blood transfusions also represent important risk factors for postoperative complications following primary total knee replacement.

Abstract
Anaemia is characterised by an insufficient number of red blood cells (RBCs) and might occur for different reasons, e.g. surgical procedures are often with associated blood loss. Patients who suffer from anaemia have the option of treatment with blood transfusion or medical treatment. In this study, the societal cost, for the case of Sweden, of RBC transfusion using three different techniques, i.e. allogeneic, autologous and intraoperative transfusion, was estimated. The analysis was based on information from interviews with hospital staff at large Swedish hospitals and from published data. The average cost for a 2 units transfusion was found to be Swedish kronor (SEK) 6330 (702 Euro) for filtered allogeneic RBCs and SEK 5394 (598 Euro) for autologous RBCs for surgery patients. Transfusion reactions accounted for almost 35 per cent of the costs of allogeneic RBC transfusions. The administration cost was found to be much higher for autologous transfusions compared with allogeneic transfusions. The cost of intraoperative erythrocyte salvage was calculated to be SEK 2567 (285 Euro) per transfusion (>4 units).

Abstract
BACKGROUND AND OBJECTIVE Preoperative epoetin alfa administration decreases transfusion requirements and may reduce transfusion complications, such as postoperative infection due to immune suppression and thus hospitalization time. This study examined the impact of preoperative epoetin alfa administration on postoperative recovery and infection rate. METHODS In an open randomized controlled multicentre trial in patients undergoing orthopaedic surgery, the effects of preoperative administration of epoetin alfa vs. routine care were compared in six countries. Haemoglobin (Hb) values, transfusions, time to ambulation, time to discharge, infections and safety were evaluated in patients with preoperative Hb concentrations 10-13g dL(-1) (on-treatment population: epoetin n = 460; control n = 235), from study entry until 4-6 weeks after surgery. Outcome was also compared in patients with and without transfusion. RESULTS Epoetin-treated patients had higher Hb values from the day of surgery until discharge (P < 0.001) and lower transfusion rates (12% vs. 46%; P < 0.001). Epoetin treatment delivered no significant effect on postoperative recovery (time to ambulation, time to discharge and infection rate). However, the time to ambulation (3.8+/-4.0 vs. 3.1+/-2.2days; P < 0.001)and the time to discharge (12.9+/-6.4 vs. 10.2+/-5.0 days; P < 0.001) was longer in the transfused than in the non-transfused patients. Side-effects in both groups were comparable. CONCLUSIONS Epoetin alfa increases perioperative Hb concentration in mild-to-moderately anaemic patients and thus reduces transfusion requirements. Patients receiving blood transfusions require a longer hospitalization than non-transfused patients.

Abstract
BACKGROUND The primary objective of this study was to assess the number of erythropoietin (EPO) injections required to reach a hematocrit (Ht) of 40% in moderately anemic patients. The secondary objective was to compare this strategy with autologous blood donation (ABD) in elective orthopedic surgery in terms of red blood cell (RBC) production. STUDY DESIGN AND METHODS 93 patients with a baseline Ht between 30 and 39% were randomized into two groups the day of the preoperative assessment. In the EPO group, patients received 40,000 UI/week sc until they reached a maximal Ht of 40%. In the ABD group, a RBC pack was collected every week as long as the Ht was above 33%. RESULTS Two EPO injections were necessary to reach a 40% Ht in 63% of the patients. It was possible to collect two RBC packs in 45% of the patients in the ABD group. Volume of RBC production was significantly higher in the EPO group: 268 +/- 142 mL vs 141 +/- 129 (P = 0.0001). In the EPO group, Ht was significantly higher on days one and three after surgery and at discharge. The energy score was better in the EPO group. In the ABD group, 12.6% patients vs 6.5% in the EPO group received allogeneic transfusion (ns). CONCLUSION Only two EPO injections were sufficient to reach a Ht of 40% in the majority of patients. Therefore, to improve cost/effectiveness, the number of EPO injections should be related to baseline Ht instead of the four injections recommended in the product monograph.

Abstract
BACKGROUND This study was designed to obtain data on the incidence of postoperative infection in patients undergoing elective orthopedic surgery and receiving white blood cell (WBC)-filtered blood components prepared according to current standards. STUDY DESIGN AND METHODS A total of 308 consecutive orthopedic patients who opted for preoperative autologous blood donation (PAD) for primary unilateral hip and knee replacement surgery were enrolled in a prospective observational study of the incidence of postoperative infection. Patients with contraindications for PAD or with any infectious disease were not included in the study. To identify probably confounding factors, differences between patient groups were analyzed first. Identified factors, which differed between groups, and variables describing blood supply were further tested in uni- and multivariate logistic regression analysis for their independent influence on development of postoperative infection. Infection rates were compared on the basis of actual transfusion groups. RESULTS Of the 308 study patients, 101 were not transfused, 85 received their PAD, 100 received allogeneic WBC-filtered red blood cells (RBCs), and 22 were given autologous RBCs and additionally allogeneic WBC-filtered RBCs. Overall the infection rate was 6.82 percent (21/308). Infection rates varied significantly between transfusion groups (no transfusion, 6.9%; autologous RBCs, 1.2%; allogeneic WBC-filtered RBCs, 12.0%; both transfusion types, 4.6%; p = 0.03). Allogeneic recipients showed significantly more infections compared to autologous recipients (p = 0.0053). Multivariate regression analysis confirmed transfusion of allogeneic WBC-filtered RBCs as an independent variable predicting postoperative infection (odds ratio, 23.65; confidence interval, 1.3-422.1; p = 0.01). CONCLUSION Differences in postoperative infection rates between allogeneic and autologous recipients are still observable, although universal WBC filtration has been introduced into clinical practice.

Abstract
STUDY DESIGN A historic cohort to determine short-term complications after 115 corrective osteotomies of the cervical and lumbar spine in patients with ankylosing spondylitis. OBJECTIVES To describe the nature of complications of spinal osteotomies and sequelae. SUMMARY OF BACKGROUND DATA Little is known about the rate and nature of complications after spinal osteotomy in these patients. METHODS A chart review of 106 patients (age, 21-82 years) was conducted. The following surgical techniques were performed: cervical-thoracic extending osteotomy at C6-Th1 (n = 22), lumbar closing-wedge osteotomy (n = 62), polysegmental lumbar osteotomy (n = 20), or a combined anterior-posterior lumbar correction (n = 11). RESULTS Many complications (7.8% permanent neurologic deficit, 9.6% deep wound infections, and 10.4% major general complications) occurred after performing a spinal correction. Since 1998, there is a tendency for a lower rate of infections but a higher rate of neurologic and major general complications. Because of 27% deep wound infections and 18% major general complications, the technique of combined anterior and posterior surgery has been abandoned. CONCLUSION High complication rates in this group of patients are partly due to the difficult surgery but also to the underlying disease. The surgery should be concentrated in specialized centers.

Abstract
Storing autologous blood as whole blood (WB) has been proposed for increasing the cost-effectiveness of preoperative autologous blood donation programmes. However, experimental data suggest that autologous leucocytes might lead to immunomodulation similar to the effect attributed to allogeneic leucocytes. In a retrospective analysis, the postoperative outcome of 120 patients undergoing elective orthopaedic surgery and having donated up to two units of autologous WB (AWB) was compared with that of a control group of 52 patients, whose autologous donation had been processed into buffy coat-depleted red cell concentrates (RCC). At least one autologous unit, but no allogeneic units, had been transfused in all analysed patients. Donation schemes were equally efficacious in both groups. There was no significant difference in postoperative infection rates between the two groups. Overall rates were 7.7% in the RCC group and 8.3% in the WB group. Surgical, thromboembolic and other recorded complications, length of postoperative hospital stay and days of the use of antibiotics were also not significantly different between the two groups. The results of this study suggest that transfusion of up to two units of unmodified AWB is as efficacious as the transfusion of autologous RCC and does not negatively influence the postoperative outcome in elective orthopaedic surgery.

Abstract
BACKGROUND A before and after study was undertaken to investigate the effect of universal leukoreduction (ULR) in the UK on postoperative length of hospital stay (LOS) and infections. STUDY DESIGN AND METHODS Consecutive patients undergoing elective coronary artery bypass grafting or total hip and/or knee replacement in 11 hospitals received non-WBC-reduced RBCs before implementation of ULR (T1, n=997) or WBC-reduced RBCs after implementation of ULR (T2, n=1098). RESULTS Patients in T1 and T2 were comparable except patients in T2 received on average more units of RBCs but had lower discharge Hct levels. Postoperative LOS (T1, 10 +/- 8.9 days; T2, 9.6 +/- 6.9 days) and the proportion of patients with suspected and proven postoperative infections (T1, 21.0%; T2, 20.0%) were unchanged before and after ULR (LOS, hazard ratio 1.01, 95% CI 0.92-1.10; infections, OR 0.83, 95% CI 0.77-1.02). Subgroup analysis showed no significant interaction between storage age or dose of blood on responsiveness of primary outcomes to ULR. Secondary outcomes were unchanged overall. Analysis by surgical procedure gave conflicting results with both increased mortality (p=0.031) and an increased proportion of cardiac patients with proven infections (p=0.004), whereas the proportion of orthopedic patients with proven infections was reduced (p=0.002) after ULR. CONCLUSION Implementation of ULR had no major impact on postoperative infection or LOS in patients undergoing elective surgical procedures who received transfusion(s). Smaller effects, either detrimental or beneficial of ULR, cannot be excluded.

Abstract
BACKGROUND AND OBJECTIVES The aim of this study was to evaluate whether leucocyte-reducing filters influenced complement activation and the formation of pro-inflammatory cytokines in autotransfusion drain blood after knee arthroplasty. MATERIALS AND METHODS Twenty-three patients undergoing knee arthroplasty were divided into two groups. All patients were given salvage blood postoperatively. In Group A, a leucocyte filter was connected between the wound and the drain blood container. In Group B the drain blood was not leucocyte filtered. Complement split products and cytokines were analysed in circulating blood and in drain blood, together with blood-cellular differential counts. RESULTS Drain blood showed activation vs. venous blood, with elevated concentrations of C3a, SC5b-9, interleukin (IL)-6, IL-8, polymorphonuclear (PMN) elastase and tumour necrosis factor-alpha (TNF-alpha) (P<0.05 to P<0.001). The leucocyte filter reduced TNF-alpha (P<0.01), but triggered complement activation (P<0.05). Room-temperature incubation increased the concentration of IL-8 (P<0.01), which was seen in both venous and drain blood. The leucocyte filter prevented formation of IL-8 (P<0.01). In drain blood at 24 h the inflammatory reactions accelerated (P<0.05-0.001), although the filter reduced the leucocyte counts and TNF-alpha concentrations. CONCLUSIONS The leucocyte filter reduced IL-8 and TNF-alpha in drain blood, but at the same time triggered complement activation. Incubation affected the inflammatory spectrum of both drain blood and control venous blood, and the filtering reduced this activation.

Abstract
BACKGROUND The purpose of this study was to assess current practices in blood management in elective orthopedic surgery in Europe. STUDY DESIGN AND METHODS For this 225-center prospective survey, data were collected on 3996 patients. Actual perioperative blood loss was compared to preoperative estimates. Differences in Hb levels and other outcome variables for patients receiving allogeneic versus autologous transfusions were evaluated. The probability of allogeneic transfusion based on selected predictor variables was estimated. RESULTS A total of 2640 (67%) hip and 1305 (33%) knee arthroplasty patients were evaluated. Estimated blood loss (median, 750 mL) was significantly lower than computed blood loss (median, 1944 mL). A total of 2762 (69%) patients received transfusions, including 1393 (35%) autologous-only and 1024 (25%) allogeneic-only. The probability of allogeneic transfusion decreased with increasing baseline Hb, but differentially so for men and women. Transfusion triggers were Hb levels of 8.93 +/- 1.83 g per dL for allogeneic transfusions, and 21 percent of these occurred when the Hb level was greater than 10 g per dL. Autologous blood transfusion was associated with a significantly lower rate (1%) of wound infections than allogeneic blood transfusion (4.2%). CONCLUSION Accurate assessment of preoperative Hb levels, better estimation of perioperative blood loss, efficient use of autologous blood, adherence to transfusion guidelines, and pharmacologic alternatives contribute to effective and comprehensive blood and anemia management.

Abstract
STUDY DESIGN A retrospective review was performed. OBJECTIVE To determine clinical predictors of allogeneic and autologous red cell transfusion in children and adolescents undergoing spinal fusion surgery. SUMMARY OF BACKGROUND DATA Blood loss during spinal fusion surgery often results in the need for transfusion therapy. Preoperative identification of patients at increased risk for red cell transfusion would allow more specific use of interventions designed to control excessive bleeding. METHODS The medical records of all patients undergoing posterior spinal fusion surgery at a single institution between July 1, 1999 and June 30, 2001 were reviewed. Logistic and stepwise multiple regression analyses were used to identify predictors of allogeneic and autologous red cell transfusion during the operative and postoperative periods. RESULTS Posterior spinal fusion surgery was performed in 107 patients (males, 42%) with a median age of 13.7 years (range, 1-20 years). The median intraoperative blood loss was 22 mL/kg (range, 4.4-72 mL/kg). Blood transfusion involved 63 patients (59%) who received 17 mL/kg (range, 3-65 mL/kg) of allogeneic packed red blood cells and 14 patients (13%) who received 7 mL/kg (range, 4-19 mL/kg) of autologous red cells donated before surgery. Underlying neuromuscular disease, lower body weight, and a higher number of vertebrae fused independently predicted a greater number of allogeneic red cells transfused (R2 = 0.53). The amount of autologous blood donated before surgery predicted the number of autologous red cells transfused (R2 = 0.56). CONCLUSIONS Allogeneic red cell transfusion often is required for small patients with underlying neuromuscular disease who undergo extensive spinal fusion surgery. These patients may be less able to donate autologous blood before surgery. Newer therapies to reduce blood loss and transfusion requirement are needed most for this population.

Abstract
Transfusion is associated with multiple risks and morbidities. Little is known, however, about preoperative predictors of transfusion in gastrointestinal surgery patients. To identify factors that influence transfusion practices, we analyzed hospital discharge data from colorectal cancer surgery patients in Maryland between 1994 and 2000 (n = 14,052). The primary outcome variable was whether or not patients received a blood product ("Any Transfusion"). Characteristics independently associated with an increased risk of receiving Any Transfusion included: advanced age (>80 yr: OR 2.3; 95% CI 1.9-2.9; 70-79 yr: OR 1.6; 95% CI 1.4-2.0 vs. <60 yr), moderate to severe liver disease (OR 2.5; 95% CI 1.5-4.2), mild liver disease (OR 2.1; 95% CI 1.5-2.9), diabetes with complications (OR 2.1; 95% CI 1.6-2.6), chronic renal disease (OR 2.1; 95% CI 1.4-3.0), female gender (OR 1.3; 95% CI 1.2-1.5), chronic pulmonary disease (COPD) (OR 1.3; 95% CI 1.1-1.4), and metastatic disease (OR 1.2; 95% CI 1.1-1.4). Patients at hospitals with an annual case volume in the highest quartile were at an increased risk for receiving Any Transfusion (OR 2.1; 95% CI 1.3-3.4) and those with surgeons in the highest volume quartile (>12 cases/yr) were at a decreased risk (OR 0.8; 95% CI 0.6-0.99). The association between greater surgeon case volume and low transfusion rates was seen in all but the very high volume hospitals (>74 cases/yr). Blood product transfusion was associated with a 2.5-fold (95% CI 2.1-3.1) increased mortality, 3.7 day (95% CI 2.1-3.1) increase in hospital length of stay, and a 7120 dollars (95% CI 6472 dollars-7769 dollars) increase in total charges compared to patients that did not receive Any Transfusion. This data can be used by providers in discussions with patients regarding the risks for transfusion and in identifying patients in whom strategies to reduce transfusions should be evaluated.

Abstract
BACKGROUND The purpose of this study was to identify preoperative patient, hospital, and surgeon characteristics associated with transfusion for spinal surgery. STUDY DESIGN AND METHODS Discharge data were obtained from 39 Maryland hospitals for adult patients (n = 3988) who had a primary procedure code for spinal surgery between July 1997 through June 2000, and with these codes, surgeons and hospitals were characterized by annual patient volume. Outcome variables included any allogeneic transfusion, any transfusion, RBCs, autologous blood, FFP, or platelet transfusion. Logistic regression was used for univariate and multivariate analyses. RESULTS Characteristics independently associated with an increased risk of receiving any allogeneic transfusion (n = 786) included age >54 (OR, 1.6; 95% CI, 1.3-2.1), age >66 (OR, 2.7; 95% CI, 2.0-3.5), female sex (OR, 1.6; 95% CI, 1.2-2.0), diabetes with chronic complications (OR, 2.5; 95% CI, 1.3-4.9), and metastatic tumor (OR, 4.9; 95% CI, 2.3-10.5), emergency room admission (OR, 2.3; 95% CI, 1.4-3.8), and greater hospital volume (OR, 4.0; 95% CI, 1.8-8.6). Characteristics independently associated with increased autologous transfusions (n = 574) included white race (OR, 1.7; 95% CI, 1.2-2.4), female sex (OR, 1.4; 95% CI, 1.1-1.8), and greater surgeon volume (OR, 3.5; 95% CI, 1.4-9.1). DISCUSSION This information can be used to provide informed risk-benefit discussions with patients regarding the risk for blood transfusion as well as to target high-risk patients and institutions for interventions to reduce the risk of exposure to blood components.

Abstract
BACKGROUND AND OBJECTIVES Transfusion-induced immunomodulation by autologous blood is probably related to the buffy coat. Hence, in the present study, phagocytotic and oxidation activities of peripheral blood cells were investigated in hip arthroplasty patients exposed to autologous blood. MATERIALS AND METHODS Blood from 60 autologous donors was allocated at random to storage as whole blood (WB) or as buffy coat-poor packed red cells and fresh-frozen plasma (RCP). Phagocytotic and oxidation activities of neutrophils and monocytes, incidence of infections and length of hospital stay were compared among the groups of transfused (WB and RCP) and non-transfused (NT) patients. RESULTS Phagocytotic activities of neutrophils and monocytes were not significantly different among the WB, RCP and NT groups. CONCLUSION In the perioperative setting, a specific cellular immune response to autologous transfusion is not detectable.

Abstract
OBJECTIVE To identify the risk factors for surgical site infection (SSI) in patients undergoing elective resection of the colon and rectum. SUMMARY BACKGROUND DATA SSI causes a substantial number of deaths and complications. Determining risk factors for SSI may provide information on reducing complications and improving outcome. METHODS The authors performed a prospective study of 2,809 consecutive patients undergoing elective colorectal resection via laparotomy between February 1995 and December 1998 at a single institution. The outcome of interest was SSI, which was classified as being incisional or organ/space with or without clinical leakage. A likelihood ratio forward regression model was used to assess the independent association of variables with SSIs. RESULTS The overall SSI, incisional SSI, and organ/space SSI with and without clinical anastomotic leakage rates were 4.7%, 3%, 2%, and 0.8%, respectively. Risk factors for overall SSI were American Society of Anesthesiology (ASA) score 2 or 3 (odd ratio [OR] = 1.7), male gender (OR = 1.5), surgeons (OR = 1.3-3.3), types of operation (OR = 0.3-2.1), creation of ostomy (OR = 2.1), contaminated wound (OR = 2.9), use of drainage (OR = 1.6), and intra- or postoperative blood transfusion (1-3 units, OR = 5.3; >/=4 units, OR = 6.2). However, SSIs at specific sites differed from each other with respect to the risk factors. Among a variety of risk factors, only blood transfusion was consistently associated with a risk of SSI at any specific site. CONCLUSIONS In addition to ASA score and surgical wound class, blood transfusion, creation of ostomy, types of operation, use of drainage, sex, and surgeons were important in predicting SSIs after elective colorectal resection.

Abstract
BACKGROUND Storage of blood as packed RBCs and FFP is standard practice in allogeneic transfusion. Separation into components has been proposed for autologous transfusion, as well, but beneficial effects have not yet been shown. STUDY DESIGN AND METHODS Twenty-four healthy male volunteers were randomly assigned to receive 1 unit of either autologous RBCs and FFP (RCP group) or WB (WB group) after 49 or 35 days of storage, respectively. The immune response was analyzed by ELISA for IL-6, C3a, terminal complement complex SC5b-9, TNF-alpha, and neopterin. Differential WBC counts and the phagocytosis of neutrophils and monocytes were measured by flow cytometry. RESULTS Cell counts of monocytes (0.85 x 10(3) ng/microL) [corrected] and neutrophils (6.9 x 10(3) ng/microL) [corrected] increased 30 minutes after WB transfusion and then returned to close to the baseline values seen in the RCP group (0.47 and 2.9 x 10(3) ng/microL [corrected], respectively) throughout the monitored period (p<0.05). C3a (169 vs. 116 ng/microL) [corrected] and IL-6 (29 vs. 6 pg/mL) reached higher plasma concentrations in the WB group (n = 11) than in the RCP group (n = 10). Phagocytosis of opsonized Escherichia coli was increased in neutrophils and monocytes and lasted up to 7 days after the transfusion of whole blood. CONCLUSION Autologous WB induces a modest immunomodulation, but this effect is not observed upon transfusion of autologous blood components.
