BMC Anesthesiol 2023; 23:211. [PMID: 37330483 PMCID: PMC10276442 DOI: 10.1186/s12871-023-02180-3] [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: 03/11/2023] [Accepted: 06/15/2023] [Indexed: 06/19/2023] Open
Abstract
BACKGROUND Intraoperative autologous transfusion (IAT) has been used in scoliosis surgery for decades; however, its cost-effectiveness remains debatable. This study aimed to evaluate the cost-effectiveness of IAT in adolescent idiopathic scoliosis (AIS) surgery and identify risk factors of massive intraoperative blood during this surgery. METHODS The medical records of 402 patients who underwent AIS surgery were reviewed. The patients were divided into different groups according to the intraoperative blood loss volume (group A: ≥500 to < 1000 mL, B: ≥1,000 to < 1,500 mL, and C: ≥1,500 mL) and whether IAT was used (i.e., IAT and no-IAT groups). The volume of blood loss, volume of transfused allogeneic red blood cells (RBC), and RBC transfusion costs were analysed. Univariate and multivariate logistic regression analyses were used to identify the independent risk factors of massive intraoperative blood loss (≥ 1,000 mL and ≥ 1,500 mL). A receiver operating characteristic (ROC) curve was used to analyse the cut-off values of the factors contributing to massive intraoperative blood loss. RESULTS In group A, no significant difference was observed in the volume of allogeneic RBC transfused during and after procedure between the IAT and no-IAT groups; however, total RBC transfusion costs was significantly higher in the IAT group. In groups B and C, the patients in the IAT group compared with those in the no-IAT group had a lower volume of allogeneic RBC transfused during the operation and on the first day after the operation. However, in group B, the total RBC transfusion cost in the patients who used IAT was significantly higher. In group C, total RBC transfusion cost in the patients who used IAT was significantly lower. The number of fused vertebral levels and Ponte osteotomy were found to be independent risk factors for massive intraoperative blood loss. ROC analysis showed that more than eight and 10 fused vertebral levels predicted ≥ 1,000 mL and ≥ 1,500 mL intraoperative blood loss, respectively. CONCLUSION The cost-effectiveness of IAT in AIS was related to the volume of blood loss, and when the blood loss volume was ≥ 1,500 mL, IAT was cost-effective, drastically reducing the demand for allogeneic RBC and total RBC transfusion cost. The number of fused vertebral levels and Ponte osteotomy were independent risk factors for massive intraoperative blood loss.

Abstract
OBJECTIVES To collect and present the recently published methods of quantifying blood loss (BL) in orthopaedic trauma. DATA SOURCES A systematic review of English-language literature in PubMed, Cochrane Library, and Scopus databases was conducted according to the PRISMA guidelines on articles describing the methods of determining BL in orthopaedic trauma published since 2010. STUDY SELECTION English, full-text, peer-reviewed articles documenting intraoperative BL in an adult patient population undergoing orthopaedic trauma surgery were eligible for inclusion. DATA EXTRACTION Two authors independently extracted data from the included studies. Articles were assessed for quality and risk of bias using the Cochrane Collaboration's tool for assessing risk of bias and ROBINS-I. DATA SYNTHESIS The included studies proved to be heterogeneous in nature with insufficient data to make data pooling and analysis feasible. CONCLUSIONS Eleven methods were identified: 6 unique formulas with multiple variations, changes in hemoglobin and hematocrit levels, measured suction volume and weighed surgical gauze, transfusion quantification, cell salvage volumes, and hematoma evacuation frequency. Formulas included those of Gross, Mercuriali, Lisander, Sehat, Foss, and Stahl, with Gross being the most common (25%). All formulas used blood volume estimation, determined by equations from Nadler (94%) or Moore (6%), and measure change in preoperative and postoperative blood counts. This systematic review highlights the variability in BL estimation methods published in current orthopaedic trauma literature. Methods of quantifying BL should be taken into consideration when designing and evaluating research.

Tranexamic acid use decreases transfusion rate in children with cerebral palsy undergoing proximal femoral varus derotational osteotomy. Medicine (Baltimore) 2022; 101:e28506. [PMID: 35029205 PMCID: PMC8757939 DOI: 10.1097/md.0000000000028506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 12/14/2021] [Indexed: 01/05/2023] Open
Abstract
Previous studies demonstrated the safety of tranexamic acid (TXA) use in cerebral palsy (CP) patients undergoing proximal femoral varus derotational osteotomy (VDRO), but were underpowered to determine if TXA alters transfusion rates or estimated blood loss (EBL). The purpose of this study was to investigate if intraoperative TXA administration alters transfusion rates or EBL in patients with CP undergoing VDRO surgery.We conducted a retrospective review of 390 patients with CP who underwent VDRO surgery between January 2004 and August 2019 at a single institution. Patients without sufficient clinical data and patients with preexisting bleeding or coagulation disorders were excluded. Patients were divided into 2 groups: those who received intraoperative TXA and those who did not.Out of 390 patients (mean age 9.4 ± 3.8 years), 80 received intravenous TXA (TXA group) and 310 did not (No-TXA group). There was no difference in mean weight at surgery (P = .25), Gross Motor Function Classification System level (P = .99), American Society of Anesthesiologist classification (P = .50), preoperative feeding status (P = .16), operative time (P = .91), or number of procedures performed (P = .12) between the groups. The overall transfusion rate was lower in the TXA group (13.8%; 11/80) than the No-TXA group (25.2%; 78/310) (P = .04), as was the postoperative transfusion rate (7.5%; 6/80 in the TXA group vs 18.4%; 57/310 in the No-TXA group) (P = .02). The intraoperative transfusion rate was similar for the 2 groups (TXA: 7.5%; 6/80 vs No-TXA: 10.3%; 32/310; P = .53). The EBL was slightly lower in the TXA group, although this was not significant (TXA: 142.9 ± 113.1 mL vs No-TXA: 177.4 ± 169.1 mL; P = .09). The standard deviation for EBL was greater in the No-TXA group due to more high EBL outliers. The percentage of blood loss based on weight was similar between the groups (TXA: 9.2% vs No-TXA: 10.1%; P = .40). The number needed to treat (NNT) with TXA to avoid one peri-operative blood transfusion in this series was 9.The use of intraoperative TXA in patients with CP undergoing VDRO surgery lowers overall and postoperative transfusion rates.Level of evidence: III, Retrospective Comparative Study.

J Transl Med 2021; 19:116. [PMID: 33743699 PMCID: PMC7981850 DOI: 10.1186/s12967-021-02783-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Accepted: 03/09/2021] [Indexed: 11/10/2022] Open
Abstract
Background The ability to approximate intra-operative hemoglobin loss with reasonable precision and linearity is prerequisite for determination of a relevant surgical outcome parameter: This information enables comparison of surgical procedures between different techniques, surgeons or hospitals, and supports anticipation of transfusion needs. Different formulas have been proposed, but none of them were validated for accuracy, precision and linearity against a cohort with precisely measured hemoglobin loss and, possibly for that reason, neither has established itself as gold standard. We sought to identify the minimal dataset needed to generate reasonably precise and accurate hemoglobin loss prediction tools and to derive and validate an estimation formula. Methods Routinely available clinical and laboratory data from a cohort of 401 healthy individuals with controlled hemoglobin loss between 29 and 233 g were extracted from medical charts. Supervised learning algorithms were applied to identify a minimal data set and to generate and validate a formula for calculation of hemoglobin loss. Results Of the classical supervised learning algorithms applied, the linear and Ridge regression models performed at least as well as the more complex models. Most straightforward to analyze and check for robustness, we proceeded with linear regression. Weight, height, sex and hemoglobin concentration before and on the morning after the intervention were sufficient to generate a formula for estimation of hemoglobin loss. The resulting model yields an outstanding R2 of 53.2% with similar precision throughout the entire range of volumes or donor sizes, thereby meaningfully outperforming previously proposed medical models. Conclusions The resulting formula will allow objective benchmarking of surgical blood loss, enabling informed decision making as to the need for pre-operative type-and-cross only vs. reservation of packed red cell units, depending on a patient’s anemia tolerance, and thus contributing to resource management.

Estimation of blood volume and blood loss in primary total hip and knee replacement: An analysis of formulae for perioperative calculations and their ability to predict length of stay and blood transfusion requirements. J Orthop 2021; 24:227-232. [PMID: 33814813 DOI: 10.1016/j.jor.2021.03.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Revised: 01/27/2021] [Accepted: 03/07/2021] [Indexed: 01/28/2023] Open
Abstract
Introduction Blood loss continues to be a common surgical risk in total hip (THR) and knee replacements (TKR). Accurate prediction of blood loss permits appropriate counselling of risks to patients, target optimisation and forecasting future transfusion requirements. We compared blood volume formulae of Moore and Nadler, and blood loss formulae of Liu, Mercuriali, Bourke, Ward, Gross, Lisander and Meunier, to assess associations between calculated values with length of stay and transfusion requirements and determine which are useful in contemporary practice. Methods We retrospectively studied patients undergoing primary THR and TKR. We collected data on patient demographics, surgical interventions, pre- and postoperative haemoglobin and haematocrit values, length of stay and blood transfusion requirements. Spearman correlation tests and least squares multiple linear regression were performed. Results 149 THRs and 90 TKRs in 239 patients were analysed over four months. There was a very strong correlation between blood volume formulae. There were multiple very strong and strong associations between blood loss formulae. Bourke correlated significantly to length of stay, and Liu, Mercuriali, Lisander and Meunier correlated for incidence of transfusion. Conclusion Accurate estimation of perioperative blood loss is increasingly important as demand for joint replacement surgery increases in an ageing population. If the primary interest is the association of blood loss and length of stay, Bourke's formula should be preferred. If the primary interest is calculating risk of transfusion, the formulae of Liu or Meunier should be preferred. The formulae of Mercuriali and Lisander are becoming redundant in contemporary practice.

No Major Functional Benefit After Bicompartmental Knee Arthroplasty Compared to Total Knee Arthroplasty at 5-Year Follow-Up. J Arthroplasty 2020; 35:3587-3593. [PMID: 32739080 DOI: 10.1016/j.arth.2020.07.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 06/23/2020] [Accepted: 07/02/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND In case of isolated medial and patellofemoral joint arthritis, bicompartmental knee arthroplasty (BCA) is an alternative to total knee arthroplasty (TKA). The purpose of our prospective, randomized study is to compare the clinical outcome of BCA vs TKA. METHODS Eighty patients with isolated medial and patellofemoral osteoarthritis were randomly assigned to either BCA or TKA. Patients were evaluated preoperatively, 3, 6, and 12 months, and 2 and 5 years after the procedure. Knee Society Score, Oxford Knee Score, and the University of California,Los Angeles activity scores were calculated at each follow-up; Forgotten Joint Score was assessed at final follow-up. RESULTS There was an improvement in Knee Society Score, Oxford Knee Score, and the University of California,Los Angeles scores in both groups but no significant differences between both groups at any follow-up. The Forgotten Joint Score at 5-year follow-up was not significantly different either. Range of motion was significantly greater in the BCA group from 1-year follow-up onward. CONCLUSION Our study did not show significant differences in clinical scores between BCA and TKA; only range of motion was significantly greater in BCA. Therefore, it is questionable whether this difference justifies the complexity of BCA associated with higher risk of failure. Maybe staged patellofemoral joint arthroplasty in the presence of a well-functioning UKA is an option for BCA and an alternative to revision to TKA. Long-term studies are needed to explore the potential benefits of BCA.

Abstract
Background: Insufficient data are available to support the routine use of tranexamic acid
(TXA) in anterior cruciate ligament (ACL) surgeries with respect to
administration method and frequency, exposure duration, dose, and adverse
effects. Purpose: To investigate whether intra-articular (IA) administration of TXA could
reduce hemarthrosis and postoperative pain in patients after ACL
reconstruction. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 47 patients were included in this study, which was performed
between July 2017 and May 2019. Single-bundle reconstructions using
autologous hamstring tendon grafts were performed in all patients. The
patients were randomized into 2 groups: the TXA group (received the index
procedure with 100-mL IA injection of TXA [30 mg/mL]) and a control group
(did not receive IA injection of TXA). No patients received a drain. Blood
loss was calculated on the basis of hemoglobin balance at postoperative day
(PD) 2. The visual analog scale (VAS) for pain score was assessed at PD 3.
The midpatellar circumference was measured at PD 2 and PD 5. Knee range of
motion (ROM) was evaluated 6 weeks after surgery. Results: The mean ± SD blood loss was 467 ± 242 mL in the TXA group and 558 ± 236 mL
in the control group. No significant differences were found for blood loss
(P = .20), VAS pain scores (P = .28),
ROM at postoperative week 6 (P = .61), or patellar
circumference at PD 2 (P = .75) and PD 5
(P = .84). Conclusion: This study showed that IA administration of 3.0 g of TXA had no effect in
reducing blood loss and postoperative pain after primary anatomic
single-bundle ACL reconstruction using quadruple hamstring autografts. Registration: NCT04042688 (ClinicalTrials.gov
identifier).

Abstract
INTRODUCTION Endoprosthetic reconstruction presents a significant risk of perioperative blood loss. Tranexamic acid (TXA) is an antifibrinolytic agent used to reduce blood loss in orthopaedic procedures. The safety and efficacy of TXA in arthroplasty are well documented. There is, however, a dearth of literature exploring the safety and efficacy of TXA in musculoskeletal oncology patients. This retrospective, comparative study explores the effects of TXA on perioperative blood loss, blood transfusion rates, venous thromboembolism (VTE) occurrence, and hospital stay in patients undergoing resection of an aggressive bone tumor and endoprosthetic reconstruction. METHODS For the study, charts from a total of 90 patients who underwent resection of an aggressive bone tumor and endoprosthetic reconstruction were reviewed; of these patients, 34 were in the TXA group and 56 in the non-TXA group. Study participants composed of a heterogeneous group of patients with primary bone sarcoma and metastatic osseous disease. Patients in the TXA group received 1 g of topical TXA administered into the wound bed before closure. The Hemoglobin Balance method was used to calculate blood loss. Patients were followed for 6 weeks. RESULTS Patients undergoing proximal femur replacement and distal femur replacement in the TXA group experienced a 796 and 687 mL reduction in 72-hour mean blood loss, respectively (P = 0.0003 and P = 0.006). Average blood transfusions decreased by 0.45 U of packed red blood cells per patient in the TXA group (P = 0.048) and transfusion incidence decreased by 21.1% compared with the non-TXA group (P = 0.04). Patients undergoing proximal femur replacement in the TXA group left the hospital 2.2 days earlier than those in the non-TXA group (P = 0.0004). No increase in VTE rate was observed with TXA use. DISCUSSION This study found results similar to total joint arthroplasty with regard to TXA's effect on perioperative blood loss, transfusion rates, hospital stay, and VTE occurrence. It provides initial data to support the efficacy of topical TXA use in this patient cohort. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
Background Pain and blood loss after total knee arthroplasty (TKA) are unsolved clinical problems. Some studies reported that periarticular cocktail injection can effectively reduce pain and blood loss. However, there was no gold standard about the cocktail ingredient and injection location. More osteotomy and less soft tissue release in TKA with mild deformity; besides, plenty of nerves and blood vessels are contained in the periosteums and bone marrow. In this study, we aimed to detect the clinical results of subperiosteal cocktail application in TKA. Methods Two groups were included according to the different injection location in our study. In group 1, cocktails were injected into the muscles, tendons, suprapatellar bursa, and subpatellar bursa surrounding knee joint. In group 2, cocktail injection was performed under the periosteum of the distal femur and proximal tibia. Our primary outcomes were visual analogue scale (VAS) and hemoglobin (Hb), and the secondary outcomes were wound healing, infection, deep vein thrombosis (DVT), operation time, and hospitalization. Results At the first operative day, the mean (standard deviation) VAS score in a state of static was lower in group 2 compared with group 1 (0.98 ± 0.27 in group 1 and 0.86 ± 0.60 in group 2, p < 0.05). In the state of flexion and extension, the mean (standard deviation) VAS was 1.61 ± 0.66 in group 1 and 1.10 ± 0.57 in group 2 (p < 0.05). The mean (standard deviation) blood loss was higher in group 1 than in group 2 at the first postoperative day (440.19 (167.68) ml in group 1 and 333.67 (205.99) ml in group 2, p < 0.05). At the third day after surgery, the mean (standard deviation) blood loss was 686.44 (140.29) ml in group 1 and 609.19 (260.30) ml in group 2, and there was significant difference between these two groups (p < 0.05). Conclusions We concluded that subperiosteal cocktail injection can significantly reduce pain and blood loss compared with periarticular cocktail injection after TKA.

Intra-articular 1 g tranexamic acid administration during total knee arthroplasty is safe and effective for the reduction of blood loss and blood transfusion. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2019; 29:1737-1741.

Abstract
INTRODUCTION The effect of tranexamic acid (TXA) on the incidence of venous thromboembolic events (VTEs) in total knee arthroplasty (TKA) as assessed by contrast-enhanced computed tomography (CT) is unclear. Thus, we investigated the efficacy and safety profiles of TXA administration during TKA. We hypothesised that intra-articular 1 g TXA administration would have a sufficient effect on the reduction of blood loss and transfusion rates without increasing VTE risk. MATERIALS AND METHODS We retrospectively analysed 86 patients who underwent primary TKA from January 2014 to September 2017. The study comprised control (n = 45) and TXA (n = 41) groups. All patients underwent navigation-assisted TKA via the medial parapatellar approach. In those who received TXA, 1 g of intra-articular TXA was injected via a drain immediately following wound closure. The drain was clamped for 2 h and then reopened. Contrast-enhanced CT was performed 5-6 days after surgery to detect deep venous thrombosis (DVT) and pulmonary embolism (PE). Blood loss was calculated using the haemoglobin balance method. RESULTS The mean postoperative volume of blood loss was 900 ± 296 mL vs 1216 ± 445 mL in the TXA vs control group (p < 0.01). Allogeneic blood transfusion was required for 0 (0%) vs 6 (13.3%) patients in the TXA vs control group (p = 0.013). There were no significant inter-group differences regarding DVT and PE incidence (p > 0.05). No case of symptomatic PE occurred. CONCLUSIONS This study demonstrated that intra-articular 1 g TXA administration during TKA is safe and effective for reducing blood loss and blood transfusion without increasing VTE risk.

Tourniquet application does not affect the periprosthetic bone cement penetration in total knee arthroplasty. Knee Surg Sports Traumatol Arthrosc 2019; 27:2071-2081. [PMID: 30539303 DOI: 10.1007/s00167-018-5330-7] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2018] [Accepted: 12/07/2018] [Indexed: 12/28/2022]
Abstract
PURPOSE Poor scientific evidence exists on the issue of tourniquet application during total knee arthroplasty (TKA). It has been suggested that tourniquet application might improve interdigitation of the cement into the periprosthetic bones due to relatively dry surgical field. The hypothesis of the present study was that tourniquet use did not affect the periprosthetic bone cement penetration. METHODS The single-centre, randomized, controlled trial included 86 patients undergoing primary TKA (Clinical-Trials.gov NCT02475603). All patients meeting the inclusion criteria were randomly assigned to the tourniquet (n = 43) or non-tourniquet (n = 43) group after obtaining a written informed consent. The cumulative bone cement penetration was radiologically measured in AP (seven zones) and lateral views (three zones) as defined by Knee Society Scoring System. Further parameters such as perioperative blood loss, soft tissue swelling, pain level/analgesic consumption, operative time, length of hospital stay (LOS) and complication rate were statistically compared between the groups. RESULTS The cumulative bone cement penetration averaged 28.5 ± 1.7 mm in tourniquet versus 26.6 ± 1.6 mm in non-tourniquet groups (n.s.). The mean intraoperative blood loss was 250 ml higher in the non-tourniquet group (p = 0.0001). Patient-reported pre- to 6th-day post-operative reduction of the pain level was significantly higher in the non-tourniquet group (p = 0.003). The Morphine Equivalent Dose was higher in the Tourniquet group at discharge day (p = 0.02). Parameters such as total blood loss, soft tissue swelling, surgical time, LOS, and complication rates revealed similar results between the groups. CONCLUSIONS Tourniquet application did not influence the bone cement penetration significantly. Even though the intraoperative blood loss was reduced, the total blood loss was not affected significantly by tourniquet use. There was a tendency of higher post-operative pain and opioid analgesic requirement in the tourniquet group. LEVEL OF EVIDENCE I.

Abstract
Background Postoperative suction drains are used after total knee arthroplasty to avoid intra-articular hematoma formation although they can increase blood loss due to a negative suction effect. The use of tranexamic acid to reduce blood loss may nullify this. The aim of this study was to compare outcomes in patients undergoing total knee arthroplasty with or without drains and to analyze whether the drain's diameter also has an impact. Methods This is a prospective randomized study of patients undergoing unilateral total knee arthroplasty performed by a single surgeon. The study population was divided into three groups (A, 10G drain; B, 12G drain; and C, no drain). Pain, blood loss, swelling, wound-related complications, functional outcomes and questionnaire-based outcomes were assessed postoperatively. Results Each group had 35 patients comparable in most demographic and pre- and intraoperative characteristics. During the first 6 hours postoperatively, opioid consumption was significantly higher when the drain was not used (p = 0.036). At 3 months postoperatively, new Knee Society Score (NKSS) was highest with the use of 12G drain (p = 0.018). However, NKSS at 1 year was comparable across the three groups. With the use of tranexamic acid, blood loss and incidence of soakage of dressing were unaffected by the presence or absence of a drain. The calf girth, suprapatellar girth, soakage of dressing and range of motion were comparable in all three groups. There was no incidence of surgical site infection or deep vein thrombosis. Conclusions Presence of a suction drain significantly reduces opioid consumption during the first 6 hours after total knee arthroplasty. Use of a drain made no difference to the functional outcome at 1 year postoperatively. With the use of tranexamic acid in total knee arthroplasty, the total blood loss and the requirement of blood transfusion were unaffected by the presence or absence of closed suction drainage or by the bore of the drain used. The clinical parameters such as swelling, range of motion, infection and deep vein thrombosis also remained the same.

Abstract
BACKGROUND Postoperative anemia is a common complication after total hip arthroplasty (THA). However, the effect of edoxaban on postoperative anemia after THA remains unclear. Here, we retrospectively evaluated the clinical assessment of postoperative anemia and the associated changes of coagulation parameters in patients undergoing thromboprophylaxis with edoxaban compared with fondaparinux as a conventional anticoagulant thromboprophylactic agent after THA. METHODS One hundred and forty-nine patients who underwent THA from July 2010 to June 2012 were divided into two groups, according to whether they were operated on before or after the approval of edoxaban: the fondaparinux group (Group F: 86 patients) and the edoxaban group (Group E: 63 patients). The frequency of postoperative anemia and blood coagulation values were investigated. RESULTS Postoperative anemia developed more frequently in Group E than in Group F after surgery. However, the degree of postoperative anemia showed no significant difference between the groups. Meanwhile, prothrombin time (PT), prothrombin time-international normalized ratio (PT-INR), and activated partial thromboplastin time were markedly higher in patients with edoxaban-associated postoperative anemia, which showed an increased potential to predict the occurrence of postoperative anemia. Additionally, both PT and PT-INR in Group E were also correlated with the volume of estimated blood loss. CONCLUSION The frequency of postoperative anemia was increased in patients treated with edoxaban, compared to fondaparinux, after THA. Edoxaban thromboprophylaxis might, therefore, require more careful monitoring to prevent postoperative anemia. Additionally, particular prolongation of PT and PT-INR induced by edoxaban treatment might predict postoperative anemia.

Abstract
INTRODUCTION Anaemia in patients with trochanteric fracture is associated with increased morbidity and mortality and it is an independent risk factor for functional mobility of patients. Several authors have reported the blood loss following operative treatment comparing different fixation systems but few authors have evaluated many associated variables that could influence the perioperative blood loss. PURPOSE To evaluate the blood loss in patients that had their trochanteric fracture stabilized with dynamic hip screw (DHS) or Gamma nail. Multivariate analysis of different variables that can influence blood loss was carried out (type of fracture, antiaggregant or anticoagulant therapy, time to surgery). The hypothesis was that there is no difference in terms of blood loss in patients with trochanteric fracture treated with DHS or Gamma nail considering all these variables. MATERIALS & METHODS Perioperative blood loss was evaluated in 417 consecutive patients treated for trochanteric fracture with DHS or Gamma nail between January 2010 and March 2013. The perioperative blood loss was calculated using the Lisander formula modified by Foss-Kehlet based on pre- and post-operative haemoglobin values and transfusion rates. Univariate and multivariate analysis were performed integrating the following variables: type of fracture (A1 vs A2), antiaggregant/anticoagulant therapy vs no therapy, time to surgery (<24 vs >24 hours from trauma), type of implant (DHS vs Gamma nail). RESULTS A significant blood loss (p <0.05) was observed between A1 and A2 fracture types (1247ml vs 1796.7ml), antiaggregant/anticoagulant therapy and no therapy (1592.7ml vs 1470.2ml), time-to-surgery <24 and >24 hours from trauma (1584.4ml vs 1323.9ml), DHS and Gamma nail (894.7ml vs 1720.6ml). At multivariate analysis, in the A1 fracture groups the DHS showed a significant lower blood loss compared to Gamma nail (p < 0.05). CONCLUSIONS According to the perioperative blood loss, DHS should be used in A1 fractures while Gamma nail can be taking in account for the unstable A2 fractures.

Abstract
BACKGROUND Currently, various calculation methods for evaluating blood-loss in patients with total knee arthroplasty (TKA) are applied in clinical practice. However, different methods may yield different results. The purpose of this study was to determine the most reliable method for calculating blood-loss after primary TKA. METHODS We compared blood-loss in 245 patients who underwent primary unilateral TKA from February 2010 to August 2011. We calculated blood-loss using four methods: Gross equation, hemoglobin (Hb) balance, the Orthopedic Surgery Transfusion Hemoglobin European Overview (OSTHEO) formula, and Hb-dilution. We determined Pearson's correlation coefficients for the four methods. RESULTS There were large differences in the calculated blood-loss obtained by the four methods. In descending order of combined correlation coefficient based on calculated blood-loss, the methods were Hb-balance, OSTHEO formula, Hb-dilution, and Gross equation. CONCLUSIONS The Hb-balance method may be the most reliable method of estimating blood-loss after TKA.

Abstract
Total hip arthroplasty (THA) is an effective treatment for end-stage haemophilic arthropathy, and substitution therapy plays a key role in the success of THA. The aim of this study was to evaluate the efficacy of a modified coagulation factor substitution regime in THA. Nineteen haemophiliac patients (20 hips) who received primary cementless THA were enrolled. Based on World Federation of Haemophilia (WFH) guideline, a modified coagulation factor substitution regime was adopted. Blood loss, implant survival rates and complications were reviewed, retrospectively. The mean age at surgery was 29.7 years (15-49 years) and the mean follow-up period was 91 months (43-151 months). Mean total blood loss, external blood loss and hidden blood loss were 3543 (1494-7576), 1435 (600-3440), and 2110 ml (534-4402), respectively. Mean intraoperative blood loss and postoperative drainage were 715 (300-2000) and 713 ml (200-2950), respectively. Mean red blood cell transfusion used was 5 U (0-14). All prostheses were found to have bony ingrowth. One patient had hematoma formation in the thigh and one with a lower limb deep vein thrombosis, postoperatively. Other complications included one skin ulcer, one femur splitting fracture, and one transient neuropraxia. Intraoperative blood loss and wound drainage, in our study, were similar to that in haemophiliac patients and nonhaemophilic patients in literature. This supports the efficacy of the modified coagulation factor substitution strategy in our study.

Abstract
OBJECTIVE Non-selective NSAIDs can cause serious gastrointestinal side-effects. Selective COX-2 blockers are a reasonable alternative for pain treatment. They do not seem to affect platelet function and consequently cause a lower perioperative blood loss than non-selective NSAIDs. This study compared etoricoxib and diclofenac during a perioperative (9 days) period after THA to investigate total blood loss and gastrointestinal tolerability. The hypothesis was that etoricoxib is superior to diclofenac. METHODS A total of 100 patients (50 in each group) were included in this trial. Etoricoxib (90 mg) was administered once and diclofenac sodium (75 mg) twice daily for 9 days. Total blood loss during and after primary cementless THA was detected. The rate of adverse events (AEs) and serious adverse events (SAEs) was analyzed to detect gastrointestinal tolerability. RESULTS The mean total blood loss (calculated) was 1548 ± SD 468 ml in the etoricoxib (ETO) group and 1649 (SD 547) ml in the diclofenac (DIC) group. The mean duration of THA was 81 min (SD 29) in the DIC and 75 min (SD 30) in the ETO group. Hence, the mean calculated total blood loss was 101 ml higher in the DIC group. This difference was not statistically significant (p = 0.334). Fifty-six patients (28 in each group) received a cell saver retransfusion, but only one patient (ETO group) needed an additional red blood cell transfusion. The hidden blood loss was 1067 ml (SD 603) in the DIC group and 999 ml (SD 378) in the ETO group. The gastrointestinal tolerability (number of adverse and serious adverse events) was not significantly different between groups. CONCLUSION There was no statistically significant difference in perioperative blood loss after primary THA under etoricoxib (90 mg) compared to diclofenac (75 mg). Furthermore, no gastrointestinal superiority of etoricoxib could be detected during a short period of 9 days.

Abstract
BACKGROUND Despite the proven efficacy of both intravenous (IV) and intra-articular (IA) tranexamic acid (TXA) in reducing blood loss during total knee arthroplasty (TKA), the ideal route of administration remained debatable. This study aimed to compare the effect of IV versus IA TXA on transfusion incidences, perioperative blood loss and postoperative lower limb swelling during TKA. METHODS One hundred patients were prospectively randomised into two groups: 1) IV TXA; and 2) IA TXA. In both groups, TXA was administered intraoperatively after cementing the prostheses. The perioperative blood loss was calculated using the haemoglobin balance method. The thigh, suprapatellar, and calf girths were measured preoperatively and on postoperative day (POD) 4. RESULTS Two patients in the IV group and one patient in the IA group required blood transfusion (p=0.500). The median and interquartile range (IQR) of perioperative blood loss on POD1 and POD4 was 530 (IQR 386,704) and 730 (IQR 523,925) ml for the IV group, compared with 613 (IQR 506,703) and 799 (IQR 563,1067) ml for the IA group (p=0.090 and p=0.232 respectively). The median increment in thigh, suprapatellar, and calf girths were 1.5 (IQR 0, 3.0), 2.0 (IQR 0.5, 4.0) and 0 (IQR 0, 1.0) cm for the IV group, compared to 2.0 (IQR 1.0, 4.0), 2.0 (IQR 0, 4.5) and 0 (IQR 0, 1.5) cm for the IA group (p=0.246, p=0.562, and p=0.937 respectively). CONCLUSIONS Both IV and IA TXA had comparable effect on transfusion incidences, perioperative blood loss, and postoperative lower limb swelling during TKA. IA TXA is an alternative to IV TXA.

Abstract
BACKGROUND A significant proportion of patients with knee osteoarthritis have articular degeneration that is limited to the medial and patellofemoral compartments. The objective of this study was to compare clinical outcomes of unlinked bicompartmental knee arthroplasty (BCA) and total knee arthroplasty (TKA) at 5years in this subset of patients. METHODS 48 patients were randomised into two groups: unlinked, modular bicompartmental arthroplasty and total knee arthroplasty. Data on demographics and clinical outcomes were collected (Bartlett Knee Score, Oxford Knee Score, Knee Society Score). Data on intra-operative blood loss in both groups were also recorded. RESULTS Out of the 48 patients, 26 underwent BCA and 22 had TKA. Both groups shared similar demographic profiles. At five years post surgery, there was significant improvement across all functional scores in both groups. However, there was no significant difference in outcome scores in the BCA group compared to the TKA group. The drop in serum haemoglobin levels postoperatively was 1.55 and 2.30g/dl for the BCA and TKA groups respectively (p<.001). The total amount of blood loss was 397 and 647ml respectively (p=.001). CONCLUSIONS Unlinked, modular BCA results in similar clinical and functional scores as TKA for medial and patellofemoral arthritis in the mid-term. Intra-operative blood loss was significantly lower in the BCA group compared to the TKA group. BCA is a viable option for a select group of young and active patients with the advantage of reduced intra-operative blood loss and equivalent functional outcomes as TKA.

Abstract
PURPOSE To evaluate the effectiveness of intraarticular tranexamic acid (TXA) in reducing blood loss and the need for blood transfusion during total hip arthroplasty (THA). METHODS Records of 19 men and 31 women aged 46 to 83 (mean, 62) years who underwent primary THA with intra-articular administration of TXA were reviewed. They were compared with a matched cohort of 17 men and 33 women aged 40 to 87 (mean, 62) years who underwent the same procedure by the same surgeon without use of TXA. Postoperatively, a standard thromboembolic prophylaxis protocol was followed. A serum haemoglobin level of <80 g/l was the trigger for blood transfusion. RESULTS The 2 groups were comparable in terms of age, gender, body mass index, side involved, and anaesthesia method. No patient developed infection, wound haematoma, symptomatic deep vein thrombosis, or pulmonary embolism within 30 days. Compared with controls, patients in the TXA group had a higher median postoperative serum haemoglobin level (103 vs. 112 g/l, p=0.013), lower median drop in serum haemoglobin level (31 vs. 20 g/l, p<0.001), lower median total blood loss (900 vs. 575 ml, p<0.001), and lower transfusion rate (32% vs. 10%, p=0.007). The TXA treatment cost S$19.50 per patient, whereas one unit of allogenic blood cost S$123 per patient. Respectively in the control and TXA groups, the mean cost per patient was S$39.36 and S$31.80, indicating a 19% difference. CONCLUSION Intra-articular administration of TXA is a cost-effective and safe means to reduce blood loss and the need for blood transfusion during THA, without increasing the risk of thromboembolic events.

Abstract
PURPOSE Intraoperation autologous blood transfusion is an effective method that is used in surgeries with an important blood loss. Several studies suggest that massive blood transfusion is one of the independent risks for postoperative cognitive dysfunction (POCD). Whether the autologous blood is one of the risk factor for POCD or not, we retrospectively examined the incidence of POCD and the probable risk factors in patients undergoing lumbar surgery in our hospital, with the same aged non-POCD patients as controls. METHODS Eighty-one patients who underwent lumbar surgery were included. Perioperative data were examined for association with POCD on the 7 postoperative days by a Mini-Mental State Test. Multivariable logistic regression analysis was conducted to determine the probable risks associated with POCD. RESULTS POCD was found in 21 patients. Participants who developed POCD were more likely to had a lower eduction level, more likely to had more blood loss, higher incidence of preoperative anemia, and perioperative allogeneic blood transfusion of more than 3 units as independent risk factors for POCD 7 d postoperatively (P < 0.05). Otherwise, there is no significant difference of the patients received autologous blood or not (P > 0.05). CONCLUSION Autologous blood transfusion is not a risk factor for POCD in aged patients following lumbar surgery. Autologous blood is likely to be a better method of intraoperative blood transfusion during lumbar spine surgery.

Abstract
INTRODUCTION The use of tourniquet in total knee arthroplasty (TKA) has resulted in negligible intra-operative blood loss but notable post-operative blood loss, creating the ideal scenario for using topical haemostatic agents intra-operatively. Recently, medical adjuvants including tranexamic acid (TXA) and hydrogen peroxide (H2O2) have been introduced. The aim of this study was to evaluate the effectiveness of intra-articular TXA and H2O2 in reducing blood loss during TKA. MATERIALS AND METHODS Fifty patients, who underwent a primary TKA with 1,500 mg of intra-articular TXA between May 2011 and December 2011, were compared with two matching cohorts of 50 patients each who underwent TKA with 100 ml of 3 % H2O2 wash and TKA without any TXA or H2O2. All surgeries were performed by two senior surgeons. The total blood loss was calculated by the hemoglobin balance method. RESULTS The pre-operative serum hemoglobin levels were 13.1 ± 1.3, 13.1 ± 1.3 and 13.0 ± 1.2 g/dl (p > 0.05); while the drop in serum hemoglobin levels post-operatively was 2.0 ± 0.7, 2.4 ± 0.9 and 2.7 ± 0.8 g/dl for the TXA, H2O2 and Control groups, respectively (p < 0.001). The total amount of blood loss was 596 ± 449, 710 ± 279 and 760 ± 228 ml, respectively (p = 0.046). There was no difference in the duration of surgery between the three groups (p > 0.05). CONCLUSIONS This study showed that intra-articular TXA reduced blood loss during TKA without significantly increasing the duration of surgery. We cannot justify H2O2 wash as an alternative to intra-articular TXA to reduce blood loss during TKA.

Abstract
With the population aging, total joint replacements which are an effective method to restore patient's mobility are an increasing necessity. However, such operations are known to entail serious blood loss, which may have dramatic consequences in patients with chronic diseases or when the prosthesis is revised, a situation where the blood loss is even higher. Therefore, formulas to better estimate the blood loss are available. These formulas may also be used for clinical studies to compare blood loss between different joint replacement techniques. The aim of this review is to provide a clear understanding of the formulas and to help physicians to further improve their blood loss estimation. Moreover, surgeons will then be able to choose the most accurate and user-friendly formula for more comparable data between clinical studies.

Abstract
BACKGROUND AND PURPOSE Although a tourniquet may reduce bleeding during total knee replacement (TKA), and thereby possibly improve fixation, it might also cause complications. Migration as measured by radiostereometric analysis (RSA) can predict future loosening. We investigated whether the use of a tourniquet influences prosthesis fixation measured with RSA. This has not been investigated previously to our knowledge. METHODS 50 patients with osteoarthritis of the knee were randomized to cemented TKA with or without tourniquet. RSA was performed postoperatively and at 6 months, 1 year, and 2 years. Pain during hospital stay was registered with a visual analog scale (VAS) and morphine consumption was measured. Overt bleeding and blood transfusions were registered, and total bleeding was estimated by the hemoglobin dilution method. Range of motion was measured up to 2 years. RESULTS RSA maximal total point motion (MTPM) differed by 0.01 mm (95% CI -0.13 to 0.15). Patients in the tourniquet group had less overt bleeding (317 mL vs. 615 mL), but the total bleeding estimated by hemoglobin dilution at day 4 was only slightly less (1,184 mL vs. 1,236 mL) with a mean difference of -54 mL (95% CI -256 to 152). Pain VAS measurements were lower in the non-tourniquet group (p = 0.01). There was no significant difference in morphine consumption. Range of motion was 11° more in the non-tourniquet group (p = 0.001 at 2 years). INTERPRETATION Tourniquet use did not improve fixation but it may cause more postoperative pain and less range of motion.

Abstract
BACKGROUND The antifibrinolytic tranexamic acid reduces surgical blood loss, but studies have not identified an optimal regimen. QUESTIONS/PURPOSES We studied different dosages, timings, and modes of administration to identify the most effective regimen of tranexamic acid in achieving maximum reduction of blood loss in TKA. METHODS We prospectively studied five regimens (four intravenous, one local; 40 patients each) with a control group (no tranexamic acid). The four intravenous (10-mg/kg dose) regimens included (1) intraoperative dose (IO) given before tourniquet deflation, (2) additional preoperative dose (POIO), (3) additional postoperative dose (IOPO), and (4) all three doses (POIOPO). The fifth regimen was a single local application (LA). Two independent parameters of drain loss and total blood loss, calculated by the hemoglobin balance method, were evaluated statistically. RESULTS Both parameters were reduced in all five regimens as against the control. A significant reduction in drain loss was seen in the POIO, IOPO, and POIOPO groups whereas total blood loss was significantly reduced in the POIO, POIOPO, and LA groups. The POIOPO group had the least drain loss (303 mL) and least total blood loss (688 mL). The IO group had the greatest drain loss and the IOPO group the greatest total blood loss. CONCLUSIONS Single-dose tranexamic acid did not give effective results. The two-dose regimen of POIO was the least amount necessary for effective results. When compared against the control, this regimen produced reduction of drain loss and total blood loss, whereas the IOPO regimen did not. The three-dose regimen of POIOPO produced maximum effective reduction of drain loss and total blood loss.

Abstract
The objective of this study was to report the perioperative safety and efficacy of single-stage, bilateral hip resurfacing arthroplasties (HRAs) in 104 patients. The mean preoperative ASA grade was 1.7 + 0.6, and the mean total operative time was 3 hours and 31 minutes (+ 32 mins). 13 patients (12.5%) required a homologous blood transfusion. Local complications included 5 patients with unilateral, serous, incisional drainage after postoperative day 3, with 1 patient (0.9%) requiring a superficial irrigation and debridement. One systemic complication (0.9%) was noted, as one patient developed atrial fibrillation. There were no episodes of femoral neck fracture, deep venous thrombosis, or pulmonary embolism, although routine screening for thromboembolic disease was not performed. Hospital length of stay averaged 4.1 + 0.9 days, with 76% of patients discharged home. A single-stage procedure carries an acceptable complication risk, requires a low rate of homologous blood transfusion, and has a low rate of local and systemic complications when performed in the appropriately selected patient.

Abstract
BACKGROUND Transurethral resection of the prostate (TURP) remains the gold standard in the operative management of symptomatic benign prostatic hyperplasia (BPH). The main morbidity of TURP is bleeding, which leads to clot retention and blood transfusion. Newer techniques have appeared, and photovaporization of the prostate (PVP) with the GreenLight™ laser has been developed to reduce the morbidity of bladder outflow surgery. Isotopic measurements of total red cell volume and total blood volume (BV) are a recommended reference technique to evaluate bleeding occurring during endoscopic ablation of the prostate. Here, we compare blood loss during PVP and TURP using an isotopic method. METHODS Eighteen patients underwent PVP, and 20 patients underwent a TURP for symptomatic BPH by one surgeon. The two groups were comparable in demographic data; however, prostate volume was significantly higher in the PVP group. BV was measured pre- and postoperatively using the isotope technique. RESULTS The total BV was measured to have increased by 362 mL in PVP group compared with a loss of 315 mL in TURP group (p=0.001). The difference in total red cell volume increased by 148 mL in PVP group compared with a loss of 216 mL in TURP group (p=0.005). CONCLUSIONS Using the isotope method, we have shown a significant difference in postoperative blood loss between TURP and PVP. Our study is the first to use an isotopic method to measure the blood loss during PVP. This technique needs further standardization before being introduced into routine clinical practice.

Abstract
BACKGROUND Adhesions formation is a significant postsurgical complication. At present, there is no effective method for preventing adhesions formation 1, although barrier products such as Dextran (Dex) 2 and sodium hyaluronate (SH) 3 have proved the most clinically successful 456, This study is designed to investigate the preventive and therapeutic potential of a novel penicillamine-bound membrane for abdominal adhesions formation. METHODS 150 rats were involved in the present study. All animals were randomly divided into 6 groups (1 vehicle group and 5 test groups respectively treated with dextran, sodium hyaluronate, penicillamine, penicillamine-bound membrane or non-penicillamine-bound membrane). The occurrence, grade and score of abdominal adhesions were compared between the different groups. The breaking strength of incision was compared between the vehicle group and the penicillamine, membrane with/without penicillamine - treated groups. Expression of collagen type I was compared between the vehicle and penicillamine-treated group. The occurrence of adhesions was compared between the Dextran (Dex), sodium hyaluronate (SH), penicillamine-treated group and membrane with or without penicillamine- treated groups. RESULTS Penicillamine and penicillamine-bound membrane had significant preventive effects on abdominal adhesions formation, better than dextran, sodium hyaluronate and non-penicillamine-bound membrane. However, neither of them influenced incision healing, although they insignificantly decreased the breaking strength of the incision. Penicillamine-bound membrane, which can be loaded locally and more efficaciously, shows greater advantages than penicillamine. CONCLUSIONS Penicillamine-bound membrane can be applied as an effective therapeutic intervention for abdominal adhesions with inconsequential side effects.

Abstract
PURPOSE The inflammatory response triggered by transfusion is implicated in the pathophysiology of transfusion-related immunomodulation. The authors hypothesized that two distinctive autotransfusion methods, acute normovolemic hemodilution (ANH) and preoperative donation (PD), have different influences on both inflammatory mediator generation during storage and the inflammatory response after a transfusion. The purpose of this study was to compare the plasma concentrations of neutrophil elastase (NE), interleukin (IL)-6, IL-8, and IL-10 in patients who underwent either of these two autologous transfusion methods. METHODS With institutional review board approval, the plasma concentrations of the above inflammatory mediators were determined in 23 patients with ANH and 8 patients with PD at the following time points: after anesthetic induction, at the end of the operation, and the morning of postoperative day 1. The concentrations of these inflammatory mediators were also measured in the donated blood obtained by either ANH or PD before retransfusion. RESULTS The mean storage durations were 3.7 h and 6.1 days for ANH and PD, respectively. Higher concentrations of NE and IL-10 were detected in the PD blood than in the ANH blood. Long duration of storage and/or low temperature may have been responsible for the increased NE and IL-10 concentrations in the PD blood. However, the difference between the two groups in the extent of increased plasma concentrations of these inflammatory mediators was not statistically significant. CONCLUSION Inflammatory mediators were significantly increased in PD blood during storage compared to the blood obtained by ANH. However, their effects on the inflammatory response elicited in the recipients were not significantly different.

Abstract
BACKGROUND Total hip replacement (THR) is associated with a significant perioperative blood loss, and 30-50% of these patients receive allogeneic blood transfusion (ABT). We evaluated the clinical utility of washed shed blood (WSB) return to reduce ABT in THR patients. STUDY DESIGN AND METHODS Data from 108 consecutive THR patients were prospectively collected. WSB salvage and reinfusion (OrthoPAT) was intended for 60 (Reinfusion group), whereas the remaining 48 patients served as control group. Patients received ABT if haemoglobin <8 g/dl or clinical signs and symptoms of acute anemia. RESULTS WSB return was possible in 49 patients (205 +/- 151 ml of erythrocyte/patient), without any clinically relevant incident. Return of WSB decreased both the ABT rate (48 vs. 15%, for control and reinfusion groups, respectively; P = 0.001) and the ABT index (371 +/- 154 ml RBC vs. 53 +/- 117 ml RBC, respectively; P = 0.001), without differences between cemented and uncemented THR. In addition, patients from reinfusion group showed a trend to lower postoperative infection rate (10 vs. 2%, respectively; P = 0.086). CONCLUSIONS Perioperative salvage and return of WSB in THR seems to effectively reduce the requirements for ABT. However, for patients with preoperative Hb < 13 g/dl, some additional blood saving method should be associated to WSB return.

Abstract
BACKGROUND AND OBJECTIVES Analysis of haemoglobin (Hb) dilution after bleeding is a simple, inexpensive and non-invasive method to estimate blood loss. Blood volume is estimated, taking sex, weight and height into account. The Hb concentration before and after blood loss is analysed and, from the difference, the blood loss volume can be calculated assuming a normovolemic subject. Although widely used this method has never been validated. MATERIAL AND METHODS The Hb concentration of 21 blood donors was analysed before and up to 4 days after a standard blood donation and in another 18 blood donors the Hb concentration was analysed before and on day 4, 6, 8, 11 and 14 after blood donation. The blood volume of each donor was calculated and the donated blood volume was estimated by weighing. We calculated the blood loss by the Hb dilution method and compared the calculated value with the donated blood volume. RESULTS The mean donated blood volume was 442 +/- 10 ml, whereas the mean calculated blood loss was 152 +/- 214 ml using the Hb concentration of the first day after donation and 301 +/- 145 ml with the Hb concentration of day 6 after blood donation after which no further Hb decrease was observed. The directly measured Hb concentration was always higher than the calculated/expected Hb concentration based on the blood donation volume. CONCLUSIONS The Hb dilution method underestimates the true blood loss by more than 30% after a moderate blood loss of approximately 10% of the total blood volume.

Abstract
STUDY DESIGN Review of the use of Cell Saver in a non-randomized group of patients undergoing spinal fusion for scoliosis. OBJECTIVES To determine the efficacy of the use of Cell Saver for spinal fusions for scoliosis. Although Cell Saver is widely used in scoliosis surgery, it is not clear whether its use decreases the need for other transfusions or whether there are certain patients more likely to benefit from its use. The blood collected by Cell Saver intraoperatively is not always of sufficient volume to be returned to the patient, and there are no current guidelines addressing the amount that is likely to be returned to the patient. PURPOSE The purpose of this study was to determine: Does use of Cell Saver reduce the need for other transfusions in scoliosis surgery? Is there an amount of blood loss at which Cell Saver is likely to be returned? MATERIALS AND METHODS The study group consisted of 95 children who had undergone posterior spinal fusion between January 2002 and March 2004 with one of two surgeons. One surgeon used Cell Saver, the other surgeon did not. Of the total, 58 patients who underwent posterior spinal fusion with the use of Cell Saver (group 1) were compared with the 37 (group 2) who underwent the same procedure without the use of Cell Saver. RESULTS Of those in group 1, 34 received Cell Saver blood back as an intraoperative autologous transfusion (IAT) (59%). Patients in the Cell Saver group were just as likely to receive non-Cell Saver transfusions as those in the control group (P = 0.12). Of the 39 patients who lost more than 500 cc of blood, 34 received IAT (87%). No patient who lost less than 500 cc of blood received IAT. CONCLUSION The use of Cell Saver does not reduce the need for other transfusions in scoliosis surgery. The amount of blood loss at which Cell Saver is likely to be returned is 500 cc. We demonstrated no benefit in the use of Cell Saver in our patient population.

Abstract
The routine use of surgical drains in total hip arthroplasty remains controversial. They have not been shown to decrease the rate of wound infection significantly and can provide a retrograde route for it. Their use does not reduce the size or incidence of post-operative wound haematomas. This prospective, randomised study was designed to evaluate the role of drains in routine total hip arthroplasty. We investigated 552 patients (577 hips) undergoing unilateral or bilateral total hip arthroplasty who had been randomised to either having a drain for 24 hours or not having a drain. All patients followed standardised pre-, intra-, and post-operative regimes and were independently assessed using the Harris hip score before operation and at six, 18 and 36 months follow-up. The rate of superficial and deep infection was 2.9% and 0.4%, respectively, in the drained group and 4.8% and 0.7%, respectively in the undrained group. One patient in the undrained group had a haematoma which did not require drainage or transfusion. The rate of transfusion after operation in the drained group was significantly higher than for undrained procedures (p < 0.042). The use of a drain did not influence the post-operative levels of haemoglobin, the revision rates, Harris hip scores, the length of hospital stay or the incidence of thromboembolism. We conclude that drains provide no clear advantage at total hip arthroplasty, represent an additional cost, and expose patients to a higher risk of transfusion.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is often carried out using a tourniquet and shed blood is collected in drains. Tranexamic acid decreases the external blood loss. Some blood loss may be concealed, and the overall effect of tranexamic acid on the haemoglobin (Hb) balance is not known. METHODS Patients with osteoarthrosis had unilateral cemented TKA using spinal anaesthesia. In a double-blind fashion, they received either placebo (n=24) or tranexamic acid 10 mg kg(-1) (n=27) i.v. just before tourniquet release and 3 h later. The decrease in circulating Hb on the fifth day after surgery, after correction for Hb transfused, was used to calculate the loss of Hb in grams. This value was then expressed as ml of blood loss. RESULTS The groups had similar characteristics. The median volume of drainage fluid after placebo was 845 (interquartile range 523-990) ml and after tranexamic acid was 385 (331-586) ml (P<0.001). Placebo patients received 2 (0-2) units and tranexamic acid patients 0 (0-0) units of packed red cells (P<0.001). The estimated blood loss was 1426 (1135-1977) ml and 1045 (792-1292) ml, respectively (P<0.001). The hidden loss of blood (calculated as loss minus drainage volume) was 618 (330-1347) ml and 524 (330-9620) ml, respectively (P=0.41). Two patients in each group developed deep vein thrombosis. CONCLUSIONS Tranexamic acid decreased total blood loss by nearly 30%, drainage volume by approximately 50% and drastically reduced transfusion. However, concealed loss was only marginally influenced by tranexamic acid and was at least as large as the drainage volume.

Abstract
There is evidence to suggest that there exists considerable variation in red blood cell (RBC) transfusion practices, especially in the surgical specialties. This is in large part related to difficulties in defining specific transfusion threshold criteria, given that there is no minimum acceptable hemoglobin threshold concentration and there is variability in assigning importance to patient factors. The purpose of this study is to identify patient-related factors that might be associated with the need for allogeneic RBC transfusion in surgical patients. We systematically identified, selected, and reviewed all observational or interventional studies describing patient-specific or related variables associated with the need for allogeneic RBC transfusion in the surgical patient population. We also evaluated the methodological characteristics of the individual studies. Sixty-two studies met our inclusion criteria and were analyzed for this review. Most of these studies were conducted in patients undergoing cardiac surgery (n = 30) and orthopedic surgery (n = 16). Decreased preoperative red cell reserve was most frequently associated with RBC transfusions, being identified as a significant variable in 46 studies. The other factors commonly associated with transfusion were advancing age (n = 28), female gender (n = 21), and small body size (n = 14). Only 2 studies attempted to prospectively validate a predictive model for RBC transfusion based on the variables identified. This systematic review shows that preoperative anemia, advancing age, female gender, and small body size are often associated with perioperative allogeneic RBC transfusion. However, the retrospective nature of most of the studies and the small sample sizes make it difficult to formulate a clinically useful prediction rules regarding allogeneic RBC transfusion. Ongoing research in designing large prospective cohort studies evaluating transfusion patterns are needed to further elucidate how patient characteristics impact the transfusion threshold.

Abstract
Better Blood Transfusion' (Department of Health (1998) HSC 1998/224) stressed the need for National Health Service Trusts to explore the feasibility of autologous blood transfusions and raise patient awareness of these techniques. The development of an appropriate strategy to promote autologous transfusion requires an understanding of current use, along with constraints to increasing practice. Past surveys have shown unchanging attitudes to autologous transfusion (Torrella et al. (2001) Transfusion Medicine, 11, 15-19), but detailed information regarding the extent of autologous transfusion in England and North Wales was not available. This survey, carried out in 2001, considered autologous transfusion under four headings: predeposit autologous donation, acute normovolaemic haemodilution, intra-operative cell salvage and postoperative cell salvage. Questionnaires were returned from 265/310 (85.4%) hospitals served by the National Blood Service. Sixty per cent of respondents performed at least one autologous technique, although practice was limited to a few clinicians within each hospital. Predeposit donation was the most widespread technique but involved very few patients. Intra- and postoperative cell salvage techniques were practised in fewer hospitals but on many more patients. The main constraints to increasing use of autologous techniques were perceived to be logistical, but removal of constraints may only result in small increases in individual practice. More clinicians need to be encouraged to utilize appropriate, evidence-based autologous techniques.

Abstract
Intraoperative autotransfusion salvages blood shed during surgery for use in immediate resuscitation of the patient. The purpose of this study was to determine whether such autotransfusion decreases the volume of homologous blood transfused in patients undergoing primary cranial vault remodeling for craniosynostosis. The Cobe-Bret 2 autologous blood recovery system (Hemo Concepts, Union, N.J.) was used in 11 cases, and an equal number of consecutive cases did not receive intraoperative autotransfusion. There were no significant differences between the groups with respect to age, sex, and weight. Mean estimated blood loss was 43.2 ml/kg (range, 20.3 to 65.0 ml/kg) in the intraoperative autotransfusion group and 40.2 ml/kg (range, 6.8 to 72.3 ml/kg) in the control group (not statistically significant; p < 0.05). There was no significant difference in volume of homologous blood transfusion between the two groups. The autotransfusion group received 34.1 ml/kg of homologous blood (range, 0 to 60.7 ml/kg), and the control group received a mean of 32.7 ml/kg (range, 14.5 to 60.2 ml/kg). The autotransfusion group received a mean of 10.4 ml/kg of recovered autologous blood (range, 0 to 21.4 ml/kg). In four of the 11 autotransfusion patients, insufficient autologous blood was recovered intraoperatively to warrant transfusion. Results of this study suggest little benefit for the use of intraoperative autotransfusion in primary cranial vault remodeling for craniosynostosis in the young patient. It was hypothesized that this finding was a result of the following: (1) intraoperative autotransfusion blood was usually available only toward the end of the procedure, after homologous blood had already been administered, and (2) the volume of recovered intraoperative autotransfusion blood is minimal, compared with the homologous transfusion volume requirements during an extensive cranial vault remodeling and fronto-orbital advancement procedure. In the context of unproven cost benefit and increasing similar evidence from other comparative studies, emphasis should be directed to other medical and surgical strategies to minimize the need for perioperative blood transfusion.

Abstract
We compared allogeneic blood usage for two groups of patients undergoing total knee replacement surgery (TKR). Patients were randomized to receive either their post-operative wound drainage as an autotransfusion (n=115) after processing or to have this wound drainage discarded (n=116). Allogeneic blood was transfused in patients of either group whose haemoglobin fell below 9 g dl(-1). Only 7% of patients in the autotransfusion group required an allogeneic transfusion compared with 28% in the control group (P<0.001). There was no hospital mortality and only 3% mortality from all causes at the study completion, which spanned 6 months to 3 yr. There was a higher incidence of infection requiring intervention in the allogeneic group (P<0.036). Total patient costs were Pound Sterling 113 greater in the autotransfusion group. We conclude that in this type of surgery post-operative cell salvage is a safe and effective method for reducing allogeneic blood use.
