Arch Orthop Trauma Surg 2023; 143:1311-1321. [PMID: 34854977 DOI: 10.1007/s00402-021-04278-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Accepted: 11/24/2021] [Indexed: 12/11/2022]
Abstract
PURPOSE The American Academy of Orthopaedic Surgeons does not currently provide clinical practice guidelines for management of PAF. Accordingly, this article aims to review and consolidate the relevant historical and recent literature in important topics pertaining to perioperative management of PAF. METHODS A thorough literature review using PubMed, Cochrane and Embase databases was performed to assess preoperative, intraoperative and postoperative management of PAF fracture. Topics reviewed included: time from injury to definitive fixation, the role of inferior vena cava filters (IVCF), tranexamic acid (TXA) use, intraopoperative cell salvage, incisional negative pressure wound therapy (NPWT), intraoperative antibiotic powder use, heterotopic ossification prophylaxis, and pre- and postoperative venous thromboembolism (VTE) prophylaxis. RESULTS A total of 126 articles pertaining to the preoperative, intraoperative and postoperative management of PAF were reviewed. Articles reviewed by topic include 13 articles pertaining to time to fixation, 23 on IVCF use, 14 on VTE prophylaxis, 20 on TXA use, 10 on cell salvage, 10 on iNPWT 14 on intraoperative antibiotic powder and 20 on HO prophylaxis. An additional eight articles were reviewed to describe background information. Five articles provided information for two or more treatment modalities and were therefore included in multiple categories when tabulating the number of articles reviewed per topic. CONCLUSION The literature supports the use of radiation therapy for HO prophylaxis, early (< 5 days from injury) surgical intervention and the routine use of intraoperative TXA. The literature does not support the routine use of iNPWT or IVCF. There is inadequate information to make a recommendation regarding the use of cell salvage and wound infiltration with antibiotic powder. While the routine use of chemical VTE prophylaxis is recommended, there is insufficient evidence to recommend the optimal agent and duration of therapy.

Abstract
BACKGROUND Severe trauma represents a major global public health burden and the management of post-traumatic bleeding continues to challenge healthcare systems around the world. Post-traumatic bleeding and associated traumatic coagulopathy remain leading causes of potentially preventable multiorgan failure and death if not diagnosed and managed in an appropriate and timely manner. This sixth edition of the European guideline on the management of major bleeding and coagulopathy following traumatic injury aims to advise clinicians who care for the bleeding trauma patient during the initial diagnostic and therapeutic phases of patient management. METHODS The pan-European, multidisciplinary Task Force for Advanced Bleeding Care in Trauma included representatives from six European professional societies and convened to assess and update the previous version of this guideline using a structured, evidence-based consensus approach. Structured literature searches covered the period since the last edition of the guideline, but considered evidence cited previously. The format of this edition has been adjusted to reflect the trend towards concise guideline documents that cite only the highest-quality studies and most relevant literature rather than attempting to provide a comprehensive literature review to accompany each recommendation. RESULTS This guideline comprises 39 clinical practice recommendations that follow an approximate temporal path for management of the bleeding trauma patient, with recommendations grouped behind key decision points. While approximately one-third of patients who have experienced severe trauma arrive in hospital in a coagulopathic state, a systematic diagnostic and therapeutic approach has been shown to reduce the number of preventable deaths attributable to traumatic injury. CONCLUSION A multidisciplinary approach and adherence to evidence-based guidelines are pillars of best practice in the management of severely injured trauma patients. Further improvement in outcomes will be achieved by optimising and standardising trauma care in line with the available evidence across Europe and beyond.

Cell Salvage in Oncological Surgery, Peripartum Haemorrhage and Trauma. SURGERIES 2022.

Abstract
Oncological surgery, obstetric haemorrhage and severe trauma are the most challenging conditions for establishing clinical recommendations for the use of cell salvage. When the likelihood of allogeneic transfusion is high, the intraoperative use of this blood-saving technique would be justified, but specific patient selection criteria are needed. The main concerns in the case of oncological surgery are the reinfusion of tumour cells, thereby increasing the risk of metastasis. This threat could be minimized, which may help to rationalize its indication. In severe peripartum haemorrhage, cell salvage has not proven cost-effective, damage control techniques have been developed, and, given the risk of fetomaternal alloimmunization and amniotic fluid embolism, it is increasingly out of use. In trauma, bleeding may originate from multiple sites, coagulopathy may develop, and it should be evaluated whether re-transfusion of autologous blood collected from uncontaminated organ cavities would be feasible. General safety measures include washing recovered blood and its passage through leukocyte depletion filters. To date, no well-defined indications for cell salvage have been established for these pathologies, but with accurate case selection and selective implementation, it could become safe and effective. Randomized clinical trials are urgently needed.

Abstract
BACKGROUND Acetabular fracture open reduction and internal fixation (ORIF) is generally associated with high intraoperative blood loss. Hypotensive anesthesia has been shown to decrease blood loss and intraoperative transfusion in total joint arthroplasty and posterior spinal fusion. In this study, we assessed the effect of reduction in intraoperative mean arterial pressures (MAPs) during acetabular fracture surgery on intraoperative blood loss and need for transfusion. METHODS Three hundred and one patients with acetabular fractures who underwent ORIF at an academic Level 1 trauma center were retrospectively reviewed. Patients were separated based on mean intraoperative MAPs (<60 mmHg, 60-70 mmHg, >70 mmHg). Thirteen patients had mean intraoperative MAP <60 mmHg, 95 had MAP 60-70 mmHg, and 193 had MAP >70 mmHg. Rates of intraoperative and postoperative allogeneic blood transfusion were compared. RESULTS Mean intraoperative MAPs were significantly different between groups (p < 0.0001). Time from injury to surgery, estimated blood loss, operative time and intraoperative IV fluids were comparable. The proportion of patients who received blood transfusion and mean units transfused intraoperatively and postoperatively were similar between groups. Mean differences in preoperative and postoperative hemoglobin and hematocrit were also similar. There was no difference in hospital length of stay or perioperative complications between the groups. Multivariate logistic regression analysis demonstrated that body mass index > 30 (p < 0.05) and anterior surgical approach (p < 0.01) were independently associated with intraoperative transfusion and an anterior surgical approach (p < 0.001) was independently associated with postoperative transfusion. CONCLUSION Decreased intraoperative MAP during acetabular fracture surgery does not reduce blood loss or need for transfusion. On the other hand, no increased end-organ ischemia was seen with hypotensive anesthesia. LEVEL OF EVIDENCE Therapeutic Level III.

INTERNATIONAL ORTHOPAEDICS 2021; 45:2727-2734. [PMID: 33585973 DOI: 10.1007/s00264-021-04970-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Accepted: 02/02/2021] [Indexed: 11/28/2022]
Abstract
PURPOSE This study aims to compare the effectiveness of anatomic locking plate and reconstruction plate used in treating acetabular fractures. METHODS From January 2009 to January 2016, patients with acetabular fractures were included in this retrospective study. We grouped the patients into two groups based on the internal fixation: reconstruction plate group (RPG) and anatomic locking plate group (ALPG). The operation time, blood loss, intra-operative screw penetration, and plate breakage were compared between the two groups. The intra-operative fluoroscopic images were used to evaluate the fixation location. The quality of reduction and radiological grading were assessed according to the criteria developed by Matta. The clinical assessment was based on the Merle d'Aubigne-Postel score. RESULTS Eighty-three patients were included in this study and were followed up for an average of 35 months (range, 25 to 42 months). Thirty-five patients were treated with the anatomical locking plate, and 48 patients were treated with the reconstruction plate. The mean surgical time was significantly shorter (P < 0.0001) in ALPG patients than in RPG patients, and the intra-operative blood loss was significantly lower (P = 0.008). The rates of intra-operative screw penetration or plate breakage in the ALPG (0/35) are significantly lower than that in the RPG (7/48) (P = 0.018). Post-operative Matta score (P = 0.905), Merle d'Aubigne-Postel score (P = 0.957), and overall complication rates (P = 0.391) were not significantly different among the groups. CONCLUSION Patients treated by anatomical locking plate had shorter operation time, less bleeding, and lower rate screw perforation compared to patients treated by reconstruction plate. Anatomical locking plate is a better choice for acetabulum fractures, especially complicated fractures.

Abstract
PURPOSE The primary objective was to identify the predictors of in-hospital mortality after pelvic ring injuries. Secondary objectives were to analyze the differences between adults and children and to analyze the causes and timing of death. METHODS A retrospective cohort study from the pelvic registry of Assiut University Trauma Unit (AUTU), a level 1 trauma centre in Upper Egypt, was carried out. A total of 1188 consecutive patients with pelvic ring fractures treated from January 2010 to December 2013 were eligible for analysis. Potential predictors were identified using standard statistical tests: univariable and multivariable regression analysis. RESULTS Nine hundred fifty-one were adults (above 16 years) and 237 were children. According to Tile's classification, fractures type A, B, and C were 31.8%, 25.1%, and 43.1%, respectively. About a third of patients had fractures with soft tissue injury. Abdominopelvic collection as diagnosed by Focused Assessment with Sonography for Trauma (FAST) was positive in 11%. Associated injuries were present in 67.3% with abdominal-urogenital injuries being the most prevalent (66.3%). Median hospital stay was five days. Fifty-two patients (4.4%) were admitted to the ICU. One hundred three patients died (8.7%) within two peaks: first 24 hours and between 48 hours and one week. Multivariable logistic regression analysis identified increasing age, fractures with soft tissue injury, associated head injury, positive FAST examination, and admission to an ICU as significant predictors of in-hospital mortality. CONCLUSIONS The first 24 hours were confirmed to be critical for survival in pelvic fracture patients. Advancing age, associated soft tissue injury, associated head injury, admission to ICU, and positive FAST examination can serve as reliable predictors for an elevated mortality risk in such patients.
