Randomised controlled trial of tourniquet associated pain generated in lower limb after exsanguination by Esmarch bandage versus limb elevation. J Orthop Surg Res 2024; 19:276. [PMID: 38698470 PMCID: PMC11067074 DOI: 10.1186/s13018-024-04749-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Accepted: 04/18/2024] [Indexed: 05/05/2024] Open
Abstract
BACKGROUND Tourniquets are common adjuncts in the operating theatre but can be associated with post-operative pain. This study was designed to compare what effect pre-tourniquet Esmarch bandage exsanguination has on pain, compared to pre-tourniquet exsanguination by elevation alone. METHODS 52 volunteers (104 lower limbs) were included in this study with each volunteer acting as their own matched control. The primary outcome was patient reported pain, measured in both legs simultaneously using area under curve. Secondary outcomes were pain score during inflation and deflation, cumulative pain score, duration of recovery and blood pressure during testing. RESULTS Pain after Esmarch was superior to elevation as measured by area under pain curve (68.9 SD 26.1 vs 77.2 SD 27.3, p = 0.0010), independent of leg dominance. Cumulative pain scores demonstrated the same superiority after inflation (50.7 SD 17.1 vs 52.9 SD 17.0, p = 0.026) but not after deflation (p = 0.59). Blood pressure was not significantly different. Time to full recovery of the lower limb was the same for both groups-7.6 min (SD 2.1 min, p = 0.80). CONCLUSION Previous studies describe a positive effect on pain when Esmarch bandage was used prior to tourniquet inflation for upper limb. Our findings suggest the same benefit from Esmarch when it was used on lower limbs-particularly during inflation of tourniquet. In addition to pain profiles, surgeon preference and patient factors need to be considered when deciding between elevation and Esmarch bandage.

Comparing outcomes in patients with exsanguinating injuries: an Eastern Association for the Surgery of Trauma (EAST), multicenter, international trial evaluating prioritization of circulation over intubation (CAB over ABC). World J Emerg Surg 2024; 19:15. [PMID: 38664763 PMCID: PMC11044388 DOI: 10.1186/s13017-024-00545-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Accepted: 04/21/2024] [Indexed: 04/28/2024] Open
Abstract
INTRODUCTION Hemorrhage is a major cause of preventable trauma deaths, and the ABC approach is widely used during the primary survey. We hypothesize that prioritizing circulation over intubation (CAB) can improve outcomes in patients with exsanguinating injuries. METHODS A prospective observational study involving international trauma centers was conducted. Patients with systolic blood pressure below 90 who were intubated within 30 min of arrival were included. Prioritizing circulation (CAB) was defined as delaying intubation until blood products were started, and/or bleeding control was performed before securing the airway. Demographics, clinical data, and outcomes were recorded. RESULTS The study included 278 eligible patients, with 61.5% falling within the "CAB" cohort and 38.5% in the "ABC" cohort. Demographic and disease characteristics, including age, sex, ISS, use of blood products, and other relevant factors, exhibited comparable distributions between the two cohorts. The CAB group had a higher proportion of penetrating injuries and more patients receiving intubation in the operating room. Notably, patients in the CAB group demonstrated higher GCS scores, lower SBP values before intubation but higher after intubation, and a significantly lower incidence of cardiac arrest and post-intubation hypotension. Key outcomes revealed significantly lower 24-hour mortality in the CAB group (11.1% vs. 69.2%), a lower rate of renal failure, and a higher rate of ARDS. Multivariable logistic regression models showed a 91% reduction in the odds of mortality within 24 h and an 89% reduction at 30 days for the CAB cohort compared to the ABC cohort. These findings suggest that prioritizing circulation before intubation is associated with improved outcomes in patients with exsanguinating injuries. CONCLUSION Post-intubation hypotension is observed to be correlated with worse outcomes. The consideration of prioritizing circulation over intubation in patients with exsanguinating injuries, allowing for resuscitation, or bleeding control, appears to be associated with potential improvements in survival. Emphasizing the importance of circulation and resuscitation is crucial, and this approach might offer benefits for various bleeding-related conditions.

Abstract
We present a case of a complex suicide of a 66-year-old man with a history of several psychiatric disorders. He attempted to commit suicide by inflicting cut wounds on his forearms, wrists, and neck but afterwards changed the method of suicide by using an electric power drill. After several unsuccessful attempts to drill a hole in either his head, thorax, or abdomen, he managed to perforate the common carotid artery on the right side of his neck and subsequently died from exsanguination.

Abstract
Objective: To evaluate the effect of a new type of sterile elastic exsanguination tourniquet (SEET) in aspiration surgery for upper limb lymphedema. Methods: The clinical data of 159 patients who underwent aspiration surgery for upper limb lymphedema from January 2017 to June 2022 in the Beijing Shijitan Hospital, Capital Medical University were retrospectively analyzed. Among them, 54 patients were treated with SEET (SEET group), while 105 patients were not treated with SEET (No-SEET group). The propensity score matching method was used, and the surgical indicators and complications were compared between the two groups. The factors affecting intraoperative bleeding volume were analyzed through multiple linear regression analysis. Results: A total of 49 pairs of patients were successfully matched by the propensity score method. The age of patients in the SEET and No-SEET groups was (57.7±8.9) years and (56.8±9.1) years, respectively. Compared with the Non-SEET group, the SEET group had less bleeding volume [(311±164) ml vs (437±173) ml, P<0.001]. The results of multiple linear regression analysis showed that the factors affecting intraoperative bleeding volume included age (β=-0.142, P=0.041), using the SEET (β=-0.249, P=0.002), surgical time (β=0.195, P=0.010) and the amount of fat mixture sucked out (β=0.464, P<0.001). Conclusions: The clinical application of the SEET in aspiration surgery for upper limb lymphedema is safe, and can significantly reduce the bleeding volume and alleviate blood shortage.

Abstract
ABSTRACT Recent advances on trauma management from the prehospital setting to in hospital care led to a better surviving severe trauma rate. Mortality from exsanguination remains the first preventable mortality. Damage-control resuscitation and surgery are evolving and thus some promising concepts are developing. Transfusion toolkit is brought on the prehospital scene while temporary bridge to hemostasis may be helpful. Panel transfusion products allow an individualized ratio assumed by fresh frozen or lyophilized plasma, fresh or cold-stored whole blood, fibrinogen, four-factor prothrombin complex concentrates. Growing interest is raising in whole blood transfusion, resuscitative endovascular balloon occlusion of the aorta use, hybrid emergency room, viscoelastic hemostatic assays to improve patient outcomes. Microcirculation, traumatic endotheliopathy, organ failures and secondary immunosuppression are point out since late deaths are increasing and may deserve specific treatment.As each trauma patient follows his own course over the following days after trauma, trauma management may be seen through successive, temporal, and individualized aims.

Abstract
ABSTRACT We report a rare case of fatal exsanguination by a wakizashi , a Japanese short sword ( shinken ). A man in his 60s was found lying on his back on his bed. He was in cardiopulmonary arrest when the ambulance crew arrived and was pronounced dead on arrival at the hospital. A wakizashi with blood stains on the blade was found on the floor, and blood was present on the bed sheets on which the man was found. Autopsy revealed an incised wound extending diagonally from superolaterally to inferomedially on the anterior left thigh as the only injury. The wound appeared mostly straight, approximately 44 cm long and 9 cm deep, with smooth walls. The left femoral artery and vein had been cleanly severed, and the cause of death was determined to be blood loss from the severed blood vessels. The wakizashi (blade length, 45 cm) was large enough to have caused the wound, and the left thigh was presumed to have been incised by a downward slash from the sword.

Abstract
ABSTRACT Deaths related to exsanguination are not rare; however, most are related to large-caliber blood vessel or organ disruption. This article reports 2 deaths from external hemorrhage arising from superficial lower extremity trauma in persons with peripheral vascular disease and anticoagulant therapy. The first involved a 78-year-old woman who was found unconscious in her home by a relative, with a plastic bag tied around her left foot and evidence of profuse hemorrhage arising from a left great toenail partial avulsion injury. The second involved a 48-year-old male resident of an adult group home who was involved in a physical altercation with a group home employee, who reportedly kicked the decedent in the right shin, resulting in extensive hemorrhage and death. The cases highlight the fact that lethal exsanguination can occur from superficial trauma. Persons with peripheral vascular disease and those taking anticoagulants may be at particular risk for such deaths.

Abstract
BACKGROUND Extra peritoneal packing (EPP) is a quick and highly effective method to control pelvic hemorrhage. OBJECTIVES To determine whether EPP can be as safely and efficiently performed in the emergency department (ED) as in the operating room (OR). METHODS Retrospective study of 29 patients who underwent EPP in the ED or OR in two trauma centers in Israel 2008-2018. RESULTS Our study included 29 patients, 13 in the ED-EPP group and 16 in the OR-EPP group. The mean injury severity score (ISS) was 34.9 ± 11.8. Following EPP, hemodynamic stability was successfully achieved in 25 of 29 patients (86.2%). A raise in the mean arterial pressure (MAP) with a median of 25 mmHg (mean 30.0 ± 27.5, P < 0.001) was documented. All patients who did not achieve hemodynamic stability after EPP had multiple sources of bleeding or fatal head injury and eventually succumbed. Patients who underwent EPP in the ED showed higher change in MAP (P = 0.0458). The overall mortality rate was 27.5% (8/29) with no difference between the OR and ED-EPP. No differences were found between ED and OR-EPP in the amount of transfused blood products, surgical site infections, and length of stay in the hospital. However, patients who underwent ED-EPP were more prone to develop deep vein thrombosis (DVT): 50% (5/10) vs. 9% (1/11) in ED and OR-EPP groups respectively (P = 0.038). CONCLUSIONS EPP is equally effective when performed in the ED or OR with similar surgical site infection rates but higher incidence of DVT.

Abstract
INTRODUCTION extremity tourniquet (TQ) use has increased in the civilian setting; the beneficial results observed in the military has influenced acceptance by EMS and bystanders. This review aimed to analyze extremity TQ types used in the civilian setting, injury site, indications, and complications. METHODS a systematic review was conducted based on original articles published in PubMed, Embase, and Cochrane following PRISMA guidelines from 2010 to 2019. Data extraction focused on extremity TQ use for hemorrhage control in the civilian setting, demographic data, study type and duration, mechanism of injury, indications for use, injury site, TQ type, TQ time, and complications. RESULTS of the 1384 articles identified, 14 were selected for review with a total of 3912 civilian victims with extremity hemorrhage and 3522 extremity TQ placements analyzed. The majority of TQs were applied to male (79%) patients, with blunt or penetrating trauma. Among the indications for TQ use were hemorrhagic shock, suspicion of vascular injuries, continued bleeding, and partial or complete traumatic amputations. Upper extremity application was the most common TQ application site (56%), nearly all applied to a single extremity (99%), and only 0,6% required both upper and lower extremity applications. 80% of the applied TQs were commercial devices, and 20% improvised. CONCLUSIONS TQ use in the civilian setting is associated with trauma-related injuries. Most are single-site TQs applied for the most part to male adults with upper extremity injury. Commercial TQs are more commonly employed, time in an urban setting is under 1 hour, with few complications described.

Abstract
Menkes disease (MD) usually presents in infancy with respiratory and neurological complications. Severe isolated vasculo-connective tissue involvement in infancy is rare, and hence the precise and timely diagnosis is difficult. We report a case of an 8-week-old male infant who succumbed to acute, severe exsanguination, and hemorrhagic shock secondary to a large retroperitoneal hematoma due to rupture of a right iliac artery aneurysm. Perimortem musculoskeletal findings raised suspicion of nonaccidental injury. However, postmortem review of facial traits raised the suspicion of MD. MD was subsequently confirmed on genetic testing. Child health clinicians must remain aware of MD as a rare cause of infant vasculopathy or atypical skeletal abnormalities.

Abstract
Trauma remains a leading cause of death worldwide, and most early preventable deaths in both the civilian and military settings are due to uncontrolled hemorrhage, despite paradigm advances in modern trauma care. Combined tissue injury and shock result in hemostatic failure, which has been identified as a multidimensional molecular, physiologic and clinical disorder termed trauma-induced coagulopathy (TIC). Understanding the biology of TIC is of utmost importance, as it is often responsible for uncontrolled bleeding, organ failure, thromboembolic complications, and death. Investigations have shown that TIC is characterized by multiple phenotypes of impaired hemostasis due to altered biology in clot formation and breakdown. These coagulopathies are attributable to tissue injury and shock, and encompass underlying endothelial, immune and inflammatory perturbations. Despite the recognition and identification of multiple mechanisms and mediators of TIC, and the development of targeted treatments, the mortality rates and associated morbidities due to hemorrhage after injury remain high. The purpose of this review is to examine the past and present understanding of the multiple distinct but highly integrated pathways implicated in TIC, in order to highlight the current knowledge gaps and future needs in this evolving field, with the aim of reducing morbidity and mortality after injury.

Abstract
OBJECTIVES Uncontrolled bleeding from serious injuries continues to be one of the main causes of preventable deaths outside hospitals. Tourniquets could be useful for quickly stemming blood flow and prevent exsanguination, although evidence supporting their use and effectiveness in civilian accidents is limited. To analyze the effectiveness of tourniquets for stopping bleeding in out-of-hospital emergencies and to explore factors associated with effectiveness. MATERIAL AND METHODS We undertook a systematic review of the literature in Spanish and English. Search protocols to identify studies that evaluated the use of various devices and their effectiveness in stemming arterial blood flow. We included studies published between 2011 and 2016 in which tourniquets were used to prevent massive blood loss. RESULTS We included 17 articles. Tourniquets were effective in stopping massive bleeding in all studies. Pain, the most frequently described adverse effect, was observed in 420 patients (35.7%). Delayed application of a tourniquet was associated with more negative outcomes. CONCLUSION Tourniquets are effective for stopping massive blood loss. There are few complications, most of which are attributable to the critical state of patients rather than to application of the tourniquet. A tourniquet should be applied in major trauma cases in civilian settings if massive, life-threatening bleeding cannot be stopped with direct pressure.

Abstract
Accidental cut-throat injuries are extremely rare and usually involve a sharp-edged weapon. In this paper, two cases of a cut-throat wound to two auto-rickshaw drivers are presented where the broken windshield of the auto-rickshaws was responsible for the wounds. In both the cases, fatal incised wounds were present over the neck, cutting the soft tissue along with the major vessels. The death occurred due to exsanguination caused by neck-vessel injury in one case and trachea along with neck-vessel injury in the second case. Although the wounds on the neck initially suggested homicide, they were found to have occurred accidentally as a result of a road traffic accident involving a head-on collision of auto rickshaws. The injuries were inflicted by the shattered glass of the windshield.

Abstract
Neurologic deficit subsequent to cardiac surgery remains a cause of postoperative morbidity and mortality. Although myriad risk factors for postoperative cognitive decline have been identified, their individual influence remains undefined. Although less emphasis is now placed on the heart lung machine as the major source of postoperative cognitive decline, the conduct of cardiopulmonary bypass and, in particular, the management of the bypass circuit remain key to patient safety. We present a case of inadvertent intraoperative exsanguination of a patient following open heart surgery for implantation of a left ventricular assist device. The patient suffered significant neurologic damage. However, the nature of the patient's cerebral injury indicated thromboembolism as the likely cause, rather than hypoxic-ischemic injury caused by hypoperfusion. Subsequent investigation of the incident identified several possible sources and potential causes of embolization to the brain that could not rule out the exsanguination event as a contributing factor.

Abstract
Venous disease, including varicose veins and chronic venous insufficiency, is one of the most common chronic medical conditions. Haemorrhage from rupture of varicose veins in the legs is rare and can lead to sudden death. Nevertheless, this condition is not included among the causes of sudden death. In this case, an 88-year-old man was found dead in a large pool of blood at home. Initially, investigators mistakenly assumed that it was a case of homicide. Bloodstain pattern analysis was performed. An external examination of the victim showed an ulcer on the left foot and evident varicose veins untreated on the lower limbs. The aim of this study is to emphasize the role of treatment of varicose veins in the prevention of adverse events such as sudden death from acute haemorrhage.

Abstract
IMPORTANCE Severely injured patients experiencing hemorrhagic shock often require massive transfusion. Earlier transfusion with higher blood product ratios (plasma, platelets, and red blood cells), defined as damage control resuscitation, has been associated with improved outcomes; however, there have been no large multicenter clinical trials. OBJECTIVE To determine the effectiveness and safety of transfusing patients with severe trauma and major bleeding using plasma, platelets, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio. DESIGN, SETTING, AND PARTICIPANTS Pragmatic, phase 3, multisite, randomized clinical trial of 680 severely injured patients who arrived at 1 of 12 level I trauma centers in North America directly from the scene and were predicted to require massive transfusion between August 2012 and December 2013. INTERVENTIONS Blood product ratios of 1:1:1 (338 patients) vs 1:1:2 (342 patients) during active resuscitation in addition to all local standard-of-care interventions (uncontrolled). MAIN OUTCOMES AND MEASURES Primary outcomes were 24-hour and 30-day all-cause mortality. Prespecified ancillary outcomes included time to hemostasis, blood product volumes transfused, complications, incidence of surgical procedures, and functional status. RESULTS No significant differences were detected in mortality at 24 hours (12.7% in 1:1:1 group vs 17.0% in 1:1:2 group; difference, -4.2% [95% CI, -9.6% to 1.1%]; P = .12) or at 30 days (22.4% vs 26.1%, respectively; difference, -3.7% [95% CI, -10.2% to 2.7%]; P = .26). Exsanguination, which was the predominant cause of death within the first 24 hours, was significantly decreased in the 1:1:1 group (9.2% vs 14.6% in 1:1:2 group; difference, -5.4% [95% CI, -10.4% to -0.5%]; P = .03). More patients in the 1:1:1 group achieved hemostasis than in the 1:1:2 group (86% vs 78%, respectively; P = .006). Despite the 1:1:1 group receiving more plasma (median of 7 U vs 5 U, P < .001) and platelets (12 U vs 6 U, P < .001) and similar amounts of red blood cells (9 U) over the first 24 hours, no differences between the 2 groups were found for the 23 prespecified complications, including acute respiratory distress syndrome, multiple organ failure, venous thromboembolism, sepsis, and transfusion-related complications. CONCLUSIONS AND RELEVANCE Among patients with severe trauma and major bleeding, early administration of plasma, platelets, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio did not result in significant differences in mortality at 24 hours or at 30 days. However, more patients in the 1:1:1 group achieved hemostasis and fewer experienced death due to exsanguination by 24 hours. Even though there was an increased use of plasma and platelets transfused in the 1:1:1 group, no other safety differences were identified between the 2 groups.

Conceptualized Use of Self-Expanding Foam to Rescue Special Operators From Abdominal Exsanguination: Percutaneous Damage Control for the Forward Deployed. JOURNAL OF SPECIAL OPERATIONS MEDICINE : A PEER REVIEWED JOURNAL FOR SOF MEDICAL PROFESSIONALS 2015; 15:39-45.

Abstract
BACKGROUND Noncompressible hemorrhage is the leading cause of potentially survivable death on the battlefield. In Special Operations Forces (SOF), 50% of potentially survivable deaths have been related to noncompressible hemorrhage. Currently, there are no widely available presurgical interventions that can slow abdominal bleeding. Consequently, many of the preventable deaths occur en route to definitive care as a failure to rescue from exsanguination. A self-expanding polyurethane foam has been developed as a percutaneous damage control intervention to rescue casualties who would otherwise die of noncompressible hemorrhage, and allow them to survive long enough to reach surgical intervention. The purpose of this paper is to summarize the existing preclinical data, describe the role of SOF personnel in foam delivery-system development, and to integrate these together to conceptualize how foam could be incorporated into SOF medical care. METHODS All existing publications on self-expanding foam are reviewed. Additionally, eight SOF medical providers with combat experience provided end-user input to delivery-device design through an interactive human-factors testing process. RESULTS Ten preclinical publications described efficacy, safety, dose translation, and risk-benefit analysis of exsanguination rescue with percutaneous-foam damage control. SOF medical providers guided weight, cubic, operational requirements, and limits for the foam delivery device. CONCLUSION Presurgical exsanguination rescue with percutaneous foam damage control is safe and effective with a favorable risk-benefit profile in preclinical studies. Battlefield, presurgical use by SOF medical providers is conceptually possible. Adoption of the technology on the battlefield should proceed with SOF medical provider input.

Sheath hemorrhage after percutaneous ventricular assist device implantation. CONNECTICUT MEDICINE 2014; 78:203-206. [PMID: 24830115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/03/2023]
Abstract
Technical advances in temporary ventricular assist devices (VADs) continue to progress, allowing for percutaneous implantation during times of hemodynamic instability. However, device delivery systems, i.e., sheaths, lag in their ability to sustain the mechanical demands of these VADs for extended periods. We propose both a novel technique and the implementation of an emergency preparedness plan to be enacted specifically during those times when delivery systems fail thereby leading to potentially catastrophic bleeding complications.

Abstract
UNLABELLED Acute coagulopathy with exsanguinating bleeding occurs in 2-5% of all trauma cases carrying mortality rate near 100% after conventional management. In the last few decades, the development of damage control surgery (DCS) in combination with the technique of open abdomen led to significantly improved survival among these patients. MATERIAL AND METHODS A descriptive study based on a retrospective analysis of 12 consecutive blast victims with exsanguinating bleeding underwent DCS and open abdomen management. All patients were soldiers injured during their deployment in Iraq and Afghanistan during 2002-2007, treated by our deployed surgical teams. Vacuum Assisted Closure (V.A.C., KCI) and vacuum pack (VP) was used for a temporary closure of abdomen. A cumulative analysis of all relevant series used these methods during the period 2000-2013 was performed. RESULTS DCS was applied in 12 of 114 consecutive blast victims (10.5%) with survival rate 66.7% (8/12). Eleven had open abdomen with temporary closure with V.A.C. in 6 and VP in 5. Four patients died before the definitive closure (36.4%). The survivors (n = 8) were with a mean age 28.5 years, suffered from a critical trauma with a mean Injury Severity Score 35.5. V.A.C was used in 4 of them, VP in 3. Primary closure of abdomen was achieved in 6 (85.7%) within 3.5 days and mean 1.3 dressing changes. Due to ACS, the abdomen was closed through skin suture only and a creation of planned ventral hernia in 1 patient treated with VP (1/7, 14.3%). Wound infection was observed in 1 case (14.3%). CONCLUSION Despite the small sample size, our series clearly demonstrate the benefits of DCS and open abdomen in trauma patients with exsangiunating bleeding. The survival rate is highly dependent on the rapid implementation of DCS in properly selected patients. V.A.C. and VP provide a high rate of primary fascial closure in trauma.

Abstract
Injuries caused by chain saws are mostly seen due to accidents. Suicides by chain saws are rare, but some cases have already been described. We present the case of homicide on a child by a chain saw followed by the suicide of his father. For the homicide and the suicide chain saws of different sizes were used. Fatal injuries in the homicide and suicide were located on the neck. Cause of death in both cases was fatal haemorrhage with blood aspiration respectively decapitation. Normally, in suicide by use of chain saws individuals suffering from schizophrenia, major depression and alcohol or drug dependence are concerned. In the presented case, the background was a litigation of a divorced couple for child custody.

Early death and late morbidity after blood transfusion of injured children: a pilot study. J Pediatr Surg 2012; 47:1587-91. [PMID: 22901922 DOI: 10.1016/j.jpedsurg.2012.02.011] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2011] [Revised: 02/07/2012] [Accepted: 02/20/2012] [Indexed: 11/19/2022]
Abstract
BACKGROUND/PURPOSE Early postinjury death after packed red blood cell (pRBC) transfusion is attributed to uncontrolled hemorrhage and coagulopathy. The adverse immunomodulatory effects of blood transfusion are implicated in subsequent morbidity. We hypothesized that injured children requiring pRBC transfusion demonstrate patterns in outcome similar to those observed in adults. METHODS Our prospectively collected trauma registry was queried for demographics, treatment, and outcome (2006-2009). Outcomes of children who received pRBC transfusion were compared with those of age- and Injury Severity Score (ISS)-matched children who did not receive pRBC transfusion by both univariate and multivariable analysis. RESULTS Eight percent (43/512) of injured children received a pRBC transfusion: 20 early and 23 late. The likelihood of pRBC transfusion increased with increasing ISS (ISS <15, 2%; ISS 16-25, 17%; ISS >25, 72%). One-half of injured children who received an early pRBC transfusion died; however, most deaths were because of central nervous system injury. Both ventilator and intensive care unit days were increased in children who received pRBC transfusion as compared with those who did not. CONCLUSION Early pRBC transfusion is associated with a high mortality in children. Late blood transfusion is associated with worse outcomes, although this relationship may not be causal. This pilot study provides evidence of an association between pRBC transfusion, morbidity, and mortality among injured children that warrants refinement in larger, prospective investigations.

Abstract
BACKGROUND The hemodynamically unstable pelvic fracture are a diagnostic and therapeutic challenge. The current management is based on the control of pelvic bleeding by combining pelvic ring stabilization and embolization of pelvic arteries. The mortality of these patients, however, exceeds 30%. Recently the preperitoneal packing, based on the hemostatic tamponade of the pelvic cavity has been described. The objective of this study was to evaluate the interest of this new surgical procedure. The effectiveness of the standard algorithm is evaluated by analysis of pelvic injuries in 200 severe trauma treated at the Sainte-Anne Hospital. The results are then compared with literature data on the preperitoneal packing. PATIENTS AND METHODS The profile injury, management and morbidity and mortality was evaluated in 200 polytrauma. After an initial phase of resuscitation, unstable pelvic fractures were treated with a circumferential belt followed by the application of an external fixator. Arteriography was performed for all patients with persistent hemodynamic instability. RESULTS The mean injury severity score (ISS) was 31 (4-75). The mean trauma-related injury severity score (TRISS) was 74% (3-99). The proportion of hemodynamically unstable patients was 47%. Fifteen patients (41%) had severe bleeding. The median number of blood transfusion was 10 (4-42); eight patients (22%) underwent embolization. For two patients, reducing the pelvic fracture with an external fixator resulted in permanent hemostasis. Two patients underwent a laparotomy first, for the control of a hemoperitoneum. The mortality rate of the group of patients with hemorrhage was 33% (5/15). DISCUSSION This high mortality leads to reconsider the place of pelvic embolization as firstline treatment. Some major drawbacks are noted: its effectiveness in treating venous bleeding, availability and duration of the procedure. The preperitoneal packing is a fast and effective surgical alternative. It seems to improve hemodynamic status of patients and significantly reduce the use of embolization and massive transfusion. Embolization is still indicated for patients not responding to surgery. However survival is not significantly improved.

Abstract
The placenta accreta is the second leading cause of obstetric hemorrhage in the world. In many occasions it is necessary to make an obstetric hysterectomy, a circumstance that increases morbidity, and maternal mortality. Communicates a surgical alternative to hysterectomy obstetric that has enabled us to reduce until the time to zero our rate of maternal deaths by obstetric hemorrhage, in addition to reducing the surgical time and the associated morbidity, without changing the perinatal outcome.
