Splenic trauma: WSES classification and guidelines for adult and pediatric patients

Spleen injuries are among the most frequent trauma-related injuries. At present, they are classified according to the anatomy of the injury. The optimal treatment strategy, however, should keep into consideration the hemodynamic status, the anatomic derangement, and the associated injuries. The management of splenic trauma patients aims to restore the homeostasis and the normal physiopathology especially considering the modern tools for bleeding management. Thus, the management of splenic trauma should be ultimately multidisciplinary and based on the physiology of the patient, the anatomy of the injury, and the associated lesions. Lastly, as the management of adults and children must be different, children should always be treated in dedicated pediatric trauma centers. In fact, the vast majority of pediatric patients with blunt splenic trauma can be managed non-operatively. This paper presents the World Society of Emergency Surgery (WSES) classification of splenic trauma and the management guidelines

Correlation between Extravascular Lung Water and Oxygenation in ALI/ARDS Patients in Septic Shock: Possible Role in the Development of Atelectasis?

This study aimed to evaluate the relationship between PaO2/FiO2 ratio and extravascular lung water in septic shock- induced acute respiratory distress syndrome in a prospective observational clinical trial. Twenty-three patients suffering from sepsis induced acute respiratory distress syndrome were recruited. All patients were ventilated in pressure control/support mode. Haemodynamic parameters were determined by arterial thermodilution (PiCCO) eight hourly for 72 hours. At the same time blood gas analyses were done and respiratory parameters were also recorded. Data are presented as mean±SD. For statistical analysis Pearson’s correlation test, and analysis of variance (ANOVA) was used respectively. Significant negative correlation was found between extravascular lung water and PaO2/FiO2 (r= –0.355, P<0.001), and significant positive correlation was shown between extravascular lung water and PEEP (r=0.557, P<0.001). A post-hoc analysis was performed when “low” PEEP: <10 cmH2O and “high” PEEP: (10 cmH2O PEEP was applied, and neither the oxygenation, nor the driving pressure or the PaCO2 differed significantly, but the extravascular lung water showed significant difference when “high” or “low” PEEP was applied (13±5 vs 9±2 ml/kg respectively, P=0.001). This study found significant negative correlation between extravascular lung water and PaO2/FiO2. The mechanism by which extravascular lung water affects oxygenation is unknown but the significant positive correlation between PEEP and extravascular lung water shown in this trial suggests that the latter may have a role in the development of alveolar atelectasis

Nonoperative Management of Blunt Splenic Trauma: Also Feasible and Safe in Centers with Low Trauma Incidence and in the Presence of Established Risk Factors

Background: Treatment of blunt splenic trauma has undergone dramatic changes over the last few decades. Nonoperative management (NOM) is now the preferred treatment of choice, when possible. The outcome of NOM has been evaluated. This study evaluates the results following the management of blunt splenic injury in adults in a Swedish university hospital with a low blunt abdominal trauma incidence. Method: Fifty patients with blunt splenic trauma were treated at the Department of Surgery, Lund University Hospital from January 1994 to December 2003. One patient was excluded due to a diagnostic delay of > 24 h. Charts were reviewed retrospectively to examine demographics, injury Severity score (ISS), splenic injury grade, diagnostics, treatment and outcome measures. Results: Thirty-nine patients (80%) were initially treated nonoperatively (NOM), and ten (20%) patients underwent immediate surgery (operative management, OM). Only one (3%) patient failed NOM and required surgery nine days after admission (failure of NOM, FNOM). The patients in the OM group had higher ISS (p < 0.001), higher grade of splenic injury (p < 0.001), and were hemodynamically unstable to a greater extent (p < 0.001). This was accompanied by increased transfusion requirements (p < 0.001), longer stay in the ICU unit (p < 0.001) and higher costs (p = 0.001). Twenty-seven patients were successfully treated without surgery. No serious complication was found on routine radiological follow-up. Conclusion: Most patients in this study were managed conservatively with a low failure rate of NOM. NOM of blunt splenic trauma could thus be performed in a seemingly safe and effective manner, even in the presence of established risk factors. Routine follow-up with CT scan did not appear to add clinically relevant information affecting patient management

Kidney and uro-trauma: WSES-AAST guidelines

Contains fulltext : 215819.pdf (publisher's version ) (Open Access)Renal and urogenital injuries occur in approximately 10-20% of abdominal trauma in adults and children. Optimal management should take into consideration the anatomic injury, the hemodynamic status, and the associated injuries. The management of urogenital trauma aims to restore homeostasis and normal physiology especially in pediatric patients where non-operative management is considered the gold standard. As with all traumatic conditions, the management of urogenital trauma should be multidisciplinary including urologists, interventional radiologists, and trauma surgeons, as well as emergency and ICU physicians. The aim of this paper is to present the World Society of Emergency Surgery (WSES) and the American Association for the Surgery of Trauma (AAST) kidney and urogenital trauma management guidelines
