[Treatment of Burn Shock - The First 24 hours and Beyond]. / Die Therapie des Verbrennungsschocks ­ die ersten 24 h und darüber hinaus.

Acute phase and resuscitation after burn trauma are challenging even for specialised burn centres due to the individual onset and differences compared with other forms of shock. The guidelines of the German Society of Burn Medicine (DGV) cover the scientific basis of modern burn treatment. Nevertheless, uncertainty remains regarding the detailed practical handling. This expert consensus focuses on best practices for the treatment of patients with major burns in specialised burn centres and by clinical first responders.

[Treatment of a severely injured with active bleeding under apixaban and residual anticoagulatory activity]. / Schwerstverletztenversorgung mit aktiver Blutung unter Apixaban und gerinnungsrelevanter Restaktivität.

Direct oral anticoagulants (DOAC) are increasingly being prescribed for prophylaxis of thromboembolic events. Their use, particularly in emergency settings is difficult as blood level measurements are often not immediately available and until recently there was no possibility for reversal. This article presents the case of a severely injured patient with life-threatening traumatic bleeding under long-term treatment with the factor Xa inhibitor apixaban, viscoelasticity-based detection of residual systemic anticoagulatory activity and targeted reversal.

Current understanding of thermo(dys)regulation in severe burn injury and the pathophysiological influence of hypermetabolism, adrenergic stress and hypothalamic regulation-a systematic review.

Background: In this systematic review, we summarize the aetiology as well as the current knowledge regarding thermo(dys)regulation and hypothermia after severe burn trauma and aim to present key concepts of pathophysiology and treatment options. Severe burn injuries with >20% total body surface area (TBSA) affected commonly leave the patient requiring several surgical procedures, prolonged hospital stays and cause substantial changes to body composition and metabolism in the acute and long-term phase. Particularly in severely burned patients, the loss of intact skin and the dysregulation of peripheral and central thermoregulatory processes may lead to substantial complications. Methods: A systematic and protocol-based search for suitable publications was conducted following the PRISMA guidelines. Articles were screened and included if deemed eligible. This encompasses animal-based in vivo studies as well as clinical studies examining the control-loops of thermoregulation and metabolic stability within burn patients. Results: Both experimental animal studies and clinical studies examining thermoregulation and metabolic functions within burn patients have produced a general understanding of core concepts which are, nonetheless, lacking in detail. We describe the wide range of pathophysiological alterations observed after severe burn trauma and highlight the association between thermoregulation and hypermetabolism as well as the interactions between nearly all organ systems. Lastly, the current clinical standards of mitigating the negative effects of thermodysregulation and hypothermia are summarized, as a comprehensive understanding and implementation of the key concepts is critical for patient survival and long-term well-being. Conclusions: The available in vivo animal models have provided many insights into the interwoven pathophysiology of severe burn injury, especially concerning thermoregulation. We offer an outlook on concepts of altered central thermoregulation from non-burn research as potential areas of future research interest and aim to provide an overview of the clinical implications of temperature management in burn patients.

[Target Temperature Control in Patients with Burns]. / Zieltemperaturkontrolle beim Patienten mit Verbrennungen.

Severe burns lead to a persistent hypermetabolic response of the organism with significantly increased resting energy turnover, multi-organ dysfunction, muscle breakdown and increased risk of infection. Elevated core and skin temperatures are characteristic. A further increase in the metabolic rate can be triggered by heat losses, for which these patients are particularly predisposed due to high heat dissipation via evaporation of moisture and impairment of the thermoregulatory and insulating properties of the burnt skin. This is especially true in all treatment situations with exposure to large, uncovered skin surfaces, such as primary care, dressing changes in the intensive care unit and surgery with extensive sterile operating field. It has been shown that hypothermia is associated with numerous risks for the burn patient. Consistent heat management with measurement of the core body temperature and application of external and internal heat protection measures is recommended. Traditionally, an increase in room temperature is used here. However, this effective measure is limited by the resilience of the intensive care practitioners and the surgeons. To avoid perioperative hypothermia, strict surgical planning with limitation of the duration of surgery and close intraoperative communication about the risk of hypothermia are of particular importance.The differentiation between accepted temperature increase and infectious fever is often only possible by the inclusion of further examination findings. The criterion for sepsis is a temperature above 39 °C or below 36.5 °C.

Broken guide wire--a fault of design?

PURPOSE: To report a potentially serious complication resulting from a faulty guide wire during central venous catheterization. CLINICAL FEATURES: We report breakage of a guide wire with potential severe implications for a 47-yr-old critical care patient. The tip of the J-wire became lodged in the internal jugular vein, and required fluoroscopic guidance for removal, which occurred without complication. CONCLUSION: Breakage of a guide wire during central venous catheter insertion has been very rarely reported. However, inherent faults in design or in the manufacturing process of the guide wire could lead to this rare complication. A simple bedside test is proposed to detect breakage in the core section of the guide wire.
