[Treatment of sepsis-induced coagulopathy : Results of a Germany-wide survey in intensive care units]

[Guideline-conform treatment of sepsis]

The time to administration of broad-spectrum antibiotics and (secondarily) to the initiation of hemodynamic stabilization are the most important factors influencing survival of patients with sepsis and septic shock; however, the basic prerequisite for the initiation of an adequate treatment is that a suspected diagnosis of sepsis is made first. Therefore, the treatment of sepsis, even before it has begun, is an interdisciplinary and interprofessional task. This article provides an overview of the current state of the art in sepsis treatment and points towards new evidence that has the potential to change guideline recommendations in the coming years. In summary, the following points are critical: (1) sepsis must be diagnosed as soon as possible and the implementation of a source control intervention (in case of a controllable source) has to be implemented as soon as (logistically) possible. (2) In general, intravenous broad-spectrum antibiotics should be given within the first hour after diagnosis if sepsis or septic shock is suspected. In organ dysfunction without shock, where sepsis is a possible but unlikely cause, the results of focused advanced diagnostics should be awaited before a decision to give broad-spectrum antibiotics is made. If it is not clear within 3 h whether sepsis is the cause, broad-spectrum antibiotics should be given when in doubt. Administer beta-lactam antibiotics as a prolonged (or if therapeutic drug monitoring is available, continuous) infusion after an initial loading dose. (3) Combination treatment with two agents for one pathogen group should remain the exception (e.g. multidrug-resistant gram-negative pathogens). (4) In the case of doubt, the duration of anti-infective treatment should rather be shorter than longer. Procalcitonin can support the clinical decision to stop (not to start!) antibiotic treatment! (5) For fluid treatment, if hypoperfusion is present, the first (approximately) 2L (30 ml/kg BW) of crystalloid solution is usually safe and indicated. After that, the rule is: less is more! Any further fluid administration should be carefully weighed up with the help of dynamic parameters, the patient's clinical condition and echo(cardio)graphy.

[Practice of pharmaceutical thrombosis prophylaxis and anticoagulation in patients with sepsis and pre-existing anticoagulation or heparin-induced type II thrombocytopenia-Results of a nationwide survey in German intensive care units]

BACKGROUND

A pre-existing anticoagulation treatment and predisposing diseases for thromboembolic events represent common problems in patients with sepsis or septic shock; however, these conditions are not addressed in current national guidelines for sepsis and septic shock. One of the aims of this nationwide survey in Germany was therefore to determine how intensive care physicians deal with these problems.

METHODS

From October 2019 to May 2020, we conducted a nationwide survey among German medical directors of intensive care units (ICU) addressing anticoagulation and drug-based prophylaxis of venous thromboembolism (VTE) in patients with sepsis and sepsis-induced coagulopathy. One focus was the procedure for patients with a pre-existing anticoagulation treatment or a previously known heparin-induced thrombocytopenia (HIT) type 2 (acute symptomatic vs. dating back years).

RESULTS

In most of the participating ICUs pre-existing anticoagulation is largely continued with low molecular weight heparin preparations or unfractionated heparin. In patients with pre-existing HIT type 2 both acute symptomatic and dating back years, argatroban represents the drug of choice. There is a high degree of variability in the definition of the target values, usually being well above the range for pure VTE prophylaxis.

CONCLUSION

Data on the continuation of anticoagulation beyond VTE prophylaxis with a subsequently increased risk of bleeding in patients with sepsis and septic shock is limited and treatment decisions are in many cases subject to individual consideration by the practitioner. The results of our survey imply the need for a systematic work-up of this topic in order to support daily practice in many ICUs with the required evidence.

[SEPSIS-3.0-Is intensive care medicine ready for ICD-11?]

BACKGROUND

The 11th revision of the International Classification of Diseases (ICD-11) will come into effect in January 2022. Among other things, The Third International Consensus Definitions for Sepsis and Septic Shock (SEPSIS‑3 definition) will be implemented in it. This defines sepsis as a "life-threatening organ dysfunction caused by a dysregulated host response to infection". The aim of the present secondary analysis of a survey on the topic of "sepsis-induced coagulopathy" was to evaluate whether the SEPSIS‑3 definition, 4 years after its international introduction, has arrived in everyday clinical practice of intensive care units (ICU) run by anesthesiologists in Germany and thus the requirements for its use of the ICD-11 are given.

METHODS

Between October 2019 and May 2020, we carried out a nationwide survey among German medical directors of ICUs. In a separate block of questions we asked about the definition of sepsis used in daily practice. In addition, we asked whether the quick-sequential (sepsis-related) organ failure assessment (qSOFA) score is used in screening for sepsis in the hospital to which to the participating ICU belongs.

RESULTS

A total of 50 medical directors from anesthesiological ICUs took part in the survey. In total, the ICUs evaluated stated that they had around 14% of the high-care beds registered in Germany. The SEPSIS‑3 definition is integrated into everyday clinical practice at 78.9% of the university hospitals and 84.0% of the participating teaching hospitals. In contrast, the qSOFA screening test is only used by 26.3% of the participating university hospitals, but at least 52% of the teaching hospitals and 80% of the other hospitals.

CONCLUSION

The data show that both SEPSIS‑3 and qSOFA have become part of everyday clinical practice in German hospitals. The cautious use of qSOFA at university hospitals with simultaneous broad acceptance of the SEPSIS‑3 definition can be interpreted as an indication that the search for a suitable screening test for sepsis has not yet been completed.

[Update of the Surviving Sepsis Campaign guidelines 2021-What is new?]

The revised and redefined "International Guidelines for Management of Sepsis and Septic Shock 2021" of the Surviving Sepsis Campaign were published on 4 October 2021. As in the previous version from 2016, the focus of these international guidelines is on the diagnosis and acute treatment measures in sepsis. The topics long-term outcome and treatment targets for rehabilitation are extensively discussed and accompanied by specific recommendations. These recommendations and the underlying studies reflect the increasing awareness about the long-term consequences of severe diseases requiring intensive medical care. This article summarizes the updates in a clearly comprehensible form.

[Anticoagulation in intensive care medicine]

Kritisch kranke Patienten sind in hohem Maße durch Störungen der Hämostase gefährdet, diese können sowohl mit einer verstärkten Blutungsneigung als auch mit einem erhöhten Risiko für thromboembolische Ereignisse einhergehen. Bei akuten vaskulären Ereignissen ist die spezifische Therapie mit medikamentöser Antikoagulation bzw. Plättchenaggregationshemmung essenziell, bei Patienten mit Vorerkrankungen ist die angepasste Fortführung einer vorbestehenden Antikoagulation während intensivmedizinischer Behandlung von Bedeutung, des Weiteren sind sowohl medikamentöse Thromboseprophylaxe als auch die Frage nach potenziell therapeutischen Optionen, wie Antikoagulanzien bei Sepsis und infektionsgetriggerten Störungen der Blutgerinnung, im klinischen Alltag wichtig. Spezifische Fragestellungen ergeben sich bei der Anwendung extrakorporaler Maßnahmen wie Nierenersatzverfahren sowie Kreislaufunterstützungs- und Ersatzverfahren. In den letzten Jahren sind eine Reihe neuer Präparate zur Antikoagulation und Plättchenhemmung verfügbar geworden. Die Therapiekontrolle über labordiagnostische Verfahren stellt einen zentralen Punkt dar. In dieser Übersichtsarbeit werden aktuelle Aspekte zu diesen Themen praxisnah aufgeführt.
