[Recommendations for the management of critically ill patients with COVID-19 in Intensive Care Units]

La pandemia por COVID-19 ha provocado el ingreso de un elevado número de pacientes en UCI, generalmente por insuficiencia respiratoria severa. Desde la aparición de los primeros casos de infección por SARS-CoV-2, a finales de 2019, en China, se ha publicado una cantidad ingente de recomendaciones de tratamiento de esta entidad, no siempre respaldadas por evidencia científica suficiente ni con el rigor metodológico necesario. Gracias al esfuerzo de distintos grupos de investigadores, actualmente disponemos de resultados de ensayos clínicos, y otro tipo de estudios, de mayor calidad. Consideramos necesario realizar un documento que incluya recomendaciones que recojan estas evidencias en cuanto al diagnóstico y tratamiento de la COVID-19, pero también aspectos que otras guías no han contemplado y que consideramos fundamentales en el manejo del paciente crítico con COVID-19. Para ello se ha creado un comité redactor, conformado por miembros de los Grupos de Trabajo de SEMICYUC más directamente relacionados con diferentes aspectos específicos del manejo de estos pacientes.

Efficacy and safety of early target-controlled plasma volume replacement with a balanced gelatine solution versus a balanced electrolyte solution in patients with severe sepsis/septic shock: study protocol, design, and rationale of a prospective, randomized, controlled, double-blind, multicentric, international clinical trial : GENIUS-Gelatine use in ICU and sepsis

BACKGROUND

Sepsis is associated with capillary leakage and vasodilatation and leads to hypotension and tissue hypoperfusion. Early plasma volume replacement is required to achieve haemodynamic stability (HDS) and maintain adequate tissue oxygenation. The right choice of fluids to be used for plasma volume replacement (colloid or crystalloid solutions) is still a matter of debate, and large trials investigating the use of colloid solutions containing gelatine are missing. This study aims to investigate the efficacy and safety of plasma volume replacement using either a combined gelatine-crystalloid regime (1:1 ratio) or a pure crystalloid regime.

METHODS

This is a prospective, controlled, randomized, double-blind, international, multicentric phase IV study with two parallel groups that is planned to be conducted at European intensive care units (ICUs) in a population of patients with hypovolaemia in severe sepsis/septic shock. A total of 608 eligible patients will be randomly assigned to receive either a gelatine-crystalloid regime (Gelaspan® 4% and Sterofundin® ISO, B. Braun Melsungen AG, in a 1:1 ratio) or a pure crystalloid regime (Sterofundin® ISO) for plasma volume replacement. The primary outcome is defined as the time needed to achieve HDS. Plasma volume replacement will be target-controlled, i.e. fluids will only be administered to volume-responsive patients. Volume responsiveness will be assessed through passive leg raising or fluid challenges. The safety and efficacy of both regimens will be assessed daily for 28 days or until ICU discharge (whichever occurs first) as the secondary outcomes of this study. Follow-up visits/calls will be scheduled on day 28 and day 90.

DISCUSSION

This study aims to generate evidence regarding which regimen-a gelatine-crystalloid regimen or a pure crystalloid regimen-is more effective in achieving HDS in critically ill patients with hypovolaemia. Study participants in both groups will benefit from the increased safety of target-controlled plasma volume replacement, which prevents fluid administration to already haemodynamically stable patients and reduces the risk of harmful fluid overload.

The current COVID-19 pandemic has rendered up to 15% of patients under mechanical ventilation. Because the subsequent tracheotomy is a frequent procedure, the three societies mostly involved (SEMICYUC, SEDAR and SEORL-CCC) have setup a consensus paper that offers an overview about indications and contraindications of tracheotomy, be it by puncture or open, clarifying its respective advantages and enumerating the ideal conditions under which they should be performed, as well as the necessary steps. Regular and emergency situations are displayed together with the postoperative measures.

Clinical consensus recommendations regarding non-invasive respiratory support in the adult patient with acute respiratory failure secondary to SARS-CoV-2 infection

Coronavirus disease 2019 (COVID-19) is a respiratory tract infection caused by a newly emergent coronavirus, that was first recognized in Wuhan, China, in December 2019. Currently, the World Health Organization (WHO) has defined the infection as a global pandemic and there is a health and social emergency for the management of this new infection. While most people with COVID-19 develop only mild or uncomplicated illness, approximately 14% develop severe disease that requires hospitalization and oxygen support, and 5% require admission to an intensive care unit. In severe cases, COVID-19 can be complicated by the acute respiratory distress syndrome (ARDS), sepsis and septic shock, and multiorgan failure. This consensus document has been prepared on evidence-informed guidelines developed by a multidisciplinary panel of health care providers from four Spanish scientific societies (Spanish Society of Intensive Care Medicine [SEMICYUC], Spanish Society of Pulmonologists [SEPAR], Spanish Society of Emergency [SEMES], Spanish Society of Anesthesiology, Reanimation, and Pain [SEDAR]) with experience in the clinical management of patients with COVID-19 and other viral infections, including SARS, as well as sepsis and ARDS. The document provides clinical recommendations for the noninvasive respiratory support (noninvasive ventilation, high flow oxygen therapy with nasal cannula) in any patient with suspected or confirmed presentation of COVID-19 with acute respiratory failure.

This consensus guidance should serve as a foundation for optimized supportive care to ensure the best possible chance for survival and to allow for reliable comparison of investigational therapeutic interventions as part of randomized controlled trials.

Contingency Plan for the Intensive Care Services for the COVID-19 pandemic

In January 2020, the Chinese authorities identified a new virus of the Coronaviridae family as the cause of several cases of pneumonia of unknown aetiology. The outbreak was initially confined to Wuhan City, but then spread outside Chinese borders. On 31 January 2020, the first case was declared in Spain. On 11 March 2020, The World Health Organisation (WHO) declared the coronavirus outbreak a pandemic. On 16 March 2020, there were 139 countries affected. In this situation, the Scientific Societies SEMICYUC and SEEIUC, have decided to draw up this Contingency Plan to guide the response of the intensive care services. The objectives of this plan are to estimate the magnitude of the problem and identify the necessary human and material resources. This is to provide the Spanish Intensive Medicine Services with a tool to programme optimal response strategies.

Cytokine release syndrome. Reviewing a new entity in the intensive care unit

Immunotherapy seeks to harness the power of the immune system to eradicate malignant tissues. Despite impressive therapeutic success, however, it can be accompanied by severe adverse effects such as cytokine release syndrome (CRS). These therapies cause the release of a great amount of cytokines, with IL-6 playing a central role, that can potentially lead to multiple organ dysfunction. The diagnosis is based on the presence of compatible clinical symptoms, elevated biomarkers and recent treatment with a biological agent. Mild cases can be managed through symptomatic treatment and fluids, while more severe episodes may need supportive therapy and specific care with the anti-IL-6 receptor monoclonal antibody tocilizumab. Although corticosteroids are also effective, they suppress T-cell activity, and so should only be considered as second line therapy or in cases of severe neurological involvement, since tocilizumab does not cross the blood-brain barrier. Cytokine release syndrome generally has a good prognosis, often being reversible and with a good response to specific treatment. Despite possible concerns about the admission of such patients (mainly with advanced oncological disease), we consider that the Intensive Care Unit should remain an option, since these individuals present a potentially reversible drug-related adverse event and are being treated with a new drug that could change the prognosis of the disorder. Intensive care medicine will become a key component in the management of the complications of modern cancer therapies, dealing with patients presenting an overactive immune system producing organ dysfunction while also trying to maintain treatment efficacy. This is the new paradigm.

Albumin administration in the acutely ill: what is new and where next?

Albumin solutions have been used worldwide for the treatment of critically ill patients since they became commercially available in the 1940s. However, their use has become the subject of criticism and debate in more recent years. Importantly, all fluid solutions have potential benefits and drawbacks. Large multicenter randomized studies have provided valuable data regarding the safety of albumin solutions, and have begun to clarify which groups of patients are most likely to benefit from their use. However, many questions remain related to where exactly albumin fits within our fluid choices. Here, we briefly summarize some of the physiology and history of albumin use in intensive care before offering some evidence-based guidance for albumin use in critically ill patients.
