Brief Summary:
The purpose of this trial is to study the effect of initial temporary sevoflurane sedation on mortality and persistent organ dysfunction (POD) in survivors at day 28 after ICU admission in the population of patients suffering from COVID-19 ARDS.

Condition or disease Intervention/treatment Phase
ARDS, Human Coronavirus Drug: Sevoflurane Drug: Intravenous drug Phase 3

Detailed Description:

The corona virus disease 19 (COVID-19) pandemic, caused by the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), is spreading rapidly across Europe. While data from European centers are still missing, several publications from Chinese centers are available. Respiratory failure from acute respiratory distress syndrome (ARDS) is the leading cause of mortality, and may be caused or exacerbated by a 'cytokine storm syndrome'.

Recent trials from our group demonstrated that the volatile anesthetic sevoflurane administered during ventilation of patients has anti-inflammatory properties. Moreover, in in vivo studies volatile anesthetics reduce the severity of ARDS compared to intravenous sedation, which has been confirmed in a clinical pilot trial. Attenuating ARDS and thereby improving oxygenation strongly decreases morbidity and mortality of patients.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 64 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: a randomized, controlled multi-center trial
Masking: Double (Participant, Outcomes Assessor)
Masking Description: Patients will not be informed about their group assignments, technicians processing the samples will not have any access to the ICU or the patient chart (= double-blind trial). Due to the procedures involved in volatile versus intravenous sedation, group assignment cannot be entirely concealed for the study staff and ICU doctors/nurses involved with the procedure in the ICU (pragmatic limits of blinding).
Primary Purpose: Treatment
Official Title: Sevoflurane Sedation in COVID-19 ARDS Patients to Reduce Lung Injury: a Randomized Controlled Trial
Actual Study Start Date : April 23, 2020
Estimated Primary Completion Date : March 31, 2022
Estimated Study Completion Date : March 31, 2022

Arm Intervention/treatment
Experimental: Sevoflurane Sedation
Sedation with sevoflurane (etSevo 0.5-1.5 Vol %) for 48 hours in patients with COVID-19 ARDS
Drug: Sevoflurane
Sedation with sevoflurane (etSevo 0.5-1.5 Vol %) for 48 hours in patients with COVID-19 ARDS

Active Comparator: Intravenous
No use of sevoflurane, but current intravenous sedation at discretion of the ICU physician in charge, e.g. with propofol, fentanyl, midazolam and dexmedetomidine
Drug: Intravenous drug
Intravenous sedation in control group will be continued as initiated at the ICU e.g. propofol, fentanyl, midazolam, dexmedetomidine

Primary Outcome Measures :
  1. Composite outcome of death rate (rate of patients that did not survive) and organ failure rate (rate of patients surviving with persistent organ dysfunction) at day 28 [ Time Frame: 28 days ]
    The effect of sevoflurane application on mortality (rate of patients that does not survive 28 days) and persistent organ dysfunction (rate of patients surviving with a persistent organ failure at day 28) will be assessed. Organ failures are defined as pulmonary failure (necessity of ventilation); cardiovascular failure (need of vasopressors), retail failure (need of renal replacement therapy)

Secondary Outcome Measures :
  1. Length of stay ICU [ Time Frame: 28 days ]
    The effect of sevoflurane application on the length of stay at ICU will be determined.

  2. Plasma Inflammatory markers [ Time Frame: 8 days ]
    The impact of sevoflurane on the course of inflammatory markers will be evaluated (pro-calcitonin, PCT; c-reactive protein, CRP; interleukin 6, IL-6; monocyte chemoattractant protein 1, MCP-1)

  3. Length of stay at hospital [ Time Frame: 28 days ]
    The effect of sevoflurane application on the length of stay at hospital will be determined.

  4. Sex-related differences in complications [ Time Frame: 28 days ]
    Sex-related differences in complications will be assessed
