About this study
Official title: The Correlation of Regional Cerebral Oxygen Saturation(rScO2) Variation in Passive Leg Raising (PLR) With Neurological Outcomes of Sepsis and Septic Shock Patients
Sepsis related cerebral dysfunction was underestimated in critical illness setting, and inflammatory response of brain could not be monitored directly and cerebral oximetry offered information of cerebral dysfunction. We had hypothesized cerebral oxygenation responsiveness during passive leg raising could in some way had association in predicting with the outcomes of septic shock.
Read the detailed description
Research question: Does increased regional cerebral oxygen saturation variation in passive leg raising(PLR) associated with better neurological outcomes of sepsis and septic shock patients?
Specific aims:
- To stablish an algorithm to assess focal neurological dysfunction through regional cerebral oxygen saturation(rScO2) of sepsis and septic shock patients
- To assess the safety and gain some experiences evaluate cerebral oxygen in passive leg raising and fluid expansion.
- To test the correlation of rScO2 variation with neurological complication and prognosis of septic shock patients.
Significance:
- Sepsis and septic shock were associated with increased risk of mortality, elevated morbidity rates, and neuro-developmental disability.
- The definition of SEPSIS 3.0, signify qSOFA scores as a bedside prompt that may identify patients with suspected infection who are at greater risk for a poor outcome, It uses three criteria, including altered mentation (Glasgow coma scale<15).
- Previously, sepsis related cerebral dysfunction was underestimated in critical illness setting, and inflammatory response of brain, such as oxygen deficit of brain tissue could not be monitored directly, thus cerebral oximetry monitoring could be used for the evaluation of cerebral tissue oxygenation in real time, providing indirect information of the brain function during sepsis and septic shock.
- Length of reduced cerebral oxygen saturation was confirmed associated with worse outcome after major surgery perioperatively. We hypothesized that cerebral oxygen metabolism was degenerated during sepsis and septic shock, and lower cerebral oxygenation would have somewhat correlations with worse outcome of sepsis and septic shock patients.
Study Design： This will be a observational cohort trial. The schematic diagram of the study is as Figure 1. Subjects will be enrolled, and then be followed up. The outcome variables will be recorded. Inclusion criteria were age above 18 either under 80 years, and diagnosed with sepsis, using Sepsis 3.0 criteria.
Whereas exclusion criteria were patients who were under 18 or above 80 years, pregnant, brain dead, severe head trauma, patients who had a difference more than 10% between the 2 probes of cerebral oxygen saturation monitor due to possible unilateral focal pathology, and whose cousins made decision to withdraw from resuscitation.
The baseline parameters of sepsis and septic shock patients are collected: demographic data (age, sex, comorbidities, resources and diagnosis), Acute Physiology and Chronic Health Evaluation (APACHE) II score (on admission and after 24 hours), hemo-dynamic parameters (mean arterial pressure [MAP], heart rate, cardiac index [CI], stroke volume variation, and global end-diastolic index using PICCO Monitor from Pulsion, Germany), serial lactic acid measurements at presentation and after 48 hours, blood gases (arterial and central venous [at presentation and every 8 hours]), and rScO2 (at presentation and every 8 hours). Delirium were diagnosed using CAM-ICU criteria for delirium in ICU.

What is being measured
The primary outcome is the main question the study is designed to answer.
Deilirium
Delirium, also known as acute confusional state, is an organically caused decline from a previously baseline level of mental function.It typically involves other cognitive deficits, changes in arousal (hyperactive, hypoactive, or mixed), perceptual deficits, altered sleep-wake cycle, and psychotic features such as hallucinations and delusions. Our every patient gets checked for delirium every day (usually twice or more a day) using a validated clinical tool of Confusion Assessment Method for the ICU (CAM-ICU).The first step to assessing consciousness is to assess level of consciousness.The next step is assessment of content of consciousness. Think: rapid onset, inattention, clouded consciousness (bewildered), fluctuating.

Questions about this trial
What is this clinical trial studying?
An observational study of Critical Illness and Sepsis, run by Peking Union Medical College Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 May 2018. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Deilirium (time frame: 7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03523169, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2018.
