Near-infrared Vision for Microcirculatory Status

NCT04399811 | Unknown

• 1 other identifier: B2020-057R
• Study Type: observational
• Target: 2,000
• Locations: 0 countries
• Sites: N/A

Brief Summary

The investigators aimed to combine the image of near-infrared vision and machine learning method to evaluate the microcirculatory status of critical ill patients.

Conditions

Near-infrared Vision; Machine Learning; Microcirculatory Status

Outcome Measures

Primary Outcomes (1)

• Hospital mortality

  The rate of patients who died during hospital stay.

  From date of admission to our ICU until the date of hospital discharge or date of death from any cause, whichever came first, assessed up to 2 months.

Secondary Outcomes (2)

• Lacteta clearance rate

  When the near-infrared image is taken for a patient, the blood gas analysis will be performed immediately to get the value of lactate. After 2-hours, another blood gas analysis will be conducted to get the second value of lactete.

• Capillary refill time (CRT)

  When the near-infrared image is taken for a patient, the capillary refill time will be measured immediately.

Interventions

Near-infrared Vision Photograph DIAGNOSTIC_TEST

The near-infrared image will be recorded (by a infrared camera connected to a laptop) for each enrolled patient
