Brief Summary

Capillary refill time is the time it takes for the skin to regain its initial colour after moderate pressure. It is usually performed on the patient index finger, middle finger or ring finger with the examiner's thumb and index finger for five seconds, three measurements having to be averaged. Capillary refill time has a dependent operator character, but it has been shown to be accurately correlated with 14-day mortality in septic shock, hospitalisation need in pediatric population. The purpose of this project is to show that capillary refill time obtained by a video-assisted method has a better inter- and intra-observer reproducibility than capillary refill time obtained by a visual method.

Interventions

time of cutaneous recoloration OTHER

In the shortest time possible (less than 3 minutes), realization of three successive measurements of the time of cutaneous recoloration by a pressure by the so-called visual method by two intensivists trained at the CRT of the surgical resuscitation service familiar with the technique of time of cutaneous recoloration. The measurements will be carried out blindly from each other.

video assisted cutaneous recoloration OTHER

Compression of the nail bed of the index of the subject studied until whitening of the pressed area, then release, the force will be equivalent to 300 g on a kitchen scale TPA 808S Techwood™ and time of compressions being of 5 seconds. Smartphone camera recording of the procedure (Iphone 7™, Apple Inc., Cupertino, CA). An assistant is in charge of timing the TRC between two "tops" given by the operator, the tops corresponding to the release of the pressure on the index so the beginning of the TRC and the total recoloration of the bleached area. This wizard records the three results in seconds with the associated tenth of a second.
