Effect of the Position of the Patient's Head

Brain Lesion Clinical Trial

Official title: Study of the Effect of the Position of the Patient's Head With Brain Lesions on Cerebral Blood Flow

Status Completed

Clinical Trial Summary

The position of the head of the patient influences the cerebral venous return and cerebral perfusion pressure (CPP). In our daily practice, it is almost routine to prescribe a Trendelenburg position 30 ° in all brain-damaged patients. However, this is based only on precarious bibliographic databases. It has been shown to decrease the Intracranial Pressure (ICP) in Trendelenburg position relative to the horizontal, with varying effects on PPC. Effects on sylvian objectified by Doppler velocities and cerebral oxygenation seem unaffected by changes of position of the head of the patient. But the whole of the literature on this subject has significant bias.

Clinical Trial Description

Registration of blood flow changes induced when the patient's head will be tilted at 0 ° (that is to say flat), 15 ° and 30 ° (the order of actions will be determined by randomization). The patient will remain 10 minutes in each of these positions and will also have a little extra blood sample of 1 ml (ie 9 samples). These measures will be carried out again the next day and then after five days to see if the results vary depending on the evolution of his condition. ;
