There is a report that in the case of patients in the acute stage of cerebrovascular disorders, the compression of the upper arm for measuring blood pressure may affect cerebrospinal fluid CSF) pressure. This was studied in the patients in the acute stage of cerebral hemorrhage (or infarction. The results obtained were as follows.
1) In 10% of the patients, CSF pressure increased when usual hemodynamometry was performed, but the increase was slight.
2) The upper arm was compressed nine times. Each time thecompression was relieved before the next compression started. The pressure applied was increased each time (60-220 mmHg). Through this procedure, that is, the repeated compression, the incidence of the increase of CSF pressure increased. In the case of controls, the increase occurred in 92.1% of trials; in the case of cerebrovascular disorders including both acuteand chronic stages, 69.1% ; in the case of the acute stage of the cerebrovascular, disorders 47.8%.
3) It was considered that the pain caused by the compression induced an increase in CSF pressure via the sympathetic nervous system.
4) Judging from the above results, it may be concluded that there is almost no effect of the upper arm compression on CSF pressure in patients in the acute stage of cerebrovascular disorders, but it had better avoid to repeat upper arm compression.
