[Cerebrospinal fluid transfer of cefotiam (CTM). Its relationship to CT].

Drip intravenous infusion of cefotiam (CTM) was made on patients who underwent cerebrospinal fluid (CSF) drainage and study was made on CSF transfer of CTM and at the same time on the relationship between CSF transfer of iodine contrast medium and CT scan findings. This study was made on 11 cases of cisternal drainage and 8 cases of ventricular drainage. Cisternal drainage cases were all postoperative cases of ruptured cerebral aneurysm. Cases of ventricular drainage included 4 postoperative cases of ruptured cerebral aneurysm, 1 case of CSF rhinorrhea, 2 cases of brain tumor, and 1 case of ventricular hemorrhage. Drip intravenous infusion of 1.0 g of CTM was made in one hour and at given periods thereafter CSF was collected and measured. CTM transferred to the CSF in cistern at a comparatively high concentration (16.3-0.7 microgram/ml). Hardly any transfer of CTM to the CSF in ventricle was seen in one case of cerebral aneurysm, CSF rhinorrhea, and brain tumor, but transfer was observed in one case of cerebral aneurysm, one case of brain tumor, and case of ventricular hemorrhage. Transfer of iodine contrast medium showed the positive correlation to the transfer of CTM. In cases of brain tumor and ventricular hemorrhage with transfer of CTM with ventricular drainage, enhancement effect of the ventricular wall by the contrast medium could be observed by CT scan. From the foregoing, the following results were obtained. There was good transfer of CTM to the CSF in cistern in postoperative cases of ruptured aneurysm. CTM did not transfer to CSF in the normal ventricle.(ABSTRACT TRUNCATED AT 250 WORDS)
