The authors report the use of Ramathibodi External ventricular drainage ( EVD ) collecting device. It is made of previously-used medical items. The device costs 100 baht, compared to over 3,000 baht for those commercially available in Thailand. Over two hundred RAMA EVD collecting devices have been used with neurosurgical patients since 2002. Accurate cerebrospinal fluid ( CSF ) output measurement can be made with this device. Intracranial pressure monitoring is also possible. Because it is inexpensive and can be easily assembled, the authors recommend the RAMA EVD collecting device uses to other hospitals in Thailand.
