| pubmed-article:1735398 | pubmed:abstractText | The hypnotic effects of thiopentone and ketamine were studied in ASA Grade I female patients aged 20-30 without premedication. The dose-response curves of ketamine 0.4 mg kg-1 and thiopentone following ketamine 0.4 mg kg-1 were determined by probit analysis. The interaction between ketamine and thiopentone was found to be an antagonistic one. This effect can be interpreted as a consequence of the different neurophysiological spectra of action of the two drugs. | lld:pubmed |
