A Comparison of Inactin and Thiopentone as Intravenous Anaesthetics

Further Experiences With Methylated Thiobarbiturates

“…Since grade 3 anaesthesia (classification of Dundee and Riding, 1960) indicates that the administration was either totally unsatisfactory from the surgeon's point of view or dangerous to the patient, it can be seen that the methylated thiobarbiturates are unsatisfactory for clinical use. From our experience with these compounds, together with that of Stoelting (1953), it would seem that the methylated thiobarbiturates are unlikely to have any place in anaesthetic practice.…”
