Sorption of chlormethiazole by intravenous infusion giving sets.
The sorption of chlormethiazole by intravenous infusion giving sets was investigated. Average recoveries of chlormethiazole following 500 ml infusions were 78.5%, 82.2% and 71.2% for the IVAC Volume Infusion Set, Travenol Code AHC 2890 Blood Administration Set and the McGaw Metriset, respectively. The effluent concentration-time profile using set up procedures and infusion rates similar to those used clinically were followed. When compared to solutions flowing at an infusion rate of 75 and 150 ml/h, loss of chlormethiazole from solutions standing static in the infusion sets was higher while that of solutions flowing at a high rate of 999 ml/h was lower. The clinical and pharmacokinetic significance of these phenomena are discussed.
