Abstract
The measurement of plasma fentanyl concentration by radioimmunoassay (RIA) and gas liquid chromatography (GLC) using either aflame ionization detector (FID) or nitrogen/phosphorus detector (NPD) has been compared. RIA is asatisfactory but expensive method of measuring plasma fentanyl concentration. GLC using an FID is not as satisfactory as RIA, but when an NPD is used the results are equal to those of RIA. In addition, other analgesics which are chemically similar to fentanyl, such as alfentanil, may also be measured by the GLC/ NPD combination using the same set of operating conditions. By contrast, an RIA method is usually specific for only one compound, and measurement of additional drugs would almost certainly necessitate the development of new assay kits for each one. On acomparé la technique pour mesurer la concentration du fentanyl dans le plasmapar la méathode radio-immunologique (RIA) et la chromatographie en phase gazeuse liquide (GLC) en se servant soit d’une flamme d’ionisation détectrice (FID), soit d’un détecteur d’azote-phosphore (NPD). La méthode RIA est satisfaisante mais coûteuse pour mesurer la concentration du fentanyl dans le plasma, La méthode GLC utilisée avec la FID n’est pas aussi efficace que la méthode RIA, mais si l’on utilise le NPD on obtient les mêmes résultats qu’avec la méthode RIA. De plus, d’autres analgésiques qui sont similaires chimiquement au fentanyl, tel que l’alfentanil, peuvent aussi être mesurés en utilisant le méme genre de technique. Par contre, une méthode RIA est généralement spécifique pour un seul agent. Si l’on voulait mesurer des drogues additionnelles, chaque agent nécessiterait presque le développement d’une trousse d’essay.Keywords
