Summary

A new “disposable inhaler for penthrane analgesia” (Abbott), the “Analgizer,” was used during labour and delivery in 14 unselected obstetric patients. Clinical evaluation demonstrated good to excellent pain relief without adverse effect on labour, maternal blood pressure or heart rate, foetal heart rate, or condition of the neonate at birth. Biochemical determination in twelve of the mothers and foetuses revealed oxygen tension, carbon dioxide tension, pH, and base deficit values within the normal ranges.

The Analgizer was found to offer four advantages. It is small and lightweight. It is versatile in that it can be used with or without a face mask and with its built-in “diluter hole” open or closed. In addition, it is disposable, thus preventing cross-contamination.

RéSUMé

Chez quatorze malades en train d’accoucher, malades non choisies, nous avons employé le nouveau vaporisateur à usage unique (Abbott) pour l’analgésie au penthrane “l’insensibilisateur”. L’évaluation cHnique de l’analgésie obtenue a donné des résultats allant de bons à excellents, sans effet nuisible sur le travail, la pression sanguine ou le pouls maternel, le cceur fétal ou l’état du bébé à la naissance. Chez douze de ces méres et leurs enfants, les examens biochimiques ont donné des valeurs normales de laPo2, de laPoc2, du pH et des bicarbonates.

A notre avis, cet “insensibilisateur” présente quatre avantages: il est petit et 1éger; il est souple; il peut s’employer avec ou sans masque sur la figure de la malade et sa prise d’air peut être ouverte ou fermée. Enfin, son usage unique évite le transport de l’infection d’une malade à l’autre.
