[Influence of preanesthetic medication on the effect of a local anesthetic tape].
We investigated the influence of preanesthetic medication on the pain relieving effect of the lidocaine tape during needle insertion for venous cannulation. Ninety patients scheduled for elective surgery were randomly divided into three groups of 30 each; patients without preanesthetic medication (group N), patients who received 0.1 mg.kg-1 of diazepam (group D) and 5 micrograms.kg-1 of clonidine (group C) as a preanesthetic medication. Ninety minutes before the induction of anesthesia, we applied a lidocaine tape to each patient. The grade of pain at the pinprick test and at the venous puncture was evaluated in the operating room. No significant difference of the pain score was seen between the groups. We concluded that the effect of lidocaine tape was not influenced by the preanesthetic medication.
