[Sixty percent lidocaine tape alleviates pain on injection of propofol after diminishing venipuncture pain].
We evaluated the efficacy of the 60% lidocaine tape in alleviating pain associated with intravenous propofol administration in 71 gynecological patients. Thirty-eight women had the tape applied for 2.5 h before venipuncture, with the remaining patients acting as the control. A 20 gauge cannula was inserted into the cephalic vein. Propofol at room temperature was injected at a rate of 1200 ml.hr-1. The statistical significance of differences was established with the Mann-Whitney's U test and the chi 2 test. The median level of pain intensity resulting from venipuncture among the patients treated with the tape was smaller than that in the control group (16.5, vs 34, P = 0.006). Thereafter, cannulation was successfully achieved with reduced or no pain (VAS at cannulation < or = 25, n = 39), and only 16% of the treatment group complained of pain on injection as compared with 53.8% of the control group (P = 0.02). Moreover, the pain intensity was decreased with lidocaine tape (P = 0.006). The cost of the lidocaine tape is covered by medical insurance for reducing pain on venipuncture. Thus, as the tape also alleviates the pain on injection of propofol through its anesthetic action, it can be a safe, easy and cost-effective method as "it kills two pains with one tape".
