[EMLA for anesthesia of puncture sites for large lumen indwelling venous catheters for autologous plasma and erythrocyte concentrate donation].
OBJECTIVE
The analgetic effect of EMLA-Creme (Lidocaine-Prilocaine-Cream) was studied in 52 patients undergoing preoperative autologous blood and/or plasma donation.


METHODS
95 venous punctures were performed with a 18 G or 16 G cannula. Puncture pain was estimated by the patients using a visual analog painscore (VAS 0-100). The data were evaluated regarding reaction time, puncture spot and cannula diameter.


RESULTS
Within 15 minutes we find a clear reduction of puncture pain. The diameter of the cannula does not correlate with the painscore. Puncture of hand-back veins seems to be more painful than cubital vein puncture.


CONCLUSIONS
The application of EMLA-Creme results in an effective analgesia for venous puncture. 37% of our patients were punctured without any pain and 67% felt a tolerable pain (VAS: 0-10).
