Pc. Chang et al., A MULTICENTER RANDOMIZED STUDY OF SINGLE-UNIT DOSE PACKAGE OF EMLA PATCH VS EMLA 5-PERCENT CREAM FOR VENIPUNCTURE IN CHILDREN, Canadian journal of anaesthesia, 41(1), 1994, pp. 59-63
Eutectic mixture of local anaesthetics (EMLA) cream with Tegaderm was
compared with pre-packaged EMLA patch with regard to analgesic effect,
adhesiveness and local reactions during venepuncture in 178 children
from three to ten years. One EMLA patch, or half the contents of a 5 g
tube of EMLA cream plus Tegaderm was applied to the dorsum of one han
d or antecubital fossa for a minimum of 60 min before venepuncture. Th
e subject and observer assessed the degree of pain on a three-point ve
rbal rating scale. The adhesion of the patch vs Tegaderm to the skin a
nd local reactions were recorded. There was no difference between the
two groups in pain associated with venepuncture; 95% of the EMLA patch
group and 94% of the EMLA cream group reported no or slight pain. The
re was no difference between the two treatment groups in terms of over
all local reactions. The patch was less adhesive (P < 0.001), but this
had no apparent influence on its effectiveness. In conclusion, EMLA p
atch is equivalent to 5% EMLA cream (2.5 g) in cutaneous pain relief w
hen used for venepuncture in children.
