[Transcutaneous trinitrine. Calling into question the efficacy and innocousness of its use in facilitating venous approach].

Seven infants aged 6 days to 9 months were tested for the use by rubbing of a pomade containing 1 mg trinitrine. The study was interrupted because of high blood passage of trinitrine. The authors emphasize the difficulty of any comparison with the use of this drug in adults. They indicate that there was no clinically appreciable side-effect but they advise to delay, until further studies, the use of this technique, with the only objective of improving the technique of intravenous injections or sampling.
