Randomized Controlled Trial Clinical Trial
[Postoperative analgesia in children after hernioplasty. Wound infiltration with different concentrations of bupivacaine: a pilot study].
Wound instillation seems to be an easy and preferable way to achieve postoperative analgesia in pediatric hernioplasty. This prospective, randomized and double-blinded pilot-study was initiated to gain preliminary information in order to define the appropriate concentration of local anaesthetic for efficient posthernioplastic analgesia. ⋯ Wound instillation with 0.2 ml of bupivacaine 0.5% seems to be easy to perform, safe and efficient in controlling posthernioplastic pain. Because of the small numbers of patients included however, no statistically significant differences were observed between the groups. Neither in the LAPS on arrival and observation at the PACU nor in the need for supplementary analgesics. Despite lacking significance the clinical impression suggests a difference to be validated by larger studies. Our data implies that wound instillation with 0.2 ml/kg bupivacaine 0.5% should be regarded for routine usage.
