Comparative StudyComparison of regional vs systemic analgesia for post-thoracotomy care in infants.
In infants, post-thoracotomy analgesia traditionally consists of systemic opiates, while regional techniques have gained more favor in recent years. We compare the two techniques for thoracotomy in infants. ⋯ In infants undergoing thoracotomy, loco-regional analgesia is effective and associated with a reduced intensity of postoperative care and earlier full feeding than systemic analgesia; it should therefore be considered a better option.

The pharmacokinetics of methadone and its metabolites in neonates, infants, and children.
The lack of methadone pharmacokinetic data in children and neonates restrains dosing to achieve the target concentration in these populations. A minimum effective analgesic concentration of methadone in opioid naïve adults is 0.058 mg·l(-1) , while no withdrawal symptoms were observed in neonates suffering opioid withdrawal if plasma concentrations of methadone were above 0.06 mg·l(-1) . The racemate of methadone which is commonly used in pediatric and anesthetic care is metabolized to 2-ethylidine-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) and 2-ethyl-5-methyl-3,3-diphenylpyrroline (EMDP). ⋯ Current pharmacokinetic parameter estimates in children and neonates are similar to those reported in adults. There was no clearance maturation with age. Neonatal enantiomer clearances were similar to those described in adults. A regimen of 0.2 mg·kg(-1) per 8 h in neonates achieves a target concentration of 0.06 mg·l(-1) within 36 h. Infusion, rather than intermittent dosing, should be considered if this target is to be achieved in older children after cardiac surgery.

Case ReportsTransient abdominal wall deformity in an infant Blaming the caudal?
Locoregional anesthesia is an important aspect of perioperative analgesia. It decreases requirements for anesthetic agents and opioids, decreases the surgical stress response, and provides postoperative analgesia. Nonetheless, pediatric patients, especially infants, demonstrate specificities towards regional anesthesia techniques, as an increased sensitivity to local anesthetics (LA) and a higher ease of LA spread especially when using blocks that rely on the volume of LA and its spread as those used for abdominal wall analgesia or caudal. Thus, we present a case of transient abdominal wall deformity following caudal anesthesia in an infant.

Use and reimbursement of off-label drugs in pediatric anesthesia: the Italian experience.
Most of the drugs used in anesthesia are off-label in children even if they present solid clinical evidence in adults. This lack of authorization is caused by multiple factors including the difficulty in conducting research in this area (due to the ethical concerns and/or the low number of available participants, the high variability of the outcome measures) and the lack of economic interest of the pharmaceutical companies (due to the limited market). ⋯ Continuous efforts are needed from government institutions and sponsors on drug development and on drug approval process in pediatrics, as research on drug effectiveness and safety is mandatory in children as in adults. At the same time, clinicians must become more familiar with the drug-approval process, participate to sponsored trials, and perform ztrials themselves.
