Aspiration and regurgitation prophylaxis in paediatric anaesthesia.
Surveys of aspiration prophylaxis in paediatric anaesthesia do not exist. ⋯ Perceived risk factors vary with "experience": hiatus hernia, difficult intubation and cerebral palsy are less important whereas previous aspiration and renal failure appear to be more important for paediatric anaesthetists with less than 10 years in paediatric anaesthetic practice.

Randomized Controlled Trial Comparative Study Clinical TrialMorphine with or without a local anaesthetic for postoperative intrathecal pain treatment after selective dorsal rhizotomy in children.
Selective dorsal rhizotomy is a surgical procedure with a selective division of posterior spinal nerve rootlets to treat spasticity in children. The extensive surgical procedure with multilevel laminectomies and the nerve root manipulation result in intense pain postoperatively. Two intrathecal (IT) regimes of pain treatment were compared in these children, concerning their pain relief and possible side-effects. ⋯ Bupivacaine/morphine resulted in a lower, but not significant, difference in pruritus and lower muscle spasm. Haemodynamic and ventilatory parameters did not differ between the groups. Intrathecal continuous infusion of bupivacaine and morphine was superior to intermittent morphine in the treatment of pain after selective dorsal rhizotomy operations.

The pressures exerted on fragile structures in the infant during epidural injections have never been studied previously. ⋯ The residual pressures seem to vary more with the volume injected than the rate of injection or the pressures developed during the injection. The relationship between the rate of injection and pressures is significant when compared with adults where the pressures have been measured after an injection rate of 1 ml.s(-1) and 1 ml.5 s(-1). This is a very fast rate compared with our rates of injection of 1 ml over 1 and 2 min. Based on the findings of this study, we recommend a rate of 1 ml.2 min(-1) in infants. In neonates, a slower rate of injection would be preferable.
