Observation of the correlation of postanaesthesia recovery scores with early postoperative hypoxaemia in children.
To observe the correlation of the postanaesthesia recovery score (PARS) with the incidence, and severity of early postoperative hypoxaemia in children, 1213 infants and children, ASA physical status I, aged three months to 14 years, scheduled for elective plastic surgery were included in this study. Arterial oxygen saturation (Spo2) levels were recorded while children were breathing room air shortly after arrival in the recovery room (0 min), and 5, 10, 15, 20, 30, 40, 50, 60, 120 and 180 min thereafter. The PARS was also determined on all patients when Spo2 levels were recorded in the recovery room. ⋯ There were significant differences among the three groups. Of the 91 children who required O2 supplementation in the recovery room because of low measured Spo2, 69 had the PARS of < or = 6, and 22 had the PARS of 7-8. It is concluded that if a patient has a PARS of 10, the patient will not need routine oxygen supplement because hypoxaemia will not occur.

Randomized Controlled Trial Comparative Study Clinical TrialPatient controlled analgesia in children and adolescents: a randomized controlled trial.
In children, patient controlled analgesia (PCA) and continuous infusion (CI) of morphine are well established methods of relieving postoperative pain. This study was designed to assess the efficacy of PCA plus background infusion (BI) (15 microg x kg(-1) x h(-1) and bolus doses of 15 microg x kg(-1) with a lock-out interval of 10 min) with CI (20 to 40 microg x kg(-1) x h(-1)) in terms of analgesia, morphine needs and side-effects. A stratified randomized controlled trial was carried out. 47 children aged 5-18 years undergoing major elective lower/upper abdominal or spinal surgery were allocated. ⋯ Morphine consumption was significantly increased in the PCA group compared with the CI group. Moreover, morphine consumption was associated with SSS, independent of the technique of administration. There were no significant differences between groups in pain scores or in the incidence of side-effects.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of sevoflurane anaesthesia on recovery in children: a comparison with halothane.
We prospectively studied one hundred ASA physical status I-II children, ages six months to six years, undergoing myringotomy surgery. Children were randomly assigned to one of four anaesthetic groups receiving either halothane or sevoflurane for anaesthesia and oral midazolam premedication or no premedication. We found that children anaesthetized with sevoflurane had significantly faster recovery times and discharge home times than those who received halothane. ⋯ However, children anaesthetized with sevoflurane and no premedication had an unacceptably high incidence (67%) of postoperative agitation. The use of oral midazolam preoperatively did decrease the amount of postoperative agitation seen with sevoflurane. We conclude that although sevoflurane does shorten recovery times, the degree of associated postoperative agitation makes it unacceptable as a sole anaesthetic for myringotomy surgery.

Randomized Controlled Trial Comparative Study Clinical TrialRopivacaine 0.25% compared with bupivacaine 0.25% by the caudal route.
We compared in a randomized double-blind study, the postoperative analgesia and degree of motor block produced by the new local anaesthetic ropivacaine, with bupivacaine, for caudal anaesthesia in children. Eighty children, 2-5-years-old, ASA I, received one of two local anaesthetics; either ropivacaine 0.25% (1.0 ml x kg(-1)) or bupivacaine 0.25% (1.0 ml x kg(-1)). They were sedated with a continuous infusion of propofol (200 microg x kg(-1) min(-1). ⋯ The ropivacaine group showed a shorter duration of motor block than the bupivacaine group (P<0.05). The first postoperative analgesic requirement was a mean (sd) of 5 h+/-4.32 after the operation in the ropivacaine group and 5 h+/-3.81 for the bupivacaine group. These findings suggest that caudal anaesthesia with ropivacaine 0.25% in paediatric patients can be effective, with less motor blockade in the postoperative period.
