Comparative Study
Tongue oximetry in children with extensive thermal injury: comparison with peripheral oximetry.
We undertook a prospective study of standard peripheral pulse oximetry versus a modified pulse oximeter probe applied to the tongue in order to determine the efficacy of this alternative monitoring site in children with thermal injuries. Ten patients with a mean age (+/- SD) of 7.5 +/- 4.5 yr were studied on 15 occasions. The mean weight (+/- SD) was 31.4 +/- 13.7 kg and percent surface area burn (+/- SD) was 56 +/- 21%. ⋯ The tongue oximeter provided 563 min more monitoring time than the peripheral sites. The tongue oximeter also functioned in children with peripheral vasoconstriction when the peripheral sensor failed and was less susceptible to electrocautery interference. The tongue oximeter is a reasonable adjunct but not a substitute for peripheral oximetry since its application is limited to paralyzed, intubated patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Adequacy of caudal analgesia in children after penoscrotal and inguinal surgery using 0.5 or 1.0 ml.kg-1 bupivacaine 0.125%.
To determine the optimal volume of bupivacaine 0.125% for postoperative caudal analgesia, we compared the effectiveness of 0.5 ml.kg-1 and 1 ml.kg-1 of bupivacaine 0.125% with 1:200,000 epinephrine in 80 children undergoing penoscrotal and inguinal surgery. The adequacy of caudal analgesia and supplemental analgesic requirements did not differ between the two groups at any time during the first 12 hr after surgery. We conclude that 0.5 ml.kg-1 of bupivacaine 0.125% with 1:200,000 epinephrine is as effective as 1 ml.kg-1 of the same solution and recommend its use for penoscrotal surgery. The evidence for effectiveness of 0.5 ml.kg-1 of bupivacaine 0.125% for inguinal surgery, however, is inconclusive because of an insufficient number of patients studied.

There have been many recent advances in the understanding and therapy of respiratory diseases. This review has attempted to cover some of the relevant new information about those disorders most likely to be encountered by anaesthetists. RéSUMé: Il y a de nombreux progrès récents dans la compréhension et la thérapie des maladies respiratoires. Cette revue a tenté de revoir l'information nouvelle et pertinente concernant les maladies les plus susceptibles d'être rencontrées par les anesthésistes.
