ABSTRACT
Our objective was to determine the most reliable site for temperature measurement in children. In anesthetized children esophageal temperature readings were closest to those in the pulmonary artery (mean difference 0.1 degree C +/- 0.5 degree C compared with Genius tympanic thermometer (mean difference 0.6 degree C +/- 1.0 degree C), IVAC tympanic thermometer (mean difference 0.8 degree C +/- 1.0 degree C), rectal probe (mean difference 0.7 degree C +/- 1.7 degrees C), bladder probe (mean difference 0.9 degree C +/- 1.4 degrees C), and axillary probe (mean difference 1.3 degrees C +/- 1.3 degrees C).

BACKGROUND: Aprotinin use in adults is increasing, and its use in children has recently been reported. METHODS: The efficacy of aprotinin in children was tested in 80 children. Patients were in four groups: reoperations (59), neonates (8), extremely cyanotic children (6), and other complex repairs (7). The results were compared with those of 55 control infants and children: reoperations (25), neonates (10), cyanotic (10) and complex (10). Treatment groups were identical in age, sex ratio, cross-clamp time, and bypass time. RESULTS: Patients treated with aprotinin had a significant reduction in chest tube drainage (16.5 +/- 9.8 versus 33.4 +/- 22.1 mL.kg-1.h-1; p < 0.001) and time to skin closure (64.2 +/- 23.7 versus 80.1 +/- 24.6 minutes; p < 0.001). Transfusion requirements were decreased in aprotinin-treated patients 4.2 +/- 3.4 versus 6.7 +/- 5.2 donors; p < 0.001). All of the control patients were exposed to at least one donor, whereas 10/80 (12.5%) of the aprotinin-treated group had no blood use (p < 0.006). There were no cases of renal insufficiency or allergic reactions in children receiving aprotinin. Three patients had thrombotic episodes: 2 superior vena caval problems and a lower extremity deep venous thrombosis. There were 3 cases of mediastinitis in the aprotinin group versus none in control patients (p < 0.05). CONCLUSIONS: We conclude aprotinin is an effective means of reducing bleeding, operating time, and donor exposure in infants and children. An increased rate of thrombosis and possibly mediastinitis are potential problems.

BACKGROUND: For a newborn requiring positive-pressure ventilation (PPV), the American Heart Association recommends bag-and-mask ventilation, a challenging procedure for those inexperienced in neonatal resuscitation. The objective of this prospective study was to evaluate the laryngeal mask airway (LMA) as an alternative method of airway management in neonates requiring PPV at birth. METHODS: With the approval of the institutional ethics committee, consent was obtained from women in labor at a tertiary care-perinatal center. Inclusion criteria consisted of an expected birth weight of at least 2.5 kg, gestational age of at least 35 weeks, and resuscitation requiring PPV. Neonates meeting these criteria were resuscitated with PPV by means of the LMA. The ease of insertion, number of attempts required, time to establish effective ventilation, skin color, heart rate, respiratory effort, and Apgar scores were recorded. RESULTS: Attendance by the investigators at delivery was achieved in 93 cases, with 21 meeting the inclusion criteria. In all cases, the LMA was successfully inserted on the first attempt and provided a clinically patent airway. Twenty neonates were successfully resuscitated with the LMA to provide PPV, with no complications directly attributable to its use. One neonate required LMA removal and tracheal intubation to facilitate administration of epinephrine; data from this case was removed from the study. CONCLUSIONS: Providing PPV at birth via a size-1 LMA is effective and easily learned by personnel with expertise in neonatal resuscitation. The LMA should be further assessed as an alternative to bag-and-mask ventilation for this purpose.
