Patients with tracheobronchial disease frequently require mechanical ventilation during therapy and experience iatrogenic complications such as barotrauma and volutrauma. The purpose of this study was to determine whether perfluorocarbon-associated gas exchange (PAGE) results in lower ventilatory pressures and more efficient ventilation than that provided by conventional ventilation after tracheobronchial mucosal injury caused by smoke inhalation in neonatal piglets. Ten piglets were used for this prospective, randomized study. ⋯ Arterial blood gases showed significantly (P < .05) decreased pH, PO2, and elevated PcO2 levels in the control group past 12 hours after injury. The oxygenation index was significantly elevated (P < .05) in the control group past 12 hours after injury. PAGE shows potential for improving ventilation and survival immediately after severe smoke inhalation injury and may have clinical applications in other nonhomogeneous lung injuries.

A very rare case of a childhood bronchial mucoepidermoid tumor is presented. A 4-year-old girl was hospitalized with prolonged pneumonia. Computed tomography of the chest showed a tumor with calcifications in the right upper lobe. ⋯ Symptoms result from associated bronchial obstruction. Children with recurrent or prolonged pneumonia should undergo aggressive diagnostic investigation by chest tomography or bronchoscopy. Appropriate therapy for childhood bronchial mucoepidermoid tumor is total resection of the lesion while sacrificing as little of the normal lung tissue as possible.

Review Case Reports
Tracheal rupture after blunt chest trauma in a child.
Blunt traumatic tracheal rupture is a life-threatening injury. The authors report on a 14-year-old boy who suffered such an injury in a road accident, underwent surgery immediately, and survived. The relevant literature is reviewed.

Comparative Study
Childhood intussusception: ultrasound-guided Hartmann's solution hydrostatic reduction or barium enema reduction?
A comparison was made of the efficacy of ultrasound guided Hartmann's solution hydrostatic reduction on 23 patients (US group) with the same number of consecutive patients in whom hydrostatic reduction was done by barium enema (BE group) under fluoroscopy for childhood intussusception. The US group was diagnosed by ultrasound scan and reduction was attempted under the guidance of ultrasonography with Hartmann's solution at 100 mm Hg pressure. Excluded were patients older than 12 years, patients in shock, patients with peritonitis, bowel perforation, and gross abdominal distension as well as recurrent intussusception of more than three episodes. ⋯ The success rates for the ileo-colic intussusceptions with Hartmann's solution reduction and barium enema reduction were 91% (19 of 21) and 55% (12 of 22), respectively (P = .00865). There was no complication in either group, and the accuracy of diagnosing a complete reduction was 100% in both forms of reduction. Hence, ultrasound-guided hydrostatic reduction for childhood ileocolic intussusception is preferred because it is safe, accurate, has a higher success rate, and can avoid radiation exposure risk.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of continuous infusion of fentanyl to bolus dosing in neonates after surgery.
Concern about respiratory depression may lead to underuse of postoperative narcotic analgesia in neonates. The authors compared continuous infusion of fentanyl with bolus dosing in infants after surgery to determine whether continuous infusion is associated with less respiratory depression. ⋯ Continuous infusion of fentanyl at the doses studied is associated with pain control similar to that with bolus dosing at regular intervals. Although episodes of respiratory depression were less severe and less frequent for C patients, there may be an increased need for ventilator support with continuous infusion of fentanyl to achieve acceptable pain control. Providing adequate pain control to neonates in the immediate postoperative period remains a challenge.
