We have used flexible fibreoptic bronchoscopy using sedation and local anaesthesia in 50 children aged 2-19 years (median 10) using an Olympus BFP20 instrument. Indications were opportunistic pneumonias (n = 11), persistent atelectasis (n = 11), recurrent pneumonia (n = 7), miscellaneous lower airway disease (n = 7), recurrent wheezing (n = 3), haemoptysis (3), to diagnose infection or rejection of heart-lung transplants (n = 3), stridor (n = 2), suspected airway compression (n = 1), evaluation of tracheostomy (n = 1), and suspected foreign body (n = 1). In 43 cases (86%) the diagnosis was related to the primary indication. ⋯ Our results suggest that flexible fibreoptic bronchoscopy is safe. Advantages over rigid bronchoscopy include greater visual range, fewer complications, and the avoidance of a general anaesthetic. Though invasive it can yield important diagnostic and therapeutic information.

Randomized Controlled Trial Clinical Trial
Respiratory compliance in premature babies treated with artificial surfactant (ALEC).
In a randomised trial of artificial surfactant (ALEC) given at birth to 294 babies less than 34 weeks' gestation, the respiratory compliance was measured at 1, 6, 24, 48, and 168 hours after birth. In babies less than 29 weeks' gestation ALEC significantly improved the mean (SEM) compliance at 6 hours from 0.54 (0.06) to 0.91 (0.13) ml/cm H2O/kg and at 24 hours from 0.57 (0.04) to 0.92 (0.10) ml/cm H2O/kg. ⋯ In babies of over 29 weeks' gestation the compliance was lower in the ALEC treated babies. This was significant only at one hour: 0.52 (0.03) compared with 0.71 (0.07) ml/cm H2O/kg and only occurred in babies who were not ventilated.

Doppler echocardiograms were carried out on 51 healthy babies three times during the first 72 hours of life to estimate pulmonary arterial systolic pressure by measuring regurgitant tricuspid jet velocity and applying the Bernoulli equation. Tricuspid regurgitation was detected at some stage in all preterm babies and most of those born at full term. Pulmonary arterial pressure could be measured from peak regurgitant velocity in babies with pansystolic regurgitation. ⋯ The ratio of pulmonary:systemic arterial pressure was comparable between the two groups throughout. Ductal flow patterns mirrored the fall in this ratio with age--bidirectional flow was associated with a ratio of between 0.88:1 and 1.22:1 and high velocity left to right flow with a ratio of between 0.49:1 and 0.66:1. Both these techniques are noninvasive ways of assessing neonatal pulmonary arterial pressure.

Computer generated and dictated discharge summaries were compared for all 133 babies admitted for intensive and special care during a six month period. Whereas 130/133 (98%) had a computer generated summary, only 94/133 (71%) had a dictated summary. In addition, computerised summaries were completed at discharge, but there was a delay up to 26 weeks for dictated summaries. ⋯ A main diagnosis was missing in only 5/95 (5%) of dictated and 1/130 (1%) computerised summaries. Of the computer generated summaries, 114/133 (86%) were suitable to give to parents. Satisfactory discharge summaries for babies requiring intensive or special care can be generated with an on line computer system.
