ABSTRACT
Pneumatoceles due to acquired localized overinflation as a form of pulmonary interstitial emphysema are complications of advanced bronchopulmonary dysplasia. Different ventilation modes, selective bronchial intubation, balloon obstruction of the affected bronchus and steroids have been reported with success. Lobectomy has also been used. We present a premature infant with multiple large pneumatoceles causing respiratory compromise. In our case percutaneous decompression under fluoroscopy guidance resulted in a permanent cure.

OBJECTIVES: 1) To compare the Mogen and Gomco clamps with regard to pain experienced during neonatal circumcision, and 2) to assess neonatal circumcision pain with and without dorsal penile nerve block (DPNB). DESIGN/METHODS: A randomized, controlled, nonblinded clinical trial; 48 healthy, full-term infants were randomized into one of the following four groups: Gomco vs Mogen with (+) or without (-) DPNB. DPNB+ infants were injected with 0.8 mL of 1% lidocaine before circumcision. DPNB- infants received no placebo injection. Heart rate, respiratory rate, and oxygen saturation (SaO2) during the procedure were monitored and data transferred to computer files by using the Datalab software system. Crying was recorded on videotape. Pre- and postcircumcision saliva samples for cortisol analysis were collected. Heart rate, respiratory rate, SaO2, cortisol changes, and duration of crying were evaluated statistically with two-way analyses of variance and t tests. RESULTS: The type of clamp but not the use of anesthesia was significantly associated with the length of the procedure (mean Mogen time, 81 seconds; mean Gomco time, 209 seconds) and percentage of respiratory rate change. The use of anesthesia but not the type of clamp was significantly associated with percentage of crying time and percentage of SaO2 change during the procedure. Heart rate changes and total crying time were significantly associated with both the type of clamp and the use of anesthesia. Neither clamp type nor anesthesia status was significantly associated with salivary cortisol changes, although the mean increase for the DPNB- group was approximately twice that for the DPNB+ group. Fifty-six percent of infants circumcised with the Mogen clamp and DPNB did not cry at all during the procedure. CONCLUSIONS: DPNB is effective in reducing neonatal circumcision pain with either the Mogen or the Gomco clamp. For a given anesthesia condition, the Mogen clamp is associated with a less painful procedure than the Gomco. The Mogen clamp with DPNB causes the least discomfort during neonatal circumcision.

It is unknown whether the decreased cerebral blood flow seen in infants with a large patent ductus arteriosus is associated with cerebral dysfunction. Decreased cerebral blood flow in adult human and animal models has been associated with altered electroencephalography (EEG), spectral-analyzed EEG, and EEG response to photic stimulation. Cerebral blood flow velocity, EEG, spectral analysis of EEG, and photic alteration of EEG spectra were evaluated in 8 infants before and after closure of a significant patent ductus arteriosus and in 10 control infants without a patent ductus arteriosus. All infants with patent ductus arteriosus had moderate or large shunts associated with a 25% mean reduction in cerebral blood flow velocity. There were no differences, however, in EEG, spectral analysis of EEG, or photic alteration of the spectral analysis for these infants before and after patent ductus arteriosus closure as compared to controls. It is concluded that the degree of decreased cerebral blood flow in infants with a significant patent ductus arteriosus is not sufficient to cause measurable alteration in electrocortical activity.
