OBJECTIVE To compare the effects on cerebral perfusion and oxygenation of intravenous ibuprofen and indomethacin as treatment for patent ductus arteriosus in preterm infants. STUDY DESIGN Sixteen infants receiving mechanical ventilation (< 31 weeks gestation) with patent ductus arteriosus received either 0.2 mg/kg indomethacin (n = 8) or 10 mg/kg ibuprofen (n = 8) infused over 1 minute. Near-infrared spectroscopy was used to measure changes in cerebral blood volume and in oxidized cytochrome oxidase concentration. Cerebral blood flow velocity in the pericallosal artery was measured using Doppler ultrasonography. RESULTS Indomethacin caused a significant reduction of CBV (maximal changes in cerebral blood volume: -320 +/- 171 microL/100 gm) and, in four of eight patients, a fall in oxidized cytochrome oxidase concentration (maximal change in oxidized cytochrome oxidase concentration in the eight patients: -0.68 +/- 0.98 mumol/L, NS). Cerebral blood flow velocity fell significantly. Ibuprofen caused no significant reduction of cerebral blood volume, oxidized cytochrome oxidase concentration, or cerebral blood flow velocity, whereas a significant increase of cerebral blood volume (+207 +/- 200 microL/100 gm) was observed after 60 minutes. Ductus closure was seen in six of eight infants after the first dose of indomethacin and in five of eight infants after the first dose of ibuprofen. The therapeutic cycle involved administration of a second and third dose, provided no side effects occurred. Treatment was effective in all infants. CONCLUSION Compared with indomethacin, treatment with ibuprofen does not significantly reduce cerebral perfusion and oxygen availability; the observed increase in cerebral blood volume requires further investigation.

The aim of our study was to compare, using near-infrared spectroscopy (NIRS), the effects on cerebral intracellular oxygenation and cerebral blood volume (CBV) of closed endotracheal suctioning (CS), which permits continuous ventilation of the patient, with open endotracheal suctioning (OS), which requires disconnection from the ventilator. Eleven preterm infants were studied. Each patient underwent one CS, followed, after 60 min, by one OS, or vice versa, three times during the same day. Modifications in CBV and oxidized cytochrome oxidase (CytO2) were continuously detected by NIRS; arterial oxygen saturation (SaO2) heart rate (HR), transcutaneous carbon dioxide tension and mean arterial blood pressure were simultaneously recorded. Significant reductions in HR and SaO2 were observed following OS; the magnitude and duration of these negative effects of suctioning were significantly reduced with CS. In addition, the decrease in CBV was more pronounced than following CS. No changes in CytO2 concentration were seen.

Bronchopleural fistula: successful selective bronchial occlusion with a Fogarty's catheter in a preterm infant

Fabio Mosca; Maria Lattanzio; Colnaghi; S Pugliese

A preterm infant (26 weeks’gestation) mechanically ventilated for respiratory distress syndrome developed severe interstitial emphysema of the right lung with a bronchopleural fistula, pneumothorax and mediastinal shift. Selective occlusion of the right main bronchus with a Fogartys catheter produced rapid improvement in the clinical condition and radiological features. Occlusion of the main bronchus in a newborn with a bronchopleural fistula and pulmonary interstitial emphysema is an easily performed manoeuvre that can be life‐saving.Bronchopleural fistula, neonatal respiratory distress syndrome, pulmonary interstitial emphysema, selective bronchial occlusion

Comparison of The Effects of Ibuprofen and Indomethacin on PDA Closure and Cerebral Perfusion and Oxygenation. † 977

Introduction Closure of patent ductus arteriosus (PDA) with indomethacin (INDO) in preterm infants is associated with cerebral vasoconstriction leading to a reduction of cerebral perfusion and oxygenation. We have evaluated the efficacy of ibuprofen (IBU) in PDA treatment and compared, using near-infrared spectroscopy (NIRS), the effects of the two drugs on cerebral blood volume (CBV) and oxidized cytochrome oxidase concentration [cytO2].

Objectives. To compare, using cerebral near-infrared spectroscopy (NIRS), the effects of blood withdrawal (W) and infusion (I) via, respectively, UAC with tip in the thoracic aorta and UVC. Method Twelve infants of 30 weeks (25-33) gestational age, 1175 g (760-1690) birth weight, mechanically ventilated for RDS were studied at 19 hours (2-25) postnatal age. The protocol involved W, through UAC of 3 ml/kg blood in 30 seconds, followed by I at the same rate, after recovery of the NIRS trace. The procedure was repeated 3 times for UAC and 3 times for UVC. NIRS (NIRO 500, Hamamatsu Photonics), a technique based on the differential absorption of NIR light by hemoglobin and cytochrome aa3 (CytO2), depending on their oxidation state, was used to assess changes in cerebral blood volume (DCBV), calculated from total hemoglobin, oxy- (DHbO2), deoxy-(DHb) hemoglobin and CytO2, time of max variation and recovery (from start of W and I). Vital parameters, including mean arterial blood pressure (MABP) were continuously measured. Results No significant change in Hb or CytO2, heart rate, pCO2 or pO2 was seen. Concordant changes in HbO2 and CBV indicate modifications of cerebral blood flow. MABP increased significantly during I-UVC and decreased during W-UVC. A positive correlation between MABP and CBV changes during W-UVC(r2 =0.41, p = 0.036) was observed. Conclusion Blood withdrawal and infusion via UVC cause significant MABP changes and related CBV oscillation which could potentially precipitate germinal matrix hemorrhage in preterm infants; utilizing the UAC this effect may be reduced or altogether avoided.
