A prospective Comparison of Porta-Sonic and Fisoneb Ultrasonic Nebulizers for Administering Aerosol Pentamidine

We conducted a prospective, unblinded, nonrandomized, multiple crossover study to assess the acute pulmonary effects of a new jet nebulizer-Parineb, comparing it to Respirgard II (jet nebulizer) and Fisoneb (ultrasonic nebulizer) for administering aerosol pentamidine (AP). Twenty-three HIV patients received AP at 60 mg dissolved in 3 ml sterile water with Parineb and Fisoneb and 300 mg dissolved in 5 ml sterile water with Respirgard II on three successive clinic visits. Twelve patients known to develop bronchospasm with AP received 200 micrograms of salbutamol as premedication for all three nebulizers. Eleven subjects received AP without bronchodilator premedication. All subjects had a reduction in flow rates with AP. No significant difference was noted in the reduction of flow rates between the three nebulizers in those patients without prior history of bronchospasm with AP. However, there was a significantly greater reduction in flow rates with Parineb in patients with known AP-induced bronchospasm despite premedication with bronchodilator. This decrease in flow rates with Parineb was not felt by patients based on the subjective rating of cough using a visual analog score when compared to the other two nebulizers. Parineb should be used cautiously in individuals with known AP-induced bronchospasm.

A prospective Comparison of Porta-Sonic and Fisoneb Ultrasonic Nebulizers for Administering Aerosol Pentamidine

Abstract: This study suggests that Porta-sonic, the newer nebulizer system, with more ideal in vitro characteristics may become a favoured device in clinical practice.
