Summary: The physicochemical properties of micronized steroid suspensions have a weak influence on droplet size distribution and aerosol deposition, but affect the conversion of the drug to inhalable aerosol. The maximum inhaled dose of budesonide is below 80-90% of the label dose, depending on the formulation. This study highlights the sensitivity of nebulization in vibrating mesh nebulizers to minor dissimilarities among generic pharmaceuticals and discusses their potential clinical relevance.

Summary: This study compared the pulmonary deposition of a jet nebulizer (JN) and a mesh nebulizer (MN) with and without a valved holding chamber (VHC) in a randomized cross-over trial. The results showed that using a VHC significantly increased pulmonary deposition for the JN, while the MN with VHC had the highest pulmonary deposition. However, the addition of a VHC did not substantially improve the efficiency of aerosol lung deposition for the JN alone.

Summary: Mechanically ventilated patients with acute respiratory distress syndrome (ARDS) often receive aerosolized iloprost, and prolonged inhalation may improve its clinical effectiveness. The use of inspiration-synchronized vibrating mesh nebulizers (VMNsyn) is a possible solution, as they achieve high drug deposition rates and longer nebulization times. In an in vitro model, the VMNsyn and a continuous vibrating mesh nebulizer (VMNcont) were compared in different ventilation modes, with the VMNsyn showing comparable deposition rates to the VMNcont during volume-controlled ventilation, but 10.9% lower during pressure-controlled continuous mandatory ventilation. The nebulization time was significantly longer with the VMNsyn during both ventilation modes. Therefore, inspiration-synchronized nebulization during volume-controlled ventilation mode seems to be the most suitable for prolonged inhalative iloprost administration in mechanically ventilated patients.

Summary: This study compared the efficacy of budesonide inhalation suspension administered via a vibrating mesh nebulizer versus a jet nebulizer in premature infants with bronchopulmonary dysplasia (BPD) undergoing high-frequency oscillatory ventilation (HFOV). The results showed that using a vibrating mesh nebulizer for budesonide inhalation suspension resulted in improved oxygenation index and reduced arterial partial pressure of carbon dioxide compared to a jet nebulizer, indicating superior therapeutic efficacy.

Summary: This study evaluated the performance of a therapeutic vibrating mesh-type nebulizer for the pulmonary delivery of radioaerosols for lung scintigraphy in healthy subjects. The results showed that the delivery efficiency and penetration of aerosols to the peripheral lung were similar to commercialized jet-type nebulizers.

Summary: Aerosol delivery is important in emergency department treatment of patients with respiratory distress, with newer devices like vibrating mesh nebulizers showing potential for improved outcomes. Further controlled studies are needed to evaluate the impact of these devices on patient outcomes and dosing strategies. Future efforts should focus on applying new evidence to update guidelines and treatment strategies.

Summary: The introduction of external gas in the NIV circuit can lead to asynchronies in both bench and patient studies, with autotriggering being the most common issue. Variations were observed based on the ventilator model and gas source used. Monitoring the patient at the initiation of treatment is recommended due to the variable impact of external gas on ventilator triggers.

Summary: The study found that filtering the exhalation port of a manual resuscitation bag can effectively reduce the levels of medical aerosols released into the environment during aerosol drug delivery. Additionally, there is significant variation in the amount of aerosol delivered to the simulated patient lung depending on the type of nebulizer used.

Summary: This review discusses the use of aerosol therapy in mechanically ventilated patients, with a focus on jet nebulizers (JN) and vibrating mesh nebulizers (VMN). Despite VMN's superior performance, JN remains the more commonly used type. The selection of nebulizer type should consider the unique needs of the drug, disease, and patient, as well as safety considerations.

Summary: Recent research indicates that children who unintentionally ingest cannabis often undergo extensive additional testing, such as head imaging or lumbar puncture. However, the yield of these tests is limited. While head imaging and lumbar puncture are frequently performed, diagnoses such as skull fracture, intracranial hemorrhage, intracranial neoplasm, meningitis, or intracranial abscess are rare. Additionally, discharge diagnoses related to other drugs are infrequent. The most common co-diagnoses are cocaine and opioids. Therefore, prompt consideration of cannabis ingestion and quick identification through testing may result in more effective neuroimaging outcomes.
