MacLoughlin R, Martin-Loeches I. Not all nebulizers are created equal: Considerations in choosing a nebulizer for aerosol delivery during mechanical ventilation. Expert Rev Respir Med 2023; 17:131-142. [PMID: 36803134 DOI: 10.1080/17476348.2023.2183194] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/22/2023]
Abstract
INTRODUCTION Aerosol therapy is commonly prescribed in the mechanically ventilated patient. Jet nebulizers (JN) and vibrating mesh nebulizers (VMN) are the most common nebulizer types, however, despite VMN's well established superior performance, JN use remains the most commonly used of the two. In this review, we describe the key differentiators between nebulizer types and how considered selection of nebulizer type may enable successful therapy and the optimization of drug/device combination products. AREAS COVERED Following a review of the published literature up to February 2023, the current state of the art in relation to JN and VMN is discussed under the headings of in vitro performance of nebulizers during mechanical ventilation, respective compatibility with formulations for inhalation, clinical trials making use of VMN during mechanical ventilation, distribution of nebulized aerosol throughout the lung, measuring the respective performance of nebulizers in the patient and non-drug delivery considerations in nebulizer choice. EXPERT OPINION Whether for standard care, or the development of drug/device combination products, the choice of nebulizer type should not be made without consideration of the unique needs of the combination of each of drug, disease and patient types, as well as target site for deposition, and healthcare professional and patient safety.

Abstract
Background Healthcare workers are committed to learning from each other's experience to safely optimize patient management of COVID-19. Acute hypoxemic failure is common in COVID-19 patients, and nearly 3.2% may require intubation. Intubation is an aerosol-generating procedure (AGP) that might predispose the performer to COVID-19 infection. This survey was intended to evaluate the practices during tracheal intubation in COVID-19 intensive care units (ICUs) and analyze them against the recommendations of the All India Difficult Airway Association (AIDAA) for safe practice. Methodology It was a web-based, multicentric cross-sectional survey. The choices in the questions were based on guidelines for airway management in COVID-19. Survey questions were divided into two parts - the first part consisted of demographics and general information, and the second part focused on safe intubation practices. Results A total of 230 responses were obtained from physicians all over India, presuming their active involvement in COVID-19 cases, of which 226 responses were taken into account. Two-thirds of responders did not receive any training before ICU posting. The Indian Council of Medical Research (ICMR) guideline was followed by 89% of responders for personal protective equipment use. Intubation in COVID-19 patients was predominantly conducted by a senior anesthesiologist/intensivist in the team and a senior resident (37.2%). Rapid sequence intubation (RSI) and modified RSI were preferable among the responder's hospitals (46.5% vs. 33.6%). In most centers, responders used direct laryngoscope for intubation (62.8%), whereas video laryngoscope was used by 34%. Most responders confirmed the endotracheal tube (ETT) position by visual inspection (66.3%) over end-tidal carbon dioxide (EtCO2) concentration tracing (53.9%). Conclusions Safe intubation practices were followed in most of the centers across India. However, teaching and training, preoxygenation methods, alternative ventilation strategies, and confirmation of intubation pertinent to COVID-19 airway management need more attention.

Critical Review of the Scientific Evidence and Recommendations in COVID-19 Management Guidelines. Open Forum Infect Dis 2021; 8:ofab376.

Abstract
BACKGROUND Little is known about the quality and potential impacts of the guidelines for coronavirus disease 2019 (COVID-19) management. METHODS We systematically searched PubMed, Web of Science, Cochrane Library, guideline databases, and specialty society websites to evaluate the quality of the retrieved guidelines using the Appraisal of Guidelines for Research and Evaluation II. RESULTS A total of 66 guidelines were identified. Only 24% were categorized as "recommended" for clinical practice. The 211 identified recommendations for COVID-19 management were classified into 4 topics: respiratory support (27), acute respiratory distress syndrome management (31), antiviral or immunomodulatory therapy (95), or other medicines (58). Only 63% and 56% of recommendations were supported by, respectively, assessment of the strength of the recommendations or level of evidence. There were notable discrepancies between the different guidelines regarding the recommendations on COVID-19 management. CONCLUSIONS The quality of the guidelines for COVID-19 management is heterogeneous, and the recommendations are rarely supported by evidence.

Pragmatic Recommendations for Tracheostomy, Discharge, and Rehabilitation Measures in Hospitalized Patients Recovering From Severe COVID-19 in Low- and Middle-Income Countries. Am J Trop Med Hyg 2021; 104:110-119. [PMID: 33534772 PMCID: PMC7957235 DOI: 10.4269/ajtmh.20-1173] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Accepted: 01/04/2021] [Indexed: 12/14/2022] Open
Abstract
New studies of COVID-19 are constantly updating best practices in clinical care. However, research mainly originates in resource-rich settings in high-income countries. Often, it is impractical to apply recommendations based on these investigations to resource-constrained settings in low- and middle-income countries (LMICs). We report on a set of pragmatic recommendations for tracheostomy, discharge, and rehabilitation measures in hospitalized patients recovering from severe COVID-19 in LMICs. We recommend that tracheostomy be performed in a negative pressure room or negative pressure operating room, if possible, and otherwise in a single room with a closed door. We recommend using the technique that is most familiar to the institution and that can be conducted most safely. We recommend using fit-tested enhanced personal protection equipment, with the fewest people required, and incorporating strategies to minimize aerosolization of the virus. For recovering patients, we suggest following local, regional, or national hospital discharge guidelines. If these are lacking, we suggest deisolation and hospital discharge using symptom-based criteria, rather than with testing. We likewise suggest taking into consideration the capability of primary caregivers to provide the necessary care to meet the psychological, physical, and neurocognitive needs of the patient.
