Abstract:  When using ventilators in the management of the coronavirus disease 2019 patient, dense and abundant mucous secretions are formed, obstructing the endotracheal tube and making its aspiration difficult. This situation is worsened if in order to minimize the risk of infection of the medical personnel, the humidifier is disconnected. This circumstance forces the tube to be removed, cleaned, or changed, increasing the workload of the intensive care unit staff. Other therapies tested until now, like mesna, acetylcysteine, or hypertonic saline solution, are valid alternatives, although they have not shown great efficacy for this specific procedure in the past. The sanitary emergency forced the collaboration between a pharmacist and an otorhinolaryngologist to develop the cocamidopropyl betaine surfactant formula, after several tests with different concentrations of the surfactant. The objective of this compounding formula was to resolve a mechanical problem and avoid reintubation due to obstruction of the ventilator tube. The cocamidopropyl betaine surfactant solution 0.075% in saline 0.9% (physiological serum) solution demonstrated to be a well-tolerated formula, using inexpensive materials, was simple to prepare, and was easy to use in clinical practice.
