PEP-device for Treatment of Swimming-induced Pulmonary Edema (SIPE)

Status Recruiting

Clinical Trial Summary

In swimming induced pulmonary edema (SIPE), there is a lack of knowledge regarding optimal treatment. The present study was designed to assess the benefit of treatment with positive expiratory pressure device (PEP-device) compared to spontaneous recovery in patients with SIPE without hypoxia in the out-of-hospital environment.

Clinical Trial Description

Swimming induced pulmonary edema (SIPE) is an unusual condition affecting otherwise healthy swimmers. SIPE is characterized by acute onset of dyspnea and cough, excessive sputum and occasionally hemoptysis when swimming in open water. The condition usually resolves spontaneously within 48 hours, but may result in serious illness and require emergency care. Case reports describe acute treatment with or without oxygen in combination with diuretics, beta-agonist-inhalation or continuous positive airway pressure (CPAP). Evidence for optimal treatment strategy is lacking. Oxygen treatment might not be appropriate for patients with SIPE presenting without hypoxia. It is unknown if positive airway pressure accelerates recovery in SIPE. This study intends to determine whether treatment with positive expiratory pressure (PEP) applied by PEP-device accelerates increase of oxygen saturation compared to spontaneous recovery in patients presenting with SIPE without hypoxia. The aim is to treat patients on site without involving hospital care. We study a large cohort of approximately 12 000 swimmers during Vansbrosimningen, Sweden's biggest annual open water event with a yearly incidence of SIPE about 0,4%. Adult patients clinically diagnosed with SIPE and oxygen saturation ≥92% are randomly assigned to 2 groups: (1) PEP-device for 20 minutes or (2) control group with spontaneous recovery without active treatment for 20 minutes. Assessment with outcome measures is taken 10 minutes after intervention/control. Primary endpoint: oxygen saturation (%) by pulse oxymetry. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
