Symptoms of dry drowning?

summary

Dry drowning refers to the phenomenon of drowning after landing. That is to say, there is no drowning in the process of swimming, but at this time, the water enters the lungs, leading to pulmonary edema. At this time, the patient may not be able to breathe, causing death. There is a certain concealment, and there is a certain incubation period.

Symptoms of dry drowning?

Dry drowning refers to laryngospasm, airway obstruction, resulting in asphyxia. When laryngospasm occurs, it can cause cardiac reflex arrest, or cardiac arrest due to asphyxia and myocardial hypoxia.

There is no or little water in the lungs of these patients. Most of the Drowners belong to dry drowning or a small amount of lung water. When dry drowning occurs, the first symptoms are dry lips, dyspnea, facial swelling, drowsiness, burnout, and then coma, asphyxia and even drowning. From the pathogenesis point of view, it can mainly cause brain edema, reflex malignant arrhythmia and cardiac arrest after asphyxia.

However, a small number of patients, after being rescued ashore, inhaled only a small amount of water in their lungs. On the surface, there was no obvious abnormality in their early state of consciousness, respiration, oxygenation and circulation, but they developed severe respiratory distress or even life-threatening after a few hours or even 72 hours, which is called "secondary drowning", which is essentially a continuous pathological change process after drowning. At present, the mechanism is not clear, which may be related to the destruction of pulmonary surfactant by water entering the lung.
