Nose and nose bloody discharge
Introduction
Introduction Oral and nasal blood secretions are common in patients with a drowning time of more than 5 minutes. People are submerged in water, the respiratory tract is blocked by foreign matter such as water or mud, called wet sputum (sickness rate 70% to 80%), or the epiglottis, throat, trachea, reflexive phlegm, and respiratory tract are called dryness. (CFR 10% to 20%), whether wet or dry, can cause asphyxia, ventilatory disorders, severe hypoxia, respiratory failure, and even breathing, heartbeat. Those who are endangered but not dead are said to be drowning, and the dead are called drowning.
Cause
Cause
Waterborne people who are incapable of self-rescue, or river ponds that are unfamiliar with water flow and terrain, are mistakenly entering the danger zone, and suicide or accidents can be drowned. At the beginning of the drowning, reflexive breath holding, laryngeal bronchospasm, and muddy clogging of the nose and mouth make the asphyxia worse. Therefore, about 20% of the drowning people do not have water inhaled into the lungs or only a small amount of water to the throat, which lasts for 3 to 5 minutes. Respiratory occlusive sore throat, followed by delayed release of sore throat into the respiratory tract and alveoli, impaired alveolar surfactant and insufficient function, leading to pulmonary ventilation and ventilation dysfunction, resulting in hypoxia and carbon dioxide retention, hypoxia in various organs disfunction.

Laboratory tests for fungal infections
Diagnosis: According to the medical history, the drowning diagnosis was established.
Laboratory tests: Drowning patients often have mildly elevated white blood cells, elevated blood potassium, and free hemoglobin in blood and urine. The pH was determined in about 75% of cases with obvious mixed acidosis.
Diagnosis
Differential diagnosis
Other ancillary examinations: chest X-rays showed patchy infiltration, sometimes with signs of typical pulmonary edema.
Pay attention to the length of drowning time, paying special attention to the presence of head and intracranial injuries. When drowning and deep-water swimmers are drowning, they should carefully identify whether there are any factors such as improper decompression before drowning, because the treatment methods are completely different.
