Why can have discharge of sexual discharge of nose of mouth blood?

summary

Oral and nasal bloody secretions are common in patients who drown for more than 5 minutes. Drowning is defined as wet drowning when a person is submerged in water and his respiratory tract is blocked by foreign bodies such as water or mud grass (the mortality rate is 70% - 80%), or dry drowning is defined as dry drowning when the respiratory tract is blocked by reflex spasmodic obstruction of epiglottis, larynx and trachea in a short time after drowning (the mortality rate is 10% - 20%). Those who are endangered but not dead are called on the verge of drowning, and those who are dead are called drowning.

Why can have discharge of sexual discharge of nose of mouth blood?

Drowning can be caused by people who do not have the ability to save themselves from drowning, or by people who are not familiar with the current and topography of rivers and ponds, or by people who commit suicide or accident. In the early stage of drowning, there were reflexive breath holding, laryngeal bronchospasm and mud grass blocking the mouth and nose, which aggravated the asphyxia. Therefore, about 20% of the drowned people did not inhale water into the lungs or only a small amount of water reached the throat, which resulted in respiratory tract occlusive laryngospasm lasting for 3 to 5 minutes. Later, laryngeal loose caused water to enter the respiratory tract and alveoli, and the surfactant of alveoli was damaged, resulting in insufficient function, Leading to dysfunction of ventilation and ventilation *, hypoxia and carbon dioxide retention, and hypoxia in all organs.

In order to save the drowning patients, we should immediately remove the mud and grass in the mouth and nose, pull out the tongue to make the respiratory tract unobstructed, if necessary, perform fiberoptic bronchoscopy to remove foreign bodies in the airway, prone the patient on the knee for drainage, so as to fight for the rescue time, and inject atropine into the patients with respiratory arrest to inhibit the vagus reflex and make the lung expand, The former is better than the latter. Positive pressure can expand alveoli, improve ventilation and ventilation. Intravenous drip of nicothamide and doxapram can be used to monitor blood gas analysis and adjust ventilation volume and oxygen concentration.

Laboratory examination: the drowning people often have a slight increase in white blood cells, blood potassium, blood and urine free hemoglobin. About 75% of the patients had mixed acidosis. With local X-ray or CT examination or nasal endoscopy, combined with clinical symptoms to determine [laboratory examination]: drowning often has [[white blood cells]] slightly increased, blood potassium increased, blood and urine free [[hemoglobin]][[ About 75% of the patients had obvious mixed type [[acidosis]]== The treatment and prevention methods of oral and nasal secretions = = strengthen the publicity of swimming safety knowledge, do [[preparatory activities]] before swimming to avoid [[gastrocnemius spasm]], and go into the water together.

matters needing attention

We should pay attention to the length of drowning time, especially the head and intracranial injury. In case of drowning, divers and deep-water swimmers should carefully identify whether there are improper decompression and other factors before drowning, because the two methods of treatment are completely different. Strengthen the publicity of swimming safety knowledge, do preparatory activities before swimming, avoid gastrocnemius spasm, and go into the water together. Strengthen the education of safety and first aid knowledge for offshore operators.
