What are the symptoms of excessive blood loss?

If excessive blood loss occurs for some reason, it will cause great harm to the patient's health. Excessive blood loss often leads to hemorrhagic shock. Before the shock, the patient will appear pale, have a cold body, and have a weak pulse, etc. If no further good treatment is paid attention to, the patient will gradually fall into a coma, and even cause an extreme drop in blood pressure, which may lead to death.

What are the symptoms of excessive blood loss?

1. Heavy bleeding. The most common symptom of hemorrhagic shock is heavy blood loss. If someone around you is bleeding heavily, you must be alert to whether the patient will develop hemorrhagic shock.

2. Patients with hemorrhagic shock are prone to mental tension, irritability, pale complexion, cold hands and feet, accelerated heart rate, fluctuating blood pressure, and weak pulse before shock.

3. In addition to the above symptoms, patients with hemorrhagic shock will further develop apathy, slow reaction, and sometimes even unconsciousness or coma.

4. When sent to the hospital for examination, it was found that patients with hemorrhagic shock had low blood pressure, weak pulse pressure, cold limbs, unclear pulse, and unmeasurable blood pressure.

What to do if you lose too much blood

1. Excessive blood loss and shock require close observation to prevent blood loss

Heavy blood loss due to an accident. For patients in shock, it is important to note that when they are carried to the treatment site on a stretcher, the patient's head should be close to the stretcher bearers behind them. This will make it easier to closely monitor the patient in shock at all times to respond to worsening of the condition. When transporting the patient to the hospital, the patient's head should be pointed in the opposite direction of the vehicle (ambulance, airplane, etc.) to prevent further blood loss in the patient's brain due to acceleration.

2. Shock caused by excessive blood loss requires large amounts of rapid fluid replacement

As the infusion channel is established, give a large amount of rapid fluid infusion immediately. For severe shock, 1 to 2 L of isotonic balanced salt solution should be rapidly transfused, preferably followed by cross-matched blood. To save lives, concentrated red blood cells of the same type or type O can be transfused. Especially after the application of balanced salt solution, when the blood volume cannot meet the requirements of resuscitation during recovery, concentrated red blood cells should be transfused to make the hemoglobin reach above 10g/dl. However, in cases where bleeding does not stop, it is inappropriate to use the above method of fluid resuscitation and blood transfusion, because vigorous fluid resuscitation will flush out blood clots in the blood vessels, increase blood loss, and reduce survival rate.

3. Treatment of shock due to excessive blood loss

In the treatment of hemorrhagic shock, the first procedure is to ensure that the airway is open and that hemostasis is effective. Airway patency is the basic condition for ventilation and oxygenation and should be ensured. Patients with severe shock and circulatory failure should also be intubated and given mechanical ventilation. Stopping bleeding is an important measure to prevent the occurrence and development of shock. Compression hemostasis is a feasible and effective emergency measure; the use of tourniquets is also very effective. Two intravenous lines should be established as soon as possible.
