Hemorrhagic shock
Overview: Excessive blood loss over the body compensatory function, can not provide adequate tissue perfusion and oxygen supply, hemorrhagic shock occurs, mainly in trauma, but can also occur in spontaneous bleeding (such as gastrointestinal bleeding and childbirth). Common clinical is acute onset of hemorrhagic shock.
Clinical manifestations:
1. dizzy, pale, a cold sweat, cold ache.
2. irritability or calm expression, severe syncope, and even coma.
3. Fine pulse, blood pressure, shortness of breath.
Less urine or even no urine.
Diagnostic requirements:
Acute secondary to a large number of blood loss history.
2. Have thirst, excitement, irritability, and then appear indifferent, vague mind, and even coma.
3. Superficial vein collapse, pale complexion, shallow breathing soon.
4. Fine pulse, skin wet, body temperature drops.
5. Systolic blood pressure less than 90mmhg, or hypertension, blood pressure decreased by 20%, capillary filling time, decreased urine output (less than 30ml urine output per hour).
6. Central venous pressure and pulmonary artery pressure measurement helps to monitor the degree of shock.
Treatment programs and principles:
1. Immediate Vital Signs Monitoring ECG, blood pressure, respiration, pulse and urine output.
2. Blood and blood type, blood biochemical and electrolyte, blood gas analysis.
3. Quickly add blood volume.
4. On the basis of expansion of the use of vascular drugs to maintain tissue perfusion.
5. Etiological treatment quickly identify the cause, to stop bleeding, including surgical treatment.
Disposal:
1. Correct shock while rapidly diagnosing and treating potential bleeding.
2. Blood pressure ECG monitoring, should establish more than two large-caliber venous access.
3. Fluid recovery, transfusion if necessary treatment.
4. To complete the initial rehydration, preparation of wood and other basic treatment, patients with hemorrhagic shock should be transferred to the operating room or I CU close supervision
Measured, carefully treated.
Intention 1 Patients with severe hemorrhagic shock may have coagulation disorders, M B and other complications. Hemorrhagic shock occurred
Maternity, to ensure that the mother's tissue perfusion is the key to ensuring fetal blood supply.
