Hemorrhagic shock symptoms?

summary

There is no doubt that hemorrhagic shock is a matter that needs to race against the clock. The shock caused by a large amount of blood loss due to trauma is called hemorrhagic shock. Hemorrhagic shock is a very dangerous disease, if not treated in time, then the result will be serious. Therefore, it is necessary to know more about this aspect. What are the symptoms of hemorrhagic shock? Now let's talk about it.

Hemorrhagic shock symptoms?

First: in many cases, the diagnosis of bleeding is not too difficult. History and physical signs can reflect the insufficiency of intravascular volume and the compensatory reaction of adrenal energy. However, the experimental detection is not completely so. Because in a short period of time after acute blood loss, the movement of body fluid can not be very obvious, it is difficult to reflect through the blood test indicators. If the process of blood loss is a little longer and the movement of body fluid increases gradually, the blood will be concentrated, which is manifested by the increase of hemoglobin, hematocrit and the ratio of urea nitrogen to creatinine. If the process of blood loss is long and the amount of blood loss is large, especially the loss of free water gradually increases, the serum sodium will increase. In a word, the amount of blood loss in shock should be fully estimated, but it is often underestimated in clinic.

Second: when the blood loss is large, causing severe hypovolemic shock, and it is difficult to grasp the practical and regular changes in clinical practice, especially the resuscitation and rehydration therapy is difficult to show positive results, it should be considered that the central venous catheter or pulmonary artery catheter can be placed for invasive hemodynamic monitoring. Central venous pressure (CVP) and pulmonary artery wedge pressure (PCWP) decreased, cardiac output blood loss decreased, venous oxygen saturation (SvO2) decreased, and systemic vascular resistance increased.

Third: for people in shock, the head can be slightly lowered. But don't put it too low. For patients with dyspnea, pulmonary edema or head injury, the head should be slightly raised. The main symptoms are decreased blood pressure, pale complexion and cold limbs.

matters needing attention

For such a common sudden disease, a little more understanding means that you are likely to better deal with such a situation. Hemorrhagic shock is dangerous and we should pay more attention to it.
