Volume resuscitation triangle and resuscitation success rate prediction method and system thereof

Abstract

The invention provides a volume resuscitation triangle and resuscitation success rate prediction method and system thereof. The method comprises the following steps: obtaining lactic acid, central venous pressure and fluid responsiveness in real time according to a volume resuscitation triangle theory (proposed exclusively); predicting the resuscitation success rate according to a resuscitation success rate calculation formula; and performing result interpretation according to the predicted resuscitation success rate. According to the volume resuscitation triangle and the resuscitation success rate prediction method and system thereof provided by the invention, a set of optimization scheme which is considered according to the volume resuscitation triangle can be provided for different doctors during volume resuscitation, in order to reduce unnecessary errors.

Description

technical field [0001] The invention relates to the technical field of capacity recovery, in particular to a capacity recovery triangle and a method and system for predicting success rate of recovery thereof. Background technique [0002] Severely ill patients often suffer from tissue hypoperfusion due to shock. The cause of shock may be absolute or relative insufficiency of blood volume or other reasons. It is directly manifested as an increase in blood lactic acid. The most important clinical treatment method is to restore blood volume if there is insufficient volume. Replenishing the patient with fluids to improve tissue hypoperfusion is the most direct and economical method. However, if the hypoperfusion of the tissue is not caused by insufficient volume, giving too much fluid will actually lead to the deterioration of the patient's condition, such as pulmonary edema and tissue edema, which will affect other organ functions. In this case, in order to avoid adverse conse...

Problems solved by technology

[0004] Blood lactate level as a prerequisite for fluid resuscitation: tissue hypoperfusion can lead to increased blood lactate, increased blood lactate is related to tissue perfusion, organ failure and final prognosis, but there are other factors (diffuse large B lymphoma) in blood lactate increase, so There will also be errors in judging tissue hypoperfusion simply by a rise in lactic acid

Before clinical fluid resuscitation, in addition to the blood lactate value, other indicators should be checked, such as (static indicators: central venous pressure (CVP), pulmonary capillary wedge pressure (PAWP), inferior vena cava (IVC) diameter and variability, etc.; Dynamic indicators: pulse variation rate (PPV), stroke volume variation rate (SVV), passive leg raising test (PLR), etc., two commonly used indicators are mainly considered in clinical practice: CVP and volume responsiveness, for those with positive volume responsiveness The basic principle of evaluation judges that the cardiac output of the patient is increased by more than 15%. For patients with volume responsiveness, the cardiac output can be increased by adding fluid to improve tissue perfusion; there is also CVP. However, many doctors rely on CVP to guide treatment in clinical practice, and CVP is relatively low. Even if the volume responsiveness assessment is not performed, it can be judged that the patient may have volume responsiveness, but with the increase of CVP, whether the volume responsiveness exists needs to be assessed before it can be determined. At the same time, even if there is volume responsiveness, but the CVP is at a high value, so Patients with fluid resuscitation also need to be cautious

Therefore, for fluid resuscitation considering tissue hypoperfusion for elevated lactic acid, it is necessary to determine whether to resuscitate from the LAC. In the actual process, CVP and volume responsiveness should also be considered. Comprehensive consideration can complete correct resuscitation and reduce the possibility of adverse consequences of resuscitation. At the very least, this theory is easy to understand, but the specific implementation may be different in the resuscitation methods adopted by different doctors, so there are still some adverse consequences
