Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a passive leg raising test device for predicting the fluid resuscitation responsiveness of septic shock. Background Art

[0002] Septic shock is a life-threatening acute circulatory failure and a common cause of admission in adults and children. The World Health Organization regards septic shock as a global health priority.

[0003] Fluid resuscitation is an important means for the hemodynamic resuscitation of septic shock. For adult septic shock, the Surviving Sepsis Campaign International Guidelines for the Management of Sepsis and Septic Shock recommend administering at least 30 ml / kg of crystalloid fluid within the first 3 hours of fluid resuscitation. For pediatric septic shock, the Surviving Sepsis Campaign International Guidelines for the Management of Pediatric Septic Shock and Sepsis-Associated Organ Dysfunction recommend that during initial fluid resuscitation, in units with intensive care, a bolus of 40 - 60 ml / kg of fluid should be administered within the first hour, and in units without intensive care, if the child has hypotension, a bolus of 40 ml / kg of fluid is recommended within the first hour. However, data from adults and children show that approximately 50% of adult patients and 60% of pediatric patients respond to fluid resuscitation, manifested as a 10% - 15% increase in cardiac stroke volume and / or cardiac index compared to before fluid resuscitation. Infusing fluids into patients with unchanged stroke volume after fluid resuscitation can lead to fluid overload, exacerbate pulmonary edema, induce respiratory failure, and prolong the duration of mechanical ventilation. Therefore, how to predict the responsiveness of septic shock patients to fluid resuscitation and avoid fluid overload is a very important issue faced in the rescue of septic shock.

[0004] The passive leg raising test predicts the responsiveness of fluid resuscitation in septic shock. The passive leg raising (PLR) test refers to lowering the head and trunk from a 45° angle to the supine position (lying flat), while straightening and raising the legs to a 45° angle ( Figure 1 ). The passive leg raising test is a short-term and reversible autologous blood transfusion that can cause 300 - 500 ml of blood to return from the lower limb veins to the heart, increasing cardiac preload and simulating a fluid bolus injection. The proportion of leg length to body length in children is lower than that in adults, and the effect of PLR on cardiac preload may be smaller than that in adults. Overall, the changes in cardiac output and CI caused by PLR are accurate predictors of fluid resuscitation responsiveness, supporting the use of PLR to predict the responsiveness of different patient groups to fluid resuscitation. Currently, PLR has been recommended by the 2016 Surviving Sepsis Campaign International Guidelines for the Management of Sepsis and Septic Shock for guiding fluid resuscitation in septic shock.

[0005] There are multifunctional electric ICU beds on the current market. The head of the bed can be controlled to lift up and down according to needs, and the lifting angle is 72°. The first step of PLR can be implemented by lifting the head of the bed: semi-recumbent position, with the head and torso elevated at an angle of 45°. However, the foot of the multifunctional electric bed cannot be lifted to a plane elevation of 45°, so the second step of PLR cannot be implemented, that is, the patient is in the supine position, and the legs are passively lifted, with the legs straightened and elevated at an angle of 45°. Taking the multifunctional electric ICU bed produced by Houfu Medical Equipment Co., Ltd. as an example, the head of the bed can be directly lifted at an angle of 45°, but the bed rail cannot be directly lifted, but is arched upward, and the maximum elevation angle is 20°. Therefore, how to accurately and conveniently implement PLR is a problem that needs to be solved clinically.

[0006] Therefore, in view of the deficiencies of the above technologies, the present application proposes a device for predicting the fluid resuscitation responsiveness of septic shock by passive leg raising test, which can effectively solve the above technical problems. Utility Model Content
