Problems solved by technology

[0002] CRRT (continuous renal replacement therapy) is an abbreviation for continuous renal replacement therapy, also known as CBP (continue blood purification); bedside hemofiltration is defined as a long-term, continuous extracorporeal treatment that takes place 24 hours a day or close to 24 hours Blood purification therapy is used to replace damaged kidney function. Clinically, some severe hemodialysis patients need CRRT treatment. This treatment requires a CRRT machine and its matching pipeline. The pipeline mainly includes venous pipeline (blue) , Arterial pipeline (red), and related ultrafiltration pipeline (yellow), replacement fluid pipeline (green), filter, replacement fluid, install the pipeline according to the instructions of the CRRT machine, and lead the patient's blood to the arterial pipeline Pass the filter through the venous line and then return the patient's blood to the patient's body. The routine replacement is to choose to end the treatment mode, separate the CRRT line and the arterial end of the puncture tube, receive 250ml of normal saline, return the blood, and perform maintenance on the puncture tube; Remove the pipeline and shut down the machine. Install a new pipeline after restarting the original machine for self-inspection. Pre-flush with heparin saline and soak for 20 minutes. After the normal saline washes away the heparin, connect the patient to draw blood at 50ml / min. The CRRT pipeline is connected to normal saline at the intravenous end. The blood goes to the venous pot and then connects the venous end of the tubing to the puncture port. The hemodynamic stability of continuous renal replacement therapy (CRRT) is safer than that of intermittent hemodialysis, but there is still the risk of tubing replacement. Hypotension and arrhythmia may occur due to volume changes (about 50-100ml / min) during blood flow. The occurrence of such complications will delay the recovery of the kidney and affect the prognosis of the patient. Flushing the circuit will lead to prolonged interruption of CRRT treatment for patients

Embodiment

[0021] A method for replacing a CRRT pipeline is proposed in this embodiment, comprising the following steps:

[0022] S1: Check: Check the CRRT doctor's order, patient identity information, original pipeline and parameters, and monitor the patient's vital signs;

[0023] S2: Evaluation: comprehensively evaluate the cause of the patient's blood return, the patient's hemodynamic situation, and the alarm situation during the last treatment;

[0024] S3: Material preparation: prepare alcohol cotton pads, treatment towels, NS 250ml, 20ml NS for injection, and 20ml syringe if necessary;

[0025] S4: Implementation: Check again whether the doctor's order, patient, pipeline connection and parameter setting of the new machine are correct, and the old machine returns blood;

[0026] S5: Blood introduction: start the blood pump of the new machine, the blood flow rate is 80-90ml / min, start anticoagulation, after the blood of the old machine is completely returned to the venous pot, sepa...

Abstract

The invention discloses a CRRT pipeline replacement method, comprising the following steps: S1, checking: checking CRRT doctor order, patient identity information, original pipeline and parameters, monitoring patient vital signs; S2, evaluation: comprehensive evaluation of the cause of blood return, hemodynamics of patients, and alarm during the last treatment; S3, preparation for use: alcohol cotton tablets, therapeutic towels, NS 250ml, NS for injection 20ml, syringes 20ml if necessary. The invention can reduce the interruption of CRRT, to provide a safe and effective alternative for patients with hemodynamically unstable CRRT in the process of replacing the pipeline, can guide clinical medical staff to intervene in accordance with the needs of patients in different periods of time, canstabilize the hemodynamics of patients, shorten the hospitalization time, improve the prognosis of patients, and promote the overall rehabilitation of patients.
