Embodiment 1

[0034] A method for replacing a CRRT pipeline, comprising the steps of:

[0035] Step1: Confirm the patient's identity information, check the patient's case, summarize the reasons for blood return, observe his mental state, ask simple questions about his own condition, and use professional equipment to detect;

[0036] Step2: Disinfect the deep vein cannula according to the aseptic operation procedures, prepare a 5ml syringe to indwell with 2ml glycine water, a 20ml empty syringe and a V tube;

[0037] Step3: Perform pipeline preflushing, adjust the position of the patient and the position and direction of the catheter;

[0038] Step4: Connect one end of the hemofiltration line to the corresponding end of the patient's deep vein catheter, turn on the blood pump, the blood flow rate is not higher than 100ml / min, start anticoagulation, and take a sample at the sampling port when the blood is drained to the filter , the blood is diverted to one end of the V tube, the pressure se...

Embodiment 2

[0056]For the specific operation principle of the method of the present invention, the percutaneous puncture catheter is used in Step4, and the femoral vein is selected for venous catheterization, so as to ensure the effect of compression and hemostasis, reduce the incidence of hematoma, and at the same time, it is more convenient to puncture, and the technical requirements are lower. In the protocol, Step 11 is used to seal the tube first with normal saline and then with heparin solution. The tip of the catheter is wrapped with a sterile therapeutic towel. In the protocol, Step 4 can be used to prevent blood coagulation. Filter, to prolong the service life of the filter, after dilution, the replacement fluid is mixed with the blood purified by the filter and then returned to the body, and the blood collection and administration at the sampling port are reduced, the blood pump is not easily turned off, and the monitoring is strengthened at the same time.

Abstract

The invention discloses a CRRT pipeline replacement method. The CRRT pipeline replacement method comprises the following steps: Step 1, confirming identity information of a patient, checking a case ofthe patient, summarizing blood return reasons, observing the mental state of the patient, inquiring a problem about a simple self condition of the patient, and performing detecting by using a professional instrument; Step 2, disinfecting a deep vein cannula according to sterile operation instructions, and preparing a 5ml injector to retain 2ml of glycyl water, a 20ml empty injector and a V tube;Step 3, performing pipeline pre-flushing, and adjusting the body position of the patient and the position direction of a catheter; and step 4, connecting one end of a blood filtering pipeline with thecorresponding end of a deep vein indwelling catheter of the patient, starting a blood pump, controlling the blood flow speed to be not higher than 100ml / min, starting anticoagulation, performing sampling at a sampling port when blood is sparsely guided to a filter, sparsely guiding the blood to one end of the V tube, sensing a signal by a pressure sensor, closing the blood pump and connecting oneend of the V tube of the deep vein indwelling catheter. The CRRT pipeline replacement method is easy and convenient to operate, the treatment progress of the patient can be kept, no extra adverse effect is caused to the physical condition of the patient, and use is safe.

Description

technical field [0001] The invention relates to the technical field of CRRT pipeline replacement, in particular to a CRRT pipeline replacement method. Background technique [0002] CRRT continuous renal replacement therapy is defined as a blood purification treatment technique that continuously and slowly removes water and solutes through extracorporeal circulation blood purification to replace kidney function. Compared with ordinary hemodialysis, CRRT prolongs the treatment time of blood purification and reduces It improves the treatment efficiency per unit time, minimizes the impact of solute concentration and volume changes in the blood on the body, and uses high-permeability and biocompatibility filters to provide extremely important internal stability for the treatment of critically ill patients. There are three main methods of solute removal in CRRT: diffusion, convection, and adsorption. Different treatment modes have different removal mechanisms. Hemodialysis is main...
