Mob hemolysis tshwm sim los ntawm tubing khoov thaum lub sij hawm hemodialysis yog ib qho teeb meem uas hem tus neeg mob lub neej. Txawm hais tias qhov tshwm sim ntawm hemolysis tshwm sim los ntawm tubing khoov thaum lub sij hawm hemodialysis tsawg heev, nws raug mob hnyav heev. Yog tias nws tsis pom nyob rau lub sijhawm thiab kev ntsuas tsis tau zoo, nws yuav ua rau muaj teeb meem xws li hyperkalemia, mob pancreatitis, thiab txawm tuag.
Mechanical hemolysis feem ntau yog tshwm sim los ntawm qhov sib txawv ntawm cov hlab ntsha hauv cov ntshav, suav nrog: qhov qhib ntawm rab koob yog ze rau ntawm phab ntsa ntawm cov hlab ntsha, los yog compressed los ntawm subcutaneous hematoma, uas cuam tshuam cov ntshav txaus; ib rab koob dialysis; siab dhau ntawm cov ntshav twj tso kua mis, tubing khoov, thiab ntshav yog raug shear quab yuam. Tubing khoov feem ntau tshwm sim nyob rau hauv seem ntawm sab nraum qab ntawm lub twj tso kua mis mus rau lub inlet ntawm lub dialyzer, tshwj xeeb tshaj yog nyob ze ntawm lub ruaj los yog txhawb tubing clamps thiab seem ntawm lub tubing nyob ze rau lub inlet ntawm lub dialyzer.
Kev puas tsuaj ntawm hemolysis
Hemolysis tsis tsuas yog ua rau tsis xis nyob rau cov neeg mob, tab sis kuj ua rau mob ntshav qab zib, ua rau hemodynamic instability, ua rau hemolytic vasoconstriction thiab kub siab, cuam tshuam cov ntshav txaus rau cov hlab ntsha thiab lub hlwb, los yog ua rau hypotension thiab txo cov ntshav oxygen saturation thaum dialysis. Yog tias qhov ua rau hemolysis tsis tau txheeb xyuas tam sim thiab kho kom raug, hemodialysis yuav raug yuam kom nres vim tsis muaj cov tsos mob nyem, uas yuav ua rau txo qis kev lim ntshav. Hemolysis hnyav tuaj yeem ua rau mob pancreatitis, hyperkalemia, arrhythmia, thiab txawm tuag. Qhov hnyav ntawm qhov tshwm sim ntawm hemolysis ntawm cov neeg mob yog cuam tshuam nrog tus neeg mob tus kheej yam. Lub sijhawm ciaj sia ntawm cov qe ntshav liab hauv cov neeg mob uas muaj uremia yog luv luv, oxidative kev nyuaj siab yog hnyav zuj zus, thiab muaj peev xwm antioxidant txo, tag nrho cov uas ua rau cov neeg mob muaj ntau yam hemolysis.
Kev kuaj mob ntawm hemodialysis hemolysis
Nausea, shortness of breath, abdominal/back pain, chills, and acute hypertension occur during dialysis. Severe hemolysis patients may even have their skin color turn brown. The blood color at the back of the blood line pump, especially at the venous pot, is wine-colored; after centrifuging the blood sample, the supernatant shows pink; blood tests show that serum haptoglobin is significantly reduced to disappearance, lactate dehydrogenase (LDH) is significantly increased, and hematocrit is reduced. Since the pressure alarm device cannot effectively alarm for less severe hemolysis, medical staff and technicians are mainly required to check the installation status of the pipeline, including whether the pipeline is bent, whether there is abnormal and obvious pulsation, whether the blood in the pipeline is discolored, etc., and monitor the pressure changes and trends of the pipeline. If the arterial and venous pressures are significantly reduced at the same time (>25 mmHg), lub raj xa dej tuaj yeem khoov.
