Application of high pressure resistant injectable PICC catheter in the treatment of patients with liver failure

【摘要】：正Objective To meet the clinical diagnosis and treatment of liver failure patients,we aim to establish a unique dual-channel venous access which can monitor central venous pressure and allow high-pressure injection of contrast agent,this method can prevent and reduce drug extravasation and manage medication safety,so that we can provide prospective nursing interventions in the emergent treatment of patients with liver failure.Methods Using Seldinger puncture technology guided by ultrasound on 26 cases of liver failure patients,we treated them
