Analysis on Related Factors and Nursing Interventions of Vasovagal Syncope During Ultrasound-guided PICC

Purpose: To investigate the causes and the nursing interventions of vasovagal syncope (VVS) during ultrasound-guided Modified Seldinger Technique (MST) PICC catheterization. Methods: Clinical data (medical records, demographic data, diagnosis, local vascular compression situation, B-mode ultrasound-recorded catheter/vessel ratio and the occurrence time, symptoms and treatment of syncope) of 14 patients diagnosed as vasovagal syncope during ultrasound-guided PICC catheterization at three hospitals in Guangdong province from September 2018 to September 2019 were collected for this retrospective analysis. Results: There were 3091 cases of ultrasound-guided MST PICC catheterization in the venous catheter outpatient clinics of the 3 hospitals from September 2018 to October 2019 with 14 cases (0.45%) of intraoperative vasovagal syncope, all cancer patients (5 males, 9 females) with a mean age 45± 3.8. They all received PICC for the first time and were under mental stress during the operation. Among the 14 patients (2 mild, 7 moderate, 5 severe), 8 had multiple lymphadenectasis in the neck and clavicular areas of the catheterization side, which resulted in different degree of venous compression and difficulty in insertion; 5 had catheter/vessel ratio over 45%. 2 cases of VVS occurred when the patients were asked to turn their heads against shoulders on to the puncture side; 10 occurred when using B-mode ultrasound probe to examine the jugular vein; 2 occurred when pulling out the catheter sheath. Conclusion: The related factors of vasovagal syncope during ultrasound-guided PICC catheterization include overcompression and avulsion on blood vessels and mental stress. Therefore, it is recommended to implement psychological interventions before surgery, reduce compression and avulsion of the vascular access during catheterization, and improve practitioners’ abilities in vessel selection (vessels with a catheter/vessel ratio less than 45%) and catheterization skills to eliminate the incidence of vasovagal syncope during PICC catheterization.

Venous access in cancer patients.

The most commonly used permanent venous access devices in cancer patients are the port, PICC port and PICC catheter (peripherally inserted central catheter). It is always necessary to consider the type of venous access needed for each individual cancer patient. Implantation should be performed using modern instruments to minimize the risk of early and late complications and thereby adelay in oncological treatment. The use of ultrasound is recommended at all stages of introduction. Precise tip placement of the central catheter in the sinoatrial junction region further reduces the number of thromboses arising in the catheter. Atrend towards the treatment of catheter infections is certainly to maintain the venous access without compromising the patientshealth. Permanent venous access devices allow the application of chemotherapy and repeated blood sample collections with minimal impact on the quality of life in cancer patients.

P1.07-13 The Application of Intracavitary Electrocardiogram in the Femoral Vein Catheter Tip Location in Chemotherapy Patients with Lung Cancer

For lung cancer patients with superior vena cava obstruction (SVCO), femoral vein PICC catheter at mid-thigh can be used to achieve chemotherapy. The X-ray, as the gold standard for catheter location, has some limitations such as long time-consuming and delayed in judgment. The intracavitary ECG location has been applied to the superior vena cava (SVC) catheter, which can make up for the shortcomings of X-ray. However, it is not clear whether it is suitable for inferior vena cava (IVC) catheter. Our research aim is to explore the clinical application value of intracavitary ECG location on femoral vein PICC at the mid-thigh. From January 2017 to December 2018, a total of 91 patients with SVCO, who were placed femoral vein PICC at the mid-thigh, were in enrolled. In the self-controlled study, catheter tip at the eighth to tenth thoracic vertebrae by X-ray location as the gold standard positive, and catheter tip at the position where the intracavity ECG occurred the first biphasic P wave and then receding 2 cm as the positive for the screening test. The study calculated the authenticity, reliability and practicality indicators of intracavitary ECG location. This study found the relationship between the position of the catheter tip and the P wave. When the tip of the catheter was in the IVC, most patients has negative P wave, and some patients has a low flat positive P wave. When the tip of the catheter entered the right atrium (RA), patients has biphasic P wave, and when the tip of the catheter entered the top of the RA, patients has huge biphasic P wave. In the study, the screening test was used to evaluate the accuracy and clinical application potential of intracavitary ECG in femoral vein PICC catheter tip location. In the authenticity index, the sensitivity was 98.73%, and the specificity was 91.67%. Yoden index was 0.90, the accuracy was 97.80%, the false positive rate was 8.33%, the false negative rate was 1.27%, the positive likelihood ratio was 11.85, and the negative likelihood ratio was 0.01. In the reliability index, the Kappa index value was 0.90. In the practical index, the positive predictive value was 98.73%, and the negative predictive value was 91.67%. Intracavitary ECG location can accurately locate the tip of the femoral vein PICC catheter at the mid-thigh. It has higher reliability and practicability, and has more great clinical application potential. It is worthy to clinical application.

The Effects of Simulated Teaching on Prevention of Catheter Extrusion of Patients with PICC

Objective: To explore the effects of simulated teaching on avoidance of catheter extrusion in patients with PICC. Background Catheter extrusion is one of the most common complications after PICC catheterization. The incidence is 5% to 3l% in literature which have reported. Catheter prolapse not only directly affects the treatment of patients, but also increases the pain and financial burden of patients. The main causes of catheter prolapse are improper external fixation, traction of external force, excessive activity of patients and lack of self-protection catheter knowledge. Health education can promote patients who are the co-administrator of the catheter to form correct behaviors and concepts. Health education has become an important part of clinical nursing work. Methods: A total of 915 patients with PICC were recruited in the present study. Simulated teaching regarding prevention of catheter extrusion to get her with previous health education was carried out in the laboratory center. Participants were required to do re-demonstration after the critical skills were taught. The tests core was compared before and after the simulated teaching . Besides , the rate of catheter extrusion was also recorded and compared with those patient s who did not receive the simulated teaching before. Results: Compared with the test score before the simulated teaching, test score after the teaching was higher. Rate of catheter extrusion among those who received simulated teaching was lower than those who did not get the teaching (χ2= 23.701, P< 0.001). Conclusion: Health education with simulated teaching can help patients with PICC know the key points that they should pay attention to. Such teaching method can significantly decrease the rate of catheter extrusion.
