Long-Term Results of a Standard Algorithm for Intravenous Port Implantation

Three-Dimensional Simulation Training for Oncology Nurses to Address Pitfalls in Current Irrigation Strategy for Intravenous Ports: Repeated Measurements Study

OBJECTIVE

We designed an interactive visual training course and three-dimensional (3-D) simulator for participants and used verified questionnaires as tool to evaluate the efficacy of the education course.

DATA SOURCES

From August 2020 to December 2021, 159 nursing staff who received the interactive visual training course and completed validated questionnaires before and after the course were included. The efficacy of the course was evaluated by comparing the pre- and post-course questionnaires.

CONCLUSION

The interactive visual training course, including maintenance lectures and practice with a 3-D simulator, improved consensus among the nursing staff and increased the willingness of oncology nurses to perform the proposed port irrigation procedure.

IMPLICATIONS FOR NURSING PRACTICE

An implanted intravenous port cannot be directly seen by nursing staff and can only be identified through manual palpation. This lack of visibility may result in individual variations in port identification during daily practice, potentially leading to malpractice. To minimize these individual variations, we have designed an interactive visual training course. We used validated questionnaires before and after the course to analyze its efficacy in practical education.

Cephalic Vein Cut Down for Total Implantable Venous Access Ports: A Retrospective Review of a Single Institution Series

Objective

The aim of this work was to describe the early and late success rates of cephalic vein cut down (CVC) in the implantation of totally implantable venous access ports (TIVAP) for chemotherapy treatment in oncological patients.

Methods

This was a retrospective study of 1 047 TIVAP performed in a private institution between 2008 and 2021. The CVC with pre-operative ultrasound (PUS) was the initial approach. All cephalic veins (CVs) were mapped pre-operatively with Doppler ultrasound, measuring their diameter and course in oncological patients who required a TIVAP. With a CV diameter ≥ 3.2 mm TIVAP was carried out by CVC; with CV diameter < 3.2 mm, subclavian vein puncture (SVP) was performed.

Results

1 047 TIVAPs were implanted in 998 patients. The mean age was 61.5 ± 11.5 years, 624 were women (65.5%). Male patients were significantly older and with a higher incidence of colonic, digestive system, and laryngeal cancer. Initially, TIVAP was indicated in 858 cases (82%) by CVC and 189 (18%) by SVP. The success rate was 98.5% for CVC and 98.4% for SVP. There were no complications for CVC (0%) but five early complications (2.5%) in the SVP group. The rates of late complications were 4.4% in the CVC group and 5.0% in the SVP group, foreign body infection being the most frequent (57.5% of the cases) (p = .85).

Conclusion

The CVC or SVP using PUS for TIVAP deployment, performed through a single incision, is a safe and effective technique. This open but minimally invasive technique should be considered in oncological patients.

Outcomes of Port A Catheter Implantations in Cancer Patients: Experience in 102 Cases

Aim

This study evaluates cancer patients undergoing port catheter implantation.

Patients and methods

The study was conducted among patients admitted to the cardiovascular department of Düzce State Hospital from June 2018 to July 2020. The inclusion criterion was the implantation of a vascular port for at during 2 years. One hundred and two patients were enrolled in the study. The most common acute outcomes such as pneumothorax, haemothorax, thoracic duct damage and cardiac tamponade and the demographic characteristics of all patients were recorded. Patients were evaluated for the late complications of port catheter, such as thrombosis, infection and kinking, catheter fracture and occlusion.

Results

Complications of port catheter occurred early (≤30 days) and delayed (>30 days) at rates of up to 8% and 15%, respectively. The most common early and late complications were pneumothorax and non-functional port (occlusion, thrombosis, kinking), respectively.

Conclusions

Thrombosis is the most common cause of dysfunction in central port catheters used in the treatment of cancer patients. Routine radiological imaging can help in early detection of catheter-related complications.

A novel homemade simulator for training and assessing competency of totally implantable venous access port implantation via venous cutdown

Total implantable venous access port (TIVAP) by cephalic vein cutdown (CVCD) is one of the first procedures surgery residents can be performed independently under supervision. There is currently a lack of affordable simulators for teaching and assessing TIVAP competency to improve patient safety. A panel of 10 experts divided the TIVAP by CVCD procedure into 9 steps. A homemade, low-cost ($3 USD) simulator was then designed for practicing standardized procedural steps in the context of a simulation-based mastery learning course. Residents were given a simulator for at-home practice and completed a survey evaluating the simulator and their learning experience. Twenty-eight first-year surgery residents participated in the course and completed the survey. They were highly satisfied with the simulator (mean score = 8.7 of 10) and generally agreed with its anatomical appearance and functional fidelity. They also appreciated the educational value of using this simulator to learn and practice basic techniques and procedural steps. Our novel, homemade simulator of CVCD TIVAP implantation is a cost-effective way of achieving procedural competence of a basic operation for inexperienced surgery residents. We envision the same principle can be applied to other procedures to enhance resident education.
