[Venous access in oncology]

Area of Science:

• Oncology
• Vascular Access
• Infectious Disease

Background:

• Cancer treatments often necessitate venous access via peripheral or central veins.
• Central venous catheterization is an invasive procedure requiring strict aseptic techniques and protocols.
• Complications associated with central venous access include infection, thrombus formation, and mechanical issues.

Purpose of the Study:

• To highlight the risks associated with central venous catheter use in cancer patients.
• To emphasize the importance of adhering to strict protocols during catheter insertion and maintenance.
• To underscore the benefits of central venous access despite potential complications.

Main Methods:

• Review of common complications associated with central venous catheters.
• Discussion of infectious complications, including causative agents and management.
• Analysis of thrombotic complications and their treatment options.
• Examination of mechanical complications such as displacement and obstruction.
• Emphasis on preventative measures and maintenance protocols.

Main Results:

• Infectious complications range from 18-25% of nosocomial infections, often linked to Gram-positive bacteria.
• Thrombus formation occurs in 4-42% of cases, presenting diagnostic and management challenges.
• Mechanical complications like displacement, rupture, obstruction, and extravasation are frequent.
• Standard heparinization and rinsing protocols are crucial for maintaining catheter patency.

Conclusions:

• Central venous access is indispensable for modern cancer therapy.
• Vigilant monitoring and adherence to aseptic protocols are critical to mitigate risks.
• Despite potential complications, the benefits of central venous access in cancer care are undeniable.
