Summary
Peripherally inserted central catheters (PICCs) increase deep vein thrombosis (DVT) risk, especially in cancer patients and with larger gauges. Careful consideration of PICC size and patient history is crucial for prevention.
Area of Science:
- Vascular access devices
- Thrombosis research
- Medical device safety
Background:
- Peripherally inserted central catheters (PICCs) are widely used but linked to deep vein thrombosis (DVT).
- Identifying factors contributing to PICC-associated DVT is critical for patient safety.
Purpose of the Study:
- To investigate patient, provider, and device-related factors associated with peripherally inserted central catheter (PICC)-associated deep vein thrombosis (DVT).
Main Methods:
- Retrospective cohort study of 966 adult PICC placements (June 2009-June 2012).
- Symptomatic PICC-associated DVT and lower-extremity DVT were confirmed by ultrasound.
- Multivariable logistic and Cox-proportional hazards regression analyses were employed.
Main Results:
- 42 thrombotic events occurred; 33 were PICC-associated DVT and 9 were lower-extremity DVT.
- Recent cancer diagnosis (OR 1.95) and larger PICC gauge (5-Fr HR 2.21, 6-Fr HR 3.56) were significantly associated with PICC-DVT.
- Interventional radiology placement, chemotherapy, and number of lumens showed association on bivariate analysis.
Conclusions:
- Recent cancer diagnosis and larger PICC gauge (5-Fr and 6-Fr) are independent risk factors for PICC-DVT.
- These findings highlight the need for improved policies regarding PICC selection in cancer patients and the use of larger gauge devices to mitigate thrombosis risk.

01:29Venous Thrombosis III: Interprofessional Care
482
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

01:30Venous Thrombosis I: Introduction
822
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
469
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

415
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

2.0K
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

01:19Pulmonary Embolism I: Introduction
39
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
