Infusion thrombophlebitis and infection with various cannulas
Lancet (London, England)
|July 26, 1975
Summary
Longer intravenous cannulas, especially those made of Teflon, increase the risk of thrombophlebitis and bacterial contamination. Shorter infusions and avoiding long Teflon cannulas can help prevent infusion thrombophlebitis.
Area of Science:
- Medical Devices
- Infectious Diseases
- Clinical Nursing
Background:
- Intravenous (IV) cannulas are essential for drug delivery and fluid administration.
- Thrombophlebitis and bacterial contamination are significant complications associated with IV cannulas.
- Cannula material, length, and duration of use can influence complication rates.
Purpose of the Study:
- To compare the frequency of thrombophlebitis and bacterial contamination among four common types of IV cannulas.
- To evaluate the impact of cannula length and chemical composition on complication rates.
- To identify risk factors for infusion-related complications.
Main Methods:
- A prospective study design was employed.
- Four types of intravenous cannulas varying in length and material were assessed.
- Data on thrombophlebitis and bacterial contamination were collected and analyzed.
Main Results:
- Thrombophlebitis frequency significantly increased with the duration of cannula use for all types.
- Long Teflon cannulas showed significantly higher rates of bacterial contamination and thrombophlebitis compared to others.
- Shorter duration of use for butterfly stainless steel cannulas correlated with a low frequency of thrombophlebitis.
Conclusions:
- Long Teflon cannulas should be avoided to minimize complications.
- Implementing intermittent, short-duration IV infusions can potentially eliminate infusion thrombophlebitis as a clinical issue.
- Optimizing IV cannula selection and usage duration is crucial for patient safety.

01:29Blood Flow
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.
01:16Vascular Spasm
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:19Pulmonary Embolism I: Introduction
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...
01:22Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
