What is the disadvantage of a venous catheter?
While in use, the catheters may cause other complications such as infection, deep venous thrombosis (DVT), thrombophlebitis and dislodgement. Furthermore line occlusion may occur sooner or later.
What are the advantages and disadvantages of catheter?
Advantages include reduced incidence of urinary tract infection, improved comfort, and minimization of mechanical complications associated with indwelling catheter placement (see below). Disadvantages include penile injury through ulceration, scarring, and tissue ischemia.
How do you confirm placement of the femoral central line?
Use your index and middle fingers to locate the distal and proximal pulsations of the femoral artery, respectively. Just medial to your fingertips should be the general course of the femoral vein. Hence, you should puncture just medial to your index finger in a direction just medial to your middle finger.
What is the safest central line?
Subclavian access is preferable when the risk for infection is high. Because the risk for infection increases with the duration of catheter use, the subclavian approach is probably the best choice if the patient is expected to require a catheter for 5 days or more.
When should central line be removed?
Whenever central access is no longer necessary, the central line should be removed promptly.
What is a good CVP?
A normal central venous pressure reading is between 8 to 12 mmHg. This value is altered by volume status and/or venous compliance.
Can you have a CVP of 0?
As a physicist – or even our friendly neighborhood plumber – would tell you, water (and blood) flows from high pressure to low. Thus, low CVP values (including CVP = 0) may still be associated with adequate cardiac output if the upstream and downstream pressures are appropriate.
How far does a femoral central line go?
The femoral vein lies medially adjacent to the femoral artery. With increasing distance from the inguinal ligament, the vein runs under the artery. The desired point of femoral vein puncture is 1 to 2 cm inferior to the inguinal ligament.
What are the indication of femoral puncture?
The following are generally accepted indications for femoral venous catheter placement: Emergency venous access during cardiopulmonary resuscitation (CPR), in that it provides a rapid and reliable route for the administration of drugs to the central circulation of the patient in cardiac arrest.
