Central Venous Catheter (CVC)

1365 Words6 Pages

INTRODUCTION Central Venous Catheter (CVC) is a catheter placed into a large vein to obtain an intravenous access. Its use has become indispensable in the management of critically ill patients. Central venous catheters are used for hemodynamic monitoring, measurement of Central Venous Pressure, hemodialysis / plasmapheresis and in setting of difficult peripheral venous access in critically ill patients. Despite its benefits, central venous catheters have drawbacks as well. Insertion of central venous catheters can be associated with mechanical complications like arterial puncture, hematoma formation and pneumothorax and hemothorax. Late complications include catheter related bloodstream infection and catheter related local infection. Earlier …show more content…

This technique had the advantage of use of thinner bore needles, less vessel wall damage and less risk of extravasations. This technique is still the benchmark in terms of placement of the central venous lines. The use of this technique provides greater safety in internal jugular and subclavian vein cannulation. (2) It is also used in various non-vascular interventions like tumour biopsy/ embolization, percutaneous cholangiogram, percutaneous nephrostomy etc. (3) Central venous catheters can be inserted through a proximal central vein commonly the internal jugular, subclavian or femoral vein, or through a peripheral vein. The catheter is threaded through the vein till the tip reaches a large vein near the heart. The tip of the central venous catheter lies in the superior vena cava, the right atrium or the inferior vena cava. Central venous catheters are used for rapid administration of medications, fluids, blood products and parenteral nutrition to the patient. They are also used to measure central venous pressure. Central venous catheters may have up to five lumens. Central venous catheters can be associated with thrombosis, infectious complication and mechanical complications during insertion. An ideal central venous catheter should have ease of insertion, low thrombogenecity and a low rate of infectious complications. …show more content…

The preferred site of insertion of a central venous catheter depends on various factors including the skill and expertise of the operator and the availability and experience in ultrasound guided insertion of catheter. Patient related factors including risk of bleeding and pneumothorax and the urgency of placement of the central venous catheter also play a role in determining the site of insertion of the central venous

Rhabdomyolysis Case Study

I.V. fluids such as normal saline are utilized to increase volume and aid in the prevention of acute kidney injury. These I.V. fluids are initiated as soon as possible and are continued until the creatinine kinase level drops below 1,000 U/L. Diuretics such as Lasix are sometimes administered to promote the excretion of fluid. Bed rest is typically ordered for patients with rhabdomyolysis. In some cases, if compartment pressure exceeds 25 mm Hg, a fasciotomy and debridement may be

Peripherally Inserted Central Catheter Case Study Answers

I am comparing and contrasting a peripherally inserted central catheter (PICC) line, tunneled catheter and an implanted port. A PICC line is inserted into a vein in the arm rather than into the neck or chest. It is usually inserted inside of the upper arm then threaded into the larger vein in your chest. A PICC allows medications to be given that would otherwise cause damage if given in the smaller veins.

Routine IV Site Replacement Analysis

228 Words | 1 Pages

Patients that are admitted to the hospital frequently require intravenous (IV) fluids. Many hospital policies require IV sites to be changed every 72-96 hours to reduce the risk of complications caused by the IV catheter. There is increasing evidence supporting that routine IV site replacement is ineffective (Rickard, McCann, Munnings, & McGrail, 2010, p. 2). Working in the labor and delivery department, we rarely have patients that require an IV site for more than 24-48 hours.

According to Temiz et al, urinary tract infections are the most frequently encountered infections in intensive care units (2012, 344). UTIs are of special concern in ICUs because most patients in ICUs receive an indwelling urinary catheter to manage urine retention. The presence of the indwelling catheter has been identified as the most important risk factor in the development of UTIs (Temiz et al, 2012, 344). Some catheters are meant to be used only once. Many others can be re-used if cleaned appropriately.

Peripheral Intravenous Catheter

Peripheral intravenous catheter (PIVC) is the invasive procedure that most commonly practised clinical procedure. There are over half of patients admitted to the hospital required peripheral intravascular cannula (PIVC) inserted. However, there is no data reported on the use of PIVC in Malaysia. The surveillance of the estimated used of PIVC in developing countries such as Malaysia is still under evaluated due to lack of resources and trained staff. Since, PIVC required penetration of a catheter into the bloodstream, risk of catheter blood stream infection is existed.

Central Line Summary

1564 Words | 7 Pages

Although you may still have one to three lumen, like a PICC line, but instead of being inserted in the arm, central lines are “cuffed or tunneled,” meaning placed under the skin, slightly more directly to the vein near the heart. So PICC lines are in the arm or elbow, while central lines are in the shoulder, neck, and groin for location of insertion. (CENTRAL, 2015) The cleaning and maintenance of the central line is virtually the same as aforementioned above in the maintenance of the PICC lines. As is the primary function of its intended purpose of use, essentially to deliver the IV medicines, fluids, and/or blood in the most efficient way known to modern medicine.

Endovenous Laser Treatment

507 Words | 3 Pages

A catheter is guided into the affected vein using ultrasound, and a thin laser fiber is threaded into the catheter, which is then pulled out. The laser fiber is precisely placed at one end of the affected vein. Once the laser fiber is placed the full extent of the vein, heat from the laser is applied and the fiber is slowly pulled out of the vein causing the vein walls to collapse. When this happens, the blood naturally flows through healthy veins. The damaged vein is gradually absorbed by the body and disappears.

Aesthetic Obstacles Technique

With the help of the bedside nurse we analyzed why I blew two veins and a patient. I walked through the procedure to determine what I did wrong. I identified a critical flaw on my needle insertion technique. The day before I inserted the needle in a 10-15 degree angle, and after inserting the needle I leveled out the needle and pushed the needle forward until I saw blood in the catheter. At this point I pushed the catheter into the vein which led to a successful placement of an IV catheter.

In my facility, the safety of our patients is our top priority. We use a set of interventions using clinical indications to ensure the safety of patients with indwelling catheters. These indications are strict intake and output (I&O), patients monitored for acute renal insufficiency or failure, sedated patients with critical illness, and neurological patients monitored for syndrome of inappropriate antidiuretic hormone (SIADH) or diabetes insipidus. Patients suffering from acute urinary retention, or bladder outlet obstruction with the inability to void, as well as select surgical patients, are also indicated.

The circulating nurse also initiated the time-out. During the time-out, the circulating nurse said the patient’s name, the surgery that the patient was getting, and the limb in which the surgery was being performed on. The other health care professionals agreed that it was the right patient, right site, and right procedure. Throughout the surgery the circulating nurse continued to ensure the safety of the patient by watching the surgical staff and making sure that the sterile field was not contaminated. This nurse’s role also included gathering materials for the surgeon, throwing away trash, and keeping the environment comfortable for the staff.
