Central Venous Catheter Removal
PREREQUISITE NURSING KNOWLEDGE
• Knowledge of the normal anatomy and physiology of the vasculature and cardiovascular system is necessary.
• Knowledge of normal coagulation values is needed.
• Principles of aseptic technique should be known.
• Advanced cardiac life support knowledge and skills are necessary.
• Clinical and technical competence in central venous catheter (CVC) removal is necessary.
• Knowledge of the state nurse practice act is important because some states do not allow this intervention to be performed by a registered nurse.
• Knowledge of potential complications associated with the removal of the CVC is needed.
• An air embolism can occur during or after the removal of the catheter as a result of air drawn in along the subcutaneous tract and into the vein. During inspiration, negative intrathoracic pressure is transmitted to the central veins. Any opening external to the body to one of these veins may result in aspiration of air into the central venous system. The pathologic effects depend on the volume and rate of air aspirated. Signs and symptoms include: respiratory distress, agitation, cyanosis, gasp reflex, sucking sound, hypotension, petechiae, cardiac dysrhythmias, and altered mental status.
EQUIPMENT
• Face mask, sterile glows, nonsterile gloves
• Antiseptic solution (e.g., 2% chlorhexidine-based preparation)
Additional equipment to have as needed includes the following:
PATIENT AND FAMILY EDUCATION
• Explain the procedure to the patient and family and the reason for catheter removal. Rationale: This explanation provides information and decreases anxiety.
• Explain the importance of the patient lying still during the catheter removal. Rationale: This explanation ensures patient cooperation and facilitates safe removal of the catheter.
• Instruct the patient and family to report any signs and symptoms of shortness of breath, bleeding, or discomfort at the site of catheter removal. Rationale: Identifies patient discomfort and early recognition of complications.
PATIENT ASSESSMENT AND PREPARATION
Patient Assessment
• Assess vital signs and the neurovascular status of the extremity distal to the catheter insertion site. Rationale: This assessment provides baseline data.
• Assess the patient’s current coagulation values. Rationale: If the patient has abnormal coagulation study results, hemostasis may be difficult to obtain.
• Assess the catheter site for redness, warmth, tenderness, or presence of drainage. Rationale: Determines if signs or symptoms of infection are present.
Patient Preparation
• In collaboration with the physician, determine when the CVC should be removed. Rationale: The invasive catheter is removed when it is no longer indicated.
• In collaboration with the physician, determine whether the tip of the catheter will be cultured. Rationale: This discussion determines additional supplies that may be needed.
• Verify correct patient with two identifiers. Rationale: Prior to performing a procedure, the nurse should ensure the correct identification of the patient for the intended intervention.
• Ensure that the patient and family understand preprocedural teaching. Answer questions as they arise, and reinforce information as needed. Rationale: Understanding of previously taught information is evaluated and reinforced.
• Place the patient in a supine position with the head of the bed in a slight Trendelenburg’s position (or flat if Trendelenburg’s position is contraindicated or not tolerated by the patient). Rationale: A normal pressure gradient exists between atmospheric air and the central venous compartment that promotes air entry if the compartment is open. Placing the patient in a head-down position decreases the risk of air being drawn into the venous circulation.
• Start a new peripheral intravenous (IV) line or ensure that an existing peripheral IV line is patent. Rationale: IV access is established for fluids or medications.
