=== Key Complications ===

* '''Catheter-related bloodstream infection:''' fever, chills, elevated white blood cell count, site erythema. Obtain blood cultures from the catheter and a peripheral site, and notify the provider.
* '''Hyperglycemia''' from excessive dextrose delivery, and '''rebound hypoglycemia''' from abrupt cessation.
* '''Air embolism''' during tubing or cap changes. Signs are sudden dyspnea, chest pain, hypotension, and tachycardia. Immediately clamp the catheter, place the patient in '''left lateral Trendelenburg''' position, administer 100 percent oxygen, and call for help.
* '''Pneumothorax''' during subclavian insertion. Assess for sudden dyspnea, chest pain, and diminished unilateral breath sounds.
* '''Fluid overload''' from too-rapid infusion, particularly in heart failure and kidney disease.
* '''Hepatic complications''' including steatosis and cholestasis with prolonged use.
