Study Notes
Complications Associated with Blood Collection
- Edema: accumulation of fluids in the tissues
- Hematoma: leakage of blood from vessels during venipuncture
Vascular Access Sites and Devices
- Arterial Line
- Arteriovenous shunt or Fistula
- Blood-sampling Device
- Heparin or Saline Lock/ “hep-lock” for medicine administration or blood sampling
- IV Sites: phlebotomist should collect below IV lines
- Central Vascular Access Devices (CVADs)/ Indwelling lines: central venous catheter lines, implanted port, peripherally inserted central catheter
Handling Patient Complications
- Allergies to Equipment and Supplies:
- Adhesive allergy: apply gauze for 15 mins
- Antiseptic allergy: use a different antiseptic technique
- Latex allergy: use non-latex gloves, tourniquet, bandages
- Excessive Bleeding: apply pressure until bleeding stops
- Fainting: lie down during procedure
- Nausea and Vomiting: discontinue procedure until patient feels better
- Pain: if patient complains of extreme numbness or pain, remove needle and apply ice to site (may indicate nerve involvement)
- Phlebotomist should only extract required volume from patient, as 10% loss of blood can threaten patient
Inadvertent Complications
- Inadvertent Arterial Puncture: rapid filling of tube, rapid formation of hematoma on site
- Infection: maintain sterile conditions, keep veni site closed for 15 mins
- Nerve Injury: improper site selection, rapid needle insertion, excessive redirection of needle, blind probing
- Reflux of Anticoagulant: downward position, tube below veni site
- Vein Damage: follow proper techniques, avoid blind probing
Specimen Quality
- Hemoconcentration: decrease in fluid content or plasma volume caused by tourniquet that stagnates blood flow
- Hemolysis: rupture of RBCs, release of Hgb into surrounding fluid
- Partially-filled tube or short draw: incorrect blood-to-additive ratio
- Specimen contamination
- Wrong or Expired Collection tube
Troubleshooting Failed Venipuncture
- Needle position is critical to success
- Petechiae: small red or purple spots that resemble rashes when tourniquet is applied
- Seizures or convulsions: discontinue procedure, check mouth for obstruction, protect patient from self-injury, notify first aid personnel
Avoiding and Handling Procedural Errors and Failure to Draw Blood
- Hematoma Formation:
- Hold pressure over site immediately after discontinuing draw
- Cold compress or ice pack may help address swelling
- Conditions that trigger hematoma include: excessive or blind probing, inadvertent arterial puncture, small vein size, needle penetration through vein, incomplete needle insertion, tourniquet still on when needle removed, inadequate pressure
- Iatrogenic Anemia: blood loss due to blood draw
