Study Notes
Blood Collection and Restraint Procedure
-
Venipuncture (Purpose): Obtain venous blood samples for diagnostic tests (whole blood, plasma, serum).
-
Venipuncture Site Selection: Site choice is based on patient evaluation. Common sites include jugular, cephalic, transverse facial vein/sinus, and occasionally superficial/lateral thoracic vein.
-
Conditions Affecting Venipuncture: Certain conditions, like pre-existing phlebitis or severe dehydration, may affect or preclude the choice of vein.
-
Venipuncture Complications: Potential complications include minor hemorrhages, vascular trauma, perivascular hematoma formation, intravascular thrombi formation, and thrombophlebitis.
-
Equipment Needed: Gauze or cotton soaked with 70% alcohol; various gauge and length needles and evacuated tubes (e.g., 20/22 gauge, 5/8-1.5 inches); syringes.
Procedure: Venipuncture of the Jugular or Cephalic Veins
-
Vein Selection: Choose the vein based on patient condition. Locate the vein and relevant anatomical landmarks.
-
Preparation: Wash hands, clean hair and skin; wear exam gloves if applicable.
-
Venipuncture Technique: Hold the vein to impede venous return; press above and below the insertion point to distend the vein. Insert the needle at a 45° angle into the distended vein; collect blood into the evacuated tubes or syringe. Apply gentle pressure after removing the needle.
Blood Collection from Transverse Facial Vein/venous Sinus
- Landmarks: Use the facial crest, medial and lateral canthi of the eye as reference points to locate the intersection. Insert the needle at a 90° angle and advance until bone is felt.
Restraining Procedures
-
Physical Restraint: Employ a handler properly positioned on the horse's side. A chain across the nose or a twitch may be needed if the horse is uncooperative.
-
Halter Placement: To restrain, lead, and control movement. Use a halter and lead rope.
-
Tying the Lead Rope: Restrain and control horse movement.
-
Ear Fold: Brief restraint.
-
Lip Chain: Restraint method for horses with more aggressive behavior; used to restrain and redirect in conjunction with reward and negative reinforcement.
-
Nose/Lip Twitch: Used for restraint and to divert attention. Different types of nose/lip twiches exist, including rope, Kendall, and chain.
Arterial Blood Collection
-
Arteries Used: Transverse facial, facial, common carotid, dorsal metatarsal, and brachial arteries are available for this purpose.
-
Arteriopuncture Complications: Potential complications include hematoma formation, trauma/laceration, hemorrhage, contamination, difficulty in obtaining the sample.
-
Equipment Needed for Arterial Blood Collection: Gauze/cotton soaked with 70% alcohol; 20/22/25 gauge, 5/8-1.5" needles.
Additional Notes
-
Specific blood gas syringes, tuberculin syringes, and appropriate evacuated tubes are needed depending on the specific test conducted.
-
Various evacuated tubes and their additives are available for specific lab work.
-
Knowledge of the anatomical location is essential for effective blood collection.
-
Proper restraint procedures prevent injury to the horse and the person performing the procedure.
