SR 20 - Surgical Hemostasis Flashcards
What motto is associated with surgical hemostasis?
‘All bleeding stops’
What is the most immediate method to obtain hemostasis?
Pressure with your finger
What is the ‘Bovie’?
Electrocautery
Designed by Bovie with Cushing for neurosurgery in the 1920s
What is the CUT mode on the Bovie?
Continuous electrical current (20,000Hz)
Cuts well with a decreased ability to coagulate
What is the COAG mode on the Bovie?
Intermittent electrical current (20,000hz)
Results in excellent vessel coagulation with decreased ability to cut
Where should a Bovie be applied to a clamp or pick-up to coagulate a vessel?
Anywhere on the clamp/pick-up
Should you ever ‘blindly’ place a clamp in a wound to stop bleeding?
No - you my injure surrounding tissues such as nerves
Define - Figure-of-eight suture
Suture ligature placed twice in the tissue prior to being tied
Define - Vessel ‘tied in continuity’
Tie, tie, cut in between (like you do with hemo clips - versus clamp, clamp, cut, tie, tie)
Define - Surgicel
Cellulose sheets
Acts a a framework for clotting factors and platelets to adhere to
Define - Fibrin glue
Fibrinogen and thombin sprayed simultaneously and mixed to produce a fibrin ‘glue’
Define - Harmonic scalpel
Ultrasonic scalpel that vibrates >50,000 times per second
Seals vessels and cuts tissue
Define - Clips
Metallic clips for clipping vessels
