Hemostasis
Hemostasis
used to compress the walls of vessels and to graps tissue
clamps/hemostat
biological adhesive and hemostatic agent consist of fibrinogen, cryoprecipitate derived from human plasma, calcium chloride and thrombin
fibrin glue
antigenic substance found in erythrocytes in most people
Rh factor
enhances blood's clotting ability when platelet count is low
Platelets
patient's blood loss is monitored intraoperatively to aid the surgeon and anesthesia care provider in making decisions regarding the patients status and potential need for intervention.
transfusion/autotransfusion
strands of suture material used to tie off blood vessels
Ligatures/ties
most commonly used thermal hemostatic device
electrosurgery
most common type of homologous blood replacement therapy used in the OR
packed red blood cells (PRBC's)
platelets adhere to subendothelium of vessel walls
first phase of clotting process
the amount of irrigation fluid used subtracted from the total volume of fluids provides what accurate measurement
Blood loss
Used in place of suture ligatures when many small vessels need to be ligated in a short period of time
Clips
Lasers
used to treat trauma-induced hemorrhage
Whole Blood
This enhances the suture knot's security
the tail
Preoperative testing is useful in determining this condition
hemophilia
bleeding occurs through needles holes in vessel anastomosis, small squares of Teflon
pledgets
vibrations of the blade denature protein molecules within the tissue producing a sticky coagulum that seals the vessels
Ultrasonic Harmonic Scalpel
patient's own blood, donated prior to surgery or collected and reinfused intraoperatively
autotransfusion
electricity is not required to produce the cutting and coagulation, grounding pad not needed
Ultrasonic Harmonic Scalpel
liver disease, anticoagulant therapy with heparin or warfarin sodium and aplastic anemia
acquired bleeding disorders
external pressure to a vessel, , occlude the flow of blood until a clot has formed, prophylactically, sequential stockings, prevent venous stasis and DVT
mechanical pressure devices
Gelfoam, Avitene, Silver nitrate, Epinephrine, Thrombin
Chemical Hemostasis
Hemolytic Transfusion Reactions
blood that is collected intraoperatively from a wound then washed
