From oneself



What refers to any type of abnormal heart rhythm

cardiac dysrhythmias


What is the act of manually providing chest compressions and ventilations to patients in cardiac arrest in an effort to provide oxygenated blood to the brain and vital organs, and reverse the processes that lead to death

cardiopulmonary resuscitation (CPR)



To apply pressure


What is the destruction of erythrocytes



What is the arrest of the escape of blood through natural or artificial means



What is a device or agent used as a coagulant



What is it called if you are from the same species



Abnormally high body temperature



What is a genetically determined blood group antigen that is present on the surface of erythrocytes of some individuals; if the antigen is present the individual is Rh1 (positive) and if absent Rh– (negative)

Rh (Rhesus) factor


What is the act of sucking up air or fluids through a device, such as a tonsil suction tip



When does the body use the process of coagulation
to achieve

hemostasis. As soon as a vessel is injured, a period of vasoconstriction begins, in which the muscular walls of the vessel constrict to help slow the flow of blood


What is the most common congenital hemostatic defect that manifests itself as a clotting deficiency.

Preoperative testing is useful in determining whether these conditions exist.


Patients may be requested not to take ...... for 1 week prior to surgery because of its anticoagulant properties.



hemostasis can be achieved with the use of several types of devices to control bleeding until a clot forms

Mechanical Methods


What are used to compress the walls of vessels and to grasp tissue



What is the most commonly used clamp

Hemostat - curved and straight jaws


What are strands of suture material (or ties, referred to as “stick ties” when a needle is attached), used to tie off blood vessels.



What are made of either natural or synthetic material and are designed either to dissolve over a period of time or to remain in the body tissue permanently



What are often used in place of suture ligatures when many small vessels need to be ligated in a short period of time.

Ligating clips


What are made of a nonreactive metal, such as titanium or stainless steel, or plastic material and come in various sizes as well as absorbable or permanent varieties. They are applied either from a manually loaded applicator or from any of several preloaded disposable applicators.



What are used to apply pressure on bleeding areas or vessels and to absorb excess blood or body fluids



What are 4 × 4’s (the size of the sponge)

Sponges (Raytec)


What is also referred to as lap sponges or “tape” sponges due to the radiopaque strand or tape that hangs from the sponge.

Sponges (Laparotomy Sponges)


What is a round sponge

Sponges (Tonsil)


What are cottonoids, are smaller compressed radiopaque sponges used for neurosurgical procedures.

Sponges (Patties)


What are dissecting sponges, which consist of small pieces of tightly rolled gauze

Sponges (Kitners and peanuts)


What is used when bleeding occurs through needle holes in vessel anastomosis, small squares of Teflon are used as buttresses over the suture line. Using suture, these are sewn over the hole in the vessel and exert outside pressure over the small needle holes to prevent bleeding and promote clotting. These are often used in peripheral vascular and cardiovascular surgery.

Not counted - stay in the patient


What is made of refined and sterilized beeswax, is used on cut edges of bone as a mechanical barrier to seal off oozing blood

Bone Wax


What is used for intraoperative aspiration of blood and body fluids by mechanical means to keep the surgical site clear



What are used postoperatively to remove blood and body fluids from the operative site to prevent edema and hematoma formation, and aid in removing air in order to prevent dead spaces within the surgical wound.



The application of external pressure to a vessel,
as with the use of a tourniquet, occludes the flow of blood until a clot has time to form.

Pressure Device (Stockings)


What may be used to prevent venous stasis and deep venous thrombosis

Prophylactically, pressure devices, such as sequential stockings,


What are often used on extremities to keep the operative site free of blood. The provision of a bloodless field makes visualization easier and reduces the operative time. Bleeding must be controlled prior to removal , however, because the use alone does not achieve hemostasis

What provides an intense and concentrated beam of light that is able to cut and coagulate tissue at the same time with very little surrounding tissue destruction.



What involves the use of argon gas in combination with monopolar electrical energy in the form of a noncontact, white light beam. It provides rapid hemostasis that travels from a generator to a pencil-like hand-piece. There is little to no tissue adherence since the hand piece does not come in direct contact with the tissue that is bleeding. There is less charring of the tissue compared to the ESU.

Argon Plasma Coagulation


What consists of a single-use titanium blade attached to a hand piece and a portable generator that cuts and coagulates tissue.
