2) Confirm pre-surgical instructions (NPO? Surgery release form?)
3) Obtain blood work/lab results, body wt.
4) Examine (Pre-existing health problems, vaccinations
5) Report abnormal behavior, any results from above tasks to DVM before you begin prepping

84
What circulator can do
Will have mask and cap on, clean OR, set up the Sx table, collect all necessary surgical supplies, drape the back up table, assist the scrub nurse, pt prep, clean the OR after, attach suction and cautery cord to machine, mediator between sterile and non sterile feilds
85
What scrub nurse can do
Will have mask and cap on, help gown and glove surgeon, attach cauter and or suction tip, pass instruments, mediator between sterile and sterile feilds, clean OR before and after, drape mayo stand,
86
Incision
A wound made aseptically by a scalpel or cautery in a prepard site. Closure is performed easily, and first intention healing occurs due to the close correct approximation of the tissue
87
Laceration
An accidental wound created in a contaminated matter (irragular tear of flesh). Closure could be difficult, infection very possible, could be secondary or third intention. Less than 6rs old is golden time to fix
88
Puncture
A hole or wound made by sharp pointed object usually teeth. Often close easily, but usually never benaficial due to bacteria its better to leave it open to drain
89
First intention healing
Healing usually follows the initial suturing of incised and correct closed wound. Usually fast with no complications, little scare tissue. "side to side" healing.
90
Second intention healing
Wounds that failed to heal or should not be healed by first intention due to: infection, excessive trauma, loss of tissue, inadaquate approximation. Causes scare tissue and area will not grow back hair. Granulation tissue (proud flesh)
91
Third intention healing/delayed primary closure
The surgeon waits 3-5 days after injury to close the wound, granulation tissue must be present and no signs of infection. Surgeon will then debride the wound and suture with primary closure
92
Secondary closure
Can be done up to 1 month after initial wound. Heals by second intention, the granulation tissue is removed and the wound is resutred with primary closure. Rids wound of infection, creates healthy tissue and reduces scar tissue
93
Dihiscence
Partiale seperation of a wound that has been healing before complete healing has occured
94
Antiseptic
Chemicals used to inhibit or prevent the growth of microbes on living tissue
95
Disinfectant

Bleach, roccal, rescue, betadine, chlorahexadine
106

Bleach but only slightly
107
What four factors prevented the developmentof surgery until the industrial revolution?
Knowledge of anatomy, inability to cause hemostasis, anesthesia, aseptic techneques
108
Ambroise Pare
French army surgeon. Started using emollient of egg yolk, rose oil, turpentine to cauterize wounds instead of boiling oil. learned to ligate blood vessels with silk sutures. Considered father of hemostasis
109
Ignaze Semmelweiss
Instructed doctors to wash hands and death/infection rates decreased. His work was largly unappreciated
110
Louis Pasteur
Biogenesis replaced spontanious generation. Isolated microorganisms, developed lab techneques still used today. Worked on chicked cholera, applied knowledge to improving anthrax vaccine (cattle), developed vaccine & post exposure treatment for rabies.
111
Joseph Lister
Inspired by Pasteur's work lead him to spraying instruments, incisions, and dressings with carbonic acid. Had sureons wear clean gloves and wash hands before and after surgery using 5% carbonic acid
112
