wound,drain,defense
wound healing,drainage and body defense
| Question | Answer |
|---|---|
| adhesion | union of 2 surfaces or structures that are normally separate |
| allergen | any substance that brings on the manifestations of an allergy |
| allergy | abnormal hypersensitivity by an individual to 1 or more substance |
| antigen | a substance which induces the formation of antibodies; may be introduced into the body or formed w/in the body |
| antitoxin | an antibody capable of neutralizing a specific toxin |
| attenuated | less virulent; diluted; weakened |
| cicatrix | scar left by a healed wound |
| clean-contaminated | primary closure, wound drain, minor break in aseptic technique occurred. no inflammation |
| clean | |
| closed | skin is intact, but underlaying tissue is injured |
| collagen | white protein contained in the connective tissues and bones |
| contaminated | open fresh traumatic wound of less than 4 hrs old or major break in aseptic technique |
| debridement | removal of foreign material; cutting away dead/devitalized tissues; open, clean wound where anaerobic organisms cannot survive |
| dirty & infected | old traumatic wound over 4 hrs old, from a dirty source or the presence of neuroic tissue, fecal matter |
| disruption | when the orderly closure of a wound is altered; usually suture lines break down, decreasing support of abdominal wall over peritoneal contents |
| endotoxins | bacterial toxins which are liberated only when the bacterial cell is destroyed |
| fibrinogen | constituent of blood that aids in coagulation |
| granulation | formation of new tissue, composed largely of newly growing capillaries which form in types of wounds left open |
| granulation tissue | fibrous connective tissue containing blood vessels and lymphatics; not visible in 1st intention healing |
| hemotoma | tumor or swelling which contains blood |
| hemostasis | control of bleeding |
| immune response | the production of antibodies in response to the presence of a corresponding antigen |
| immune | not susceptible or responsive to a disease or having a high degree of resistance to a disease |
| immunization | process of rendering a patient immune |
| ischemia | decrease of blood supply to tissue |
| keloid | dense, unsightly connective tissue or excessive scar fromation; removed surgically |
| macrophage | type of WBC's the engulfs |
| necrosis | death of tissue cells |
| open, clean | skin is broken & the object or condition surrounding the injury are relatively clean |
| open, complicated | skin/underlying tissue are injured or destroyed by crushing, burning or implantation of a foreign object |
| open, simple | skin is broken, but the underlying tissue is uninjured |
| sero-sanguinous | blood-tinged or colored serous drainage |
| serum | watery fluid taken from the blood of an animal rendered immune against a pathogenic organism which is injected into a pt to protect against the disease resulting from a pathogenic organism |
| surgical incision | caused by a purposful cut thru intact skin |
| toxin | a poisonous substance |
| toxoid | a toxin treated so as to destroy its toxicity, but still capable of inducing formation of antibodies on injection |
| trauma | injury to body tissue produced by violence of any chemical, thermal or other extrinsic agent |
| traumatic injury | caused by chemical, thermal or other factors |
| vaccination | inoculation w/a vaccine |
| vaccine | suspension of infectious agents given to establish resistance to an infectious disease |
| 1st intention healing | healing is by primary union |
| 2nd intention healing | wound is not closed |
| 3rd intention healing | similar to second intention healing except wound is sutured, either delayed or secondary |
| 2nd or 3rd intention healing | healing may produce a weak union, which may be conducive to incisional heriation later |
| basic types of wounds | chronic wound, surgical incision, traumatic injury |
| clean wound | elective procedure; wound made under ideal conditions, primary closure, no drain, no breaks in aseptic tech, no inflammation, alimentary, genitourinary or resp. tract or oropharyngeal cavities are not entered |
| contaminated wound | open fresh traumatic wound less than 4 hrs old, 1-5% infection rate, acute, nonpurulent inflammation present, entry into biliary or genitourinary tracts w/infected bile or urine present |
| puncture | a hole, wound, or perforation made by puncturing |
| laceration | a torn and ragged wound w/irregular edges |
| healing & pt physical condition | wound healing is impaired by deficiencies in zinc, protein, carbohydrates & vit. a,b,c; radiation in large doses preoperatively slows the healing process; carbs are necessary in healing |
| eventration | partial protrusion of the abdominal contents thru a opening in the abdominal wall |
| antibody | protein substance developed by the body in response to the presence of an antigen that counteracts the antigen |
| immunology | study of the immune system |
| artificially acquired passive immunity | antibodies produced elsewhere are injected in the form of immune serums |
| bougie | instrument for exploring and dilating canals, especially the male urethra & the esophagus |
| drain | exit for discharge of abnormal fluid accumulations or to draw off fluid |
| lumen | hollow opening thru a tube or catheter |
| catheters | use to allow a method for insulation, drainage, irragation & medication |
| drains | used to prevent hematomas; may be placed in the cavity and exteriorized thru a seperate stab wound |
| tubes | used to decompress the GI tract |
| Penrose drain | uses capillary action as the drainage mechanism |
| T-tube | used for common bile duct exploration |
| levine tube | single lumen tube used for gastric decompression connected to gravity drainage or intermittent suction |
| 3 primary parts of a tracheostomy tube | obturator, outer cannula tube, inner cannula tube |
| pharyngeal airway tube | is inserted thru the mouth |
| chest tube | is not used to drain esophageal abscesses; are always connected to an underwater seal drainage system |
| pleur-evac | is a self-contained drainage system units |
| common inhalant allergen | dust,perfume,pollen,chocolate,plants,fur |
| symptoms of acute inflammatory response | redness,heat,swelling,pain & disordered function |
| treatment of acute inflammation | rest the inflammed part, open drainage to allow bacteria to escape & to relieve tension & swelling of inflamed part; supplement body's natural defenses w/specfic drugs such as antibiotics |
| genetic immunity | is programmed into one's genetic makeup |
