Define the following:
Surgical Asepsis- procedure used to prevent contamination by microbes and endospores before during or after surgery using sterile technique.
Asepsis- a state of sterility; condition in which living pathogens are absent.
Medical Asepsis- reduction in the numbers of infectious agents, decreasing the probability of infection but does not necessarily reduce it to zero.
Disinfectant- chemicals used to free an environment from pathogenic organisms or to render such organisms inert.
Vector- A carrier, especially an animal that transfers an infective agent from one host to another.
Iatrogenic- resulting from the activities of physicians
Nosocomial- pertaining to the hospital; said of an infection does not present or incubating before admittance to the hospital but generally developing 72 hours after admittance.
Reservoir- alternative or passive host or carrier that harbors pathogenic organisms without injury to itself and serves as a source from which other individuals can be infected.
Fungi- general term used to denote a group of eukaryotic protists- including mushrooms, yeasts, rusts, that are characterized by the absence of chlorophyll and by the presence of a rigid cell wall.
Bacteria- prokaryotic, ubiquitous, single-celled organisms.
Fomite- an object that is not in itself harmful but is able to harbor pathogenic microorganisms and thus may serve as an agent of transmission of an infection.
Standard Precautions- precautions to prevent the transmission of disease aby body fluids and substances.
Surgical Procedures
Laparoscopic Cholecystectomy
Less invasive approach for the removal of diseased gallbladders. A small opening is made in the umbilicus, and an endoscope is passed into the abdominal cavity.
Pacemaker Insertion
Performed under local or general anesthesia in a hospital by a surgeon assisted by a cardiologist. An insulated wire called a lead is inserted into an incision below the clavicle and is guided through a large vein into the chambers of the heart. The electrodes stimulate the heart muscle causing it to beat at a predetermined rate.
Retrograde Urography
Nonfunctional examination of the urinary system. Contrast is introduced directly retrograde into the pelvicalyceal system via catherization by the urologist during a minor surgical procedure. Its frequently performed to determine the location of undetected calculi or other types of obstruction in the urinary system.
Laminectomy
Performed to alleviate pain caused by neural impingement. It's designed to remove a small portion of the bone or herniated disk material impinging the nerve root. It's intended to give the nerve root more space by removing the source of impingement or irritation.
Surgical Hardware/Devices
Cancellous Screw
Orthopedic screw designed to enter and fix porous and spongy bone
Cannulated Screw
Large screw used for internal fixation of non-displaced fractures of proximal femur
Cerclage Wire
Orthopedic wire the tightens around fracture site to reduce shortening of limb
Cortical Screw
Narrow orthopedic screw designed to enter and fix cortrical bone.
Describe the two methods of asepsis and what they entail:
Medical Asepsis- involves the reduction in the numbers of infectious agents which in turn decreases the probability of infection but does not necessarily reduce it to zero. Although the microbes are not eliminated their environment is altered so that it is not conducive to growth and reproduction.
Surgical Asepsis- is the procedure used to prevent contamination of microbes and endospores before, during and after surgery using sterile technique.
