The surgeon will have to get into the patient’s room, where a sedative will be administered to the patient with an understanding of how severe heart disease and other conditions affect them. The patient is placed in a medically-induced coma so blood loss from a large heart attack can be controlled. The patient will have a balloon catheter inserted, which contains blood. This type of surgical task has the potential to produce a blood loss in the patient. The first example of a surgical asepsis case is a brain surgery.Īn example of a surgical asepsis case is a cardiology surgical procedure that deals with patients with pre-existing cardiovascular problems. Knowing what is expected during the surgical task means they will be able to properly control the amount of blood lost in a surgical situation.

Varicella, disseminated herpes zoster, and hemorrhagic fevers with pneumonia also call for contact precautions.The examples of medical and surgical asepsis are used to show surgeons how to control blood loss in the clinical setting. Airborne precautions are indicated for patients with suspected or confirmed infectious pulmonary or laryngeal tuberculosis measles varicella disseminated zoster and Lassa, Ebola, Marburg, and other hemorrhagic fevers with pneumonia.
Airborne precautions include wearing an N95 respirator, placing the patient in a single room that is under negative pressure of 2.5 Pain relation to adjacent areas, keeping the door closed, providing a minimum of 6 to 12 air changes per hour, and exhausting room air outside the building and away from intake ducts or through a high-efficiency particulate air (HEPA) filter if recirculated. The NNIS system has been used to develop indices for predicting the risk of nosocomial infection in a given patient.Īirborne precautions are designed to reduce transmission of microorganisms spread via droplets that have nuclei 5 µm in size or smaller, remain suspended in air for prolonged periods of time, and have the capability of being dispersed widely.
The Centers for Disease Control and Prevention (CDC) established the National Nosocomial Infections Surveillance (NNIS) system in 1970 to create a national database of nosocomial infections. In most institutions, the responsibility for classifying the incision site is assigned to the operating room circulating nurse one assessment suggests that the accuracy of decisions made by this group is as high as 88%.
Operative wounds are susceptible to varying levels of bacterial contamination, by which they are classified as clean, clean-contaminated, contaminated, or dirty. A comprehensive study determined that there is considerable variation in the timing of administration of prophylactic antibiotics, but that the administration within 2 hours before surgery reduces the risk of SSI. Antimicrobial prophylaxis is also indicated for clean operations in which an intra-articular or intravascular prosthetic device will be inserted and for any operation in which an SSI would have a high morbidity. Antimicrobial prophylaxis is used for all operations that involve entry into a hollow viscus.
Lower infection rates were reported with the use of depilatory agents and electric clippers than with razors. The influence of hair removal methods on SSI has been examined by many investigators.

These include method of hair removal (and likelihood of consequent skin injury), inappropriate use of antimicrobial prophylaxis, duration of the operation, and wound classification. Several factors related to the operative procedure may be associated with the risk of development of an SSI.
