Complications Related to Use of Heart and Lung Machine: Infection and Sepsis Risk
The use of a heart-lung machine in cardiac surgery or other medical procedures can pose various risks to patients. Infection and sepsis risk is a critical complication that can arise from the machine’s components and the patient’s exposure to the device.
The heart-lung machine is a complex device that involves various components, such as the oxygenator, pump, and tubing. Each of these components can contribute to the risk of infection and sepsis. The oxygenator, for instance, can harbor bacteria and other microorganisms, which can be introduced into the patient’s bloodstream during the procedure. Similarly, the pump and tubing can provide a conduit for bacteria to enter the patient’s body.
Risk Factors Associated with Infection and Sepsis
- The type of bacteria present on the machine’s components can contribute to the risk of infection. Bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa are commonly found on medical devices and can cause infections in patients.
- The duration of the procedure and the number of patients exposed to the machine can also increase the risk of infection. The longer the machine is in use, the greater the risk of bacterial contamination.
- Patient factors, such as age and underlying health conditions, can also increase the risk of infection and sepsis. Older patients and those with weakened immune systems may be more susceptible to infections.
In addition to these factors, the heart-lung machine’s design and maintenance can also contribute to the risk of infection and sepsis. For instance, if the machine is not properly cleaned and disinfected between procedures, bacteria can spread from one patient to another. Similarly, if the machine’s components are not regularly tested for bacterial contamination, the risk of infection can increase.
Comparison of Infection Risk with and without the Use of a Heart-Lung Machine
It is estimated that the use of a heart-lung machine can increase the risk of infection by 2-5 times compared to traditional surgery. This is because the machine provides a conduit for bacteria to enter the patient’s body and can also increase the risk of sepsis.
In contrast, traditional surgery typically involves less risk of infection and sepsis, as the patient is not exposed to a complex medical device. However, the risk of infection and sepsis can still arise during traditional surgery, particularly if proper precautions are not taken.
