According to the American College of Cardiology, atrial fibrillation occurs after aortic valve replacement surgery at a rate of about 12%, making it the most frequent cardiac arrhythmia. Acute or late onset atrial fibrillation raises the risk of stroke and mortality in people affected.
Safety requirements for wrapping materials used during sterilization include resistance to tears, punctures, and abrasions. Other requirements include: sufficient seal integrity; aseptic delivery of contents to the sterile field; correct labeling; adequate size for even content distribution; and ability to maintain the sterility of contents until opening. Other requirements also include: sufficient porosity to allow for steam or gas penetration and venting; effective air and microorganism barrier; effective moisture resistance (not water-proof); absence of toxic ingredients and non-fast dyes; absence of moisture-sensitive materials; and absence of toxic ingredients.
Like sewing thread, suture is sized according to gauge. #11-0 is the smallest gauge while #5 is the largest. #1-4-0 are the sizes that are most frequently used.
After heart surgery, Plavix is typically stopped within 48 hours. Five to seven days before surgery, patients should cease taking warfarin, often known as Coumadin. Aspirin normally doesn't need to be stopped before this surgery, however diuretics like Lasix should be stopped the morning of the procedure.
Only the internal ties may be touched by the circulator or other nonsterile team members while dressing the surgeon because they are the only ones that are not in contact with the outer sterile area of the gown.
The Perioperative Patient Focused Model is divided into four quadrants. One relates to the healthcare facility where the care is being administered, and three are patient-focused.
To prevent microbiological penetration, the draping materials must form a barrier and be fluid resistant as well as tear- and puncture-resistant. To lessen airborne contaminants and shedding into the surgical site, a sterile drape should be lint-free.
