Cotinine has an in vivo half-life of approximately 20 hours, and is typically detectable for several days (up to one week) after the use of tobacco. The level of cotinine in the blood, saliva, and urine is proportionate to the amount of exposure to tobacco smoke, so it is a valuable indicator of tobacco smoke exposure, including secondary (passive) smoke.

Cotinine: Cotinine, a metabolite of nicotine, is present in smokers. Like carbon monoxide, a cotinine test can be a reliable biomarker to determine smoking status. [114] Cotinine levels can be tested through urine, saliva, blood, or hair samples. One of the main concerns of cotinine testing is the invasiveness of typical sampling methods.
Myocardial injury after non-cardiac surgery, also known as MINS, refers to at least one elevated post-operative troponin level presumed to be of an ischemic mechanism. [ 1 ] [ 2 ] There is an absence of any overt non-ischemic causes to explain this elevation.

A patient taking anticoagulants—aspirin, clopidogrel, ticagrelol and others—will stop taking them several days before, to prevent excessive bleeding during and after the operation. Warfarin is also stopped for the same reason and the patient starts taking heparin products after the INR falls below 2.0.
Postoperative fever refers to an elevated body temperature (≥ 38.5 °C) occurring after a recent surgical procedure. Diagnosing the cause of postoperative fever can sometimes be challenging; while fever in this context may be benign, self-limited, or unrelated to the surgical procedure, it can also be indicative of a surgical complication, such as infection.
