Preanesthetic assessment (also called preanesthesia evaluation, pre-anesthesia checkup (PAC) or simply preanesthesia) is a medical check-up and laboratory investigations done by an anesthesia provider or a registered nurse before an operation, to assess the patient's physical condition and any other medical problems or diseases the patient might have.

The group has received anecdotal reports from across the country that patients taking the drugs may be at increased risk of vomiting and aspirating food into the lungs and airways during general ...
Preoperative fasting is the practice of a surgical patient abstaining from eating or drinking ("nothing by mouth") for some time before having an operation.This is intended to prevent stomach contents from getting into the windpipe and lungs (known as a pulmonary aspiration) while the patient is under general anesthesia.

Of operative risk factors, surgical site is the most important predictor of risk for PPCs (aortic, thoracic, and upper abdominal surgeries being the highest-risk procedures, even in healthy patients. [16] The value of preoperative testing, such as spirometry, to estimate pulmonary risk is of controversial value and is debated in medical literature.
Severe systemic disease. Severe systemic disease that is a constant threat to life. A moribund person who is not expected to survive without the operation. A declared brain-dead person whose organs are being removed for donor purposes. If the surgery is an emergency, the physical status classification is followed by "E" (for emergency) for ...
General anesthesia is usually considered safe; however, there are reported cases of patients with distortion of taste and/or smell due to local anesthetics, stroke, nerve damage, or as a side effect of general anesthesia. [46] [47] At the end of surgery, administration of anaesthetic agents is discontinued.
The administration of anesthesia causes suppression of protective reflexes, most importantly the gag reflex. As a result, stomach particles can easily enter the lungs. Certain risk factors predispose individuals to aspiration, especially conditions causing dysfunction of the upper gastrointestinal system. [24]
Therapy interventions for respiratory compromise target secondary effects of the condition, which manifest as pulmonary pathologies or aggravate existing pulmonary conditions. Appropriately administered antibiotic therapy can reduce the risk of mortality in patients with moderate to severe pneumonia , and timely ventilation therapy can reduce ...
