Vomiting has been associated with major complications, such as pulmonary aspiration of gastric content, and might endanger surgical outcomes after certain procedures, for example after maxillofacial surgery with wired jaws. Nausea and vomiting can delay discharge, and about 1% of patients scheduled for day surgery require unanticipated ...
Perioperative mortality has been defined as any death, regardless of cause, occurring within 30 days after surgery in or out of the hospital. [1] Globally, 4.2 million people are estimated to die within 30 days of surgery each year. [2]
Postanesthetic shivering is one of the leading causes of discomfort in patients recovering from general anesthesia. It usually results due to the anesthetic inhibiting the body's thermoregulatory capability, although cutaneous vasodilation (triggered by post-operative pain) may also be a causative factor.
The original scoring system was developed before the invention of pulse oximetry and used the patient's colouration as a surrogate marker of their oxygenation status. A modified Aldrete scoring system was described in 1995 [2] which replaces the assessment of skin colouration with the use of pulse oximetry to measure SpO 2.
[2] [4] Most infections are present within the first 30 days after surgery. [5] Surgical wounds can become infected by bacteria, regardless if the bacteria is already present on the patient's skin or if the bacteria is spread to the patient due to contact with infected individuals. [ 5 ]
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.
After surgery, recognition of the symptoms of an awareness event may be delayed. [11] One review showed that only about 35% of patients are able to report an awareness event immediately after the surgery, with the rest remembering the experience from weeks to months afterward. [ 12 ]
Of the 578 patients who died, 404 (69.9 percent) did so between 24 hours and 30 days following surgery (high 74.2 percent, middle 68.8 percent, low 60.5 percent). Patient safety factors were suggested to play an important role, with use of the WHO Surgical Safety Checklist associated with reduced mortality at 30 days.
