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.
Those with a G at both copies of rs1800497 were 1.6 times more likely to experience PONV within six hours of surgery compared to those with the AG or AA genotypes, but they were not significantly more likely to experience PONV more than six hours after surgery. [2] PONV results from patient, surgical, and anesthetic factors. [citation needed]
PDPH is a common side effect of lumbar puncture and spinal anesthesia. Leakage of cerebrospinal fluid causes reduced fluid pressure in the brain and spinal cord. Onset occurs within two days in 66% of cases and three days in 90%. It occurs so rarely immediately after puncture that other possible causes should be investigated when it does. [3]
A study by Newman et al. at Duke University Medical Center showed an increased incidence of cognitive decline after coronary artery bypass surgery (CABG), both immediately (53 percent at discharge from hospital) and over time (36 percent six weeks, 24 percent at six months, and 42 percent at five years).

The incidence of emergence delirium after halothane, isoflurane, sevoflurane or desflurane ranges from 2–55%. [10] Most emergence delirium in the literature describes agitated emergence. Unless a delirium detection tool is used, it is difficult to distinguish if the agitated emergence from anesthesia was from delirium or pain or fear, etc.

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]
Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...
