Risk Factors
Postoperative nausea and vomiting results from anaesthesic, surgical, and patients factors. Gynaecological, urological, strabismus correction and middle ear surgery all have a higher risk of postoperative nausea and vomiting.
Patients that are female or who have a history of postoperative nausea and vomiting are at greater risk. Smokers have a decreased risk, but this would never be recommended by any physician. Older patients suffer less PONV.
Obesity, age less than 16 years, past history of motion sickness and high levels of pre-operative anxiety are also risk factors for PONV.

—Robert Hewison (b. 1943)
“The economic dependence of woman and her apparently indestructible illusion that marriage will release her from loneliness and work and worry are potent factors in immunizing her from common sense in dealing with men at work.”
