Post-operative nausea and vomiting
Post-operative nausea and vomiting is a common port-operative complication in a surgical and anesthetic environment, affecting 25 – 30% of the low risk patients and up to 70 – 80% of the high risk patients. In addition to the discomfort that it generates in the patients, it determines a greater post-operative morbility from hydroelectrolytic alterations and bronchial aspiration risk. Likewise, a Valsalva phenomeon increases the tension on the line of sutures, favoring hematoma formation and dehiscence.
On the other hand, the rise generated by health care costs is also important since 76 – 78% of outpatients consider nausea and vomiting, respectively, an important post-operatory factor to be eliminated.
There are few studies that show the association of risk factors separate from post-operative nausea and vomiting episodes; however, among the most named are gender, being a smoker, kinetosis (motion sickness), type and length of the surgery, anesthesia drugs used and pre- and post-operatory pain treatment.
