Brief Summary

Postoperative nausea/vomiting (PONV) is a common problem following surgery and anesthesia. There are risk factors that increase the incidence of PONV that are related to the patient, to the surgical procedure or to the anesthetic agents. At the subjective level PONV is described as worse and more feared than postoperative pain by many patients. At the objective level it increases the length of stay in the recovery room, it results in unplanned hospital admission and Emergency Room visits, and therefore increased cost of care. A lot of research work has been done to identify pharmacological agents to prevent and treat PONV. The higher the risk of a patient the higher number of these drugs are combined for prophylaxis. However, these drugs have significant side effects of their own. Much less attention has been paid to potential non-pharmacological PONV prevention options. The purpose of our study is to investigate the putative role of the natural stimulation of normal gastrointestinal function via the Pavlovian reflex. We seek to find a natural method with no side effects to improve PONV prophylaxis in patients with risk factors for that postoperative complication.

Outcome Measures

Primary Outcomes (2)

  • Change of the incidence of postoperative vomiting

    The number of the episodes of emesis will be counted and recorded in the patients' records.

    Immediately postoperative

  • Change of postoperative anti emetic drug administration

    The type and dose of administered antiemetic drugs will be recorded and analyzed in the patients' charts.

    Immediate postoperative

Secondary Outcomes (1)

  • Change of recovery room length of stay

    Immediate postoperative

Study Arms (2)

Study group

EXPERIMENTAL

The study group will watch 15 minute long videos of cooking and preparing the food of the patient's preferred type of food prior to be taken to the operating room.

Other: Visual exposure to taped food preparation

Placebo group

PLACEBO COMPARATOR

The control group will watch 15 minute long non-food related videos.

Other: Visual exposure to topics not related to food

Interventions

Patients in the study group can watch the preparation of the the type of food she prefers to eat normally.

Study group

Patients in the placebo group can choose a video that is relaxing but not related to food.
