Study Start Date: August 2007
Study Completion Date: November 2008
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Adult same-day outpatients scheduled for general anesthesia


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Adult patients scheduled for elective outpatient surgery

Inclusion Criteria:

  • 18 years of age or older
  • scheduled for an elective outpatient surgical procedure
  • understands the nature and purpose of this survey and has signed an informed consent form
  • willing and able to complete daily components of the Patient Diary from the day of surgery until the end of the 48 hour assessment
  • undergoing general anesthesia requiring a tracheal tube or laryngeal mask airway

Exclusion Criteria:

  • planned inpatient surgery
  • inability to communicate in English
  • regional anesthesia alone without general anesthesia, as PONV in this setting is known to be significantly lower [18, 19]
  • persistent or recurrent nausea and/or vomiting before anesthesia due to other etiologies, unless clearly related only to the anxiety due to impending surgery
  • minors (< 18 years of age)
  • current pregnancy by self-report (potentially confounding for etiology of nausea)
