简要总结
Pediatric research in the management of nausea has been limited by the absence of a reliable method to quantify the intensity of this subjective symptom. In adults, the visual analog scale (VAS) is an accurate tool, but this has not been shown to be reliable in young children. By default the most common objective outcome measure used in pediatric studies has been the incidence and number of emetic episodes. This measure, however, correlates poorly with the somatic subjective symptom of nausea.

Pediatric research in the management of nausea has been limited by the absence of a reliable method to quantify the intensity of this subjective symptom. In adults, the visual analog scale (VAS) is an accurate tool, but this has not been shown to be reliable in young children. By default the most common objective outcome measure used in pediatric studies has been the incidence and number of emetic episodes. This measure, however, correlates poorly with the somatic subjective symptom of nausea.
Apfel et al have shown that 30-40% of adult patients undergoing surgery have post discharge nausea and / or vomiting while 12% have vomiting. These data on nausea in adults were based on a visual analog scale for nausea. There are no data on the incidence of postoperative nausea in children since the severity of symptoms are difficult to measure as younger children are known to be unable to use the VAS reliably.
Recently a pictorial scale for measuring nausea, the Baxter Animated Retching Faces (BARF) scale, has been developed and shown to have construct, content and convergent validity as an instrument to measure nausea in children. The clinical usefulness of this scale in determining the incidence of postoperative and post-discharge nausea in children has yet to be determined including the lowest age where it can be used reliably, the score associated with a patient's perception of a need for treatment, the minimum change in the scores of clinical relevance and the test-retest reliability when nausea is rated as not having changed.

结局指标
主要结局
Number of Patients With Nausea, Emesis, Severe Nausea, Severe Emesis and Number Receiving Rescue Antiemetics in the Post-Anesthetic Care Unit (PACU)
时间窗: When awake and responding to commands in the post-anesthesia care unit (PACU)
To measure pain and nausea, subjects completed the VAS and two pictorial scales (Faces Pain Scale-Revised for pain and BARF for nausea). The VAS uses a horizontal 10cm line with the extremes of "no pain at all" and "worst pain imaginable". The subject marks on the line their pain rating. Higher points indicate more severe or intense pain. FACES scale has 6 faces with assigned scores ranging from 0 to 10 with a score difference of 2 between each face (a higher score indicates more pain). The BARF scales has 6 faces with assigned scores ranging from 0 to 10 with a score difference of 2 between each face (a higher score indicates more nausea).
次要结局
- Incidence of Post-Discharge Nausea, Emesis, Severe Nausea, Severe Emesis and Number Receiving Rescue Antiemetics in Subjects Who Returned the Diary(First 24 postoperative hours)
- Age-Related Ability to Use the BARF Scale(Comprehensive)
