All 4 faces pain scales were found to be adequately supported by psychometric data .
When given a choice between faces scales , children preferred the WBFPRS .
Confounding of pain intensity with affect caused by use of smiling and crying anchor faces is a disadvantage of the WBFPRS .
: For clinical use , we found no grounds to switch from 1 faces scale to another when 1 of the scales is in use .
CONTEXT : Numerous faces scales have been developed for the measurement of  pain intensity in children .
It remains unclear whether any one of the faces scales is better for a particular purpose with regard to validity , reliability , feasibility , and preference .
OBJECTIVES : To summarize and systematic ally review faces pain scales most commonly used to obtain self-report of pain intensity in children for evaluation of reliability and validity and to compare the scales for preference and utility .
Development of a research-based standard for assessment, intervention, and evaluation of pain after neonatal and pediatric cardiac surgery.
This analysis of retrospective and prospect i ve data quantified children ( age range 0 - 18 years , total n = 132 ) during their stay in a cardiothoracic intensive care unit and examined pain management and sedation practice s. Data on both factors that could potentially affect pain and its management , and analgesics/sedatives ordered for and administered to subjects were collected from chart review . In the prospect i ve group , pain intensity was measured twice daily using the Wong-Baker FACES Pain Rating Scale . Repeat cardiac surgical procedure subjects reported significantly more pain than nonrepeat subjects on the first postoperative night . Subjects with sternal incisions  reported significantly more pain than subjects with submammary incisions . Not all subjects were premedicated with analgesia for invasive procedures . Significantly greater amounts of analgesia were received by the 0 - 3 year-old subjects . Large amounts of  sedation  were used , especially in children under 3 years of age . The results prompted development of a nursing st and ard to assess and manage pain and sedation in this population
