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 .
Comparison of oral versus rectal administration of acetaminophen with codeine in postoperative pediatric adenotonsillectomy patients.
OBJECTIVE To examine whether acetaminophen with codeine administered per rectum is an effective alternative for pain control compared with oral administration after an adenotonsillectomy . STUDY DESIGN A prospect i ve , r and omized control study . METHODS Seventy-five children aged 1 to 5 were recruited for this study . Each child was assigned r and omly to receive either rectal or oral postoperative pain medication . A journal with eight questions was kept for 10 days after the operation , and an overall survey of five questions was filled out at the first postoperative visit . RESULTS Postoperative pain was adequately controlled in those patients receiving suppositories when compared with those patients receiving oral pain medication .  Adverse effects and total number of doses given per day were similar . Parents found the suppositories easy to administer , and more parents would switch or consider switching from oral pain medication to suppositories if given the choice . CONCLUSIONS The suppositories achieved equivalent pain control as oral medication with few side effects and good tolerance . Furthermore , many parents preferred the suppositories to oral medication in maintaining postoperative pain control because of ease of administration . If given the choice for future surgeries , many parents would switch or consider switching from oral pain medication to suppositories
