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 .
Unsedated upper endoscopy in children.
BACKGROUND EGD is essential to the investigation and treatment of GI disorders in children . Although safe , EGD has the potential for complications , in particular cardiopulmonary abnormalities associated with intravenous sedation . EGD is often performed in adults without sedation . Unse date d EGD is occasionally performed in children but has not been subjected to study . This study assessed the safety , efficacy , and feasibility of unse date d EGD in children . METHODS Selected , highly motivated children requiring EGD were offered the choice of sedation or no sedation for the procedure . Children recorded scores for pain ( face scale ) and anxiety ( vertical visual analogue scale ) before and after EGD . In addition , the times required to prepare the patient , perform the EGD , and recover the patient were recorded . RESULTS There was no difference in age , gender , or pre-EGD pain scores between children selecting sedation or no sedation . However , children selecting sedation had significantly higher pre-EGD anxiety scores than those who chose no sedation . Successful completion of EGD was similar for se date d ( 96.3 % ) and unse date d ( 95.2 % ) children . Post-EGD scores for anxiety were significantly decreased in those receiving sedation and unchanged in children who received no sedation . There was no significant change in post-EGD pain score in either group . Nearly 80 % of children undergoing unse date d EGD would elect to forego sedation if EGD was needed again . Total procedure time was significantly longer in se date d versus unse date d children , reflecting longer preparation and recovery . CONCLUSIONS Unse date d EGD can be performed safely and successfully in children with good patient tolerance . There was a significant decrease in total procedure time for children who have unse date d EGD . Unse date d EGD should be considered a viable option for motivated children
