Clinical utility of PPPM and FPS-R to quantify post-tonsillectomy pain in children.
OBJECTIVES As pain is a subjective and difficult parameter to assess in children , we aim ed to evaluate the correspondence of two pain scales - parents ' post-operative pain measure  ( PPPM ) and  faces pain scale-revised  ( FPS-R ) with analgesic intake in the assessment of post-tonsillectomy pain in a pediatric population . METHODS Children aged 4 - 10 years ( n=174 ) undergoing tonsillectomy with or without adenoidectomy  had their pain monitored by PPPM and FPS-R over 7 days following surgery . The amount of analgesic ( acetaminophen or dipyrone ) intake was also recorded each day . Linear regression and correlation analysis were performed for pain scales and Poisson regression model for analgesic administration . To evaluate influence of gender linear regression and logistic regression with r and om effects were performed . RESULTS PPPM and FPS-R presented a significant positive correlation ( τ=0.5 ; R(2)=0.36 ; p<0.001 ) . PPPM and FPS-R also showed a significant correlation with analgesic use over the 7 post-operative days ( p<0.0001 ) . No influence of gender was observed in pain levels by both scales . CONCLUSIONS Our data demonstrate that PPPM and FPS-R are equivalent pain scales to quantify post-tonsillectomy pain in children and are useful tools in post-tonsillectomy clinical research
