Pediatric procedural pain.

Lecavalier et al. (2006) wrote a story-style review about measuring and treating pain kids feel during medical tests.

They looked at three ways to check pain: ask the child, watch the child, and track heart rate or sweat.

They also listed tricks that help, like blowing bubbles, counting, or breathing slow.

The paper does not give new numbers. It simply says use more than one pain ruler and add CBT tricks.

No single tool wins; mixing tools gives the clearest picture.

Cramm et al. (2009) did the same kind of work, but with adults who cannot talk. They show one checklist, the NCAPC, is reliable when staff and parents use it. L et al. agree that checklists help, yet they push for kid-size sets that mix talk, watch, and body data.

Quigley et al. (2018) also wrote a no-numbers review, but on SAFMEDS flash-cards. Both papers end with “we need more proof,” showing story reviews often close with a call for real data.

Leaf et al. (2012) and Reni et al. (2022) go further. They counted PECS trials and found clear gains for preschoolers with autism. Their math fills the gap L et al. left open, turning “try distraction” into “teach picture exchange and move through all phases.”

Next time a child freaks out over a shot, do not trust just one pain score. Watch the face, ask the kid, and check heart rate. Then pick a CBT trick like bubbles or picture cards. If the child uses PECS, let them request “done” pictures during the poke. You turn a scary moment into a clear signal the child can control.
