๐ paeds.online โ Pakistan's Pediatric Platform| Tool | Age Range | Description | Advantages / Limitations |
|---|---|---|---|
| FLACC (Face, Legs, Activity, Cry, Consolability) | 2 months - 7 years (also validated for cognitively impaired) | Behavioral scale (0-10). Each category 0-2. Total score 0-10. | Quick, reliable for post-op pain. Overrates pain in toddlers; underrates persistent pain. |
| FACES Pain Scale - Revised (FPS-R) | 3 years and older | Six faces from no pain (0) to worst pain (10). Child points to face. | Easy to use, good psychometrics. Not culturally universal (neutral vs smiling face). |
| Numeric Rating Scale (NRS) | 6-8 years and older | Integers 0 (no pain) to 10 (worst pain). Verbal or written. | Requires numerical understanding and ability to conceptualize pain intensity. |
| Visual Analog Scale (VAS) | 6-8 years and older | 10 cm line from 'no pain' to 'worst pain'. Child marks spot. | Good for research; requires motor and cognitive skills. |
| CRIES (Neonatal) | Neonates (0-6 months) | Crying, Requires O2, Increased VS, Expression, Sleeplessness. 0-2 each, total 0-10. | Validated for post-op pain in neonates. Vital signs may be influenced by other factors. |
| N-PASS (Neonatal Pain, Agitation, Sedation Scale) | Preterm/term neonates | Combined behavioral and physiologic parameters. Scores -10 to +10. | Assesses both pain and sedation. Useful in ventilated neonates. |
| CHEOPS (Children's Hospital of Eastern Ontario Pain Scale) | 1-7 years | Behavioral scale (cry, facial, verbal, torso, touch, legs). 4-13 points. | Valid for acute procedural pain. Time-consuming. |
| Category | 0 points | 1 point | 2 points |
|---|---|---|---|
| Face | No particular expression or smile | Occasional grimace or frown; withdrawn or disinterested (appears sad or worried) | Frequent to constant quivering chin, clenched jaw, or distressed expression |
| Legs | Normal position or relaxed | Uneasy, restless, tense (occasional tremors) | Kicking, or legs drawn up, or marked increase in spasticity/tremors |
| Activity | Lying quietly, normal position, moves easily | Squirming, shifting back and forth, tense (mildly agitated, head back and forth, aggression; shallow respirations, intermittent sighs) | Arched, rigid, or jerking movements; severe agitation, head banging, shivering |
| Cry | No cry (awake or asleep) | Moans or whimpers; occasional complaint (occasional verbal outburst or grunt) | Crying steadily, screams or sobs, frequent complaints |
| Consolability | Content, relaxed | Reassured by occasional touching, hugging, or talking; distractible | Difficult to console or comfort |
