Manouvrier Table - Height and Weight Estimation from Ulna
Height and body weight estimation from ulna length (Manouvrier table). Essential in resuscitation when patient cannot be measured.
assessmentemergency_medicineB
Clinical Purpose
Anthropometric estimation in uncooperative patients (trauma, coma, agitation) for weight-based drug dosing and mechanical ventilation
⚠️ Warnings and Limitations
Contraindications:
- •⚠️ NOT valid in bone deformities (ulna fractures, severe arthritis)
- •⚠️ NOT valid in bone diseases (severe osteoporosis with deformity)
- •⚠️ Caution in pediatric age (<18 years) - use pediatric formulas
- •⚠️ In ICU: consider edema/muscle wasting for weight
Limitations:
- •Formula based on Caucasian population (Manouvrier, 1893)
- •Inter-ethnic variability: ±5-7% for Asian/African populations
- •Weight estimated with average BMI: in obese/cachectic may vary ±30%
- •Does not replace direct measurement when possible
- •In emergency: preferable to visual estimation (error >40%)
Parameter Input
Fill in all required fields to proceed with the calculation
Distance olecranon → styloid process (arm flexed 90°)
Range: 15 - 35 cm
Different formulas by sex (Manouvrier coefficients)
Adult age for BMI correction (optional, default 40)
Range: 18 - 100 anni
Fields completed: 0 / 2
📚 Special Notes
- 📏 Measurement technique: arm bent 90°, measure from olecranon to ulnar styloid
- 🎯 Accuracy: ±3cm for height (95% CI)
- ⚖️ Weight: estimated with age-specific average BMI (±30% in obesity/cachexia)
- 🚑 ICU use: dosing life-saving drugs when scale not available
- 🫁 Ventilation: ideal body weight calculation for protective tidal volume
- ⚠️ Limitations: Caucasian population (±5-7% ethnic variability)
