1. LA CALCULATION
1.8 ml x 20mg/ml = 36 mg
2% of lidnocaine :20 mg/ml
Dalamcatridge,ada 1.8 ml solutionubat.Soberapaberat lidnocaine?Ada36 mg lidnocaine
2% lignocaine with epinephrine:

2.  1 kg pesakitada7 mglignocaine
 So max ubat bolehbagikatany weight= 500 mg (lebih500 mg bolehtoxicity)
 Contohberat100 kg, kira15 catridge and lebih500 mg. Hence tak lehbagi lebih500 mg.
70 kg (standardweightinref forLA calculation) =154 lb
2% lignocaine withoutepinephrine
- Dalamsatu catrige,ada 1.8 ml solution,berapaberatlignocaine?Dalam1.8ml ada bendalain
eg NA.
- 1.8 ml/catridge x 2%(20mg/ml) = 36 mg/catridge → Ada 36 mg lignocaine dalam1.8ml sol
- Utk 70 kgpt : 4.4 mg/kg x 70 kg= 308 mg
2% lignocaine withepinephrine tuada1.8mg/cc and 2.2 mg/cc. Infac, ada 2.2mg/cc.
Eg :
2% mepivacine
2.2 x 2% (20mg/ml) = 44 mg/cc.
44 mg/cc x 70 kg = 462 mg

3. - Dah guna 2 and½ cc
- I cc = 2.2 ml
- ½ cc = 2.2 ml /2 = 1.1
- 2 and ½ cc = 55 ml
- So berapamepivacine?
- I cc = 2% mepi = 20mg/ml
- 5.5 ml x 20mg/ml = 110 mg of 2% mepi
2% mepi in2.2 ml in 70 kg pt.Berapa cc nakbagi?
-2.2 ml x 20 mg/ml =44 mg/cc
- Mx dose – 6.6 mg/kg
-70 kg x 6.6mg/kg = 462 mg
Berapac??
462 mg ÷ 44 mg/cc = 10.5 cc = 10 cc
