The Holliday-Segard nomogram approximates daily fluid loss, and therefore the daily fluid requirements, as follows:
- 100 ml/kg for the 1st 10 kg of wt. He
- 50 ml/kg for the 2nd 10 kg of wt.
- 20 ml/kg for the remaining wt.
Even though it is correct to think about fluid requirements on a 24-hour basis, the delivery pumps used in hospitals are designed to be programmed for an hourly infusion rate. The 24-hour number is often divided into approximate hourly rates for convenience, leading to the "4-2-1" formula.
- 100 ml/kg/24-hours = 4 ml/kg/hr for the 1st 10 kg
- 50 ml/kg/24-hours = 2 ml/kg/hr for the 2nd 10 kg
- 20 ml/kg/24-hours = 1 ml/kg/hr for the remainder
So, for a 30 kg child, maintenance fluid rate would be:
- 40 ml/hr + 20 ml/hr + 10 ml/hr = 70 ml/hr
Perhitungan Tetesan INfus
Tetesan Makro 1cc = 15 tetes
Tetesan/Minit = Jumlah cairan (cc) / Lama infus (jam) x 4
Tetesan Makro 1cc = 20 tetes
Tetesan/Minit = Jumlah cairan (cc) / Lama infus (jam) x 3
Tetesan Mikro 1 cc = 60 tetes
Tetesan/Minit = JUmlah cairan (cc) / Lamanya infus (jam)
Hmm!! This blog is really cool, I’m so lucky that I have reached here and got this awesome information.
