What is the formula for the Holliday Segar maintenance fluid calculation?
What is the formula for the Holliday Segar maintenance fluid calculation?
The Holliday-Segar nomogram approximates daily fluid loss, and therefore the daily fluid requirements, as follows: 100 ml/kg for the 1st 10 kg of wt. 50 ml/kg for the 2nd 10 kg of wt. 20 ml/kg for the remaining wt.
What is the 421 rule?
In anesthetic practice, this formula has been further simplified, with the hourly requirement referred to as the “4-2-1 rule” (4 mL/kg/hr for the first 10 kg of weight, 2 mL/kg/hr for the next 10 kg, and 1 mL/kg/hr for each kilogram thereafter.
How do you calculate IVF per hour?
The formula to calculate how many hours will it take for the IV to complete before it runs out is: Time (hours) = Volume (mL) Drip Rate (mL/hour) . The volume of the fluid is 1 000 mL and the IV pump set at 62 mL/hour.
How do you calculate percentage of dehydration?
After clinical signs have been observed, the degree (%) of dehydration should be determined. This is calculated by dividing the difference between the pre-illness and illness weights by the pre-illness weight, then multiplying by 100 (Table 5). For example, a 10-kg patient who has lost 1 kg is 10% dehydrated.
How is TFI calculated?
Results
- For 0 – 10 kg = weight (kg) x 100 mL/kg/day.
- For 10-20 kg = 1000 mL + [weight (kg) x 50 ml/kg/day]
- For > 20 kg = 1500 mL + [weight (kg) x 20 ml/kg/day]
What is the 24 hour fluid requirement for a child weighing 32 kg?
Pediatric Fluid Management
| Weight | Minimum fluid intake per hour | Minimum fluid intake per shift |
|---|---|---|
| 6 kg | 24 cc/hour | 192 cc/shift |
| 7 kg | 28 cc/hour | 224 cc/shift |
| 8 kg | 32 cc/hour | 256 cc/shift |
| 9 kg | 36 cc/hour | 288 cc/shift |
How do you calculate IVF?
If you simply need to figure out the mL per hour to infuse, take the total volume in mL, divided by the total time in hours, to equal the mL per hour. For example, if you have 1,000 mL NS to infuse over 8 hours, take 1,000 divided by 8, to equal 125 mL/hr. To calculate the drops per minute, the drop factor is needed.
