Answer 1

Enteral Tube feeding calculation:

Step 1:

Convert patient's weight into kg.

Patient weight = 112lbs.

Patient weight in kg = 112 / 2.2 = 50.90kg.

Step 2:

Convert patient's height in inches.

Patient's height = 5.8 or 69.6inches.

Step 3:

Calculate the amount of calories required daily

By using Harris-Benedict formula

BMR for women = 655 + (4.35 X wt in Kg) + (4.7 X height in inches) - (4.7 X age in years)

= 655 + (4.35 X 50.90) + (4.7 X 69.6) - (4.7 X 30)

= 655 + 221.415 + 327.12 - 141

= 1203.535 - 141

=1062.535

BMR = 1063 (rounded off)

Step 4:

Calculation of total calories by multiplying BMR with activity.

For sedentary activity, BMR X 1.2

Total amount of daily calories = 1063 X 1.2

= 1275.6 kCal /day.

Step 5:

Calculate the rate of tube feeding

The recommended is Nutren 1.5Kcal/ mL

So, 1276 / 1.5 = 850.6 mL

The patients should be tube fed of 850mL per day

Rate of tube feeding per hr = 850 / 24 = 35.4mL

The patient required 35mL of tube fed per hour.

Step 6:

Calculation of water requirements

Multiply pt weight by 35mL/kg.

Water requirement = 50.90 X 35 = 1781.5 mL

Recommendations:

• Nutren 1.5mL should be fed at a rate of 35mL /hr.
• Elevate the bed at 35 - 45 degrees while tube feed.
• Initiated with 10mL/hr and followed by 10 - 20mL/hr.
• 297mL of water should be flushed every 4 hours.
• normal Albumin level should be maintained.
