Rule of Nines Math Activity
Please indicate the total burn surface area (TBSA) of the burns described below. Then calculate the fluid
resuscitation needed in the timeline indicated. Please use the Parkland formula: 4 mlX KG X TBSA.
Round whole number
1. An 18 yr old male weighing 82 kg burns his back (18), the back of his left leg(9,) and his entire
right arm (9)in a house fire. =36 in TBSA
a. TBSA – 36 Rate for 1st 8 hrs – 738ml/1hr
b. 24 hours – 11808 24hrs Rate for last 16 hrs – 369/1hr
c. 8 hours – =5904/2=738
2. A 26 yr old female was burned while starting the grill while using gasoline to “speed things up.”
She burned her face (4.5), her bilateral anterior arms(4.5)x2 , and her chest (18). She weighs 176
lbs/2.2kg.=80kg 4ml x 80kg x31.5%=
a. TBSA – 31.5%
b. 24 hours – 10,080 ml Rate for 1st 8 hrs – 4,320/= (540ml/1hr)
c. 8 hours – /2 =4,320 /8 hrs Rate for last 16 hrs – 4320/16hrs= (270ml/1hr)
3. A 25 yr old male weighing 104 kg is involved in a car accident. He burns his chest (18)and
perineal area (1%). =19 % tbsa 4ml x 104kg x 19%= 7, hr
a. TBSA – 19%
b. 24 hours – 7, hr Rate for 1st 8 hrs – 3,952/8hrs=494ml/1hr
c. 8 hours –/2= 3,952 total volume =8 hrs Rate for last 16 hrs – 3,952/16hrs=247ml/1hr
4. A 46 yr old male is burned by a gasoline explosion while starting his lawn mower. He burns the
anterior portion of both legs(9)+(9+)=18, his perineal area(1), his chest (18), and the anterior
portion of both arms(4.5)+(4.5)=9. He weighs 264 lbs./2.2kg=120kg 18+1+18+9=46%tbsa
4ml x 120kg x 46 tbsa =22,080 ml /24 hrs
a. TBSA – 46%
b. 24 hours – 22,080 ml/24hrs Rate for 1st 8 hrs – 11,040ml/8hrs=1,380 ml/1 hr
c. 8 hours –/2=11,040ml/8hrs Rate for last 16 hrs – 11,040ml/16hrs=690ml/1hr
5. A 52 yr old female burns half her chest (18)=, most of her back (18), and most of her left leg
(9)while retrieving her cat from a house fire. She weighs 143 lbs./2.2kg=65 kg
18+18+18=54% tbsa 4ml x 65kg x 36 = 9,360 ml/24 hrs
a. TBSA – 36%
b. 24 hours – 9,360 ml /24 hrs Rate for 1st 8 hrs – 4,680ml/8hrs= 545ml/ 1 hr 77.5
c. 8 hours – /2= 4,680ml/ 8hrs Rate for last 16 hrs – 4,680 ml/16 hrs=292.5ml/1hr(293ml/1hr)? 438.8
6. A 68 yr old man lights a cigarette while filling up his tank at Valero. He burn his face (4.5), his
chest (18), and his bilateral arms4.5x2 (9)+4.5x2(9). Running away, he managed to stop drop and
roll which then spread the fire to his back (18). He weight 242 lbs/2.2kg.=110kg
4.5+18+9+9+18= 58.5 tbsa
