Parkland Replacement Fluids

`V = 4 * m * A`
`(m)"Weight Patient"`
`(A)"Percent of Body Burned"`

The Parkland Replacement Fluids calculator computes the amount of fluids required for the first 24 hours in a burn patient using the Parkland Formula and the patient's weight (mass) and percent of the body surface area burned.

INSTRUCTIONS:  Choose units and enter the following:

Replacement Fluids (V):  The calculator returns the volume of replacement fluids in liters (L). However, this can be automatically converted to other volume units (e.g. cups) via the pull-down menu.

Burn Surface Area

Wallace Rule of Nines/attachments/18825354-657b-11e7-9770-bc764e2038f2/513_Degree_of_burns.jpgRule of Fives (Obese Patients) /attachments/18825354-657b-11e7-9770-bc764e2038f2/Rule of Five.jpg   Percent of Burned BodyThe Wallace Rule of Nines can be used to approximate the percent of a patient that is burned.   It applies a percent of Body Surface Area, often a multiple of 9, for different body parts as follows:

  • (9%) Entire head
  • (9%) Complete left arm
  • (9%) Complete right arm
  • (9%) Entire chest
  • (9%) Entire abdomen
  • (18%) Complete back
  • (1%) Groin
  • (18%) Complete left leg
  • (18%) Complete right leg

The Rule of Fives can be used to approximate the percent of an obese patient that is burned.   It applies a percent of Body Surface Area, and differs from the Wallace Rule of Nines in that it applies a larger portion of the body surface area to the trunk and legs as follows:

  • (2%) Entire head
  • (5%) Complete left arm
  • (5%) Complete right arm
  • (50%) Trunk
  • (20%) Complete left leg
  • (20%) Complete right leg

Body Surface Area (BSA) is the measured or calculated surface area of a human body frequently used in physiology and medicine. For many clinical purposes BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Estimation of BSA is simpler than many measures of volume.

Body Surface Area (BSA) Calculators

Other BSA Applications

  • The BSA Compare function lets you enter a body surface area and choose a demographic (above) to compute the percent compared to the mean.
  • Wallace Rule of Nines:  This computes a percentage of the human body for burn victims based on percentages allocated to different body parts.
  • Rule of Fives: This computes a percentage of the human body for obese burn victims.
  • Parkland Replacement Fluid: This compute the volume of replacement fluids needed in the first 24 hours based on the patients weight (mass) and the percent of their body that has been burned.
  • BSA Percent: This computes a body surface area based on the total body surface area and a percent..
