Parkland formula for burn fluid resuscitation is described as?

Parkland formula for burn fluid resuscitation is described as?

• A. 4 x % x wt in kg; divide by 2
• B. 4 x % x wt in kg; then divide by 3 bc they should receive half the fluid in the first 8 hours
• C. 2 x % x wt in kg; divide by 3
• D. 4 x % x wt in kg; divide by 4

Answer: (B)

Parkland formula establishes how much fluid a burn patient needs over the first 24 hours and how to time that fluid. It uses lactated Ringer’s solution at 4 mL per kilogram of body weight for each percent of TBSA burned. The key scheduling rule is that half of that total volume is given in the first 8 hours after the burn, and the remaining half is given over the next 16 hours. This creates a rapid initial resuscitation window followed by a slower, sustained return to balance. For example, a 70 kg patient with 50% burns would have a total of 4 × 70 × 50 = 14,000 mL over 24 hours. In the first 8 hours, 7,000 mL are given (roughly 875 mL/hour), and the remaining 7,000 mL are given over the next 16 hours (about 437.5 mL/hour). If the injury is older than 8 hours, you adjust the remaining fluid delivery to finish within the remaining time window. This approach emphasizes giving half of the calculated volume early (in the first 8 hours) and the other half afterward, rather than distributing the fluid in thirds or using the wrong division.
