HollidaySegarmetoden

HollidaySegarmetoden, also known as the Holliday-Segar formula, is a method used to calculate the initial daily fluid maintenance requirement for patients undergoing surgery or intensive care. It was developed by Robert Holliday and John Segar in the 1960s. The formula takes into account the patient's weight and the presence of burns or third-degree burns to determine the appropriate fluid replacement rate.

The Holliday-Segar formula is as follows:

For patients without burns:

4 mL/kg/hour for the first 10 kg of body weight

3 mL/kg/hour for the next 10 kg of body weight

2 mL/kg/hour for the remaining body weight

For patients with burns:

4 mL/kg/hour for the first 10 kg of body weight

2 mL/kg/hour for the next 10 kg of body weight

1 mL/kg/hour for the remaining body weight

The formula is designed to provide adequate hydration while minimizing the risk of fluid overload. It is important to note that the Holliday-Segar formula is just one of many methods used to calculate fluid maintenance requirements, and the appropriate formula may vary depending on the patient's specific circumstances.

The Holliday-Segar formula has been widely used in clinical practice for many years, but it has also been criticized for its simplicity and lack of consideration for factors such as age, sex, and underlying medical conditions. As a result, more complex formulas have been developed in recent years to better tailor fluid replacement to individual patients. However, the Holliday-Segar formula remains a useful tool for clinicians in many settings.
