Target weight procedure: preventing water intoxication.

1. Prevention of water intoxication depends on early intervention for polydipsic patients who seem to be retaining fluid. The Target Weight Procedure is designed to detect early signs of fluid retention by means of weight gain and low sodium levels. 2. The use of this protocol, in addition to successfully decreasing the number of acute water intoxication episodes, has also led to increased awareness of the meaning of patient behavior, an increased sense of control of patients with water intoxication over their behavior, and an increased feeling of competence among the staff. 3. The success of the protocol seems to be based on its purpose of identifying patients at risk and those with an impending episode, as well as secondary advantages, for example, giving the patients the option to alter their behavior to be removed from the protocol.
