The fluid restriction program included (a) General small-group discussion sessions, (b) individualized consultations, and (c) follow-up sessions.

The intervention bundle, the fluid restriction program, and auricular acupressure were received at four appointments: Shenmen, Kidney Concha, Point Zero, and Upper Tragus.

In order to design the fluid restriction program content (booklet). The fluid restriction program included (a) General small-group discussion sessions, (b) individualized consultations, and (c) follow-up sessions. In the group discussion sessions, children in both the study and control groups were divided into subgroups (6 participants per each). In the group discussion sessions, children in both the study and control groups were divided into subgroups. The sessions were conducted in the meeting room of the Hemodialysis unit lasts for 45 minutes. In the Individualized Consultations, children then were provided tailored, age-appropriate education. The researchers also arranged for regular follow-up for one months.

This tool used to evaluate the salivary flow assessment. It consisted of 8 validated items measuring two main dimensions of salivary flow. The first dimension assessing the impaired oral functions due to the sensation of dry mouth as indicated by having difficulty in swallowing or speaking. While the second dimension evaluating the dryness of oral mucosa (lips, mouth, tongue, or throat). Additionally, children were asked two global questions regarding salivary quantity and thirsty level. In each item, children's responses were rated on a 100-mm horizontal numeric scale ranged from No (0) to very dry (100).

This scale consisted of 24 items to evaluate the knowledge, behavior and attitude toward fluid restriction among patients undergoing hemodialysis. These items measure patients' compliance with fluid control.
