Effect of Ice Chips on interdialytic weight gain in patients on hemodialysis in Mashhad hospitals in 2013

Excessive interdialytic weight gain (IDWG) in hemodialysis (HD) patients has serious effects. Therefore patients should follow a fluid-restriction diet. Non-adherence to fluid restriction can lead to excessive IDWG. The aim of this study was to determine the effect of ice chips on thirst, xerostomia and IDWG in HD patients.

This one- group pretest- posttest study included 49 HD patients and had three stages. In the first week (baseline stage) the patients received instructions for three sessions. In the second week (liquid stage) patients consumed fluid for one week and in the third week (ice chip stage) patients consumed fluid and ice intermittently for one week. Weights of the patients were measured before and after every dialysis session. Thirst and dry mouth were evaluated only before the dialysis session. Using SPSS version 16, data were analyzed by t-test and Wilcoxon tests.

The average IDWG (p=0.001) and xerostomia scores (p=0.041) in the two stages of fluid and ice chips were significantly different. Comparison of the thirst scores (p=0.127) between the two stages of fluids and ice chips showed no significant difference.

Consumption of ice chips led to reduction in IDWG which was indicative of less fluid consumption by the patients. This is one of the most important goals of care in HD patients, and can be used as an educational recommendation for them
