Use of a menthol popsicle in managing postoperative thirst in patients undergoing radical prostatectomy: A randomized...

Background and aim: Thirst is a real bother that most patients feel in the immediate postoperative period when they still need to fast. Many approaches regarding symptomatic relief strategies have been described in the literature, but strategies with cold water and/or menthol are effective in quenching thirst, as they act on pre-absorptive mechanisms. This study aims to evaluate the effectiveness of using menthol popsicles in relieving postoperative thirst in patients undergoing radical prostatectomy. Material and methods: This is a randomized controlled clinical trial with a quantitative approach. In all, 44 patients were evaluated in the immediate postoperative period of radical prostatectomy, with the intensity and discomfort of thirst being evaluated initially and subsequently. The study consisted of two groups: (1) the placebo group, popsicles without the addition of menthol substrates and (2) the experimental group, popsicles with the addition of 0.05% minty substrates. Results: The results demonstrate that the sociodemographic and clinical characteristics were homogeneous at the α = 5% significance level, except the occupation variable. The test detected changes in the intensity and discomfort of thirst in relation to the pre- and post-intervention times for the primary outcome when the groups were analyzed separately and for the interaction of the group versus time, there was no statistical difference between the groups. Conclusion: It was possible to prove that both the menthol popsicle and the popsicle without the addition of menthol were effective in relieving postoperative thirst in patients undergoing radical prostatectomy, but there was no statistically significant difference when comparing the two groups.
