简要总结
The objective of this study was to compare the effectiveness of menthol chewing gum compared to maintained fasting (usual care) in reducing the intensity of the surgical patient's thirst during the preoperative period. The hypothesis of the study was that the use of menthol chewing gum in surgical patients in the preoperative period would be more effective than the maintenance of fasting with regard to the decrease in thirst and its discomforts.
详细描述
There is evidence that chewing gum is effective in relieving thirst in the surgical patient in the preoperative period as it stimulates the salivary glands by means of mechano and chemoreceptors, increasing the salivary pH and flow, lubricating the oral cavity, acting in this way on peripheral thirst, which is triggered by dehydration of the oral mucosa. Furthermore, menthol gum stimulates the cold receptors, known as TRPM8, which are responsible for deactivating centers of thirst. Thus, the risk of bronchoaspiration due to gastric fullness is avoided and the discomfort of a dry mouth is reduced.Preliminary evidence indicates that the chewing gum strategy assists in the relief of a dry mouth and thirst in patients undergoing dialysis and head and neck radiotherapy. However, there is no scientific evidence of controlled studies with results that can be generalized regarding the use of chewing gum to reduce thirst and its discomforts in surgical patients in the preoperative period when they remain in a fasted state.

研究组 & 干预措施
menthol chewing gum
Allocation concealment was performed through the use of individual opaque envelopes numbered externally in sequence, containing the randomly defined group information.This step was performed by a researcher who did not participate in the data collection. The intensity of the initial thirst was measured by means of the Verbal Numerical Scale (VNS), which ranged from 0 (no thirst) to 10 (very intense thirst) and the discomfort of the initial thirst was measured through the Perioperative Thirst Discomfort Scale (PTDS), which is composed of 7 attributes and ranges from 0 to 14. After using the intervention (menthol chewing gum) for 10 minutes, chewing at a natural rhythm and swallowing the saliva produced, the intensity and final discomfort were measured using the same scales.

Usual care (maintenance of fasting)

After maintaining the usual care, that is, reaffirming the need for fasting for 10 minutes, the intensity and final discomfort were measured using the same scales.

结局指标
主要结局
intensity of thirst
时间窗: 10 minutes
Alteration in the evaluation of the final intensity of thirst in relation to the evaluation of the initial intensity of thirst \[10 minutes\]. For evaluation of the intensity of thirst, a Verbal Numeral Scale (VNS) was used, with a range from 0 (no thirst) to 10 (very intense thirst), as reported by the patients when questioned.
次要结局
- discomfort of thirst(10 minutes)
