Strategies for thirst management in postoperative adult patients: a scoping review.

OBJECTIVES: to map the strategies for managing thirst in postoperative adult patients. METHODS: scoping review was conducted in October 2021 in 19 data sources: 14 databases and 5 platforms to search in the grey literature. It was prepared according to the recommendations of the Joanna Briggs Institute and the checklist of the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. Nine selected articles were part of the final sample. RESULTS: there is evidence of strategies to manage postoperative thirst using interventions such as water, ice, mentholated measures, carbohydrate and protein enriched fluid, oral hydrator, flavored gargling, cold gargling, wet gauze, 0.75% citric acid spray, and cold water. FINAL CONSIDERATIONS: the strategies observed may be reduced to cold and menthol use, salivary stimulants, and early introduction of fluids. The outcomes were positive in all the studies reviewed.

Post-Exercise Voluntary Drinking Cessation Is Associated with the Normalization of Plasma Osmolality and Thirst Perception, but Not of Urine Indicators or Net Fluid Balance.

Post-exercise rehydration has been widely studied, with particular emphasis on retention of ingested fluid; comparatively little research has been conducted on why we drink more or less. To identify physiological values corresponding to voluntary drinking cessation (VDC), nine males exercised intermittently at 70−80% HRmax in the heat (WBGT = 28.1 ± 0.7 °C) to achieve a dehydration of approximately 4.0% body mass (BM). After exercise, participants were instructed to drink water as long and as much as they needed. Urine color (Ucolor), specific gravity (USG), osmolality (Uosm), plasma osmolality (Posm), fullness, BM, and thirst perception (TP) were measured pre- and post-exercise and at VDC. Each variable was compared for the three points in time with a one-way ANOVA. Participants reached dehydration of −3.6 ± 0.3% BM. Pre-exercise USG (1.022 ± 0.004) was lower than at VDC (1.029 ± 0.004, p = 0.022), Uosm did not change over time (p = 0.217), and Ucolor was lower pre-exercise (3.4 ± 0.7) vs. post-exercise (5.5 ± 1.23, p = 0.0008) and vs. VDC (6.3 ± 1.1, p < 0.0001). Posm showed a difference between pre-exercise (289.5 ± 2.3) and post-exercise (297.8 ± 3.9, p = 0.0006) and between post-exercise and VDC (287.3 ± 5.4, p < 0.0001). TP post-exercise (96.4 ± 4.34) was significantly higher than pre-exercise (36.2 ± 19.1) and VDC (25.0 ± 18.2, p < 0.0001). At VDC, participants had recovered 58.7 ± 12.1% of BM loss. At the point of voluntary drinking cessation, Posm and thirst perception had returned to their pre-exercise values, while rehydration relative to initial BM was still incomplete.

Effects of carbohydrate use on preoperative thirst: a randomized clinical trial.

OBJECTIVES: to evaluate the effectiveness of carbohydrate popsicles, carbohydrate solution, and usual care (fasting) on the intensity and discomfort of preoperative thirst. METHODS: a randomized clinical trial with 60 preoperative patients aged between 18 and 60 years, randomized into three groups: control (fasting), carbohydrate solution (100 ml), and carbohydrate popsicle (100 ml). The outcomes were thirst intensity and discomfort. RESULTS: there was a difference between groups for final thirst intensity (p = 0.01) and final thirst discomfort (p = 0.001). The effect size for both the Solution Group and the Popsicle Group was robust: 0.99 and 1.14, respectively. CONCLUSIONS: the groups that received the carbohydrate fasting abbreviation showed a reduction in thirst discomfort compared to the control group. The carbohydrate popsicle proved more effective in reducing the intensity of thirst. NCT: 3.209.283.

Comparison of dipsogenic responses of adult rat offspring as a function of different perinatal programming models.

The perinatal environment interacts with the genotype of the developing organism resulting in a unique phenotype through a developmental or perinatal programming phenomenon. However, it remains unclear how this phenomenon differentially affects particular targets expressing specific drinking responses depending on the perinatal conditions. The main goal of the present study was to compare the dipsogenic responses induced by different thirst models as a function of two perinatal manipulation models, defined by the maternal free access to hypertonic sodium solution and a partial aortic ligation (PAL-W/Na) or a sham-ligation (Sham-W/Na). The programmed adult offspring of both perinatal manipulated models responded similarly when was challenged by overnight water dehydration or after a sodium depletion showing a reduced water intake in comparison to the non-programmed animals. However, when animals were evaluated after a body sodium overload, only adult Sham-W/Na offspring showed drinking differences compared to PAL and control offspring. By analyzing the central neurobiological substrates involved, a significant increase in the number of Fos + cells was found after sodium depletion in the subfornical organ of both programmed groups and an increase in the number of Fos + cells in the dorsal raphe nucleus was only observed in adult depleted PAL-W/Na. Our results suggest that perinatal programming is a phenomenon that differentially affects particular targets which induce specific dipsogenic responses depending on matching between perinatal programming conditions and the osmotic challenge in the latter environment. Probably, each programmed-drinking phenotype has a particular set point to elicit specific repertoires of mechanisms to reestablish fluid balance.

The gut-brain axis and sodium appetite: Can inflammation-related signaling influence the control of sodium intake?

Sodium is the main cation present in the extracellular fluid. Sodium and water content in the body are responsible for volume and osmotic homeostasis through mechanisms involving sodium and water excretion and intake. When body sodium content decreases below the homeostatic threshold, a condition termed sodium deficiency, highly motivated sodium seeking, and intake occurs. This is termed sodium appetite. Classically, sodium and water intakes are controlled by a number of neuroendocrine mechanisms that include signaling molecules from the renin-angiotensin-aldosterone system acting in the central nervous system (CNS). However, recent findings have shown that sodium and water intakes can also be influenced by inflammatory agents and mediators acting in the CNS. For instance, central infusion of IL-1ß or TNF-α can directly affect sodium and water consumption in animal models. Some dietary conditions, such as high salt intake, have been shown to change the intestinal microbiome composition, stimulating the immune branch of the gut-brain axis through the production of inflammatory cytokines, such as IL-17, which can stimulate the brain immune system. In this review, we address the latest findings supporting the hypothesis that immune signaling in the brain could produce a reduction in thirst and sodium appetite and, therefore, contribute to sodium intake control.

Abstract Objective To identify the prevalence and thirst intensity in children in the immediate postoperative period and its associated factors. Methods This is a cross-sectional and analytical study. The sample consisted of 78 children aged four to twelve years in the post-anesthesia care unit in the immediate postoperative period. Thirst presence, as well as its attributes and signs, were identified by questioning by the researcher and/or self-report of children and their caregivers. Thirst intensity was measured using the face scale. The outcome variables were thirst presence and intensity. Prevalence ratio was calculated by Poisson regression, with robust variance. Results The prevalence of thirst was 88.5%, with 39.7% reporting thirst in the postoperative period and 48.7% since the preoperative period. As for the intensity, 20.5% reported strong thirst and 37.2% intense thirst. Additionally, more than half of the children (59%) reported it spontaneously. The factors associated with greater thirst intensity were: female sex (PR=1.27); spontaneous complaint (PR=1.29); reporting feeling of dry mouth (PR=1.93) and thick saliva (PR=1.43); age was inversely associated with thirst intensity, i.e., the younger the age, the greater the thirst intensity (beta= -0.053; p=0.01). Conclusion Thirst in surgical children has a high prevalence and intensity. Children are able to identify the signs related to thirst and spontaneously reports it. Sex, spontaneous complaints, age, dry mouth and thick saliva were associated with intensity. These results signal the need for intentional interventions to reduce child thirst in clinical practice.

Awareness of Fluid Losses Does Not Impact Thirst during Exercise in the Heat: A Double-Blind, Cross-Over Study.

BACKGROUND: Thirst has been used as an indicator of dehydration; however, as a perception, we hypothesized that it could be affected by received information related to fluid losses. The purpose of this study was to identify whether awareness of water loss can impact thirst perception during exercise in the heat. METHODS: Eleven males participated in two sessions in random order, receiving true or false information about their fluid losses every 30 min. Thirst perception (TP), actual dehydration, stomach fullness, and heat perception were measured every 30 min during intermittent exercise until dehydrated by ~4% body mass (BM). Post exercise, they ingested water ad libitum for 30 min. RESULTS: Pre-exercise BM, TP, and hydration status were not different between sessions (p > 0.05). As dehydration progressed during exercise, TP increased significantly (p = 0.001), but it was the same for both sessions (p = 0.447). Post-exercise water ingestion was almost identical (p = 0.949) in the two sessions. CONCLUSION: In this study, thirst was a good indicator of fluid needs during exercise in the heat when no fluid was ingested, regardless of receiving true or false water loss information.

Effect of preoperative oral liquid carbohydrate intake on blood glucose, fasting-thirst, and fatigue levels: a randomized controlled study.

BACKGROUND: This study aimed to analyze the effects of preoperative oral intake of liquid carbohydrate on postoperative blood glucose, fasting-thirst, and fatigue levels in patients undergoing arthroscopic surgery. METHODS: This randomized controlled clinical trial enrolled 82 patients, who were scheduled to undergo arthroscopic surgery, and divided them into two groups: (1) those who consumed a carbohydrate-rich drink, and (2) those not consuming anything after midnight. Pre- and postoperative fasting-thirst (visual analog scale) and blood glucose levels were measured. Likewise, the Brief Fatigue Inventory was applied to patients 24 hours after surgery. RESULTS: The mean blood glucose levels in the first postoperative hour were 90.90 ± 13.56 mg.dL-1 and 107.00 ± 15.84 mg.dL-1 in the intervention group and control group, respectively (p < 0.001). The postoperative mean thirst scores were 4.70 ± 1.59 and 6.36 ± 2.07 in the intervention group and control group, respectively (p < 0.001). Their corresponding postoperative mean fasting scores were 5.54 ± 1.76 and 5.86 ± 1.79 (p > 0.05) and the mean fatigue levels in the 24th postoperative hour were 4.80 ± 2.13 and 5.48 ± 1.46, respectively (p > 0.05). CONCLUSIONS: Oral intake of liquid carbohydrate before spinal anesthesia was found to have positive effects on patients' postoperative blood glucose and thirst levels.

Development and validation of a new nursing diagnosis: Perioperative thirst.

PURPOSE: To develop and validate the content of the nursing diagnosis proposal for perioperative thirst. METHODS: A content analysis by 34 judges. An online Delphi panel was used in one round, evaluating criteria of relevance, clarity and precision. Wilcoxon's one-tailed test was used and the content validity index to maintain the item was set to 0.80. FINDINGS: The content validity index in relation to the evaluated items reached levels between 0.87-1.00. The final components of the diagnosis proposal included the following items as defining characteristics: dry mouth, dry throat, dry lips, thick saliva, thick tongue, constant swallowing of saliva, desire to drink water, bad taste in the mouth, and caregiver's report. Related factors are as follows: pre- and postoperative fasting, oral breathing, dehydration, hypovolemia, insensitive loss of hydration by breathing, dry mouth, habit of drinking water, high room temperature. Associated conditions: intubation, use of muscarinic and nicotinic anticholinergics and water restriction. CONCLUSIONS: All components of the nursing diagnosis were validated in relation to relevance, clarity, and accuracy, demonstrating high levels of agreement between experts. Qualitative observations were found to be fundamental for both combining and excluding some items. IMPLICATIONS FOR NURSING PRACTICE: Improvement of refinement and clarity levels of this nursing diagnosis proposal aiding its inclusion in the NANDA International taxonomy and thus enabling greater understanding of the phenomenon of thirst in surgical patients. This study helps to explain and facilitate the identification of defining characteristics, related factors, and associated conditions for nurses, nursing students, and researchers on this subject.

Concept analysis of Perioperative Thirst for the development of a new nursing diagnosis.

OBJECTIVES: to analyze the perioperative thirst concept for the development of a new diagnostic structure according to NANDA International. METHODS: a concept analysis study based on the framework proposed by Walker and Avant, instrumentalized through an integrative literature review based on SCOPUS, CINAHL, PUBMED, LILACS, and WOS. The elaboration of the diagnostic structure followed NANDA International guidelines. RESULTS: 41 studies were analyzed revealing that perioperative thirst is prevalent and intense, having visceral and behavioral attributes as the core of the concept. Antecedents indicate that surgical patients are vulnerable to thirst; and consequents 16 signs and symptoms were organized and model cases were developed. A diagnostic structure has been developed for perioperative thirst. FINAL CONSIDERATIONS: concept analysis allowed language standardization that describes thirsty patients, helping the identification, planning of actions and communication of perioperative nursing care.

Effects of the ice popsicle on vasopressin, osmolality, thirst intensity, and thirst discomfort.

OBJECTIVE: To analyze the effects of the ice popsicle on vasopressin, osmolality, thirst intensity, and thirst discomfort. METHOD: This is a quasi-experimental, pre- and post-test study conducted in a laboratory. The sample consisted of nine healthy male volunteers, who received 2% hypertonic saline solution. RESULTS: Popsicle intake did not result in a statistically significant reduction in vasopressin levels (F=0.876 and p=0.428). However, there was a reduction in the hormonal physiological profile of vasopressin from 7.1 pg/ml to 5.8 pg/ml after the first two interventions. Osmolality concentration changed from 270.65 to 286.51 mOsm/kg, with no statistical difference (F=2.207; p=0.09). Ice popsicles significantly reduced thirst intensity (F=10.00; p=0.001) and thirst discomfort (F=10.528; p <0.001). CONCLUSION: There was a reduction in thirst intensity and discomfort after the use of the 20 ml ice popsicle. There was no statistical difference for vasopressin and osmolality. However, there was a reduction in the hormonal physiological profile of vasopressin during 30 minutes of intervention.
