Trial Summary
What is the purpose of this trial?To determine the half time of the emptying of the stomach of women in early labor with and without epidural pain relief when drinking either water or a carbohydrate-based sports drink.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it excludes those who have received narcotics within 12 hours or are receiving magnesium sulfate.
What data supports the effectiveness of the treatment Sports Drink vs Water for Pregnant Women in Labor?
Research shows that drinks containing carbohydrates and electrolytes, like sports drinks, can help maintain hydration and physical performance during exercise, which may suggest they could be beneficial for hydration during labor as well.
12345Is it safe for humans to consume sports drinks?
Sports drinks, which are often used to maintain hydration and improve performance, are generally considered safe for human consumption. However, they can add extra calories to the diet, which may not be necessary for typical physical activities, especially in adolescents.
13678How does drinking sports drinks during labor differ from other treatments for hydration?
Drinking sports drinks during labor is unique because it provides carbohydrates, which can improve muscle performance and reduce fatigue, unlike plain water that may lead to water intoxication if consumed excessively. This approach is inspired by sports medicine, where carbohydrate intake is known to enhance physical performance.

Comparison of coconut water and a carbohydrate-electrolyte sport drink on measures of hydration and physical performance in exercise-trained men. [2021]Sport drinks are ubiquitous within the recreational and competitive fitness and sporting world. Most are manufactured and artificially flavored carbohydrate-electrolyte beverages. Recently, attention has been given to coconut water, a natural alternative to manufactured sport drinks, with initial evidence indicating efficacy with regard to maintaining hydration. We compared coconut water and a carbohydrate-electrolyte sport drink on measures of hydration and physical performance in exercise-trained men.
[Dehydration and rehydration of the human body. Physiopathologic and clinical considerations]. [2006]Dehydration is a frequent and important problem either occupational or athletic. Equally important is the research for a correct rehydration. The most capable beverages for the rehydration are composed by water, carbohydrates (glucose and its polymers), and electrolytes, because the absorptions of water, glucose and sodium are correlated. Moreover these solutions if properly dosed and balanced do not slacken the gastric emptying and the fluid absorption, they replace part of the exhausted carbohydrates and guarantee a good plasma electrolyte balance. To these benefits can be added the organic "stress" reduction and the physical endurance enhancement.
Palatability and voluntary intake of sports beverages, diluted orange juice, and water during exercise. [2019]Palatability and voluntary intake of 4 beverages commonly available to athletes were compared in a laboratory exercise protocol designed to mimic aerobic training or competitive conditions in which limited time is available for drinking. Diluted orange juice (DOJ), homemade 6% carbohydrate-electrolyte sports beverage (HCE), commercially available 6% carbohydrate-electrolyte sports beverage (CCE), and water (W) were tested. Fifty adult triathletes and runners (34 males, 16 females) exercised for 75 min at 80-85% of age-predicted heart rate, during which time they were given brief access (60 s) to one of the beverages after 30 min and 60 min of exercise. Results indicated that for overall palatability, CCE > W, HCE, DOJ; W > DOJ, and for amount of beverage consumed, CCE > W, HCE, DOJ; HCE > W, DOJ. The palatability of these beverages varied substantially, as did their voluntary intakes during exercise.

Anaerobic performance when rehydrating with water or commercially available sports drinks during prolonged exercise in the heat. [2016]The effects that rehydrating drinks ingested during exercise may have on anaerobic exercise performance are unclear. This study aimed to determine which of four commercial rehydrating drinks better maintains leg power and force during prolonged cycling in the heat. Seven endurance-trained and heat-acclimatized cyclists pedaled for 120 min at 63% maximum oxygen consumption in a hot, dry environment (36 degrees C; 29% humidity, 1.9 m.s-1 airflow). In five randomized trials, during exercise, subjects drank 2.4 +/- 0.1 L of (i) mineral water (WAT; San Benedetto), (ii) 6% carbohydrate-electrolyte solution (Gatorade lemon), (iii) 8% carbohydrate-electrolyte solution (Powerade Citrus Charge), (iv) 8% carbohydrate-electrolyte solution with lower sodium concentration than other sports drinks (Aquarius orange), or (v) did not ingest any fluid (DEH). Fluid balance, rectal temperature (Trec), maximal cycling power (Pmax), and leg maximal voluntary isometric contraction (MVC) were measured. During DEH, subjects lost 3.7 +/- 0.2% of initial body mass, whereas subjects lost only 0.8% +/- 0.1% in the other trials (p
Approaches to Reduce Sports Drink Consumption Among Adolescents. [2020]Sports drinks originally developed to improve performance and prevent or treat dehydration, heat stroke, and muscle cramps in elite athletes are consumed regularly by nearly 60% of the adolescent population. Sports drinks are often perceived as healthy, and marketing campaigns fail to delineate the types and amount of activity that warrant appropriate use. Current trends in adolescent consumption of sports drinks will be reviewed and approaches to reduce consumption, including counseling on the appropriate use of sports drinks, will be discussed.
Effects of isomaltulose ingestion on postexercise hydration state and heat loss responses in young men. [2020]What is the central question of this study? What are the effects of isomaltulose, an ingredient in carbohydrate-electrolyte beverages to maintain glycaemia and attenuate the risk of dehydration during exercise heat stress, on postexercise rehydration and physiological heat loss responses? What is the main finding and its importance? Consumption of a 6.5% isomaltulose-electrolyte beverage following exercise heat stress restored hydration following a 2 h recovery as compared to a 2% solution or water only. While the 6.5% isomaltulose-electrolytes increased plasma volume and plasma osmolality, which are known to modulate postexercise heat loss, sweating and cutaneous vascular responses did not differ between conditions. Consequently, ingestion beverages containing 6.5% isomaltulose-electrolytes enhanced postexercise rehydration without affecting heat loss responses.
Adolescent Consumption of Sports Drinks. [2021]Sports drinks are aggressively marketed to teenagers to replenish fluids and/or electrolytes. According to the American Academy of Pediatrics, typical adolescent physical activity does not require sports drink rehydration. Given US obesity rates and that sugar-sweetened sports drinks add superfluous calories to the diet, it is important to assess adolescent sports drink consumption and changes over time.
An evaluation of isotonic "sport drinks" during labor. [2022]We compared the metabolic effects of allowing women isotonic "sport drinks" rather than water to drink during labor. The effect of these drinks on gastric residual volume was also evaluated. Sixty women in early labor (cervical dilation
Does oral carbohydrate supplementation improve labour outcome? A systematic review and individual patient data meta-analysis. [2018]Labour is a period of significant physical activity. The importance of carbohydrate intake to improve outcome has been recognised in sports medicine and general surgery.
Effect of Oral Carbohydrate Intake During Labor on the Rate of Instrumental Vaginal Delivery: A Multicenter, Randomized Controlled Trial. [2020]Carbohydrate intake during physical exercise improves muscle performance and decreases fatigue. We hypothesized that carbohydrate intake during labor, which is a period of significant physical activity, can decrease the instrumental vaginal delivery rate.
The Amount of Fluid Intake among Pregnant Women in China Increases with Pregnancy Progression: A Prospective Cohort Study. [2023]Fluid intake and hydration status during pregnancy may have influences on maternal and infant health. However, few studies have recorded and analyzed total fluid intake (TFI) levels during the whole pregnancy. This study mainly aimed to investigate the TFI levels of pregnant women in three trimesters, and further to assess their hydration status. The relationships of TFI and hydration status were also analyzed. A convenience sampling method was used to recruit pregnant women from the Haikou Maternity and Child Health Hospital in China in this prospective cohort study. A 7-day 24 h fluid intake questionnaire was used for recording the fluid intake of the participants in their three trimesters. Fasting blood samples and first morning urine samples were also collected and tested. Hydration status was evaluated using urine osmolality. Finally, 142 pregnant women completed the study. The median TFIs in the first, second, and third trimesters were 1336, 1477, and 1584 mL, respectively. The TFI levels increased with pregnancy progression (χ2 = 134.155, p < 0.05). Out of 142 participants, 100.0%, 97.2%, and 85.2% of participants did not reach the recommendation amount for an adequate TFI among Chinese pregnant women in the three trimesters, respectively (χ2 = 29.840, p < 0.05). Plain water was the main source of fluid intake, accounting for 92.0%, 94.2%, and 93.4% of TFI, respectively. The median values of dairy product intake were 61, 57, and 59 mL in the three trimesters. The frequency of participants without an optimal hydration status in the three trimesters was 71.8%, 76.1%, and 83.1%, respectively (χ2 = 29.909, p < 0.05). The participants of each trimester were divided into four groups according to quartiles of TFI, including participants with a lower fluid intake (LFI1 and LFI2) and higher fluid intake (HFI1 and HFI2). As the TFI values increased from the LFI1 group to the HFI2 group, the urine osmolality decreased (all p < 0.05). Moderate-intensity negative correlations were found between urine osmolality, hydration status, and TFI (all p < 0.05). It is suggested that fluid intake strategies should be promoted and health education should be conducted to improve the hydration status of pregnant women.
Perinatal water intoxication due to excessive oral intake during labour. [2019]The increased body water in pregnant women and the birth-related activation of water-sparing systems contribute to a high risk of perinatal water intoxication if the mother drinks too much water during labour. This study reports on four newborn term infants and one mother presenting with life-threatening symptoms due to hyponatraemia from excessive oral intake during labour. Awareness of this diagnosis in the delivery unit is very important, because the clinical picture may mimic that of pre-eclampsia or dehydration.
