1. Preoperative fasting for the infusion of “yerba mate”: a randomized clinical trial with ultrasound evaluation of gastric contents
Abstract Background The traditional infusion of “yerba mate” is widely consumed in South America and exported to countries around the world. Although generally considered a “clear fluid”, there is no data to date on the gastric emptying time of yerba mate and safe preoperative fasting intervals. The objective of this study was to evaluate the gastri

2. The clinical impact of the systolic volume variation guided intraoperative fluid administration regimen on surgical outcomes after pancreaticoduodenectomy: a retrospective cohort study
Abstract Background Pancreaticoduodenectomy is associated with high morbidity. Many preoperative variables are risk factors for postoperative complications, but they are primarily non-modifiable. It is not clear whether an intraoperative goal-directed fluid regimen might be associated with fewer postoperative surgical complications compared to current conse

3. Ultrasonographic evaluation of gastric content and volume: a systematic review
RESUMO OBJETIVO: A broncoaspiração do conteúdo gástrico associa-se à alta morbimortalidade, porem a avaliação desta complicação é tarefa dificil. Por outro lado, a ultrassonografia gástrica avalia o conteúdo gástrico com segurança, podendo evitar a broncoaspiração. Portanto, foi realizada revisão sistemática com objetivo de verificar a apl

4. A newly validated HPLC–DAD-UV method to study the effects of medicinal plants extracts, fractions and isolate compounds on gastric emptying in rodents
Abstract In this study, we developed and validated a chromatographic method by High-performance Liquid Chromatography coupled to Diode-Array Ultraviolet Detector for quantification of acetaminophen in small volumes of plasma. This analytical method is particularly suitable for studies of gastric emptying time and pharmacokinetics in small rodents. Orally adm

5. Comparative ultrasound study of gastric emptying between an isotonic solution and a nutritional supplement
Resumo Justificativa e objetivos: O jejum pré-operatório pode levar a efeitos indesejáveis no paciente cirúrgico, em que há um estimulo à ingestão de líquidos sem resíduos até 2 horas antes da anestesia. O objetivo deste estudo foi avaliar o esvaziamento gástrico de duas soluções diferentes por meio da ultrassonografia. Métodos: Em um estudo

6. Effects of dipyrone on the digestive tract
Dipyrone (metamizole), acting through its main metabolites 4-methyl-amino-antipyrine and 4-amino-antipyrine, has established analgesic, antipyretic, and spasmolytic pharmacological effects, which are mediated by poorly known mechanisms. In rats, intravenously administered dipyrone delays gastric emptying (GE) of liquids with the participation of capsaicin-se

7. Acute exercise inhibits gastric emptying of liquids in rats: influence of the NO-cGMP pathway
We previously found that acute exercise inhibited the gastric emptying of liquid in awake rats by causing an acid-base imbalance. In the present study, we investigated the involvement of the nitric oxide-cyclic guanosine monophosphate (NO-cGMP) pathway, vasoactive intestinal peptide (VIP), and corticotropin-releasing factor (CRF) peptide in this phenomenon.

8. Laparoscopic versus open pylorus-preserving pancreatoduodenectomy. The first meta-analyse of retrospective matched cases
Abstract Purpose: To compare the safety, feasibility, and short-term clinical benefits of laparoscopic pylorus-preserving pancreaticoduodenectomy (L-PPPD) to open pylorus-preserving pancreaticoduodenectomy (O-PPPD) through retrospective matched cases. Methods: Web of Science, Cochrane, PubMed, CNKI were searched systematically identify studies published b

9. Dipyrone in association with atropine inhibits the effect on gastric emptying induced by hypoglycemia in rats
Atropine (AT) and dipyrone (Dp) induce a delay of gastric emptying (GE) of liquids in rats by inhibiting muscarinic receptors and activating β2-adrenergic receptors, respectively. The objective of the present study was to determine the effects of pretreatment with AT and Dp, given alone or in combination, on the effect of hypoglycemia in the liquid GE in ra

10. Effects of the Addition of Glucose, Sodium Bicarbonate, and Vitamin E to the Drinking Water of Pre-Slaughter Broiler Chickens on Carcass Yield, Gastric Emptying and Meat Quality
ABSTRACT An experiment was conducted of the poultry facilities of La Salle Agricultural College in Xanxerê, SC, Brazil, to evaluate the effect of the administration of sodium bicarbonate, glucose and vitamin E to the drinking water during pre-slaughter feed withdrawal on carcass yield, organ relative weights (heart, liver, proventriculus, and gizzard), gizz

11. Effect of selective β-adrenoceptor blockade and surgical resection of the celiac-superior mesenteric ganglion complex on delayed liquid gastric emptying induced by dipyrone, 4-aminoantipyrine, and antipyrine in rats
There is evidence for participation of peripheral β-adrenoceptors in delayed liquid gastric emptying (GE) induced in rats by dipyrone (Dp), 4-aminoantipyrine (AA), and antipyrine (At). The present study aimed to determine whether β-adrenoceptors are involved in delayed GE induced by phenylpyrazole derivatives and the role of the prevertebral sympathetic ne

12. Fasting does not induce gastric emptying in rats
PURPOSE: To evaluate the effect of fasting on gastric emptying in mice.METHODS:Twenty-eight mice were distributed into three study groups: a normal group (N=4): normal standard animals; a total fasting group (N=12): subjected to food and water deprivation and a partial fasting group (N=12): subjected to food deprivation only. The fasting groups were subdivid
