ContextThe addition of glutamine in preoperative drinks may enhance the benefits of carbohydrate alone.ObjectivesTo evaluate the gastric residual volume after the intake of a beverage containing carbohydrate plus glutamine.MethodsEleven healthy volunteers (24-30 years-old) were randomized in a crossover fashion to intake 400 mL (4h before) and 200 mL (2h before) of a beverage containing either 12.5% maltodextrin (carbohydrate group) or 12.5% maltodextrin plus 15 g of glutamine (glutamine group) in two different moments 7 days apart. Magnetic ressonance was performed to measure the gastric residual volume (mL) 120 and 180 minutes after the last ingestion.ResultsGastric residual volume similar to basal condition was found after 2h and 3h of the intake of beverages. There was no difference in the mean ±SD GRV (mL) found at 120 minutes (carbohydrate group: 22.9±16.6 and glutamine group: 19.7±10.7) and at 180 minutes (carbohydrate group: 21.5±24.1 and glutamine group: 15.1±10.1) between the two drinks.ConclusionsGastric emptying is efficient, and occurs in up to two hours after the intake of a beverage containing either carbohydrate alone or carbohydrate associated with glutamine. The addition of glutamine to carbohydrate-enriched drink seems to be safe for the use up to 2h before an operation. HEADINGS - Gastric emptying. Preoperative care. Carbohydrates. Glutamine.

RESUMOO presente relato de caso aborda uma complicação rara de uma patologia obstétrica, a temida síndrome HELLP (Hemolysis, Elevated Liver enzymes and Low Platelets), tendo como objetivo principal associar possíveis cenários clínicos da doença supracitada ao quadro de colecistite aguda alitiásica.
Introdução: casos de COVID-19 (doença infecciosa causada pelo Coronavírus e diagnosticado em 2019) podem apresentar-se de formas inespecíficas e incomuns, sendo a ruptura esplênica atraumática um diagnóstico diferencial incluso nesses pacientes. Relato do caso: paciente com diagnóstico de COVID-19, internada em enfermaria, evoluindo com choque hemorrágico por ruptura esplênica atraumática. Discussão: ruptura atraumática do baço é uma situação rara, que pode ocorrer, entre outros motivos, devido doenças infecciosas, sendo potencialmente grave com risco elevado de óbito. Há evidências que sugerem que a COVID-19 causa impacto direto no baço, causando trombose microvascular e necrose. A lesão esplênica faz parte do diagnóstico diferencial em pacientes infectados pelo SARS-CoV-2 (sigla em inglês para Síndrome Respiratória Aguda Grave causada pelo Coronavírus 2) que evoluem com dor abdominal e alterações hemodinâmicas.
