epi-gastrum.Associated with decreased activity of the stomach.nVomiting：the forceful oral expulsion of gastric contents via retro-peristalsis.nNausea-Vomiting:simultaneity or separateness恶心：紧迫欲吐，通常伴有上腹不适和迷走兴奋的临床征候群。呕吐：胃和/或小肠内容物经食管和口腔排除体外恶心和呕吐常伴随存在，也可单独出现！恶心呕吐宣讲5Definition of Nausea and VomitNausea and Vomiting恶心呕吐宣讲6Nausea and Vomiting恶心呕吐宣讲61、恶心：咽部及上腹部不适，胃张力和蠕动减弱，幽门和贲门开放。2、干呕：胃窦部和腹壁肌肉收缩，腹压增加，食管及咽部开放。3、呕吐：胃和/或小肠内容物经食管和口腔排除体外。Definition of emesis.(Three phases)呕吐反射过程（三个阶段）1.Nausea-the inclination or feeling of imminent desire to vomit,usually felt in the throat or epigastrum.Associated with decreased activity of the stomach.2.Retching-the labored rhythmic contraction of respiratory and abdominal musculature that frequently precedes or accompanies vomiting.3.Vomiting-the forceful oral expulsion of gastric contents via retroperistalsis.(Abdominal
