什么是胃吸力？

Gastric suction, or stomach pumping, is a procedure your doctor can perform to empty the contents of your stomach quickly during an emergency. It’s also known as gastric lavage and nasogastric tube suction.

如果您吞咽毒药或服用过量服用药丸，您的医生可能会点胃吸力。如果您吞咽了一些有毒的东西，例如家用化学物质，请尽快去医院。如果胃吸力在摄入有毒物质的四个小时内进行，则最成功。一旦毒药进一步进入您的消化道，执行此过程就不会删除它。

Your doctor may also order gastric suction after certain surgeries on your abdominal area, such as agastrectomy。此过程涉及部分或完全切除您的胃。胃吸力可以帮助您在愈合时保持胃空。在这种情况下，您不会吃固体食品，因此只有稀薄的液体才能进入您的胃。低水平的吸力将用于去除流体。

Your doctor may also use gastric suction to:

  • 收集胃酸样品
  • 如果您的肠子被阻塞，请减轻肠道的压力
  • 如果您的胃出血，抽血
  • clean out your stomach if you’re vomiting blood during an upper gastrointestinal (GI) endoscopy, which is a procedure in which your doctor inserts a scope down your esophagus to examine your upper GI tract
  • 安全进行手术并限制肺炎的抽吸风险
  • 在医院环境中的辅助通风期间解压缩胃

If you’re undergoing gastric suction because of poisoning, drug overdose, or other emergency situations, you won’t have time to prepare for it beforehand. But if your doctor orders gastric suction to collect a sample of your stomach acid for testing, they may ask you to fast or avoid taking certain medications before the procedure.

Before the procedure, your doctor may give you medicine to numb your throat. This will help decrease gagging and irritation. Then, they’ll insert a lubricated tube into your mouth or nose and thread it down through your esophagus into your stomach. Your esophagus is the tube that connects your mouth to your stomach.

Your doctor may spray water or saline solution down the tube before applying suction. Saline solution can help protect you against electrolyte imbalances that can occur when your doctor removes fluids from your stomach. They’ll then apply suction to remove your stomach contents.

If you have the tube inserted while you’re recovering from abdominal surgery, your doctor will likely leave it in while you heal. A nurse will probably irrigate the tube regularly with saline solution. This helps to keep the tube open and prevent blockages.

This procedure can be uncomfortable. You may feel like gagging while they insert the tube. Afterward, your throat may feel irritated.

This procedure also poses more serious risks. One of the most common isaspiration pneumonia。This happens when some of your stomach contents enter into your lungs or airways. Untreated aspiration pneumonia can potentially lead to lung swelling, lung abscesses, or bacterial pneumonia. The symptoms of aspiration pneumonia include:

  • chest pain
  • 喘息
  • coughing up phlegm
  • 皮肤的蓝色色彩
  • exhaustion
  • a fever

如果管脱落，则会发生这种风险。胃吸力可以通过清空胃来保护您免受吸入性肺炎的影响，然后才能进入呼吸道。

Other risks of gastric suction include:

  • 声带的痉挛，暂时防止正常呼吸
  • 管进入您的气道而不是食道
  • 管子在您的食道上戳一个孔
  • 胃内容物被进一步推入肠子
  • 小提单eeding
