Because both the basal gastric secretion test and the gastric acid stimulation test require insertion of a gastric tube (intubation) through the mouth or nasal passage, neither test is recommended for patients with esophageal.
YesThe ff are considered postoperative causes:General anesthesia, Intubation (stimulation of glottis), Neck extension (stretching phrenic nerve roots), Gastric distention, Traction on viscera.
The least reliable sign for diagnosing esophageal intubation is the presence of breath sounds over the stomach. While breath sounds can indicate proper placement in the lungs, they may also be heard in the case of esophageal intubation due to air entering the esophagus, leading to misinterpretation. More reliable indicators include the absence of breath sounds in the lungs and the presence of gastric sounds. Confirmation via capnography or visualization of the endotracheal tube placement is preferred for accuracy.
No it can not.
A key feature of Rapid-Sequence Induction (RSI) is the application of manual pressure to the cricoid cartilage, often referred to as the "Sellick Maneuver", prior to instrumentation of the airway and intubation of the trachea. Named for British anesthetist Brian Arthur Sellick (1918-1996) who first described the procedure in 1961, the goal of the Sellick maneuver is to minimize the possibility of regurgitation and pulmonary aspiration of gastric contents.
A nasogastric tube is placed through the nose and into the stomach.Nasogastric intubation
Neither. An NG tube is a nasal gastric tube which is inserted through the nose extending into the stomach to evacuate the stomach contents. An OG tube goes down the throat into the stomach for the same reason. Now there can be a nasal intubation if there is oral surgery being done.
absence of ventillation
Placement of a tube into a hollow organ (such as the trachea).
Gastric juice is produced in the stomach. Gastric juice is produced in the Gastric glands.
