The length of gastric tube insertion during gastric lavage is usually around 50~60 cm in adults, and the length in pediatric groups is uncertain and can be tested on site.
Gastric lavage is one of the commonly used clinical operations. For patients with pyloric edema or overdose of drugs, etc., gastric lavage can be performed by inserting a gastric tube in order to improve the pyloric edema or to reduce the effect of drugs.
Generally choose the nasogastric tube, the length of the nasogastric tube is about 100 centimeters, you need to insert the nasogastric tube from the nasal cavity, after inserting it into the stomach, it will be suctioned through the syringe, and after suctioning to the stomach contents, the gastric lavage operation can be carried out.
The depth of insertion is usually around 50-60 cm in adults, while it is uncertain in the pediatric population. A gastric tube or catheter can be taken and passed along one side of the pediatric earlobe to the tip of the nose and then to the xiphoid process, and the depth of insertion of the gastric tube can be roughly determined by measuring this data.
Care should be taken when inserting the gastric tube so that it is not done violently to minimize injury to the patient. During gastric lavage, attention should also be paid to the speed of liquid injection and extraction to prevent rapid expansion or contraction of the stomach and discomfort to the patient.
