其次，患者因术后需要给予肠内营养，术前在病房经左侧鼻腔留置胃管，术中气

Secondly, the patient needs to be given enteral nutrition after the operation. Before the operation, a gastric tube was placed in the ward through the left nasal cavity, and the tracheal tube was placed through the right nasal cavity during the operation. If the two tubes are switched laterally, will it bring different results? ? If so, what changes will the perioperative surgical team need to make? During the operation, the patient's head is inclined to the unaffected side. The placement of the sterile dressing sheet and the operation of the forearm by the doctor during the operation will inevitably bring continuous pressure. Therefore, the tracheal tube with a larger diameter is inserted through the nasal cavity of the unaffected side. The thinner and softer gastric tube is inserted through the nasal cavity of the affected side, which will reduce the shear force on the compressed part from the outside world, thereby reducing the risk. Of course, this depends on the communication and cooperation of the surgical team during the perioperative period.

Secondly, the patient needs to be given enteral nutrition after operation. Before operation, the gastric tube is indwelling through the left nasal cavity in the ward, and the endotracheal tube is placed through the right nasal cavity during operation. Will it bring different results if the two tubes are exchanged laterally? If so, what changes do the perioperative surgery team need to make? During the operation, the patient's head is inclined to the healthy side, and the laying of sterile dressing sheet and the doctor's operation of forearm during the operation will inevitably bring continuous pressure. Therefore, inserting the tracheal tube with thicker diameter through the nasal cavity of the healthy side, and inserting the gastric tube with thinner diameter and softer material through the nasal cavity of the affected side will reduce the external shear force on the compressed part, so as to reduce the risk, Of course, this depends on the perioperative communication and cooperation of the surgical team.

Before operation, the gastric tube was placed in the ward through the left nasal cavity, and the tracheal tube was placed through the right nasal cavity during operation. If the two tubes were exchanged laterally, would it bring different results? If so, what changes should the perioperative surgical team make? During the operation, the patient's head leans to the healthy side, and the laying of sterile dressing sheet and the operation of doctors' forearms during the operation will inevitably bring continuous pressure. Therefore, inserting the tracheal tube with larger diameter through the healthy side nasal cavity, and inserting the gastric tube with smaller diameter and softer material through the affected side nasal cavity, will reduce the external shearing force on the compressed part, thus reducing the risk. Of course, this depends on the communication and cooperation of the operation team during the perioperative period.
