Vaseline Gauze turned out to have this use. Several medical students listened to the teacher's experience talk and felt enlightened.
On the contrary, Yao Jie nearly rolled her eyes upon hearing that oil gauze strips were needed. She had forgotten which box she had put them in at the bottom. She could only rummage through a dozen boxes, sweating and turning everything upside down.
"Yao Jie," Xie Wanying noticed her unusual expression and told her, "I stuffed a box of Vaseline Gauze next to the one against the wall. Take it out and let Teacher Nie use it first."
Xie Xie! Yao Jie gave her a grateful look and hurriedly ran into the office to fetch the item.
Following the teacher's instructions, Xie Wanying placed Vaseline Gauze in the child's wound, and after finishing up, she told the family, "You need to bring the child in for a dressing change every day."
"Are you going to be the one who changes it?" the child's grandfather asked her.
