Study on the Effect of Eye-covering Pretreatment on Acute Delirium After General Anesthesia in Pre-school Aged Children

Participants (preschool children), because their cognitive ability and anti pressure ability are obviously weaker than adults, most of the children who have this kind of operation and anesthesia stressors will have perioperative anxiety. After eye surgery, they need to bandage their eyes with gauze (single or double), so that the participants are in a state of complete or partial darkness for a certain period of time, which is easy to produce dark phobia. In clinical practice, investigators found that more than 80% of children with advanced ophthalmology were prone to leprosy, resistance, crying and other symptoms after general anesthesia, which brought greater difficulties to nursing. How to improve the cognitive ability of preschool children, reduce the anxiety level of children during the perioperative period, the incidence of postoperative detention and the difficulty of nursing are new topics worthy of exploration.
