Effect of Muscle Relaxants on Eye Position in Children with Exotropia During General Anesthesia
Objective To investigate the effect of muscle relaxation drugs on the eye position of children with exotropia under general anesthesia.Methods A total of 80 children with exotropia aged 2 to 12 years old who were expected to undergo general anesthesia(intravenous administration)surgery in the author's hospital during the three years from September 2021 to March 2023 were selected as the study objects.The patients were divided into group A and Group B according to whether muscle relaxants were used or not,with 40 cases in each group.Group A received muscle relaxants and group B did not receive muscle relaxants.The eye position of the children under shallow,medium and deep anesthesia was measured by keratorimetry before and immediately after anesthesia,and the eye position of the children under shallow,medium and deep anesthesia was measured by BIS during operation.Results The external inclination of the eye measured by keratography immediately after anesthesia in both groups was higher than that before anesthesia,but the external inclination of the eye in group A was lower than that in group B(P<0.05).There was A statistical difference between the two groups in BIS monitoring eye position under different anesthesia depths.With the increase of anesthesia depth,the external inclination of eye position increased,and the external inclination of eye position under each anesthesia depth was smaller in group A than in group B(P<0.05).Conclusion General anesthesia can affect the eye position of children with exotropia,but the use of muscle relaxants can weaken this effect.Different depth of anesthesia can also affect the eye position of children.Compared with moderate anesthesia and deep anesthesia,the eye position of children in light anesthesia is less affected.
