Could the ratio of the second finger to the fourth finger (2D:4D) be a new morphological marker in predicting preoperative anxiety and postoperative agitation in pediatric patients?

Studies have reported that the ratio of the second finger to the fourth finger (2D:4D) indicating the effects of intrauterine andogene exposure. It is stated that it can be used as a morphological marker in evaluating developmental/ psychopathological disorders. 90 children between the ages of 5-10, who were planned to undergo deciduous tooth extraction under deep sedation, were included in the study. Measurements were made on the second and fourth fingers of children's right and left hands. The behaviors of the patients during the preoperative period (m-Yale Preoperative Anxiety Scale), vascular access insertion and separation from the family were evaluated in determining the anxiety levels of the patients. During the recovery process, agitation status was evaluated using Watcha Scale. And there was no significant relationship found between 2D:4D and these parameters. In conclusion, 2D:4D did not succeed as a morphological marker in predicting preoperative anxiety and postoperative agitation in the preoperative period.
