Description: Fear and anxiety due to separation from parents during hospitalization of children has been well documented. The young child does become acutely distressed during hospitalization when separated from their primary caregiver (Bowlby, 1952; Robertson, 1958). Many hospitals have changed their visitation policies to allow for greater visitation by parents; however, sometimes they can not be with their child. At such times an intervention that would ease the effects of separation due to hospitalization would be beneficial. One intervention is the playing of audiotapes brought from the home, particularly recordings of parent voices. The specific aims of the study are to determine the effects of a maternal voice audiotape on the behavior and parasympathetic tone of 3 to 5 year old children experiencing short stay surgery.

An experimental pre-test post-test control group design was used to study sixty 3 to 5 year old children experiencing uncomplicated myringotomy tube insertion. The sample included a majority of male children (72%) who lived with their biologic mother and father (87%) and had not been previously hospitalized (69%). The children were randomly assigned to hear a 10 minute tape made by their mother, a 10 minute children's story recorded by an unknown female, or a no-story group. The three groups did not differ significantly in age, height, weight, blood pressure, heart rate or respiratory rate. Each child was observed for 15 minutes in the post anesthesia care unit. Their behaviors were recorded every thirty seconds according to the Sleep Onset Latency Behavior Catalogue (SOL) (White et al., 1983). Parasympathetic tone was measured, using heart rate variability, from a 15 minute recording of cardiac rhythm (Porgues, 1983).

Data analysis identified that the mother's voice group demonstrated fewer distress behaviors than the other groups but the difference was not statistically significant (X$\sp2$ = 2.42, p =.298). A majority of the distress behaviors were demonstrated by only 19 of the subjects. The 19 most distressed children had fewer previous hospitalizations (n = 17, 89%). There was no statistically significant difference in the change in slopes for heart rate variability from the 5 minute baseline period to the 10 minute intervention period between groups (F =.98, p =.381).

Results demonstrated a low number of distress behaviors overall but this study quantified the child's behavior instead of relying on parental report as in previous studies. Future research is needed to determine the amount and type of distress experienced by young children in response to hospitalization. There appears to be a positive impact of past experience with hospitalization on the child's behavior. Further study is needed to determine what it is about previous experience that is helpful and what type of information can be given to children prior to their first hospitalization that can help them deal positively with their initial experience.
