Brief summary
Awareness during anesthesia with intraoperative memory occurs when the patient is able to process information and produce specific responses to several stimuli. Anecdotal evidence suggests that children exposed to therapeutic suggestion consisting of gently encouraging, positive words spoken to them during emergence from anesthesia seem to arouse after surgery with less agitation, less pain and lower requirements for pain medications. Therapeutic suggestion has been associated with positive results in some adults during surgery, but it is unknown how therapeutic suggestion affects children. A newborn's recognition and preference for their mother's voice occurs early in life, very likely during fetal development. Additional evidence, revealed that at least as early as 4 months of age, infants process auditory stimuli from their mother's voice at a higher amplitude than they process auditory input from female strangers, suggesting that maternal voice stimuli undergo a unique form of cerebral processing that lends support for the existence of neurophysiologic mechanisms that reflect a child's preference for his/her mother's voice. This study aims to evaluate and compare the possibility of intra-operative awareness prevention by using either music listening or maternal sound listening in children undergoing cardiac surgery.
Detailed description
children (4 to 8 years) undergoing repair of Atrial Septal Defect (ASD). Patients will be randomized into two groups (music group and maternal sound group); in music group patients listened to a recorded CD by music and songs preferred by the child, while in maternal sound group patients listened to a recorded CD where the mother singing the most popular songs their children like or telling a story to their children. In both groups bi spectral index (BIS) to detect depth of anesthesia. An interview will be conducted with the patients and their parent within the first postoperative week by a semi-structured in-depth questionnaire to evaluate occurrence of awareness.
Interventions
BEHAVIORALMusic sound
The recorded preferred songs or music (commercially available) listened by CD player connected to the patient ears before induction of anesthesia and continued during intra operative period
BEHAVIORALMaternal sound
The recorded maternal voice (while they are singing the most popular songs their children like or telling a story to help their children to sleep) listened by CD player connected to the patient ears before induction of anesthesia and continued during intra operative period
