The Efficacy of Maternal Sound for Pediatric Patients Undergoing Cardiac Surgery

Children (4 to 8 years) undergoing repair of Atrial Septal Defect (ASD). Patients will be randomized into two equal groups (30 in each group) (control group and maternal sound group); in control group patients listened to a blank CD, 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. Baseline stress markers (blood glucose and plasma cortisol) sampled the morning before scheduled operation. A interview with the patients and their parents before operation to collect the questionnaire regarding patient's characteristic (age, sex, weight and height), patient's clinical data (medical diagnosis and American Society of Anesthesiologists physical status) and haemodynamic data (blood pressure, heart rate, oxygen saturation on room air, temperature). In addition, the researcher interviewed with the mothers to record on one CD their voice while they are singing the most popular songs their children like or telling a story to their children to help them to sleep to be used during intra-operative period in maternal sound group.
