Effect of Music Therapy on Pre-term Infants

Abstract

INTERVENTION: in classical music situation,0.5 to 1 hr after nutrition we start observation.2 cameras record dependent variables.10 min after start, classical music(Baby Mozzart) is played through 2 speakers, located at incubater corners,with 30 cm of infant's head, in 45‐50 dl for 20 min.observation lasts 20 min after music. this situation for every infant includs 2 consecutive days. in control situation.every infant is observed 40 min,start 0/5 to 1 hr after nutrition.2 cameras record dependent variables.this situation for every infant includs 2 consecutive days. Intervention 1: This study is crossover and every sample is observed one time as control and two anothrt times as intervention groups. every situation lasts for two days. intervention situations include lullaby and classical music and for every situation two days. observaton time in all situations is 40min every day.it starts 10min before music in intervention groups and continues for 20min music time and 10min after music. in lullaby situation,0.5 to 1 hr after nutrition we start observation.2 cameras record dependent variables.10 min after start, lullaby is played through 2 speakers, located at incubater corners,with 30 cm of infant's head, in 45‐50 dl for 20 min.observation lasts 20 min after music..this situation for every infant includs 2 consecutive days.

CONDITION: Certain conditions originating in the perinatal period physiologic parameters and sleep/awake status. ; Certain conditions originating in the perinatal period PRIMARY OUTCOME: Blood pressure. Timepoint: every 5 min for before, simultaneous and after intervention periods. Method of measurement: with osilometric method and bedside monitoring based on mmhg. Heart rate. Timepoint: every 2 min for before, simultaneous and after intervention periods. Method of measurement: with bedside monitoring. O2saturation. Timepoint: every 2 min for before, simultaneous and after intervention periods. Method of measurement: based on saturated Hb percentile, with pulseoximeter. Respiration rate. Timepoint: every 2 min, for before, simultaneous and after intervention periods. Method of measurement: respiration rate in 1 min,with observation. Sleep/awake status. Timepoint: every 2 min for before, simultaneous and after intervention periods. Method of measurement: includ 6 stages based on Brazelton sleep/awake statuses.
