Baby Smell Visual Stimulus Program Cortical and Breast Oxygenation Milk Amount Mother-Infant Attachment

The Effect of Baby Smell and Visual Stimulus Program on Mothers' Cortical and Breast Oxygenation, Milk Amount and Mother-Infant Attachment: Randomized Controlled Study

In this study, the effect of infant odor and visual stimulus program applied to mothers who had delivered by cesarean section and whose babies were taken to the NICU on cortical and breast oxygenation (rSO2), amount of breast milk and mother-infant bonding was investigated.

One of the conditions that prevent the preterm baby from being close to the mother in the early period is cesarean delivery and subsequent removal to the NICU. In the first hour of life, the process immediately after birth, when the newborn is alert, makes eye contact, focuses, finds the unaided mother's breast and begins to feed, deteriorates in babies in need of intensive care and mothers begin the experience of parenting with delayed attachment. The mother experiences high levels of stress due to changes in many parental roles such as being physically separated from her baby, not being able to breastfeed effectively, not being able to care for her baby and the intensive care environment, and experiencing a delay in lactation with the effect of cesarean delivery. In the literature, many interventions have been implemented to reduce the negative effects of mother-infant separation on lactation and attachment in mothers who have given birth by cesarean section. However, there is no published research examining the effect of infant odor and visual stimulus program applied to mothers who had delivered by cesarean section and whose babies were taken to the NICU on cortical and breast oxygenation (rSO2), amount of breast milk and mother-infant bonding. In addition, being able to assess how the mother's cortical and breast oxygenation changes while smelling her baby's scent and watching her/his video will further strengthen the results of the measurement tools.

In this randomized controlled study, "block randomization" method, which is one of the "fixed probability randomization" methods, was used in randomization. Each of the experimental and control groups was represented by one of the letters A, B, C. In the creation of the 6-block (2A, 2B, 2C) design for 54 samples and three groups; Using the "permutation" method, the assignment of 9 blocks out of 90 block options was carried out through the random numbers table on the www.random.org site. Which of the experimental and control groups will match the letters A, B, C; It was determined by the lottery method drawn by hand by the independent clinical nurse from the study. As a result of the draw, A: smell, B: smell + video, C: represented the control group.

Firstly the baby beret worn by the researcher on the baby will be removed at the end of the 12th hour (at the 12th hour and 24th hour of the hospitalization in the clinic) and taken to the Obstetrics and Gynecology Service on the same floor as the NICU without waiting;Odor stimulation will be applied in the form of 30 sec odor-30 sec standby-30 sec odor-30 sec standby-30 sec odor. A total of 4 rSO2 values, including the initial value and the average of the values during three 30 sec stimulation, will be recorded in the "Cortical and Breast Oxygenation Follow-up Form". The amount of the first amount of milk, the total amount of milk until the 12th hour, the amount of oral fluid intake, the amount of milk until the 24th hour (12th hour -24th hour) and the amount of oral fluid intake will be recorded in the Milk Amount Follow-up Form.

Firstly the baby video (visual stimulus) and beret worn by the researcher on the baby will be removed at the end of the 12th hour (at the 12th hour and 24th hour of the hospitalization in the clinic) taken by researcher and taken to the clinic on the same floor as the NICU without waiting; Once the initial rSO2 value has been recorded, the mother will be instructed to sniff the beret uninterruptedly until further warning by the researcher and to watch the image of her baby unfolding on the tablet fixed to the floor during the entire measurement process. Odor stimulation to the mother will be applied in the form of 30 sec odor-30 sec waiting-30 sec odor-30 sec waiting-30 sec odor respectively, and visual stimulation will be applied as uninterrupted 2.5 min. At the end of 24 hours, the Mother-Baby Interaction Form and the MIBS tool will be re-applied as the final test.

The intervention and data collection process in the control group is the same as the intervention in the odor group; As a placebo instead of odor stimulation, the odorless beret will be offered in the same conditions.

Form; was created by the researcher in accordance with the literature to record cortical and breast oxygenation (Tanimoto et al., 2011; Schafer et al., 2019). NIRS measurement range was accepted as 15-95 for breast and cortical oxygenation. In the study of Tanimoto et al. (2011), the average of the measurement periods of 30 seconds was taken as the initial value; A 5-minute chart has been generated. Similarly in our study; The initial rSO2 value for both cortical and breast will be recorded, and the average rSO2 value for each block will be recorded during 30 seconds of intervention (smell, odor + visual stimulus, control) repeated 3 times. The form contains two charts with 4 cortical and breast rSO2 recordings for the measurement to be made at two different times (12th and 24th hour of birth)

It was created by the researcher in line with the literature (Turhan, 2020). The form will record the amount of initial milking, the total amount of milk up to the 12th hour, and the amount of oral fluid intake, the total amount of milk between the 12th-24th hour onwards, and the amount of oral fluid intake.

The "Mother to Infant Bonding Scale" tool developed by Taylor et al., (2005) was adapted into Turkish by Karakulak Aydemir and Alparslan, (2016). The scale, which is arranged in such a way that it can be applied from the first day after birth and allows the mother to express her feelings towards her baby with a single word, consists of 8 items and is in the form of 4 likerts. The score range of the scale is between 0-24. A high score indicates low bonding.
