Evaluation of Cerebral Oxygenation Results in Premature Infant

Evaluation of Cerebral Oxygenation Results in Premature Infants: Kangaroo Care and Facilitated Tucking Example

The general purpose of this project is; Evaluation of cerebral oxygenation results in premature infants. These results will be evaluated in two different applications. The first practice and the first sub-aim of the study is to determine the effect of kangaroo care on cerebral oxygenation (rSO2) in premature infants. The second application and purpose is to determine the effect of giving the infant the facilitated tucking position by hand and the nesting bed on the cerebral oxygenation (rSO2) of the infant during the heel blood collection process. The study will be conducted between December 2020 and December 2021 at Level III NICU at the Medical Faculty Hospital in Konya.

The general purpose of this project is; To determine the effect of kangaroo care and facilitated tucking position on cerebral oxygenation (rSO2) in premature infants. In this context, the study has two sub-objectives. First sub purpose; to determine the effect of kangaroo care application given to premature inafants hospitalized in the NICU with the mother on cerebral oxygenation (rSO2), physiological parameters (heart rate, peripheral oxygen saturation (SpO2) and respiratory rate) and comfort / comfort levels. This study was designed as a single blind, parallel group, pre-test and post-test randomized controlled trial. First sub purpose; total sample size was determined as 40 preterm babies (20 in each group). Block randomization was used in this study. During the data collection phase, the purpose of the study will be explained to the parents of preterm infants by the researcher, and written consent will be obtained from the parents who agree to participate in the study through the "Informed Consent Form". Introductory Information Form, Physiological Parameter and rSO2 Follow-up Chart and Neonatal Comfort Scale created by the researcher will be used. Second sub purpose; to determine the effect of facilitated tucking position on the infant's cerebral oxygenation (rSO2), physiological parameters (heart peak beat, SpO2 and respiratory rate), pain and comfort / comfort levels during the heel stick procedure. This study was designed as a single blind, parallel group, two intervention groups in pre-test and post-test order, and a randomized controlled control group. Second sub purpose; the total sample size was determined as 66 (22 in each group). Block randomization was used in this study. During the data collection phase, the purpose of the study will be explained to the parents of preterm infants by the researcher, and written consent will be obtained from the parents who agree to participate in the study through the "Informed Consent Form". The Introductory Information Form, Physiological Parameters and rSO2 Tracking Chart, PIPP-R and Neonatal Comfort Scale created by the researcher will be used.

First sub purpose was designed as a single blind, parallel group, randomized controlled pre-test post-test order. Second sub purpose was designed as a single blind, parallel group, two intervention groups in pre-test and post-test order, and a randomized controlled control group.

No Intervention: Standard care The control group will be followed by infants using nesting in the incubator. It will be followed for 60 minutes without any action or application. Experimental: Kangaroo care The mother kangaroo will care for at least 60 minutes.

No Intervention: Standard care In the Control Group, the heel stick procedure will be performed in the infants own bed as in the clinical routine. Experimental 1: Manual Facilitated Tucking Position, infants will be given a manual facilitated tucking position during the heel stick procedure. Experimental 2: Facilitated Tucking Position, with the Nesting Bed (Tortoise Neo Bed), the facilitated tucking position will be given by the clinic nurse with the nesting bed during the heel stick collection procedure.

Defines the change of rSO2 level. The NIRS monitor (COVIDEN Operations Manual INVOS® System, Model 5100C) was used to monitor rSO2 levels. The normal range of the rSO2 measured by the device was between 55% and 85%.

Defines the change of heart rate (min) level.Philips IntelliVue MP40 device was used to monitor respiratory rate. Philips IntelliVue MP40 device was used to monitor heart rate (min).

The COMFORTneo scale is a Likert-type scale consisting of seven parameters: alertness, calmness/agitation, respiratory response, crying, body movements, facial tension, and muscle tonus. The items are rated between 0 and 10, and the score that can be obtained from the scale ranges between 6 and 30. A score of 4-6 indicates moderate pain and distress and that of 7-10 indicates severe pain and distress.

The first sub-purpose Outcome: physiological parameters of the premature infant-respiratory rate (min)

The PIPP-R scale includes 3 behavioral (frowning, squeezing eyes, nasolobial-groove), 2 physiological (heart rate and oxygen saturation) and 2 contextual (behavioral state and gestational age) items used in the assessment of pain in newborns. The items of the scale are scored as 3, 2, 1, 0 ((0-6 points that the pain is mild, 7-12 points is moderate, and 13-21 points is at a severe level.)

The scale consists of 7 items: muscle tone, alertness, facial tension, calmness / agitation, body movements, respiratory response, and crying. The lowest possible score from Newborn Comfort Behavior Scale is 6 and the highest score is 30. High scores indicate that the baby is not comfortable.

The second sub-purpose Outcome: physiological parameters of the premature infant- oxygen saturation (%SpO2)

Defines the change of rSO2 level. The NIRS monitor (COVIDEN Operations Manual INVOS® System, Model 5100C) was used to monitor rSO2 levels. The normal range of the rSO2 measured by the device was between 55% and 85%.
