Effect of Using White Noise, Embracing and Facilitated Tucking in Newborns
Condition: Pain
Study type: Interventional

Summary: 
      This study was conducted to evaluate the effect of using white noise, embracing and
      facilitated tucking on physiological parameters, crying duration and pain during heel lance
      blood sampling in healthy newborns.

      This study was a prospective, randomized controlled trial. The study was conducted with
      healthy newborns who were born between 38 and 42 weeks of gestation. The newborns were
      divided into 4 groups by the applied pain relief methods during heel lance blood sampling in
      newborns; embracing(n=40), white noise(n=40), facilitated tucking(n=40) and control group
      (n=40). The physiological changes were evaluated before and after the procedure. NIPS
      (Neonatal Infant Pain Scale) was used for pain scoring.
    

Detailed description: 
      This study aimed to investigate the effect of white noise, embracing and facilitated tucking
      on pain during heel lance blood sampling in newborns.

      METHODS This randomized-controlled experimental study was performed to evaluate the effect of
      white noise, embracing and facilitated tucking on pain during heel lance blood sampling in
      newborns.

      Setting and sample:

      The study sample consisted of healthy newborns who were born and monitored in the Neonatology
      Unit of a university hospital. The sample inclusion criteria were gestational age between 38
      and 42 weeks, birth weight of 2500 - 4000 g, Apgar score of 8 and higher at 1st and 5th
      minute, having breastfed at least half an hour before the procedure, not showing any disease
      symptom, not having congenital anomaly, getting a good hearing test result and not having
      received any invasive intervention other than Vitamin K and Hepatitis B vaccine.

      Sample size:

      Following previous studies, G*Power (v3.1.9.2) was deployed to determine the sample number.
      According to Jacob Cohen's effect size coefficients, assuming that evaluations carried out
      among four independent groups would have a large effect size (d=0.40), it was determined that
      the groups should comprise least 40 people, with a total of 160, for levels of α=0.05 and
      1-β=0.95 (80% power). Children were assigned to 4 subgroups through randomization performed
      using a computer program (www.randomizer.org): group 1 was the control group children who
      received no intervention for pain relief (n = 40); group 2 received facilitated tucking (n =
      40); group 3 received embracing (n = 40); and group 4 received white noise (n = 40).

      Intervention:

      The mothers were informed by the researcher about the purpose of the study before collecting
      data. The infants were held by their mothers so that their faces, arms, legs and respirations
      could be easily viewed by the camera to evaluate the NIPS. All heel lance procedures were
      performed by the same nurse working on the day shift (who had 6-year NICU experience). The
      heel lance blood sampling point (outer side of the left heel), the lancet used in the
      procedure, the sampling technique, and the antiseptic solution (70% alcohol) used in for the
      procedure were the same for all the groups. The heel lance blood sampling procedure was
      performed by the researcher in the blood sampling room in the Neonatology ward. Suitable
      environmental conditions (ambient temperature, silent environment, etc.) were ensured in the
      study room for the infant's comfort. A saturation probe was inserted to the right wrist of
      the infant to monitor him/her. The behavioral responses to pain and crying durations of all
      the responses were recorded by camera before, during and after the procedure. Then, these
      records were played and the NIPS scores and crying durations of the infants were evaluated.
      The physiological changes were recorded before, during and after the procedure, respectively.
      In the data collection stage, 3 persons (nurse putting the infant in facilitated tucking
      position, nurse taking blood sample, researcher shooting video) were required for facilitated
      tucking position; 2 persons (nurse taking blood sample and researcher shooting video) for
      maternal embracing since the infant was held by the mother and 2 persons (nurse taking blood
      sample and researcher shooting video) for white noise.

      Heel Lance Blood Sampling in Facilitated Tucking Position:

      The infants were put in facilitated tucking position by an experienced newborn nurse. They
      were put in facilitated tucking position so that their arms and legs were in a flexed midline
      position close to their trunk in a side-lying position. They were positioned so that they
      could move their extremities freely. They were held in facilitated tucking position for 120
      seconds before the procedure. They were kept in facilitated tucking position until the blood
      sample was taken from the right heel using a lancet. They were released 60 seconds after the
      procedure and monitored for 120 seconds. The blood samples were taken by the researcher after
      inserting the lancet in the first try.

      Heel Lance Blood Sampling When the Infant is Embraced by the Mother:

      The mother, whose privacy was protected, embraced the infant for 120 seconds before the
      procedure. The infant was embraced by the mother during the heel lance blood sampling from
      the left heel using a lancet. They were released 60 seconds after the procedure and monitored
      for 120 seconds. The blood samples were taken by the researcher after inserting the lancet in
      the first try.

      Heel Lance Blood Sampling Using White Noise:

      The 'Don't Let Your Baby Cry, PT.2' track from the 'Colic' album by Orhan Osman using the
      'The Happiest Baby' album by Dr. Harvery Karp which was composed only of intrauterine was
      made listened to the infants via Xperia Ultra Mp3 Player for 120 seconds before and 120
      seconds after the heel lance blood sampling procedure. While white noise was made listened to
      the infants before, during and after the procedure, Digital Sound LeverMeter brand noise
      measurement device was put at a distance of 50 cm from the infant and the ambient noise level
      was adjusted as 55 dB. The blood samples were taken by the researcher after inserting the
      lancet in the first try.

      Control Group:

      Suitable environmental conditions (ambient temperature, silent environment, etc.) were
      ensured in the study room for the infant's comfort. A saturation probe was inserted to the
      right wrist of the infant to monitor him/her. A video record was taken for 120 seconds
      without any intervention to the infants before and after the heel lance blood sampling
      procedure. The blood samples were taken by the researcher after inserting the lancet in the
      first try. Heel lance was performed in clinical routine for preterm infants in the control
      group.
