Effect of Nesting During Intramuscular Injection on Pain, Stress, and Breastfeeding Success in Cesarean-Born Term Newborns (NESTING)

2. august 2026 opdateret af: Emine Nur Çalımlı Celep, Istanbul University - Cerrahpasa

The Effect of Nesting Practice on Pain, Stress Level, and Breastfeeding Success During Intramuscular Injection in Term Newborns Delivered by Cesarean Section

This randomized controlled trial aims to evaluate the effect of nesting during the first intramuscular injection on pain, stress level, physiological parameters, settling time, and breastfeeding success in healthy term newborns delivered by cesarean section. A total of 112 newborns will be randomly assigned in a 1:1 ratio to either a nesting intervention group or a routine care control group. Newborns in the intervention group will receive nesting until the first intramuscular injection, whereas those in the control group will receive routine neonatal care. Pain, stress level, physiological parameters, settling time, and breastfeeding success will be evaluated using validated assessment tools. The findings are expected to provide evidence regarding the effectiveness of nesting as a simple, safe, and non-pharmacological intervention for reducing procedural pain and stress in newborns while supporting breastfeeding success.

Detaljeret beskrivelse

Painful procedures performed during the first hours after birth, particularly intramuscular vitamin K and hepatitis B injections, are associated with significant pain and stress responses in newborns. Although several non-pharmacological interventions have been recommended to minimize procedural pain, evidence regarding the effectiveness of nesting in healthy term newborns delivered by cesarean section remains limited.

This study is designed as a prospective, single-center, parallel-group, randomized controlled trial. The study will be conducted in the newborn observation room of the Delivery Unit at Kocaeli Darıca Farabi Training and Research Hospital. Healthy term newborns (37-42 weeks of gestation) delivered by cesarean section will be enrolled after written informed parental consent is obtained. A total of 112 newborns will be randomly allocated in a 1:1 ratio to either the nesting intervention group or the routine care control group using Random Allocation Software.

Newborns assigned to the intervention group will be placed in a sterile cotton nesting position until the first intramuscular injection. Routine intramuscular administration of vitamin K and hepatitis B vaccine will be performed according to standard neonatal care. The control group will receive routine neonatal care without nesting. No additional invasive procedures will be performed for research purposes.

Pain, stress level, heart rate, respiratory rate, oxygen saturation, and settling time will be assessed before, during, and one minute after the injection. Breastfeeding success will be evaluated at the first breastfeeding after mother-infant reunion, at one hour after breastfeeding, and before hospital discharge using validated assessment tools. Outcome assessment will be performed by an independent assessor who is blinded to group allocation.

The primary objective of this study is to determine whether nesting reduces procedural pain and stress while improving physiological stability and breastfeeding success in term newborns delivered by cesarean section. The results are expected to contribute to evidence-based neonatal care by supporting the implementation of developmental, non-pharmacological interventions during routine newborn procedures.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Nesting Group
Term newborns delivered by cesarean section will receive the nesting intervention before and during routine intramuscular injection. Pain, stress level, and breastfeeding success will be assessed using validated outcome measures.
Nesting is a non-pharmacological positioning intervention in which the newborn is placed in a flexed, midline posture using rolled towels or positioning supports to provide containment before and during intramuscular injection. The intervention aims to reduce procedural pain and stress and improve breastfeeding success.
Ingen indgriben: Standard Care Group
Term newborns delivered by cesarean section will receive routine care during intramuscular injection without the nesting intervention. Pain, stress level, and breastfeeding success will be assessed using the same outcome measures.

Tidsramme
Heart Rate
Tidsramme: Immediately before intramuscular injection, during intramuscular injection, and 1 minute after intramuscular injection.
Heart rate will be measured in beats per minute (bpm) to evaluate the newborn's physiological response to intramuscular injection. Higher heart rate values indicate a greater physiological response to procedural stress.
Immediately before intramuscular injection, during intramuscular injection, and 1 minute after intramuscular injection.
Respiratory Rate
Tidsramme: Immediately before intramuscular injection, during intramuscular injection, and 1 minute after intramuscular injection.
Respiratory rate will be measured in breaths per minute (breaths/min) to evaluate the newborn's physiological response to intramuscular injection. Higher respiratory rate values indicate a greater physiological response to procedural stress.
Immediately before intramuscular injection, during intramuscular injection, and 1 minute after intramuscular injection.
Peripheral Oxygen Saturation
Tidsramme: Immediately before intramuscular injection, during intramuscular injection, and 1 minute after intramuscular injection.
Peripheral oxygen saturation (SpO₂) will be measured using pulse oximetry and reported as a percentage (%) to evaluate the newborn's physiological response to intramuscular injection. Higher SpO₂ values indicate better oxygenation.
Immediately before intramuscular injection, during intramuscular injection, and 1 minute after intramuscular injection.
Breastfeeding Success
Tidsramme: At the first breastfeeding following mother-newborn reunion, 1 hour after the first breastfeeding, and 48 hours after birth (prior to hospital discharge).
Breastfeeding success will be assessed using the Bristol Breastfeeding Assessment Tool (BBAT). The BBAT consists of four items (positioning, attachment, sucking, and swallowing), each scored from 0 to 2. Total scores range from 0 to 8, with higher scores indicating better breastfeeding effectiveness.
At the first breastfeeding following mother-newborn reunion, 1 hour after the first breastfeeding, and 48 hours after birth (prior to hospital discharge).
