RESUMEN

BACKGROUND: Preterm infants with intraventricular hemorrhage (IVH) are at a risk of developing neurodevelopmental disabilities. Few studies have examined the effects of oxygen saturation (SpO2) changes and intubation procedures on the risk of IVH. OBJECTIVES: We examined the effects of intubation and the rates of three thresholds of hypoxemia on the occurrence of IVH in preterm infants during their first week in the neonatal intensive care unit (NICU). METHODS: In this prospective observational cohort study, preterm infants with a gestational age (GA) of <37 weeks were included from two Level III NICUs in Taiwan. Continuous electrocardiography was used to monitor SpO2 changes, and cranial ultrasonography was used to monitor IVH. Thresholds of hypoxemia (SpO2 levels of <80 %, <85 %, and <90 %) were screened by digitally sampling data at 10-s intervals. Generalized estimating equations were used with logistic regression to analyze the effects of intubation and the rates of the three thresholds of hypoxemia on the risk of IVH during the first week after birth. RESULTS: In all preterm infants (N = 73), the mean GA was 31.55 weeks, and the mean birth weight was 1508.86 g. Intubation within 3 days of birth, duration of mechanical ventilation and oxygen use, hypoxemia rate, and maternal use of magnesium sulfate before and during delivery were significantly associated with IVH. A multivariate analysis revealed that intubation was a key factor associated with the occurrence of IVH across different thresholds of hypoxemia (p = 0.004). CONCLUSIONS: Although the rate of hypoxemia, duration of mechanical ventilation and oxygen use, and maternal use of magnesium sulfate were significantly associated with IVH, intubation within 3 days of birth was the key factor responsible for increased IVH risk.

RESUMEN

PURPOSE: Even routine procedures can cause pain and stress, and can be harmful to the fast-growing brain of preterm infants. Mitigating pain and stress with sucrose and analgesics has side effects; thus, an alternate choice is the use of natural breast milk and infants' sensory capabilities. Therefore, this study examined the effects of different integrations of sensory experiences-mother's breast milk odor and taste (BM-OT), heartbeat sounds (HBs), and non-nutritive sucking (NNS)-on preterm infant's behavioral stress during venipuncture. DESIGN: This study was a prospective, randomized controlled trial. METHODS: Infants born preterm (<37 weeks' gestational age) were enrolled in the study through convenience sampling, and randomly assigned to the following conditions: (condition 1) routine care (n = 36); (condition 2) BM-OT (n = 33); (condition 3) BM-OT + HBs (n = 33); or (condition 4) BM-OT + HBs + NNS (n = 36). Crying duration from puncture to recovery period was recorded using a voice recorder. Facial actions and body movements were measured using an infant behavioral coding scheme and transformed into frequencies during seven stages: baseline (stage 0), disinfecting (stage 1), venipuncture (stage 2), and the recovery period for 10 minutes (stages 3-6). FINDINGS: Data were analyzed for 138 preterm infants. The corresponding median times to stop crying for conditions 1, 2, 3, and 4 were 137, 79, 81, and 39 s, respectively; the instantaneous occurrence rates of stopping crying for conditions 2, 3, and 4 were 1.469, 1.574, and 2.996 times greater than for condition 1, respectively. Infants receiving conditions 3 and 4 had significantly fewer occurrences of facial actions (stage 6 and stages 4-6, respectively) and body movements (stages 3-6 for both); however, there were no significant reductions in stress behaviors for condition 2 (BM-OT). CONCLUSIONS: The combination of BM-OT, HBs, and NNS could be provided to preterm infants as interventions to prevent and reduce behavioral stress, and facilitate pain recovery during venipuncture procedures. CLINICAL RELEVANCE: Clinicians should be educated about how to recognize preterm infants' behavioral stress, and to incorporate different sensory combinations of respective mothers' BM, HBs, and NNS into painful procedures to help preterm infants recover from distress.

RESUMEN

BACKGROUND: Preterm infant pain can be relieved by combining non-nutritive sucking (sucking), oral sucrose, and facilitated tucking (tucking), but the pain-relief effects of oral expressed breast milk (breast milk) are ambiguous. AIMS: We compared the effects of combined sucking+ breast milk, sucking+breast milk+tucking, and routine care on preterm infant pain during and after heel-stick procedures. DESIGN: A prospective, randomized controlled trial. SETTINGS: Level III neonatal intensive care unit and a neonatal unit at a medical center in Taipei. PARTICIPANTS/SUBJECTS: Preterm infants (N=109, gestational age 29-37 weeks, stable disease condition) needing procedural heel sticks were recruited by convenience sampling and randomly assigned to three treatment conditions: routine care, sucking+ breast milk, and sucking+breast milk+ tucking. METHODS: Pain was measured by watching video recordings of infants undergoing heel-stick procedures and scoring pain at 1-min intervals with the Premature Infant Pain Profile. Data were collected over eight phases: baseline (phase 1, 10min without stimuli before heel stick), during heel stick (phases 2 and 3), and a 10-min recovery (phases 4-8). RESULTS: For infants receiving sucking+ breast milk, pain-score changes from baseline across phases 2-8 were 2.634, 4.303, 2.812, 2.271, 1.465, 0.704, and 1.452 units lower than corresponding pain-score changes of infants receiving routine care (all p-values <0.05 except for phases 6 and 7). Similarly, for infants receiving sucking +breast milk+ tucking, pain-score changes from baseline were 2.652, 3.644, 1.686, 1.770, 1.409, 1.165, and 2.210 units lower than corresponding pain-score changes in infants receiving routine care across phases 2-8 (all p-values <0.05 except for phase 4). After receiving sucking +breast milk +tucking and sucking +breast milk, infants' risk of mild pain (pain score ≥6) significantly decreased 67.0% and 70.1%, respectively, compared to infants receiving routine care. After receiving sucking +breast milk +tucking and sucking +breast milk, infants' risk of moderate-to-severe pain (pain score ≥12) decreased 87.4% and 95.7%, respectively, compared to infants receiving routine care. CONCLUSION: The combined use of sucking+breast milk +tucking and sucking+breast milk effectively reduced preterm infants' mild pain and moderate-to-severe pain during heel-stick procedures. Adding facilitated tucking helped infants recover from pain across eight phases of heel-stick procedures. Our findings advance knowledge on the effects of combining expressed breast milk, sucking, and tucking on preterm infants' procedural pain.
