Parental views on prospective consent: Experience from a pilot randomised trial recruiting extremely preterm infants during the perinatal period.

AIM: To explore parental perceptions of the consenting process and understanding of the study in a pilot randomised controlled trial wherein extremely premature infants (<29 weeks' gestation) were recruited either antenatally or by 4 h of life. METHODS: We prospectively surveyed parents who had consented, declined consent or were eligible infants in the Positioning Preterm Infants for Neuroprotection study, a low-risk intervention study in the first 72 h of life. Structured interview questions explored the process and acceptability of the consenting approach by the parents and their knowledge of the study. Additional comments made by the parents were transcribed verbatim. RESULTS: Sixty-two parents participated in the surveys; of those, 41 had provided their consent, 8 declined consent and 13 were parents of missed eligible infants. Overall, most parents reported they understood the study well before providing their consent and approaching them for consenting did not create a burden for them. A verbal explanation of the study by the study team, especially by the medical practitioners, was viewed as beneficial. Where consent was obtained in the birthing unit (imminent births and within 4 h of birthing), it was suggested that the 4-h period for obtaining post-natal consent may be too short. A deferred consent with a follow-up opportunity for obtaining informed consent could be a suitable alternative. CONCLUSION: Parents found the consenting process acceptable and indicated they had sufficient understanding of the study to provide an informed consent. Deferred consent should be explored for future, low-risk intervention studies as an alternative to prospective consent where extremely preterm infants need to be recruited in the immediate neonatal period.

Thermoregulation and golden hour practices in extremely preterm infants: an international survey.

BACKGROUND: Are thermoregulation and golden hour practices in extremely preterm (EP) infants comparable across the world? This study aims to describe these practices for EP infants based on the neonatal intensive care unit's (NICUs) geographic region, country's income status and the lowest gestational age (GA) of infants resuscitated. METHODS: The Director of each NICU was requested to complete the e-questionnaire between February 2019 and August 2021. RESULTS: We received 848 responses, from all geographic regions and resource settings. Variations in most thermoregulation and golden hour practices were observed. Using a polyethylene plastic wrap, commencing humidity within 60 min of admission, and having local protocols were the most consistent practices (>75%). The odds for the following practices differed in NICUs resuscitating infants from 22 to 23 weeks GA compared to those resuscitating from 24 to 25 weeks: respiratory support during resuscitation and transport, use of polyethylene plastic wrap and servo-control mode, commencing ambient humidity >80% and presence of local protocols. CONCLUSION: Evidence-based practices on thermoregulation and golden hour stabilisation differed based on the unit's region, country's income status and the lowest GA of infants resuscitated. Future efforts should address reducing variation in practice and aligning practices with international guidelines. IMPACT: A wide variation in thermoregulation and golden hour practices exists depending on the income status, geographic region and lowest gestation age of infants resuscitated. Using a polyethylene plastic wrap, commencing humidity within 60 min of admission and having local protocols were the most consistent practices. This study provides a comprehensive description of thermoregulation and golden hour practices to allow a global comparison in the delivery of best evidence-based practice. The findings of this survey highlight a need for reducing variation in practice and aligning practices with international guidelines for a comparable health care delivery.

Skincare practices in extremely premature infants: A survey of tertiary neonatal intensive care units from Australia and New Zealand.

AIM: To investigate skincare practices in the first 2 weeks of life in extremely premature infants across tertiary neonatal intensive care units (NICUs). METHODS: A web-based secure survey invite was emailed to the medical directors of tertiary NICUs. The survey included questions on various aspects of skincare practices in the first 2 weeks of life in extremely premature infants (born before 28 weeks gestation). The person most familiar with local skincare practices was asked to complete the survey and only one response per unit was requested. We performed a descriptive analysis. RESULTS: We received responses from 30 out of 32 NICUs (response rate 93%). Twenty-five NICUs (89%) reported offering resuscitation and intensive care to infants born at ≥23 weeks gestation. All NICUs reported occurrences of skin breakdown, including medical adhesive-related skin injury (30%), abrasion/friction-associated skin injury (46%), perineal skin breakdown (55%), pressure site injury (47%) and diaper dermatitis (60%). A high level of consensus (≥75%) was observed for certain practices, such as the use of polyethylene occlusive plastic wraps at birth and aqueous chlorhexidine solution for sterile procedures, but a low level of consensus (<25%) was observed for many other practices, including the skin risk assessment tool used. CONCLUSIONS: Skin injuries in extremely premature infants are common and skincare practices vary considerably amongst NICUs. Clinical practice improvement projects and further clinical research will help improve consistency amongst NICUs. Further research is needed to assist the development of evidence-based guidelines and benchmarking for skincare practices in these vulnerable infants.

Mask leak increases and minute ventilation decreases when chest compressions are added to bag ventilation in a neonatal manikin model.

AIM: To determine changes in respiratory mechanics when chest compressions are added to mask ventilation, as recommended by the International Liaison Committee on Resuscitation (ILCOR) guidelines for newborn infants. METHODS: Using a Laerdal Advanced Life Support leak-free baby manikin and a 240-mL self-inflating bag, 58 neonatal staff members were randomly paired to provide mask ventilation, followed by mask ventilation with chest compressions with a 1:3 ratio, for two minutes each. A Florian respiratory function monitor was used to measure respiratory mechanics, including mask leak. RESULTS: The addition of chest compressions to mask ventilation led to a significant reduction in inflation rate, from 63.9 to 32.9 breaths per minute (p < 0.0001), mean airway pressure reduced from 7.6 to 4.9 cm H2 O (p < 0.001), minute ventilation reduced from 770 to 451 mL/kg/min (p < 0.0001), and there was a significant increase in paired mask leak of 6.8% (p < 0.0001). CONCLUSION: Adding chest compressions to mask ventilation, in accordance with the ILCOR guidelines, in a manikin model is associated with a significant reduction in delivered ventilation and increase in mask leak. If similar findings occur in human infants needing an escalation in resuscitation, there is a potential risk of either delay in recovery or inadequate response to resuscitation.

Global variation in skin injures and skincare practices in extremely preterm infants.

BACKGROUND: Globally, are skincare practices and skin injuries in extremely preterm infants comparable? This study describes skin injuries, variation in skincare practices and investigates any association between them. METHODS: A web-based survey was conducted between February 2019 and August 2021. Quantifying skin injuries and describing skincare practices in extremely preterm infants were the main outcomes. The association between skin injuries and skincare practices was established using binary multivariable logistic regression adjusted for regions. RESULTS: Responses from 848 neonatal intensive care units, representing all geographic regions and income status groups were received. Diaper dermatitis (331/840, 39%) and medical adhesive-related skin injuries (319/838, 38%) were the most common injuries. Following a local skincare guideline reduced skin injuries [medical adhesive-related injuries: adjusted odds ratios (aOR) = 0.63, 95% confidence interval (CI) = 0.45-0.88; perineal injuries: aOR = 0.66, 95% CI = 0.45-0.96; local skin infections: OR = 0.41, 95% CI = 0.26-0.65; chemical burns: OR = 0.46, 95% CI = 0.26-0.83; thermal burns: OR = 0.51, 95% CI = 0.27-0.96]. Performing skin assessments at least every four hours reduced skin injuries (abrasion: aOR = 0.48, 95% CI = 0.33-0.67; pressure: aOR = 0.51, 95% CI = 0.34-0.78; diaper dermatitis: aOR = 0.71, 95% CI = 0.51-0.99; perineal: aOR = 0.52, 95% CI = 0.36-0.75). Regional and resource settings-based variations in skin injuries and skincare practices were observed. CONCLUSIONS: Skin injuries were common in extremely preterm infants. Consistency in practice and improved surveillance appears to reduce the occurrence of these injuries. Better evidence regarding optimal practices is needed to reduce skin injuries and minimize practice variations.

Efficacy of oral sucrose in infants of methadone-maintained mothers.

BACKGROUND: One report indicated that taste-induced analgesia was sub-optimal in methadone-exposed (ME) infants. OBJECTIVES: The purpose of this work was to compare the effects of oral sucrose in infants born to methadone-maintained mothers with control infants. METHODS: The aim was to compare the effects of an oral sucrose solution in infants scheduled to have a heel lance procedure for routine newborn screening. Infants received 0.05 ml (one drop) of a 24% sucrose solution by mouth 2 min before a heel lance procedure, then a further 0.05 ml of sucrose at the time of the heel lance; this was repeated every 1-2 min until 30 s after the completion of the procedure. The primary outcome measure was pain. We assessed pain using the Premature Infant Pain Profile (PIPP), which is a validated composite pain assessment tool. RESULTS: PIPP scores were similar in both infant groups. Median PIPP scores of the ME infant group versus the control infant group were 2.0 (interquartile range (IQR) 0-7) versus 2.0 (IQR 0-9) at the time of the heel lance (p = 0.99) and 2.0 (IQR 0-4) versus 1.0 (IQR 0-4) 30 s after the completion of the heel lance procedure (p = 0.28). CONCLUSIONS: This study found no differences in the pain responses of ME infants and non-exposed infants when given sucrose during heel lance procedures.
