“…The standardized and adequate positioning is capable of improving the respiratory capacity of the patients submitted to it, besides optimizing the physiological stability that consequently favors the improvement of the respiratory pattern capable of reducing RR (15) . In the development of a study (16) , which compared the INFs in normal conditions (dorsal and lateral decubitus) and VD, it was found a significant reduction in RR when INFs were positioned in VD, suggesting a reduction in stress levels with the positioning in appropriate VD.…”

“…Cândia et al [13] measured salivary cortisol levels in preterm newborns subjected to a prone position. Similar results were obtained with regard to a significant reduction in salivary cortisol levels (0.20 versus 0.13 μ g/dL; p = 0.003).…”

“…Similar results were obtained with regard to a significant reduction in salivary cortisol levels (0.20 versus 0.13 μ g/dL; p = 0.003). This shows that positions and techniques that facilitate lower energy consumption, improved sleep quality, and better postural organization promote reductions in the potential harmful effects of hospitalization in the NICU [13]. According to Bates and Hanson [41], these beneficial results can be explained by the physiological effects of water on pain relief, acting at the level of the dorsal horn of the spinal cord by stimulating the major afferent receptors and conveying less painful messages.…”

“…In this context, salivary cortisol measurement is indicated for the neonatal population, as it is a simple, noninvasive, and safe procedure for evaluating the stress threshold of a newborn [11–14]. Cândia et al [13] and Takahashi et al [15] have found that measuring salivary cortisol levels is a useful tool for evaluating the stress response in preterm newborns [13, 15]. However, Maas et al [16] noted that the sensitivity and specificity of salivary cortisol in the detection of suprarenal insufficiency in newborns are low, with values of 0.66 and 0.62, respectively.…”

Background. In the neonatal intensive care unit (NICU) environment, preterm newborns are subject to environmental stress and numerous painful interventions. It is known that hydrokinesiotherapy promotes comfort and reduces stress because of the physiological properties of water. Objective. To evaluate the short-term effects of hydrokinesiotherapy on reducing stress in preterm newborns admitted to the NICU. Materials and Methods. Fifteen preterm newborns underwent salivary cortisol measurement, pain evaluation using the Neonatal Infant Pain Scale (NIPS), and heart rate, respiratory rate, and peripheral oxygen saturation measurements before and after the application of hydrokinesiotherapy. Results. The mean gestational age of the newborns was 34.2 ± 1.66 weeks, and the mean weight was 1823.3 ± 437.4 g. Immediately after application of hydrokinesiotherapy, a significant reduction was observed in salivary cortisol (p = 0.004), heart rate (p = 0.003), and respiratory rate (p = 0.004) and a significant increase was observed in peripheral oxygen saturation (p = 0.002). However, no significant difference was observed in the NIPS score (p > 0.05). Conclusion. In the present study, neonatal hydrotherapy promoted short-term relief from feelings of stress. Neonatal hydrokinesiotherapy may be a therapeutic alternative. However, this therapy needs to be studied in randomized, crossover, and blinded trials. This trial is registered with NCT02707731.

A functional stress-response system is essential for survival at birth, as well as for health and further development. Altered cortisol response and hypothalamic-pituitary-adrenal system function may have both short and long-term effects on health and development throughout life. Cortisol secretion follows a circadian rhythm in adults. Data in the literature concerning basal cortisol levels is scant, with divergent results regarding the timeframe for establishment of cortisol circadian rhythm in children. Nevertheless, cortisol is often studied in stress-related research concerning preterm infants, full-term infants, and infants at high psychosocial risk. This thesis aimed to investigate at what age cortisol circadian rhythm develops in healthy full-term infants, preterm infants, and infants at high psychosocial risk and to identify whether such development is dependent on gestational or postnatal age. A secondary aim was to investigate whether either behavioral regularity or daily life trauma are associated with establishment of cortisol circadian rhythm. The last two interventional studies explored whether a) parental participation in the Hagadal daycare attachment program in one study and b) oral administration of glucose during nasopharyngeal suctioning in the other study influenced development of salivary cortisol circadian rhythm and/or cortisol levels. The effects, if any, of the Hagadal daycare attachment program on caregiver sensitivity to infants were also investigated. The present thesis includes four original studies. Papers I, II, and III describes prospective, longitudinal studies extending over a year, including a survey of the cortisol levels and development of cortisol circadian rhythm in three infant groups. Paper III also included an intervention component addressing the possible effects of the Hagadal daycare attachment program. Paper IV describes a case-control study designed to generate paired baseline-response data concerning the effects of oral glucose administration during nasopharyngeal suctioning as an interventional procedure. Cortisol circadian rhythm in salivary cortisol secretion was similarly established at one month postnatal age in full-term infants and at one month corrected age in preterm infants, reflecting a process dependent on gestational age. This rhythm persisted throughout the first year of life in all infants and consolidated over time in healthy full-term and preterm infants, but not in infants at high psychosocial risk, who displayed higher variability in cortisol levels. The infants in paper IV had not yet reached one month of corrected age and therefore had not yet developed cortisol circadian rhythm at the time of the investigation. No correlation was found between development of cortisol circadian rhythm and either behavioral regularity or reported traumatic life events. This thesis presents data on salivary cortisol levels among three different groups of infants during the first year of life. Cortisol circadian rhythm among infants in study III evolved in respon...
