### Newborn Transition The transition from intrauterine to extrauterine life that occurs at the time of birth requires timely anatomic and physiologic adjustments to achieve the conversion from placental gas exchange to pulmonary respiration. This transition is brought about by initiation of air breathing and cessation of the placental circulation. Air breathing initiates marked relaxation of pulmonary vascular resistance, with considerable increase in pulmonary blood flow and increased return of now-well-oxygenated blood to the left atrium and left ventricle, as well as increased left ventricular output. Removal of the low-resistance placental circuit will increase systemic vascular resistance and blood pressure and reduce right-to-left shunting across the ductus arteriosus. The systemic organs must equally and quickly adjust to the dramatic increase in blood pressure and oxygen exposure. Similarly, intrauterine thermostability must be replaced by neonatal thermoregulation with its inherent increase in oxygen consumption. Approximately 85% of babies born at term will initiate spontaneous respirations within 10 to 30 seconds of birth, an additional 10% will respond during drying and stimulation, approximately 3% will initiate respirations after positive-pressure ventilation (PPV), 2% will be intubated to support respiratory function, and 0.1% will require chest compressions and/or epinephrine to achieve this transition.1–3 Although the vast majority of newborn infants do not require intervention to make these transitional changes, the large number of births worldwide means that many infants require some assistance to achieve cardiorespiratory stability each year. Newly born infants who are breathing or crying and have good tone immediately after birth must be dried and kept warm so as to avoid hypothermia. These actions can be provided with the baby lying on the mother’s chest and should not require separation of mother and baby. This does not preclude the need for clinical assessment of the baby. …

The International Liaison Committee on Resuscitation (ILCOR) consensus on science with treatment recommendations for pediatric and neonatal patients: Neonatal resuscitation

APPROXIMATELY 10% OF newborns require some assistance to begin breathing at birth, and about 1% require extensive resuscitation. Although the vast majority of newborn infants do not require intervention to make the transition from intrauterine to extrauterine life, the large number of births worldwide means that many infants require some resuscitation. Newborn infants who are born at term, had clear amniotic fluid, and are breathing or crying and have good tone must be dried and kept warm but do not require resuscitation. All others need to be assessed for the need to receive 1 or more of the following actions in sequence:

Gravidez na adolescência: perfil sócio-demográfico e comportamental de uma população da periferia de São Paulo, Brasil

To identify the socio-demographic behavioral profile of low-income pregnant teenagers, 1,000 adolescents admitted to a Brazilian public maternity hospital from July 24, 2001, to November 27, 2002, were interviewed. Socio-demographic and behavioral variables were assessed through a questionnaire. Over the 492 days of the study, 24.3% of admissions were adolescents (930 for childbirth and 70 for miscarriage). Mean maternal age was 17 years. Most teenagers (72.9%) lived near the hospital. 930 (93%) belonged to socioeconomic classes C, D, and E. School dropout was identified in 67.3% of the total. 80.1% of the subjects were giving birth for the first time. 81.2% had not planned the pregnancy, and 23.8% had been using some contraceptive method. 67.4% had vaginal deliveries. Some 13.3% of the newborns were premature and 15.9% had low birth weight. 17.3% of these adolescent mothers reported smoking during pregnancy, with 2.8% reporting alcohol and 1.7% illicit drugs. Teenage pregnancy is a complex phenomenon associated with various economic, educational, and behavioral factors. The study provides importance references for public policies to prevent teenage pregnancy.

Differences in pain expression between male and female newborn infants

Abstract The study of neonatal gender differences in pain expression is important since neonatal pain behavior occurs prior to any learned reaction pattern. The objective of this study was to verify the presence of gender differences in pain expression in preterm and term newborn infants. Sixty‐five consecutive neonates (37 female and 28 male infants) with gestational age between 28 and 42 weeks and with 25–120 h of life were studied. Healthy term neonates required a capillary puncture for PKU screening and clinically stable premature infants needed a capillary puncture for glucose dosage. The Neonatal Facial Coding System (NFCS) and the Neonatal Infant Pain Scale (NIPS) were evaluated at bedside prior to the puncture, when patients were at rest, during foot heating; during capillary puncture; and at 1, 3, and 5 min after heel lancing. Results were analyzed by repeated‐measures ANOVA followed by the Multiple Comparison Method of Bonferroni. A significant difference among the mean NFCS scores during the six study periods was noted for the whole group of neonates (P<0.000001). Also, a significant interaction between the NFCS score profile in female and male neonates at the different study periods was observed (P=0.025). Regarding NIPS, ANOVA showed only a significant difference among the mean NIPS scores during the six study periods for the whole group of neonates (P<0.000001). No significant interactions between gestational age and time, nor between gestational age and gender were noted, for both NFCS and NIPS. In conclusion, recently born female neonates of all gestational ages expressed more facial features of pain than male infants, during the capillary puncture and 1 min afterwards. Maybe differences in pain processing and/or pain expression among genders may explain this finding.

Physiological, hormonal, and behavioral responses to a single fentanyl dose in intubated and ventilated preterm neonates

OBJECTIVE To study the responses of ventilated preterm neonates to a single dose of opioid. STUDY DESIGN In a randomized, double-blind, controlled trial, 22 mechanically ventilated preterm infants (< or = 32 weeks) were observed before medication and at 30 and 60 minutes after administration of fentanyl (3 micrograms/kg) or placebo. Heart rate, blood pressure, arterial blood gases, ventilator settings, and behavioral measures (Neonatal Facial Coding System and Modified Postoperative Comfort Score) were recorded during each period. Blood cortisol, growth hormone, glucose, and lactate were measured before and at 60 minutes after analgesia. Behavioral measures were assessed at the bedside and from video films recorded during each observation period. RESULTS Patients presented high basal levels of cortisol, growth hormone, and lactate. Behavioral scales indicated the presence of pain before any medication. In the fentanyl group, the maximum and minimum heart rate decreased and growth hormone level increased after analgesia. At the video analysis of behavioral measures, postoperative comfort score increased and neonatal facial coding system score decreased in the fentanyl group. CONCLUSION Single doses of fentanyl analgesia can reduce the physiologic/behavioral measures of pain and stress associated with mechanical ventilation in preterm infants.

The impact of maternal experience of violence and common mental disorders on neonatal outcomes: a survey of adolescent mothers in Sao Paulo, Brazil

BackgroundBoth violence and depression during pregnancy have been linked to adverse neonatal outcomes, particularly low birth weight. The aim of this study was to investigate the independent and interactive effects of these maternal exposures upon neonatal outcomes among pregnant adolescents in a disadvantaged population from Sao Paulo, Brazil.Methods930 consecutive pregnant teenagers, admitted for delivery were recruited. Violence was assessed using the Californian Perinatal Assessment. Mental illness was measured using the Composite International Diagnostic Interview (CIDI). Apgar scores of newborns were estimated and their weight measured.Results21.9% of mothers reported lifetime violence (2% during pregnancy) and 24.3% had a common mental disorder in the past 12 months. The exposures were correlated and each was associated with low education. Lifetime violence was strongly associated with Common Mental Disorders. Violence during pregnancy (PR = 2.59(1.05–6.40) and threat of physical violence (PR = 1.86(1.03–3.35) and any common mental disorders (PR = 2.09 (1.21–3.63) (as well as depression, anxiety and PTSD separately) were independently associated with low birth weight.ConclusionEfforts to improve neonatal outcomes in low income countries may be neglecting two important independent, but correlated risk factors: maternal experience of violence and common mental disorder.
