“…[7][8][9][10][11][21][22][23][24] Levels of circulating catecholamines are higher in newborns delivered vaginally than in newborns delivered by cesarean section, possibly due to the stimulation of catecholamine release by the stress of labor. 25 Catecholamine levels are lower in infants with TTN than in infants without TTN. 26 In a sheep model, infusion of epinephrine, a catecholamine hormone, decreased secretion and promoted the absorption of fetal lung fluid.…”

Objective: Infants with transient tachypnea of the newborn (TTN) have relatively low levels of epinephrine, which is known to mediate fetal lung fluid absorption. Providing exogenous epinephrine could be a valuable diagnostic and therapeutic intervention for this common condition. Our primary objective was to determine if inhaled racemic epinephrine is safe for the treatment of TTN. Our secondary objective was to determine its efficacy.Study Design: We conducted a randomized, blinded, placebo-controlled pilot trial. Inhaled racemic epinephrine or placebo was administered to 20 newborns with TTN. Physiologic variables of cardiopulmonary function were measured during and after treatment.Result: No infant in either the treatment or control arm experienced an adverse event, including tachycardia or hypertension. We did not detect a difference between the two groups regarding rate of resolution of tachypnea. Conclusion:We did not observe any adverse effects of inhaled racemic epinephrine when administered for the treatment of TTN. Larger studies are necessary to determine efficacy.

“…This response appears to be linked to a reduced postpartum surge in thyroid hormones (Symonds et al 1994c) and lower plasma concentrations of catecholamines (Irestedt et al 1982). An additional factor which influences metabolic adaptation in lambs delivered by caesarean section is ambient temperature, which may induce differential effects on catecholamine and thyroid status Symonds et al 1994~).…”

“…Concentrações mais elevadas de epinefrina, norepinefrina e dopamina foram encontradas no plasma umbilical de neonatos nascidos por via vaginal comparativamente aos nascidos por cesárea [6][7][8][9][10] . Concentrações mais elevadas de cortisol e TSH também foram encontradas no funículo umbilical dos nascidos de parto vaginal [11][12][13][14][15] .…”

Artigo submetido em 28.05.03, aceito em 05.11.03. AbstractObjective: To investigate the association between type of delivery and immunoglobulin concentration in maternal colostrum. Methods:We studied 82 women who were giving birth. Age was between 21 and 41 years, gestational age was 37 or more weeks and parity up to IV pregnancies. The women were in good nutritional condition and did not have any pregnancy or puerperium-associated diseases. The following aspects were also considered as inclusion criteria for the newborn: weight > 2,500 g, Apgar score > 7 in the first minute and exclusive breastfeeding until discharge from the nursery. The women were divided into three groups: A -vaginal delivery, Bcaesarean section with labor and C -elective caesarean section. Colostrum was collected manually between 48 and 72h after delivery. Immunoglobulins were dosed using the ELISA technique.Results: There were no differences between the three groups in terms of time of colostrum collection. The shorter the time of colostrum collection, the greater the concentration of immunoglobulin A. Primiparous women had higher concentrations of IgA and IgM in maternal colostrum than did multiparous women. The group submitted to caesarean section with labor had higher concentrations of IgA in maternal colostrum than did the normal delivery group. IgM and IgG concentrations in colostrum were not influenced by type of delivery. Conclusion:The occurrence of labor together with surgical stress induce higher IgA concentrations in the colostrum of women submitted to caesarean section with labor.
