“…This change was inconsistent during the middle time period, matching an earlier report by Berger et al 7 on data between 2005 and 2009. The GA strata and place of death are consistent with the trend to resuscitate infants born ≥24 weeks GA and appear to be in accordance with the Swiss guidelines 9.…”

“…Although survival rates for premature infants (,32 weeks' gestation) have improved dramatically in the past 10 years, 1 parents, particularly mothers, continue to have very high rates of psychological distress beyond those observed in parents of full-term infants. 2 In addition to high rates of depression, [3][4][5] researchers have identified acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) as features of parental psychological reactions.…”

Prevention of Traumatic Stress in Mothers of Preterms: 6-Month Outcomes

et al. 2014

View full text Add to dashboard Cite

WHAT'S KNOWN ON THIS SUBJECT: Interventions based on principles of trauma-focused cognitive behavior therapy have been shown to reduce symptoms of trauma and depression in mothers of premature infants. It is not known whether these benefits are sustained at long-term follow-up. WHAT THIS STUDY ADDS:A brief, cost-effective 6-session manualized intervention for parents of infants in the NICU was effective in reducing symptoms of parental trauma, anxiety, and depression at 6-month follow-up. There were no added benefits from a 9-session version of the treatment.abstract OBJECTIVE: Symptoms of posttraumatic stress disorder are a wellrecognized phenomenon in mothers of preterm infants, with implications for maternal health and infant outcomes. This randomized controlled trial evaluated 6-month outcomes from a skills-based intervention developed to reduce symptoms of posttraumatic stress disorder, anxiety, and depression. METHODS:One hundred five mothers of preterm infants were randomly assigned to (1) a 6-or 9-session intervention based on principles of trauma-focused cognitive behavior therapy with infant redefinition or (2) a 1-session active comparison intervention based on education about the NICU and parenting of the premature infant. Outcome measures included the Davidson Trauma Scale, the Beck Depression Inventory II, and the Beck Anxiety Inventory. Participants were assessed at baseline, 4 to 5 weeks after birth, and 6 months after the birth of the infant.RESULTS: At the 6-month assessment, the differences between the intervention and comparison condition were all significant and sizable and became more pronounced when compared with the 4-to 5-week outcomes: Davidson Trauma Scale (Cohen' s d = 20.74, P , .001), Beck Anxiety Inventory (Cohen' s d = 20.627, P = .001), Beck Depression Inventory II (Cohen' s d = 20.638, P = .002). However, there were no differences in the effect sizes between the 6-and 9-session interventions.CONCLUSIONS: A brief 6-session intervention based on principles of trauma-focused cognitive behavior therapy was effective at reducing symptoms of trauma, anxiety, and depression in mothers of preterm infants. Mothers showed increased benefits at the 6-month follow-up, suggesting that they continue to make use of techniques acquired during the intervention phase. Pediatrics 2014;134:e481-e488 AUTHORS:

“…Our overall survival rate of 57.5% (50/87) for that gestational age range is within the survival range of 36-63% described in the current literature (including survival to discharge) [2,3,[13][14][15][16][17] . We only looked at short-term survival at 6 weeks postnatally; however, long-term survival has to be considered as well.…”

Introduction: To determine the accuracy of estimated fetal weight (EFW) at the limit of viability in a delivery room setting and its impact on the prediction of neonatal outcome. Material and Methods: In this retrospective, single-center cohort study we included patients with preterm birth between 23⁰/₇ and 26⁰/₇ weeks of gestation. Neonates were divided into 3 groups according to birth weight at delivery (accuracy index 90-110%, <90%, >110%). Neonatal outcome for each group was categorized into survival with and without impairment and death, with a follow-up period of 6 weeks. Results: Eighty-seven newborns were included, with 62.1% accurately estimated. Gestational age at birth, fetal sex, maternal body mass index, and time interval between birth and ultrasound affected the accuracy of EFW. Chances of survival were significantly higher in the underestimated group for birth weight at delivery compared with estimated weight (p < 0.001), with risk of death being significantly lower (p < 0.001). The reverse was true for overestimated infants, for both risk of death and chances of survival. At 6 weeks' follow-up, there were significantly more deceased overestimated infants (p = 0.041). Discussion: Our study shows that inaccuracy of EFW at the limit of viability occurs frequently in a delivery room setting with a potential impact on neonatal outcome.
