ObjectiveTo determine respiratory rate (RR), tidal volume (TV) and end-tidal carbon dioxide (EtCO2) values in full-term infants immediately after caesarean section, and to assess whether infants that develop transient tachypnoea of the newborn (TTN) follow the same physiological patterns.Design and patientsA Respironics NM3 Monitor (Philips, Netherlands) continuously measured RR, TV and EtCO2 for 7 min in infants >37 weeks’ gestation following elective caesarean section (ECS). Monitoring was repeated at 2 hours of age for 2 min. Gestation, birth weight, Apgar scores and admissions to neonatal unit were documented.SettingThe operative delivery theatre of Cork University Maternity Hospital, Ireland.ResultsThere were 95 term infants born by ECS included. Median (IQR) gestation was 39 weeks (38.2–39.1) and median (IQR) birth weight 3420 g (3155–3740). Median age at initiation of monitoring was 26.5 s (range: 20–39). Data were analysed for the first 7 min of life. Mean breaths per minute (bpm) increased over the first 7 min of life (44.31–61.62). TV and EtCO2 values were correlated and increased from 1 min until maximum mean values were recorded at 3 min after delivery (5.18 mL/kg–6.44 mL/kg, and 4.32 kPa–5.64 kPa, respectively). Infants admitted to the neonatal unit with TTN had significantly lower RRs from 2 min of age compared with infants not admitted for TTN.ConclusionsTV and EtCO2 values are correlated and increase significantly over the first few minutes following ECS. RR increases gradually from birth, and rates were lower in infants that develop TTN.

Emergency Caesarean

This study was conducted to determine the value of computed tomography [CT] pelvimetry in patients with previous caesarean section. Of 219 pregnant women with one previous caesarean section, 100 had antenatal CT pelvimetry and a control group of 119 women had no CT pelvimetry. In the CT pelvimetry group, 51.0% delivered by caesarean section, 28.0% underwent elective caesarean section for contracted pelvis based on the findings of CT pelvimetry and 23% underwent emergency caesarean section after a trial labour. In the control group, 21.8% underwent emergency caesarean section. The differences in birth weight and Apgar scores between the groups were not statistically significant. CT pelvimetry increased the rate of caesarean delivery, suggesting that CT pelvimetry before a vaginal birth after a previous caesarean delivery is of limited value

BackgroundNon-invasive cardiac output monitoring (NICOM) provides continuous estimation of cardiac output. This has potential for use in the delivery suite in the management of acutely depressed term infants. This study aims to measure cardiac output in term infants at delivery and in the first hours of life.MethodsParents of term infants due to be born by elective caesarean section or vaginal delivery at Cork University Maternity Hospital, Ireland were approached in the antenatal period to participate. Cardiac output was measured using a CHEETAH NICOM device, which uses electrical bioreactance technology, at birth and at 2 hours of life.ResultsForty-nine newborns were included. The median gestational age was 39 (IQR: 39–40) weeks and the median birth weight was 3.50 (IQR: 3.14–3.91) kg. Cardiac output measurements were obtained at a median of 8 (IQR: 5–12) min of life. The mean (SD) cardiac output was 101 (24) mL/kg/min in the delivery room and 89 (22) mL/kg/min at 2 hours of life. There was a statistically significant decrease in cardiac output from birth to 2 hours of life (difference in mean (95% CI): 13.5 (9.2 to 17.9) mL/kg/min, p<0.001, n=47). There were no adverse effects associated with NICOM.DiscussionThis technique is feasible and safe in the delivery room. Mean cardiac output measures using NICOM are lower than those found in studies which used echocardiography to determine cardiac output at birth.

AbstractBackgroundThe amino acids glutamine plus glutamate, phenylalanine and tyrosine are implicated in neurotransmission. We aimed to evaluate these amino acid blood concentrations in full-term breastfed infants with different birth weight (BW) perinatally.MethodsBreastfed full-term infants (n = 6000, males 3000, females 3000) BW 2000–4000 g were divided into four equal groups. Both males and females Groups A, 2000–2500 g, B 2500–3000 g, C 3000–3500 g, D 3500–4000 g. Blood samples on Guthrie cards, were taken on the 3rd day of life and quantified via a liquid chromatography tandem mass spectrometry (LC-MS/MS) method.ResultsGlutamine plus glutamate mean values were found to be statistically significantly different between males vs. females in all the studied groups. The highest values were determined in both males and females in group D. Statistically significantly higher values of phenylalanine appeared in group D vs. other groups. Tyrosine mean values were calculated to be statistically significantly different in both sexes in group A compared to other groups.ConclusionsDifferences of glutamine plus glutamate, phenylalanine and tyrosine levels among full-term newborns with different BW are presented for the first time in the literature. Newborns with BW 3000–4000 g are benefited by having higher concentrations of the mentioned neurotransmission related amino acids. Neonatal screening reference values for these amino acids in relation to BW could be established, not only for preterm and low BW infants but also for full-term newborns with BW >3000 g.
