Background. Nowadays there is no consensus on the tactics and optimal protocol for Continuous Positive Airway Pressure (СРАР) at transient tachypnea of newborns (TTN) in delivery room. Objective. The aim of the study is to examine the efficacy and safety of standardized protocol of CPAP therapy for newborns with TTN in delivery room. Methods. The clinical study (implementation of standardized CPAP protocol) included full-term infants (gestational age — 37–41 weeks) with diagnosed TTN and CPAP therapy during first 60 minutes of life. Similar inclusion criteria were applied for the historical control group (born within previous year for whom CPAP was implemented according to “usual” protocol). Initiation of mononasal CPAP in main group was carried out when respiratory disorders were assessed according to Downes scale ≥ 3 points with control points at 20–40–60 minutes via the same scale, in control group at ≥ 4 points — for all cases, and according to the doctor's decision at 1–3 points. Mean airway pressure was maintained at 8 and 5–10 cm H2O, CPAP duration was 20–60 and 5–30 min, respectively. The major endpoints: the frequency of patient transfer from delivery room to intensive care unit or hospitalization to the neonatal pathology department, as well as total period of hospitalization. Moreover, frequency of invasive manipulations (intravenous catheterization, parenteral feeding), antibacterial therapy, cerebral injuries (cerebral ischemia, intracerebral hemorrhage), nasal passages injuries, pneumothorax (in the first 24 hours of life) were recorded during the entire hospitalization period. Results. 140 newborns with TTN were included in the clinical study, 30 were excluded from the study, specifically 13 due to violation of the CPAP protocol. The historical control group included 165 newborns. This groups were comparable for most baseline (before the start of CPAP) indicators except for maternal COVID-19 frequency during pregnancy and twin newborns frequency. This groups were comparable for most baseline (before the start of CPAP) indicators except for the frequency of maternal COVID-19 cases during pregnancy and the frequency of twin newborns. Hospitalization rate in intensive care units (18.2 versus 70.3%; p < 0.001) and neonatal pathology departments (31.8 versus 80.0%; p < 0.001), as well as total period of hospitalization (3 versus 10 days; p < 0.001) were lower in the standardized CPAP therapy group. Lower frequency of invasive manipulations, antibacterial therapy, and cerebral ischemia was recorded in this group. The safety of СРАР administration in delivery room was confirmed by the absence of nasal passages injuries in both groups, as well as comparable frequency of pneumothorax. Conclusion. The use of standardized CPAP protocol in delivery room for full-term newborns with TTN had higher rate of favorable hospitalization outcomes. Study limitations require validation of all the findings in independent studies.
Introduction. To analyze the efficacy and safety of treatment tactics for term patients diagnosed with TTN in an ICU without venous access and parenteral nutrition.Materials and methods. The study gives a retrospective analysis of the medical records of 241 ICU patients from January 2020 to March 2021. 83 children meet general criteria for inclusion in the study.Results and Discussion. While comparing the study group and the control group, no significant difference was detected in the incidence of risk factors during pregnancy and childbirth, such as gestational diabetes, ARVI during pregnancy, chorioamnionitis, preeclampsia, and the frequency of a prolonged anhydrous period, the frequency of induced labor, delivery by caesarean section, fetal distress and the use of vacuum extraction. Despite the same initial level of severity of respiratory disorders, when the child was admitted to the ICU, the duration of CPAP therapy was significantly higher in the control group: 7.5 (5.5-12) versus 5 (4-6) hours p = 5×10-5. The average length of hospital stay in the ICU and the total length of hospital stay was significantly higher in the control group (p = 4×10-11 and p = 0.006, respectively), as well as the need for treatment in the Neonatal Pathology unit conditions (p = 0.001).Conclusion. Analyzing the tactics of treating term patients diagnosed with TTN, the study proved that children without venous access require less time for respiratory therapy with CPAP in the NICU, the total duration of hospitalization in the NICU is significantly lower, as well as the need for additional treatment in the Neonatal Pathology unit. The study revealed that the early onset of enteral nutrition and the rapid expansion of the feeding portion, provided with child’s stable health condition, enable to avoid the installation of venous access and the prescription of parenteral nutrition at the ICU stage.
