Outcomes of newborns with tracheostomy: single center experience.

BACKGROUND: Babies with severe bronchopulmonary dysplasia (BPD) are discharged with the support of a home-type mechanical ventilator, after opening a tracheostomy. In addition, although rare, tracheostomy is required in the neonatal period in congenital airway malformations. Early tracheostomy is appropriate to prevent complications due to prolonged intubation. We aimed to find the appropriate time for tracheostomy by examining the tracheostomy opening and closing times, complications and demographic characteristics of the patients, who were hospitalized and underwent tracheostomy in our neonatal intensive care unit. METHODS: This retrospective study involved infants admitted to the neonatal intensive care unit between January 2014 and 2019 and discharged following tracheostomy. Information acquired from hospital data was enrolled. The protocol was registered with ClinicalTrials.gov identifier NCT04497740. RESULTS: Twenty-six neonates with median 27.5 weeks gestational age and birth weight 885 gr were enrolled in the study. The mean opening time for tracheostomy was 54 ± 24 days, and the postmenstrual age (PMA) was 36 ± 3 weeks. The mean time to closure of tracheostomy in newborns with a tracheostomy was 387 ± 164 days. The duration of accidental decannulation developed as an early complication in 8 patients was mean 11 ± 8 days. Aspiration pneumonia in 2, subglottic stenosis in 5, accidental decannulation in 2, suprastomal collapse in 7, tracheocutaneous fistula in 8 and granulation tissue in 2 patients were found to be late complications, which occurred within median 90 days. CONCLUSIONS: If there is no evidence that breathing has improved and the patient is still using a mechanical ventilator at high pressures and high oxygen concentration, a tracheostomy placement should be considered within two months.

Prospective Evaluation of the Correlation of Lung Ultrasonography Score and Blood Gas Parameters in Neonates With Respiratory Distress.

Introduction Lung ultrasonography (LUS) has become frequently used in neonatal intensive care units (NICU) because it is diagnostic, useful, harmless, radiation-free, and practical for bedside use due to its portability. Objective This study aimed to evaluate the association between lung ultrasound (LUS) scores and diagnoses of neonates hospitalized for respiratory distress and determine the value of the combined use of laboratory and imaging methods in patient evaluation by looking at the correlation between blood gas parameters and LUS score. Materials and methods Between March and July 2022, a total of 55 patients who were born term or premature and admitted due to respiratory distress in the NICU of Malatya Training and Research Hospital were included in the study. In this observational, prospective study, demographic information such as birth weights, gestational weeks, mode of delivery, Apgar scores, blood gas sample results, LUS results and scores, ventilation types, and discharge time were recorded during hospitalization in our unit. According to the newborns' clinical, laboratory, and radiologic evaluations, the diagnoses of respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), or congenital pneumonia were made, and the relationship between the diagnoses and LUS scores was evaluated. The pH value and PCO2 value in the venous blood gas obtained on the day of LUS were recorded. Correlation analysis was performed between the LUS score and pH value, LUS score and PCO2 value. Results Twenty-seven newborns were diagnosed with TTN, 18 with RDS, and 10 with congenital pneumonia. There was a statistical difference between LUS scores and diagnoses (p<0.001). According to Spearman correlation analysis, a significant negative moderate correlation was found between LUS scores and venous blood gas pH value (p<0.001, r:-0.49). There was also a significant positive low, moderate correlation with venous blood gas PCO2 value (p<0.001, r:0.36). Conclusion This study demonstrates that LUS scoring has a role in determining the severity of disease and making diagnoses in patients hospitalized for respiratory distress. When LUS is widely used, it will be informative about the severity and prognosis of the disease, together with laboratory evaluation.

Effect of prostaglandin-E1 treatment on pyloric wall thickness in newborns with ductal-dependent critical congenital heart diseases.

BACKGROUND: Prostaglandin E1 (PGE1) is used in the medical treatment of ductal-dependent critical congenital heart disease (CCHD) in neonates. Apnea/bradycardia, hypotension, hypokalemia, and fever are the most important side effects of PGE1. Moreover, gastric outlet obstruction has been reported in a few case reports. A prospective study was conducted to investigate the effect of PGE1 treatment on pyloric wall thickness in newborns with congenital heart diseases. METHODS: A total of 22 newborns with ductal-dependent CCHD having PGE1 infusion longer than a week were included in this study. Ultrasonographic measurements were performed before and one week after the PGE1 infusion to evaluate the pyloric thickness and length. The protocol was registered with ClinicalTrials.govidentifier NCT04496050. RESULTS: A total of 22 neonates with mean gestational age 38 ± 1.8 weeks and birth weight 3105 ± 611 gr were enrolled in the study. The median time of the second ultrasound was seven days. The median cumulative dose of PGE1 given during this period was 108 mcg/kg/min. There was a statistically significant increase in post-treatment pyloric thickness and length compared to pre-treatment measurements (p < 0.001, p < 0.001). None of the patients with increased thickness and pyloric muscle length presented any symptoms. CONCLUSION: PGE1 treatment significantly increased the pyloric thickness and length after at least one-week treatment. PGE1 with its action mechanism is likely to cause gastric outlet obstruction, although not exactly pyloric stenosis on the condition used for a long time.

Lung ultrasonography decreases radiation exposure in newborns with respiratory distress: a retrospective cohort study.

Chest X-ray (CXR) is commonly used as a first-line imaging method to determine the cause of respiratory distress in NICUs. The aim of the study was to retrospectively assess the decrease in the number of CXRs performed due to the use of lung ultrasonography on the first day of life for newborns with respiratory distress. Infants who were admitted to the NICU on the first day of life due to respiratory distress were enrolled in this study (ClinicalTrials.gov identifier NCT04722016) and divided into two groups: the study group (n = 104) included patients born between January 2019 and June 2020, and the historical control group (n = 73) included patients born between June 2017 and December 2018. As a first-line technique for lung imaging, only CXR had been used in the historical control group, whereas ultrasound had been preferred in the study group. The radiation dose to the newborns and the number of CXRs performed in the first day of life were compared between the two groups. Significant reductions in the number of CXRs performed and radiation exposure were observed in the study group. The radiation dose decreased from 5.54 to 4.47 µGy per baby when LUS was routinely used. The proportion of patients who underwent CXR decreased from 100 to 71.2%.Conclusion: We observed that using lung ultrasonography as a first-line evaluation method in neonates with respiratory distress decreased both the number of CXRs performed and radiation exposure. What is Known: • Chest X-ray is commonly used as a first line imaging method to diagnose the reason of respiratory distress in NICUs. • Lung ultrasound is a new diagnostic tool for lung imaging. What is New: • With the use of lung ultrasonography, radiation exposure of both newborns and healthcare workers can be reduced. • This retrospective study revealed that most of the babies with respiratory distress were treated without CXR.
