Comparison of two different Nasal Interfaces used in Non-Invasive Respiratory support in terms of Neonate comfort.

Background: Non-Invasive Ventilation (NIV) is the first choice approach in neonates with sufficient respiratory effort that require respiratory support. The type of nasal interface used in NIV affects both efficacy and patient comfort. The aim of this study is to investigate the effects of different nasal interfaces used in NIV support on neonatal patient comfort. Methods: Our study evaluated patients who received NIV support for 24 hours. The patients were randomly divided into two groups according to the type of nasal interface used, which were RAM cannula and short binasal prong (SBP). The patients' demographic and clinical data were noted. Their sleep was monitored for 24 hours with an actigraphy device. Results: A total of 82 patients were evaluated. The sleep efficiency in the RAM cannula group was significantly higher (respectively, 65.7% [10.22-95.25] vs. 57.81% [2.49-77], p=0.004). Although not statistically significant, the neonates in the RAM cannula group exhibited longer total sleep time (respectively, 10.4 ± 4.28 hours vs. 9.02 ± 3.73 hours, p=0.161). Comparison of heart rates and respiratory rates indicate that the patients in the RAM cannula group were more comfortable. Conclusions: Our study found that infants who received NIV support through a RAM cannula experienced more efficient sleep. Holistic approaches in neonatal intensive care units are vital for better neurodevelopmental outcomes in newborns. Although non-invasive, the interface used in NIV should also be a part of this holistic approach.

Combined (dual) drug therapy for the treatment of patent ductus arteriosus: last approach prior to ligation.

OBJECTIVE: We aimed to evaluate the efficacy of combined (ibuprofen+paracetamol) medical therapy in cases of persistent haemodynamically significant patent ductus arteriosus that are resistant to standard medical monotherapy (ibuprofen and/or paracetamol) in this retrospective multi-centre study. METHODS: The combined therapy included the administration of 15mg/kg/dose of paracetamol every 6 h for 3 days and ibuprofen at an initial dose of 10mg/kg/dose followed by 5 mg/kg/dose every 24 h. After 2 days following the administration of the last dose, the researchers evaluated the efficacy of combined treatment by conducting an echocardiographic examination. RESULTS: Of all 42 patients who received combined therapy, 37 (88.1%) patients exhibited closure of the haemodynamically significant patent ductus arteriosus without requiring surgical ligation. Patients who did not respond to combined therapy had a higher mean birth weight and gestational age compared to those who responded (p < 0.05). CONCLUSION: The researchers believe the success of ibuprofen and paracetamol in haemodynamically significant patent ductus arteriosus treatment may be due to their synergistic efficacy and inhibition of the prostaglandin synthesis pathway through different enzymes. The results of our retrospective trial suggest that combination therapy with paracetamol and ibuprofen can be attempted when monotherapy is unsuccessful in treating haemodynamically significant patent ductus arteriosus, especially in centres without a surgical department.

Neurodevelopmental evaluation of newborns who underwent hypothermia with a diagnosis of hypoxic ischemic encephalopathy based on the Bayley-III scale.

Background/aim: Hypoxic ischemic encephalopathy (HIE) is one of the common causes of mortality and morbidity in newborns. Despite therapeutic hypothermia, an important treatment with proven efficacy, the morbidity and mortality rates remain high. The aim of this study was to neurodevelopmentally evaluate patients who underwent therapeutic hypothermia. Material and method: Included herein were patients who underwent hypothermia between 2018 and 2020. Their medical files were reviewed retrospectively, and their demographic and clinical information was recorded. Patients whose contact information was available were called to the developmental pediatrics outpatient clinic for a neurodevelopmental evaluation. The Bayley Scales of Infant and Toddler Development 3rd Edition (Bayley-III) was used as the evaluation tool. Laboratory values and clinical parameters of the patients were further analyzed. Results: It was found that 42 patients underwent hypothermia in 3 years, of whom 14 (33.3%) had died. Of the 28 patients who were discharged, 20 children could be reached, and a neurodevelopmental evaluation was performed. Developmental delay in the cognitive area was detected in 11 (55%) patients, delay in the language area was found in 9 (45%) patients, and delay in the motor area was found in 11 (55%) patients. The correlation and regression analysis results determined that the time to start cooling was the most effective common factor in all 3 fields of scoring. Conclusion: The time to start cooling is related to the neurodevelopmental outcomes of patients with HIE. The earlier cooling is started, the better the neurodevelopmental results. Despite therapeutic hypothermia, the neurodevelopmental development of infants may be adversely affected. These patients should be followed-up neurodevelopmentally for a long time.

Mortality related factors on hypoxic ischemic encephalopathic patients treated with therapeutic hypothermia: an 11-year single-center experience.

BACKGROUND: Hypoxic-ischemic encephalopathy (HIE) is a condition that may cause multiple organ dysfunction and has a high rate of mortality and morbidity. Therapeutic hypothermia is the only proven treatment that decreases the sequel and mortality rate of neonates that are born after 36 weeks of pregnancy and have moderate-severe HIE. METHODS: Our study was a single-center, retrospective study that includes newborns (gestational age ≥ 36 weeks) who underwent therapeutic hypothermia due to hypoxic-ischemic encephalopathy between 2010 and 2020. We evaluated 125 patients who were diagnosed with moderate to severe HIE and received therapeutic hypothermia. Demographic and clinical data were obtained from electronic medical records and patient files. The patients were separated into two groups as exitus group (n = 39) and discharged group (n = 86). We aimed to evaluate factors affecting mortality. RESULTS: We determined that the median resuscitation times were longer in the delivery room [retrospectively, 10th minutes (0-30) vs. 1 min (0-20), p < 0.05], the tenth min APGAR scores were lower [respectively, 4 (0-7) vs. 6 (3-10), p < 0.05], and the median pH value in the first blood gas taken was lower [respectively, 6.87 (6.4-7.14) vs. 6.90 (6.58-7.12), p < 0.05] in the exitus group. We also determined that multiple organ dysfunction is seen more often in the exitus group. DISCUSSION: This study demonstrated that the depth of acidosis in the blood gas, multiple organ dysfunction, and the existence of early-onset seizures are the signs of poor prognosis. Therefore, physicians need to be aware of such prognostic factors to follow these patients more closely in terms of possible complications and to inform their parents.

Gyrate atrophy of the choroid and retina with hyperornithinemia, cystinuria and lysinuria responsive to vitamin B6.

In this report, an 8-year-old girl is presented with the complaint of progressive night blindness. The authors have performed eye funduscopy, which showed chorioretinal atrophy in gyrate shape. A high level of plasma ornithine was determined. Urinary excretion of ornithine as well as lysine and cystine were increased. Patient was treated with high dose pyridoxine supplement (500 mg/dl). The night blindness condition of the patient improved. After 1 month of pyridoxine therapy ornithine level of her plasma was successfully reduced and blindness improved.
