Aim: Early hemodynamic assessment of global parameters in critically ill newborns fails and requires mostly invasive measurements in neonatal intensive care unit. Clinical signs are frequently used for assessment of peripheral perfusion. Perfusion index (PI) is a new noninvasive numerical value of peripheral perfusion. Serum lactate levels and PI are the indicators that are important in determining prognosis of preterm infants. In this study, we aimed to investigate the relationship of serum lactate levels and PI with mortality and morbidity in very low-birth weight infants (VLBW). Study design: This study was conducted between July 2014 and July 2015 in a Level III NICU. The study enrolled preterm infants with a gestational age ≤ 32 weeks, birth weight ≤ 1500 g. Serum lactate levels from blood gases and PI, SpO2 measurements were recorded at 1st, 12th and 24th hours by using a new generation pulse-oximeter. Morbidities and mortalities were documented. Results: A total of 60 VLBW infants were enrolled the study. Mean birth weight and gestational age were 991 ± 288 g and 27.5 ± 2.5 w, respectively. Retinopathy of prematurity (ROP) was significantly higher in the patients with high lactate levels (>4 mg/dl) at 1st hour and low-PI levels (<0.5) at 12th hour of life (p = 0.042, p = 0.015), respectively. Bronchopulmonary displasia (BPD) was significantly higher in the patients with low PI (< 0.5) at 1st hour. Lactate and PI values were not significantly correlated with necrotizing enterocolitis, intraventricular hemorrhage, patent ductus arteriosus, sepsis and mortality. Conclusion: High lactate levels (> 4 mg/dl) and low PI (< 0.5) could be used as early parameters for prediction of ROP and BPD. This data suggests that in VLBW infants lactate levels and PI parameters during the first 24 h will be effective in determining the prognosis of the disease. We believe that larger, randomized controlled clinical trials are likely to establish the true benefit.

Studies in infants with hypoxic-ischemic encephalopathy (HIE) due to perinatal asphyxia have generally focused on neurological outcomes. Although acute kidney injury (AKI) rate decreased in advent of therapeutic hypothermia (TH), it is still a common and important entity. In this retrospective study, we aimed to investigate the risk factors for AKI in HIE patients treated with hypothermia. Infants treated with TH due to HIE were reviewed retrospectively and infants who developed AKI and not were compared. Ninety-six patients were enrolled in the study. AKI developed in 27 (28%) patients and 4 (14.8%) of them were stage III AKI. In the AKI group, gestational age of the patients was significantly higher ( p = 0.035), the 1st minute Apgar score was significantly lower ( p = 0.042), and convulsions (p = 0.002), amplitude-integrated electroencephalography disorders ( p = 0.025), sepsis ( p = 0.017), need for inotropic therapy ( p = 0.001), need of invasive mechanical ventilation ( p = 0.03), and systolic dysfunction in echocardiography ( p = 0.022) were significantly higher. In logistic regression tests, Apgar score at the 1st minute was found to be independent risk factor for developing AKI. AKI has the potential to worsen the neurological damage and correlates with morbidities of perinatal asphyxia. It is important to determine the incidence and risk factors for developing AKI in this delicate group of patients to prevent further renal damage.

Objectives and Aim: The primary aim of this study was to conduct a comparative analysis of the safety and efficacy of levetiracetam (LEV) and phenobarbital (PB) as first-line treatments for neonatal seizure management. This study was designed to measure and compare the incidence of adverse effects and to determine the discharge and mortality rates associated with the use of these antiseizure medications (ASMs). Through this comparison, this research sought to provide insights to optimise care for neonates experiencing seizures. Materials and Methods: This retrospective cohort study evaluated 104 neonates treated for seizures at Zeynep Kamil Hospital from 2015 to 2020 after excluding those on non-PB/LEV antiseizure medications. Seizures were characterised using electroencephalogram (EEG) and categorised according to aetiology and frequency. Treatment efficacy was gauged by seizure cessation, as confirmed using EEG. Adverse effects and demographic data were recorded. Statistical analyses were conducted using SPSS, employing the Shapiro–Wilk, independent t-test, Mann–Whitney U test, and chi-square test, with a significance threshold of p < 0.05. Results: Overall, 104 neonates treated with first-line ASM were evaluated for efficacy; PB was administered in 68.26% of the cases, while LEV was utilised in 31.74%. The total complete response rate was 40.38%, with no significant difference between the PB and LEV groups (p = 0.309). The incidence rate ratios (IRRs) demonstrated that seizure frequency profoundly influenced treatment effectiveness, with IRRs of 2.09 for rare seizures, 3.25 for frequent seizures, and 4.01 for status epilepticus, indicating a higher treatment response rate with increasing seizure frequency. For second-line treatment, among a subset of 62 patients, PB had a slight, non-significant advantage over LEV, with an odds ratio of 1.09, suggesting a marginally better response to LEV. Adverse events were significantly more frequent in the PB group, affecting 19 of 67 neonates (28.36%), compared to only 2 of 71 neonates (2.82%) in the LEV group (p < 0.001). No significant difference was observed in the discharge rates between the two groups (PB, 67.61%; LEV, 75.76%; p = 0.674). Interestingly, the mortality rate was significantly higher in the LEV group (45.45%) than that in the PB group (22.54%; p = 0.045). Conclusion: This study underscores LEV’s superior safety profile over PB in neonatal seizure management, evidenced by a significantly lower rate of adverse events. PB seems to be more effective in the second-line treatment of neonatal seizures. Despite the lack of significant differences in the discharge rates, the higher mortality rate associated with LEV warrants further investigation. These findings advocate the cautious selection of antiepileptic drugs in neonatal care, with a preference for LEV based on its safety profile.

Background: Ultrasonography is widely used in neonatological practice and studies investigating the hemodynamic effects of various treatment protocols or clinical situations. On the other hand, pain causes changes in the cardiovascular system; so, in the case of ultrasonography leading to pain in neonates, it may cause hemodynamic alterations. In this prospective study, we evaluate whether ultrasonographic application causes pain and changes in the hemodynamic system. Methods: Newborns undergoing ultrasonographic examination were enrolled in the study. Vital signs, cerebral and mesenteric tissue oxygenation (StO₂) levels, and middle cerebral artery (MCA) Doppler measurements were recorded, and NPASS scores were calculated before and after ultrasonography. Results: We enrolled 39 patients in the study. After ultrasonography, Neonatal Pain, Agitation, and Sedation Scale (NPASS) scores were significantly higher (p < 0.01), and all vital signs (heart rate, respiratory rate, SpO₂, diastolic and systolic blood pressure; p = 0.03; p < 0.01, p < 0.01, p < 0.01, p = 0.02, p = 0.03, respectively) were altered. Cerebral (p = 0.008) and mesenteric (p = 0.039) StO₂ levels were significantly lower in the whole study group, MCA end-diastolic velocity decreased (p = 0.02), and the resistive index (p = 0.03) increased in patients whose NPASS score was >7 after ultrasonography. Conclusions: This study is the first to show that ultrasonography may cause pain in newborn patients, and alters vital signs and hemodynamic parameters. Therefore, precautions should be taken to protect newborn babies from pain during ultrasound applications, as they are already exposed to many noxious stimuli. Furthermore, pain scores should be considered in studies using ultrasonography and evaluating hemodynamic parameters to increase the reliability of the studies.
