BackgroundAlthough several different types of natural surfactants are available, including Alveofact, Curosurf, and Survanta, the preferred type and the magnitude of their effects are unknown.ObjectivesThis study was designed to compare the effects of these three surfactants on the gas exchange and clinical outcomes of neonates with respiratory distress syndrome (RDS).MethodsThis triple-blind randomized clinical trial studied all preterm neonates ≤ 37 weeks with RDS who were admitted to the neonatal intensive care unit (NICU) of Taleghani hospital (Tabriz, Iran) between 2012 and 2013. The patients were divided into three groups, each of which received one of these surfactants. The incidences of ventilator dependency, patent ductus arteriosus (PDA), broncho-pulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH), hospital-stay length, and continuous positive airway pressure (CPAP) failure, as well as blood gas levels, were recorded as endpoint measurements and compared.ResultsIn total, 165 neonates of gestational age ≤ 37 weeks with RDS were examined. Neonates were allocated to three different groups randomly, including a Survanta group (n = 49), a Curosurf group (n = 62), and an Alveofact group (n = 54). The mean gestational age of the neonates was 31.6 ± 3.7 weeks, and their mean weight was 1,840 ± 790 grams. The male/female ratio was 2:1 (67% male, 33% female); 104 (63%) neonates were ≤ 32 weeks gestational age, and 61 (37%) were >32 weeks. There were no significant differences for gender or demographic characteristics among the neonates in relation to the type of applied surfactant. According to the clinical parameters (BPD, IVH, ROP, hospital-stay length, and mechanical ventilation requirement), no significant differences were observed between the groups before and after surfactant administration, but the differences between the Survanta and Alveofact groups for the incidence rates of pneumothorax (P = 0.03) and pulmonary hemorrhage (P = 0.03) were statistically significant.ConclusionsNo significant differences were observed in most of the clinical variables between the three types of natural surfactant, but in neonates ≤ 32 weeks, the incidence of pneumothorax was significantly higher in the Alveofact group; in neonates > 32 weeks, the incidences of PDA, mean hospital-stay length, and mean mechanical ventilation time were also significantly higher in the same group. It thus appears that Curosurf and Survanta replacement therapies among premature neonates with RDS perform better than Alveofact replacement therapy.

Background:Tracheal intubation is extremely distressing, painful, and may influence heart rate and blood pressure. Sedatives, analgesics, and muscle relaxants are not commonly used for intubation in neonates.Objectives:This study aimed to evaluate the effects of lidocaine spray as a non-intravenous drug before neonatal intubation on blood pressure, heart rate, oxygen saturation and time of intubation.Patients and Methods:In a randomized, controlled study each neonate was randomly assigned to one of the two study groups by staffs who were not involved in the infant's care. The allocation concealment was kept in an opaque sealed envelope, and the investigators, the patient care team, and the assessors were blinded to the treatment allocation. The selected setting was NICU unit of a teaching hospital in Ilam city, Iran and participants were 60 neonates with indication of tracheal intubation with gestational age > 30 weeks. Patients in the treatment group received lidocaine spray and the placebo group received spray of normal saline prior to intubation. Main outcome measurements were the mean rates of blood pressure, heart rate, oxygen saturation, intubation time and lidocaine side effects were measured before and after intubation.Results:Totally 60 newborns including 31 boys and 29 girls were entered into the study (drug group n = 30; placebo group n = 30). Boy/girl ratio in treatment and placebo groups were 1.3 and 0.88, respectively. Mean age ± SD of participants was 34.1 ± 24.8 hours (treatment: 35.3 ± 25.7; placebo: 32.9 ± 24.3; P < 0.0001). Mean weight ± SD of neonates was 2012.5 ± 969 g. Application of lidocaine spray caused a significant reduction of mean intubation time among treatment group compared with placebo group (treatment: 15.03 ± 2.2 seconds; placebo: 18.3 ± 2.3 seconds; P < 0.0001). Mean blood pressure, heart rate and oxygen saturation rate, among neonates in treatment group was reduced after intubation compared with their relevant figures before intubation; however, their differences were not statistically significant except for mean oxygen saturation rate that was reduced significantly in placebo group. No side effects were observed during study.Conclusions:Though the current study revealed some promising results in the application of lidocaine spray during neonatal intubation without any considerable side effects; however, the current investigation could only be considered as a pilot study for further attempts in different locations with higher sample sizes and in different situations.

Background: To date there is no effective drug treatment for transient tachypnea of the newborn (TTN) and respiratory support is the only means to handle this disease. This study was performed to evaluate the effect of albuterol (Salbutamol) in improvement of respiratory distress in involved neonates.

Background. Children's meningitis is associated with many complications and deaths. Therefore, it is critical to develop reliable and available methods to predict these complications, diagnose them in a timely manner, and prevent the progression of complications. This study aimed to investigate the findings of computed tomography (CT) scan in patients with meningitis and evaluate its association with prognosis. Methods. In this cross-sectional analytical study, we investigated the clinical files of 100 patients with meningitis (preferably bacterial meningitis) in Tabriz Children's Hospital, Iran between 2013-2017. The results of CT scan and disease complications were recorded and analyzed by statistical software. Results. Common symptoms identified in the patients included fever (88%), nausea and vomiting (36%), headache (27%), and convulsions (25%). Also, the results of CT scan included cerebral effusion (16%), hydrocephalus (7%), diffuse cerebral edema (7%), and cerebral atrophy (4%). Statistical analysis indicated a statistically significant association between the complications of meningitis (learning disorder, epilepsy, and hearing disorder) and the results of CT scan (cerebral effusion, diffuse cerebral edema, and hydrocephalus). Conclusion. CT scan can be used as an early diagnostic and prognostic method in children with meningitis. Practical Implications. Meningitis is associated with many complications and deaths, and the lack of diagnostic methods and accurate prognosis is one of the important challenges in this field. Therefore, identifying and introducing accurate and cheap methods for predicting these complications and taking early measures to prevent the development of complications and treatment can be beneficial. The results of the present study showed that CT scan can be used as an early diagnostic and prognostic method in children with meningitis.
