Objective: The aim of our study was to determine whether lipid solutions delivered separately or in mixture with total parenteral nutrition (TPN) solutions effect the balance between oxidant and antioxidant levels in premature infants., Methods: A total of 60 preterm newborns who were delivered at their 30-34 gestational weeks and received TPN were included in the study. Premature newborns were randomized into two groups based on the delivery method of the lipid solution, separately (Group 1) or in mixture with TPN solutions (Group 2). Total antioxidant status (TAS), total oxidant status (TOS) and paraoxonase (PON-1) levels were analyzed in both blood samples, and oxidative stress index (OSI) was also calculated., Results: Thirty cases from both groups were included in the study. Statistically significant decrease in the level of TAS and increase in the level of PON-1 were detected at 72 h of TPN therapy in both groups (p < 0.05). Statistically significant decrease in both TOS and OSI levels were observed in Group 2 (p < 0.05). In association with these findings, any statistically significant intergroup difference was not detected in both parameters regarding oxidant balance (p > 0.05)., Conclusion: Our study showed that according to lipid administration method any difference for oxidant-antioxidant balance was not detected.

Objectives: The purpose of this study was to compare the efficacy and safety of two different catheterization techniques of exchange transfusion (ET) used in the therapy of newborn jaundice: fully automated two-way ET technique and the classical one-way ET., Patients and Methods: The study included babies at gestational age of >34 weeks. In total, 107 ETs were performed on 86 babies. Totally, the umbilical vein (UV) group included 54 babies having undergone 69 ETs and the UV/UA group included 32 babies having undergone 38 ETs., Results: The declines in bilirubin levels right after ET (p = 0.018) and 8 h after ET (p = 0.014) were higher in the fully automated UV/UA technique than in the classical UV technique. Furthermore, the duration of intensive phototherapy following ET was shorter in the UV/UA method than in the UV method (p = 0.003). There was no difference between the two methods in terms of ET-associated complications (p = 0.927)., Conclusions: In neonatal hyperbilirubinemia, ET with fully automated UV/UA technique is more efficient than the classical ET technique, causing no additional side-effects. It is also more physiological than the classical technique, since it minimizes the fluctuations in the blood volume and intravascular pressure during ET.
