    (2014) Yapakci, Ece; Ecevit, Ayse; Torer, Birgin; Ince, Deniz Anuk; Gokdemir, Mahmut; Gulcan, Hande; Tarcan, Aylin; https://orcid.org/0000-0002-2232-8117; https://orcid.org/0000-0002-4369-2110; https://orcid.org/0000-0002-5676-2747; 23816200; AIC-4823-2022; AAJ-4616-2021; I-6746-2016; N-4174-2014
    Background: This study aimed to examine the differences between arterial and inferior caval vein oxygen saturation, fractional oxygen extraction, and the shunt index, which were calculated in the diagnosis of patent ductus arteriosus. Methods: Twenty-seven preterm infants were included in this study and were divided into two groups according to patent ductus arteriosus. Among them, 11 (41%) infants had haemodynamically significant patent ductus arteriosus and 16 (59%) did not have significant patent ductus arteriosus. Synchronous arterial and venous blood gases were measured during the first post-natal hours after the insertion of umbilical catheters. The differences between arterial and inferior caval vein oxygen saturation, inferior body fractional oxygen extraction, and the shunt index were calculated. Echocardiography was performed before the 72nd hour of life in a selected group of patients who had haemodynamically significant patent ductus arteriosus. Ibuprofen treatment was administered to patients with patent ductus arteriosus. Echocardiography was performed on the 72nd hour of life in preterm infants without any clinical suspicion of patent ductus arteriosus. Results: The early measured differences between arterial and inferior caval vein oxygen saturation and inferior body fractional oxygen extraction were found to be lower and the shunt index was found to be higher in the haemodynamically significant patent ductus arteriosus group than in the group without haemodynamically significant patent ductus arteriosus. Conclusion: We found that the shunt index, calculated in the first hours of life as >= 63%, predicted haemodynamically significant patent ductus arteriosus with a sensitivity of 78% and specificity of 82% in preterm newborns.

    Severe Hypernatremia Associated Catheter Malposition in An Intensive Care Patient
    (2016) Silahli, Musa; Gokdemir, Mahmut; Duman, Enes; Gokmen, Zeynel; 0000-0003-0944-7178; 0000-0002-2746-0547; 0000-0002-5676-2747; 27555161; AAB-5059-2022; AAX-9343-2021; AAJ-8069-2021; N-4174-2014
    We present a catheter related severe hypernatremia in a 2-month-old baby who was admitted to the pediatric intensive care. Imbalance of plasma sodium is commonly seen in pediatric intensive care patients. The water and sodium balance is a complex process. Especially, brain and kidneys are the most important organs that affect the water and sodium balance. Other mechanisms of the cellular structure include osmoreceptors, Na-K ATPase systems, and vasopressin. Hypernatremia is usually an iatrogenic condition in hospitalized patients due to mismanagement of water electrolyte imbalance. Central venous catheterization is frequently used in pediatric intensive care patients. Complications of central venous catheter placement still continue despite the usage of ultrasound guidance. Malposition of central venous catheter in the brain veins should be kept in mind as a rare cause of iatrogenic hypernatremia. (C) 2016 Elsevier Inc. All rights reserved.

    The Relationship Between Placental Transfusion, and Thymic Size and Neonatal Morbidities in Premature Infants - A Randomized Control Tiral
    (2018) Silahli, Musa; Duman, Enes; Gokmen, Zeynel; Toprak, Erzat; Gokdemir, Mahmut; Ecevit, Ayse; 0000-0002-2746-0547; 0000-0002-2877-1232; 0000-0002-5676-2747; 0000-0002-2232-8117; 30410129; AAX-9343-2021; AAJ-8069-2021; ABI-5902-2020; N-4174-2014; AAJ-4616-2021
    Objectives: To compare the effect of umbilical cord milking and early cord clamping on thymic size, and neonatal mortality and morbidity in preterm infants. Methods: This single-center, prospective, double-blind, randomised controlled study was conducted at Baskent University, Konya Education and Research Centre, Konya, Turkey, between October 2015 and April 2016. Pregnant women who delivered before 32 weeks of gestation were randomised to receive umbilical cord milking (group 1) or early cord clamping (group 2). Ultrasonographic evaluation was performed in each newborn by an experienced radiologist within the first 24 hours of life. Thymic size was estimated in line with literature. SPSS 15 was used for all data analyses. Results: There were 38 subjects in group 1 and 37 in group 2. There were as many infants in the two groups (p>0.05) The haemoglobin levels was higher in group 1, but not significantly (p=0.213). The absolute neutrophil count in group 1 was significantly lower (p=0.017) than group 2. In terms of neonatal mortaility and morbidity, there were no significant differences between the groups (p>0.05). Conclusion: Umbilical cord milking was not associated with thymic size during the the first 24h of life.

    New Approach in Stage 1 Surgery for Hypoplastic Left Heart Syndrome: Preliminary Outcomes
    (2023) Celik, Mehmet; Gokdemir, Mahmut; Cindik, Nimet; Gunaydin, Asim C.; Aygun, Fatih; Ozkan, Murat; 0000-0002-5018-0068; 0000-0002-5676-2747; 36004405; AAT-2031-2021; N-4174-2014
    Objectives: We present the short-term results of an alternative method in stage 1 surgery for hypoplastic left heart syndrome. Methods: Data of 16 consecutive patients who were treated with the novel method in our clinic between February 2019 and March 2021 were analysed retrospectively. Preoperative data and postoperative follow-up were recorded. Results: Of the 16 operated patients, 12 were diagnosed with hypoplastic left heart syndrome, while four were diagnosed with hypoplastic left heart syndrome variants. Seven patients died during early postoperative period. One patient died at home waiting stage 2 surgery. Three patient underwent stage 2 surgery. Pulmonary artery reconstruction was performed in one patient due to left pulmonary artery distortion. Conclusions: We believe that our method can be an effective alternative in the surgery of hypoplastic left heart syndrome and its variants. It is hoped that with increasing number of studies and more experience better outcome will be achieved.
