Objective: We aimed to examine the demographic characteristics, etiology and postoperative mortality rates of neonates operated on in our hospital. Methods: The records of neonates who were operated in our tertiary care level university hospital between 2013 and 2019 were reviewed retrospectively. Patients with a diagnosis requiring surgical procedure, age (days), gender, anatomical region where the surgical procedure was performed, length of hospital stay, and mortality rates were investigated. Results: 329 neonates were included in the study of which 213 (64.75%) were male and 116 (35.25%) were female. Gastrointestinal system surgery was performed in 214 patients (65.04%), respiratory system surgery in 95 (28.87%) patients and urogenital system surgery in 17 (5.16%) patients. The mortality rate of 156 patients that were followed up in our neonatal unit in the postoperative period was 16.6%. The mortality rate of female babies (21.3%) was higher than that of male babies (13%). Considering the mortality rates of the patients according to the surgical areas, the highest mortality rate was found in respiratory system surgery (38.46%) which was trailed by gastrointestinal system surgery (12.28%) and urogenital system surgery (7.69%), respectively. Conclusions: Despite advances in neonatal care and surgical techniques, immaturity and congenital anomalies still have an important place among the most common causes of death in infants. In particular, the detection of organ dysfunctions due to congenital anomalies which are considered among the preventable causes of death in infants, efforts to correct them will be beneficial to a certain extent in reducing the mortality rates of neonates.

Objectives: In this study, we aimed to investigate the effects of spinal anesthesia on the QT interval in patients with term and post-term pregnancy that were scheduled for elective cesarean section.Materials and methods: Forty pregnant women scheduled for elective cesarean section under spinal anesthesia were assigned into two groups: Post-term group (Group P) (n = 20) and Term group (Group T) (n = 20). After entering the operation room, standard monitoring [electrocardiography (ECG), noninvasive blood pressure, heart rate, respiratory rate, and peripheral oxygen saturation] was performed. The patient was placed in the sitting position and spinal anesthesia was performed with a median approach at the L3-L4a level using a 25G Quincke-type spinal needle. After cerebrospinal fluid was viewed, 12.5 mg (2.5 mL) hyperbaric bupivacaine was administered intrathecally over 1 min. Other ECG records were made at min 1 (T1), 5 (T2), and 10 (T3) after the induction of spinal anesthesia and after skin closure (T4). QT and QT dispersion were measured from ECG. Heart rate-corrected QT (QTc) and QT dispersion (QTcd) values were calculated using the Bazett formula.Results: Demographic characteristics of the patients were similar in both groups. Postoperative QTc, QTd, and QTcd values were significantly increased in Group P compared to those in Group T (p < .05).Conclusion: Spinal anesthesia led to increased postoperative QTc, QTd, and QTcd values in the patients with a gestational age of ≥42 weeks who underwent cesarean section. Accordingly, it is advisable to perform postoperative strict cardiac monitoring particularly in post-term pregnant women undergoing spinal anesthesia. [ABSTRACT FROM AUTHOR]

A letter to the editor is presented which discusses the treatment of hypermagnesemia and its link to acute respiratory and renal failure.

Background: The preference for peripheral nerve block methods is increasing with every passing day. Our aim in this study is to evaluate tissue oxygenation using a near-infrared spectroscopy (NIRS), as a non-invasive device that detects tissue oxygen saturation (St02), in patients subjected to infraclavicular blockage at different angles., Method: Included in the study were 34 patients aged between 18 and 65 in the ASA I-II group who were scheduled to undergo hand, forearm or arm surgery. An infraclavicular block was applied with the shoulder abducted at 0°, 45° and 90° under USG guidance while the elbow was in extension. The St02 values of the patients were measured with NIRS in both arms every five minutes., Results: A p value of <0.05 was considered statistically significant. Tissue oxygenation in the arm subjected to blockade increased significantly over time (p<0.001), while tissue oxygenation in the untreated arm did not change over time. The duration of the sensory blockade differed significantly only for values between 0 and 90 (p = 0.046). The block application time was lower at a 90° angle (p <0.001), and the satisfaction level decreased as the number of needle entries increased (p<0.001). Patient satisfaction increased as the angle increased (p=0.002)., Conclusion: It was demonstrated that tissue oxygenation increased with NIRS in the extremity subjected to blockade in patients who underwent a USG-guided infraclavicular block at different angles; however, different angles were not observed to affect tissue oxygenation., Key Words: Near-infrared spectroscopy, Tissue oxygen saturation, Ultrasound, Infraclavicular block.

Introduction: Previous studies have demonstrated that thymoquinone has protective effects against ischemia reperfusion injury to various organs like lungs, kidneys and liver in different experimental models., Objective: We aimed to determine whether thymoquinone has favorable effects on lung, renal, heart tissues and oxidative stress in abdominal aorta ischemia-reperfusion injury., Methods: Thirty rats were divided into three groups as sham (n=10), control (n=10) and thymoquinone (TQ) treatment group (n=10). Control and TQ-treatment groups underwent abdominal aorta ischemia for 45 minutes followed by a 120-min period of reperfusion. In the TQ-treatment group, thymoquinone was given 5 minutes. before reperfusion at a dose of 20 mg/kg via an intraperitoneal route. Total antioxidant capacity, total oxidative status (TOS), and oxidative stress index (OSI) in blood serum were measured and lung, kidney, and heart tissue histopathology were evaluated with light microscopy., Results: Total oxidative status and oxidative stress index activity in blood samples were statistically higher in the control group compared to the sham and TQ-treatment groups (P<0.001 for TOS and OSI). Control group injury scores were statistically higher compared to sham and TQ-treatment groups (P<0.001 for all comparisons)., Conclusion: Thymoquinone administered intraperitoneally was effective in reducing oxidative stress and histopathologic injury in an acute abdominal aorta ischemia-reperfusion rat model.
