Abstract
Anesthesia-induced neurotoxicity is a major concern for anesthetists for more than 20 years. Many experimental and clinical studies have been conducted on this topic since late 1990s. However, bibliometric analysis of these papers has not been reported. In this study, we aimed to analyze the 100 most cited articles on anesthesia-induced neurotoxicity. It was planned as cross-sectional study. On January 30, 2023, we searched the "Web of Science (WOS)" database for anesthesia-induced neurotoxicity and most cited 100 papers about this topic were obtained. Data such as authors' names, year of publication, name of the journal, type of paper, and citation numbers were analyzed. The most cited 100 papers were read by the investigators, and the anesthetic, animal type in experimental studies, any protective agent and the method for detecting neurotoxicity used in the studies were also noted. There were 75 articles and 22 reviews in the 100 most cited articles. We found that most of the papers in most cited 100 list were published between 2010 to 1024. Most of the papers (11%) were from Harvard University and almost half of the papers (49%) were published in Anesthesiology. A great number of studies were performed in newborns or early childhood (85.5%) and inhalational anesthetics (54.7%) were the most studied anesthetic type. Most of the most cited 100 papers were published in Q1 journals (P = .012) and the continent of the most journals in this list was America (P = .014). The median total and annual citation numbers of funded papers were statistically significantly higher (P < .001 and P < .001 respectively). Anesthesia-induced neurotoxicity is very important, especially for pediatric anesthetists. This study is the first to conduct a bibliometric analysis of the most cited 100 publications on this field. Although there was a gap in the publications about this topic during COVID-19 pandemic, we believe that there will be many more publications on anesthesia-induced neurotoxicity since the mechanism, outcome and possible protection are still unknown.

Abstract
Axillary nerve blocks are commonly using for forearm and hand surgery. Especially for finger replacement it has been shown continuous plexus blockade improves microcirculation. Addition to that benefit continuous blockade provides adequate analgesia. In this study perfusion index (PI) and plethysmographic variability index (PVI) changes were used to evaluate in blocks success. The PVI and PI values were detected by a Radical-7TM finger pulse oximetry device (Massimo Corp, USA) in both fingers of 50 plastic surgery patients, who received an axillary brachial plexus catheter before surgery. Data recorded at baseline, during catheter replacement, after catheter replacement, and before surgery. All periods hemodynamic data, visual analog scala, Ramsey sedation score and patient satisfaction score were collected. In all 110 patients blocks were successfully applied, PI values in blocked arm increased after local analgesic application (during catheter replacement), (P < .05), PVI values were decreased in the same period but there were no statistical significance. The PI increases after peripheral plexus blockade and may be used as an indicator for successful block placement in awake patient. And also, it may be used as an indicator for catheter effectiveness after surgery. But PVI values cannot detect that kind of relation with nerve blockade.

Abstract
BACKGROUND The aim of this study was to investigate the effects of intracerebroventricularly administered rocuronium bromide on the central nervous system, determine the seizure threshold dose of rocuronium bromide in rats, and investigate the effects of rocuronium on the central nervous system at 1/5, 1/10, and 1/100 dilutions of the determined seizure threshold dose. METHODS A permanent cannula was placed in the lateral cerebral ventricle of the animals. The study was designed in two phases. In the first phase, the seizure threshold dose of rocuronium bromide was determined. In the second phase, Group R 1/5 (n=6), Group 1/10 (n=6), and Group 1/100 (n=6) were formed using doses of 1/5, 1/10, and 1/100, respectively, of the obtained rocuronium bromide seizure threshold dose. RESULTS The rocuronium bromide seizure threshold value was found to be 0.056±0.009μmoL. The seizure threshold, as a function of the body weight of rats, was calculated as 0.286μmoL/kg-1. A dose of 1/5 of the seizure threshold dose primarily caused splayed limbs, posturing, and tremors of the entire body, whereas the dose of 1/10 of the seizure threshold dose caused agitation and shivering. A dose of 1/100 of the seizure threshold dose was associated with decreased locomotor activity. CONCLUSIONS This study showed that rocuronium bromide has dose-related deleterious effects on the central nervous system and can produce dose-dependent excitatory effects and seizures.

Abstract
The nocturnal peak of melatonin can be altered after anesthesia and surgery. We aimed to examine the melatonin levels during the day and night after anesthesia with three commonly used inhalational anesthetics. Forty-eight male Wistar albino rats were randomized into eight groups. Rats were administered anesthesia between 7:00 am and 1:00 pm (day groups) or 7:00 pm and 1:00 am (night groups) for 6 hours. At the end of the anesthesia, blood samples were collected for assessing melatonin levels. Mean values of melatonin levels after 6 hours of anesthesia during daytime were 43.17±12.95 for control, 59.79±27.83 for isoflurane, 50.75±34.28 for sevoflurane and 212.20±49.56 pg/mL for desflurane groups. The night groups' mean melatonin levels were 136.12±33.20 for control, 139.85±56.29 for isoflurane, 117.48±82.39 for sevoflurane and 128.70±44.63 pg/mL for desflurane groups. Desflurane anesthesia between 7:00 am and 1:00 pm significantly increased melatonin levels (p<0.001). Sevoflurane and desflurane anesthesia between 7:00 pm and 1:00 am decreased the melatonin levels but there were no significant differences (p=0.904 and p>0.99, respectively). Isoflurane anesthesia did not significantly change melatonin levels during day or night (p=0.718 and p>0.99, respectively). Our results demonstrate that during daytime desflurane anesthesia can alter melatonin levels. Altered melatonin rhythm following inhalational anesthesia can be related to sleep disorders observed after anesthesia.

Abstract
BACKGROUND During the brain growth spurt, anesthetic drugs can cause cellular and behavioral changes in the developing brain. The aim of this study was to determine the neuroprotective effect of erythropoietin after isoflurane anesthesia in rat pups. METHODS A total of 42, 7-day-old Wistar rats were divided into three groups. Control group (GC; n = 14): Rats breathed 100% oxygen for 6 h; Isoflurane group (GI; n = 14): Rats were exposed to 1.5% isoflurane in 100% oxygen for 6 h; Isoflurane + erythropoietin group (GIE; n = 14): 1000 IU·kg(-1) (intraperitoneal; IP) Erythropoietin was administered after isoflurane anesthesia. Each group was divided into two groups for pathology and learning and memory tests. Silver, caspase-3, and fluoro-jade C staining were used for detecting apoptotic cells in frontal cortex, striatum, hippocampus, thalamus, and amygdala. Morris water maze was used to evaluate learning and memory. RESULTS There was a significant increase in apoptotic cell count after isoflurane anesthesia in the frontal cortex when compared with control group (29.0 ± 9.27 vs 3.28 ± 0.75 [P = 0.002], 20.85 ± 10.94 vs 2.0 ± 0.81 [P = 0.002] and 24.57 ± 10.4 vs 5.14 ± 0.69 [P = 0.024] with silver, caspase-3, and fluoro-jade C staining, respectively). The apoptotic cell count in the frontal cortex was significantly higher in GIE than GC with caspase-3 staining (9.14 ± 3.13 vs 2.0 ± 0.81, P = 0.002). The apoptotic cell count in GIE was significantly reduced in the frontal cortex when compared with GI (4.0 ± 0.81 vs 29.0 ± 9.27 [P = 0.002], 9.14 ± 3.13 vs 20.85 ± 10.94 [P = 0.04] and 4.0 ± 1.63 vs 24.57 ± 10.4 [P = 0.012] with silver, caspase-3, and fluoro-jade C staining, respectively). CONCLUSIONS A total of 1000 IU·kg(-1) IP erythropoietin diminished isoflurane-induced neuroapoptosis. Further experimental studies have to be planned to reveal the optimal dose and timing of erythropoietin before adaptation to clinical practice.

Abstract
BACKGROUND The aim of this study was to identify acute renal injury (ARI) through the use of RIFLE (risk, injury, failure, loss, end-stage kidney disease) criteria and to investigate perioperative risk factors for ARI in liver transplantation (LT). METHODS We reviewed medical records of adult LT patients retrospectively. Postoperative ARI was staged with RIFLE criteria by the 1st and 7th days of the surgery. RESULTS We analyzed 440 adult LT patients, categorized as risk (R), injury (I), or failure (F) according to the RIFLE criteria. In this study, in the first postoperative day, incidence of ARI was 7.95%; all of them were R-class, and, on the 7th day, the incidence of ARI was 7.27%, as R-class 6.59% and I-class 0.68%. Significant risk factors were detected within the first postoperative day including pre-operative hemoglobin levels <9 g/dL (P = .019), intra-operative transfusion of red blood cells (RBCs) (P = .049) and fresh-frozen plasma (FFP) (P = .049), blood loss (P = .011), and post-reperfusion syndrome (P = .023). Multivariate analysis revealed risk factors for ARI as RBCs (odds ratio [OR], 1.049; P = .247) and FFP (OR, 1.017; P = .627) transfusion and blood loss (OR, 1.000; P = .021) (blood loss OR: 0.9996952300184; 95% confidence interval: 0.9994356774026 to 0.999548500399). The only significant risk factor for the 7th postoperative day was the Model for End-Stage Liver Disease (MELD) score (>20) (P = .002). CONCLUSIONS This study showed that RBC and FFP transfusion, perioperative blood loss, and MELD score >20 are risk factors for LT-related ARI. Also normalization of hemoglobin levels with non-blood products in patients with preoperative low hemoglobin levels can diminish the need for RBC and that can prevent ARI.
