Article Comparative Sedation With Sevoflurane and Thiopental in Children Undergoing Mr Imaging(Coll Physicians & Surgeons Pakistan, 2022) Kurt, Nurettin; Caliskan, Duygu Karakose; Gunes, Haci YusufObjective: To compare the use of propofol and thiopental in children undergoing MRI. Study Design: Descriptive, comparative study. Place and Duration of Study: University of Health Sciences, Van Training and Research Hospital, Van, Turkey, between January 01 and December 31, 2019. Methodology: One thousand two hundred and twenty two paediatric patients having MRI were included and divided into two groups. Patients aged 2-18 years who were administered Propofol were classified as Group I, and the patients under the age of 2 years who were administered Thiopental were classified as group II. All patients received Sevoflurane insufflation via face mask after induction agent. Patient's demographic data, ASA scores, anaesthesia-procedure-recovery times, comorbidities, type of MRI examination and complications were recorded. Results: Age, body weight and ASA score of the patients in Group I were higher than Group II (p<0.05). Epilepsy, cerebral palsy, mental retardation, speech retardation and autism were more prevalent in Group I than in Group II (p< 0.05). Neuromuscular growth retardation, hydrocephalus, and metabolic disease were less common in Group I than in Group II (p<0.05). With this Apnea and desaturation was higher in Group I, and bradycardia was higher in Group II. Conclusion: Sevoflurane insufflation with a face mask can be safely used in children after induction of anaesthesia with propofol or thiopental.Article The Differences in Cerebral Oxygenation Among Patients Undergoing Thyroidectomy in Different Positions and Comparison of Their Effects on Nausea-Vomiting(Drunpp-sarajevo, 2012) Gunes, Haci Yusuf; Goktas, Ugur; Kati, Ismail; Yuce, Hasan Husnu; Bartin, SerapBackground: Hyperextension of the patient's neck associated with distortion and vasospasm of the vertebral and internal carotid arteries intra-operatively. In this study we aimed to investigation of whether there is effects of supine, slight neck hyperextension and semi-seated and neck hyperextension positions of patients on postoperative nausea and vomiting (PONV) via regional cerebral oxygen saturation (rSO(2)). Methods: ASA I-II group of 40 adult patients for whom elective thyroid operations under general anesthesia (GA) were planned, were divided into 2 randomized groups. The patients in the Group 1 were positioned in the hyperextension of the neck at 45 degrees semi-seated position and in the Group 2 patients were positioned in the supine position. Results: The heart rate (HR), and mean arterial pressure (MAP) values were found to be statistically significantly higher in the first group than the second group in a few values (p<0.05). There were no significant differences between the groups when they were compared for left and right cerebral oxygen saturation (p>0.05). No correlation was determined between the cerebral arterial desaturation and rates of PONV. Conclusions: It was concluded that cardiovascular changes due to hyperextension of the neck in a semi-seated position during surgery under general anesthesia, despite a cerebral desaturation in rSO(2) that remained within the cerebral auto-regulation range and there is no correlation of PONV with either neck hyperextension in the semi-seated position or desaturation conditions with less than a 20% decrease in rSO(2).Article The Effects of Low Flow and Normal Flow Desflurane Anesthesia on Liver and Renal Functions and Serum Cystatin C Levels in Geriatric Patients: a Prospective Randomized Controlled Study(Gunes Kitabevi Ltd Sti, 2023) Kol, Afife Guler; Gunes, Haci YusufIntroduction: Aging is a physiological process and the elderly population is increasing. In parallel to the increasing of the elderly population, the number of geriatric patients who required an invasive procedure or surgical intervention under anesthesia are also increasing. The geriatric patients who are frailty and have a loss of functional reserve in all organ systems are more sensitive to anesthetic agents. The purpose of this research was to investigate whether low flow desflurane anesthesia also affects hepatic and kidney functions, in elderly patients. Methods: After approval from the local ethics committee, the patients were divided into two groups; as the low flow desflurane anesthesia group and the normal flow desflurane anesthesia group using the closed-envelope method. Calibration and leakage tests of the anesthesia device (Primus, Drager) were performed before anesthesia. Heamodynamics parametres, peripheral oxygen saturation, and bispectral index monitoring were performed to all patients in operating room. The blood samples were collected before anesthesia induction, after surgery, and at the postoperative 24th hour. The serum alanine aminotransferase and aspartate aminotransferase levels were measured to assess the liver damage. The serum creatinine, blood urea nitrogen, and cystatin C levels were measured to assess the kidney function. Results: The serum alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and cystatin C levels and hemodynamic parameters, peripheral oxygen saturation and bispectral index values were similar in both groups. Conclusions: It was concluded that low-flow desflurane anesthesia does not adversely affect liver and kidney functions in geriatric patients and is as safe as normal-flow desflurane anesthesia.Article The Effects of Preincisional Levobupivacaine Infiltration on Extubation Comfort, Postoperative Recovery and Visual Analogue Scale in Appendectomy Patients(Aves, 2015) Gunes, Haci Yusuf; Cegin, Muhammed BilalObjective: The aim of our study was to determine the effect of preincisional 0.25% levobupivacaine infiltration on extubation comfort, postoperative recovery and visual analogue scale (VAS) in appendectomy patients. Methods: Forty 15-60-year-old patients at American Society of Anaesthesiologists (ASA) physical status I-II, scheduled for appendectomy were included in the study. After routine monitorisation, anaesthesia induction was performed with propofol, fentanyl and rocuronium; later, maintenance was continued with sevoflurane. Patients were divided into two groups randomly. A total 20 mL of 0.25% (50 mg) levobupivacaine was injected around the incision line as a rectangle in Group 1. Levobupivacaine was not administered in Group 2 patients. Heart rate, peripheral oxygen saturation, additional fentanyl requirement and mean blood pressure were recorded during the operation. All patients were evaluated according to difficulties encountered during extubation Results: Discharge time, necessity of diclofenac and postoperative VAS values at 0-1 hours were statistically lower in Group 1 patients than the Group 2 patients (p<0.05). Difficulties, like straining, cough, laryngo-bronchospasm, vomiting and nausea during extubation, were 5% and 25% in Group 1 and Group 2, respectively, but these differences were not statistically significant (p=0.077). Conclusion: Infiltration of 0.25% of levobupivacaine as a rectangle which included the incision line before surgery decreases discharge time, provides analgesia well in the early postoperative period and diminishes the requirement of analgesics in appendectomy patients.Article Impact of Covid-19 Pandemic on the Circadian Rhythm of Cesarean Section Deliveries(Lippincott Williams & Wilkins, 2024) Gunes, Haci Yusuf; Keskin, Mehmet EminCircadian rhythms synchronize all biological functions, enabling humans to foresee and respond better to periodic environmental changes. The coronavirus disease (COVID-19) lockdown regulations significantly changed the lighting conditions in pregnant women, leading to chronological disruption. This study aimed to investigate the impact of the COVID-19 on the circadian rhythm of cesarean deliveries. We investigated whether the circadian rhythm of cesarean section deliveries changed during the first year of the COVID-19 pandemic at a tertiary hospital in Van Province, eastern Turkey. We analyzed the distribution of birth times for 1476 cesarean deliveries performed between March 01, 2020 and January 20, 2021 (1st year of the COVID-19 pandemic) and compared this information with data from 1194 cesarean deliveries performed during a similar period in the previous year. The primary outcome was the change in the circadian rhythm of cesarean deliveries. Secondary outcomes included cesarean section (CS) delivery rates, indications for CS, 1st and 5th minutes Appearance (skin color), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), and Respiration scores, and anesthesia technique use rates. Regarding the time distribution of CS deliveries in the first year of the COVID-19 pandemic, the maximum number of cesarean deliveries (n = 234, 16%) occurred between 14:00 and 16:00 (P = .112). Cesarean deliveries in pre-COVID-19 group were most frequently performed between 10:00 and 12:00, at a rate of 18% (n = 216) (P = .001). In both groups, the time point at which CS deliveries were the least performed was 04:00 to 06:00, and the rates were different (n = 35, 2% and n = 14, 1%, respectively) (P = .022). A 4-hour phase shift was detected at the peak of the birth time in the first year of the COVID-19 pandemic compared to the previous year. These results suggest that the circadian rhythm of cesarean deliveries is affected by the pandemic.
