Item Supra-Inguinal Fascia Iliaca Block in Older-Old Patients for Hip Fractures: A Retrospective Study(2023) Bali, Cagla; Ozmete, Ozlem; 34582902Background Pain management in hip fracture patients is of great importance for reducing postoperative morbidity and mortality. Multimodal techniques, including peripheral nerve blocks, are preferred for postoperative analgesia. Older-old hip fracture patients with high ASA scores are highly sensitive to the side effects of NSAIDs and opioids. Our aim was to investigate the effectiveness of the recently popularized Supra-Inguinal Fascia Iliaca Block (SIFIB) in this population.Methods Forty-one ASA III...IV patients who underwent SIFIB...+...PCA (G-SIFIB) or PCA alone (Group Control: GC) after general anesthesia were evaluated retrospectively. In addition to 24-hour opioid consumption, Visual Analog Scale (VAS) scores, opioid-related side effects, block-related complications, and length of hospital stay were compared.Results Twenty-two patients in G-SIFIB and 19 patients in GC were evaluated. The postoperative 24-hour opioid consumption was lower in G-SIFIB than in GC (p<0.001). There was a statistically significant reduction in VAS scores at the postoperative 1(st), 3(rd), and 6(th) hours at rest (p<0.001) and during movement (p<0.001 for the 1(st) and 3(rd) hours, and p=0.02 for the 6(th) hour) in G-SIFIB compared to GC. There was no difference in pain scores at the 12(th) and 24(th) hours postoperatively. While there was no difference between the groups in terms of other side effects, respiratory depression was significantly higher in GC than in G-SIFIB (p=0.01).Conclusion The SIFIB technique has a significant opioid-sparing effect and thus reduces opioid-related side effects in the first 24 hours after hip fracture surgery in older-old patients.Item Relationship Between Perioperative Factors and Splenic Artery Steal Syndrome After Orthotopic Liver Transplant: A Retrospective Clinical Study(2023) Kuscu, Ozlem Ozkan; Kus, Murat; Incekas, Caner; Ozmete, Ozlem; Ergenoglu, Pinar; Yildirim, Sedat; Torgay, Adnan; Haberal, Mehmet; 37885290Objectives: After orthotopic liver transplant, ischemia of biliary tract and graft loss may occur due to impaired hepatic arterial blood flow. This situation with hypersplenism and impaired hepatic arterial blood flow is defined as splenic artery steal syndrome. The aim of this study was to investigate the relationship between perioperative factors and splenic artery steal syndrome in orthotopic liver transplant patients. Materials and Methods: Forty-five patients who underwent orthotopic liver transplant between 2014 and 2022 were included in the study. The data for the patients were obtained from the hospital database, including the intraoperative anesthesiology and postoperative intensive care records. Results: Eleven patients were diagnosed with splenic artery steal syndrome. Patients with splenic artery steal syndrome had higher need for intraoperative vasopressor agents (P = .016) and exhibited lower intraoperative urine output (P = .031). In the postoperative intensive care follow-up, patients with splenic artery steal syndrome had higher levels of C-reactive protein during the first 48 hours (P = .030). Conclusions: Intraoperative administration of vasopressor drugs, low urine output, and early postoperative high C-reactive protein levels were associated with the development of splenic artery steal syndrome in patients undergoing orthotopic liver transplant. Future studies should focus on investigation of biomarkers associated systemic hypoperfusion that may contribute to the development of splenic artery steal syndrome.Item Scientific Publication Performance of the Erector Spinae Plane Block in Turkiye: A Bibliometric Analysis(2023) Catalca, Sibel; Ozmete, Ozlem; Ozyilkan, Nesrin Bozdogan; 38149368Objective: Erector spina plane block (ESPB) was first described in 2016 and is effective in various surgical procedures. Bibliometric analysis is a novel method that evaluates the contribution of scientific studies conducted in a specific field on the existing literature. This study examined articles on ESPB published by anaesthesia clinics in Turkiye in journals under the Science Citation Index Expanded (SCI-E) category. Methods: Studies on ESPB indexed in the Web of Science Core Collection and published in Turkiye from 2018 to 2022 were evaluated. The primary outcome was to determine the number of studies published in journals under the SCI-E category. The secondary aims were to determine the number of citations and the institutions where the studies were conducted. Results: A total of 159 publications were analyzed. The journal with the highest number of publications was "Journal of Clinical Anesthesia" (n = 70). The institution that has to date made the most contributions to the literature was Ataturk University (n = 31). The most cited article was "Ultrasound guided erector spinae plane block reduces postoperative opioid consumption following breast surgery: A randomized controlled study." published by Gurkan et al. (n = 175). Conclusion: This study reflects the contribution level of Turkiye-addressed anaesthesia clinics to journals under the SCI-E category. Our findings can serve as a benchmark for attracting the attention of national and international researchers.Item The Impact of Multimodal Analgesia Timing on Postoperative Pain in Cesarean Delivery. A Prospective Randomized Study(2023) Ozmete, Ozlem; Sener, Mesut; Bali, Cagla; Caligan, Esla; Durdag, Gulsen Dorgan; Aribogan, Anis; 38131366AIM: The issue of preemptive or preventive use of paracetamol still raises questions in terms of multimodal analgesia in cesarean delivery. A combination of paracetamol and opioid is commonly used for pain management after cesarean delivery. This study aims to compare postoperative pain level and analgesic consumption when using paracetamol at two different perioperative times in cesarean section. MATERIAL AND METHODS: Sixty patients recruited for elective cesarean section under general anesthesia were included in this prospective study. Patients were randomly assigned to receive iv 1 g paracetamol 15 minutes before incision (Group PE) or after delivery of newborn (Group PV). Visual analog scale (VAS) values, 24-hour morphine consumption, additional analgesic requirement, side effects, and patient and surgeons' satisfaction were recorded. RESULTS: Demographic data and hemodynamic values of the patients were similar in both groups. There was no differences between groups in terms of VAS scores at rest and during movement, additional analgesic requirement during the postoperative 1st hour, and 24-hour total morphine consumption. There was no difference in side effects, and patient and surgeon satisfaction scores postoperatively. CONCLUSIONS: Preemptive and preventive use of paracetamol provides the same quality of analgesia and opioid sparing effect without increasing the frequency of adverse effects.Item Reversal of Rocuronium Induced Neuromuscular Block with Sugammadex in Patients Under 2 Years of Age. A Series of 280 Cases(2023) Ozmete, Ozlem; Dardag, Emre; Civi, Soner; 38131376AIM: Neuromuscular muscle relaxants are still indispensable for surgical procedures requiring general anesthesia, and the use of these agents may result in postoperative residual curarization. Sugammadex may offer a distinct advantage to pediatric patients where residual neuromuscular blockade may be poorly tolerated. Sugammadex is approved for use in adults and children over two years. This is the main reason why large-scale studies could not be conducted in the group of patients younger than two years old. This study aimed to evaluate the efficacy and safety of sugammadex for reversing deep rocuronium-induced neuromuscular blockade in children under two years of age. METHODS: Pediatric patients younger than two years of age who underwent neurosurgery under sevoflurane anesthesia were included in the study. Neuromuscular block was achieved by the administration of rocuronium. It was antagonized by the administration of 5 mg/kg sugammadex and evaluated using train-of-four (TOF). Primary outcome measure was the time from sugammadex administration to return of the TOF ratio to 0,9. Postoperative adverse events were also recorded. RESULTS: Two hundred eighty patients (10 day-24 months of age; 3-18 kg) were included in this study. Reversal of deep rocuronium-induced neuromuscular block with sugammadex was rapid in all patients. No residual curarization or recurarization was observed. No adverse events or hypersensitivity reactions were observed after administration of sugammadex. CONCLUSION: Reversal of rocuronium-induced deep neuromuscular block in infants was rapid and safe. Sugammadex provided safe extubation in patients younger than two years of age who had undergone neurosurgery.

Design: Prospective, randomized, double-blind, placebo-controlled clinical trial. Setting: University Teaching Hospital. Patients: American Society of Anesthesiologists (ASA) I and II 60 patients between 18-40 years of age who were scheduled to undergo elective cesarean section. Interventions: Patients were randomized into two groups to receive either intravenous 1 g paracetamol (100 mL) (Group P) or 0.9% NaCl solution (100 mL) (Group C) 15 minutes before the induction of general anesthesia. After delivery of newborn 0.15 mg kg(-1) morphine was administered to all patients in both groups. Postoperative analgesia was provided with patient-controlled intravenous analgesia with morphine in the postoperative period. Measurements: Pain which is the primary outcome measure was assessed at 15th, 30th minutes and 1st, 2nd, 4th, 6th, 12th, 24th hours by the Visual Analogue Scale. Patients' demographics, hemodynamics, Apgar score, additional analgesic requirement, side effects, patients' satisfaction and postoperative total morphine consumption within 24 hours were recorded. Main Results: Median visual analogue scale for pain in Group P was significantly lower compared to Group C at all time points except for the score at 24th h postoperatively (P <.05). Additional analgesic requirement during postoperative first hour was lower in Group P (P <.05). Total morphine consumption was higher in Group C compared with Group P (P <.05). There was no difference between groups with respect to Apgar scores, side effects, and patient satisfaction (P >.05). Conclusions: Preoperative use of single-dose intravenous 1 g paracetamol was found to be effective in reducing the severity of pain and opioid requirements within 24 hours after cesarean section.

Evren; Hersekli, Murat A.; Aribogan, Anis; 0000-0002-7901-0185; 0000-0003-2615-1918; 0000-0001-5845-699X; 0000-0002-4419-5693; 27871565; AAW-9940-2021; AAI-8769-2021; AAI-8790-2021; AAI-7779-2021; S-8336-2019Study objective: This study evaluated the postoperative analgesic efficacies of fascia iliaca block and periarticular drug injection techniques after TKA (total knee arthroplasty) surgeries. Design: Prospective, randomized clinical trial. Setting: University Teaching and Research Center. Patients: Seventy-one American Society of Anesthesiologists (ASA) I-III patients between 48 and 70 years of age who underwent total knee arthroplasty were randomized. Interventions: Tenoxicam (20 mg) was administered intramuscularly to both groups of patients 30 minutes before surgery. Patients were randomized into two groups to receive fascia iliaca block before the induction of anesthesia (Group FI) or periarticular drug injection during the surgery (Group PI). All surgeries were performed under general anesthesia using standard techniques. Postoperative analgesia was provided with patient-controlled intravenous morphine. Measurements: Total morphine consumption was the primary outcome measure and was recorded postoperatively at 1, 2, 6,12 and 24 hours. Pain levels at rest and on movement (knee flexion) were evaluated using the Visual Analogue Scale (VAS) and recorded at the same time points. Patients' demographics, rescue analgesic demands, side effects, hemodynamics, and satisfaction scores were also recorded. Main results: The groups had similar VAS scores both at rest and on movement (P > .05). However, the amount of cumulative morphine and use at each follow-up period was higher in Group PI (P < .0001). The groups did not differ significantly in rescue analgesic use or side effects, such as nausea/vomiting, hemodynamic variables, and patient satisfaction scores (P > .05). Conclusions: Fascia iliaca block may be used as an alternative method to periarticular injection, and it effectively reduces the amount of morphine used to relieve post-TKA pain.

The aim of this study was to investigate the protective effects of curcumin on a rat model of carbapenemresistant Escherichia coli-induced acute lung injury (ALI). Thirty-two rats were randomly allocated to 4 groups to induce an ALI: negative control group (rats not infected with E coli with no antibiotic treatment), positive control group (rats infected with E coli with no antibiotic treatment), imipenem group (rats infected with E coli that received intraperitoneal injection of imipenem), and the imipenem+curcumin group (rats infected with E coli that received intraperitoneal injection of imipenem and were fed on curcumin). The rats were killed, and lung tissues samples were harvested for biochemical analyses and histopathologic examination. Total antioxidant status (TAS), total oxidant status (TOS), tumor necrosis factor alpha (TNF alpha), and interleukin-6 (IL6) were measured. TOS increased in the positive control group (P < 0.001) and decreased in the imipenem and imipenem+curcumin groups (P < 0.001 and P < 0.001, respectively). TAS decreased in the positive control group (P = 0.005). Imipenem treatment did not increase TAS, but the imipenem+curcumin group increased TAS (P = 0.014). TNF alpha and IL6 increased in the positive control group compared with the negative control group (P < 0.001 and P = 0.010, respectively). Imipenem decreased TNF alpha (P < 0.001), but did not decrease IL6 (P = 0.418). Imipenem+curcumin decreased TNF alpha (P < 0.001); this decrease was more pronounced compared with the imipenem group (P = 0.008). IL6 decreased in the curcumin group compared with the positive control group (P = 0.011). Curcumin combined with imipenem can be an alternative therapeutic agent to overcome the resistance of E coli strains.Item Sugammadex Given for Rocuronium-Induced Neuromuscular Blockade in Infants: A Retrospective Study(2016) Ozmete, Ozlem; Bali, Cagla; Cok, Oya Yalcin; Turk, Hatice Evren Eker; Ozyilkan, Nesrin Bozdogan; Civi, Soner; Aribogan, Anis; 0000-0002-1055-5152; 0000-0003-3004-2626; 0000-0002-7901-0185; 0000-0002-4973-8132; 0000-0003-2615-1918; 0000-0002-4419-5693; 0000-0001-5845-699X; 27871583; AAI-7779-2021; U-2400-2018; AAI-7998-2021; AAI-8790-2021; AAI-8769-2021; S-8336-2019; AAI-7880-2021Study Objective: To evaluate the efficacy and safety of sugammadex in reversing profound neuromuscular block induced by rocuronium in infant patients. Design: Retrospective observational study. Setting: University teaching hospital. Patients: Twenty-six infants (2-12 months of age; 3-11 kg) with an American Society of Anesthesiologists classification I, II, or III who were scheduled to undergo neurosurgical procedures were included in the study. Interventions: Anesthesia was induced with 5 mg/kg thiopental, 1 mu g/kg fentanyl and 0.6 mg/kg rocuronium. Sevoflurane was administered to all patients after intubation. Methods: The neuromuscular block was monitored with acceleromyography using train-of-four (TOF) stimuli. Patients received additional doses of rocuronium to maintain a deep block during surgery. If profound neuromuscular block (TOF, 0) persisted at the end of the surgery, 3 mg/kg sugammadex was administered. Measurements: The demographic data, surgeries, and anesthetic agents were recorded. The time from sugammadex administration to recovery of neuromuscular function (TOF ratio, >0.9) and complications during and after extubation were also recorded. Main results: Twenty-six infants who had a deep neuromuscular block (TOF, 0) at the end of surgery received 3 mg/kg sugammadex. The mean recovery time of the T4/T1 ratio of 0.9 was 112 seconds. No clinical evidence of recurarization or residual curarization was observed. Conclusions: The efficacy and safety of sugammadex were confirmed in infant surgical patients for reversal of deep neuromuscular block induced by rocuronium. (C) 2016 Elsevier Inc.

Aim of this study is to investigate the contribution of laparoscopy in predicting 'no gross residue' in advanced stage ovarian cancer. Methods Data of advanced stage ovarian cancer patients, who underwent diagnostic laparoscopy for prediction of complete cytoreduction due to an alternative model, are analyzed retrospectively. Accordingly, in the absence of obvious mesenteric retraction or extensive tumoral implants on small intestine in laparoscopic assessment, cases were deemed surgically resectable, and the operation was continued with laparotomy to achieve complete cytoreduction. Clinical features of the patients, surgical details, complete and optimal cytoreduction rates, and perioperative complications were evaluated. Results Out of 243 patients with advanced stage ovarian/tubal/peritoneal cancer, laparoscopy was performed at 93 patients, 77 of whom underwent primary cytoreduction subsequently. Complete cytoreduction (no gross residue) and optimal cytoreduction (< 1 cm residual tumor) rates were 75.3 and 100%, respectively. None of the patients had suboptimal surgery. Morbidity and mortality rates were acceptable. Conclusion Laparoscopic evaluation prior to cytoreductive surgery can highly contribute to prediction of complete or optimal cytoreduction in suitable patients. However, experience and skills of the surgeon, as well as technical equipment of the center, may affect surgery; therefore, the model to predict residual tumor should be individualized according to the set up and the surgical team of each center.
