    An analysis of scientific activities in the first year of the COVID-19 pandemic
    (Sivas Cumhuriyet University, 2021) Baş, Koray; Yılmaz, Fulya
    Objective: COVID-19, a contagious disease which is caused by novel coronavirus (SARS-CoV-2), is still spreading globally. Bibliometric analyses assess the current status and trends in a spesific research domain by using several (Scopus, PubMed, Web of Science) databases. The aim of present study is to evaluate the scientific activities in the first year of the COVID-19 pandemic on scientific output.Method: Web of Science software was used for the search and the analysis. All scientific papers published about COVID-19 included in Science Citation Index Expanded (SCI-E) from January 1st to December 13th 2020; the date of the study, were searched by using the terms of “COVID-19”, “2019-n-CoV”, “SARS-CoV-2”, “Coronavirus disease 19” and “2019 novel coronavirus” as scientific nomenclatures of COVID-19 in the topic search section of the software.Results:Overall; 47368 scientific papers related to COVID-19, indexed by SCI-E, were found related to COVID-19 between January 1, 2020 to December 13, 2020. The biggest contribution for publications was from United States of America, the most of the publications was articles, the authors that contribute to the literature ≥ 150 papers were all from China and the journal that published the most paper was British Medical Journal.Conclusions: The present analyse reports an overview of the literature on COVID-19 since the beginning. These kind of periodic analysis provides interesting insights regarding the past and progress of each area of scientific knowledge and also can guide the rethinking of scientific data.

    Restenosis rates after carotid endarterectomy with primary closure under regional anesthesia: results of a single center study with 553 patients
    (2021) Baş, Koray; Erdinç, İbrahim; Yılmaz, Fulya
    Objectives: Carotid endarterectomy (CEA) is the current gold standard management for carotid artery stenosis but there is still a debate on which closure technique is superior to lower postoperative restenosis rates. The aim of this retrospective study is to assess “restenosis rates” of our 553 patients who underwent CEA “under regional anesthesia” with “primary closure” technique. Materials and Methods: We retrospectively evaluated patients who underwent CEA, by non-shunting technique under regional anesthesia, with primary longitudinal arteriotomy closure between 2008 and 2019. Results: Five hundred and fifty three patients (409 male and 144 female) were evaluated. There were no statistically significant differences in terms of demographic characteristics, sides of stenosis, operation time, preoperative stenosis ratio, and postoperative hospital stay between the gender groups. None of the patients developed restenosis (stenosis rate of over 50%) after primary closure under regional anesthesia during the two-year follow-up period. Conclusion: According to our results, CEA with “primary closure under regional anesthesia” is a safe and effective surgical treatment for carotid stenosis without postoperative restenosis. We thought that further studies, which investigate the rate of restenosis after CEA, should also evaluate the “type of the anesthesia management” as a factor on it.

    Tracheal cuff rupture during conventional total thyroidectomy: an unusual complication
    (Springer India, 2022) Yiımaz, Fulya; Baş, Koray; Deniz, Oğuzhan; Damar, Nagihan
    One of the most common surgical procedures performed worldwide is thyroidectomy. Although thyroid surgery is generally accepted as a safe surgery, its complications are still not uncommon. But a tracheal cuff rupture during conventional total thyroidectomy due to a surgical needle injury is a very unusual complication. In this report, we present uneventful anesthesia management of a case without re-intubation whose endotracheal tube cuff was ruptured during conventional total thyroidectomy due to surgical needle injury. Two hours and 15 min after commencing the operation, the tidal volume decreased abruptly and we detected that the pilot balloon of the endotracheal tube was collapsed. A surgical team was informed, and they stated that the endotracheal tube cuff may be damaged with a surgical needle injury during a particular step of the operation. Anesthesia was maintained with increased oxygen flow and increased fractional inspired oxygen without reintubation. After extubation, the rupture of the endotracheal tube cuff was confirmed by concomitant deflation of endotracheal tube cuff during the inflation of the pilot balloon and observing air bubbles from a laceration on the upper part of the balloon in water. An attentive communication between surgery and anesthesia team members is crucial for better outcomes, especially in case of unusual situations.
