“…The RF energy generator's parameters in the cutting mode were a current strength of ≤ 10A, current frequency of 100 kHz, maximum output power of 400 W at a load of 217 Ohm, and vibration range of 0-340 V [7,28,29]. The menisci of the human knee joint, which were removed during total knee arthroplasty and placed in a 0.9% NaCl solution at a temperature of 18°C-21°C during the operation, were placed in an experimental 0.75L container lled with a 0.9% NaCl solution.…”

This study investigates radiofrequency (RF) plasma temperatures around the active electrode of a bipolar arthroscopic RF resector and human knee meniscus tissue temperatures during RF resection. Knee arthroscopy uses various high-frequency (HF) electrodes. However, the electrodes’ configuration leads to the destruction of too much volume and damage to non-target tissue of the knee joint meniscus, potentially leading to repeated damage to the meniscus and post-traumatic arthrosis. Therefore, knowing the optimal parameters for RF meniscus resection, such as resection temperature, mechanical stress on tissues, and process duration, is important. This study experimentally determined the temperature characteristics of RF meniscus resection using a bipolar RF arthroscopic resector and compared the results with a mathematical model of RF meniscus resection compiled in the COMSOL environment. Discrepancies between modelling and experimental research were obtained that determine the optimal temperature parameters for HF resection of the knee joint meniscus: HF plasma temperature, meniscus heating temperature during RF resection using a resector in a conductive fluid, and meniscus heating temperature when using analogues in a conductive fluid.

Das vorliegende Buch wurde im Juli 2018 als Dissertation an der Philosophischen Fakultät der Universität des Saarlandes eingereicht und entstand im Rahmen des DFG-Graduiertenkollegs "Europäische Traumkulturen" (GRK 2021).Meine ersten Begegnungen mit der russischen Literatur und ihrer metaphysischen Dimension fanden in den Lehrveranstaltungen von Frau Univ.-Prof. Dr. Henrieke Stahl statt. Ich danke ihr sehr herzlich dafür, dass sie mir einen ganz neuen Zugang zum literarischen Text eröffnet hat. Ohne ihre jahrelange Betreuung und Unterstützung wäre diese Arbeit nicht möglich gewesen.Meiner Zweitgutachterin Frau Univ.-Prof. Dr. Patricia Oster-Stierle danke ich sehr für die wertvollen Ratschläge, Hinweise und Fragen, die für mich immer eine Bereicherung waren.Den Mitgliedern des DFG-Graduiertenkollegs "Europäische Traumkulturen" danke ich für die Möglichkeit, Anschluss an ein interdisziplinäres Netzwerk erhalten und durch sie neue AutorInnen, Texte und Ansätze kennengelernt zu haben. Insbesondere möchte ich Ramona Weber dafür danken, dass sie immer ein offenes Ohr für mich hatte und mir immer mit Rat und Tat zur Seite stand.Für das gewissenhafte Lektorat bin ich Herrn Dr. Christian Quintes und Herrn PD Dr. Nikolas Immer sehr dankbar. Katharina Kraus und Robert Lemle gebührt ein besonderer Dank für die Hilfe bei der Formatierung und den Korrekturen.Ich bin sehr froh, derzeitig an der DFG-Kollegforschungsgruppe "Russischsprachige Lyrik in Transition. Poetische Formen des Umgangs mit Grenzen der Gattung, Sprache, Kultur und Gesellschaft zwischen Europa, Asien und Amerika" mitwirken zu dürfen. Ich bedanke mich bei Frau Professor Stahl für die Möglichkeit, dass diese Dissertation im Rahmen der Buchreihe "Neuere Lyrik. Interkulturelle und interdisziplinäre Studien" erscheinen kann.Und zuletzt danke ich meiner Familie, die immer hinter mir steht. Meinen Eltern und meiner Schwester ist dieses Buch gewidmet.

“…Coblation is operated at surface temperatures (40-70°C) much lower than those of more traditional techniques [7]. Instead of relying on heat, coblation applies radiofrequency energy to a conductive natural salt solution, forming a plasma membrane comprised of highly ionized particles that hold enough energy to break the molecular bonds holding the tissue, thereby safely removing the target tissue [7][8][9]. The use of coblation eliminates the risk of causing thermal damage that comes with heat and minimizes necrosis of surrounding healthy tissue, therefore resulting in minimal pain and faster recovery [8,9].…”

This study aimed to compare the outcomes of coblation versus bipolar diathermy in pediatric patients undergoing tonsillectomy. A systematic review and meta-analysis were performed per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Guidelines. An electronic search of information was conducted to identify all Randomized Controlled Trials (RCTs) comparing the outcomes of coblation versus bipolar in pediatric patients undergoing tonsillectomy. Primary outcome measures were intraoperative bleeding, reactionary hemorrhage, delayed hemorrhage, and post-operative pain. Secondary outcome measures included a return to a normal diet, effects on the tonsillar bed, operation time, and administration of analgesia. Fixed and random-effects models were used for the analysis. Seven studies enrolling 1328 patients were identified. There was a significant difference between coblation and bipolar groups in terms of delayed hemorrhage (Odds Ratio [OR] = 0.27, P = 0.005) and post-operative pain (standardized mean difference [MD] = -2.13, P = 0.0007). Intraoperative bleeding (MD = -43.26, P = 0.11) and reactionary hemorrhage did not show any significant difference. The coblation group improved analgesia administration, diet and tonsillar tissue recovery, and thermal damage for secondary outcomes. No significant difference was reported in terms of operation time. In conclusion, coblation is comparable to a bipolar technique for pediatric patients undergoing tonsillectomy. It improves postoperative pain and delayed hemorrhage and does not worsen intraoperative bleeding and reactionary hemorrhage.
