During the procedure, one-lung ventilation using double-lumen tubes or bronchial blockers is employed as needed. For postoperative pain control, a multimodal approach is taken, incorporating options such as thoracic epidural anesthesia, paravertebral blocks, intercostal nerve blocks, and intravenous patient-controlled analgesia (IV-PCA). These practices have remained consistent in recent years. However, anesthetics and anesthesia-related devices including physiological monitors and ultrasound machines have continued to evolve. As a result, anesthesia today differs significantly from that of a decade ago. This section highlights the latest advances in anesthetics and anesthesia-related technologies, including: (1) the use of artificial intelligence (AI) for monitoring and decision support, (2) robotic anesthesia systems with automated drug delivery, (3) remimazolam as a novel ultra-short-acting sedative, and (4) autologous blood recovery systems capable of platelet collection, improving hemostasis and reducing transfusion requirements.

{"title":"[Ablation Treatment for Peripheral Lung Cancers].","authors":"Yoshikane Yamauchi, Yukinori Sakao","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Ablation therapy is a minimally invasive local treatment that destroys tumor tissue. It has attracted attention as a treatment option for early-stage lung cancer and metastatic lung tumors. In this review, we provide an overview of the current status of treatment, technical characteristics, indications, and treatment results for three ablation methods for peripheral lung lesions: radiofrequency ablation (RFA), microwave ablation (MWA), and cryoablation (PCT). RFA is relatively simple to perform, but its therapeutic effect is limited in tumors near blood vessels due to the influence of heat diffusion by blood vessels and bronchi. MWA enables wide-range ablation in a short time compared to RFA and has the advantage of being less affected by blood vessels and bronchi. PCT enables easy confirmation of the ablation range because it can be visualized as an ice ball on computed tomography (CT) fluoroscopy and is less painful for the patient. It is characterized by the induction of tumor cell death by apoptosis and the preservation of tissue structure. The indications for ablation therapy are mainly early-stage non-small cell lung cancer (NSCLC) that is difficult to surgically resect. Patients with high surgical risk, such as elderly patients and patients with serious complications, are targeted. The combination of ablation therapy and immunotherapy is expected to have a therapeutic effect, and systemic antitumor effects through the release of tumor-associated antigens can be expected. In the future, further expansion of treatment options for lung cancer is expected with the development of optimal combination methods with immunotherapy and the development of transbronchial approaches.</p>","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

Traditional cut-and-sew techniques, while effective, pose risks such as bleeding and prolonged operative time. Modern surgical ablation devices-such as cryoablation, radiofrequency, microwave, and ultrasound-enable targeted, transmural myocardial necrosis with greater safety and efficiency. However, improper use or incomplete ablation may lead to residual conduction, resulting in arrhythmia recurrence or new arrhythmogenic circuits. Each device has distinct energy sources, thermal profiles, and tissue interactions. Cryoablation, for example, remains reliable with minimal collateral damage, while bipolar radiofrequency allows precise, real-time monitoring of lesion transmurality. Ultrasound and microwave technologies offer deeper tissue penetration but have varying long-term efficacy. Thorough understanding of device characteristics, lesion depth, and intraoperative confirmation of conduction block is essential. As minimally invasive techniques advance, the role of appropriately selected and applied ablation devices becomes increasingly vital for safe and effective arrhythmia surgery.</p>","PeriodicalId":17841,"journal":{"name":"Kyobu geka.
