Background: The aim of this study was to compare the streamlined liner of the pharynx airway (SLIPA) with the classic laryngeal mask airway when used by novice personnel. Methods: There were 114 patients enrolled into this study who underwent general anesthesia were randomly allocated into one of 2 groups; LMA group (n = 57) or SLIPA group (n = 57). After insertion, insertion success rate, insertion time, and hemodynamic responses to insertion were accessed. After surgery, postoperative airway m

Vertebroplasty (VP) can effectively treat pain and immobility caused by vertebral compression fracture. Because of complications such as extravasation of bone cement (polymethylmethacrylate, PMMA) and adjacent vertebral fractures, some practitioners prefer to inject a small volume of PMMA. In that case, however, insufficient augmentation or a subsequent refracture of the treated vertebrae can occur. A 65-year-old woman visited our clinic complaining of unrelieved severe low back and bilateral fl

Surgical pleth index (SPI) monitoring is a representative, objective nociception-monitoring device that measures nociception using photoplethysmographic signals. It is easy to apply to patients and the numerical calculation formula is intuitively easy to understand; therefore, its clinical interpretation is simple. Several studies have demonstrated its efficacy and utility. Compared with hemodynamic parameters, the SPI can detect the degree of nociception during surgery under general anesthesia

Due to unknown safety concerns, sugammadex should not be administered to patients with end-stage renal disease (ESRD). However, because the supply of benzylisoquinolinium-type neuromuscular blocking agents (NMBAs) has been discontinued, rocuronium is the only non-depolarizing NMBA that can be used in clinical settings in some countries, including South Korea. The administration of sugammadex cannot be avoided to achieve rapid and complete neuromuscular recovery in patients with ESRD or renal tra

Background: Endoscopic submucosal dissection has become popular. However, this can cause serious complications. In this case, esophageal perforation caused bilateral tension pneumothorax.Case: A 60-year-old man with esophageal adenoma underwent endoscopic submucosal dissection under general anesthesia. The peak airway pressure was 25 cmH2O after induction but abruptly increased to 40 cmH2O after 30 min. Respiratory sounds were barely heard. The lack of lung sliding in either (right-dominant) lun

Effective perioperative pain control is essential for patient comfort and for optimizing surgical outcomes and the quality of recovery. Multimodal analgesic strategies have become a cornerstone of modern perioperative pain management. Although regional analgesia is widely used within this framework, the clinical utility of conventional local anesthetics remains limited by their relatively short duration of action. Continuous infusion techniques can sustain local anesthetic delivery; however, cat

Background: Chronic glucocorticoid exposure is associated with resistance to nondepolarizing neuromuscular blocking agents. Therefore, we hypothesized that sugammadex-induced recovery would occur more rapidly in subjects exposed to chronic dexamethasone compared to those who were not exposed. This study evaluated the sugammadex-induced recovery profile after neuromuscular blockade (NMB) in rats exposed to chronic dexamethasone.Methods: Sprague–Dawley rats were allocated to three groups (dexameth

Background: Grip strength (GS), an indicator of sarcopenia, declines with age and is associated with frailty, which increases the risk of postoperative delirium (POD). Assessing frailty in patients undergoing lower extremity surgery is challenging owing to limited mobility. We investigated whether GS, a simple screening tool, can independently predict POD and aimed to determine the most appropriate criteria for low GS in the Korean population.Methods: This prospective study included patients age
