A Novel Case Report of Iatrogenic Tracheal Rupture Caused by a Laser-Resistant Endotracheal Tube Under Transoral Laser Laryngeal and Nasopharyngeal Surgery.

BACKGROUND Intraoperative tracheal rupture due to endotracheal intubation is a rare but serious complication that requires prompt responses. Transoral laser microsurgery is effective for dissection of laryngeal and nasopharyngeal lesions, and a laser-resistant endotracheal tube is therefore commonly used under general anesthesia. CASE REPORT We present the case of a 69-year-old man in whom a rare complication involving endotracheal tube tip dislodgement during transoral laser surgery led to iatrogenic tracheal rupture.

Two-handed facemask technique effectively causes hyperventilation in electroconvulsive therapy: an observational study.

Background: Electroconvulsive therapy (ECT) remains the mainstay treatment option for patients with psychiatric diseases, such as severe depression. Although various anesthetic techniques provide adequate therapeutic seizures, hyperventilation is a useful adjunct to augment seizure duration and improve seizure quality. We investigated how to efficiently use a facemask to accomplish protocolized hyperventilation and evaluate its effect on ECT seizure.

Factors affecting prolonged time to extubation in patients given remimazolam.

Purpose: To analyze the cause of prolonged recovery from general anesthesia with remimazolam.

Methods: We studied 65 patients under general anesthesia with remimazolam. According to time to extubation, patients were divided into short period (SP) (n = 34, < 15 min) and long period (LP) (n = 31, ≥ 15 min) groups.

[Fibrin-related Markers in Acute Phase of Pulmonary Embolism and Deep Venous Thrombosis].

Background: The fibrin-related markers are considered to be useful in diagnosing pulmonary embolism (PE) and deep vein thrombus (DVT). We measured D-dimer (DD) and soluble fibrin monomer complex (SFMC) in these cases, in order to examine the usefulness of these markers.

Methods: PE patients (P group: 14 cases) and DVT patients (D group : 16 cases) treated in our hospital, were examined.

[The Efficacy of Soluble Fibrin Monomer Complex (SFMC) for Diagnosis of Aortic Dissection (AD)].

Background: Some biomarkers are helpful for AD diagnosis. Although many studies on efficacy of D-dimer have been reported, there are few reports about SFMC. Therefore we conducted a retrospective comparative study of efficacy of SFMC and D-dimer for diagnosis of AD.

[Use of i-gel supraglottic airway for emergency airway management by novice personnel in comparison with laryngeal mask airway and tracheal intubation in manikin models].

Background: Tracheal intubation (TI) is a difficult skill to acquire and its proficiency deteriorates over time if not regularly practiced. However, inexperienced personnel may be required to perform airway management in emergency situations. We compared a novel supraglottic device, i-gel, with laryngeal mask airway classic (cLMA) and TI devices in regard to total success count, time required for placement, and difficulties encountered by novice personnel using a manikin model.

[Adverse events during transcranial muscle evoked potential monitoring].

Background: Transcranial muscle evoked potential (TC-MsEP) monitoring is available to assess spinal cord motor tract function for preventing paralysis in spine surgery. Recently, the quality of monitoring has improved. However, adverse events such as torn tracheal tube, bitten tongue, and mandibular fracture are reported.

[Anesthetic management of a patient with erythropoietic protoporphyria for laparoscopic appendectomy].

Porphyria is a hereditary disorder due to reduction in enzyme activity of heme synthesis system, resulting in accumulation of heme precursors. Erythropoietic protoporphyria (EPP) is a type of porphyria. There are varieties of clinical expressions of EPP such as hepatic damage and photosensitivity, caused by the accumulation of protoporphyrin in the liver and the skin.
