A 23-year-old woman with MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) underwent a laparoscopy-assisted appendectomy. MELAS syndrome is a multisystemic disease caused by mitochondrial dysfunction. General anesthesia has several potential hazards to patients with MELAS syndrome, such as malignant hyperthermia,(More)
BACKGROUND We studied the differences in airway assessment factors among old, middle, and young age groups, and evaluated the frequency and causes of difficult intubation among these groups. METHODS Patients were divided into young (< 40 yr, n = 75 ), middle (40-59 yr, n = 83), and old (≥ 60 yr, n = 89) group. Airway assessment factors such as head and(More)
Despite its effectiveness in other surgeries, studies on continuous epidural block in upper-extremity surgery are rare because of technical difficulties and potential complications. This study compared postoperative analgesic efficacy and safety of ultrasound-guided continuous interscalene brachial plexus block (UCISB) and fluoroscopy-guided targeted(More)
BACKGROUND Appropriate pain management affects outcome after hip fracture surgery. Although multimodal pain management is commonly used for pain control for patients undergoing elective surgery, few studies have evaluated its use in those undergoing hip fracture surgery. This prospective randomized study was designed to determine the clinical value of(More)
It is not known whether changing from isoflurane to desflurane during the latter part of anesthesia shows early emergence and recovery in long surgery. We therefore evaluated the effects of changing isoflurane to desflurane on emergence and recovery. Eighty-two patients were randomly assigned to receive isoflurane (Group I) or desflurane (Group D) or to(More)
BACKGROUND Optiscope™ is a newly developed video stylet device. This study evaluated and compared the hemodynamic changes observed after endotracheal intubation with video stylet and after conventional laryngoscopic endotracheal intubation. METHODS Fifty-eight adult patients with American Society of Anesthesiologists (ASA) physical status class 1 or 2,(More)
R enal artery aneurysms (RAAs) are rare, and even large, single-institution, surgical series only amount to 10 to 35 patients treated over 12 to 20 years.1-3 The most common etiologies are atherosclerosis, fibromuscular dysplasia or other forms of medial degeneration, and Ehlers-Danlos syndrome. True aneurysms of the renal artery occur as often in men as in(More)

provided the original work is properly cited. CC In this issue of the Korean journal of anesthesiology, Bae and colleagues [1] studied the induction and maintenance dose of propofol for anesthesia in major burn patients. They reported that an induction dose of 1.5 mg/kg is appropriate and a slow infusion rate of 20 mg/kg/hr is safe for maintaining the(More)
Seizure associated with antiemetics is rare. We report seizure associated with a 5-HT(3) receptor antagonist in a 38 years old female. The patient underwent ureterorenoscopic lithotripsy due to left upper ureter stone. After operation, the patient complained of nausea in the postanesthetic recovery unit. In order to subside symptom, the patient was(More)
