고관절 전치환술 동안 발생한 치명적인 외부 장골정맥 손상
이강우 ( Kang Woo Lee ),조영현 ( Jo Young Hyun ),이재우 ( Jae Woo Yi ) 경희대학교 경희의료원 2011 慶熙醫學 Vol.27 No.1
63세의 여자 환자가 고관절의 이차성 골관절염으로 인하여 고관절 전치환술을 받기로 하였다. 수술이 끝나갈 무렵 절개부위를 봉합하던 중 환자의 혈압과 혈색소치가 급격히 하락하기 시작하였으며 빈맥과 호기 말 이산화탄수 수치의 하강이 나타났다. 수술이 끝난 후 환자의 피부가 창백한 것을 제외하고는 별다른 이상을 발견할 수 없었으며 보다 자세한 검사를 위하여 전산화 단층촬영, 복부 초음파, 경식도 심장 초음파, 혈관 조영촬영을 시행하였다. 그 결과 좌측 외부 장골정맥과 좌측 총 장골정맥 사이에서 현성 출혈이 관찰되었다. 환자는 즉시 응급 수술을 받았으며 수술 도중 대량 수혈이 시행되었다. 이에 본 저자는 수술 도중 출혈을 거의 동반하지 않은 고관절 전치환술 동안 발생한 외부 장골정맥의 손상에 의한 대량의 복막 뒤 출혈과 출혈성 쇼크를 경험하였기에 보고하는 바이다.
MEDICOS : An MDO-Enabling DIstributed COmputing System

This paper presents a computing system, called MEDICOS, that enables Multidisciplinary Design Optimization (MDO) technology for engineering design on distributed environments. In MDO, various legacy softwares have to be integrated, so dynamic configuration and seamless coordination between these legacy softwares must be supported. MEDICOS is designed to address these issues by the Linda shared memory model-based design and the agent-based wrapper technology. A prototype system for engineering designs is developed and tested with designing a super high temperature vacuum furnace.

Purpose: Yawning is a common phenomenon. In daily life and during induction of general anesthesia yawning is easily observed. Its physiology is unknown. But to keep alert during our daily life is widely accepted as the purpose of yawning. Oxygen deficit as a trigger factor of yawning is questioned. The purpose of this study is to know the different oxygen concentration could occur the yawning during induction of general anesthesia. Methods: 22 patients (age 20 to 65 years old), each of ASA physical status Ⅰ-Ⅱ, were randomly assigned into two group. Each group were given preoxygenation with 100% oxygen 6 liter or with 100% oxygen 2 liter (FiO2 1.0) and 4 liter of air (FiO2 0.473) for 3 minutes. After injection of propofol (2 mg/kg), occurrence of yawning was closed observed. Results: After administration of propofol, 8 patients yawned in FiO2 1.0 preoxygenation group. And 5 patient yawned in FiO2 0.473 group. Incidence rate is 72.7% and 45.5% respectively. P-value is 0.387. Conclusion: Different oxygen concentration in preoxygenation during induction of general anesthesia does not trigger yawning.

Gitelman syndrome is a rare autosomal recessive salt-losing renal tubulopathy characterised by hypomagnesemia, hypocalciuria and secondary aldosteronism, which results in hypokalemia and metabolic alkalosis. Acute exacerbation of the hypokalemia and the metabolic alkalosis may interfere with surgery and general anesthesia. Anesthesiologists should be aware of pathogenesis and clinical sypmtoms of Gitelman syndrome to prevent possible complications during perioperative period. It is important to keep an eye on the electrolytes and pH during and after surgery.

Schwannoma is one of the most common benign tumors of the nerve sheath. Most common locations are flexor surfaces of the extremities, neck, mediastinum, retroperitoneum, posterior spinal roots, and cerebellopontine angle. Schwannoma occurs very rarely on the chest wall. Here, we have a case of chest wall schwannoma, which presented as incidentally detected chest wall tumors. Schwannoma, being a slow growing benign tumor, is incidentally detected on chest imaging done for vague complaints. Computerized tomography (CT) scan supports the diagnosis of schwannoma and is essential to assess the extent of the tumor. Treatment of choice is surgery, thoracoscopic approach is preferred.

Hypersensitivity reactions remain a major problem in the perioperative period. These reactions are rapid onset and start within seconds to minutes of exposure to the allergen. Symptoms progress rapidly and can affect most organ systems. Anesthesiologists use a variety of drugs during provision of an anesthetic and may be involved in risk of hyperseneitivity reactions. We report a case of anaphylaxis which is developed in discectomy during general anesthesia. Anaphylaxis is a potentially life-threating reaction the requires immediate treatment including epinephrine as a first choice vasopressor.

Pseudomeningocele is rare complication after lumbar discectomy. Most pseudomeningoceles are asymptomatic, but sometimes can cause headaches, infection, back pain, and radicular pain. Treatment modalities include conservative management, epidural blood patch, lumbar subarachnoid drainage, and surgery. We report a successful treatment of pseudomeningocele with epidural blood and fibrin glue patch, which did not treated with conservative management and epidural blood patch alone.
