연구배경: 폐쇄관을 이용한 기관내 흡인은 임상적으로 중한 환자에게 생리적인 이점이 있지만, 병원성 균주에 의한 기관지 내의 집락화가 증가될 수 있다는 보고가 있다. 비용증가는 폐쇄흡인의 또 다른 제한점이다. 본 연구는 폐쇄흡 인 및 개방흡인에 따른 병원균주의 집락화와 인공환기관련폐렴의 빈도와 가격효율성을 비교해보고자 시행되었다. 방 법: 각각 한 달의 간격을 사이에 두고 내과계 중환자실에 입원한 환자들을 대상으로 다중사용 개방흡인, 단일사용 개방흡인, 다중사용 폐쇄흡인을 순차적으로 시행하였다. 비용, MRSA의 기관지내 집락화, 인공환기폐렴의 발생 률을 분석하였다. 결 과: 106명의 환자가 연구 대상으로 포함이 되었고, 이 중 20명의 환자가 다중사용 개방흡인을, 42명이 단일사용 개방흡인을, 44명이 다중사용 폐쇄흡인술을 시행받았다. MRSA의 집락화와 인공환기관련폐렴의 빈도는 세 군간에 의미있는 차이를 보이지 않았다. 입원 일당 소모되는 비용은 다중사용 개방흡인이 $10.58, 단일사용 개방흡인이 $28.27, 다중사용 폐쇄흡인의 경우 $23.76인 것으로 나타났다. 결 론: 다중사용 폐쇄흡인을 매 48시간마다 교환하는 경우 MRSA 집락화와 인공환기폐렴 발생 빈도는 비슷하였고, 기관내 흡인술에 있어서 비용면에서도 효율적인 방법임을 알 수 있었다.

Purpose: Many surgical methods for reconstruction of orbital floor fracture have been reported, which include subciliary approach, transconjunctival approach, transantral and transnasal endoscopic approach, etc. The purpose of this study is to demonstrate a surgical technique and analyze the results of transnasal endoscopic approach with Foley catheter ballooning without implantation of artificial surgical material through subciliary approach. Methods: Between February 2007 and November 2010, 29 orbital floor fracture patients, who had no herniated muscles through bone fragments, were treated through transnasal endoscopic approach with Foley catheter ballooning. Under the endoscopic view, the operator identified the opening of maxillary sinus. After widening of the opening using forceps, the operator reduced the fragmented bone with curved suction tip. Thereafter, 18-Fr Foley catheter was inserted. Four weeks after the operation, the catheter was removed. Results: Preoperatively, 6 patients had diplopias, 4 patients had limitations of extraocular motions and 3 patients had enophthalmos. After removal of the Foley catheter 4 weeks after the operation, 2 patients had diplopias, 1 patient had a limitation of extraocular motion, 1 patient has an enophthalmos and 1 patient had numbness on the cheek. These symptoms were resolved about 6 months after the surgery. Conclusion: The operative technique of Foley catheter ballooning through transnasal endoscopic approach without implantation of the artificial surgical material through subciliary approach can be considered one of the appropriate techniques for orbital floor fracture.

Objective: This study examined the incidence and amount of air inflow during central venous catheter (CVC) insertion. Methods: This study was an experimental study aimed at designing an apparatus to implement blood vessel and blood flow in the human body. A 1.5-m long core tube with a Teflon tube, suction rubber tube, and polyvinyl chloride tube were made. This core tube was assumed to be the blood vessel of the human body. Blood was replaced with a saline solution. The saline solution was placed higher than the core tube and flowed into the inside of the tube by gravity. The CVC was injected 15-cm deep into the core tube. The air was collected through a 3-way valve into the upper tube. The experiments were carried out by differentiating the pressure in the tube, CVC insertion step, and diameter of the end of the catheter. The experiment was repeated 10 times under the same conditions. Results: The amount of air decreased with increasing pressure applied to the tube. Air was not generated when the syringe needle was injected, and the amount of air increased with increasing size of the distal end catheter. Conclusion: To minimize the possibility of air embolism, it is necessary to close the distal end catheter at the earliest point as soon as possible.

Apatient, 51 years old woman, had suffered form headache and decrease of visual acuity. She had $3{\times}3cm$ sized giant aneurysm originated in cavernous and clinoid portion of left ICA(C4,C5) in the cerebral angiography. Before craniotomy, left CCA was exposed and 6F double lumen catheter was inserted in left ICA through the sheath. Pre-operative angiography was done. balloon catheter was positioned at the petrous portion of ICA. Eyebrow approach was done and giant aneurysm was exposed. The proximal blood flow was controlled with balloon dilatation and suction and decompression was tried, then multiple clips were applied. The loss of distal blood flow under intra-operative angiography was notified after clipping. The position of clips were repositioned to preserve blood flow & the rich flow was confirmed at distal part of clipping. In the post-operative cerebral angiography, the same finding was shown.

Purpose: Concept analysis was performed on the behavioral concept of endotracheal suctioning (ETS), to identify the goal, to develop astandardized clinical protocol, to identify the antecedents and consequences, and to differentiate the improper use of ETS. Method: Walker & Avant's concept analysis was employed using clinical guidelines, books and review articles in which the procedures of ETS were written in detail and published in Pubmed within the last 20 years. Result: The macro-goal of ETS was to remove accumulated respiratory secretions. Three defining attributes of ETS were identified; catheter, suctioning and asepsis. Each attribute involved empirical referents, such as the size and depth of the catheter, the suction pressure, duration and method for suctioning. The antecedents of ETS were identical to the clinical evidences for the need of ETS such as the nursing assessment data. The consequences of ETS serve as an evaluation criteria on the effectsof ETS based on the goal of ETS. Conclusion: The concept analysis of ETS demonstrates an example of considering a specific nursing protocol of ETS as a behavioral concept, applying concept analysis to it to identify it's key behavioral components as defining attributes and empirical referents and then developing and applying the standard ETS protocol.

This report details a case of unexpected, severe post-operative cerebral edema following cranioplasty. We discuss the possible pathological mechanisms of this complication. A 50-year-old female was admitted to our department with sudden onset of stuporous consciousness. A brain computed tomography (CT) revealed a subarachnoid hemorrhage with intracranial hemorrhage and subdural hematoma. Emergency decompressive craniectomy and aneurysmal neck clipping were performed. Following recovery, the decision was made to proceed with an autologous cranioplasty. The cranioplasty procedure was free of complications. An epidural drain was placed and connected to a suction system during skin closure to avoid epidural blood accumulation. However, following the procedure, the patient had a seizure in the recovery room. An emergency brain CT scan revealed widespread cerebral edema, and the catheter drain was clamped. The increased intracranial pressure and cerebral edema were controlled with osmotic diuretics, corticosteroids, and antiepileptic drugs. The edema slowly subsided, but new low-density areas were noted in the brain on follow-up CT 1 week later. We speculated that placing the epidural drain on active suction may have caused an acute decrease in intracranial pressure and subsequent rapid expansion of the brain, which impaired autoregulation and led to reperfusion injury.

To maintain an adequate airway in a patient with tracheobronchial narrowing coming from various causes, prosthetic tracheobronchial stents provide palliative treatment for narrowed airways where surgical resection is inadvisable. After insertion, previous reported complications were granuloma formation, dysphagia, suction catheter entrapment and fatal massive hemoptysis. We report, a case of complication associated with expandible metallic stent with endobronchial stenosis due to tuberculosis.

배 경 : 폐 농양은 괴사된 폐실질에 농이 고이는 질환으로 1940년대 이전까지는 폐 농양은 체외 배액술에 의한 방법이 치료 원칙이었으나 피 이후 파양한 항생제의 발달로 대부분의 폐 농양에서는 항생제와 체위적 배농술을 포함한 내과적 치료법이 매우 효과적으로 이용되어 왔고 내과적 치료에 실패한 경우에 한해서 폐엽 절제를 포함한 외과적 치료 방법이 적용되어 왔다. 농흉은 흉막강내에 농이 고이는 질환으로 흉수 그람 염색상 양성이어야 하고 약제의 효과적인 침투가 어려우므로 내과적인 치료만으로 치유를 기대할 수 없고 흉관삽관 등 수술적인 조작이 필요하다. 하지만 최근 환자의 전신상태가 불량하거나 외과적 폐절제술이 용이하지 않는 경우에 국소 마취로 직경이 작은 카테타를 사용하여 경피적으로 배농시켜 치료하는 방법을 시행하고 있다. 이에 본 연구에서는 한양대학병원에 내원한 폐 농양 10례와 농흉 23례의 환자를 대상으로 pig-tail 도관 배액술을 시행하였기에 이에 대한 치료 효과를 보고하는 바이다. 대상 및 방법 : 1990년 1월 1일부터 1996년 5월 20일까지 한양대학병원에서 입원 치료한 환자중에서 pig-tail 도관을 이용하여 치료한 폐 농양 환자 10례와 농흉 환자 23례를 대상으로 하였고 각 환자들은 도관 배액술 전에 단순 흉부 X-선사진과 흉부 전산화 단층촬영을 하였고 형광 투시 또는 초음파 유도하에서 천자를 시행하였다. 천자후 카테타는 배액이 잘 되는 위치에서 피부에 고정되어었고 매일 배액량을 관찰한 후 3-4일 간격으로 단순 흉부 X-선사진을 검사하여 폐 농양의 크기나 농흉의 크기가 줄고 임상적 호전이 있으면서 배농량이 하루 5ml이하일때 도관을 제거하였다. 결 과 : 원인균은 폐 농양에서는 Staphylococcus aureus aureus 1례, Klebsiella pneumoniae 1례였으며 농흉에서는 결핵균이 14례로 가장 많았고 2례에서는 Streptococcus pneumoniae 였고 나머지에서는 균의 성장을 관찰할 수 없었다. 카테타의 삽입기간은 폐농양에서는 1-2주 사이가 7례(70%)였으며 농흉에서도 1-2주 사이가 14례(60.8%)로 가장 많았다. 경피적 배농은 29례(87.8%)에서 성공적이었으며 그 중 20례(60.6%)에서는 그 크기가 빠르게 감소되었다. 결 론 : 폐 농양과 농흉에서 pig-tail도관을 통한 배농은 항생제 요법과 보조 요법에 반응하지 않는 경우와 외과적인 수술의 어려움이 있는 환자들에서 비교적 안전하게 선택할 수 있는 효과적인 치료 방법으로 생각된다.

Purpose: The purpose of this study was to investigate differences between a pulmonary aspiration group and a non-pulmonary aspiration group in glucose concentration of tracheal secretions by measuring time and feeding methods. Method: The subjects were 36 ICU patients who were receiving formula via nasogastric tubes and had endotracheal tubes or tracheostomy tubes. Tracheal secretions were collected by connecting suction traps to a suction catheter in three different times(within 1 hour after feeding, between 1 to 2 hours after feeding, and between 2 to 3 hours after feeding) for 2 days, overall six times. Glucose concentration of tracheal secretions was measured with the glucometer(Accucheck II). Results: Glucose concentration of tracheal secretions increased in progression after feeding. The mean of specimens collected last(between two to three hours after feeding) was shown to be the highest value(M=61.61mg/dl) in the pulmonary aspiration group. Significantly(p=.000) more subjects(94.44%) in the pulmonary aspiration group received formula via a 50cc syringe than those in the non-pulmonary aspiration group(22.22%). Conclusion: Critically ill patients may need more time for head-elevation after tube feeding to prevent pulmonary aspiration. In practice, enteral formula should not be given the patients via a $50_cc$ syringe anymore, instead a feeding bag or infusion pump should be used to prevent pulmonary aspiration.
