Purpose: This study was conducted to update the existing nursing practice guideline for intravenous infusion guidelines according to the evidence-based practice guideline in South Korea. Methods: Guideline update process was performed using 22 steps according to the manuals developed by NICE and SIGN. Results: Updated nursing practice guidelines for the intravenous infusion were consisted of 23 domains and 322 recommendations. The number of recommendations in each domain were 4 for general instruction, 12 for vascular access device selection, 20 for site selection, 9 for insertion, 54 for stabilization, 21 for maintaining patency, 4 for blood sampling, 33 for exchange and removal, 28 for add-on device selection, 28, 72 for infusion related complications, 56 for infusion therapies, 7 for education, and 2 for documentation and report. There were 15.9% of A, 30.2% of B, 53.9% of C in terms of grade recommendations. A total of 178 (51.6%) recommendations were newly developed and 24 previous recommendations have been deleted. Conclusion: Updated nursing practice guideline for intravenous infusion was expected to be an evidence-based practice guideline for intravenous infusion in South Korea. This guideline is suggested to be disseminated to clinical nursing settings nationwide to improve the efficiency of intravenous infusion practice.

Afferent loop obstruction following gastrectomy is a rare but fatal complication. Clinical features of afferent loop obstruction are mainly gastrointestinal symptoms. A 56-year-old female underwent radical total gastrectomy with Roux-en-Y esophagojejunostomy for treatment of advanced gastric cancer. After fourteen months postoperatively, she showed gradual development of edema of both legs. Computed tomography (CT) scan showed disease progression at the jejunojejunostomy site and consequent dilated afferent loop, which resulted in inferior vena cava (IVC) compression. A drainage catheter was placed percutaneously into the afferent loop through the intrahepatic duct and an IVC filter was placed at the suprarenal IVC, and self-expanding metal stents were inserted into bilateral common iliac veins. With these procedures, sympotms related with afferent loop obstruction and deep vein thrombosis were improved dramatically. The follow-up abdominal CT scan was taken 3 weeks later and revealed the completely decompressed afferent loop and improved IVC patency. Surgical treatment should be considered as the first choice for afferent loop obstruction; however, because it is more immediate and less invasive, non-surgical modalities, such as percutaneous catheter drainage or stent placement, can be effective alternatives for inoperable cases or risky patients who have severe medical comorbidities.

High-pressure (HP) injection injury to the upper extremity often causes a very serious clinical problem, leading to poor outcomes, including amputation, so that a true surgical emergency is required. The outcomes can be improved with emergent wide surgical debridement. However the diagnosis of these injuries is often delayed due to underestimated evaluation at first appearance and lack of common knowledge of the seriousness of this injury. The type and pressure of the infecting material is an important factor in prognosis and organic solvents infected pressure injury can cause poor outcome and increased amputation rate. In this case, we report on reconstruction of HP oil-based paint injection injuries of the finger using T-shaped pedicles and multiple venous anastomoses. In this concept, arterial flow can be maintained by the reverse flow of distal anastomosis when there is difficulty with the proximal anastomosis. And venous flow can be preserved by deep and superficial vein anastomosis. This concept has various advantages including preserving patency of the pedicle in chronic vasculopathy or trauma cases and maintaining the arterial flow by the reverse flow of distal anastomosis and can improve the free flap survival by a two vascular anastomosis system.

Background: This report describes the authors' experience of "melting" septal cartilage after placement of a septal extension graft in a nasopharyngeal cancer patient that had been previously undergone radiation therapy, and provides a review of the literature. Methods: Electronic medical records were used to obtain details of the patient's clinical history. Results: A 32-year-old woman, who had previously undergone radiotherapy for nasopharyngeal cancer, visited our department to for rhinoplasty. Rhinoplasty was performed using a septal extension graft to raise the nasal tip (first operation). Five days after surgery, it was found that the septal extension graft was melting without any signs of infection, that is, the graft had softened, lost elasticity, thinned, and partially disappeared without any sign of infection at 5 days, and thus, the nasal tip was reconstructed with conchal cartilage (second operation). Five months after surgery, it was found that almost all septal cartilage had disappeared without any sign of infection, and thus, the entire nasal septum was reconstructed using 2-mm costal cartilage and an onlay graft was used for tip augmentation (third operation). Conclusions: After cartilage has been exposed to radiotherapy, its patency should be viewed with suspicion. Further studies are needed for determine the mechanism responsible for cartilage damage after radiotherapy.

While the conventional end-to-end anastomotic technique is accepted as 'the golden standard' for microvascular anastomosis, it is time-consuming and tedious. In an effort to offer faster and safer ways of performing microvascular anastomoses, numerous anastomotic techniques have been proposed, but further refinements in microvascular techniques are still necessary. A 'continuous suture with interrupted knot' technique was devised for faster and safer anastomosis. It has been successfully used in microanastomoses of both artery and vein for free tissue transfer. It is a combination of the interrupted suturing technique and the continuous suturing technique. First, a continuous suture is made with the size of loop decreasing in order, and then the sutures are tied individually from the first loop to the last one as in the conventional interrupted suturing technique. It was applied clinically to fourteen patients over the past ten months and found to be a highly efficient technique that satisfied our needs. This 'continuous suture with interrupted knot' technique has several advantages over other techniques : The operative time is reduced comparing conventional interrupted suture technique. By delaying the tie and with the vessel walls kept separated, the risk of through-stitch can be reduced. Tying all the sutures at one time not only speed up the procedures, but also reduced the surgeon's fatigue. In addition, it has no problem of anastomotic stenosis which is a disadvantage of continuous suture technique. This technique proved to be faster and safer, and has patency equal to that of the conventional end-to-end anastomosis. It is of great help to the surgeon in reducing operative time, especially in clinical situations when many anastomoses are required, or lengthy grafting procedures are undertaken.

Purpose: Nostril stenosis is an uncommon deformity that develops as a consequence of smallpox, chickenpox, tuberculosis, syphilis, congenital malformations etc. There have been several studies on the surgical techniques to treat it. However, it is difficult to maintain the result for a long time. The goal of this study is to evaluate the use of Wplasty, perialar flap as an operative techniques and expansion exercise using Foley catheter as a method to keep the patency of nostril. Methods: This is a retrospective review of the senior surgeon's (Y.L.) patients who underwent W-plasty and a perialar flap. Patients treated from 2005 to 2009 were reviewed and the postoperative results were evaluated. Average patient age was 24 years, ranged from 1 to 61 years, average follow-up period was 27.5 months, ranged from 3 to 77 months. The mild deformity was released with an incision and expansion by the ballooning of a Foley catheter and corrected by W-plasty only. However, a severe deformity required an additional procedure including perialar flap transposition. During the postoperative period, the patients maintained a nasal stent and exercise using a Foley catheter to prevent recurrence. Results: Five cases of nostril stenosis in four patients were treated using this technique. One case was corrected with W-plasty only, but four cases were more severe and were corrected with W-plasty and a perialar flap. There were no perioperative complications. The patients were satisfied with the results and retained a good shape during the follow-up periods. Conclusion: Nostril stenosis can be corrected with W-plasty and a perialar flap. A perialar flap is added if W-plasty is unable to correct the deformity. A postoperative nasal stent and expansion with a Foley catheter can help in preventing recurrences.

Expanded polytertrafluoroethylene (expanded PTFE) graft fistulas are widely used as secondary vascu- lar access for patients receiving long-term hemodialysis treatment. We implanted 48 grafts in )5 patients during the period from August 1990 to August 1995. Forty-three grafts in 32 patients were followed for 1 to 46 months. We performed forearm straight grafts in 36 grafts and upperarm straight grafts in 7 grafts. We experienced 3 operative failures, 22 early and late complications(15 graft thrombosis). Cumulative patency for all grafts at 12 months was 63%, at 24 months 32%, at 36 months 32% Forearm graft survival at 12 months was 55%, at 24 months 30%, at )6 months 30%. Upperarm graft survival at 12 months was 8)oyo and 24 months 41%. After reviewing our experience, we think that expanded-PTFE grart as secondary vascular access still have many complications and low survival than autogenous a teriovenous fistula. And so utilization of the expanded PTFE fistula requires better techniques, close observation and maintenance to keep it functional.

Although most of the patients with endobronchial tuberculosis have some degree of bronchial stenosis, more aggressive treatment is needed to restore the patency of the involved tracheobronchial tree for some patients not responding well to antituberculous chemotherapy combined with steroids. In our first case, we reseated stenotic trachea in a 42 years old women who showe overgrowing granulation tissue through the modified Gianturco steno wire which was previously inserted and anastomosed end to end. Another case was a 37 years old male with left main bronchial rcstenosis complicate, $\boxUl$ after inserting a Strecker stent and sleeve left upper lobectomy was performed.

Background: Minimally invasive direct coronary artery bypass surgery(MIDCAB) has been increasing in interest along with the new techniques in myocardial immobilization for easier and safer procedures. Until the opening of the era of new techniques, adequate accuracy and good patency of grafts were debatable. Our experiences of MIDCAB were studied according to the stages of technical developments. Material and Methods: Since March 1996, 55 patients have undergone MIDCAB procedures. The patients of off-pump CABG(no cardiopulmonary bypass under full sternotomy) were excluded from the study. In the early experience(Stage I), a left anterior small thoracotomy through the left parasternal incision was performed(n=6); then an approach through the lower partial sternotomy was used(Stage II, n=33); and recently, a chest wall elevator for harvesting the internal thoracic artery and the foot plate for myocardial immobilization have been used(USSC, Norwalk, CT)(Stage III, n=16). Result: The surgical procedures of four patients in the Stage II group have been converted to conventional bypass because of the deeply seated left anterior descending coronary artery in two patients, fracture of the calcific lesion in the right coronary artery in one patient, and a cardiogenic shock during hypothermia in the other patient with ventricular dysfunction. Two patients in stage II experienced symptomatic recurrences after surgery and restenosis was verified on angiocardiography. They were managed by interventional procedures. All the other patients were doing well without symptoms, except one patients in Stage II who underwent PTCA procedure for a lesion in the circumflex artery during the follow up period. Conclusion: The new and specialized devices are essential to the development of MIDCAB surgery. MIDCAB and the hybrid procedures in multi-vessel disease are on the way to further development. So far, our experience is limited only to a single device among the many new devices for the purpose.
