Background: Goal of the initial treatment of primary spontaneous pneumothorax is re-expansion of the lung by evacuation of air from pleural space. Authors thought small caliber catheter could reach to this goal instead of conventional large bore chest tube. This retrospective study was undertaken to assess the effectiveness of 7-French (Fr) catheter for the initial treatment of primary spontaneous pneumothorax. Material and Method: Between May 2003 and April 2005, 111 patients with primary spontaneous pneumothorax were managed with tube drainage; 7 Fr catheter for 86 patients and 24-French chest tube for 25 patients. We analyzed catheter indwelling time, use of analgesics, re-expansion of the lung, and catheter related problems by medical records. Result: Mean catheter indwelling time was $2.4{\pm}1.1$ days in 7 Fr group and $2.3{\pm}1.3$ days in chest tube group (p>0.05). All patients with 24 Fr catheter needed analgesics injection but never in 7Fr group. Complete re-expansion of the lung based on plane chest radiograph was obtained in 77% of 7 Fr group. The problem related with 7 Fr catheter was kinking, which showed in 5.6%. Conclusion: Application of the 7 Fr catheter for initial management of primary spontaneous pneumothorax was as effective as 24 Fr catheter.

Central venous catheterization is one of the most important procedures for initial resuscitation of hemodynamically unstable patients including multiple trauma patients. Inadvertent arterial placement of the large caliber central venous catheter can results in resuscitation failure as well as unnecessary invasive treatment. Here, we report an arterial puncture during central venous catheterization which may lead to inadvertent arterial catheterization. We recommend that arterial catheterization should be evaluated before dilator insertion during Seldinger's method. Ultrasound can help in preventing the inadvertent arterial catheterization of central venous catheter.

Purpose: This study was a predicative survey to provide home care clients with indwelling urinary catheters for furnishing basic educational material to their families by analyzing the family members' knowledge, educational needs and educational experience about indwelling catheter management. Method : The subjects consisted of 108 family members who cared for home care clients with indwelling catheters. Data were collected by home care nurses in nine hospitals in Pusan, who directly interviewed with them through questionnaires from Sep. 6th to 30th in 2004. The questionnaires for data collection were developed through pre-survey and reference review. The collected data was analyzed by using frequency, percentile, mean, variation, t-test, ANOVA on SPSS 10.1 package. Results : There were characters of home care clients with indwelling catheters: women(67.6%) were more than men; the average age of them was $69.60{\pm}14.99$ years old; neurogenic and cerebrovascular diseases(80.0%) were the most common disease group; 81.5% of them were totally dependent on others in terms of level of activity. Home care clients' families had these characters: women(76.9%) were more than men; the average age was $54.5{\pm}13.70$ years old; 46.3% of them were parents or sons or daughters in terms of relation with patient; tl1e average care period was $39.8{pm}34.20$ months. Level of knowledge about indwelling catheter management of the family members were 69.8% and its mean were $20.24{\pm}4.53$. Educational needs were 90.9% and its mean were $14.55{\pm}3.56$. Educational experience were 53.3% and its mean were $8.53{\pm}4.30$. 'Complications in using an indwelling catheter', 'Symptoms to call for a home care nurse' and 'Method to attach an indwelling catheter' were high ranked in both educational needs and educational experience. 'Anatomy of urinary tract', 'Functions of urinary tract' and 'Catheter placement' were low ranked in both educational needs and educational experience Level of knowledge about indwelling catheter management of the families showed a significant difference according to their age(F=5.35, p=0.01). Educational needs showed a significant difference according to care period(F=3.06, p=0.04). Conclusion: the family members' level of knowledge and educational experience about indwelling catheter management and their educational were not sufficient while their educational needs were high. In other words although the family members were acknowledged education needs, but the care for the patients with indwelling catheter weren't performed well because of their lack of related knowledge. Therefore systematic educational programs about indwelling catheter management for home care clients and their families should be made on the base of this study.

A guideline for determining the optimal catheter length according to the patient's physique during tunnel-type dialysis catheter insertion used in renal failure patients is presented, and the maintenance of the function of the dialysis catheter is evaluated. From October 1, 2015 to February 31, 2016, a total of 110 (male : female = 73 : 37) patients who underwent tunnel-type dialysis catheterization performed at our hospital were treated without using guidelines. The group was divided into A group, and the group treated using the guideline into B group. Results were analyzed statistically using SPSS 20.0. As a result of the dialysis catheter insertion procedure according to the use of guidelines, the function maintenance rate of group A was 81.8%, and the function maintenance rate of group B was 96.3%. In the case of tunnel dialysis catheter procedure, the function maintenance effect was statistically significant in the group treated using the guideline compared to the group not using it (p<0.05). It can be said that it is more effective when information on the patient's underlying disease is reflected in addition to the use of guidelines.

Catheter fragment and embolism are both potentially serious complications associated with the use of an intravenous (IV) catheter for contrast media bolus injection, and may be followed by serious or lethal sequelae. Though catheter fragment is a rare complication of IV catheter insertion, especially in peripheral veins, CT can be used to detect residual fragment. This study demonstrates the utility of MDCT to localize a small, subtle peripheral venous catheter, which can be easily reformatted of MDCT reformations. Various 3D techniques such as MPR and MIP, volume rendering, and shaded-surface displays are currently available for reconstructing MDCT data. Advances in MDCT technology contribute substantially to the detection and accurate localization of smaller IV catheter fragment.

Background: Epidural anesthesia is widely used to provide pain relief, whether for surgical anesthesia, postoperative analgesia, treatment of chronic pain, or to facilitate painless childbirth. In many cases, however, the epidural catheter is inserted blindly and the indwelling catheter position is almost always uncertain. Methods: In this study, the loss-of-resistance technique was used and an imaging agent was injected through the indwelling epidural anesthesia catheter to confirm the position of its tip and examine the migration rate. Study subjects were patients scheduled to undergo surgery using general anesthesia combined with epidural anesthesia. Placement of the epidural catheter was confirmed postoperatively by injection of an imaging agent and X-ray imaging. Results: The indwelling epidural catheter was placed between upper thoracic vertebrae (n = 83; incorrect placement, n = 5), lower thoracic vertebrae (n = 123; incorrect placement, n = 5), and lower thoracic vertebra-lumbar vertebra (n = 46; incorrect placement, n = 7). In this study, a relatively high frequency of incorrectly placed epidural catheters using the loss-of-resistance technique was observed, and it was found that incorrect catheter placement resulted in inadequate analgesia during surgery. Conclusions: Although the loss-of-resistance technique is easy and convenient as a method for epidural catheter placement, it frequently results in inadequate placement of epidural catheters. Care should be taken when performing this procedure.

Background: Conventional ascending aortic cross clamping is often limited. This study was carried out to evaluate the safety and efficacy of an endovascular aortic clamping technique with an intraaortic balloon catheter. Material and Method: From April 2004 to January 2007, surgery with endoaortic clamping was performed in seven patients. A retrograde access perfusion (RAP) catheter was used in six patients and a Pruitt's balloon catheter in two patients. The indication for the operation was a retrosternal pseudoaneurysm of the aortic root in six patients, diffuse calcification of the ascending aorta with aortic regurgitation in 2 patients and an atrial septal defect in one patient. Five patients had at least two prior cardiac surgeries. Result: Successful insertion of the catheter and endoaortic clamping was achieved in all patients. Conclusion: The endovascular aortic clamping technique with a balloon catheter was a useful alternative method for patients in whom conventional cardiac surgery was limited.
