This study was performed in order to evaluate the risk factors for nosocomial urinary tract infection and the frequencies of organisms isolated, and to provide the epidemiologic and basic data of hospital acquired urinary tract infection in intensive care unit. A prospective analysis was performed with 1,235 urine samples following urinary bladder catheterization in 569 patients, who had no evidence of UTI at the time of catheter insertion, admitted to intensive care unit in Pusan P hospital between June 1997 and May 1998. To identify risk factors for UTI, clinical characteristics of infected patients were analyzed. We analyzed these data by percentage, chi-square and odd ratio. Obtained results were as follows: A total of 569 patients (male 341 and female 228) were an average age of 50.8 years and catheterization of 8.04 days. Incidence of UTI was 16.1% (199/1,235) and The risk factors of UTI were duration of catheterization over 7 days, no use of systemic antibiotics, summer and female, and During the first 7 days these risk factors were no use of systemic antibiotics, summer, place of first catheter insertion (ICU) and type of intensive care unit (NSICU). A total of 220 the isolated strains were Gram negative rod 83 (37.7%), yeast like fungi 74 (33.6%) and Gram positive cocci 63 (28.6%). The common organisms isolated were Enterococcus faecalis 23 (10.5%), Serratia marcescens 19 (8.6%), Pseudomonu spp.17 (7.7%), E. ooh 16 (7.3%), Staphylococcus epidemidis 11 (5.0%) mdklebsiellapneumoniae 8 (3.6%). Therefore, in these results 199 of 569 (35%) patients in ICU with indwelling urinary catheter developed UTI. The risk factors for UTI are prolonged duration of catheterization, no use of systemic antibiotics, summer, and female.
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.

Intrathecal drug administration system (ITDAS) can reduce the side effects while increasing the effectiveness of opioids compared to systemic opioid administration. Therefore, the use of ITDAS has increased in the management of cancer pain and chronic intractable pain. Catheter obstruction is a serious complication of ITDAS. Here, we present a case of catheter obstruction by a mass formed at the side hole and in the lumen. A 37-year-old man suffering from failed back surgery syndrome received an ITDAS implantation, and the ITDAS was refilled with morphine every 3 months. When the patient visited the hospital 18 months after ITDAS implantation for a refill, the amount of delivered morphine sulfate was much less than expected. Movement of the pump rotor was examined with fluoroscopy; however, it was normal. CSF aspiration through the catheter access port was impossible. When the intrathecal catheter was removed, we observed that the side hole and lumen of the catheter was plugged.

Central venous catheter (CVC) for long-term venous access is indispensable for various reasons including hyperalimentation, frequent blood sampling, frequent IV drug use in pediatric patients. We report clinical experience of surgical neonates in whom CVC was inserted primarily via great saphenous vein into suprarenal inferior vena cava. From March 2004 to March 2006, we performed CVC insertion via saphenous vein - contralateral side to main wound - into suprarenal inferior vena cava in surgeries of neonates. 2.7Fr or 4.2Fr, single lumen, tunneled Broviac catheters (Bard Access system, Inc, Salt Lake City, Utah) were used. Skin exit site of tunneled catheter was located in ipsilateral flank area just below edge lower rib. At the end of the procedure, location of the catheter tip was confirmed by plain radiography of abdomen. We retrospectively reviewed the admission records of the patients including nursing staff charts. Nine (50.0 %) patients were male and nine (50.0%) were female. Median gestational age was 38 weeks (range, 29-42 weeks) and median birth weight was 3,105 gm (range, 1,040-3,720 gm). Median age at catheter insertion was 38.5 days (range, 1-236 days). The purpose of CVC insertion was short-and long-term hyperalimentation in nine (50.0 %) patients. CVC insertion was performed in operation room under general anesthesia in sixteen (88.9 %) patients (in these cases, CVC insertion was performed just prior to concurrent operation) and neonatal intensive care unit (NICU) under local anesthesia with adequate sedation in two (11.2%). During the admission period (total catheter-indwelling time: 553 days), CVC functioned well without any significant side effects. Transient swelling of the ipsilateral leg (n=1, 5.6 %) and transient migration of catheter tip (n=1, 5.6 %) were noted, which did not affect function of the indwelled CVC. Mean catheter-indwelling time was 30.7days (range, 3-72 days). All catheters were removed electively except two mortality case. Complications, such as thrombosis, infection, kinking or extravasation of drugs, were not observed in our study period. Tunneled trans-great saphenous vein inferior vena cava catheters are not only comparable to cervical CVCs in terms of function and complication rates, but also very beneficial in selected patients, especially those in whom cervical approach is technically impossible or contraindicated.
Cranial implant removal is recommended if implants become exposed owing to scalp necrosis after cranioplasty. However, it carries the risk of extensive bleeding, and the resultant cranial defects can cause both aesthetic and functional problems. We present a case of a scalp defect exposing a cranial prosthetic implant that was reconstructed with a local flap and salvaged using an indwelling antibiotic irrigation system. A 73-year-old man presented with scalp necrosis after undergoing cranioplasty due to intracranial hemorrhage. The cranial implant was exposed through the scalp defect. Methicillin-resistant Staphylococcus aureus was detected in the culture from the open wound. After debridement of the necrotic tissue and burring of the superficial layer of the implant, a transposition flap was used to cover the defect and an indwelling antibiotic irrigation system was installed. Continuous irrigation with vancomycin was conducted for 5 days, and intravenous vancomycin was continued for 4 weeks. The flap was in good condition at 4 months postoperatively, with no infection. The convex contour of the scalp was well maintained. The patient's neurological status was stable. Exposed cranial implants can be salvaged with continuous antibiotic irrigation as an alternative to implant removal; thus, the risk of bleeding and possible disfigurement may be avoided.

The purpose of this study is to identify the knowledge of and adherence to the infection control guidelines for indwelling urinary catheters, central venous catheters and ventilators among intensive care nurses. The subjects were 175 intensive care nurses working in 2 upper general hospitals and 3 general hospitals. Data were collected from July 1 to July 31, 2013. The collected data were analyzed by descriptive statistics, t-test and ANOVA using SPSS 18.0 for Windows. The mean scores of the knowledge of the infection control guidelines on indwelling urinary catheters, central venous catheters and ventilators were 0.87, 0.82 and 0.82 points, respectively. The average scores for the adherence to the infection control guidelines for indwelling urinary catheters, central venous catheters and ventilators were 4.18, 4.04 and 4.07 points, respectively. Statistically significant correlations were found between the knowledge of and adherence to the infection control guidelines for indwelling urinary catheters (r=.72, p<.00), central venous catheters (r=.54, p<.001) and ventilators (r=.30, p<.001). The knowledge of and adherence to the infection control guidelines for indwelling urinary catheters differed significantly according to gender, educational status, total career, number of patients, type of hospital, and attendance of seminar. The knowledge of and adherence to the infection control guidelines for central venous catheters differed significantly according to educational status, total career, number of patients, type of hospital, and attendance of seminar. The knowledge level of the infection control guidelines for the ventilator differed significantly according to the total career. The results of this study indicate that education and training programs for improving the knowledge of adherence to the infection control guidelines should be developed.
Background: It has recently become most general to use the small bore catheter to perform closed thoracostomy in treating iatrogenic pneumothorax. This study was performed for analysis of the efficacy of treatment methods by using small bore catheter such as 7 F (French) central venous catheter, 10 F trocar catheter, 12 F pigtail catheter and for analysis of the appropriateness of each procedure. Materials and Methods: From March 2007 to February 2010, Retrospective review of 105 patients with iatrogenic pneumothorax, who underwent closed thoracostomy by using small bore catheter, was performed. We analyzed the total success rate for all procedures as well as the individual success rate for each procedure, and analyzed the cause of failure, additional treatment method for failure, influential factors of treatment outcome, and complications. Results: The most common causes of iatrogenic pneumothorax were presented as percutaneous needle aspiration(PCNA) in 48 cases (45.7%), and central venous catheterization in 26 cases (24.8%). The mean interval to thoracostomy after the procedure was measured as 5.2 hours (1~34 hours). Total success rate of thoracostomy was 78.1%. The success rate was not significantly difference by tube type, with 7 F central venous catheter as 80%, 10 F trocar catheter as 81.6%, and 12 F pigtail catheter as 71%. Twenty one out of 23 patients that had failed with small bore catheter treatment added large bore conventional thoracostomy, and another 2 patients received surgery. The causes for treatment failure were presented as continuous air leakage in 12 cases (52.2%) and tube malfunction in 7 cases (30%). The causes for failure did not present significant differences by tube type. Statistically significant factors affecting treatment performance were not discovered. Conclusion: Closed thoracostomy with small bore catheter proved to be effective for iatrogenic pneumothorax. The success rate was not difference for each type. However, it is important to select the appropriate catheter by considering the patient status, pneumothorax aspect, and medical personnel in the cardiothoracic surgery department of the relevant hospital.
Background : Patients mover more as their post operative pain decrease. With the increase in movement there will be a tendency for the epidural catheter to migrate out of its original position. We studied 2 methods of fixation of the epidural catheter and the changes in position as related to patient movement. Methods : Patients were divided into two groups. Patients in Group A had their epidural catheter formed with a circular loop at the (skin) exit site then directed over the right shoulder. Group B had the epidural catheter flxed with Fixomull on the exit site without forming a circular loop. At the end of the operation, 3 mg of epidural morphine was injected via indwelling epidural catheter for postoperative pain control. Epidural catheter depth was measured 24 hours later. Results : The overall rate of migration of epidural catheter was 61.9%. In Group A, number of patients whose catheter migrated over 0.5 cm was 23(69.9%) with 14 inward migration and 9 outward migration. Group B had 16(53%) patients catheters migrate over 0.5 cm, with 2 patients having inward migration and 14 outward migration. Conclusions : Although the rates of migration of epidural catheter were similar for both groups, the number of inner migration of catheter, which could result serious complications, was significantly lower in Group B than Group A. Based on our results we recommend the epidural catheter be fixed without a circular loop.
This Study was conducted at Intensive Care Unit of H & S Hospitals from Jan 4 to April 7, 1981 on 14mail & 26female adult patients. Each patient was screened and found to have nonbacteriuria in clean catch specimen before catheterization. Clean catch apecimen through Foley catheter were obtained after 24hours, 48hours and 72hours from catheterization. The result of this study is reviewed in a statistical analysis of percentage & Chi Square test to obtain the following findings. 1) The occurenc of bacteriuria in patients according to duration of indwelling catheter. a. 9.1% of the patient showed evidence of bacteriuria 24hours post catheterization specimen and 60% showed 48hours post cathetreization, while 68.4% of the patient showed evidence of bacteriuria 72hours post catheterization specimen. The occurence of bacteriuria in patients were significant differences at 1% level between duration of indwelling catheter. b. Mail patients had no infection 24hours post catheterization, 50% displayed bacteriuria 48hours post catheterization & 62.5% displayed bacteriuria 71hours post catheterization. 11.1% of femail patients displayed infection 24hours post catheterization 66.7% displayed infection 48hours post catheterization and 72.7% displayed infection 72hours post catheterization. There were significant differences at 1% level between bacteriuria occurence of mail & femail patients and the duration of insertion. 2) 56% of those patient who have altered mental state developed bacteriuria, while 40% of those patient who have alear mental state developed bacteriuria. But there was without statistically any significant difference between patient's mental status. 3) The occurence of bacteriuria with the administration of antibiotics in 36 patient was in 50%. The occurence of bacteriuria without the administration of antibiotics in 4 patients was in 50%. But there was without statistically any significant difference between the administration of antibiotics. 4) The occurence of bacteriuria in patients according to frequency of bladder irrigation. 50% of those patient who irrigated twice a day developed bacteriuria, 63.6% of those patient who irrigated once a day developed bacteriuria. The occurence of bacteriuria in patients were significant differences at 1% level between frequency of bladder irrigation. 5) The occurence of bacteriuria in patients who did perineal care once a day was 58.1%, 22.6% of those patient who did perineal care twice a day developed bacteriuria. But there was without statistically any signiticant differences between frequency of perineal care. 6) Most frequent bacteria of all bacterial strains isolated by culture of the urine was E. coli(45%). Enterococci & Staphylococcus were 15% respectively.
Microbial infection provokes one of the most serious complications to the patients with indwelling catheters. Ciprofloxacin (CFX) was added into the catheter materials (polyurethane or silicone) during the manufacturing process to avoid the microbial infection. Efficacy of the catheters containing CFX was investigated by using the in vitro zone of growth inhibition test method. The catheters made of polyurethane or silicone exhibited a strong antimicrobial activity against the major catheter-related microorganisms (S. aureus, S. epidermidis, P. aeruginosa and E. coli), when CFX was incorporated into the catheters. Fetal bovine serum (FBS) did not affected antimicrobial activities of the polyurethane catheters with CFX loading of 0.5 and 1.0% (W/W) against S. aureus and S. epidermidis. However, the polyurethane catheters with 1.0% (W/W) of CFX loading showed a significantly (P<0.05) reduced antimicrobial activity against E. coli when the catheters were exposed to FBS. Silicone catheters with 1.0 and 1.5% (W/W) of CFX loading demonstrated effective antimicrobial activity against S. epidermidis for at least 2 weeks. These results suggest that the use of catheters containing ciprofloxacin could be effective in preventing catheter-related infections.
