Purpose: The aim of this study was to determine the predictive strength of students' self-efficacy, problem-solving skills, and other characteristics in performing intravenous practices and monitor phlebitis and infiltration. Methods: This cross-sectional study was carried out with 736 third and fourth-year students studying at the Health Sciences Faculties of Balikesir and Sakarya universities. The data were collected using the Self-Efficacy Scale, Problem-Solving Inventory and Catheter Care and Infiltration Monitoring Questionnaire. Results: The participants' mean Catheter Care and Infiltration Monitoring Questionnaire score significantly and positively correlated with their mean Self-Efficacy Scale score on a moderate level (r=.25; p<.001) but significantly and negatively correlated with their mean Problem-Solving Inventory score on a moderate level (r=-.21; p<.001). In other words, because a low Problem-Solving Inventory score indicates that the person's problem-solving skill is high, the Care and Infiltration Monitoring Questionnaire score increased as the problem-solving skill increased. While the Self-Efficacy Scale predicted the year of study and catheter care and infiltration monitoring variables positively, the Problem-Solving Inventory predicted the satisfaction with the profession variable negatively. Conclusion: Self-efficacy, problem-solving, liking the profession, and year of study predict success in catheter care and infiltration monitoring. For this reason, guidance may be provided in the development of a comprehensive education system toward increasing students' problem-solving skills, self-efficacy, and professional knowledge and skills.

Trousseau's syndrome is an unexplained thrombotic event that precedes the diagnosis of an occult visceral malignancy or appears concomitantly with the tumor. Upper extremity deep vein thrombosis is prevalent in patients with a central venous catheter. Furthermore, a peripheral intravenous injection may cause upper extremity deep vein thrombosis as well. However, a deep vein thrombosis has not been reported in the form of Trousseau's syndrome with a catastrophic clinical course triggered by a single peripheral intravenous injection. A 48-year-old man presented with a swollen left arm on which he was given intravenous fluid at a local clinic due to flu symptoms. Contrast computed tomgraphy scans showed thromboses from the left distal brachial to the innominate vein. The patient developed multiple cerebral infarctions despite anticoagulation treatment. He was diagnosed with stomach cancer by endoscopic biopsy to evaluate melena and had a persistently positive lupus anticoagulant. After recurrent and multiple thromboembolic events occurred with treatment, he died on day 20.

Purpose: The purpose of this study was to re-assess the replacement time intervals of Peripheral Intravenous Catheters (PICs) by investigating phlebitis rates according to the indwelling times of PICs. Methods: The study was conducted on 340 patients in S hospital by an IV team. After PIC insertion, IV team members evaluated once a day. The PICs were replaced every 96 hours, and let them in situ when the patients wanted to, in the absence of any sign of complications, from 97 hours to 153 hours. Results: Total phlebitis rate was 19.6%. There were no significantly different factors associated with the occurrence of phlebitis. The incidence rates of phlebitis were 12.6% and 7.0% before and after 72 hours of PIC insertion, and recorded zero after 96 hours. Conclusion: It would be recommendable to maintain PIC in situ for longer than 72 hours if there is no sign of complication such as phlebitis in close monitoring of PIC insertion site.

Background : Intravenous(IV) access is becoming an increasingly important part of health care today. The current drive for clinical effectiveness and cost-effective health care serves to increase the need for reliable vascular access. Venous access devices were developed to overcome problems associated with limited peripheral access and frequent venipuncture in patients with long-term therapy. Although the peripherally inserted central catheter(PICC) have become popular during recent years in USA, its procedure is rare in Korea. Purpose : The goal of this study was to analyze the PICC inserted patient data by IV CNS intervention. Method : A Total of 62 PICCs were inserted into 51 patients by the IV CNS during a 10-month period form November, 14, 2002, to October 2, 2002. Data was obtained retrospectively through chart review. Result : The patient population included 34(54.8%) men and 28(45.2%) women, with a mean age 50.6 years. The main indication for PICC placement was to access vein in poor peripheral venous status(40.3%). The mean served interval for PICC insertions was 16.7 days(range, $2{\sim}61$ days). The reasons for removal were completed therapy in 18 cases(29.0%), patient death in 13 cases(21.0%), and mechanical or functional PICC problem in 10cases(16.1%). The three PICCs removed for presumed infection, and one had only positive tip cultures(0.2%). Conclusion : PICCs are rapidly growing popularity and required an extended course of IV therapy.

Purpose : This study was performed to estimate the incidence of nosocomial sepsis and to identify the most relevant risk factors for nosocomial sepsis in high-risk very low birth weight (VLBW) infants. Methods : A retrospective review of 341 VLBW infants, admitted to the Neonatal Intensive Care Unit of the Eulji University Hospital (Daejeon & Seoul) between January 2002 and June 2009, who survived more than 72 hours was performed. The incidence, causative organisms, risk factors and prognosis of nosocomial sepsis in VLBW infants were analyzed. Results : The incidence of nosocomial sepsis was 16.1% and the onset date of nosocomial sepsis was 21.5$\pm$15.9 days (mean$\pm$SD) after delivery. Staphylococcus aureus (21.3%) was the most common organism in the patients with nosocomial sepsis in VLBW infants. The multiple logistic regression analysis showed that, gestational age [odds ratio (OR), 0.87; 95% CI, 0.83-0.91], umbilical artery catheter use for more than 5 days (OR, 2.2; 95% CI, 1.15-4.46), umbilical venous catheter use for more than 5 days (OR, 2.1; 95% CI, 1.11-4.16), peripheral arterial line use (OR, 2.1; 95% CI, 1.14-4.04) and intravenous intralipids (OR, 4.3;95% CI, 1.13-14.32) were identified as risk factors. Conclusion : The limited usage of intravascular catheter related procedures and the short providence of intravenous nutrition may decrease the incidence of nosocomial sepsis in VLBW infants.

Intravenous injection is widely used for patient treatment, including injection drugs, fluids, parenteral nutrition, and blood products, and is the most frequently performed invasive treatment for inpatients, including blood collection, peripheral catheter insertion, and other IV therapy, and more than 1 billion cases per year. Intravenous injection is one of the difficult procedures performed only by experienced nurses who have been trained in intravenous injection, and failure can lead to thrombosis and hematoma or nerve damage to the vein. Nurses who frequently perform intravenous injections may also make mistakes because it is not easy to detect veins due to factors such as obesity, skin color, and age. Accordingly, studies on auxiliary equipment capable of visualizing the venous structure of the back of the hand or arm have been published to reduce mistakes during intravenous injection. This paper is about the development of venous detection equipment that visualizes venous structure during intravenous injection, and the optimal combination was selected by comparing the brightness of acquired images according to the combination of near-infrared (NIR) LED and Filter with different wavelength bands. In addition, an image processing algorithm was derived to threshehold and making blood vessel part to green through grayscale conversion, histogram equilzation, and sharpening filters for clarity of vein images obtained through the implemented venous detection experimental module.

Intravenous injection is the most frequent invasive treatment for inpatients and is widely used for parenteral nutrition administration and blood products, and more than 1 billion procedures are used for peripheral catheter insertion, blood collection, and other IV therapy per year. Intravenous injection is one of the difficult procedures to be performed only by trained nurses with intravenous injection training, and failure can lead to thrombosis and hematoma or nerve damage to the vein. Accordingly, studies on auxiliary equipment capable of visualizing the vein structure of the back of the hand or arm are being published to reduce errors during intravenous injection. This study is a study on the performance difference according to the number of LEDs irradiating the 850nm wavelength band on a vein detector that visualizes the vein during intravenous injection. Four LED PCBs were produced by attaching NIR filters to CCD and CMOS camera lenses irradiated on the skin to acquire images, sharpen the acquired images using image processing algorithms, and project the sharpened images onto the skin. After that, each PCB was attached to the front end of the vein detector to detect the vein image and create a performance comparison questionnaire based on the vein image obtained for performance evaluation. The survey was conducted on 20 nurses working at K Hospital.

Purpose: The purpose of this study was to identify the types of venous access devices (VAD) for cancer patients and investigate the factors related to the insertions of central venous catheter (CVC) in cancer patients. Methods: The subjects were 379 cancer patients. A retrospective review of all patients who were discharged from a cancer unit from November 1st to 21st in 2008 was done using a structured questionnaire. Results: A total of 82 CVC (21.6%) was inserted among 379 patients for administering anticancer therapy. There were statistically significant differences in age, length of stay (LOS), cumulative LOS, medical department, history of CVC insertion, cancer category, and albumin level between patients using peripheral intravenous (IV) catheters and CVC. In addition, factors influencing the use of CVC were LOS (odds ratio [OR]=0.286, confidence interval [CI]=1.043-1.124), history of CVC insertion (OR=3.920, CI=0.128-0.637), albumin level (OR=1.010, CI=1.879-8.179), cumulative LOS (OR=1.010, CI=1.001-1.018), and hematological diseases (OR=4.863, CI=2.162-10.925). Conclusion: We found that central venous catheterization for anticancer therapy was minimal even though CVC was safe and effective device for IV access. It is necessary to develop a strategy to use VADs efficiently and timely for cancer patients.

Pharmacokinetics and pharmacodynamics of metoprolol, a selective beta-l blocker, were examined for 360 minutes after intravenous bolus administration of metoprolol to 6 dogs. Plasma concentration and excreted amount in the urine metoprolol were measured by liquid chromatography with fluorescence detection. PR interval and heart rate were measured by ECG monitoring. Blood pressure was monitored through intraarterial catheter in femoral artery and cardiac output by thermodilution method using Swan-Ganz catheter. To analyze the effect site concentration-response relationship, plasma concentration and pharmacological effects were simultaneously fitted to a two pharmacokinetic compartment linked to pharmacodynamic model with NONLIN program. Results are as follows. 1) The plasma concentration of metoprolol after intrvenous injection decreased biexponentially. The terminal half-life estimated was $1.33{\pm}0.40$ hours and the volume of distribution at steady state (Vdss) and the total body clearance were $1.04{\pm}0.4\;L/kg,\;6.55{\pm}2.21\;L/hr$, respectively. The central compartment volume of distribution and peripheral compartment volume of distribution were $0.35{\pm}0.14L/kg\;and\;0.69{\pm}0.34L/kg$. The renal clearance and intercompartment clearance were $0.53{\pm}0.25\;L/min\;and\;0.35{\pm}0.19\;L/min$. 2) Simulated biophase concentration-response curve shows hyperbolic relationship and the estimated concentration-effect relationship was best explained by Emax model when the prolongation of PR interval and the reduction of the heart rate were used as pharmacodynamic parameters. Emax and EC50 were estimated to be $26.3{\pm}4.7\;msec\;and\;88.8{\pm}82.3\;g/ml$ for PR interval, and $48.7{\pm}18.8\;beats/min\;and\;113.5{\pm}78.7\;ng/ml$ for heart rate, respectively. 3) The changes of cardiac output-effect site concentration relationship was best fitted by a linear model and the slope of the relationship was $0.005{\pm}0.003$. Diastolic blood pressure-effect site concentration relationship was also explained by the linear model and the slope of the relationship was $0.038{\pm}0.034$.

Purpose: We investigated the safety and efficacy of peripherally inserted central catheters (PICCs) in terminally ill cancer patients. Methods: A retrospective review was conducted on patients who underwent PICC at the hospice-palliative division of KEPCO (Korea Electric Power Corporation) Medical Center between January 2013 and December 2013. All PICCs were inserted by an interventional radiologist. Results: A total of 30 terminally ill cancer patients received the PICC procedure during the study period. Including one patient who had had two PICC insertions during the period, we analyzed a total of 31 episodes of catheterization and 571 PICC days. The median catheter life span was 14.0 days (range, 1~90 days). In 25 cases, catheters were maintained until the intended time (discharge, transfer, or death), while they were removed prematurely in six other cases (19%; 10.5/1000 PICC days). Thus, the catheter maintenance success rate was 81%. Of those six premature PICC removal cases, self-removal due to delirium occurred in four cases (13%; 7.0/1000 PICC days), and catheter-related blood stream infection and thrombosis were reported in one case, each (3%; 1.8/1000 PICC days). Complication cases totaled eight (26%; 14.1/1000 PICC days). The time to complication development ranged from two to 14 days and the median was seven days. There was no PICC complication-related death. Conclusion: Considering characteristics of terminally ill cancer patients, such as a poor general condition, vulnerability to trivial damage, and a limited period of survival, PICC could be a safe intravenous procedure.
