Percutaneous catheter drainage in combination with choledochoscope-guided debridement in treatment of peripancreatic infection

AIM:To introduce and evaluate the new method used in treatment of pancreatic and peripancreatic infections secondary to severe acute pancreatitis(SAP).METHODS:A total of 42 SAP patients initially underwent ultrasound-guided percutaneous puncture and catheterization.An 8-Fr drainage catheter was used to drain the infected peripancreatic necrotic foci for 3-5 d.The sinus tract of the drainage catheter was expanded gradually with a skin expander,and the 8-Fr drainage catheter was replaced with a 22-Fr drainage tube after 7-10 d.Choledochoscope-guided debridement was performed repeatedly until the infected peripancreatic tissue was effectively removed through the drainage sinus tract.RESULTS:Among the 42 patients,the infected peripancreatic tissue or abscess was completely removed from 38 patients and elective cyst-jejunum anastomosis was performed in 4 patients due to formation of pancreatic pseudocysts.No death and complication occurred during the procedure.CONCLUSION:Percutaneous catheter drainage in combination with choledochoscope-guided debridement is a simple,safe and reliable treatment procedure for peripancreatic infections secondary to SAP.

Clinical analysis of central venous catheter-related infections in patients in the emergency ICU

BACKGROUND:Catheter-related infection(CRI)of the central vein is a common cause of nosocomial infection.This study was undertaken to investigate the pathogen culturing and risk factors of CRI in emergency intensive care unit(EICU)in order to provide the beneficial reference.METHODS:From January 2008 to December 2010,a total of 1 363 patients were subjected to catheterization.In these patients,the peak CRI rate of the patients was determined by bacterial cultivation and blood bacterial cultivation.RESULTS:CRI happened in 147 of the 1 363 patients using the central venous catheter.The peak rate of CRI was 10.79%,with an incidence of 3.05 episodes per 1 000 catheter days.Of the147 patients,46.94%had gram-negative bacilli,40.14%had gram-positive cocci,and 12.92%had fungi.Unconditional logistic regression analysis suggests that multiple catheterization,femoral vein catheterization,the application of multicavity catheter,and the duration of catheterization were the independent risk factors for CRI.CONCLUSION:The risk factors for catheter-related infections should be controlled to prevent the occurrence of nosocomial infection.

Reducing the Rate of Catheter-Associated Urinary Tract Infection in the Non-ICU Setting

Background: In 2008, the catheter associated urinary tract infection (CAUTI) rate at King Fahad Medical City (KFMC) was 3.8/1000 urinary catheter days with some variability between departments. KFMC is the newest tertiary, referral and teaching hospital with 1100 beds in Riyadh, Saudi Arabia. The Infection Control Department at KFMC decided to implement a quality improvement project by applying the bladder bundle in our general ward (Non-ICU) using the model of National Health Service (NHS) hospitals in England even though there was good evidence supporting this infection control practice only in ICU patients?[1][2]. Our objective was to decrease CAUTI in two non-ICU units by at least 50% in one year. Study design: This was a prospective interventional quality improvement project aiming to decrease CAUTI in two non-ICU inpatient units with a total of?193 beds including children and adult patients. Our intervention includes insertion and maintenance components. Results: CAUTI decreased significantly in both departments from 23 infections in?2008 (Rate: 5.03/1000 CDs) to 12 infections in 2009 (Rate: 1.92/1000 CDs) (P?= 0.0001);in RH (Rehabilitation hospital) from 18 in 2008 (Rate: 4/1000 CDs) to 11 infections in 2009 (Rate: 0.36/1000?CDs) (P?< 0.0001) and in NSI (National Neuroscience Institute) from 5 in 2008 (Rate: 5.42/1000?CDs) to 1 infections in 2009 (Rate: 3.16/1000 CDs) (P?< 0.0001). Conclusion: Implementation of urinarycatheter insertion and daily care bundles, and creation of a competitive spirit among employees were associated with a significant reduction in catheter associated urinary tract infections.

Catheter-Associated Bacteria Urinary Tract Infection and Antibiotic Susceptibility Pattern in a Tertiary Hospital, in Ghana

Background: This study seeks to identify the prevalence of catheter associated urinary infection and the type of bacteria that are associated with this infection, as well as the antibiotic susceptibility patterns of the organisms isolated. This would guide the choice of antibiotics when there is catheter associated urinary tract infection. Method: From 1 November 2015-31 April 2016 a cross-sectional study was conducted among patients with urinary catheter in-situ. Urine samples collected were processed and cultured on CLED agar plates. Pure colonies of isolated organism were Gram and Biochemically characterized. A disc diffusion antibiotic susceptibility determined by Kirby-Bauer disc diffusion method was performed on each uropathogen isolated. Data obtained was cleaned, analyzed and presented. Result: There were 122 study subjects of which, 73 (59.8%) were males and 49 (40.2%) were females. Their median age was 42.5 (range 33 - 65) years. Significant bacterial growth was obtained in 88 (72.1%) of the urine specimen cultured of which males constituted 48 (54.5%) and females 40 (45.5%). The most prevalent uropathogens isolated were Escherichia coli 41 (46.6%), Klebsiella spp. 18 (20.6%), Pseudomonas aeruginosa 10 (11.4%), Enterobacter spp. 6 (6.8%) and Staphylococcus aureus 5 (5.8%). Bacterial isolates showed some susceptibility to Amikacin 73 (83.0%), Levofloxacin 34 (38.6%) and Ciprofloxacin 26 (29.5%) respectively. The uropathogens were least susceptible to Gentamicin 3 (3.4%), Ampicillin 3 (3.4%) and Cefuroxime 1 (1.1%) respectively. Conclusion: Catheter associated bacterial urinary tract infection (CABUTI) is prevalent at the Tamale Teaching Hospital. Micro bacterial isolates demonstrated substantial decrease in susceptibility to antibiotics commonly used. Understanding the local antibiotic susceptibility pattern could guide the choice of antibiotics used in treating CABUTI.

Ethanol Lock Therapy as additional treatment of catheter-related bloodstream infections in pediatric patients receiving home parenteral nutrition

Background: Catheter related bloodstream infections (CRIs) are a major cause of morbidity, mortality and prolonged hospitalization in pediatric patients with home parenteral nutrition (HPN). In recent years, new prophylactic and treatment options have been evaluated to reduce the incidence of CRIs and infection related catheter removals. In children, two retrospective studies have shown the efficacy of ethanol lock treatment (ELT) in reducing the incidence of CRIs in pediatric oncology patients. However, prospective data are missing. Our aim of the present study was to evaluate prospectively the effect of ELT on the cure and recurrence rate of CRIs, duration of hospitalization and antibiotic use in HPN pediatric patients. Methods: HPN children older than three months with a clinical suspicion of a CRI were included and randomised to ELT or standard flushing treatment (heparin or taurolidine). The primary outcomes were persistence and recurrence of the bacteraemia and Central Venous Access Device (CVAD) removal. Secondary outcomes included duration of antibiotic use, duration of hospitalization and side effects. Results: Data from eight HPN children experiencing 14 suspected CRI were analysed. Seven patients had proven CRIs by positive blood cultures. Four were treated with ELT and three with their standard flushing treatment. One CRI persisted in the control group. In one single patient, bacteraemia recurred three times within 24 weeks. This patient had been enrolled in both study arms. A CVAD removal was needed in one patient because of occlusion. Conclusions: This small study showed no additional efficacy of the use of ELT on cure rate or recurrences of CRIs compared to standard therapy in HPN treated children. There were also no differences in duration of hospitalization, the use of antibiotics or CVAD removal between both groups.

Prevention of peripherally inserted central catheter-related infections in very low-birthweight infants by using a central line bundle guideline with a standard checklist

Objective:To investigate the effectiveness and feasibility of using a central line bundle(CLB)guideline with a standard checklist in the prevention of peripherally inserted central catheter(PICC)-related infections(CRIs)in very low-birth-weight infants(VLBWIs).Methods:Fifty-seven VLBWIs who underwent PICC insertion at a hospital in Qingdao,China,between November 2012 and June 2013,were monitored with the CLB guideline and a standard checklist.Fifty-three VLBWIs who underwent PICC insertion were monitored by standard hospital procedures.The incidence of CRIs was compared between the two groups.Results:The incidence of infection significantly decreased from 10.0%catheter days in the control group to 2.2%catheter days in the study group(p<0.05).The indwelling catheter time significantly increased in the study group compared to the control group(31.9±15.0days vs.24.8±7.4 days,respectively,p<0.05).Colonization infections also decreased from 6.9% catheter days in the control group to 2.2%catheter days in the study group(p<0.05).The incidence of catheter-related bloodstream infections decreased from 3.1%catheter days in the control group to 0%catheter days in the study group.Conclusion:The use of a CLB guideline with a standard checklist could be an effective and feasible protocol for preventing CRIs and prolonging indwelling catheter timein VLBWIs.

Study progress on relevant infection in central venous catheter led by parenteral nutrition of patients with tumor

With the wide application of parental nutrition(PN) and central venous catheter(CVC) to tumor patients, the relative infection led by CVC has become a common and troublesome hospital infection in clinics. During infusion, PN fluid forms a high-sugar and high-fat micro-environment around CVC, facilitating the adhesion, growth, and diffusion of pathogenic bacteria. This condition forms a bacterial biofilm(BF) consisting of one or several kinds of pathogenic bacteria. Upon formation of the film, pathogens in the BF can resist anti-bacterial drugs and immune cells, causing repeated infections of bacteria or fungi and endangering the lives of patients. In this paper, we summarize the applications of PN, characteristics of CVC infection in tumor patients, mixed BF, and related research methods to provide reference for studies of mixed BF infection of CVC.

Investigation and Analysis of the Status Quo of Prevention and Control Practices of Catheter-Line Associated Bloodstream Infections (CLABSI) in Guangxi, China

The prevention and control of catheter line-associated bloodstream infections (CLABSI) have become the key content of medical care and have become the core improvement goal of nursing quality control. However, the prevention and control status of CLABSI in hospitals of different grades in Guangxi is not clear. In this study, we aim to investigate central venous catheter (CVC) placement and disinfectant use in second and third-level hospitals in Guangxi. This survey was conducted on the second and third-level hospitals in Guangxi, China from 13th April 2021 to 19th April 2021. The results show that a total of 283 questionnaires were collected, including 206 secondary hospitals and 77 tertiary hospitals. In terms of the CVC, tertiary hospitals were able to place CVC entirely under the guidance of B-ultrasound, which was 24 (31.6%) and secondary hospitals were 26 (20.6%). In secondary hospitals, Most CVC placements were performed in operating rooms 94 (74.6%) and 65 (85.5%) on the third level hospital, but 32.5% of secondary hospitals and 48.7% of tertiary hospitals were selected at the bedside of patients in general wards, and 27.8% of the second-level hospital, 43.4% of third-level hospitals was done in general ward treatment rooms, only 61.9% of secondary hospitals and 64.5% of tertiary hospitals could fully achieve the maximum sterile barrier. In terms of skin disinfectants, only 36.0% of tertiary hospitals and 16.4% of second-level CVC-operators chose > 0.5% chlorhexidine alcohol. In conclusion, the prevention and control of catheter line-associated bloodstream infections (CLABSI) in Guangxi are not ideal. The prevention and control department should increase training, implement guidelines and standardize management to reduce the incidence of CLABSI.

Objective: To explore how the nursing quality management reduces the infection of tunneled-cuffed hemodialysis catheter (TCC). Methods: The TCC infection rate from January 1st to December 31th was used as the baseline data, and the TCC infection rate from January 2014 to December 2017 was used for annual comparison. Through the nursing quality index management mode, the TCC infection rate was compared quarterly, annually and year by year by taking the measures of joint ward checking, optimizing nursing process, analyzing the root cause of infection cases and formulating countermeasures. Results: The Centre has been implementing the management of nursing quality indicators since 2014. TCC infection rate is an important part of Quality of Nursing Index Management. The comparison between 2013 and 2014 (X2 = 4.20, P = 0.04) was P Conclusion: The nursing quality index management can effectively reduce the incidence of TCC infection.

Factors Associated with Infection of the Central Venous Catheter for Hemodialysis in Ouagadougou (Burkina Faso)

Goal: The goal is to evaluate infections associated with central venous catheters of hemodialysis (CRI) in hemodialysis patients in Ouagadougou. Patients and methods: The study was cross-sectional, from February 15th to June 30th, 2015. It was conducted in Ouagadougou (Burkina Faso). We included patients with a new central venous catheter (CVC) inserted in the hemodialysis unit. The timeout for making an arteriovenous fistula (AVF) for chronic hemodialysis in Ouagadougou may exceed six months. The CVCs used at the time of the study were made of polyurethane and non-tunneled. Sociodemographic, clinical and paraclinical data were collected and analyzed. Results: During the study period, 156 CVCs were installed in 114 patients, and the average age was 41.8 ± 17.1 years. A CRI occurred on 39 CVCs for a rate of 9.5/1000 days-catheter. The frequency of CRI was 28.4%, 20.6% and 20% respectively in femoral, jugular, and subclavian veins. The culture of the tip of the catheter was done in 21 cases. Fifteen germs have been identified: eight cases of Gram-positive cocci (53.3%) and seven cases of Gram-negative bacilli (46.7%). It was essentially staphylococci (eight cases). In univariate analysis, a period of use of the CVC in chronic hemodialysis over 10 days was significantly (p = 0.01;r = 2.91) associated with the catheter-related infection (CRI). Conclusion: The impact of the CRI was very high in our series. The associated factor in the univariate analysis was the long period of use of the CVC. The most diligent production of AVFs at the YO-UHC would contribute to a significant reduction of the CRI.

Analysis of the relationship between deep venous catheter-related infection and post-operative complications in patients receiving minimally invasive esophagectomy

Objective The aim of the study was to evaluate catheter-related infection rate(CRIR)for patients receiving minimally invasive esophagectomy(MIE),to identify the optimal catheterization approach and relationship between CRIR and post-operative complications.Methods In total,168 patients with esophageal carcinoma and undergoing MIE combined with preoperative deep venous catheterization(DVC)were analyzed in our institution(Qingdao Municipal Hospital,China),from 2014 to 2018.After completing DVC,catheter-tips together with intraductal venous blood samples were sent to the microbiology lab for bacterial strain culture.CRIR was statistically evaluated for the following clinical variables:gender,age,smoking status,drinking status,past history,tumor location,histologic grade,pathological T,N,and M category,anastomotic location,anastomotic leakage,anastomotic stricture,chylothorax,pneumonia,recurrent laryngeal nerve(RLN)injury,reflux esophagitis,catheterization site,and catheter-locking days.Results Among the 144 patients recruited in our study,105 catheters were inserted into the jugular vein and 39 catheters into the subclavian vein.The median age of these patients was 63 years(range:42–79 years),and the median catheter-locking period was seven days(range:4–21 days).Four catheters were identified with three types of strain colonizations,including Staphylococcus epidermidis,Staphylococcus aureus and Blastomyces albicans.Statistical data showed that patients diagnosed with catheter-related infection were likely to incur anastomotic leakage(66.67%,P<0.001)and pneumonia(27.27%,P<0.001);features such as tumors located in the upper esophagus(13.6%,P=0.003),and over seven catheterlocking days(10.00%,P<0.001)were attributed to a high CRIR.Conclusion Although both jugular and subclavian veins can be catheterized for patients with MIE,DVC is associated with more than seven catheter-locking days and upper esophagectomy,due to high CRIR.Furthermore,catheter-related infection is related to anastomotic leakage and pneumonia.

Incidence and Etiology of Catheter Associated Urinary Tract Infection among Admitted Patients at Kabale Regional Referral Hospital, South Western Uganda

Introduction: Catheter Associated Urinary Tract Infection is the most common hospital acquired infection worldwide. Urinary Tract Infections among catheterised patients are on rise regardless of antibiotic use and this is due to erratic use of antibiotics, treatment failure, antimicrobial resistance and emergency of Extended Spectrum Beta Lactamase producing bacteria leading to patient distress, increased healthcare costs, long hospital stay and poor patient response to antibiotics. In Uganda, no previous studies have sought to study the burden of CAUTI among catheterized patients, the bacterial pathogens involved and their antimicrobial susceptibility patterns yet there is upsurge in antimicrobial resistance of uropathogens. The effective management of patients suffering from Catheter Associated Urinary Tract infection (CAUTI) relays on the identification of uropathogens that cause CAUTI and the selection of an effective antibiotic agent to the uropathen in question. Objectives: The objectives of this study were to determine incidence, etiology and antibiotic susceptibility pattern among the uropathogens causing Catheter Associated Urinary Tract Infections among patients with indwelling catheters at Kabale Regional Referral Hospital. Methods: Using a descriptive prospective observational hospital-based study, the study was conducted on 150 catheterized patients recruited from Emergency, Obstetrics and gynecology, Medical, Maternity and Surgical wards at Kabale Regional Referral Hospital between April and May 2019. The urine samples from study participants were processed in Kabale RRH microbiology laboratory as per standard operating procedures. After isolation and identification, all the isolates were subjected to antibiotic susceptibility testing for commonly used antibiotics. Results: Following the urine culture from 150 catheterized patients, urine from 23 (15.3%) patients showed significant growth. The common bacterial isolates were Escherichia coli 12 (52%), followed by the Klebsiella pneumoniae 6 (26%), Staphylococcus aureus 3 (13%) and Pseudomonas spp. 2 (8.7%). All Gram-negative isolates were sensitive to Imipenem 20 (100%) while all S. aureus isolates (3) were 100% sensitive to Vancomycin and Cefoxitin. Isolates were sensitive to Gentamicin 20 (82.6), Ceftriaxone 16 (69.6), Ciprofloxacin 10 (43.5) and Nitrofurantoin 9 (39.1). All isolates were 100% resistant to Cotrimoxazole. 6 gram negative isolates were resistant to ceftazidime and were tested for Extended Spectrum Beta (&#223;) Lactamase (ESBL), 5 (83.3%) were identified as ESBL-producing bacteria. K. pneumonia 3 (60%) presented the highest percentage of ESBLs as compared to E. coli 2 (40%). Conclusions: The Incidence of CAUTI among patients with indwelling urinary catheters at Kabale Regional Referral Hospital is high (15.3%) and is mostly caused by E. coli and K. pneumoniae. These bacteria are resistant to most commonly used antibiotics and thus there is a need to put more emphasis on CAUTI prevention strategies and use culture and sensitivity tests before prescription of antibiotics.

Taurolock Effectively Reduces Tunneled Dialysis Catheter-Related Infection and Catheter Exchange Rates among Hemodialysis Patients

Aims: Catheter-related infection, which is one of the major side effects of the use of dialysis catheters, leads to increases in hospitalization, morbidity and mortality. Antibiotic lock is an option for reducing the incidence of these infections, but there are concerns regarding antibiotic resistance. A prior study demonstrated that Taurolock (a taurolidine lock) may reduce the rate of catheter-related infection. Methods and Material: This investigation was a prospective before-and-after study. During period one, patients continued to use a heparin lock (5000 units/ml) for 6 months. During period two, they were shifted to Taurolock (a solution of 1.35% taurolidine, 4% citrate, and 500 units/ml of heparin) for 6 months. The primary outcome was the incidence of tunneled catheter-related infection and/or catheter exchange, and the secondary outcomes were the effects of Taurolock on catheter flow rate, dialysis adequacy, and catheter malfunction rate. Results: A total of 49 patients were included in this study. During period one, the primary outcome occurred 17 times, with an incidence rate of 86.8 per 100 patient-years;during period two, the primary outcome occurred 7 times, with an incidence rate of 32.6 per 100 patient-years (incidence rate ratio: 2.65, 95% confidence interval (CI): 1.05 - 7.6, P = 0.023). There was no significant difference between the two periods with respect to mean catheter blood flow rate (P = 0.29). During period one, thrombolytic therapy (TPA) lock was indicated on 19 occasions, with an incidence rate of 97 per 100 patient-years;during period two, TPA lock was indicated on 53 occasions, with an incidence rate of 247.5 per 100 patient-years (incidence rate ratio: 0.3, 95% CI: 0.21 - 0.67, P = 0.0003). Conclusions: We demonstrated that Taurolock usage is safe and effective for the prevention of dialysis catheter-related infection and/or catheter exchange.

Background of the study: Catheter-associated urinary tract infection (CAUTI) is the most prevalent healthcare-associated infection worldwide, according to reports. Nurses are also accountable to acquire appropriate knowledge and practices of catheter care that will prevent UTI. Nurses’ knowledge is seen to be one of the most important factors in their practice. Aim of the study: To assess the nurse’s knowledge toward the prevention of catheter-associated urinary tract infection in public hospitals at Amran City. Methods: A descriptive cross-sectional study was conducted among nurses at public hospitals in Amran City, Yemen. A convenience sampling technique was of the study consisted of 93 nurses from different public hospitals that were participated in this study. Self-administered questionnaire was used to collect data from March 2021 to April 2021. Results: The distribution of nurses’ ware female 65.6%, belonged to age group between (25 to <30 years) 43.0%. The Diploma degree was the most available qualification 88.2%, 81.7% between 1 - 5 years’ experience as nurses. Knowledge regarding prevention of catheter-associated urinary tract infection was fair 72%, while 18.3% had a good. There is a significant statistical difference between knowledge level regarding prevention of CAUTI, and sex (P-value = 0.042). Conclusion: Most of nurses had fair knowledge level regarding prevention of catheter-associated urinary tract infection. Recommendations: We recommended increasing the knowledge of nursing staff through the courses training, workshop, and curriculums.

Reducing the Prevalence of Catheter-Related Infections by Quality Improvement: Six-Year Follow-Up Study

Background: Peripheral venous catheter (PVC) insertion is a crucial nursing action during life support. Several factors that increase the risk of thrombophlebitis associated with PVCs have been reported. Objective: We wish to evaluate the impact of a quality improvement regarding PVC treatment for patients with coronary heart diseases. Method: A longitudinal, quantitative observational study was carried out in 2008 and 2013 in a hospital in southern Sweden with 360 consecutive patients suffering from acute chest pain. New routines for PVC treatment were included in the hospital with daily inspection according to a checklist. A structured observation protocol was used to survey the prevalence of thrombophlebitis between 2008 and 2013. Also, we examined the relationship between the location and luminal diameters of PVCs. Results: The student’s t-test showed significant differences between 2008 and 2013 with respect to luminal diameter of PVCs (p = 0.002), prevalence of thrombophlebitis (p = 0.003) and number of days with PVC left in situ (p < 0.001). Conclusion: These findings emphasize the value of using systematic daily inspections and checklists to achieve quality and safety in patients with acute chest pain having PVC-based treatment.

Fluoroscopy Neuro-Guided Endoscopic Removal of a Lost Ventricular Catheter in Hydrocephalic Girl with Staphylococcal Shunt Infection

In the text, the authors present a successful treatment of an 8-year-old hydrocephalic girl with retained infected ventricular catheter. Altogether, there have been 56 recorded cases of intraventricular catheter migration, including only 5 of infected shunt. In the case described, the first attempt to remove the lost catheter endoscopically was unsuccessful which was the reason for an inflammation’s spread. Only by means of fluoroscopy-assisted endoscopy was it possible to remove the free-floating infected shunt drain from the lateral ventricle during another surgery. In order to prevent immediate or delayed infection complications, the authors postulate a complete removal of a retained ventricular catheter from every patient.

Effect of Cluster Nursing in Preventing Urinary Tract Infection in Postoperative Patients with Indwelling Urinary Catheter

Objective:This paper expounds and analyzes the effect of cluster nursing in preventing urinary tract infection in postoperative patients with indwelling urinary catheter.Methods:A total of 400 postoperative patients with indwelling urinary catheter,treated in Yancheng No.1 People’s Hospital in recent two years,were recruited as research subjects.The patients were equally divided into group A and group B,with 200 patients in each group,and all received routine anti-infectives.The patients in group A(200 cases)received routine nursing.On the basis of group A,cluster nursing was implemented for patients in group B(200 cases).Results:The indwelling time of urinary catheter,the disappearance time of bladder irritation symptoms,and the probability of urinary tract infection were compared between both groups,which showed that the nursing effect of group B was better than that of group A(P<0.05).Conclusion:The implementation of cluster nursing in postoperative patients with indwelling urinary catheter can improve the deficiency of routine nursing,consolidate the treatment effect,and reduce the complication rate of urinary tract infection.

Spontaneous dislodgment of a peritoneal dialysis catheter inserted using the Seldinger technique:A case report

BACKGROUND Peritoneal dialysis(PD)is an important renal replacement therapy in patients with end-stage renal disease.PD catheters remain the lifeline for patients undergoing PD.The catheter technique survival rate is considered a core PD outcome domain.CASE SUMMARY The PD catheter spontaneously dislodged in a patient undergoing PD during regular fluid exchange without pain.Abdominal computed tomography showed a tunnel infection.A double-cuff straight Tenckhoff catheter had been inserted using the Seldinger technique.Before this incident,the patient had a history of tunnel infections.We speculate that recurrent tunnel infections and catheter insertion using the Seldinger technique may have led to catheter dislodgement.CONCLUSION The present case suggests that clinicians should more rigorously assess the persistence of catheter-related infections concerning the potential complications arising from catheter dislodgement associated with the Seldinger technique.

Study of the Effectiveness of Papaver Sp. Alkaloids as Future Therapeutic Alternatives against Enterococcus Sp. Causing Hospital-Acquired Septicemic Infections

Background and Objective: In recent years, control of Enterococcus sp. It has been proven in the local medical environment to be a cause of acquired septicemia in various age groups, and medical instruments are considered an effective means of transmitting enterococcal septicemia, and catheters are at the forefront in terms of danger. Based on this risk, this study aimed to monitor the spread of Enterococcus sp., which causes blood poisoning acquired from catheters, and to compare its response to antibiotics with that of those isolated from clinical samples in children, as a first study locally. The effectiveness of alkaloids of different types of Papaver sp. In Syrian plants, they were tested against infection with this bacteria. Materials and Methods: The study dealt with two parts: The first part included collecting clinical samples from the University Children’s Hospital in Damascus/bacterial diagnostic laboratories/then isolating and diagnosing the bacteria by following a set of tests to identify the most prevalent genera and species and comparing their prevalence rate with Enterococcus. The second part;It included collecting plant samples, confirming the species taxonomically, then extracting alkaloids from plant parts (fruit, stem, Flowers), then comparing the extent of resistance of bacterial strains to antibiotics compared to the Enterococcus sp., and then confirming the antibacterial activity of the Papaver sp. alkaloids against Enterococcus sp. Result:In its first part, the study confirmed the significant contribution of the Enterococcus sp. to infections acquired from various sources, largely in catheter tip infections (9.09%) and to a lesser extent in other sources (3.7%), The second part was to confirm the effective-ness of the alkaloid extract of the Papaver sp., especially the two species Papaver syriacum, and Papaver dubium, against Enterococcus sp. with areole diameters that ranged between (15 - 26 mm) for the fruit extract and at a minimum inhibitory concentration (3.12 - 6.25 mml) and then the stem (5 - 20 mm). And the effectiveness of the Flowers extract is very weak to almost non-existent. Conclusions: The catheter and medical sources surrounding the patient constitute a dangerous source of multi-resistant Enterococcus sp., which poses a real threat to the lives of children, with new mechanisms represented by colonization of the skin and the ability to form biofilms Surfaces of medical instruments, with are resistant to a wide range of antibiotics. As an alternative and effective modern source to limit its spread in the future, the alkaloid extract of the fruits and stems of the wild Papaver sp. has proven a strong antibiotic effect, especially the two types: Papaver syriacum and Papaver dubium.

Focus on peripherally inserted central catheters in critically ill patients

Venous access devices are of pivotal importance for an increasing number of critically ill patients in a variety of disease states and in a variety of clinical settings(emergency, intensive care, surgery) and for different purposes(fluids or drugs infusions, parenteral nutrition, antibiotic therapy, hemodynamic monitoring, procedures of dialysis/apheresis). However, healthcare professionals are commonly worried about the possible consequences that may result using a central venous access device(CVAD)(mainly, bloodstream infections and thrombosis), both peripherally inserted central catheters(PICCs) and centrally inserted central catheters(CICCs). This review aims to discuss indications, insertion techniques, and care of PICCs in critically ill patients. PICCs have many advantages over standard CICCs. First of all, their insertion is easy and safe-due to their placement into peripheral veins of the armand the advantage of a central location of catheter tip suitable for all osmolarity and p H solutions. Using the ultrasound-guidance for the PICC insertion, the risk of hemothorax and pneumothorax can be avoided, as wellas the possibility of primary malposition is very low. PICC placement is also appropriate to avoid post-procedural hemorrhage in patients with an abnormal coagulative state who need a CVAD. Some limits previously ascribed to PICCs(i.e., low flow rates, difficult central venous pressure monitoring, lack of safety for radio-diagnostic procedures, single-lumen) have delayed their start up in the intensive care units as common practice. Though, the recent development of power-injectable PICCs overcomes these technical limitations and PICCs have started to spread in critical care settings. Two important take-home messages may be drawn from this review. First, the incidence of complications varies depending on venous accesses and healthcare professionals should be aware of the different clinical performance as well as of the different risks associated with each type of CVAD(CICCs or PICCs). Second, an inappropriate CVAD choice and, particularly, an inadequate insertion technique are relevant-and often not recognized-potential risk factors for complications in critically ill patients. We strongly believe that all healthcare professionals involved in the choice, insertion or management of CVADs in critically ill patients should know all potential risk factors of complications. This knowledge may minimize complications and guarantee longevity to the CVAD optimizing the risk/benefit ratio of CVAD insertion and use. Proper management of CVADs in critical care saves lines and lives. Much evidence from the medical literature and from the clinical practice supports our belief that, compared to CICCs, the so-called power-injectable peripherally inserted central catheters are a good alternative choice in critical care.
