Decision-making around removal of indwelling urinary catheters after pituitary surgery.

BACKGROUND: Diabetes insipidus (DI) is a common complication following pituitary surgery, causing significant health issues if left untreated. As part of the diagnostic process, accurate urinary output monitoring via indwelling urinary catheters (IDUCs) is essential, despite risks such as urinary tract infections and hindered recovery. Research on IDUC removal after pituitary surgery remains scarce. AIM: To explore health professionals' perspectives on IDUC management following pituitary surgery. METHODS: Employing a qualitative design, semistructured interviews were conducted with 15 professionals in the neurosurgical ward of a Dutch academic hospital. FINDINGS: Four themes emerged: Concerns about missing identifying DI, patient-nurse dynamics, workload management, and lack of shared decision making. CONCLUSION: The findings underscore the need to balance clinical needs with patient care efficiency. There is a need for evidence-based guidelines and a multidisciplinary approach to optimise IDUC management, given the importance of patient-centred care and shared decision-making.

Effects of dietary habits and catheterization type on breast cancer-related lymphedema: a retrospective cohort study.

BACKGROUND: Understanding the factors that contribute to variability in breast cancer-related lymphedema (BCRL) is an important first step in developing targeted interventions to improve quality of life in breast cancer patients. Although previous research studies have has identified many risk factors for BCRL, dietary habits and catheterization type have rarely been studied until the present. AIM: This study aims to explore the effects of nursing factors such as dietary habits and catheterization type on breast cancer-related lymphedema (BCRL). METHODS: This retrospective cohort study included 1,476 breast cancer patients who underwent surgery between January 1, 2012, and September 1, 2020. Lymphedema was assessed with a validated self-report questionnaire. All research data were obtained from medical records and a follow-up database. Multivariate Cox regression was conducted to explore the effects of dietary habits and catheterization type on BCRL. RESULTS: The results showed an increased risk for BCRL among breast cancer patients who followed a high-fat diet prehospitalization (HR = 2.47; 95% CI = 1.55-3.94; P < 0.001), indwelling totally implantable venous access ports (TIVAPs) compared with indwelling needles (HR = 0.56; 95% CI = 0.35-0.90;P = 0.017) or indwelling peripherally inserted central catheters (PICCs) (HR = 0.69; 95% CI = 0.45-1.05; P = 0.086). CONCLUSION: High-fat diet pre-hospitalization was an independent risk factor for lymphedema. The TIVAPs did not exert a protective effect on lymphedema compared with the PICC and indwelling needle. This study finding offers new insights to develop targeted interventions to decrease the incidence of lymphedema.

Complications associated with the removal of totally implantable venous access devices (TIVADs): a retrospective analysis of 4,954 breast cancer patients in a single institution.

BACKGROUND: Totally implantable venous access devices (TIVADs) have been widely used for many years in the management of cancer patients. However, previous studies have rarely focused on the period surrounding TIVAD removal, which is a critically important phase for these devices. This study aims to address this gap by investigating the surgical approaches, timing, and associated complications related to the removal of TIVADs, thereby enhancing the management of these devices. METHOD: A retrospective analysis was conducted on a cohort of 4,954 TIVAD extraction procedures performed at the Breast Center of the Fourth Hospital of Hebei Medical University between January 1, 2016, and August 1, 2023. RESULTS: Among 4,954 cases, the indwelling time of TIVADs for included patients ranged from 2 to 60 months. 4,882(98.5%) cases removed their TIVADs after completion of cancer treatment, while 72 cases (1.5%) were unplanned removal due to TIVADs related complications. Two surgical techniques were observed for port removal: in 20% of cases, the injection port was removed first, followed by the catheter; in 80% of cases, the catheter was removed first, followed by the injection port. Complications during TIVADs removal were observed in 13 cases (0.3%) including 2 cases of bleeding, 5 cases difficulty in removal of the port and catheter, and 6 cases representing of delayed wound healing. Longer indwelling time tended to have higher risk of developing catheter rupture and fracture. CONCLUSION: This study provides valuable insights into the removal of TIVADs in cancer patients. Complications during removal were uncommon but included bleeding, difficulty in removing the port and catheter, and delayed wound healing. Additionally, longer indwelling times were associated with an increased risk of catheter rupture and fracture, highlighting the need for careful monitoring and timely removal of TIVADs to minimize potential complications. The findings of the study underscore the importance of optimizing TIVAD management, particularly during the removal phase, to improve patient outcomes.

Percutaneous transluminal angioplasty is safe and feasible for reinsertion of tunneled cuffed catheters in the right internal jugular vein.

This study explores the feasibility, safety, and efficacy of percutaneous transluminal angioplasty (PTA) for reinserting tunneled cuffed catheters (TCC) with a Dacron sheath in the right internal jugular vein (RIJV) in hemodialysis patients with a history of prior RIJV catheterization and subsequent stenosis or occlusion of the RIJV, right innominate vein, and superior vena cava. Clinical data from 21 hemodialysis patients with dysfunctional vascular access who underwent PTA for reinsertion of TCC in the RIJVs from July 2020 to June 2023 at the First and Second Affiliated Hospitals of Bengbu Medical College were retrospectively analyzed. Clinical efficacy during hospitalization, postoperative TCC blood flow, and related complications during follow-up were observed. The procedure was successful in all 21 patients, with postoperative TCC blood flow meeting daily hemodialysis requirements. Only one case experienced acute bleeding with contrast agent extravasation at the intersection of the left and right innominate veins during sharp recanalization. No severe complications, such as arrhythmias, vascular rupture, pneumothorax, mediastinal hematoma, or pericardial tamponade, occurred during the procedures. Upon discharge, all patients exhibited satisfactory TCC blood flow (247.14 ± 11.46 ml/min). Postoperatively, TCC blood flow ranged between 200 and 260 ml/min, meeting the demands of regular hemodialysis. For patients with a history of repeated TCC or non-tunneled catheter (NTC) placement in the RIJV, reinserting TCC in the RIJVs through PTA is a safe and reliable technique. It effectively utilizes vascular resources and prevents vascular resource depletion associated with changing the venous catheter placement location.

A case report on the choice of venous access after ectopic peripherally inserted central catheter in an upper limb of a patient with a second recurrence of right-side breast cancer.

RATIONALE: Intravenous catheter placement in the healthy upper extremity is preferred for chemotherapy in patients with breast cancer. Common venous accesses are peripherally inserted central catheters (PICCs) and totally implantable intravenous port catheters (TIVPs). In this case, a patient with breast cancer had a history of infusion port placement through the left internal jugular vein, with ipsilateral innominate vein stenosis after placement. The patient was re-treated with a PICC placed ectopically through the left upper limb into the intrathoracic vein. After multidisciplinary consultation, a transfemoral PICC combined with intracavitary electrocardiography (IC-ECG) was performed to establish venous access. This case can assist PICC catheterization nurses in developing optimal venous access strategies tailored to the specific situations of patients in similar situations. Through adequate evaluations and optimal selection of venous access, the success rate of disposable catheterization can be improved, and the risk of complications reduced. PATIENT CONCERNS: A 53-year-old female with breast cancer had a history of infusion port, with ipsilateral innominate vein stenosis after placement. The patient was re-treated with a PICC placed ectopically through the left upper limb into the intrathoracic vein. DIAGNOSES: An axial computed tomography (CT) image before totally implantable venous access port (TIVP) placement and An axial CT 103 days after TIVP placement shows diffuse stenosis of the left innominate vein, associated with infusion port placement through the left internal jugular vein. INTERVENTIONS: After multidisciplinary consultation, a transfemoral PICC combined with intracavitary electrocardiography (IC-ECG) was performed to establish venous access. OUTCOMES: The patient's lower limb PICC was left in place for 201 days with no complications, completing the full treatment cycle. LESSONS: This case presents a rare and insightful clinical scenario. For patients with a history of infusion port placement, particularly via the left internal jugular vein, careful analysis of the innominate vena cava and examination of chest wall vein exposure are essential to determining the optimal vascular access strategy.

11 cases of peritoneal dialysis catheter penetrating into the intestinal cavity: case series.

The penetration of a peritoneal dialysis catheter into the intestinal cavity is a clinically rare complication. In the present retrospective clinical case series, 11 patients with uraemia who received continuous ambulatory peritoneal dialysis and attended hospital between 2019 and 2023 are described. The median patient age was 61.91 ± 11.33 years. All patients had previously experienced peritoneal dialysis-related peritonitis and were clinically cured by infusing sensitive antibiotics into the abdominal cavity. Colonoscopy was utilised to locate the penetrating catheter and close the perforation with a titanium clip once the catheter had been removed via an external approach. Following a 2-4-week fast, the perforations healed in all 11 patients. The present authors' experience illustrates that directly removing the catheter and clamping the perforation opening under the guidance of colonoscopy is simple to operate with few complications compared with traditional open surgery.

Urothelial carcinoma associated with a long-term indwelling cystostomy component of a subcutaneous ureteral bypass device in a domestic shorthair cat.

Urothelial carcinoma (UC) occurs uncommonly in cats and no association has previously been observed with long-term indwelling urinary implants. An 18-year-old male castrated domestic shorthair cat initially was presented for hematuria, leading to the diagnosis of a right-sided ureterolithiasis and severe pyelectasia on ultrasound examination, prompting right-sided subcutaneous ureteral bypass (SUB) device placement. The cat subsequently had intermittent hematuria and dysuria, without ultrasonographic abnormality of the bladder or positive urine culture. Thirteen months later the patient developed refractory lower urinary tract signs, azotemia, a proliferative mass in the region of the cystostomy tube component of the SUB device and evidence of left ureteral obstruction. Cystostomy tube revision and left-sided SUB device placement were performed, as well as a partial cystectomy for removal of the mass. Upon histopathology, the mass was diagnosed as a UC. To our knowledge, UC associated with a long-term indwelling cystostomy catheter component of a SUB device has not been reported in veterinary medicine.

Difficult Removal of a Stuck Chemoport Catheter of a Paediatric Patient in Post-Coronavirus Disease (COVID-19) Era - Management Strategies and Literature Review.

ABSTRACT: A chemoport is widely used in paediatric oncology population. Removal is a relatively easy procedure, but difficulty can be encountered in case the catheter is densely adherent to the vascular wall. It is a rare complication and is associated with long indwelling duration and acute lymphoblastic leukaemia (ALL). Forceful traction can lead to vascular injury and high morbidity. Herein, we report a 7-year-old girl with precursor B ALL who had delayed chemoport removal due to the coronavirus disease (COVID-19) pandemic. The removal process was difficult, as the catheter was adherent to the right innominate vein. Out of panic, the surgeon pulled it out forcefully. Fortunately, the catheter and its fragment were successfully retrieved completely and the child was discharged the next day. The management strategy varies and ranges from minimally invasive to open surgery. Leaving a stuck chemoport catheter in situ can be a bailout method or part of conservative management.

[SOP Management of Port Infections]. / SOP Management von Portinfektionen.

Port systems provide safe venous access for patients with poor venous status and are essential for the long-term administration of drugs such as chemotherapeutics. However, they are not without complications. Port infection is a life-threatening situation; the infection rate in current studies varies from 0.8% to 7.5% and is significantly higher in cancer patients at 16-31%. The purpose of this SOP is to provide an overview of the management of port infections.

Aetiology and management of persistent withdrawal occlusion in venous ports in oncology patients.

INTRODUCTION: Persistent withdrawal occlusion (PWO) is a specific catheter malfunction characterized by the inability to withdraw blood through the device. The most common cause of PWO in ports is the presence of a fibroblastic sleeve (FS). If malfunction occurs, medication can be applied incorrectly with the increased risk of complications. METHODS: One hundred seventy-seven cases of PWO in venous ports were managed. We focused on evaluating the cause of PWO, the frequency of occurrence of FS, and the options to address the malfunction. The patients underwent fluoroscopy with a contrast agent administration. Mechanical disruption (MD) with a syringe of saline using the flush method was used; in case of its failure, subsequent administration of a lock solution with taurolidine and urokinase, or low-dose thrombolysis with alteplase was indicated. Demographic data were compared with a control group. RESULTS: A significantly higher proportion of female patients was found in the cohort of patients with PWO (80.3% vs 66.3%, p = 0.004), dominantly patients with ovarian cancer (12.8% vs 4.8%, p = 0.022). No effect of the cannulated vein or the type of treatment on the incidence of PWO was demonstrated. The presence of FS was verified in 70% of cases. MD with a syringe was successful in 53.5% of cases. A significantly shorter time to referral (3 weeks) was demonstrated with successful management. The overall success rate of achieving desobliteration by MD alone or in combination with a thrombolytic (urokinase or alteplase) administration was 97.4%. CONCLUSION: We created a method for resolving PWO using MD +/- application of thrombolytics with 97.4% success rate. Current evidence showed that FS is not likely to be affected by thrombolytic drugs; however, we have ascertained an effect of these drugs, proposing a hypothesis of microthrombotic events at the tip of the catheter if fibroblastic sleeve is present.

A modified open surgical revision technique for malfunctioning peritoneal dialysis catheter.

Backgrounds: The malfunction of peritoneal dialysis (PD) catheter is still an intractable problem. A modified open surgical revision technique with suturing fixation and without catheter removal for malfunctioning catheter was developed to evaluated the efficacy and safety between simultaneous catheter replacement technique.Methods: A total of 167 PD patients with malfunctioning catheter were retrospectively reviewed. For the salvage of PD catheters, patients underwent modified open surgical revision (group A) or simultaneous catheter replacement (group B). The baseline characteristics before operation, perioperative condition, complications and outcomes were compared between both groups.Results: Patients of group A showed significantly shorter operative time (67.4 ± 22.1 versus 82.8 ± 21.1 min, p = 0.009), less postoperative pain score within 24 h (median 0.0 versus 2.0, p < 0.001), quicker start of PD (1.06 ± 0.31 versus 1.89 ± 0.89 days, p < 0.001), shorter length of stay (9.89 ± 5.11 versus 12.55 ± 7.37 days, p = 0.020) than group B. In terms of complications, the incidence of recurred catheter malfunction in group A was significantly lower than those in group B (1/114 versus 12/53, p < 0.001). There were no significant differences in mechanical complications (bloody effluent, dialysate leakage, and hernia) and early peritonitis between the groups. The group A patients had a favorable catheter survival rate compared with group B (log-rank, p = 0.004).Conclusions: Our modified open surgical revision technique is a safe, simple and fast method, and offers a better outcome with minimal risk of recurrence of catheter malfunction without additional cost and equipment. This technique is worthy of clinical application.

Infection rates during eras of intrathecal antibiotic use followed by antibiotic-impregnated catheter use in prevention of cerebrospinal fluid shunt infection.

OBJECTIVE: The Hydrocephalus Clinical Research Network (HCRN) implemented a perioperative infection prevention bundle for all CSF shunt surgeries in 2007 that included the relatively unproven technique of intrathecal instillation of the broad-spectrum antibiotics vancomycin and gentamicin into the shunt. In the meantime, the field debated the use of antibiotic-impregnated catheter (AIC) shunt tubing using clindamycin and rifampin, an increasingly widespread, but expensive and controversial, technique. It is unknown whether there were changes in infecting organisms associated with the use of these techniques during CSF shunt surgery at the hospital level. Key comparison periods include during the use of intrathecal antibiotics (period 1 from June 1, 2007, to December 31, 2011, at HCRN hospitals) and AIC (period 2 from January 1, 2012, to December 31, 2015, at HCRN as well as increasing over time at non-HCRN hospitals) and only standard use of routine prophylactic antibiotics (period 1 at non-HCRN hospitals). The aim of this study was to examine rates of CSF shunt surgery-related infections from 2007 to 2012 at the hospital level, including HCRN and non-HCRN hospitals, with a focus on infections with gram-negative organisms. METHODS: The authors conducted a retrospective observational cohort study at 6 children's hospitals with enrollment from 2007 to 2012 and surveillance through 2015. Bimonthly rates of shunt surgery-related infections were summarized to produce an overall hospital-specific time series, as well as by HCRN/non-HCRN status. An interrupted time series analysis was performed to assess the impact of change in HCRN perioperative infection prevention bundle on overall bimonthly infection rates. Quarterly rates of gram-negative shunt surgery-related infections were summarized to produce an overall hospital-specific time series. RESULTS: The overall bimonthly CSF shunt infection rate over time did not change significantly from 2007 to 2012. There was no difference in the trajectory of infection rates between HCRN and non-HCRN hospitals during the entire study period. No change in distributions of gram-negative organism infections was observed in hospitals from 2007 to 2015. CONCLUSIONS: There were no differences observed in hospital-level infection rates for low-risk patients undergoing CSF shunt surgery. This included analyses based on participation in the HCRN network, given their regular use of intrathecal antibiotics in period 1 and a focus on gram-negative infections with increasing adoption of AICs in period 2.

Indwelling-tunneled-central-venous-catheter-related early bacteremia and preoperative prophylaxis: a case and control study. / Bacteriemia precoz asociada a catéter venoso central tunelizado permanente y profilaxis preoperatoria: estudio de casos y controles.

INTRODUCTION: The indication of preoperative prophylaxis in the insertion of indwelling tunneled central venous catheters (ITCVC) has a low level of evidence. Our objective was to assess risk factors of ITCVC-related early bacteremia in oncological pediatric patients and to determine the need for preoperative prophylaxis. MATERIALS AND METHODS: A univariate and multivariate retrospective analysis of patients in whom an ITCVC was placed from January 2020 to July 2023, according to whether they had ITCVC-related early bacteremia (EB) in the first 30 postoperative days, was carried out. Demographic variables, leukopenia, neutropenia, use of preoperative antibiotic prophylaxis, and history of central venous catheter (CVC) or bacteremia were collected. Calculations were carried out using the IBM SSPS29® software. RESULTS: 176 patients with a mean age of 7.6 years (SD: 4.82) were analyzed. 7 EB cases were identified, with a greater frequency of neutropenia (p= 0.2), history of CVC in the 48 hours before insertion (p= 0.08), and intraoperative CVC (p= 0.04). The presence of intraoperative CVC increased the risk of EB 9-fold [OR: 9.4 (95%CI: 1.288-69.712) (p= 0.027)]. The lack of preoperative prophylaxis did not increase the risk of EB [OR: 2.2 (CI: 0.383-12.669) (p= 0.3)]. The association with other variables was not significant. CONCLUSIONS: The intraoperative presence of CVC was a risk factor of EB in our patients. Preoperative prophylaxis had no impact on the risk of EB, which in our view does not support its use. However, further studies with a larger sample size are required. Leukopenia or neutropenia at diagnosis were not associated with a greater prevalence of infection.

INTRODUCCION: La indicación de profilaxis preoperatoria en la colocación de catéteres venosos centrales tunelizados permanentes (CVCTP) tiene bajo nivel de evidencia. Nuestro objetivo fue evaluar factores de riesgo de bacteriemia precoz asociada a CVCTP en pacientes pediátricos oncológicos y determinar la necesidad de profilaxis preoperatoria. MATERIAL Y METODOS: Realizamos un análisis retrospectivo univariante y multivariante de los pacientes con colocación de CVCTP entre enero 2020 y julio 2023, en función de si presentaron bacteriemia precoz (BP) relacionada con CVCTP en los primeros 30 días postoperatorios. Recogimos variables demográficas y otras como: leucopenia, neutropenia, uso de profilaxis antibiótica preoperatoria y antecedente de catéter venoso central (CVC) o bacteriemia. Los cálculos se realizaron mediante el software IBM SSPS29®. RESULTADOS: Analizamos 176 pacientes, con edad media de 7,6 años (SD 4,82). Identificamos 7 casos de BP, que presentaron mayor frecuencia de neutropenia (p=  0,2) y antecedente de CVC las 48h previas a la colocación (p=  0,08) y CVC intraoperatorio (p=  0,04). La presencia de CVC intraoperatorio aumentó 9 veces el riesgo de BP [OR 9,4 (IC 95% de 1,288-69,712) (p=  0,027)]. La falta de profilaxis prequirúrgica no aumentó el riesgo de BP [OR 2,2 (IC 0,383-12,669) (p=  0,3)]. La relación con otras variables no fue significativa. CONCLUSIONES: La presencia intraoperatoria de CVC fue factor de riesgo de BP en nuestros pacientes. La profilaxis preoperatoria no influyó sobre el riesgo de BP, por lo que creemos que su empleo no está justificado, aunque se necesitarían más estudios con mayor tamaño muestral. La leucopenia o neutropenia al momento diagnóstico no se relacionaron con mayor prevalencia de infección.

Guidewire entrapment in the Chiari network during the insertion of a hemodialysis catheter: a case report.

BACKGROUND: The Chiari network, a remnant of fetal anatomy, consists of a mesh-like structure within the right atrium. With advancements in cardiac interventions, complications associated with the Chiari network have increasingly been reported. However, there are few reports about guidewire or catheter entrapment in the Chiari network during the insertion of a dialysis catheter. CASE PRESENTATION: A 46-year-old male with end-stage renal disease was hospitalized and underwent a digital subtraction angiography-assisted catheterization of the right internal jugular vein tunnel-cuffed dialysis catheter. When the guide wire entered a depth of about 20 cm, it was difficult to advance, manifested as resistance when twisting the guide wire and inability to enter the inferior vena cava. After the peelable sheath was inserted, it was difficult to pull out the guide wire. After repeated attempts to rotate the guide wire, the guide wire was finally pulled out. A fibrous tissue was wrapped around the tip of the guide wire. Its length was 6 cm, with a smooth surface and tough texture. We considered that the tissue we pulled out was most likely a part of a Chiari network. CONCLUSIONS: This case highlights the potential for the Chiari network to complicate surgical procedures, including difficulty with guidewire and catheter manipulation. Attention should be paid to Chiari networks. Echocardiography can be used to identify the Chiari network. During the surgery, forcefully pulling out a stuck guidewire is not suggested, to avoid the risk of tearing the atrial wall and causing pericardial tamponade. An urgent consultation with ultrasound doctors and cardiac surgeons might be helpful in such cases.

Surgical procedures and complications in placement of totally implantable venous access port in pediatric hemophilia patients: A retrospective analysis.

This retrospective study at Beijing Children's Hospital (2020-2023) analyzed surgical procedures and complications in 24 pediatric hemophilia patients undergoing Totally Implantable Venous Access Port (TIVAP) insertion, primarily in the right jugular vein (RJV). We detailed the surgical process, including patient demographics and intraoperative imaging use. The choice of the RJV for TIVAP placement was influenced by its larger diameter and superficial anatomical position, potentially reducing risks like thrombosis and infection. Our findings support the RJV as a safer alternative for port placement in pediatric patients, aligning with current literature. Statistical analysis revealed no significant correlation between complications and baseline characteristics like weight and diagnosis type. However, the length of hospital stay and implant brand were significant risk factors for catheter or port displacement and removal. The limited patient number may introduce bias, suggesting a need for further studies with larger samples. Despite a 14.7 %-33 % complication rate and 5 port removals, the advantages of TIVAP, including reliable venous access, reduced discomfort, and treatment convenience, were evident. Most complications improved with symptomatic treatment, and there were no deaths due to port-related complications, underscoring the impact of TIVAP on improving pediatric hemophilia treatment.

Ascites Is a Poor Prognostic Factor in Advanced Pancreatic Adenocarcinoma and May Be Undertreated: A Prospective Cohort Study.

INTRODUCTION: Pancreatic ductal adenocarcinoma is associated with significant morbidity and mortality as most patients present with advanced disease. The development of ascites has been associated with poor outcomes and further characterization and contemporary management strategies are needed. METHODS: A total of 437 patients enrolled in the Gastrointestinal Biobank at Cedars-Sinai Medical Center who had epithelial pancreatic malignancy were included in the prospective cohort group. Overall, 41.7% of patients included in this study developed ascites. Most patients with ascites (>80%) had high serum-ascites albumin gradient ascites. In both univariate and multivariate analysis, a history of ≥1 form of chemotherapy was significantly associated with ascites. Estimated median overall survival in patients with ascites was significantly lower than in patients without ascites, 473 days vs 573 days, and ascites had a hazard ratio of 1.37. RESULTS: Patients with ascites who received diuretics and indwelling peritoneal catheter had an estimated median survival of 133 days from diagnosis of ascites, and those who received only the indwelling peritoneal catheter without diuretics had an estimated median survival of only 54 days. The estimated median survival from the diagnosis of ascites was 92 days, and the median time to puncture was 7 days. The median time from first tap to death was 45 days. DISCUSSION: The use of diuretics is lower than would be expected for patients with pancreatic ductal adenocarcinoma with elevated serum-ascites albumin gradient. Other therapies such as beta blockers should be investigated in this subset of patients. The etiology of ascites in these patients is poorly understood, and further research is needed to establish treatment guidelines and improve outcomes.

Multidisciplinary Development and Implementation of a Trial of Void Algorithm to Standardize and Reduce Indwelling Urethral Catheter Use.

INTRODUCTION: Prolonged indwelling catheter use is a known risk factor for catheter-associated UTIs (CAUTIs). We sought to reduce catheter use by creating and implementing a trial of void (TOV) algorithm to standardize indwelling Foley catheter removal in surgical patients. METHODS: We partnered with the Departments of General Surgery and Nursing to develop an evidence-based TOV algorithm for a step-down unit at a large urban teaching hospital. Our cohort included patients treated with intra-abdominal, thoracic, vascular, urologic, and gynecologic surgeries. The primary outcome was mean cumulative indwelling urethral catheter patient-days. For example, if 2 patients had catheters for 3 and 7 days, respectively, then cumulative catheter days would be 10. We analyzed changes in catheter use 90 days before and after algorithm implementation. RESULTS: The mean number of hospitalized patient-days before and after algorithm introduction did not differ (32.2 vs 32.0, P = .60). After implementation, mean cumulative catheter patient-days decreased (14.8 vs 9.9, P < .01), as did mean daily number of patients with catheters on the unit (3.7 vs 3.1, P = .02). There was 1 CAUTI before and after algorithm implementation, the latter deemed associated with algorithm nonadherence. Catheter use in a surgical floor control group where the algorithm was not implemented did not differ for any outcome over the same time period (P > .05). CONCLUSIONS: A multidisciplinary approach to standardize catheter care with a TOV algorithm is feasible and effective in reducing catheter use. Further research is needed to determine its impact on CAUTI rate.

Antibiotic impregnated catheters and intrathecal antibiotics for CSF shunt infection prevention in children undergoing low-risk CSF shunt surgery.

BACKGROUND: Cerebrospinal fluid (CSF) shunts allow children with hydrocephalus to survive and avoid brain injury (J Neurosurg 107:345-57, 2007; Childs Nerv Syst 12:192-9, 1996). The Hydrocephalus Clinical Research Network implemented non-randomized quality improvement protocols that were shown to decrease infection rates compared to pre-operative prophylactic intravenous antibiotics alone (standard care): initially with intrathecal (IT) antibiotics between 2007-2009 (J Neurosurg Pediatr 8:22-9, 2011), followed by antibiotic impregnated catheters (AIC) in 2012-2013 (J Neurosurg Pediatr 17:391-6, 2016). No large scale studies have compared infection prevention between the techniques in children. Our objectives were to compare the risk of infection following the use of IT antibiotics, AIC, and standard care during low-risk CSF shunt surgery (i.e., initial CSF shunt placement and revisions) in children. METHODS: A retrospective observational cohort study at 6 tertiary care children's hospitals was conducted using Pediatric Health Information System + (PHIS +) data augmented with manual chart review. The study population included children ≤ 18 years who underwent initial shunt placement between 01/2007 and 12/2012. Infection and subsequent CSF shunt surgery data were collected through 12/2015. Propensity score adjustment for regression analysis was developed based on site, procedure type, and year; surgeon was treated as a random effect. RESULTS: A total of 1723 children underwent initial shunt placement between 2007-2012, with 1371 subsequent shunt revisions and 138 shunt infections. Propensity adjusted regression demonstrated no statistically significant difference in odds of shunt infection between IT antibiotics (OR 1.22, 95% CI 0.82-1.81, p = 0.3) and AICs (OR 0.91, 95% CI 0.56-1.49, p = 0.7) compared to standard care. CONCLUSION: In a large, observational multicenter cohort, IT antibiotics and AICs do not confer a statistically significant risk reduction compared to standard care for pediatric patients undergoing low-risk (i.e., initial or revision) shunt surgeries.

Evaluation of the position of the central venous catheter tip of implantable venous access devices in the occurrence of postoperative thrombotic and non-thrombotic complications.

BACKGROUND: The position of the catheter tip of totally implantable venous access devices (TIVAD) is a risk factor for postoperative complications. The study aim was to assess the early and late complications (EC and LC) associated with the position of the catheter tip in cancer patients. METHODS: We reviewed cancer patients who had a TIVAD placed in 2020. EC (≤ 90 days), LC (> 90 days) and risk factors for TIVAD-associated complications were assessed. The vertical mismatch of the catheter tip was compared to an "ideal position" (> 10 mm below the carina and ≥ 20 mm below the right main bronchus (RMB)) using chest x-ray, post-implantation. RESULTS: 301 patients were included. Median follow-up after TIVAD implantation was 9.4 months. All TIVAD catheters were inserted via the internal jugular vein (IJV). The mean distance between the catheter tip and the carina and the RMB was 21.3 mm and 6.63 mm respectively. In total, 11.3% patients developed EC and 5.6% had LC. An association was found between the position of the catheter tip from the carina (≤ 10 mm vs. > 10 mm) and the occurrence of EC (18.3% vs. 8.6%, p = 0.01) and for the catheter insertion side (left IJV vs. right IJV) (19.1% vs. 9.0% p = 0.02). Multivariate analysis showed that left IJV catheter insertion (OR 2.76), and a catheter tip located ≤ 10 mm below the carina (OR 2.71) are significant independent risk factors of EC. CONCLUSIONS: TIVAD catheter tip located at ≤ 10 mm below the carina, and a left-side inserted catheter, are higher risk of EC.
