Introducción: El cateterismo urinario es un procedimiento frecuente y en ocasiones es utilizado por fuera de las indicaciones aceptadas para el mismo. Esto aumenta el riesgo de complicaciones vinculadas a su uso, por lo que pueden ser prevenibles. El objetivo del estudio es conocer las características del uso de cateterismo urinario en pacientes ingresados en salas de cuidados moderados de un hospital universitario del tercer nivel de atención, determinar la frecuencia, duración e indicaciones más frecuentes, así como evaluar la presencia de complicaciones asociadas al mismo Metodología: Estudio de corte transversal, realizado en salas de cuidados moderados de un hospital terciario y universitario de Montevideo, Uruguay, el 21 de diciembre de 2022. Se incluyeron pacientes hospitalizados que presentaban o presentaron catéter vesical en la presente internación y se completó la recolección de variables mediante la revisión de la historia clínica. Resultados: De 155 pacientes ingresados en salas de cuidados moderados, a 26 (16,7%) les fue colocado un catéter urinario. La mediana de edad fue 61 años, 80% eran de sexo masculino. La mediana de internación fue de 22 días. En todos los pacientes se utilizó sonda vesical y el 54% fue colocado en el Departamento de Emergencia. En el 46% de los pacientes no se encontró indicación escrita de colocación en la historia clínica. En 50% de los casos no está especificado el motivo de indicación de sonda vesical, mientras que las indicaciones identificadas más frecuentes fueron el control de diuresis (27%) y la desobstrucción de vía urinaria baja (23%). La duración de cateterismo fue de una mediana de 13,5 días, mientras que el 27% de los pacientes la usaron más de 30 días. 35% de los pacientes presentaron complicaciones vinculadas a la sonda vesical, en su mayoría no infecciosas (27%) y 15% presentaron infección urinaria. Estos pacientes tuvieron una duración de cateterismo mayor a los que no presentaron complicaciones (23 vs 10 días, p=0,411). Conclusiones: El catéter vesical fue utilizado en un porcentaje no despreciable de pacientes ingresados en salas de cuidados moderados, de forma prolongada y frecuentemente sin indicación precisa, lo cual expone a un riesgo aumentado de complicaciones vinculadas.

Introduction: Urinary catheterization is a frequent procedure and is sometimes used outside of its accepted indications. This increases the risk of complications related to its use, so they may be preventable. The objective of this study is to know the characteristics of the use of urinary catheterization in patients admitted to moderate care wards of a tertiary care university hospital, to determine the frequency, duration and most frequent indications, as well as to evaluate the presence of associated complications. Methodology: Cross-sectional study, carried out in moderate care wards of a tertiary care and university hospital in Montevideo, Uruguay, on December 21, 2022. Hospitalized patients who present or presented a bladder catheter during the present hospitalization were included, and the collection of variables was completed by reviewing the medical history. Results: Of 155 patients admitted to moderate care wards, 26 (16.7%) had a urinary catheter placed. The median age was 61 years, 80% were male. The median hospitalization was 22 days. In all patients a bladder catheter was used and 54% were placed in the Emergency Department. In 46% of the patients, no written indication for placement was found in the clinical history. In 50% of cases, the reason for indicating the bladder catheter is not specified, while the most frequent indications identified were diuresis control (27%) and lower urinary tract obstruction (23%). The duration of catheterization was a median of 13.5 days, while 27% of the patients used it for more than 30 days. 35% of the patients presented complications related to the bladder catheter, mostly non-infectious (27%) and 15% presented urinary tract infection. These patients had a longer duration of catheterization than those without complications (23 vs 10 days, p=0,411). Conclusions: The bladder catheter was used in a non-negligible percentage of patients admitted to moderate care wards, for a long time and often without a precise indication, which exposes them to an increased risk of related complications.

Introdução: O cateterismo urinário é um procedimento frequente e às vezes é usado fora de suas indicações aceitas. Isso aumenta o risco de complicações relacionadas ao seu uso, portanto, podem ser evitáveis. O objetivo deste estudo é conhecer as características do uso do cateterismo urinário em pacientes internados em enfermarias de cuidados moderados de um hospital universitário terciário, determinar a frequência, duração e indicações mais frequentes, bem como avaliar a presença de complicações associadas ao mesmo. Metodologia: Estudo transversal, realizado em quartos de cuidados moderados de um hospital terciário e universitário em Montevidéu, Uruguai, em 21 de dezembro de 2022. Foram incluídos pacientes que apresentaram ou apresentaram sonda vesical durante a internação atual e a coleta de variáveis ​​foi concluída .revisando o histórico médico. Resultados: Dos 155 pacientes admitidos em enfermarias de cuidados moderados, 26 (16,7%) tiveram um cateter urinário colocado. A idade média foi de 61 anos, 80% eram do sexo masculino. A mediana de internação foi de 22 dias. Em todos os doentes foi utilizada sonda vesical e 54% foram internados no Serviço de Urgência. Em 46% dos pacientes, nenhuma indicação escrita para colocação foi encontrada na história clínica. Em 50% dos casos não é especificado o motivo da indicação da sonda vesical, enquanto as indicações mais frequentes identificadas foram controle da diurese (27%) e desobstrução do trato urinário inferior (23%). A duração do cateterismo foi em média de 13,5 dias, enquanto 27% dos pacientes o utilizaram por mais de 30 dias. 35% dos pacientes apresentaram complicações relacionadas ao cateter vesical, em sua maioria não infecciosas (27%) e 15% apresentaram infecção urinária. Esses pacientes tiveram uma duração mais longa de cateterismo do que aqueles sem complicações (23 vs 10 dias, p=0,411). Conclusões: A sonda vesical foi utilizada em percentual não desprezível de pacientes internados em quartos de cuidados moderados, por tempo prolongado e muitas vezes sem indicação precisa, o que os expõe a um risco aumentado de complicações associadas.

Selective postmortem arterial angiography of head and neck using digital x-ray or computed tomography: A practical and rapid method to identify vascular injuries.

Identification of vascular injuries is crucial for complete postmortem evaluation and understanding of trauma deaths by the Medical Examiner. Some vascular injuries are difficult to evaluate due to challenging anatomic locations, especially in the head and neck. Documenting injuries of the facial and vertebral arteries is challenging and necessitates time-consuming dissections that can create artifacts and disfigurement. In busy medical examiner offices with a significant number of traumatic injuries, finding a creative solution to employ reliable postmortem angiography is desirable. At the Office of the Chief Medical Examiner for the State of Maryland (OCME), we created and effectively implemented a selective angiography procedure using traditional indwelling Foley catheters and water-soluble barium swallow contrast to evaluate arterial injuries using either digital radiography or computed tomography imaging modalities. This technique and imaging interpretation can be performed by a medical examiner or forensic pathology fellow after basic technical training and basic radiology training. This study outlines the technique, methods, and utilization of the procedure and describes the findings of six deaths due to vascular lesions from different injury mechanisms and disease processes and describes the ease of implementation on a broader scale in busy Medical Examiner's offices.

Septal late enhancement by cardiac CT is associated with repeat ablation in nonischemic cardiomyopathy patients.

INTRODUCTION: Scar substrate in nonischemic cardiomyopathy (NICM) patients is often difficult to identify. Advances in cardiac imaging, especially using late iodine-enhanced computed tomography (LIE-CT), allow better characterization of scars giving rise to ventricular tachycardia (VT). Currently, there are limited data on clinical correlates of CT-derived scar substrates in NICM. We sought assess the relationship between scar location on LIE-CT and outcomes after radiofrequency catheter ablation (RFCA) in NICM patients with VT. METHODS: From 2020 to 2022, consecutive patients with NICM undergoing VT RFCA with integration of cardiac CT scar modeling (inHeart, Pessac, France) were included at two US tertiary care centers. The CT protocol included both arterial-enhanced imaging for anatomical modeling and LIE-CT for scar assessment. The distribution of substrate on CT was analyzed in relation to patient outcomes, with primary endpoints being VT recurrence and the need for repeat ablation procedure. RESULTS: Sixty patients were included (age 64 ± 12 years, 90% men). Over a median follow-up of 120 days (interquartile range [IQR]: 41-365), repeat ablation procedures were required in 32 (53%). VT recurrence occurred in 46 (77%), with a median time to recurrence of 40 days (IQR: 8-65). CT-derived total scar volume positively correlated with intrinsic QRS duration (r = .34, p = 0.008). Septal scar was found on CT in 34 (57%), and lateral scar in 40 (7%). On univariate logistic regression, septal scar was associated with increased odds of repeat ablation (odds ratio [OR]: 2.9 [1.0-8.4]; p = 0.046), while lateral scar was not (OR: 0.9 [0.3-2.7]; p = 0.855). Septal scar better predicted VT recurrence when compared to lateral scar, but neither were statistically significant (septal scar OR: 3.0 [0.9-10.7]; p = 0.078; lateral scar OR: 1.7 [0.5-5.9]; p = 0.391). CONCLUSION: In this tertiary care referral population, patients with NICM undergoing VT catheter ablation with septal LIE-CT have nearly threefold increased risk of need for repeat ablation.

Combined impact of local anaesthetic infiltration through wound catheter and epidural analgesia following surgical hepatectomy: a meta-analysis.

Introduction: A meta-analysis was performed to examine the effects of wound catheter (WC) local anaesthetic infiltration (LAI) and epidural analgesia (EA) in open hepatectomy (OH). Material and methods: A systematic literature review was performed, which found 350 subjects with OH at the baseline of the studies; 159 of them were treated with WC local anaesthetic infiltration, and 191 used EA. Results: WC LAI substantially reduced the functional recovery time (MD = -0.64; 95% CI, -1.02 to -0.26, p < 0.001) and increased the pain score on the second postoperative day (MD = 0.25; 95% CI: 0.10-0.40, p < 0.001) compared to EA in OH patients. WC LAI did not vary from EA in OH patients in second postoperative opiate use (MD = -14.86; 95% CI: -32.88 to 3.16, p = 0.11) or overall complication rate (OR = 0.66; 95% CI: 0.41-1.04, p = 0.07). Conclusions: WC LAI showed a non-significant difference in opiate consumption on the second postoperative day and in the overall complication rate, compared with EA, but it showed a lower functional recovery time and higher pain score.

Urethral catheter entrapped in vesicourethral anastomotic sutures after laparoscopic radical prostatectomy successfully removed by transurethral approach.

Introduction: Urethral catheter entrapped in vesicourethral anastomotic sutures after radical prostatectomy is a relatively common complication. We herein present a novel and safe technique to remove urethral catheter. Case presentation: A 64-year-old man was diagnosed with prostate cancer. Subsequently he underwent laparoscopic radical prostatectomy. On postoperative Day 7, the patient experienced difficulty in removing the catheter, and entanglement of the suture with the urinary catheter was suspected. After conservative follow-up, a rigid endoscope was inserted into the urethra beside urethral catheter, identifying suture entanglement with the catheter. Finally, the suture was cut with scissor forceps. Conclusion: To the best of our knowledge, this is the first reported case in which scissor forceps were used to cut the entangled thread in such a complication. This case highlights a novel but simple method for difficult removal of an entrapped catheter.

Fast pleurodesis combining talc poudrage and indwelling pleural catheter for the management of recurrent malignant pleural effusions.

BACKGROUND AND OBJECTIVES: Malignant pleural effusions (MPE) are a frequent and major turning point in neoplastic disease usually leading to poor life expectancy. Improve quality of life and relieve the dyspnea are the main objectives in this palliative care setting. This can be achieved by the placement of an indwelling catheter (IPC) or talc pleurodesis ideally performed by thoracoscopy route (talc poudrage). Beside to misidentify a trapped-lung, the latter requires a prolonged hospital stay and the IPC placement does not allow a high pleurodesis rate. To overcome these drawbacks, a combination of both technique could be proposed for the management of recurrent malignant pleural effusions. Safety and efficacy of this pragmatic approach are reported. METHODS: Consecutive patients who have been managed for recurrent MPE by a combination of talc poudrage for pleural symphysis by thoracoscopy route ending with the insertion of IPC using the same thoracic point of entry. Demographic data, hospital length of stay (LOS), procedural-related complications, patients' quality of life (QoL) and success of pleurodesis were collected. Patients were followed-up for 6 months. RESULTS: The data of twenty-five consecutive patients undergoing the procedure were analyzed. Successful pleurodesis was obtained for 14/25 patients (66 %) at one month, 17/20 patients (85 %) at 3 months and 13/15 patients (86 %) at 6 months respectively. On average, the hospital LOS after the procedure was 3.24 days (IQR 1-4) with a median of 1 day. A prolonged hospitalization (>1 day) was never due to the procedure except for one patient (pneumothorax). No IPC related infection or procedure related deaths were noted. CONCLUSION: Among patients with recurrent MPE, the combination of talc poudrage symphysis by thoracoscopy route and IPC placement on the same time results in a shortened hospital LOS and higher rate of pleurodesis. Further randomized clinical trials are needed to confirm these results.

Real world risk of discontinuing oral anticoagulation after successful catheter ablation for atrial fibrillation.

Background: Many patients with atrial fibrillation (AF) discontinued oral anticoagulation (OAC) therapy after successful catheter ablation. We aimed to determine the real-world risks and consequences of discontinuing OAC use after catheter ablation for AF. Methods: Patients who underwent successful catheter ablation for AF from January 2004 to December 2020 were divided into continued long-term OAC (On-OAC, n = 1062) and discontinued (Off-OAC, n = 1055) groups. The long-term outcomes including thromboembolic events, major bleeding, all-cause mortality and major adverse cardiovascular events (MACE), were compared between the two groups. Results: The CHA2DS2-VASc score was 3.44 ± 1.12. After a mean follow-up of 37.09 months, thromboembolism risk was higher and major bleeding risk was lower in the Off-OAC than in the On-OAC group (Both log-rank P < 0.001). CHA2DS2-VASc score-stratified subgroup analysis showed similar cumulative event rates between the two groups in men and women with scores of 2 and 3 (intermediate risk for stroke), respectively, (P > 0.05), except for a higher major bleeding rate in the On-OAC group (P = 0.002). Patients at high risk for stroke (men and women with scores ≥3 and ≥ 4) had better non-thromboembolic and non-MACE results (Both log-rank P < 0.05). Conclusion: Men with a CHA2DS2-VASc score of 2 and women with a score of 3 had a relatively low incidence of stroke events after successful catheter ablation for AF and may be safe for anticoagulation cessation. Greater benefits from long-term OAC were observed in men with CHA2DS2-VASc score ≥3 and women with score ≥4.

Spontaneous spinal epidural hematoma following IV heparin and catheter-directed thrombolysis for deep vein thrombosis.

Spontaneous spinal epidural hematoma (SSEH) is a rare condition, and it usually presents with acute onset neck or back pain, progressive weakness, and other symptoms of spinal cord compression. Catheter-directed thrombolysis is one option for limbs threatened by iliofemoral venous thrombosis; other options, such as venous thrombectomy (either open or percutaneous), are also available. There are few reported cases of SSEH owing to catheter-directed thrombolysis for deep venous thrombosis (DVT). We present a case of a 65-year-old man who presented with left lower limb extensive iliofemoral DVT and received catheter-directed thrombolysis. The patient initially had rapid improvement in his symptoms with restoration of limb perfusion. However, within 6 hours of starting catheter-directed thrombolysis, the patient developed extensive SSEH and underwent emergent spinal decompression surgery with laminectomy of T11 to T12 with complete resolution of the neurological deficit. Clinicians should consider SSEH in differential diagnosis if the patient develops acute onset neck or back pain after catheter-guided thrombolysis for DVT.

Factors influencing early recurrence of atrial fibrillation among elderly patients following radiofrequency catheter ablation and the impact of different antiarrhythmic regimens.

Background: Patients with atrial fibrillation (AF) who undergo radiofrequency catheter ablation (RFCA) necessitate the administration of antiarrhythmic drugs to prevent early recurrence. The clinical outcomes among these patients may be influenced by varying antiarrhythmic regimens. Objectives: To identify the risk factors associated with early recurrence and compare the clinical outcomes among different antiarrhythmic regimens in elderly patients with AF following radiofrequency catheter ablation (RFCA) during a 3-month period. Methods: A retrospective observational study encompassed 420 elderly patients with AF following RFCA. Baseline data were collected during the initial postoperative visit and clinical outcomes were carefully monitored over a 3-month follow-up period. Logistic regression and Cox-proportional hazard regression analyses were performed to investigate the relationship between various antiarrhythmic regimens and the clinical outcomes. Results: Multivariate logistic regression analysis revealed that age (p = 0.001), left atrial diameter (p < 0.001), left ventricular diameter (p = 0.015), reactive hyperemia index (RHI) (p < 0.001), antiarrhythmic drug (p < 0.001) and hs-cTnI (p = 0.017) were independent risk factors of early recurrence. Furthermore, in cox survival regression analysis model, survival rate of early recurrence in the amiodarone group was higher than in the propafenone group (HR 2.30, 95%CI 1.17-4.53, p = 0.016) and in the sotalol group (HR 3.60, 95%CI 2.17-5.95, p < 0.001). Compared to the amiodarone group, the incidence of liver dysfunction was lower in the dronedarone group (p = 0.046) and the propafenone group (p = 0.021). The incidence of bradyarrhythmia (p = 0.003), QT interval prolongation (p = 0.035) and atrioventricular transmission block (p = 0.021) were higher in the sotalol group than in the amiodarone group. Conclusion: RHI was identified as an independent risk factor for early recurrence among elderly AF patients after RFCA. Compared to amiodarone, propafenone and sotalol exhibited an elevated risk of early recurrence. Although there was no significant difference in early recurrence between amiodarone and dronedarone, dronedarone emerged as the preferred option due to its lower frequency of adverse drug reactions than amiodarone.

An evaluation of the outcomes associated with peritoneal catheter use in neonates undergoing cardiac surgery: A multicenter study.

Objective: The study objective was to determine if intraoperative peritoneal catheter placement is associated with improved outcomes in neonates undergoing high-risk cardiac surgery with cardiopulmonary bypass. Methods: This propensity score-matched retrospective study used data from 22 academic pediatric cardiac intensive care units. Consecutive neonates undergoing Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery category 3 to 5 cardiac surgery with cardiopulmonary bypass at centers participating in the NEonatal and Pediatric Heart Renal Outcomes Network collaborative were studied to determine the association of the use of an intraoperative placed peritoneal catheter for dialysis or passive drainage with clinical outcomes, including the duration of mechanical ventilation. Results: Among 1490 eligible neonates in the NEonatal and Pediatric Heart Renal Outcomes Network dataset, a propensity-matched analysis was used to compare 395 patients with peritoneal catheter placement with 628 patients without peritoneal catheter placement. Time to extubation and most clinical outcomes were similar. Postoperative length of stay was 5 days longer in the peritoneal catheter placement cohort (17 vs 22 days, P = .001). There was a 50% higher incidence of moderate to severe acute kidney injury in the no-peritoneal catheter cohort (12% vs 18%, P = .02). Subgroup analyses between specific treatments and in highest risk patients yielded similar associations. Conclusions: This study does not demonstrate improved outcomes among neonates with placement of a peritoneal catheter during cardiac surgery. Outcomes were similar apart from longer hospital stay in the peritoneal catheter cohort. The no-peritoneal catheter cohort had a 50% higher incidence of moderate to severe acute kidney injury (12% vs 18%). This analysis does not support indiscriminate peritoneal catheter use, although it may support the utility for postoperative fluid removal among neonates at risk for acute kidney injury. A multicenter controlled trial may better elucidate peritoneal catheter effects.

New application of intestinal obstruction catheter in enterocutaneous fistula: A case report.

BACKGROUND: Enterocutaneous fistula (ECF) is an abnormal connection between the gastrointestinal tract and the skin. ECF can lead to massive body fluid loss, hypercatabolism, and malnutrition. Therefore, nutritional support plays a crucial role in managing ECFs and promoting the healing of fistulas. For nutritional support, enteral nutrition (EN) is the preferred method when gastrointestinal function is recovering. Currently, various EN approaches have been applied for different anatomical positions of the ECF. However, the effectiveness of administering EN support for treating lower ECFs still needs further exploration and improvement. CASE SUMMARY: We present the case of a 46-year-old male who underwent gastrointestinal stromal tumour resection. Six days after the surgery, the patient presented with fever, fatigue, severe upper abdominal pain, and septic shock. Subsequently, lower ECFs were diagnosed through laboratory and imaging examinations. In addition to symptomatic treatment for homeostasis, total parenteral nutrition support was administered in the first 72 h due to dysfunction of the intestine. After that, we gradually provided EN support through the intestinal obstruction catheter in consideration of the specific anatomic position of the fistula instead of using the nasal jejunal tube. Ultimately, the patient could receive optimal EN support via the catheter, and no complications were found during the treatment. CONCLUSION: Nutritional support is a crucial element in ECF management, and intestinal obstruction catheters could be used for early EN administration.

Focal pulsed field ablation in complex atrial tachycardia: First clinical experience and 1- year outcome.

BACKGROUND: Pulsed-field ablation (PFA) has become increasingly important in the treatment of cardiac arrhythmias. In addition to single-shot devices mainly used for pulmonary vein isolation, focal PFA may provide a treatment option increasing the versatility of the technique. OBJECTIVE: The study objective was to provide data on feasibility, safety and long-term outcome of focal PFA for the ablation of complex atrial tachycardia (AT). METHODS: All consecutive patients (n=34) with complex AT treated at our department between 2022 and 2023 with a focal PFA system (CENTAURI™, Galvanize therapeutics, San Carlos, USA) were included. The majority of patients (32/34 pts) had undergone at least one prior radiofrequency ablation. Established contact-force sensing catheters were used for PFA application in combination with a PFA generator. Pulse electric field (PEF) trains were conducted in a R-wave triggered manner. RESULTS: Acute procedural success was accomplished in all patients. PFA included creation of 51 linear lesions and (re)isolation of 12 pulmonary veins. Mean procedure duration was 102.7 ± 30.3 min, with a LA dwell time of 75.0 ± 24.7 min. Mean fluoroscopy duration was 8.7 ± 5.3 min. No complications occurred. After a mean follow-up of 340.9 ± 130.1 days, recurrence of any AT occurred in 15 patients (44.1%). During 9 reablations, 3 gaps in previously created linear lesions were detected whereas the majority of recurrences (n=6) was not related to previous PFA lesion creation. CONCLUSION: Focal pulsed-field ablation of complex AT substrates was safe and efficient. Acute procedural success was 100%; after one year, the majority of patients were in sinus rhythm. A minority of recurrences was caused by insufficient PFA lesion creation.

Differences in coagulation responses to vascular injury between uninterrupted dabigatran and apixaban - a clinical prospective randomized study.

BACKGROUND: The coagulation response during vascular injury with uninterrupted administration of direct oral anticoagulants (DOACs) has not been elucidated. OBJECTIVE: Our aim was to evaluate differences in coagulation responses after vascular injury between uninterrupted direct thrombin inhibitor and direct factor Xa inhibitor recipients. METHODS: Patients scheduled for catheter ablation for atrial fibrillation were randomly assigned to receive dabigatran or apixaban in this prospective, randomized, comparative, parallel-group study. Venous blood was collected three times: 180 minutes after taking the anticoagulant on the day before the procedure, before vascular punctures of the ablation procedure, and 10-15 minutes after the start of vascular punctures. RESULTS: Forty-two patients were enrolled. The prothrombin fragment 1+2 (F1+2) level, the primary endpoint, was much larger after vascular puncture in the uninterrupted dabigatran recipients (median: 83 pmol/L; interquartile range: 56-133 pmol/L) than in the uninterrupted apixaban recipients (median: 1 pmol/L; interquartile range: -3-19 pmol/L; P < 0.001). Antithrombin levels decreased after vascular puncture in dabigatran recipients, and both protein C and antithrombin levels decreased after vascular puncture in apixaban recipients. CONCLUSIONS: Unlike uninterrupted apixaban, uninterrupted dabigatran does not inhibit thrombin generation in response to vascular injury.

Peripheral intravenous catheter-induced phlebitis in a tertiary hospital of Karachi: a cohort study.

PURPOSE: This study aimed to determine the incidence of peripheral intravenous catheter (PIVC)-induced phlebitis and its predictors among adult patients hospitalized at Dow University Hospital, Karachi, Pakistan. METHODS: A sample of 258 adult patients admitted in the selected wards and planned for peripheral intravenous catheter insertion were recruited through consecutive sampling during March to May 2019. Daily follow-ups were performed to observe signs of phlebitis using a validated tool. The cohort was followed until discharge, removal of peripheral intravenous catheter, or study conclusion. RESULTS: Of 258 patients studied, 139 (53.9%) were females. A significant number of the participants 104 (40.3%) were young adults of age 20-40 years. The incidence of phlebitis was 39.1%. Tuberculosis (TB), peripheral intravenous catheter dwell time before initial assessment, administration of IV fluids, and dissatisfactory nursing care at Day 1 were associated significantly with the development of phlebitis. There was a doseresponse relationship between the catheter dwell time in hours before initial assessment and the development of phlebitis. CONCLUSION: This study found an increased incidence (39.1%) in three months of PIVC-induced phlebitis among adult patients. In addition to patient-related and PIVC-related risk factors considered in this study, PIVC-induced phlebitis is found to be significantly associated with the level of PIVC care provided by nurses. Continuous nursing education, developing standard care plans for PIVCs, and proper documentation of care are recommended.

Evaluation of a safety-engineered peripherally inserted intravenous catheter with multiple access blood control: clinician acceptability and ease of use.

AIM: Acceptability of a new safety-engineered peripherally inserted intravenous catheter (PIVC) with multiple access blood control (MBC) was evaluated in this observational study by experienced volunteer clinicians on healthy volunteers. METHODS: Clinicians and healthy volunteers were recruited for this study. Observers documented study procedures, including if there was any blood leakage from the catheter hub at various times during hub connections and disconnections and how many attempts it took a clinician to get a successful stick. Clinicians responded to yes-or-no and Likert-scale questionnaires describing their experiences with PIVC with MBC after each procedure. Questionnaire data were summarized by frequency and percent of responses; analyses were conducted using binomial statistics. RESULTS: Overall, clinicians considered PIVC with MBC to be acceptable (93.6% agreement). Clinicians were able to easily remove the catheter protective cap, insert the catheter, visualize primary and secondary flashbacks, easily remove the needle from the catheter hub and determine if the safety clip was activated after withdrawing the needle. In addition, they were able to connect or disconnect and flush extension sets. Clinicians did not have to change their insertion technique, found the catheter easy to insert, and believed the catheter would protect them from blood exposure during insertion of the catheter and subsequent hub accesses (agreement ranged from 82.3% to 98.9%). CONCLUSIONS: No blood leakage was observed from the catheter hub at any time during the procedures. Overall, clinicians found the new PIVC with MBC to be acceptable, easy to use, and functioned properly. HIGHLIGHTS: Acceptability, usability, and ease of use of a new safety-engineered PIVC with MBC was evaluated. PIVC with MBC was >93% acceptable: prevented blood exposure after multiple insertions/removals. Most clinicians (96%) achieved first stick success when using their product. PIVC with MBC was easy to use, worked properly and allowed clinicians to keep their PIVC technique.

Rapid haemostasis to achieve dressing longevity: evaluation trial results using StatSeal catheter exit site protection.

Peripherally inserted central catheters (PICCs) are vital in delivering intravenous therapy. Despite their advantages, PICCs can lead to complications such as catheter exit site bleeding, which can cause patient distress and increase infection risk. This study evaluated the efficacy of StatSeal, a topical haemostatic device, in managing PICC exit site bleeding. StatSeal uses a hydrophilic polymer and potassium ferrate to form a seal, reducing access site bleeding and minimising dressing changes. For this study, Patients were recruited at Frimley Health NHS Foundation Trust; the trial involved 177 patients with StatSeal, and shows that 99% did not require additional dressing changes within the standard 7-day period. The findings demonstrate StatSeal's effectiveness in improving patient outcomes by reducing exit site bleeding and associated complications, enhancing the efficiency of vascular access maintenance and potentially lowering associated healthcare costs. The trial emphasises the importance of innovative solutions such as StatSeal to advance PICC care and improve patient experience.

Catheter-based ablation to improve outcomes in patients with atrial fibrillation and heart failure with preserved ejection fraction: Rationale and design of the CABA-HFPEF-DZHK27 trial.

AIMS: Atrial fibrillation (AF) is common in heart failure (HF) and negatively impacts outcomes. The role of ablation-based rhythm control in patients with AF and HF with preserved (HFpEF) or mildly reduced ejection fraction (HFmrEF) is not known. The CABA-HFPEF-DZHK27 (CAtheter-Based Ablation of atrial fibrillation compared to conventional treatment in patients with Heart Failure with Preserved Ejection Fraction) trial will determine whether early catheter ablation for AF can prevent adverse cardiovascular outcomes in patients with HFpEF or HFmrEF. METHODS: CABA-HFPEF-DZHK27 (NCT05508256) is an investigator-initiated, prospective, randomized, open, interventional multicentre strategy trial with blinded outcome assessment. Approximately 1548 patients with paroxysmal or persistent AF diagnosed within 24 months prior to enrolment and HFpEF or HFmrEF will be randomized to early catheter ablation within 4 weeks after randomization or to usual care. All patients receive anticoagulation, rate control, and HF management according to current guideline recommendations. Usual care can include rhythm control in symptomatic patients. Patients will be followed until the end of the trial for the primary outcome, a composite of cardiovascular death, stroke, and total unplanned hospitalizations for HF or acute coronary syndrome. The safety outcome comprises complications of catheter ablation and death. The trial is powered for a rate ratio of 0.75 (two-sided alpha = 0.05, 1-beta = 0.8). CONCLUSION: CABA-HFPEF-DZHK27 will define the role of systematic and early catheter ablation in patients with AF and HFpEF or HFmrEF.

Mortality in Recipients of Durable Left Ventricular Assist Devices Undergoing Ventricular Tachycardia Ablation.

BACKGROUND: Left ventricular assist device (LVAD) recipients have a higher incidence of ventricular tachycardia (VT). However, the role of VT ablation in this population is not well-established. OBJECTIVES: This single-center retrospective cohort study sought to examine the impact of post-LVAD implant VT ablation on survival. METHODS: This retrospective study examined a cohort of patients that underwent LVAD implantation at Baylor St. Luke's Medical Center and Texas Heart Institute between January 2011 and January 2021. All-cause estimated mortality was compared across LVAD recipients based on the incidence of VT, timing of VT onset, and the occurrence and timing of VT ablation utilizing Kaplan-Meier survival analysis and Cox proportional hazards models. RESULTS: Post-implant VT occurred in 53% of 575 LVAD recipients. Higher mortality was seen among patients with post-implant VT within a year of implantation (HR: 1.62 [95% CI: 1.15-2.27]). Among this cohort, patients who were treated with a catheter ablation had superior survival compared with patients treated with medical therapy alone for the 45 months following VT onset (HR: 0.48 [95% CI: 0.26-0.89]). Moreover, performance of an ablation in this population aligned mortality rates with those who did not experience post-implant VT (HR: 1.18 [95% CI: 0.71-1.98]). CONCLUSIONS: VT occurrence within 1 year of LVAD implantation was associated with worse survival. However, performance of VT ablation in this population was correlated with improved survival compared with medical management alone. Among patients with refractory VT, catheter ablation aligned survival with other LVAD participants without post-implant VT. Catheter ablation of VT is associated with improved survival in LVAD recipients, but further prospective randomized studies are needed to compare VT ablation to medical management in LVAD recipients.

Effect of saline perfusion before catheter removal in patients with BPH treated with GreenLight laser photoselective vaporization of the prostate.

OBJECTIVE: To investigate the effect of saline perfusion before catheter removal in patients with benign prostatic hyperplasia (BPH) treated with GreenLight laser photoselective vaporization of the prostate (PVP). MATERIALS AND METHODS: Patients (n=200) with BPH treated with PVP were divided into perfusion (n=100) and control (n=100) groups. For the perfusion group, saline (200 mL or the maximum capacity tolerated) was irrigated into the bladder after standardized external urethral disinfection, and the catheter was removed. Catheter removal was routinely performed in the control group. Perioperative adverse events and clinical outcomes were compared between the groups. RESULTS: Patients in the perfusion group had a shorter waiting time [3 (0-4) vs. 15 (8.75-26) min; P<0.001] and a better satisfaction grade [24 (21.75-26) vs. 23 (20-25); P=0.016] for first urination than those in the control group. The perfusion group exhibited lower anxiety levels regarding first urination than the control group [1 (1-2) vs. 1.5 (1-2), respectively; P=0.012]. Urinalysis revealed that the perfusion group had significantly lower white blood cell (WBC) count than the control group on the day [25.5 (8-37.75) vs. 43.5 (24.0-64.75); P<0.001] and 2 weeks [20.5 (11-27) vs. 31.0 (20-42); P<0.001] after catheter removal. No significant differences in treatment-related adverse events were observed [perfusion (n=15), control (n=20)]. CONCLUSION: Saline perfusion before catheter removal in patients with BPH treated with PVP could shorten the waiting time for first urination, improve patient anxiety and satisfaction and reduce postoperative urinary WBC levels.

Effect of puncture position on catheter patency rate during tunnelled dialysis catheter insertion from the right internal jugular vein.

Background: No recommendations have been made regarding the puncture position during tunnelled dialysis catheter (TDC) insertion from right internal jugular vein (RIJV). We investigated the effect of puncture positioning along with other characteristics and clinical factors associated with TDCs to determine their correlation with catheter patency rate. Methods: We retrospectively reviewed TDC insertion procedures performed between January 2018 and December 2020 at a single institution. Patients were monitored for at least 1 year or until TDC removal or replacement. The distance on the post-operative chest radiography were measured to determine the height of puncture position. End points were freedom from catheter dysfunction. Results: Total 949 catheters met the eligibility criteria. Catheter dysfunction occurred in 233 patients and catheter infection in 127 patients. By multivariate analysis, female sex [hazard ratio (HR) =1.497, 95% confidence interval (CI): 1.119-2.002; P=0.007] and split-tip catheter (HR =1.453, 95% CI: 1.087-1.944; P=0.012) were associated with an increased rate of catheter dysfunction. Every 10-year increment in age (HR =1.243, 95% CI: 1.123-1.376; P<0.001) and every 1-cm increase in the height of the catheter insertion site (HR =1.270, 95% CI: 1.096-1.473; P=0.001) were also associated with an increased rate of catheter dysfunction. After classifying the height of puncture position into 3 groups, significant worse patency was observed in the catheter with puncture height more than 4 cm (P=0.025). No immediate complications were observed. Conclusions: TDC insertion at a high puncture site correlates with an increased risk of catheter dysfunction. Puncturing the RIJV close to the clavicle is safe and enhances catheter patency.
