Choice of Catheter Size for Infants in Continuous Renal Replacement Therapy: Bigger Is Not Always Better*

Conclusions: Small size central vascular catheters display optimal rheologic performances in terms of pressures and flows particularly when the renal replacement therapy device is equipped with pumps proportional to central vascular catheters sizes, and even when relatively high blood flows are set. This is achieved at the risk of a higher hemolysis rate.

Approximately 85% of hemodialysis patients are hypertensive, but less than 30% achieve adequate blood pressure (BP) control. Reduction of volume overload is fundamental for BP control, but clinical criteria to estimate dry-weight are inaccurate. In the present study we examined the effect of dry-weight reduction with a lung-ultrasound-guided strategy on ambulatory BP in 71 clinically euvolemic hemodialysis patients with hypertension. Patients were equally randomized into an active group, following a strategy for dry-weight reduction guided by pre-hemodialysis lung ultrasound, and a control group with standard-of-care treatment.

CONCLUSIONS:: DGF was not associated with US in our cohort; however, ureteral duplication and postoperative urinoma were associated with an increased risk of graft ureteral stenosis development. PMID: 30817285 [PubMed - as supplied by publisher]

The results of preoperative ultrasound (pre-US) vein mapping for hemodialysis access creation can be affected by environmental and clinical factors, such as ambient temperature, acute illness, recent phlebotomy, and hypovolemia. These factors may inadvertently exclude otherwise viable veins as options for access creation. We hypothesized that repeating the ultrasound vein mapping immediately preoperatively after anesthesia administration (post-US) identifies additional veins not appreciated by pre-US, thereby altering the operative plan and producing more preferred accesses, particularly more forearm accesses.

Abstract BACKGROUND AND OBJECTIVE: Reliable assessment of the fluid status in hemodialysis (HD) patients is often difficult. A lung ultrasound with an assessment of the B-lines ("lung comets" (LCs)) number is a novel hydration status measure. However, the occurrence of left ventricular dysfunction may have a significant effect on pulmonary congestion and further modulate the LC number. The aim of this study was to analyze to what extent left ventricular dysfunction, pulmonary hypertension, and hypervolemia affect the occurrence of LC in a cohort of prevalent HD patients. MATERIAL AND METHODS: This c...

In total, 3116 paracentesis procedures were performed: 757 (24%) inpatients and 2,359 (76%...

​BY GREGORY TAYLOR, DO, &SCOTT LAGERVELD, DOA 54-year-old man with a significant past medical history of atrial fibrillation and congestive heart failure presented to the ED with a chief complaint of difficulty walking. He was evaluated at an outside hospital two months earlier, and was found to have methicillin-resistant Staphylococcus aureus bacteremia, lower extremity cellulitis, and acute decompensated congestive heart failure (CHF). He clinically improved over one week, his autoimmune workup was negative, and he was discharged. He failed to follow up with nephrology, cardiology, and dermatology, and st...

This report describes the case of a 15-year-old female with constitutional symptoms evolving for a year, combined with headache, nausea, and vomiting, in addition to frequent visits to emergency services and insufficient clinical examination. The patient worsened significantly six months after the onset of symptoms and developed acute pulmonary edema, oliguria, acute kidney injury, and difficult-to-control hypertension, at which point she was admitted for intensive care and hemodialysis. Initial ultrasound examination showed she had normal kidneys and stenosis-free renal arteries. The patient was still anuric after 30 days...
