Background Cerebral and myocardial hypoperfusion occur during hemodialysis in adults. Pediatric patients receiving chronic hemodialysis have fewer cardiovascular risk factors, yet cardiovascular morbidity remains prominent. Methods We conducted a prospective observational study of pediatric patients receiving chronic hemodialysis to investigate whether intermittent hemodialysis is associated with adverse end organ effects in the heart or with cerebral oxygenation (regional O2 saturation [rSO2]). We assessed intradialytic cardiovascular function and rSO2, using noninvasive echocardiography to determine myocardial strain and continuous noninvasive nearinfrared spectroscopy for rSO2. We measured changes in blood volume and central venous oxygen saturation (mCVO2) were pre-, mid-, and post-hemodialysis. Results The study included 15 patients (median age, 12 years; median hemodialysis vintage 13.2 [9, 24] months were included. Patients were asymptomatic. The rSO2 did not change during hemodialysis, whereas mCVO2 decreased significantly, from 73% to 64.8 %. Global longitudinal strain of the myocardium worsened significantly by mid-hemodialysis and persisted post-hemodialysis. The ejection fraction remained normal. Lower systolic blood pressure and faster blood volume change were associated with worsening myocardial strain; only blood volume change was significant in multivariate analysis (β coefficient, -0.3; 95% confidence interval [95% CI], −0.38 to −0.21; P=0.0001). Blood volume change was also associated with a significant decrease in mCVO2 (β coefficient 0.42; 95% CI, 0.07 to 0.76; P=0.001). Access, age, hemodialysis vintage, and ultrafiltration volume were not associated with worsening strain. Conclusion s Unchanged rSO2 suggested that cerebral oxygenation was maintained during hemodialysis. However, despite maintained ejection fraction, intradialytic myocardial strain worsened in pediatric hemodialysis and was associated with blood volume change. The effect of hemodialysis on individual organ perfusion in pediatric versus adult patients receiving hemodialysis might differ.

Overhydration is reported to be the main cause of hypertension (HTN) as well as to have no association with HTN in hemodialysis (HD) population. This is the first report of the relationship between interdialytic weight gain (IDWG) and pre-HD blood pressure (BP) in pediatric patients in relation to residual urine output (RUO). We studied 170 HD sessions and interdialytic periods performed during a 12-week period in 5 patients [age 4–17 years, weight 20.8–66 kg, 3 anuric (102 HD sessions), and 2 nonanuric (68 HD sessions)]. BP is presented as systolic BP index (SBPI) and diastolic BP index (DBPI), calculated as systolic or diastolic BP/95th percentile for age, height, and gender. IDWG did not differ (P>0.05) between anuric and nonanuric pts. There was a positive but not significant correlation between IDWG and both pre-HD SBPI (r=0.833,P=0.080) and pre-HD DBPI (r=0.841,P=0.074). Pre-HD SBPI (1.01±0.12versus1.13±0.18) and DBPI (0.92±0.16versus1.01±0.24) were higher in nonanuric patents (P<0.001andP<0.01, resp.). Pre-HD HTN may not be solely related to IDWG and therapies beyond fluid removal may be needed. Individualized approach to HTN management is necessary in pediatric dialysis population.

<b><i>Aims:</i></b> Traditional methods that use clinical parameters to determine dry weight in hemodialysis patients are inaccurate. This study aimed to compare clinical assessment of fluid status to sonographic parameters of fluid status in pediatric patients undergoing chronic hemodialysis. <b><i>Methods:</i></b> In a prospective observational study, pediatric patients maintained on chronic hemodialysis (ages 2.3–20 years) were evaluated clinically and sonographically before and after dialysis at 6 consecutive sessions. Sonographic parameters examined were number of lung B-lines as a measure of extravascular volume and inferior vena cava (IVC)/aorta ratio as a measure of intravascular volume. Clinical assessment of fluid status was compared to sonographic assessment. <b><i>Results:</i></b> Twelve patients were evaluated during 72 dialysis sessions. Sonographic parameters were significantly lower post-dialysis than pre-dialysis (B-lines number 4.5 ± 5 vs. 7.69 ± 7.46, <i>p</i> &#x3c; 0.0001; IVC/aorta ratio 0.9 ± 0.2 vs. 1.1 ± 0.2, <i>p</i> &#x3c; 0.0001, respectively). Ultrafiltration volume correlated with change in B-lines number during dialysis (<i>r</i> = 0.39, <i>p</i> &#x3c; 0.01). Percent of blood volume drop correlated with post-dialysis IVC/aorta ratio (<i>r</i> = 0.48, <i>p</i> &#x3c; 0.001). A higher percent of symptomatic episodes occurred with post-dialysis IVC/aorta ratio &#x3c;0.8 versus ≥0.8 (39.1 vs. 15.2%, <i>p</i> = 0.036). Four patients were hypertensive, a clinical parameter implying fluid overload, in only one sonographic evaluation indicated fluid overload. Eight patients were clinically determined to be euvolemic, in three of them sonographic evaluation discovered covert fluids. <b><i>Conclusion:</i></b> Bedside ultrasound is a single modality that can be used to assess both extravascular and intravascular fluid status. It may contribute to clinical decisions differentiating fluid-related versus fluid-unrelated hypertension and identifying patients with covert fluids.
