Background The transition of dialysis modalities from continuous renal replacement therapy (CRRT) to intermittent hemodialysis (iHD) is frequently conducted during the recovery phase of critically ill patients with acute kidney injury. Herein, we addressed the occurrence of intradialytic hypotension (IDH) after this transition, and its association with the mortality risk.
Methods A total of 541 patients with acute kidney injury who attempted to transition from CRRT to iHD at Seoul National University Hospital, Korea from 2010 to 2020 were retrospectively collected. IDH was defined as a discontinuation of dialysis because of hemodynamic instability plus a nadir systolic blood pressure <90 mm Hg or a decrease in systolic blood pressure ≥30 mm Hg during the first session of iHD. Odds ratios (ORs) of outcomes, such as in-hospital mortality and weaning from RRT, were measured using a logistic regression model after adjusting for multiple variables.
Results IDH occurred in 197 patients (36%), and their mortality rate (44%) was higher than that of those without IDH (19%; OR, 2.64; 95% confidence interval [CI], 1.70–4.08). For patients exhibiting IDH, the iHD sessions delayed successful weaning from RRT (OR, 0.62; 95% CI, 0.43–0.90) compared with sessions on those without IDH. Factors such as low blood pressure, high pulse rate, low urine output, use of mechanical ventilations and vasopressors, and hypoalbuminemia were associated with IDH risk.
Conclusions IDH occurrence following the transition from CRRT to iHD is associated with high mortality and delayed weaning from RRT.

Background Coronary artery stenosis increases hospital mortality and leads to poor neurological recovery in cardiac arrest (CA) patients. However, electrocardiography (ECG) cannot fully predict the presence of coronary artery stenosis in CA patients. Hence, we aimed to determine whether regional wall motion abnormality (RWMA), as observed by two-dimensional echocardiography (2DE), predicted patient survival outcomes with greater accuracy than did ST segment elevation (STE) on ECG in CA patients who underwent coronary angiography (CAG) after return of spontaneous circulation.
Methods This was a retrospective observational study of adult patients with CA of presumed cardiac etiology who underwent CAG at a single tertiary care hospital. We investigated whether RWMA observed on 2DE predicted patient outcomes more accurately than did STE observed on ECG. The primary outcome was incidence of hospital mortality. The secondary outcomes were Glasgow-Pittsburgh Cerebral Performance Category scores measured 6 months after discharge and significant coronary artery stenosis on CAG.
Results Among the 145 patients, 36 (24.8%) experienced in-hospital death. In multivariable analysis of survival outcomes, only total arrest time (P=0.011) and STE (P=0.035) were significant. The odds ratio (OR) and 95% confidence interval (CI), which were obtained by adjusting the total arrest time for survival outcomes, were significant only for STE (OR, 0.40; 95% CI, 0.17–0.94). The presence of RWMA was not a significant factor.
Conclusions While STE predicted survival outcomes in adult CA patients, RWMA did not. The decision to perform CAG after CA should include ECG under existing guidelines. The use of RWMA has limited benefits in treatment of this population.
