The hemodynamic tolerability and feasibility of sustained low efficiency dialysis in the management of critically ill patients with acute kidney injury

Table 2 Hemodynamic tolerability of CRRT vs SLED

	CRRT (n = 86)	SLED (n = 39)	p-value
MAP prior to treatment session (mmHg)	74.1 ± 10.0	76.4 ± 13.1	0.34
Vasopressor requirement prior to RRT session (%)	62 (72.1)	19 (48.7)	0.01
Volume ultrafiltered per session (mL)	1823 ± 1464	1915 ± 1302	0.74
Sessions associated with > 20% reduction in MAP (%)	16 (18.6)	15 (38.5)	0.02
Sessions with vasopressor escalation (%)^a	34 (39.5)	10 (25.6)	0.13
Unstable sessions^b (%)	43 (50.0)	22 (56.4)	0.51

Continuous variables are presented as mean ± SD. Categorical variables are presented as number of sessions (%).
SLED = sustained low efficiency dialysis
CRRT = continuous renal replacement therapy
MAP = mean arterial pressure
^aIncludes any increase in pressor dosage, as well as initiation of pressors
^bDefined as a treatment associated with a > 20% intra-treatment reduction in MAP or a treatment on which an escalation in pressor requirement occurred
