Association between Blood Potassium Level and Recovery of Postoperative Gastrointestinal Motility during Continuous Renal Replacement Therapy in Patient Undergoing Open Abdominal Surgery

Figure 2

Kaplan–Meier analysis between blood potassium level and postoperative gastrointestinal motility. It indicated that, compared with the patients with insufficient blood potassium levels (plasma potassium concentration < 4.00 mmol/L), those with sufficient levels (plasma potassium concentration ≥4.00 mmol/L) had higher rates of 4-day postoperative recovery of gastrointestinal motility (p<0.001).
