Rhubarb vs. glycerin enema for treatment of critically ill patients with intra-abdominal hypertension

Rhubarb has been used as an evacuant for thousands of years. However, recent research has indicated that rhubarb inhibits inflammation and protects organ function. In the current study, the use of rhubarb was investigated in patients with intra-abdominal hypertension (IAH). Specifically, its dual role in attenuating lung and bowel injury by catharsis and inhibiting inflammation was evaluated. Patients in the glycerin group (n=56) received 110 ml of glycerin enema by coloclysis once daily for 7 to 9 days. Patients in the rhubarb group (n=56) were treated with a mixture of 0.3 g/kg body weight rhubarb powder in 100 ml warm water. The Acute Physiology and Chronic Health Evaluation II (APACHE II), Sepsis-Related Organ Failure Assessment (SOFA), intra-abdominal pressure, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 levels were recorded. The duration of mechanical ventilation (MV), respiratory parameters, first day of enteral nutrition (EN), intensive care unit (ICU) hospital stay and 30-day mortality were also recorded. The APACHE II scores were significantly lower in the rhubarb group compared with the glycerin group from day 3 to 9 (P
