Effect of Electroacupuncture on SAP With MODS

1. Title: Effect of Electroacupuncture on Severe Acute Pancreatitis with Multiple Organ Disfunction Syndrome patients: A Randomized Clinical Trial 2. Research center: single center 3. Design of the research: A randomized, double-blind and parallel controlled study 4. Object of the research: The patients over 18 years that met the criteria of SAP and with more than 2 organs failure. 5. Sample size of the research: A total of 220patients,110 cases in each group 6. Interventions: The acupuncture points for electroacupuncture are Zusanli(ST36), Xiajuxu(ST39), Hegu(LI4), Neiguan(PC6) points . Participants in the treatment group underwent 30 minutes acupuncture (0.30mm×70mm) at above points once a day for seven days. After"Deqi",electroacupuncture stimulation apparatus (HANS G6805-2, Huayi Co, Shanghai, China) is connected and maintained the end of treatment. Participants in the control group received shallow needling (0.30mm×25mm) at nonacupoints (located 1 inch beside acupoints). Specifically, the depth of needle insertion into nonacupoints is 3-5mm and avoided manual stimulation and no "Deqi" without actual current output. 7. Aim of the research: To investigate the effect of electroacupuncture on Severe Acute Pancreatitis with Multiple Organ Disfunction Syndrome. 8. Outcome #Primary outcomes: All-cause 28-day mortality. Secondary outcomes: Duration of organ failure; The incidence of pancreatic necrotic tissue infection; Time for enteral nutrition to reach the standard (30kcal/kg); Mechanical ventilation time; Length of hospital stay 9. The estimated duration of the study#2 years.
