Transcutaneous Electrical Acupoint Stimulation(TEAS) for Hepatic and Renal Dysfunction After Pneumoperitoneum


The purpose of this study is to compare the effect of TEAS pretreatment and treatment on hepatic and renal dysfunction induced by pneumoperitoneum in patients undergoing laparoscopic surgeries.

Full Title of Study: “Effect of Transcutaneous Electrical Acupoint Stimulation(TEAS) on the Hepatic and Renal Function Impaired by Pneumoperitoneum: a Prospective, Randomized Controlled Trial”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Single (Outcomes Assessor)
  • Study Primary Completion Date: December 2015

Detailed Description

Patients were randomly assigned to three groups, control group and two intervention groups, receiving TEAS before and after general anesthesia induction respectively. TEAS was given through electrodes attached to acupoints. The time for TEAS was 30min. Venous blood samples were collected before and 20min after pneumoperitoneum. Hepatic and renal function index including AST, ALT, ALP, BUN, Cr were measured.


  • Other: TEAS pretreatment
    • Electric stimulation was given through electrode attached to specific acupoints for 30mins before anesthesia induction
  • Other: TEAS treatment
    • Transcutaneous Electrical Acupoint Stimulation was given to the patient at the same time of the start of anesthesia induction for 30mins

Arms, Groups and Cohorts

  • No Intervention: Control
    • Patients were given no TEAS
  • Experimental: TEAS Pretreatment
    • Patients were given 30min of TEAS before pneumoperitoneum
  • Experimental: TEAS Treatment
    • Patients were given 30min of TEAS during pneumoperitoneum

Clinical Trial Outcome Measures

Primary Measures

  • Incidence of renal or hepatic dysfunction
