About this study

Official title: Effects of Transcutaneous Electrical Acupoint Stimulation on the Postoperative Sleep Quality and Postoperative Cognition in Elderly Patients Undergoing Laparoscopic Abdominal Surgery

Elderly patients are often considered as a high-risk population for major abdominal surgery due to reduced functional reserve and increased comorbidities. Previous study reported that about 40 and 10% of elderly (60 yr and older) patients suffered from postoperative cognitive dysfunction (POCD) 7 days and 3 months, respectively, after noncardiac surgery. POCD is a central nervous system complication after anesthesia and an operation, whose risk factors include age, education level, the operation (time, type, and mode), anesthesia (methods, drugs, and time) and postoperative analgesia. In the study of Su X et al, elderly patients are also more prone to develop postoperative sleep disturbances after surgery with prolonged sleep latencies, fragmented sleep, decreased sleep efficiency and abnormally sleep stages. Increasing evidence showed that sleep and circadian rhythm disturbances after surgery could promote β-amyloid peptide (Aβ) accumulation by simultaneously upregulating Aβ synthesis and interfering with Aβ clearance. This insoluble Aβ aggregates to form brain extracellular senile plaques, which are one of the neuropathological hallmarks of numerous postoperative cognitive disorders such as Alzheimer's disease(AD), and can be measured by amyloid positron emission tomography (PET) imaging through injecting 18F-florbetapir, a novel imaging agent that binds with high affinity (Kd 3.1 nM+0.7) to β-amyloid peptide fibrils in brain amyloid plaques, to the patients.Transcutaneous electrical acupoint stimulation (TEAS) is a new acupuncture therapy developed by combining transcutaneous electrical nerve stimulation (TENS) in European and American countries and traditional Chinese acupuncture. TEAS treat disease through inputting a pulse current of different frequencies, intensities, and waveforms via electrode paste adhering to the skin. Previous studies proved that TEAS has been successfully applied in many different procedures through stimulating different acupoints such as reducing postoperative pain, postoperative nausea and vomiting (PONV), and improving postoperative sleep quality. However, whether TEAS could affect Aβ deposition by improving postoperative sleep quality and thus affect the development of long-term cognitive impairment is still unclear. The aim of our study is to conduct the TEAS intervention to elderly patients who received laparoscopic abdominal surgery, and then to examine its effect on postoperative sleep quality, postoperative cognition and complications. In this study, we utilized 18F-florbetapir imaging to assess the relationships between postoperative sleep disturbances and POCD and brain Aβ burden through measuring by PET imaging.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TEASDevice

    TEAS treatment was performed for 30 mins before anesthesia on bilateral side by an experienced acupuncturist at the Neiguan (PC6), HT7 (Shenmen), ST36 (Zusanli) and LI4 (Hegu) acupoints . And TEAS treatment for 30 mins was also performed on bilateral side by an experienced acupuncturist at the Neiguan (PC6), HT7 (Shenmen), ST36 (Zusanli) and LI4 (Hegu) acupoints at the end of surgery as well as on the each night before sleeping after surgery until discharged from the hospital

  • control groupOther

    Patients in the Control group received electrical stimulation at a non-acupoint which was located 2 cm interior to the bilateral Neiguan (PC6), HT7 (Shenmen), ST36 (Zusanli) and LI4 (Hegu) acupoints similar to patients in group TEAS

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sleep Quality Assessment

    use the Athens Insomnia Scale (AIS): the total AIS scores range from 0 to 24 points with ≤ 4 indicating no combined with insomnia at night; 4-6 indicating suspicious insomnia at night; ≥ 6 points indicating a diagnosis of insomnia at night

    Measured: on the first night before surgery (Preop 1)

  2. Sleep Quality Assessment

    use the Athens Insomnia Scale (AIS): the total AIS scores range from 0 to 24 points with ≤ 4 indicating no combined with insomnia at night; 4-6 indicating suspicious insomnia at night; ≥ 6 points indicating a diagnosis of insomnia at night

    Measured: the third night after surgery (POD 3).

  3. Sleep Quality Assessment

    use the Athens Insomnia Scale (AIS): the total AIS scores range from 0 to 24 points with ≤ 4 indicating no combined with insomnia at night; 4-6 indicating suspicious insomnia at night; ≥ 6 points indicating a diagnosis of insomnia at night

    Measured: the first week after surgery (POD 1W).

  4. Sleep Quality Assessment

    use the Athens Insomnia Scale (AIS): the total AIS scores range from 0 to 24 points with ≤ 4 indicating no combined with insomnia at night; 4-6 indicating suspicious insomnia at night; ≥ 6 points indicating a diagnosis of insomnia at night

    Measured: the sixth months after surgery (POD 6M).

  5. Cognitive Assessment

    MMSE is a 30-point questionnaire that is widely used to evaluate the severity of cognitive impairment in individuals with cognitive disorders. Score cutoffs for the MMSE are as follows: greater than or equal to 24 for normal cognition, between 19 and 23 for MCI, between 10 and 18 for moderate cognitive impairment, and less than or equal to 9 for severe cognitive impairment.
