Summary
Transcutaneous electrical acupoint stimulation (TEAS) effectively reduces the incidence of postoperative delirium (POD) and pain in surgical patients. This technique shows promise as an assisted anesthesia method, improving patient outcomes and reducing anesthetic use.
Area of Science:
- Anesthesiology
- Gerontology
- Neurosurgery
Background:
- Postoperative delirium (POD) is a common complication in surgical patients, associated with increased morbidity and mortality.
- Current management strategies for POD are limited, highlighting the need for effective preventive interventions.
- Transcutaneous electrical acupoint stimulation (TEAS) is a non-invasive neuromodulation technique with potential therapeutic applications.
Purpose of the Study:
- To evaluate the efficacy and safety of TEAS in preventing POD among surgical patients.
- To assess the impact of TEAS on pain management, anesthetic consumption, and cognitive function post-surgery.
Main Methods:
- A meta-analysis of randomized controlled trials (RCTs) was conducted, including studies published up to December 30, 2022.
- Data from 12 RCTs involving 715 experimental and 717 control participants were synthesized.
- Outcome measures included POD incidence, Confusion Assessment Method (CAM) scores, Visual Analogue Scale (VAS) scores, and intraoperative anesthetic consumption.
Main Results:
- TEAS significantly reduced the incidence of POD within the first postoperative week.
- Subgroup analyses revealed lower CAM scores on postoperative day 3 and lower VAS scores on postoperative day 1 in the TEAS group.
- TEAS use was associated with significantly lower intraoperative consumption of propofol and remifentanil.
- No serious adverse events related to TEAS were reported.
Conclusions:
- TEAS demonstrates significant efficacy in preventing postoperative delirium and managing early postoperative pain in surgical patients.
- TEAS presents a promising, safe, and effective adjunctive anesthesia technique for improving surgical patient outcomes.
- Further research into TEAS as a standard perioperative intervention is warranted.
