covering the period from database inception to June 6

2024. Randomized controlled trials (RCTs) on TEAS for the prevention and treatment of PONV after laparoscopic surgery were included. Two researchers independently completed literature screening

data extraction

and quality assessment. Meta-analysis of the extracted data was performed using RevMan5.3 and StataMP14 software.

Results

2

A total of 33 studies were included

involving 6 271 laparoscopic surgery patients

with 3 372 in the TEAS group and 2 899 in the control group. The Meta-analysis results showed that

compared with the control group

the incidence of PONV within 24 hours after laparoscopic surgery was lower in the TEAS group [

Conclusion

2

TEAS could effectively reduce the incidence of PONV

the requirement for postoperative rescue antiemetics

and the severity of PONV in patients undergoing laparoscopic surgery

thereby promoting patient recovery.
