Research: CHENGWEI and COLLEAGUES

Abstract
CHENGWEI and COLLEAGUES, 1 Hubei University of Traditional Chinese Medicine; 2 Zhuji People's Hospital of Zhejiang Province, Zhuji, China; 3 Zhongnan Hospital of Wuhan University; 4 Hubei Provincial Hospital of Traditional Chinese Medicine; 5 Hubei Province Academy of Traditional Chinese Medicine, Wuhan conducted a network meta-analysis aimed to evaluate the effectiveness of different acupuncture therapies used for preventing Postoperative nausea (POV) and vomiting (PONV) in abdominal operations.
Background
Postoperative nausea and vomiting (PONV) is a common complication after surgery. However, drugs cannot prevent it completely, and acupuncture therapy shows the potential in preventing PONV, yet the best choice hasn't been demonstrated.
Methodology
Authors searched articles from PubMed/Medline, Cochrane library, Web of Science, EBSCO and Ovid/Embase, and established database from setup time to June 2019. Quality evaluation of included studies was performed with Cochrane risk-of-bias tool (ROB 2.0). Pairwise and network meta-analysis were conducted by RevMan and Addis respectively.
Results
Twenty studies with 2862 patients were included in this research. Pairwise meta-analysis shows that compared with placebo, transcutaneous electric nerve stimulation had lower risk of postoperative nausea (PON) (odds ratio (OR) = 0.42, 95% confidence interval (CI): 0.30-0.60), postoperative vomiting (POV) (OR = 0.53, 95%CI: 0.36-0.78), PONVs (OR = 0.46, 95%CI: 0.31-0.68), and postoperative rescue (POR) (OR = 0.61, 95%CI: 0.41-0.90), Capsicum had lower risk of PON (OR = 0.16, 95%CI: 0.09-0.28), PONVs (OR = 0.23, 95%CI: 0.12-0.45), Acupressure had lower risk of POV (OR = 0.42, 95%CI: 0.25-0.70), POR (OR = 0.42, 95%CI: 0.27-0.64). In network meta-analysis, compared with usual care, the probability rank suggested that Acupoint Injection showed lowest risk of PON (OR = 0.02, 95%CI: 0.00-0.11), POV (OR = 0.06, 95%CI: 0.01-0.49), Usual care for PONVs (OR = 0.31, 95%CI: 0.13-0.75), and Capsicum for POR (OR = 0.39, 95%CI: 0.07-2.33). Further study should be carried out to verify this result.
Conclusion
Both pairwise and network meta-analysis showed acupuncture therapy was superior to placebo and usual care. Different acupuncture therapy regimens may have advantages in different aspects. And compared with POV, PON seems easier to control. Research results may provide guidance for the prevention of PONV. Systematic review registration: PROSPERO CRD42019147556.

Comment
The above pairwise and network meta-analysis research from China demonstrated that acupuncture was superior to placebo and usual care used for preventing Postoperative vomiting (POV) and Postoperative nausea and vomiting (PONV) in abdominal operations.
