Moxibustion for Chemotherapy-Induced Nausea and Vomiting: A Systematic Review and Meta-Analysis

Abstract EN

Nausea and vomiting are distressing symptoms for patients receiving chemotherapy.

Moxibustion, which involves the use of burning moxa to generate heat and stimulate acupoints, has been reported to potentially ameliorate chemotherapy-induced side effects, particularly nausea and vomiting.

This systematic review evaluated current evidence on the effectiveness of moxibustion against chemotherapy-induced nausea and vomiting (CINV).

We searched eight online databases and two trial registries for relevant trials.

The random-effects model was used to conduct a meta-analysis.

Furthermore, the risk ratio (RR) and mean difference (MD) were used to explain dichotomous and continuous outcomes, respectively; the outcomes were within 95% confidence intervals (CIs).

The results revealed that moxibustion might more favorably relieve the severity and frequency of CINV, compared with no treatment (RR: 2.04, 95% CI: 1.42–2.93); moxibustion might have stronger effects than antiemetic drugs (RR: 1.87, 95% CI: 1.27–2.76).

There is no robust result that moxibustion could enhance the effects of antiemetic drugs administered as a complementary treatment.

Actual moxibustion (8.10±10.98) may have more favorable effects than placebo moxibustion (46.67±23.32).

However, the evidence obtained is not sufficient because of the lack of strict clinical trials.
