Effects of Chinese acupuncture on nausea and vomiting after cholecystectomy: A retrospective study

Figure 3 Post-operative nausea and vomiting incidence by surgical approach. Acupuncture treatment significantly reduced post-operative nausea and vomiting incidence rates in both laparoscopic (26.7% vs 45.6%, P < 0.01) and open surgery groups (33.3% vs 53.3%, P < 0.05) compared to control groups. Although open surgery patients demonstrated higher baseline post-operative nausea and vomiting risk than laparoscopic patients, acupuncture showed consistent preventive efficacy across both surgical approaches, with similar numbers needed to treat (needed to treat 5.0-5.3). ^aP < 0.05.
