Participants were assigned by enrollment time to a press-needle group (PC6, LI4, ST36, applied 30 min pre-anesthesia and retained for 48 h) or a control group (standard care). Primary outcomes were nausea\/vomiting rates and severity at four intervals (0\u20136 to 24\u201348 h post-op). Secondary outcomes were rescue antiemetic use and vital signs at baseline, immediately post-procedure, 6 and 24 h.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Generalized estimating equation analysis demonstrated that both groups experienced a significant reduction in the rates of nausea and vomiting over time (both\n P<\/jats:italic>\n &lt; 0.001). The press-needle group had significantly lower rates of nausea (OR = 0.417, 95% CI: 0.193\u20130.900,\n P<\/jats:italic>\n = 0.026) and vomiting (OR = 0.355, 95% CI: 0.137\u20130.919,\n P<\/jats:italic>\n = 0.033) than the control group. Furthermore, the press-needle group had significantly fewer patients experiencing mild, moderate, or severe nausea and vomiting (\n P<\/jats:italic>\n &lt; 0.001) than the control group. The overall use of rescue antiemetics was also significantly lower in the press-needle group [7 cases (6.48%) vs. 22 cases (20.37%),\n P<\/jats:italic>\n = 0.004] than that in the control group. With respect to vital signs, systolic and diastolic blood pressures were significantly higher in the press-needle group immediately after the procedure (\n P<\/jats:italic>\n &lt; 0.001), but no significant differences were observed at 6 or 24 h postoperatively (\n P<\/jats:italic>\n &gt; 0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Press-needle therapy effectively reduces the rates and severity of PONV following bronchoscopy under general anesthesia, decreases the need for rescue antiemetic medication, and demonstrates a minimal impact on vital signs, suggesting its potential as a valuable adjunctive clinical intervention.<\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fmed.2026.1813642","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T05:40:18Z","timestamp":1780638018000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["The effect of press-needle therapy on postoperative nausea and vomiting in patients undergoing bronchoscopy under general anesthesia in China: a quasi-experimental study"],"prefix":"10.3389","volume":"13","author":[{"given":"Kunying","family":"Li","sequence":"first","affiliation":[{"name":"Henan Provincial Chest Hospital, Respiratory Endoscopy Center, Zhengzhou University","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taomei","family":"Lian","sequence":"additional","affiliation":[{"name":"Departments of Tuberculosis and Integrated Traditional Chinese and Western Medicine, Henan Provincial Chest Hospital, Zhengzhou University","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaozhen","family":"Lou","sequence":"additional","affiliation":[{"name":"Hainan Xubairui Biotechnology Co., Ltd.","place":["Haikou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Tuberculosis Internal Medicine, Henan Provincial Chest Hospital, Zhengzhou University","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangzhao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Henan Provincial Chest Hospital, Zhengzhou University","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zaigui","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Medicine Rehabilitation, Henan Provincial Chest Hospital","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingcai","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Research, Henan Provincial Chest Hospital, Zhengzhou University","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qinqin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Clinical Laboratory, Zhengzhou Daqiao Hospital","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,6,5]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"313","DOI":"10.1136\/postgradmedj-2021-141359","article-title":"Prospective cohort study of topical versus general anaesthesia for flexible bronchoscopy.","volume":"99","author":"Feng","year":"2023","journal-title":"Postgrad Med J."},{"key":"B2","article-title":"Postoperative nausea.
