Objective:

To evaluate the efficacy of press-needle therapy in preventing postoperative nausea and vomiting (PONV) in patients undergoing bronchoscopy under general anesthesia at Henan Provincial Chest Hospital in China.

Key Findings:

• The press-needle group had significantly lower rates of nausea (OR = 0.417, 95% CI: 0.193–0.900, P = 0.026) and vomiting (OR = 0.355, 95% CI: 0.137–0.919, P = 0.033) compared to the control group.
• Fewer patients in the press-needle group experienced mild, moderate, or severe nausea and vomiting (P < 0.001).
• Rescue antiemetic use was significantly lower in the press-needle group (6.48%) compared to the control group (20.37%, P = 0.004).
• Systolic and diastolic blood pressures were significantly higher in the press-needle group immediately post-procedure (P < 0.001).

Interpretation:

Press-needle therapy effectively reduces the rates and severity of PONV following bronchoscopy under general anesthesia, decreases the need for rescue antiemetic medication, and suggests a potential for improved patient outcomes.

Limitations:

• The study was conducted at a single center, which may limit generalizability.
• The quasi-experimental design may introduce selection bias.
• The sample size, while adequate, may not fully represent the broader population.

Conclusion:

Press-needle therapy is a valuable adjunctive clinical intervention for reducing PONV in patients undergoing bronchoscopy under general anesthesia, with implications for improving patient care.
