<![CDATA[Background: Postoperative Nausea and Vomiting (PONV) is a common complication following surgery, particularly in patients undergoing spinal anesthesia. Cardamom aromatherapy is a non-pharmacological intervention that is believed to have antiemetic and relaxation effects. Objective: To determine the effect of cardamom aromatherapy on Postoperative Nausea and Vomiting in patients undergoing spinal anesthesia. Methods: This study employed a quasi-experimental design with a two-group pretest–posttest design involving 60 respondents selected using purposive sampling (30 in the experimental group and 30 in the control group). The experimental group received cardamom aromatherapy, while the control group received standard care. PONV was assessed using the Rhodes Index of Nausea, Vomiting, and Retching (RINVR). Data were analyzed using the Wilcoxon and Mann–Whitney tests. Results: The mean PONV score in the experimental group decreased from 2.53 to 1.93 (p<0.001), while the control group decreased from 2.30 to 2.00 (p=0.003). The between-group comparison showed no statistically significant difference (p=0.305). Conclusion: Cardamom aromatherapy was not more effective than standard care in reducing PONV among patients undergoing spinal anesthesia. Future studies should evaluate the concentration, duration, and timing of aromatherapy administration and control factors influencing PONV to obtain more optimal outcomes. ]]>
