Background: Females undergoing laparoscopic gynaecological surgeries have a high incidence of postoperative nausea and vomiting. Apart from the established risk factors, hormonal, psychological, genetic and ethnic factors may also contribute to postoperative nausea and vomiting. This study aimed to evaluate the relationship between preoperative anxiety and serum oestrogen level with postoperative nausea and vomiting in patients undergoing diagnostic laparoscopy – hysteroscopy for infertility. Methods: In total, 100 female patients, between the ages of 20-40 years, undergoing diagnostic laparoscopy – hysteroscopy for infertility were recruited for this study. Preoperative anxiety level was assessed using Depression, Anxiety and Stress Scale-21 (DASS-21) Questionnaire. Serum oestrogen samples were taken before anaesthesia. Postoperative nausea and vomiting grading was rated with 0–3 Likert-type scale. An association of anxiety and oestrogen levels to postoperative nausea and vomiting was done. Results: The analysis between median DASS 21 scores to postoperative nausea and vomiting grading showed no association between DASS 21 scores and postoperative nausea and vomiting grades. Comparing the mean oestrogen levels in patients among each grade of postoperative nausea and vomiting showed no significant difference in the mean oestrogen levels. Conclusion: Our study did not find evidence of a significant association between serum oestrogen levels, preoperative anxiety, and postoperative nausea and vomiting.
