Anesthesia Recovery Period, Estrogens, In Vitro Fertilization, Postoperative Recovery
Conditions
Brief summary
This prospective observational study aims to evaluate the relationship between supraphysiologic serum estrogen levels and postoperative recovery quality in patients undergoing IVF procedures under general anesthesia. Estrogen is known to play a role in pain modulation and emotional responses, both of which influence postoperative recovery. The primary outcome is the quality of recovery score (QoR-15), and secondary outcomes include postoperative pain, nausea and vomiting, and discharge time. A total of 100 adult female patients will be included. The study seeks to provide better insight into how elevated estrogen levels may impact patient outcomes after anesthesia.
Detailed description
Postoperative recovery is a multidimensional and complex process influenced by pain, nausea and vomiting, emotional and functional factors. IVF (In Vitro Fertilization) treatments involve controlled ovarian hyperstimulation, which causes supraphysiologic increases in serum estrogen levels. Elevated estrogen is thought to affect pain modulation and inflammatory pathways and has been associated with increased symptoms such as nausea and mood fluctuations. This prospective observational study aims to investigate the relationship between serum estrogen concentration and the quality of recovery in patients undergoing IVF-related transvaginal oocyte retrieval under general anesthesia. A total of 100 ASA I-II adult female patients between the ages of 18 and 45 will be enrolled. Patients will be grouped based on their estradiol (E2) levels measured as part of the routine IVF procedure. E2 levels above 350 pg/ml will be defined as supraphysiologic. The primary outcome is the postoperative recovery quality assessed using the QoR-15 questionnaire at 24 and 72 hours postoperatively. Secondary outcomes include postoperative pain intensity (measured by the Numerical Rating Scale), nausea and vomiting (assessed by Verbal Descriptive Scale), and time to discharge (evaluated using the Modified Aldrete Score). Preoperative anxiety and depression will be assessed using the Hospital Anxiety and Depression Scale (HADS). This study aims to contribute to improved anesthetic and perioperative management of IVF patients with elevated estrogen levels.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative Recovery Quality (QoR-15 Score) | 24 hours and 72 hours after surgery | Assessed using the Quality of Recovery-15 (QoR-15) questionnaire at 24 and 72 hours postoperatively. The score ranges from 0 to 150, with higher scores indicating better recovery. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative Pain Intensity (NRS Score) | 24 and 72 hours after surgery | Assessed using the Numerical Rating Scale (NRS) where 0 indicates no pain and 10 indicates worst imaginable pain. |
| Postoperative Nausea and Vomiting (VDS Score) | 24 and 72 hours after surgery | Evaluated using the Verbal Descriptive Scale (VDS); scale ranges from 0 (none) to 4 (severe nausea and vomiting). |
