Egg retrieval is performed while under narcotic conscious sedation. The patient receives intravenous medication to help with discomfort (Fentanyl®) and relaxation (Midazolam (Versed®)) prior to the procedure. It is important to be aware that the College of Physicians & Surgeons of Alberta (CPSA) have decreed that intravenous Fentanyl® and Midazolam should only be given to patients with a Body Mass Index (BMI) of under 40 for safety reasons. You may calculate your BMI from the following formula: BMI = (weight in kilograms)/(height in metres)². The patient is awake but relaxed, drowsy and comfortable. Egg retrieval is accomplished by inserting the vaginal ultrasound probe (same probe as in the monitoring process) with a hollow bore aspiration needle attached into the vagina. The ovaries and follicles are visualized on ultrasound, and the needle is then passed through the wall of the vagina to access each ovary. The follicle contents (follicular fluid, cells and egg) are aspirated and drained into a test tube. The test tube is then collected by the embryology staff who examine the contents and collect the eggs under microscopic examination. The microscopic image of the eggs can be observed by the patient as the image is displayed on the TV monitor in the retrieval room. The technique of egg retrieval carries a small risk of damage to the internal organs, possible bleeding and infection.
