What to Do in a Chinese IVF Emergency - Reproductive Center Emergency Identification and Medical Guide

Opening: Real medical visit experience

⚕️ Last week on night shift, I received a patient on the 4th day after egg retrieval. She had undergone IVF in another city and returned home, where she developed bloating, nausea, and decreased urine output. She thought resting for two days would help. By the time she came to the hospital, she could not lie flat and was short of breath. Examination revealed a large amount of abdominal fluid, blood tests indicated hemoconcentration, and hCG was positive. She was diagnosed with moderate Ovarian Hyperstimulation Syndrome (OHSS) combined with early pregnancy, requiring hospitalization. This case is very representative of reproductive center emergencies—many patients fail to recognize the "abnormal signals" during IVF treatment, leading to delayed medical attention.

1. Emergency Judgment Criteria

1. When to Go to the Emergency Room: Four Core Judgment Criteria

During IVF treatment, if the following four types of symptoms occur, seek medical attention promptly. Do not wait because you "think it's nothing" or "don't want the trouble."

Symptom Category	Specific Manifestations	Management Advice
Abdominal Pain	Mild: dull ache, tolerable, no accompanying symptoms Moderate: persistent worsening, affecting sleep and eating Severe: intense abdominal pain, accompanied by nausea, cold sweats, dizziness	Mild → Observe; Moderate → Seek medical advice; Severe → Go to ER immediately
Bleeding	Vaginal bleeding after egg retrieval exceeding menstrual flow or continuous bleeding Large amount of bright red bleeding after embryo transfer, with abdominal pain Vaginal bleeding with lower abdominal pain after confirmed pregnancy	If any one of these occurs, go to the ER
Bloating	Progressive worsening of bloating, decreased urine output (less than 1000ml/day) Accompanied by difficulty breathing, inability to lie flat Weight gain of more than 3 kg within 3-5 days	Moderate or severe bloating suggests ER evaluation
Fever	Body temperature over 38.5°C, with abdominal pain or abnormal vaginal discharge Fever after egg retrieval or embryo transfer, infection must be ruled out	Go to ER immediately

2. Chinese IVF Emergency Medical Procedure: Which Department, What to Bring, How to Handle

2.1 Choosing the Department

• Weekdays during the day: Priority to return to your original reproductive center. The doctors there know your treatment best.
• Nights or holidays: Go to the Gynecology Emergency of a tertiary hospital. Most tertiary hospitals have 24-hour gynecology services.
• No gynecology emergency: Go to the Emergency Department of a general hospital, and the emergency doctor will contact gynecology for consultation.

It is not recommended to go to Gastroenterology, General Surgery, or community hospitals, as these departments are not familiar with IVF-related complications and may misdiagnose or delay treatment.

2.2 Materials to Bring for Your Visit

2.3 Emergency Treatment Process

1. Triage: The nurse measures vital signs (blood pressure, heart rate, temperature, respiration) and prioritizes based on severity.
2. Doctor Consultation: Detailed inquiry about the treatment stage, symptom onset time, medication history, and past medical history.
3. Examination and Evaluation: Blood count, coagulation function, hCG, pelvic ultrasound. Repeat liver and kidney function, electrolytes if necessary.
4. Diagnosis and Management: Treatment based on the cause (fluid resuscitation, hemostasis, paracentesis drainage, surgery, etc.).
5. Observation or Hospitalization: Mild cases observed in the outpatient clinic for 2-4 hours; moderate to severe cases admitted.

Emergency test results are usually available within 1-2 hours. Management for mild cases can be completed in 2-4 hours. Those requiring hospitalization are admitted on the same day.

3. Analysis of Emergency Scenarios at Different Stages

3. Analysis of Emergency Scenarios at Different Stages

Treatment Stage	Main Risk	Time of Occurrence	Key Signals	Management
Ovarian Stimulation	OHSS	3-7 days after hCG injection	Bloating, decreased urine output, rapid weight gain, difficulty breathing	Mild: high-protein diet + monitoring; Moderate to severe: hospitalization for fluid resuscitation + paracentesis drainage
Post Egg Retrieval	Intra-abdominal bleeding, pelvic infection	24-72 hours post-procedure	Progressive worsening abdominal pain, dizziness, pallor, increased heart rate	Minor bleeding → conservative treatment; Major bleeding → hospitalization/surgical hemostasis
2-3 Weeks Post Transfer	Ectopic pregnancy, ovarian torsion	14-21 days post transfer	Unilateral lower abdominal pain, brown/bright red vaginal bleeding, suboptimal hCG rise	Ectopic pregnancy → medication or surgery; Ovarian torsion → emergency surgery
After Confirmed Pregnancy (First Trimester)	Early miscarriage, worsening OHSS	6-12 weeks of pregnancy	Increased vaginal bleeding, worsening abdominal pain, declining hCG	Treatment to maintain or terminate pregnancy based on cause

4. The Most Easily Overlooked Details

4. The Five Most Easily Overlooked Details

• Decreased urine output is a core indicator: Many patients focus only on abdominal pain and bleeding, ignoring urine output. Daily urine output less than 1000ml or no urine for 6 hours indicates OHSS has affected kidney function and requires timely intervention.
• The location and nature of abdominal pain are very important: Unilateral severe abdominal pain with a sensation of rectal pressure is a typical sign of intra-abdominal bleeding, easily mistaken for gastroenteritis or constipation.
• Rapid weight gain: Gaining more than 3 kg within 3 days indicates fluid and sodium retention in the body, a clear sign of worsening OHSS.
• The hCG injection time must be told to the doctor: The timing of the hCG injection before egg retrieval is directly related to OHSS risk. Be sure to state the injection date and dose during the visit.
• Past medical history must not be concealed: Polycystic ovary syndrome, previous OHSS history, drug allergies—this information is crucial in emergency evaluation.

5. Common Patient Mistakes in Management

5. Most Common Patient Mistakes in Management

• Self-medicating with painkillers: Ibuprofen, acetaminophen, etc., can mask symptoms and delay diagnosis. Do not take any painkillers before going to the ER.
• Applying heat or cold packs to the abdomen: If there is intra-abdominal bleeding, heat packs can dilate blood vessels and worsen bleeding; cold packs also hinder the doctor's assessment of signs.
• Drinking large amounts of water: OHSS patients need to restrict fluid intake. Blindly drinking water can worsen bloating and ascites.
• Waiting until morning to seek medical attention: If severe symptoms occur at night, do not wait. Nighttime emergency departments are equally equipped for examination and management.
• Going to the wrong department: Going to Gastroenterology, General Internal Medicine, or community hospitals, where doctors are unfamiliar with IVF complications, can lead to misdiagnosis or advice to "just observe."
• Not bringing medical records: Without medication and surgical records, doctors cannot accurately assess the condition and must spend time re-learning the treatment history.

6. How Doctors Assess Emergency Severity

6. How Doctors Assess Emergency Severity

As emergency doctors, we quickly assess the patient's condition through the following steps:

1. Vital signs: Blood pressure, heart rate, respiration, temperature. Low blood pressure + increased heart rate may indicate internal bleeding or shock.
2. Symptom characteristics: Location, nature, duration, and radiation of abdominal pain; amount, color, and presence of clots in bleeding; degree of bloating and its impact on breathing.
3. Auxiliary examinations: Blood count (decreased hemoglobin → bleeding), coagulation function (assess bleeding risk), hCG (determine pregnancy status), ultrasound (pelvic fluid, gestational sac location, ovarian size).
4. Risk assessment: Based on the above results, determine whether outpatient observation or hospitalization is needed. Moderate to severe OHSS, active intra-abdominal bleeding, and ruptured ectopic pregnancy all require hospitalization.

8. Special Situation Management

8. Key Points for Special Situation Management

• Ovarian torsion: After ovarian stimulation, the ovaries enlarge and are prone to torsion. It presents as sudden, severe unilateral abdominal pain with nausea and vomiting. Emergency surgical detorsion or fixation is needed.
• Pelvic infection: Fever, abdominal pain, and increased or foul-smelling vaginal discharge after egg retrieval or transfer. Requires antibiotic treatment; severe cases need hospitalization.
• Ruptured ectopic pregnancy: Typical symptoms are severe abdominal pain + intra-abdominal bleeding + shock. Emergency surgery is required without any delay.
• Drug allergy: Skin rash, laryngeal edema, difficulty breathing caused by ovulation induction or luteal support drugs. Stop the medication immediately and seek emergency treatment.
