 suction evacuation and curettage tailored for nursing students. This overview covers definitions, indications, procedure types, steps, nursing care, complications, and post-procedure considerations.

1. Overview and Definitions

Suction Evacuation and Curettage
This is a gynecological procedure used to empty the contents of the uterus. It is commonly performed for:

• Early pregnancy termination (abortion)
• Management of miscarriage (incomplete or missed abortion)
• Removal of retained products of conception
• Diagnosis and treatment of abnormal uterine bleeding

Note: The term “suction evacuation” typically refers to procedures using a vacuum (manual or electric) to aspirate uterine contents. “Curettage” involves scraping the uterine lining with a curette (a spoon-shaped instrument) to ensure complete removal or to obtain tissue for histopathological examination. In many cases, both techniques are used together.

2. Indications

The procedure is indicated in several clinical scenarios, including:

• Obstetric Applications:

  • Termination of early pregnancy (up to approximately 14–16 weeks)
  • Management of miscarriage (complete, incomplete, or missed abortion)
  • Evacuation of a molar pregnancy
  • Postpartum removal of retained placental tissue

• Gynecologic Applications:

  • Diagnostic evaluation of abnormal uterine bleeding or endometrial pathology
  • Treatment of conditions such as polyps or hyperplasia when sampling is required

3. Contraindications and Precautions

Before the procedure, it is essential to assess for contraindications, which include:

• Suspected or confirmed ectopic pregnancy
• Active pelvic infection (e.g., acute endometritis, salpingitis)
• Bleeding disorders or patients on anticoagulant therapy (unless corrected)
• Severe anemia or unstable medical conditions

Patients should also be evaluated for allergies (e.g., to anesthesia agents or antiseptics) and any contraindications to medications used in cervical preparation (such as misoprostol).

4. Types of Procedures

There are several approaches depending on gestational age and clinical setting:

A. Manual Vacuum Aspiration (MVA)

• Technique: Uses a hand-held syringe connected to a flexible cannula to generate suction.
• Setting: Typically performed in outpatient or office settings.
• Gestational Age: Often used in early pregnancy (approximately 5–10 weeks).

B. Electric Vacuum Aspiration (EVA)

• Technique: Uses an electric pump to produce continuous suction.
• Setting: Performed in hospitals or surgical centers.
• Gestational Age: Commonly used in first-trimester procedures (up to 14–16 weeks).

C. Sharp Curettage (Dilation and Curettage, D&C)

• Technique: Involves cervical dilation followed by scraping of the uterine lining with a curette.
• Application: May be combined with suction evacuation to ensure complete removal of tissue.

5. The Procedure: Step-by-Step

Pre-procedure Preparation

1. Patient Evaluation:
   • Obtain a thorough history, including menstrual and obstetric history.
   • Conduct a pelvic exam and confirm the diagnosis (often with ultrasound).
   • Identify any contraindications or allergies.
2. Informed Consent & Counseling:
   • Explain the purpose, benefits, risks, and alternatives to the procedure.
3. Cervical Preparation:
   • Agents such as misoprostol (a prostaglandin analog) or osmotic dilators (e.g., laminaria) may be used to soften and dilate the cervix.
4. Pre-medications:
   • Prophylactic antibiotics may be administered to reduce the risk of infection.
   • Pain management and sedation (local, moderate, or general anesthesia) are determined based on the procedure and patient needs.

Intra-procedure Steps

1. Positioning:
   • The patient is placed in the dorsal lithotomy position (on her back with legs in stirrups).
2. Aseptic Technique:
   • The perineal area is cleansed, and a sterile speculum is inserted to visualize the cervix.
3. Cervical Dilation:
   • Gradual dilation is achieved using a series of dilators (Hegar, Pratt, or manual rods) or pre-dilation agents.
4. Suction Evacuation:
   • For suction:
     • A cannula (manual or electric) is inserted through the dilated cervix.
     • Suction is applied to aspirate uterine contents gently.
   • For curettage:
     • A curette is used to scrape the uterine lining to ensure all tissue is removed or to collect a sample.
5. Ultrasound Guidance (Optional):
   • In some cases, ultrasound guidance is used to confirm complete evacuation and reduce the risk of complications.

Post-procedure Care

1. Observation:
   • The patient is monitored for 1–2 hours for vital signs, bleeding, and pain.
2. Medications:
   • Analgesics (e.g., ibuprofen, acetaminophen) are given for pain relief.
   • Continued antibiotics may be prescribed if indicated.
3. Discharge Instructions:
   • Information on signs of complications (excessive bleeding, fever, severe pain) is provided.
   • Recommendations on abstaining from inserting any vaginal objects (tampons, sexual intercourse) for a specified period.
   • Follow-up appointments are scheduled to ensure healing and address any concerns.

6. Potential Complications

While generally safe, the procedure can have complications, including:

• Immediate Complications:

  • Excessive Bleeding (Hemorrhage): May require uterotonics or blood transfusion.
  • Uterine Perforation: A rare event where the instrument may puncture the uterine wall; may require further surgical intervention.
  • Vasovagal Reactions: Resulting in hypotension or bradycardia.

• Delayed Complications:

  • Infection: Endometritis or pelvic inflammatory disease; managed with antibiotics.
  • Asherman’s Syndrome: Formation of intrauterine adhesions due to aggressive curettage, potentially affecting fertility.
  • Retained Products of Conception: May require repeat evacuation if tissue remains.

7. Nursing Responsibilities and Patient Education

Pre-procedure Nursing Care:

• Assessment & Preparation:
  • Verify patient identity, review history, and ensure all preoperative instructions (such as fasting and medication adjustments) are followed.
• Patient Education:
  • Explain the procedure, possible outcomes, and what to expect during recovery.
  • Provide counseling regarding potential emotional reactions—miscarriage or abortion can be stressful.

Intra-procedure Assistance:

• Support and Monitoring:
  • Assist with positioning and maintain sterility.
  • Monitor patient vital signs and provide reassurance during the procedure.

Post-procedure Nursing Care:

• Observation:
  • Monitor for signs of complications (e.g., heavy bleeding, pain, fever).
• Pain Management:
  • Administer prescribed analgesics and educate the patient about managing discomfort.
• Discharge Teaching:
  • Instruct on signs of infection, activity restrictions, and the importance of follow-up care.
  • Educate on when to resume normal activities, including sexual intercourse and use of tampons.
  • Provide written instructions and answer any questions regarding the recovery process.

8. Summary

Suction evacuation combined with curettage is an essential procedure in obstetrics and gynecology for managing early pregnancy loss, performing elective terminations, and diagnosing/treating uterine conditions. Nursing care is pivotal—from pre-procedure assessment and patient education through intraoperative support and post-procedure monitoring—to ensure patient safety and comfort. Understanding the detailed steps, the potential complications, and proper nursing interventions will help you provide high-quality care to patients undergoing this procedure.
