What is the recommended procedure for a medical termination of pregnancy (MTP) at 6 months gestation?

Medical Termination of Pregnancy at 6 Months Gestation

For medical termination of pregnancy at 6 months gestation, dilation and evacuation (D&E) is the recommended procedure as it has the lowest complication rates compared to medical methods and should be performed in a hospital setting by experienced providers. 1

Recommended Procedures

Surgical Method (Preferred)

• Dilation and evacuation (D&E) is the safest procedure for second-trimester termination with significantly lower rates of hemorrhage (9.1% vs 28.3%) and infection (1.3% vs 23.9%) compared to medical methods 1, 2
• D&E should be performed in a hospital setting by experienced providers to minimize complications 1
• Most D&E procedures are performed with sedation or general anesthesia for patient comfort 1

Medical Method (Alternative)

• If D&E is not available or feasible, medical termination can be performed using prostaglandin regimens 1
• The most common regimen involves mifepristone followed by misoprostol, though repeated doses may be required at this advanced gestational age 2
• Medical termination at this gestational age has higher complication rates and should be performed in a hospital setting with close monitoring 2

Procedural Considerations

Pre-Procedure

• Thorough counseling should be provided regarding both surgical and medical options 2
• Baseline assessment of patient's health status should be performed 3
• For high-risk patients, management in experienced centers with appropriate emergency support services is recommended 3

During Procedure

• Systemic arterial oxygen saturation should be monitored with transcutaneous pulse oximetry during prostaglandin administration if medical method is used 1
• Close monitoring of vital signs and bleeding is necessary during the procedure 3
• Fetal analgesia is not recommended as there is no evidence of fetal pain awareness before 24-25 weeks gestation 1, 2

Post-Procedure Care

• Antibiotic prophylaxis is recommended to prevent post-abortal endometritis, which occurs in 5-20% of women not given antibiotics 1, 2
• Rh-negative women should receive anti-D immunoglobulin to prevent alloimmunization 1, 2
• Monitor for signs of infection, retained products, and excessive bleeding 2

Special Considerations

Timing Considerations

• At 6 months gestation (approximately 24 weeks), termination procedures require specialized expertise due to increased risks 1
• The method chosen should be based on provider expertise and facility capabilities 1
• In cases where pregnancy termination is related to maternal health concerns (e.g., cancer requiring treatment), the timing of the procedure should be carefully planned to minimize delays in maternal treatment 4

Complications to Monitor

• Higher risk of bleeding with medical methods compared to surgical methods 1, 2
• Risk of incomplete abortion requiring additional intervention 5
• Potential for infection, which can be significantly reduced with prophylactic antibiotics 1

Important Caveats

• The choice between surgical and medical methods should prioritize patient safety and complication risk, with D&E being the preferred method at this gestational age 1, 2
• Provider experience is crucial for second-trimester procedures, particularly for D&E 1
• High-risk patients should be managed in experienced centers with appropriate emergency capabilities 3
• Emotional support should be provided throughout the process 2
