The comparative safety of second-trimester abortion methods.

D A Grimes, K F Schulz

    Ciba Foundation Symposium
    |January 1, 1985
    PubMed
    Summary

    Dilatation and evacuation (D&E) is the safest method for second-trimester abortion, posing fewer serious complications than instillation methods, hysterotomy, or hysterectomy. This finding is crucial for public health and patient safety in abortion care.

    Area of Science:

    • Medical and Health Sciences
    • Reproductive Health
    • Public Health

    Background:

    • Second-trimester abortion methods require careful safety evaluation.
    • Previous studies suggest varying risk profiles for different abortion procedures.

    Purpose of the Study:

    • To compare the safety of various second-trimester abortion methods.
    • To assess the relative risks of complications and mortality associated with different procedures.

    Main Methods:

    • Comparative analysis of morbidity and mortality data.
    • Review of surveillance data on abortion mortality in the United States (1972-1981).
    • Statistical analysis of relative risks for serious complications.

    Main Results:

    • Dilatation and evacuation (D&E) demonstrated a lower risk of serious complications compared to instillation methods.
    • The adjusted relative risk of complications for instillation was 1.9 times that of D&E.
    • Mortality rates per 100,000 abortions: D&E (4.9), instillation (9.6), hysterotomy/hysterectomy (>60).

    Conclusions:

    • D&E is identified as the safest available method for second-trimester abortion in the United States.
    • Instillation methods carry a significantly higher risk of complications than D&E.
    • Hysterotomy and hysterectomy present the highest mortality risks for second-trimester abortion.
