  Purpose

The aim of this study is to compare the effect of pre-procedural ketorolac to ibuprofen on immediate post-procedural pain scores in patients undergoing first trimester suction curettage with local anesthesia only.

Our primary hypothesis is that IM ketorolac compared to oral ibuprofen will result in an approximate 30% reduction in pain scores on a 21-point numerical rating scale immediately after the procedure.

Secondary hypotheses include:

  • Pain scores on the 21-point scale will also be significantly lower in the ketorolac group immediately after cervical dilation and 15 minutes post-procedure.
  • Fewer patients in the ketorolac group will rate their pain as "severe" on a subjective pain rating scale.
  • Patients in the ketorolac group will be more satisfied with their pain control.
  • Side effects will be similar between groups.

Primary Outcome Measures:
  • Immediate Post-procedure Pain Score [ Time Frame: Immediately (within 1 minute) after suction and speculum removal ] [ Designated as safety issue: No ]
    The primary endpoint is subjects' immediate post-procedure pain score on a 21-point 0 to 100 scale, 0 = no pain and 100 = worst possible pain (in increments of five). This scale has been previously validated and used for research purposes, including for pain research evaluating suction curettage elsewhere and at our institution (Jensen 1986, Williamson 2004, Allen 2009).


Secondary Outcome Measures:
  • Pain Scores Immediately After Cervical Dilation [ Time Frame: Immediately (within 1 minute) after cervical dilation prior to the introduction of the suction cannula ] [ Designated as safety issue: No ]
    21-point 0 to 100 scale where 0 = no pain and 100 = worst possible pain (in increments of five)

  • Pain Scores 15 Minutes Post-procedure [ Time Frame: Fifteen minutes after the procedure ] [ Designated as safety issue: No ]
    21-point 0 to 100 scale, where 0 = no pain and 100 = worst possible pain (in increments of five)

Arms Assigned Interventions
Experimental: Ketorolac
Intramuscular injection of ketorolac 60 mg in 2cc -plus- placebo tablet (calcium carbonate 600 mg tablet). For subjects who are 50 kg or less, intramuscular injection of ketorolac 30 mg in 1cc -plus- placebo tablet (calcium carbonate 600 mg tablet)
Drug: Ketorolac
For subjects weighing over 50 kg, ketorolac 60 mg in 2cc administered via intramuscular injection 30-60 minutes before suction curettage procedure. For subjects weighing 50 kg or less, ketorolac 30 mg in 1 cc administered via intramuscular injection 30-60 minutes before suction curettage procedure
Other Name: Toradol
Active Comparator: Ibuprofen
Ibuprofen 800 mg tablet -plus- intramuscular injection of 2cc saline placebo. For subjects weighing 50 kg or less, ibuprofen 600 mg tablet -plus- intramuscular injection of 2cc saline placebo
Drug: Ibuprofen
For subjects weighing over 50 kg, ibuprofen 800 mg tablet administered orally 60-90 minutes before suction curettage procedure. For subjects weighing 50 kg or less, ibuprofen 600 mg tablet administered orally 60-90 minutes before suction curettage procedure.
