Brief summary

This study aims to compare an algorithm for IV sedation dosing to the current standard of care in patients undergoing first trimester surgical abortion. The primary outcome is subjects' pain score with suction curettage on a 0-100 21-point scale. Secondary outcomes include pain scores with cervical dilation and 15 minutes post-procedure, subjective pain ratings, incidents of side effects and adverse events, the frequency of additional doses of medication, recovery room time, and physician assessment of and satisfaction with pain control. Investigators hypothesize that this algorithm will result in improved pain control, decreased frequency of additional medication doses, improved patient and physician satisfaction, without differences in side effects, adverse events or recovery room time.

Inclusion criteria

* Women age 18 or older seeking surgical abortion at Planned Parenthood League of Massachusetts (PPLM) * Gestational age less than or equal to 13+6, confirmed by ultrasound * Eligible for surgical abortion according to PPLM protocols * Eligible for IV sedation per PPLM protocol, and desiring IV sedation for pain management

Exclusion criteria

* Choice of local anesthesia for pain control * Hypersensitivity to midazolam or fentanyl * Ineligible for IV sedation per PPLM protocol * Need for cervical ripening with either misoprostol or mechanical priming agent (laminaria/Dilapan) * Unable or unwilling to complete required study procedures * Previous participation in the study

Design outcomes

Primary

MeasureTime frameDescription
Pain with suction curettageMeasured on Day 1 (day of enrollment), immediately (within one minute) after completion of suction curettage and speculum removalSubjects' pain score with suction curettage on a 0-100 21-point scale

Secondary

MeasureTime frameDescription
Pain with paracervical blockMeasured on Day 1 (day of enrollment), immediately after paracervical blockPain with paracervical block will be measured (a) on a 21-point 0 to 100 scale (in increments of five), and (b) on a subjective scale of no pain, mild pain, moderate pain or severe pain. Pain will be measured immediately after paracervical block.
Pain with cervical dilationMeasured on Day 1 (day of enrollment), immediately after cervical dilationPain with cervical dilation will be measured (a) on a 21-point 0 to 100 scale (in increments of five), and (b) on a subjective scale of no pain, mild pain, moderate pain or severe pain. Pain with cervical dilation will be measured immediately after cervical dilation.
Post-operative painMeasured on Day 1 (day of enrollment), 15 minutes post-operativelyPost-operative pain will be measured (a) on a 21-point 0 to 100 scale (in increments of five), and (b) on a subjective scale of no pain, mild pain, moderate pain or severe pain. Pain will be measured 15 minutes post-operatively when the patient is in the recovery room.
Patient satisfaction with pain controlMeasured on Day 1 (day of enrollment), 15 minutes post-operativelyPatients will be asked about their general satisfaction with pain control, what their pain was compared to what they expected, whether they would chose the same pain management strategy again, and whether they would recommend their strategy of pain management to a friend.
Side effectsMeasured on Day 1 (day of enrollment), 15 minutes post-operativelyInvestigators will assess side effects for all patients, including nausea, vomiting, dizziness, and drowsiness.

Other

MeasureTime frameDescription
Doses given over the duration of the studyMeasured on Day 1 (day of enrollment), intraoperativelyTo assess whether use of the algorithm changes physician's behavior in the standard care arm, investigators will also examine doses given over the duration of the study, to see if a learning curve develops among the physicians based on their experience with the algorithm.
Physician assessment of pain controlMeasured on Day 1 (day of enrollment), post-operativelyInvestigators will also have the physician assess patients' pain control, whether they felt the dose was appropriate and how easy or difficult it was to determine the patients' doses of pain medication.
