Pain and Medical Abortion Among Teenaged Women Compared to Adult Women

September 26, 2018 updated by: Venla Kemppainen, Helsinki University Central Hospital

Pain and Medical Abortion - Predicting Factors of Pain and Optimal Pain Management Among Teenaged Women Compared to Adult Women

In this two-parted study the need and sufficiency of analgesics and experienced pain is compared between teen-aged and adult women undergoing medical termination of pregnancy (MToP)in early pregnancy (under 9weeks of gestation). During MToP at pregnancy weeks 9-20 on-demand administration of opiates and patient-controlled analgesia (PCA) are compared in randomized clinical trial.

Detailed Description

Adequate pain control is crucial in medical abortion. Experience of painful and traumatic abortion can affect patients future plans on pregnancy and childbirth. Study's purpose is to investigate only pain experience and pain management. Otherwise the care of abortion is according to present Finnish national guideline.

Study's goal is to evaluate experienced pain and the need and adequacy of analgesics and to obtain more efficient analgesics during MToP. In addition investigators hope to recognize predicting factors of severe pain.

Study is done in cooperation with Helsinki university and Helsinki university central hospital and is accomplished in Womens hospital and Kätilöopisto hospital in which care of abortions is centralized in HUS area.

Altogether 340 women, who are primigravid, aged between 15-19 or 25-35 years and tolerate used analgesics, are recruited in the study. MToP is done with the combination on mifepristone 200mg and misoprostol 800ug according to Finnish national guidelines. Baseline analgesics are Ibuprofein 600mg ja Paracetamol 1000mg, both three times a day and first dose is taken simultaneously with Misoprostol.

First part is a prospective study in which we compare pain experience and sufficiency of analgesics during MToP in early pregnancy (under 9 weeks of pregnancy). Pain is measured by VAS, which is reported in a diary every time analgesics are needed.

Second part is a controlled randomized study with PCA and on-demand pain management during medical termination of pregnancy with gestational age of 9 to 20 weeks. Every teen-aged woman has two adult controls.

Against severe pain patients get Opiates (oxycodone). In intervention group patients get PCA with Oxycodon dose of 3.0 mg maximal four times in an hour. In control group Oxycodon is administrated on demand po, im or iv depending on the intensity of pain. Pain is measured by VAS from the onset of pain and repeated every 30 minutes until fetal expulsion.

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Pain management in early pregnancy MTOP
Patients in early pregnancy (pregnancy weeks <9weeks) undergoing medical termination of pregnancy gets Ibuprofen (tbl 600mg 3 times a day) and Paracetamol (tbl 1000mg 3 times a day).
Experimental: Patient controlled analgesia (PCA)

Pregnancy weeks 9-20. All patients get baselineanalgesics: Ibuprofein 600mg and Paracetamol 1000mg both x3 a day.

Patients get pain medication (Oxynorm) via PCA

We compare different routes of administration (PCA an oral/intramuscular use of oxynorm) in patients undergoing medical termination of pregnancy. Patients are randomized in two groups (for extra pain medication)

  1. If analgesia is inadequate oxycodon (OxyNorm®) (10 mg (less than 80 kg) - 15 mg (over 80 kg) po. In an hour oxycodon 5-10 mg more po if needed. Intramuscular or intravenous administration if needed.
  2. Patient controlled analgesia (PCA pain pump): Oxycodon dose is 3.0 mg (3 ml) and lock-out time 8 min. Maximum four doses in hour. Dose can be lowered or augmented 0,5 mg at time between 2.0-4.0 mg and maximal number of doses can be up to 5.
Active Comparator: Oxynorm on-demand

Pregnancy weeks 9-20. All patients get baselineanalgesics: Ibuprofein 600mg and Paracetamol 1000mg both x3 a day.

Patients get extra pain medication (Oxynorm) on-demad from the nurse.
