Official Title: | A Randomized Controlled Trial Evaluating Lanolin for the Treatment of Nipple Pain Among Breastfeeding Women |
Study Start Date : | May 2011 |
Actual Primary Completion Date : | February 2012 |
Actual Study Completion Date : | March 2012 |

Arm | Intervention/treatment |
---|---|
Experimental: Lanolin
Pea sized amount of lanolin to be applied to nipple and areola after every breast feed (approximately every 2-3 hours), until pain is completely resolved for a maximum of 7 days
|
Other: Lanolin
Pea-sized amount of lanolin applied to each nipple after every breastfeeding session (approximately 8-12 times daily) until complete resolution of nipple pain and damage for a maximum of 7 days. |
Standard postpartum nursing care
Women in standard care control group may receive any other nursing intervention to manage their nipple pain, including (but not limited to): recommending application of expressed breast milk, analgesics (such as acetaminophen or ibuprofen), breast shells, air drying, changing position / latch, cold or warm compresses
|
Other: Standard (usual) in-hospital and community postpartum care
Women randomized to standard care will not receive lanolin or information regarding how to use lanolin. In-hospital standard care may include any of the following pain management measures at the recommendation / discretion of the participant's health care provider, or based on the patient's personal preference: analgesics (such as ibuprofen or acetaminophen); application of cold or warm compresses; application of ice packs; use of breast shields; air drying the nipples; or applying expressed breast milk. |
- Nipple pain severity [ Time Frame: 4 days post randomization ]Measured with a 10-point numeric rating scale (NRS)
- Breastfeeding duration [ Time Frame: 4 and 12 weeks postpartum ]Measured by asking women the last time their infant was breastfed. Breastfeeding duration will be calculated as the difference between the infant's date of birth, and the last day (date) the infant was breastfed.
- Breastfeeding exclusivity [ Time Frame: 4 and 12 weeks postpartum ]Measured with Labbok & Krasovek's framework for breastfeeding definition (Studies in Family Planning, 1990;21(4),226-230)
