Three Part Question
In [woman with primary dysmenorrhea] is [heat application] a comparable alternative to [pain killers] at [decreasing pain]?Clinical Scenario
A 16 year old girl presents to her general practitioner, monthly she suffers from dysmenorrhea. Her dysmenorrhea is often associated with vomiting and therefore her mother does want to know if a non-pharmaceutical therapy can reduce the pain as well. You wonder if applied heat is as effective in providing menstrual pain relief and reduction of abdominal cramping as pain killers.Search Strategy

|---|---|---|---|---|---|
| Akin M et al. 2001 USA | 79 woman with primary dysmenorrhea who received over 2 days (12h/day) a) an abdominal heated patch or b) an oral medication (ibuprofen 200mg) c) double placebo (patch and tablets) | Randomised controlled trial (level of evidence 1b) | Mean pain relief during 2 days (score 0-5) | a) vs c) 3.27 vs 1.95 (p<0.001); b) vs c) 3.07 vs 1.95 | Small study population. |
| Akin M et al. 2004 USA | 344 healthy premenopausal adult woman with primary dysmenorrhea who received over 8 hours a) an abdominal heat wrap or b) oral medication(acetaminophen-1000 mg) | Randomised controlled trial (level of evidence 1b) | Mean pain relief day 1 (0-8h) (score 0-5) | (2.48 ± 0.10 vs 2.17 ± 0.10; p= 0.015) | |
| Mean abdominal muscle tightness/cramping day 1 (0-8h) (0-100) | (40.4 ± 1.64 vs 44.5 ± 1.67; p=0.040) |
Comment(s)
Evidence from one study showed that heat application as well as the use of pain killers resulted in a comparable statistically significantly higher pain relief during menstrual pain, when compared to placebo treatment (Akin M, 2001). Evidence from another study showed that continuous topical heat application resulted in a statistically significantly higher pain relief and lower muscle tightness/cramping during menstrual pain, when compared to pain killers (Akin M, 2004).Clinical Bottom Line
Heat application is a good alternative to pain killers in case of dysmenorrheal pain.References
