Evaluation of the analgesic effect of subcutaneous methadone after cesarean section
Inadequate pain control has a significant role in maternal and neonatal health in early post-partum period which interferes with breastfeeding and has a negative influence on child normal growth. The aim of this study is evaluation of subcutaneous methadone effectiveness on post-operative pain control.
Double blind randomized prospective clinical trial involving 60 term pregnancy patients through 2008 to 2009 Undergo cesarean. Inclusion criteria: Prime gravid candidate of elective cesarean and spinal anesthesia class 1 or 2. Known case of drug allergy and methadone interaction, addiction, uncontrolled medical disease excluded. Case group injected 10 mg of subcutaneous methadone in the site of incision before final suture. Morphine was a pain reliever in follow up examination. Data include mean of pain, nausea and vomiting, MAP, etc., collected and analyzed by independent-T test and Man Whitney test.
Although mean usage of morphine between groups was not significant statistically but the mean pain severity (P value < 0.05) and mean satisfactory (P value = 0.02) was statistically significant between groups. Other parameters were not statistically significant.
We suggest subcutaneous methadone as a safe pain reliever in post cesarean section patients.
