Primary Outcome Measures
NameTimeMethod
Expected outcome 1. One of the drugs was expected to show superior analgesic potency during labor. The avaluations were carried out between 5/20/2016 and 12/31/2016 ;Found outcome 1. The pain was measured by the visual analog scale just before the intervention, 1 hour and 2 hours after the intervention. Statistical evaluation was done using Student's t-test, ranging up to 1 standard deviation for more or less, at a significance of 5% and a 95% confidence interval. Similar analgesic effect occurred with the 2 drugs 1 hour after the intervention. One hour after the intervention, the score attributed to pain in participants who used Dipirone was 7.97 ± 1.226 and after Pethidine was 8.04 ± 1.271, with a p-value of 0.697. Two hours after the intervention, the two drugs did not present a statistically significant analgesic effect. The avaluations were carried out between 5/20/2016 and 12/31/2016
