Although it is known that parecoxib and dexketoprofen are commonly used in successful post-operative pain relief, there are very few studies that compare these two agents in their individual applications and/or combined with neuraxial analgesia with opioids and even less in post-cesarean section pain, as well as the evaluation of the side effects and their impact on the patient's functionality. For this reason, in order to approach this answer, we sought to perform this study in patients undergoing elective or emergency cesarean section in our institution, who meet the inclusion criteria, using the Visual Analog Pain Scale at 12 hrs and 24 hrs post surgery and evaluating the aforementioned side effects, comparing in one arm of the study Parecoxib + acetaminophen vs Dexketoprofen + acetaminophen in the other arm, randomizing the patients in both groups using a double-blind configuration.

Inclusion Criteria:

• Pregnancy 32w or more.
• Emergency or elective caesarean section.

Exclusion Criteria:

• Allergy to Parecoxib.
• Allergy to dexketoprofen.
• Allergy to acetaminophen.
• General anesthesia.
