Efficacy and Safety of Acetaminophen in Postoperative Pain Management of Infants
Study Details
Study Description
Brief Summary
Pain will bring early and long-term adverse reactions to infants. The investigators need to pay attention to whether there is pain in infants after surgery. Since infants cannot self-report pain,The investigators need to use appropriate pain assessment scale to evaluate the pain of these infants, so as to understand the status of postoperative pain in children. The result of pain score not only enables investigators to understand the pain status of children, but also helps investigators to give corresponding intervention and treatment according to the pain degree of children. Postoperative pain management is one of the core contents of ERAS. Effective pain management is beneficial to the early postoperative recovery of infants and reduces the adverse reactions caused by pain. Sveral studies have confirmed that the combination of acetaminophen and opioids could reduce the use of opioids after surgery. But even if opioid use is reduced, it still causes many side effects for children. This study evaluated the safety and efficacy of acetaminophen alone for postoperative analgesia in infants.

Experimental: Treatment group After recovering and returning to the ward, acetaminophen (10mg/kg) was taken orally immediately; once every 6 hours, a total of 4 times. |
Drug: Acetaminophen
When the infants woke up after surgery and were transported back to the ward, they were randomly divided into two groups immediately. The intervention group was given oral acetaminophen, once every 6 hours, for a total of 4 times.

Placebo Comparator: placebo group The same amount of sterilized water was administered orally at the same time points. |
Drug: Sterilized water
When the infants woke up after surgery and were transported back to the ward, they were randomly divided into two groups immediately. The control group was given sterilized water, once every 6 hours, for a total of 4 times.
