Insights
Ketorolac and metamizol effectively provided preventive analgesia in children undergoing surgery, with no significant differences between the two drugs. Both medications helped prevent post-surgical hyperalgesia without affecting blood counts or bleeding times.
Area of Science:
- Pediatric Anesthesiology
- Pharmacology
Background:
- Preventive analgesia is crucial for managing post-surgical pain in children.
- Non-opioid analgesics are preferred to minimize side effects.
Purpose of the Study:
- To compare the efficacy of ketorolac and metamizol for preventive analgesia in pediatric surgery.
- To evaluate the impact of these analgesics on post-operative pain and safety parameters.
Main Methods:
- A prospective, randomized study involving 120 children aged 3-6 years undergoing various surgical procedures.
- Intravenous administration of ketorolac or metamizol 15 minutes before surgery under inhaled general anesthesia.
- Pain assessment using modified McGrath scales and chromatic EVA; monitoring of bleeding time, platelet count, and white blood cell count.
Main Results:
- Both ketorolac and metamizol showed comparable efficacy in preventing post-surgical pain, with no statistically significant difference (p > 0.5).
- 40% of children in both groups experienced no pain, and 55% reported mild to moderate pain.
- No significant alterations were observed in bleeding time, platelet count, or white blood cell count.
Conclusions:
- Ketorolac and metamizol are effective in providing preventive analgesia for pediatric surgical patients.
- Both agents successfully prevent post-surgical hyperalgesia without adverse effects on hematological parameters or hemostasis.
Abstract:
Preventive analgesia produced by ketorolac and metamizol was evaluated during a prospective study randomized in two groups. One hundred twenty children were included aged from 3 to 6 years who underwent surgery by different procedures. Analgesic dose was applied 15 min prior to surgery by intravenous (i.v.) via. Technique used was inhaled general anesthesia; use of opioids was avoided. Pain evaluation at the end of surgery (and during the following 48 to 72 h) as well as bleeding time, platelet count, and alterations in white blood cell count were dependent variables. As soon as patients arrived in the recovery room, pain was measured by modified McGrath scales and the chromatic EVA. In ketorolac group, 40% of children showed no pain and 55% presented mild to moderate pain (1-6). In metamizol group, 40% of children referred no pain, while 55% evaluated pain as minimal to moderate. Analgesia produced by both drugs presented no significant statistical diference (p > 0.5). Troughout followup, maximum pain referred had a values of 6 and 7, respectively, for ketorolac and metamizol. Fifteen min after analgesic dose, pain was referred as 3 and 4. No alterations were observed in bleeding time, platelet count, and white blood cell count. We conclude that both analgesics prevent hyperalgesia during post-surgical period.
