Curative Effect of Analgesia in 11 Children with Cancer Pain

Objective To study analgesia in children with cancer pain. Methods Clinical data of children ad- mitted during June 2009 to January 2010 with cancer pain were analysed. Results 11 pediatric patients aged from 0-12 （ Mean = 5.70 yrs） with cancer pain were treated（6/M and 5/F） , including 5 cases （45.5%） of bone and soft tissue sarcomas,2 cases （ 18.2% ） of lymphoma and nephroblastoma respectively, 1 case（9. 1% ） of hepatoblastoma and retinoblastoma respectively, 5 cases of somatalgia and visceral pain respectively and 1 case of mixed pain （ somatalgia and nerve pains）. Pain severity： 4 （36.4%） was moderate and 7 （63.6%） was severe. 6 （54.5%） the patients had taken analgesic therapy before being admitted into our hospital. All the children were treated under WHO＇s pediatric cancer pain guideline： 2 cases were given Oxycodone and Acetaminophen tablets, 3 cases were treated by instant released Morphine and another 6 children took controlled Oxycodone tablets. 2 patients with bone and soft tissue sarcomas and one with mixed pain took Dexmathathone as co-analgesics. 1 patient had Buluofen as a combination. Pain intensity decreased in all patients after treatment： one mild relief case, 5 medium relief cases, 4 obvious relief cases and one complete relief case with a rate of 91.0%. The common side effects were constipation （4 cases： 36.4% ） ; nausea and vomiting （2 cases： 18.2% ）and one itchy skin and one dizziness case （9.1%）. Conclusion An extensive evaluation of pain should be made and a suitable combination of different analgesics can effectively reduce cancer pain in pediatric patients.
