A protocol to initiate PCA for sickle cell patients in a pediatric emergency department shortened the time of its initiation and was preferred by patients.
ISSUES AND PURPOSE. To evaluate the characteristics of vaso‐occlusive episodes, home management of pain and its impact on the daily activities, and a diary as a method of data collection.
DESIGN AND METHODS. Forty‐six adolescents and 75 children were asked to complete daily diaries during the intervention period of a larger study.
RESULTS. Mild pain was recorded 95% of the time; moderate pain, 3%; and severe pain, 1%. The pattern and location of pain varied greatly. Adolescents used more interventions than did children. When pain intensity was mild, 80% of the children/adolescents maintained school, social, and home activities, but decreased play/sport activities. When pain intensity was high, they decreased their participation in all activities.
PRACTICE IMPLICATIONS. Sickle cell pain episodes are unpredictable and highly variable. Diaries can enhance children's and adolescents’documentation and communication about their pain experiences.
Chronic constriction injury to the sciatic nerve was used as an animal model of neuropathic pain. Instead of frequently used reflex-based tests we used an operant thermal place preference test to evaluate signs of neuropathic pain and the effect of baclofen administration in rats with neuropathy. Chronic constriction injury was induced by four loose ligations of the sciatic nerve. Thermal place preference (45 °C vs. 22 °C and 45 °C vs. 11 °C) was measured after the ligation and after the administration of baclofen in sham and experimental rats. Rats with the chronic constriction injury spent significantly less time on the colder plate compared to sham operated animals at the combination 45 °C vs. 11 °C. After administration of baclofen (10 mg/kg s.c.), the aversion to the colder plate in rats with chronic constriction injury disappeared. At the combination 45 °C vs. 22 °C, no difference in time spent on colder and/or warmer plate was found between sham and experimental animals. These findings show the importance of cold allodynia evaluation in rats with chronic constriction injury and the effectiveness of baclofen in this neuropathic pain model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
