Abstract:
Objective To investigate the analgesic effects of inhaling 50% nitrous oxide on burn pediatric patients during and after dressing change. Methods A total of 120 burn pediatric patients received outpatient dressing and hospitalized from September 2012 to September 2014 were enrolled in our study, and they were all in accordance with the inclusion criteria. The 120 pediatric patients were divided into control group (n=30) treated with inhalation of oxygen during dressing change) and treatment group (n=90) treated with inhalation of 50% nitrous oxide during dressing change ) according to the computer-generated list of random number. The other treatments in control group and treatment group were the same. Before, during and after dressing change, degree of pain, heart rate, systolic blood pressure, diastolic blood pressure, oxygen saturation and adverse effects were observed at the same time points. Data were processed with analysis of chi-square test, covariance and Student′s t test. Results There were no significant differences between the two groups in levels of HR, SBP, DBP, and SpO2 before dressing change (t=0. 34, 0. 57, 0. 11, 0. 98, respectively;P>0. 05). Compared with those of control group, levels of HR, SBP, DBP, and SpO2 in treatment group were significantly ameliorated during dressing change (t=25. 96, 24. 11, 8. 37, 20. 29, respectively;P<0. 01). After dressing change, the levels of DBP in the two groups were close (t=1. 57,P>0. 05), but the levels of HR, SBP, and SpO2 showed statistical differences (t=5. 20, 8. 64, 3. 37, respectively;P<0. 01). Before dressing change, the pain scores were approximate between control group and treatment group (t=0. 18,P>0. 05). Compared with those in control group, the pain scores in treatment group during and after dressing change were (2. 82 ± 0.8) and (1.2 ±0. 84), which were significantly lower than those in the control group (t =23. 00, 4. 30, respectively;P<0. 01). There were no obvious adverse effects in two groups during and after dressing change. The results of the covariance analysis of pain scores during dressing change showed statistical differences ( F=867. 956,P <0. 01). Conclusions 50% nitrous oxide seems to have obvious analgesic effects on burns pediatric patients during dressing change, and it can be widely used.
