RESUMO
BACKGROUND: This study aimed at investigating the effect of showing surgery educational documentary film on the anxiety of patients candidate for lumbar disc surgery. MATERIALS AND METHODS: This study, as a randomized clinical trial, was conducted in 2018 on 60 patients undergoing lumbar disc surgery, Iran. The patients were divided into two groups of intervention and control (N = 30). An educational film was shown to the patients of the intervention group for 20 min and the control group was provided with the ward's routine trainings. All patients completed demographic characteristics questionnaire and the Spielberger State-Trait Anxiety Inventory (SSTAI) on the admission day, 1 day before the surgery, and 2 h before the surgery. SSTAI was recompleted by the patients. Data analysis was performed using independent t-test, Chi-square, Mann-Whitney test, and paired t-test. RESULTS: Before the intervention, the mean score of the state (obvious) and trait (hidden) anxieties was not significantly different between the two groups, but after the intervention, the mean [standard deviation (SD)] score of the state anxiety in the intervention group was significantly lower than that of the control group [mean (SD) = 40.78 (10.34) vs. 47.45 (10.33), F 10,33 = 58, p = 0.01]. In addition, after the intervention, the mean (SD) anxiety score of the patients in the intervention group was significantly lower than that of the control group [mean (SD) = 38.65 (11.01) vs. 44.71 (10.34), F 10,34 = 58, p = 0.03). CONCLUSIONS: The results showed that educational film reduces the patients' level of anxiety before the surgery. As such, it is recommended that these trainings be included in preoperative nursing practices.
RESUMO
BACKGROUND: After single disk herniation operation, about 5-20% recurrences may occur. Different etiology may affect the prevalence of recurrence. Disk degeneration according to Modic and Los Angles scales could affect recurrence rate. This study wants to show the relationship between disk space degeneration according to these scales on severity, time, and prevalence of disk herniation recurrence. MATERIALS AND METHODS: Thirty-four patients presented with radicular pain (with or without back pain) and history of lumbar disk surgery was included in this prospective study. Pre- and postoperative T2-weighted sagittal magnetic resonance imaging (MRI) compared for Modic and Los Angeles disk degeneration grading, then, data analysis on SPSS (version 20) software, paired t-test, and others. RESULTS: The result of study shows for first operation that grade (II) Los Angeles is the most common, but, for second procedure grade (IV) was less common and the mostly decreased (from 14.7 to 9.2%). In addition, Wilcoxon test shows no change of Los Angeles grading for both first and second surgery (P = 0.06). Whereas; based on Modic criteria grading was different from first operation, in other words, grade (I) (41.2%) in first operation was changed to 20.6% in second operation (P = 0.007). CONCLUSION: Our study showed that the Los Angeles criterion is more practical and useful for prediction of recurrence and in the patients with Los Angles grade III and IV and grade II and III on Modic scale, the chance of recurrence is less than patients with lower grades.
