| Abstract: | OBJECTIVES: to analyze the relationship between preoperative emotional state and the
prevalence and intensity of postoperative pain and to explore predictors of
postoperative pain. METHOD: observational retrospective study undertaken among 127 adult patients of
orthopedic and trauma surgery. Postoperative pain was assessed with the verbal
numeric scale and with five variables of emotional state: anxiety, sweating,
stress, fear, and crying. The Chi-squared test, Student''s t test or ANOVA and a
multivariate logistic regression analysis were used for the statistical analysis.
RESULTS: the prevalence of immediate postoperative pain was 28%. Anxiety was the most
common emotional factor (72%) and a predictive risk factor for moderate to severe
postoperative pain (OR: 4.60, 95% CI 1.38 to 15.3, p<0.05, AUC: 0.72, 95% CI:
0.62 to 0.83). Age exerted a protective effect (OR 0.96, 95% CI: 0.94-0.99,
p<0.01). CONCLUSION: preoperative anxiety and age are predictors of postoperative pain in patients
undergoing orthopedic and trauma surgery. |
