Abstract BACKGROUND: Anxiety is defined as a set of behavioural manifestations that can be divided into state- and trait-anxiety. State-anxiety is a transitory emotional condition that varies in intensity and fluctuates over time. Trait-anxiety is a personality trait which remains relatively stable over time. The objective of this study was to identify and quantify perioperative risk factors for immediate postoperative anxiety in children. METHODS: A prospective cohort study was performed with 90 schoolchildren, ages ranging from 7 to 13 years old, ASA physical status I-II, submitted to elective surgery. The measuring instruments were verbal scale of pain, visual analogue scale (VAS), Trait-State Anxiety Inventory for Children (STAIC), Trait-State Anxiety Inventory (STAI) for parents, and structured questionnaire. RESULTS: Patients not submitted to analgesic block and patients with moderate and intense pain presented an estimated risk 5- and 13-fold greater for high levels of postoperative state-anxiety, respectively. High levels of preoperative state-anxiety and administration of doses of midazolam less than 0.056 mg x kg(-1) constituted an estimated risk for postoperative state-anxiety of 3- and 4-fold, respectively. A positive history of previous surgery was associated with lower risk for postoperative anxiety. CONCLUSIONS: High levels of preoperative state-anxiety, administration of less than 0.056 mg x kg(-1) of midazolam, absence of analgesic block and presence of moderate and intense postoperative pain constituted risk factors for immediate postoperative state-anxiety in children. Previous surgery reduced the risk for postoperative anxiety. No: 1 FI: 2.58 Citações: 97 Anaesthesia. 2001 Aug;56(8):720-8.
Risk factors for postoperative anxiety in adults. Caumo W1, Schmidt AP, Schneider CN, Bergmann J, Iwamoto CW, Adamatti LC, Bandeira D, Ferreira MB.
We identified risk factors for postoperative anxiety and quantified their effect on 712 adults between 18 and 60 years of age (ASA I-III physical status) undergoing elective surgery under general anaesthesia, neural blockade or both. The measuring instruments were a structured questionnaire, a pain visual analogue scale, the McGill Pain Questionnaire, the State-Trait Anxiety Inventory, the Montgomery-Asberg Depression Rating Scale, a Self-Reporting Questionnaire-20, and a Self-Perception of Future Questionnaire. Multivariate conditional regression modelling taking into account the hierarchical relationship between risk factors revealed that postoperative anxiety was associated with ASA status III (OR = 1.48), history of smoking (1.62), moderate to intense postoperative pain (OR = 2.62) and high pain rating index (OR = 2.35), minor psychiatric
