Background. Moderate to severe postoperative pain affects performance of daily activities and it contributes to persistent postoperative pain. In patients submitted to cesarean section, this pain can also interfere with women's ability to care for their babies, to effectively breastfeed, and to satisfactorily interact with their children. Factors influencing the pain perception during the immediate postoperative period have not been widely pursued. Objective. To investigate the incidence and predicting factors of postoperative pain after cesarean section. Methods. A prospective longitudinal study with 1,062 women submitted to cesarean section. We collected sociodemographic, clinical, surgical, and health behavior data. We used the 11-point Numerical Pain and the Hospital Anxiety and Depression Scales. We performed logistic analysis to identify predictors of moderate to severe postoperative pain. Results. The incidence of moderate-severe postoperative pain was 78.4% (CI: 95%: 75.9%–80.8%). The preoperative anxiety (OR = 1.60; CI 95%: 1.22–2.30) and intrathecal morphine with fentanyl (OR = 0,23; CI 95%: 0.08–0.66) were significantly associated with moderate-severe postoperative pain report. Conclusion. The preoperative anxiety increases the risk of moderate-severe postoperative pain in women submitted to cesarean section. The intrathecal morphine with fentanyl added to bupivacaine was a protective factor against this pain.

Objective:to estimate the prevalence and factors associated with preoperative anxiety in children who wait for outpatient surgery. Method:cross-sectional analysis of baseline data of a prospective cohort study that investigates the predictors of postoperative pain in children aged 5-12 years submitted to inguinal and umbilical hernia repair. It was selected 210 children, which were interviewed in the preoperative holding area of a general hospital. Anxiety was evaluated using the modified Yale Preoperative Anxiety Scale (mYPAS). Sociodemographic and clinical variables were analyzed as exposure and anxiety (mYPAS final score>30) as outcome. Logistic regression was used to identify factors associated with preoperative anxiety. Results:forty-two percent (42.0%) of children presented preoperative anxiety (CI95%: 35.7%-48.6%), with mean scores equal to 30.1 (SD=8.4). Factors associated with preoperative anxiety were: age group of 5-6 years (OR=2.28; p=0.007) and socioeconomic status classified as class C (OR=2.39; p=0.016). Conclusion:the evaluation of children who wait for outpatient surgery should be multidimensional and comprise information on age and socioeconomic status, in order to help in the identification and early treatment of preoperative anxiety.

Background Chronic post-surgical pain (CPSP) is one of the post-surgical complications of a Cesarean section. Despite the high rates of Cesarean section worldwide, the incidence of CPSP and the risk factors for this condition remain relatively unknown. The objective of this study was to calculate the incidence of CPSP in women submitted to Cesarean section and to analyze the associated risk factors. Materials and methods A prospective cohort of 621 women undergoing Cesarean section was recruited preoperatively. Potential presurgical (sociodemographic, clinical and lifestyle-related characteristics) and post-surgical risk factors (the presence and intensity of pain) risk factors were analyzed. Pain was measured at 24 hours and 7, 30, 60 and 90 days after surgery. Following discharge from hospital, data were collected by telephone. The outcome measure was selfreported pain three months after a Cesarean section. The risk factors for chronic pain were analyzed using the log-binomial regression model (a generalized linear model). Results A total of 462 women were successfully contacted 90 days following surgery. The incidence of CPSP was 25.5% (95%CI: 21.8-29.7). Risk factors included presurgical anxiety (adjusted relative risk [RR] 1.03; 95%CI: 1.01-1.05), smoking (adjusted RR 2.22; 95%CI: 1.27-3.88) and severe pain in the early postoperative period (adjusted RR 2.79; 95%CI: 1.29-6.00).

Objective: Correlating two unidimensional scales for measurement of self-reported pain intensity for elderly and identifying a preference for one of the scales. Method: A study conducted with 101 elderly people living in Nursing Home who reported any pain and reached > 13 the scores on the Mini-Mental State Examination. A Numeric Rating Scale -(NRS) of 11 points and a Verbal Descriptor Scale (VDS) of five points were compared in three evaluations: overall, at rest and during movement. Results: Women were more representative (61.4%) and the average age was 77.0±9.1 years. NRS was completed by 94.8% of the elderly while VDS by 100%. The association between the mean scores of NRS with the categories of VDS was significant, indicating convergent validity and a similar metric between the scales. Conclusion: Pain measurements among institutionalized elderly can be made by NRS and VDS; however, the preferred scale for the elderly was the VDS, regardless of gender.

The objective of this study was to verify and describe, from a gender focus, the associations between gender and specific postoperative pain variables in pediatrics. This is a cross-sectional study of 77 children between 6 and 13 years of age (M=9 years; sd=2.2 years), ASA I and II, 77.9% from low-income classes, 68.8% boys and 32.8% girls. Data were collected on the first postoperative (1st PO) day through semi-structured interviews and four measurement scales. The main baseline diseases were adenotonsillitis and fractures. Prevalence of pain on the 1st PO was 91.7% for girls and 75.5% for boys (p>0.05). No association was found between pain intensity and gender. The most used pain descriptors were it cuts and it squeezes. The preferred scale was the EFMC (with faces from a Brazilian cartoon: Monica's Gang). Pediatric pain management is still inadequate and gender may influence the pain response.

Objectives: to estimate the incidence and the risk factors for severe acute postoperative pain self-reported on the first day after hospital discharge. Methods: cohort study with 279 children from both sexes (5-12 years old), indicated for ambulatory surgery in two Brazilian hospitals. Children were assessed at the pre-surgery, immediate postoperative and first postoperative day. Faces Pain Scale-Revised and Yale Preoperative Anxiety Scale Modified were used. Severe postoperative pain was defined as score ≥6. Cox regression analyses were used. Results: the incidence of severe postoperative pain was 15.8% (95%CI:10.7%-20.4%) on the first postoperative day. Preoperative anxiety (HR=2.23; p=0.049), severe preoperative pain (HR=2.78; p=0.031) and having undergone two surgical procedures (HR=2.91; p=0.002) were associated with severe postoperative pain. Conclusions the incidence of severe postoperative pain self-reported after hospital discharge was high. Anxiety and severe preoperative pain, in addition to performing two surgical procedures at the same time were confirmed as risk factors.

Objective: To analyze the factors associated with quality of life of the older adults with chronic pain. Method: Cross-sectional study conducted with 239 older adults in outpatient care in the state of Goiás, Brazil. The World Health Organization Quality of Life–Old (WHOQOL-OLD) instrument contains six domains and was applied to assess quality of life. Simple and multiple linear regressions were used in the statistical analysis. Results: The factors associated with Sensory Abilities were age (β = - 0.52), time spent together (β = - 14.35; - 17.86; - 15.57), and pain intensity (β = - 1, 70). Autonomy was associated with depression (β = - 5.99) and chest pain (β = - 6.17). Social participation related to schooling (β = - 0.64), diabetes mellitus (β = - 8.15), depression (β = - 14.53), pain intensity (β = - 1.43), and lower limb pain (β = - 5.94). Past, present and future activities related to depression (β = - 6.94). Death and dying related to hypertension (β = - 8.40), while Intimacy to depression (β = - 5.99) and headache/face pain (β = - 3.19). Conclusion: The time experiencing chronic pain and the location of this experience, as well as depression, diabetes and systemic arterial hypertension were factors that had greater influence on the older adult’s Quality of Life domains.

Objective: To analyze the perceptions of children and adolescents about chronic postsurgical pain, experienced for three years after outpatient inguinal herniorrhaphy. Method: Descriptive, exploratory study, with a qualitative approach. Children and adolescents who reported chronic postsurgical pain were invited from previous quantitative research. The interviews with a semi-structured script were recorded, transcribed, and coded according to content analysis, thematic modality. Results: Twenty children and teenagers participated. They attributed different meanings to chronic persistent postsurgical pain, configuring a bad, uncomfortable, intermittent and limiting experience, which socially isolates, interferes with daily, school, and leisure activities. The report of pain was underestimated and neglected by the children’s and adolescents’ healthcare team, family members, teachers, and friends. Conclusion: Children and adolescents recognize postsurgical pain as persistent pain and seem to perceive that their report is underestimated and neglected by parents and teachers. Additionally, they feel responsible for the presence of pain that affects psychological and social dimensions and imposes damage and fear that leads to the return of the hernia and to death.
