Association of Multimodal Pain Control with Patient-Reported Outcomes in Children Undergoing Surgery
《Journal of pediatric surgery》2023,58(6):1206-1212
IntroductionOur aim was to describe practices in multimodal pain management at US children's hospitals and evaluate the association between non-opioid pain management strategies and pediatric patient-reported outcomes (PROs).MethodsData were collected as part of the 18-hospital ENhanced Recovery In CHildren Undergoing Surgery (ENRICH-US) clinical trial. Non-opioid pain management strategies included use of preoperative and postoperative non-opioid analgesics, regional anesthetic blocks, and a biobehavioral intervention. PROs included perioperative nervousness, pain-related functional disability, health-related quality of life (HRQoL). Associations were analyzed using multinomial logistic regression models.ResultsAmong 186 patients, 62 (33%) received preoperative analgesics, 186 (100%) postoperative analgesics, 81 (44%) regional anesthetic block, and 135 (73%) used a biobehavioral intervention. Patients were less likely to report worsened as compared to stable nervousness following regional anesthetic block (relative risk ratio [RRR]:0.31, 95% confidence interval [CI]:0.11–0.85), use of a biobehavioral technique (RRR:0.26, 95% CI:0.10–0.70), and both in combination (RRR:0.08, 95% CI:0.02–0.34). There were no associations of non-opioid pain control modalities with pain-related functional disability or HRQoL.ConclusionUse of postoperative non-opioid analgesics have been largely adopted, while preoperative non-opioid analgesics and regional anesthetic blocks are used less frequently. Regional anesthetic blocks and biobehavioral interventions may mitigate postoperative nervousness in children.Level of evidenceIII. 相似文献

This article explores the dynamics between fat shaming, neoliberalism, ideological constructions of health and the ‘obesity epidemic’ within the UK, using the UK Government’s recent Tackling Obesity campaign in response to Covid-19 as an illustration. We draw attention to how fat shaming as a practice that encourages open disdain for those living with excess weight operates as a moralising tool to regulate and manage those who are viewed as ‘bad’ citizens. In doing so, we begin by outlining how the ideological underpinnings of ‘health’ have been transformed under neoliberalism. We then consider the problematic use of fat shaming discourses that are often used as tools to promote ‘healthy’ lifestyle choices by those who view it as not only an acceptable way of communicating the health risks associated with obesity but also a productive way of motivating people with obesity to lose weight. Drawing on Graham Scambler’s theoretical framework regarding shame and blame (2020), we discuss how ‘heaping blame on shame’ has become a ‘wilful political strategy’ under neoliberalism, particularly as it relates to individuals with obesity, and how the Tackling Obesity campaign leverages concerns around ‘choices’ and ‘costs’ as a means through which to encourage normative models of self-care and self-discipline. 相似文献

ObjectiveTo compare levels of postoperative oxycodone use and incisional pain between two randomized groups—an intervention and a control.DesignMixed-methods design; quantitative data achieved via a randomized controlled trial, with qualitative data collected on binder use. The primary variable was oxycodone (in milligrams) required during the first 48 hours after birth, and the secondary variable was incisional pain levels measured on Postoperative Days 1 and 2.SettingAcute-care community hospital in Wheat Ridge, Colorado, and an acute care urban hospital in Denver, Colorado.ParticipantsA total of 220 individuals in the postpartum period after having cesarean birth.Interventions/MeasurementsParticipants were randomized to the intervention group (binder) or the control group (no binder). Data were collected on opioid usage for the first 48 hours. Participants in both groups were asked to rate their incisional pain on Postoperative Day 1 (24 hours after birth) and Postoperative Day 2 (48 hours after birth). Participants in the binder group were also asked to provide feedback on their experience wearing the binder.ResultsA total of 196 participants completed the study. The overall amount of oxycodone taken by individuals in the binder group was lower than that in the control group, but the difference was not statistically significant (p = .10). Pain scores in the binder group were significantly lower on Day 2 compared with the control group (p = .002). The majority of individuals in the binder group provided positive feedback about their experience wearing the binder.ConclusionIndividuals routinely receive medications to assist with pain management postoperatively. Because of growing concerns related to the nation’s opioid addiction crisis, there is interest in using multimodal treatments to achieve adequate pain control for individuals postoperatively. Abdominal binders are a low-cost intervention to assist with pain management and, given the results of this study, seem like a reasonable option to consider. 相似文献

The aim of this study was to analyse the effect of body mass index (BMI), both low and high values, on the perioperative complication rate in patients with oral squamous cell carcinoma (OSCC). The medical records of 259 patients operated between 2014 and 2017 for OSCC were reviewed. Univariate and multivariate analyses were performed. Sixty of the 259 patients developed 87 complications. Low or high BMI was not associated with the perioperative complication rate. A longer operating time and increased blood loss were associated with a higher perioperative complication rate and higher Clavien–Dindo grade. Low BMI, American Society of Anesthesiologists score 2 and 3, a longer operating time, and increased blood loss were associated with a longer hospital stay. Low BMI was associated with a longer hospital stay. Neither low nor high BMI was associated with the perioperative complication rate. A longer operating time and increased blood loss were associated with a higher perioperative complication rate and higher Clavien–Dindo grade. 相似文献

AbstractThe study examines Parental Feeding Practices (PFP) in relation to adherence to the Mediterranean Diet (MD) and children’s weight status. It’s a cross-sectional study of 402 parents (68.4% mothers), with children aged 2–12 years. Parents completed the Comprehensive Parental Feeding Questionnaire and the Mediterranean Diet Quality Index for children and adolescents (KIDMED), evaluating children’s adherence to the MD. Logistic regression showed that in children aged 2–<6 years, “emotion regulation/food as reward” and “pressure” decrease MD adherence (OR?=?0.186, p?<?0.0001 and OR?=?0.496, p?=?0.004), and “monitoring” decrease excess body weight (OR?=?0.284, p?=?0.009). In older children (6–12 years), “healthy eating guidance” and “monitoring” increase MD adherence (OR?=?3.262, p?=?0.001 and OR?=?3.147, p?<?0.0001), “child control” decreases MD adherence (OR?=?0.587, p?=?0.049), “pressure” decrease excess body weight (OR?=?0.495, p?<?0.0001) and “restriction” increase excess body weight (OR?=?1.784, p?=?0.015). “Healthy eating guidance” and “monitoring” seem to be the best PFP employed, in terms of children’s MD adherence and weight status. 相似文献

ObjectiveThis study aimed to compare how children with overweight or obesity and their parents perceive the obesity-related terms used by healthcare professionals and investigate the factors associated with these perceptions.MethodsChildren and adolescents aged 8–16 years with overweight or obesity (n = 192) and their parents participated in the cross-sectional study by responding to a 5-point Likert-scale questionnaire on 10 obesity-related terms, including “chubby,” “weight problem,” “weight,” “overweight,” “BMI,” “obese,” “heavy,” “fleshy,” “fat,” and “severely obese.”ResultsFor both children and parents, “chubby” was the most desirable term (mean ± standard deviation: 3.50 ± 1.12 and 2.95 ± 0.83, respectively), and “severely obese” was the least acceptable term (2.83 ± 1.17 and 2.02 ± 1.02, respectively). Although the parents preferred all the terms less than the children did (p < 0.001), “weight problem” was considered most motivating for a child to lose weight (3.93 ± 0.94). Among children, older age and a larger self-perceived body size were associated with a more positive response towards obesity-related terms, whereas having internalized or externalized problems were negatively associated with these terms. Parents with a history of cardiovascular disease considered “severely obese” (β = ?0.419, [95% CI: ?0.739, ?0.099]) and “fat” (β = ?0.457, [95% CI: ?0.750, ?0.164]) less desirable.ConclusionsChildren and adolescents had a higher preference for obesity-related terms than their parents and preferred that healthcare professionals use euphemistic terms such as “chubby,” or neutral terms such as “weight problem.” Children with larger self-perceived body sizes or older age had a higher preference for obesity-related words. The terms used by healthcare professionals to describe excess weight must be motivating and respectful for all family members participating in the treatment. 相似文献

In the United States, renal cell carcinoma (RCC) incidence and the prevalence of obesity, an established risk factor for RCC, have been increasing for several decades. RCC is more common among older individuals. We sought to quantify the contribution of excess adiposity to the rising incidence of RCC among individuals 60 years or older. National Institutes of Health-American Association of Retired Persons Diet and Health Study data (n = 453 859 participants, enrolled in 1995-1996, age at enrollment 50-71 years) were used to estimate multivariable-adjusted hazard ratios (HRs) for RCC across body mass index categories and HRs associated with smoking. Population attributable fractions (PAFs) were calculated using estimated HRs and annual overweight/obesity prevalence from the National Health Interview Survey (1985-2008). PAF estimates were combined with RCC incidence from Surveillance, Epidemiology and End Results-13 to calculate annual percent changes in RCC incidence attributable (and unrelated) to overweight/obesity. We found that between 1995 and 2018, among individuals aged 60 years and older, PAF for overweight/obesity increased from 18% to 29% for all RCCs. In comparison, the PAF for smoking declined from 12% to 9%. RCC incidence increased 1.8% per year (95% confidence interval [CI] 1.5%-2.1%) overall, while RCC incidence attributable to overweight/obesity increased 3.8% per year (95%CI 3.5%-4.2%) and RCC incidence unrelated to overweight/obesity increased 1.2% per year (95% CI 0.9%-1.4%). In conclusion, overweight/obesity appears to have contributed importantly to the rising incidence of RCC in the United States since the mid-1990s. Public health interventions focused on reducing overweight and obesity could help substantially in curbing this trend. 相似文献
