利多卡因凝胶在手术室麻醉诱导后留置尿管中的应用

分析手术室麻醉诱导后留置尿管产生尿路疼痛等不良反应的原因,探讨利多卡因凝胶在克服上述反应方面的作用及其他预防措施。采用方便取样将70例留置尿管的患者分为试验组和对照组,麻醉诱导后试验组在尿管上涂抹利多卡因凝胶（0．5ml／cm）后再按常规操作插管;对照组以石蜡油为润滑剂按常规操作留置尿管。比较两组患者心率、血压情况及躁动、疼痛评分。结果提示麻醉诱导后留置尿管可以有效减轻患者清醒状态下置管引起的尿路疼痛等问题,但不能避免患者苏醒期出现上述反应;使用利多卡因凝胶可有效预防患者苏醒期出现的尿路疼痛及其它不良反应,增加患者的舒适度。     

子宫内膜异位症引起的盆腔疼痛的诊断和治疗

子宫内膜异位症(endometriosis,EMT)是妇科最常见的疾病之一,且发病率呈逐年上升趋势,盆腔疼痛是它常见的症状之一,其发病机制尚未明确,易复发,成为妇科研究的热点和难点。随着对EMT引起盆腔疼痛的发病机理的不断认识,其诊治也相应得到完善和发展。本文从哲学的角度以认识和实践等观点对EMT引起盆腔疼痛的诊断和治疗进展进行综述,以助于临床诊治。     

Differences in High and Low Anxiety Sensitive Women's Responses to a Laboratory‐Based Cold Pressor Task

Anxiety sensitivity (AS) has been linked to a variety of disabling chronic health conditions, including pain‐related conditions. A recent study has found that healthy women with high AS reported significantly higher levels of sensory and affective pain on an experimental cold pressor task compared to women with low AS. However, this study found no differences between AS groups for pain tolerance or pain threshold. In the present study, which was designed to replicate and extend these findings, 90 undergraduate university women were selected for inclusion in 1 of 2 AS groups (high or low) based on their screening scores on a 16‐item measure of AS. Participants were tested individually on a lab‐based cold pressor task using a variety of self‐report and observer‐measured variables. Data analyses revealed that, as expected, the high AS participants reported significantly more fear in response to the cold pressor on a relevant item of the McGill Pain Questionnaire – Short Form (SF‐MPQ) than did the low AS participants. Also as expected, the high AS participants reported more pain in response to the cold pressor on the Present Pain Index (PPI) of the SF‐MPQ than did the low AS participants. High AS participants did not differ from low AS participants on other aspects of the cold pressor response (e.g. pain threshold, pain tolerance, pain recovery). These results support the role of pain‐related fear as a mediating variable between AS and increased perceived pain intensity.     

Explicit and implicit attitudes towards food and physical activity in childhood obesity

This study investigated differences in the explicit and implicit attitudes towards food and physical activities between children with obesity (n=38) and a matched control group (n=38). The implicit attitude was assessed using the Extrinsic Affective Simon Task (EAST; J. Exp. Psychol. (50) (2003) 77), a modified version of the Implicit Association Test (IAT; J. Personality Social Psychol. (74) (1999) 1464). It was expected that both groups would report a positive explicit attitude towards healthy food and intense physical activities, and a negative explicit attitude towards unhealthy food and sedentary activities. Of particular interest was the hypothesis that children with obesity would have a more positive implicit attitude towards unhealthy food and sedentary activities than the control group. Results revealed no differences between groups in the explicit attitude towards food and physical activity. Children and adolescents with obesity had a more pronounced positive implicit attitude towards food in general. The relevance of these findings in terms of prevention, treatment and further research is discussed.     

Using self-determination theory to promote adolescent girls' physical activity: Exploring the theoretical fidelity of the Bristol Girls Dance Project

ObjectivesTo report the theory-based process evaluation of the Bristol Girls' Dance Project, a cluster-randomised controlled trial to increase adolescent girls' physical activity.DesignA mixed-method process evaluation of the intervention's self-determination theory components comprising lesson observations, post-intervention interviews and focus groups.MethodFour intervention dance lessons per dance instructor were observed, audio recorded and rated to estimate the use of need-supportive teaching strategies. Intervention participants (n = 281) reported their dance instructors' provision of autonomy-support. Semi-structured interviews with the dance instructors (n = 10) explored fidelity to the theory and focus groups were conducted with participants (n = 59) in each school to explore their receipt of the intervention and views on the dance instructors' motivating style.ResultsAlthough instructors accepted the theory-based approach, intervention fidelity was variable. Relatedness support was the most commonly observed need-supportive teaching behaviour, provision of structure was moderate and autonomy-support was comparatively low. The qualitative findings identified how instructors supported competence and developed trusting relationships with participants. Fidelity was challenged where autonomy provision was limited to option choices rather than input into the pace or direction of lessons and where controlling teaching styles were adopted, often to manage disruptive behaviour.ConclusionThe successes and challenges to achieving theoretical fidelity in the Bristol Girls' Dance Project may help explain the intervention effects and can more broadly inform the design of theory-based complex interventions aimed at increasing young people's physical activity in after-school settings.     

多模式镇痛在幻肢痛预防中的临床研究

为探讨多模式镇痛预防截肢后幻肢痛的临床效果。选择50例下肢截肢患者,随机分为2组,试验组（Ⅰ组）和对照组（Ⅱ组）,观察患者疼痛评分,患者自控镇痛按压次数,使用其他镇痛药物的情况,记录所有的不良反应及幻肢痛发生率。结果显示,镇痛评分,Ⅱ组高于Ⅰ组（P〈0．01）;PCA按压次数,Ⅱ组多于Ⅰ组（P〈0．01）;不良反应发生率Ⅱ组高于Ⅰ组（P〈0．01）;Ⅱ组幻肢痛发生率明显高于Ⅰ组（P〈0．01）。采取多模式镇痛预防幻肢痛是安全有效的。     

Optimism and pessimism as predictors of physical and psychological health among grandmothers raising their grandchildren

This study examines the role of personality in predicting psychological and physical health among grandmothers who are coping with a non-normative non-traumatic stressor, i.e. serving as primary caregivers for their grandchildren. Using the Life Orientation Test-Revised (LOT-R), a measure of personality disposition, we examine the contributions of both optimism and pessimism to health outcomes. ANOVAs and regression analyses of the LOT-R and self reports of health in 67 African American and Latino grandmothers revealed psychological (obsessive compulsive symptoms, depression, hostility) and physical (sleep disorder, hypertension) health outcomes are differentially predicted by optimism and pessimism among older and younger age-groups of grandmothers. Implications for grandmothers’ response to caregiving stress and for future studies of personality’s relation to health are discussed.
