目的 观察腹腔镜胆囊切除患者术前焦虑对术后疼痛及麻醉后复苏的影响. 方法 选择82例择期行腹腔镜胆囊切除术患者,术前依照贝克焦虑量表(Beck's anxiety inventory,BAI)评测结果将患者分为两组:正常组(50例)和焦虑组(32例).焦虑组患者伴有焦虑症状,正常组患者无焦虑症状.观察记录手术时间、麻醉时间、改良Aldrete评分(modified Aldrete score,MAS)达9分的时间和副作用.术后疼痛控制采用芬太尼患者自控静脉镇痛的方法,记录患者术后VAS评分、芬太尼用量和补充镇痛药物使用情况. 结果 患者术前焦虑症发生率为39%.焦虑组患者改良Aldrete评分达9分的时间为(6.3± 1.5)s,明显长于正常组(5.0±1.4)s(P<0.05),术后副作用发生率也高于正常组(P<0.05).术后4、8、12h焦虑组患者VAS评分高于正常组[4 h:(3.5±0.7)分比(2.6±1.0)分;8 h:(3.3±0.9)分比(2.2±0.8)分;12 h:(3.1±0.5)分比(2.4±0.6)分](P<0.05).患者术前BAI评分与术后8、12 h VAS评分呈正相关(8 h:r=0.422;12 h:r=0.526)(P<0.05).焦虑组患者术后芬太尼用量和追加氯诺昔康补充镇痛的需求均高于正常组(P<0.05). 结论 术前焦虑对麻醉后复苏以及术后镇痛有着负面影响,对于焦虑患者需增加术后镇痛力度才能达到良好的止痛效果. 相似文献

BackgroundWomen with breast cancer often attribute their health problems as side effects caused by oncological treatments. The aim of the study was to examine and compare self-reported health complaints (SHC) in postmenopausal patients with breast cancer to healthy controls.MethodWomen with breast cancer (N = 196) filled in 5 questionnaires 1–2 years after surgery; SHC Inventory, Functional Assessment of Cancer Therapy-Endocrine Subscale (FACT-ES), Fatigue – Functional Assessment of Cancer Therapy-Fatigue subscale (FACIT-F), Fatigue Visual Analog Scale (Fatigue VAS), and Hospital Anxiety and Depression Scale (HADS). Controls comprised 101 blood donors who reported on the questionnaires except for HADS. Bonferroni adjustment and p < 0.0017 was considered statistically significant for SHC Inventory, p < 0.05 for the remaining questionnaires.ResultsThe patients, mean age 58.0 (SD 9.5), reported significantly more self-reported health complaints, whereof 6 of 29 complaints were significantly elevated compared to the controls, mean age 57.0 (SD 5.8) (p < 0.001). HADS scores in patients fell into normal range, mean 6.3 (SD 5.7). A subgroup of 48 patients experienced more frequent and severe symptoms in all the questionnaires compared to the remaining 148 patients, and the 101 controls. Among the patients, fatigue, anxiety and depression explained 49% of the total variance in self-reported health complaints (p ≤ 0.001).ConclusionMost women with breast cancer (76%) reported health complaints equal to the healthy controls. Fatigue, anxiety and depression, not oncological treatments, were significant predictors for the complaints. 相似文献

BodyBalance is a popular mind–body program practised at numerous leisure centres throughout the western world that makes many unsubstantiated claims as to the benefits of participation. This study examines physiological and psychological responses in adults, aged (mean ± S.D.) 43.9 ± 10.9 years, to a 12-week ‘BodyBalance’ exercise program. An exercise intervention group (n = 17) undertook three 1-h classes, each week for 12 consecutive weeks while the control group (n = 17) attended three 90-min ‘health lectures’. ANCOVA demonstrated significant differences between the control and exercise groups in body mass, skinfold measures, total girth circumference from six sites, maximal isometric back strength, five measures of flexibility and state anxiety. Post-hoc tests on the experimental group data showed body fat decreased significantly by 1.10 ± 1.02% (t = 4.44; P < 0.01), girth by 4.40 ± 5.80 cm (t = 3.13; P < 0.01) and back strength increased by 17.12 ± 15.39 kgf (t = −4.59; P < 0.01). Flexibility was also significantly enhanced with performance of the modified sit-and-reach test increasing by 5.90 ± 2.56 cm (t = −9.50; P < 0.01), hip flexion by 9.84 ± 8.41° (t = −4.82; P < 0.01), hip extension by 7.65 ± 4.48° (t = −7.04; P < 0.01), hip abduction by 10.00 ± 4.91° (t = −8.40; P < 0.01) and lateral trunk flexion by 3.06 ± 5.72° (t = −2.21; P < 0.05). Finally, state-anxiety (STAI) was significantly reduced intra-class at weeks 1, 6 and 12 by 9.24 ± 9.46 (t = 4.02; P < 0.01), 6.59 ± 6.26 (t = 4.34; P < 0.01) and 7.18 ± 5.50 (t = 5.38; P < 0.01), respectively. The findings of this study suggest mind–body exercise programs like BodyBalance could significantly benefit state-anxiety as well as strength, flexibility, and anthropometry around the trunk. 相似文献

Surgery is a stressful experience. Many minor interventions have been shown to cause considerable anxiety in patients, but
whether arthroscopy leads to such anxiety is not well-known. Methods for lowering perioperative anxiety have been sought and
listening to music or watching a movie have been recommended. The method of permitting patients to watch their own endoscopy
has been studied infrequently. Our aim in this study was to find out the effect of watching simultaneous arthroscopic views
on postoperative anxiety. A total of 63 patients were randomly divided into two groups: those watching their own arthroscopy
formed group W, while patients that were only verbally informed formed group NW. The mean age of patients in both groups were
33 and 34, respectively. Meniscal surgery was the most commonly performed procedure (49/63 patients). The patients filled
in state scale of State-trait anxiety inventory (STAI) forms and the study questionnaire (SQ) prepared for this study, just
before and after the arthroscopy. Group W had significantly lower postoperative scores of STAI-S, whole questionnaire (Q-score) and all but one of individual statements in SQ. Having a previous operation history did not affect STAI scores. Age
and level of education was not correlated with any of the studied parameters either. The ratio of patients that were pleased
with the arthroscopy experience in group W and NW were 94 and 63%, respectively. Watching live arthroscopic views has led
to a significant decrease in postoperative anxiety and worries about the surgery and the postoperative period, while increasing
overall understanding and satisfaction of the patient. 相似文献

目的:探讨不同分娩方式产妇焦虑抑郁情绪差异,分析其发生状况以及可能的影响因素。方法根据分娩方式不同将2013年10月至2014年5月在成都市某医院产科及某区妇幼保健院分娩的380例产妇分为剖宫产组和顺产组,采用自编一般信息问卷、抑郁自评量表和焦虑自评量表分别对产妇进行测评。结果剖宫产组与顺产组焦虑情绪在产后前3 d 组间比较差异有统计学意义(t 1=-3.292、t 2=-2.316、t 3=-2.666;P 均<0.05);经多元 logistic 回归分析筛选出剖宫产组的焦虑影响因素为泌乳量,顺产组产妇焦虑的影响因素为产后天数、产后下床活动时间及泌乳量;剖宫产产妇产后前3 d 抑郁情绪逐渐减轻但此后递增,顺产产妇5 d 内抑郁情绪逐渐减轻。运用多元 logistic 回归分析,筛选出剖宫产组抑郁情绪的影响因素为泌乳量、产后自行排尿时间,顺产组抑郁情绪的影响因素为泌乳量、产后天数。结论不同分娩方式的产妇均普遍存在产后焦虑抑郁情绪,关注产妇心理健康,适时进行心理干预,对产妇的产后恢复以及新生儿的健康成长具有重要意义。 相似文献
