目的 探究全程导乐助产护理联合心理护理干预对分娩产妇焦虑抑郁评分、自然分娩率及新生儿窒息发生率的影响。
方法 以南京医科大学附属无锡妇幼保健院于2018年1月至2019年1月收治的96例产妇为研究对象,随机分为两组各48例。对照组应用常规护理方法助产,观察组采用全程导乐助产护理联合心理护理,分析并比较两组产妇的疼痛程度、焦虑抑郁情绪以及产后母婴结局,如自然分娩率、新生儿窒息、胎儿窘迫以及出血率等。
结果 两组产妇的SAS和SDS评分在生产后都有明显降低(P<0.05),其中观察组产妇两项评分低于对照组(P<0.05);观察组产妇的疼痛程度多分布于1级(64.58%),而对照组多分布于2和3级(47.90%、27.10%),两组相比,观察组疼痛程度明显轻于对照组(P<0.05);另外,对照组患者的自然分娩、胎儿窘迫、新生儿窒息、产后出血的发生病例数分别为24(70.8%)、6(12.5%)、5(10.4%)、4(8.3%)例,观察组分别为42(87.5%)、1(2.1%)、0例,观察组各项发生率均明显低于对照组(P<0.05)。
结论 将全程导乐助产护理联合心理护理应用于自然分娩过程,可显著改善产妇负面情绪,降低疼痛程度,促进母婴良好结局,具有临床应用价值。 相似文献

While control-related cognitions have often been implicated in discussions of Obsessive Compulsive Disorder (OCD), empirical
investigations of the relationship between control-constructs and OCD symptoms have been relatively limited. In this article
it was hypothesized that OCD symptoms may be linked with a higher desire to control (DC), but a lower sense of control (SC)
over the self and environment, leading to motivation for compulsive symptoms. This hypothesis was investigated in an analogue
population, using regression analyses controlling for depression and anxiety. Consistent with predictions, it was found that
higher levels of DC and lower levels of SC were associated with higher levels of OCD-related beliefs and symptoms. While control
cognitions were linked with the OCD-related beliefs of perfectionism and the over-estimation of threat, they did not relate
to cognitions concerning the importance of/need to control thoughts. With respect to specific OCD-symptoms, control cognitions
were most strongly related to contamination obsessions/washing compulsions. Implications for theory and treatment are discussed.

ObjectiveComprehensive tumor genomic profiling (CTGP) is increasingly used to personalize treatments, providing hope, but potentially disappointment, for patients. We explored psychological outcomes in patients with advanced, incurable cancer, after receiving CTGP results.MethodsParticipants with advanced, incurable cancer (n = 560, mean age 56, 43% university educated) in this longitudinal substudy of the Molecular Screening and Therapeutics Program (MoST), completed questionnaires before and after receiving CGP results. MoST participants, recruited from Australian oncology clinics, undergo CTGP, and if there are actionable findings, are offered treatment in a related therapeutic trial if available.ResultsPatients who received actionable results, (n = 356, 64%) had lower gene-related distress (MICRA) (p < 0.001) and Impact of Events scores (p = 0.039) than patients with non-actionable results. Those with actionable results offered ensured access to tailored treatment (n = 151) reported lower anxiety (p = 0.002) and depressive symptoms (p = 0.01) and greater hope (p = 0.002) than those not offered. Positive attitudes towards uncertainty and higher self-efficacy for coping with results were associated with lower psychological distress and uncertainty, and higher hope and satisfaction with the decision to have CTGP (ps=0.001–0.047). Those with higher knowledge reported greater anxiety (p = 0.034).ConclusionReceiving a non-actionable CTGP result, or an actionable result without ensured access to treatment, may cause increased distress in advanced cancer patients. Coping style was also associated with distress.Practice implicationsPre-testing assessment and counseling addressing attitudes toward uncertainty and self-efficacy, and post-CTGP result support for patients receiving a non-actionable result or who receive an actionable results without ensured access to treatment, may benefit patients. 相似文献

Assessment of peri-operative quality of life in patients undergoing surgery for gastrointestinal cancer 总被引:3,自引:0,他引:3
Toshiko?MatsushitaEmail author Eisuke?Matsushima Michio?Maruyama 《Supportive care in cancer》2004,12(5):319-325
The purpose of this study was to assess the pre- and postoperative quality of life (QOL) of patients with gastrointestinal cancer and to investigate the relationship between QOL and various psychological and clinical factors. Eighty-five patients who underwent surgery for gastrointestinal cancer and 26 control patients undergoing surgery for digestive diseases other than cancer were interviewed. Two tests were administered to assess QOL and psychological status respectively: the Japanese-language version of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and the Japanese-language version of the Hospital Anxiety and Depression Scale (HADS). Each test was administered before surgery, before discharge, and 6 months after discharge. Gastrointestinal tumors were localized to the stomach, colon, or rectum in 88% of cases and classified as advanced stage or early stage according to staging protocols. Changes in EORTC QLQ-C30 subscale scores over time were compared among advanced stage, early stage, and control patients. All groups showed significant changes in subscale scores of QOL; the scores of the advanced-stage group indicated worse QOL than the early-stage and control groups in a lot of areas. The physical function (PF2) QOL subscore was influenced by diagnosis, postoperative complications, medical equipment at discharge, and the length of admission and negatively correlated with depression and anxiety. These results suggest that QOL in gastrointestinal cancer patients is variable over time and is influenced by various clinical factors. Therefore, consideration of these clinical factors is paramount to the optimal care of gastrointestinal cancer patients. 相似文献

ObjectivesThis study aims to investigate the environmental and individual factors contributing to male nurses' psychological well-being and to explore the psychological mechanisms that may explain the links between nurses' practice environment and work engagement, thereby presenting the implications for nurse managers.MethodsA total of 161 male nurses from three tertiary first-class hospitals in Changsha City in China participated in the study. We collected the data using the Practice Environment Scale of the Nursing Work Index, the Psychological Capital Questionnaire, and the Utrecht Work Engagement Scale.ResultsScores of male nurses' practice environment (2.88 ± 0.31), psychological capital (4.42 ± 0.62), and work engagement (3.17 ± 1.39) were all above the midpoint; however, the subscales “the nursing staffing and resources adequacy” (2.72 ± 0.48), “hope” (4.33 ± 0.72), and “dedication” (2.96 ± 1.61)scored lowest. Nurses' practice environment and psychological capital positively predicted nurses' work engagement; psychological capital fully mediated the influence of nurses' practice environment on work engagement.ConclusionsCreating a supportive nursing practice environment can increase male nurses' work engagement by developing their psychological capital. Nurse managers can then provide reasonable workload and pathways for male nurses to achieve goals, thereby fostering their hope. 相似文献
