刺激乳头对产后出血的影响:(附300例分析) 总被引:17,自引:0,他引:17
本文对1992年8月至1992年12月在辽宁省彰武县正常分娩、非高危妊娠的300例产妇进行产后出血的前瞻性研究。其中200例为实验组,当胎儿前肩娩出后刺激双侧乳头以增强子宫收缩;另选条件相似的100例产妇为对照,不作任何干预,对比第三产程时间及产后2小时和产后24小时的出血量。结果证明:胎儿前肩娩出后刺激乳头能减少产后出血发生率,对照组产后出血发生率为20%,刺激乳头组产后出血发生率仅为10.51%,二组差异显著,P<0.05。此方法简便易行,适于推广应用。 相似文献

OBJECTIVE: To evaluate the use of a standard pen-and-paper test versus the use of a checklist for the early identification of women at risk of postpartum depression and to investigate the experiences of nurses in using the checklist. DESIGN: A prospective cohort design using repeated measures. SETTING: The booking-in prenatal clinic at a regional hospital in Victoria, Australia, and the community-based postpartum maternal and child health service. PARTICIPANTS: 107 pregnant women over 20 years of age. MAIN MEASURES: Postpartum Depression Prediction Inventory (PDPI), Postpartum Depression Screening Scale (PDSS), Edinburgh Postnatal Depression Scale (EPDS), demographic questionnaire, and data on the outcome from the midwives and nurses. RESULTS: The PDPI identified 45% of the women at risk of depression during pregnancy and 30% postpartum. The PDSS and EPDS both identified the same 8 women (10%), who scored highly for depression at the 8-week postpartum health visit. Nurses provided 80% of the women with anticipatory guidance on postpartum depression in the prenatal period and 46% of women at the 8-week postpartum health visit. Nurse counseling or anticipatory guidance was provided for 60% of the women in the prenatal period. CONCLUSION: The PDPI was found to be a valuable checklist by many nurses involved in this research, particularly as a way of initiating open discussion with women about postpartum depression. It correlated strongly with both the PDSS and the EPDS, suggesting that it is useful as an inventory to identify women at risk of postpartum depression. 相似文献

Postpartum cerebral angiopathy (PCA) is an uncommon cause of ischemic and hemorrhagic stroke in young women. It is usually clinically benign and not relapsing. We describe a patient with nonhemorrhagic PCA who had an atypical progressive neurological deficit from bilateral hemisphere watershed ischemia despite treatment with aggressive medical therapy and intracranial balloon angioplasty. 相似文献

Revision of the postpartum depression predictors inventory 总被引:1,自引:0,他引:1

Postpartum depression has been described as a thief that steals motherhood. Early recognition is one of the major challenges with this devastating mood disorder. This article describes a revised version of the Postpartum Depression Predictors Inventory (PDPI) based on the results of an updated meta-analysis. This revised inventory consists of 13 risk factors related to postpartum depression. Guide questions for each of the 13 predictors that clinicians can use during an interview process also are included. Included among these 13 predictors in the PDPI-Revised are four new risk factors: self-esteem, marital status, socioeconomic status, and unplanned/unwanted pregnancy. Ideally, this checklist should be completed each trimester to update a pregnant woman's risk status. After a woman gives birth, the PDPI-Revised should be used to continue to monitor her risk status because she can develop postpartum depression at any time during the 1st year after childbirth. 相似文献

The effect of postpartum depression on child cognitive development and behavior: A review and critical analysis of the literature 总被引:10,自引:3,他引:7
Summary ¶The incidence of postpartum depression (PPD) in Western societies is approximately 10–15% and its cause multi-faceted. Because mothers largely constitute infants social environment and mediate their experience of the external world, it is imperative to investigate the effects of PPD on child growth and development. PsycInfo, Medline, Embase, CINAHL, ProQuest, and Health Star databases were searched with key terms for English language abstracts from 1990 onwards, and key contents were searched. There are small effects of PPD on cognitive development such as language and IQ, seen particularly among boys. Behavioral effects are variably supported, but may persist up to 5 years postpartum and beyond. However, chronic or recurrent maternal depression, rather than postpartum depression per se is likely related to later effects on the child. These adverse effects of PPD based on sex of infant are discussed.Received February 7, 2003; accepted June 15, 2003

Interpersonal psychotherapy adapted for the group setting in the treatment of postpartum depression 总被引:4,自引:0,他引:4
Klier CM Muzik M Rosenblum KL Lenz G 《The Journal of psychotherapy practice and research》2001,10(2):124-131
Interpersonal psychotherapy (IPT) has demonstrated efficacy in the individual treatment of antepartum and postpartum depression. The current investigation extends prior work by examining the efficacy of a group IPT approach for the treatment of postpartum depression. Depression scores of 17 women diagnosed with postpartum depressive disorder (DSM-IV criteria) decreased significantly from pre- to post-treatment. Follow-up assessments at 6 months revealed continuation of the treatment effect. Results indicate that IPT adapted for a group model has positive implications for the treatment of postpartum depression, demonstrating both short-term and longer-term effects in the reduction of depressive symptomatology. Study limitations include the small sample size, absence of control group, possible bias in therapist's assessments, and lack of monitoring adherence, which may have jeopardized the accuracy of the results. 相似文献

目的探讨认知行为治疗对产后抑郁症患者的功能失调性认知和抑郁症状的疗效。方法对48例产后抑郁症患者进行8周的认知行为治疗,对照组的45例产后抑郁症给予健康宣教等一般治疗,采用功能失调性态度问卷(DAS)、汉密尔顿抑郁量表(HAMD)等进行评估。结果治疗后干预组的DAS总分及脆弱性、完美化、依赖性及自主性态度等因子分均显著低于对照组(P〈0.05或0.01),且干预组治疗前后的DAS总分及脆弱性、完美化、依赖性及自主性态度等因子分也有显著性差异(P〈0.05或0.01);干预组总有效率为89.6%,对照组总有效率为53.3%(t=6.37,P〈0.01)。治疗后两组的HAMD总分有极显著性差异(t=6.37,P〈0.01)。结论认知行为治疗能显著改善产后抑郁症的功能失调性认知,对产后抑郁有较好的疗效。 相似文献
