目的：探讨低危初产妇与健康足月儿产后第1小时进行皮肤接触的情感体验，为产后优质护理提供依据。方法采用质性研究方法对12例进行母婴皮肤接触的产妇在产后第2天进行深度访谈。结果皮肤接触能缓解产妇伤口缝合时的疼痛感、增加母婴安全感和亲情感、缓解产妇在产房观察时的孤独感、唤起产妇做母亲的责任感，坚定母乳喂养的决心，经历皮肤接触新生儿能更好地衔接乳头进行吸吮，产妇乳汁能满足新生儿需求；然而少部分产妇可能因为知识缺乏而担心该方式对新生儿有影响。结论为孕产妇提供皮肤接触健康教育内容和形式应丰富多彩；护理人员需进行相关培训和知识更新，并进行有关皮肤接触的护理科研，推动临床实践，使皮肤接触得以推广。

Objective To study the trends of urogenital tract mycoplasma infection and drug sensitivity in Shanghai district.Methods Slats culture was used for culturing and drug sensitivity test for genitourinary tract infection with Ureaplasma urealyticum(UU) and Mycoplasma hominis(MH).Results Mycoplasma was positive in 2 640 of 3 464 specimens,the positive rate was 40.8%;positive rates in male and female were 26.7% and 49.3%,respectively.Infection rate in female was higher than that in male,and infection occurred primarily in 21-40 years of age.The positivity rates of UU,MH and UU mixed with MH were 37.5%,<0.1% and 3.3%,respectively.Drug-sensitivity test showed that mycoplasma was sensitive to doxycycline,josamycin and minocycline.UU was highly resistant to norfloxacin,with a resistance rate of 64.4%;while UU mixed with MH infection was most resistant to erythromycin,roxithromycin,clarithromycin and azithromycin,the resistant rate was 96.7% and above.Multidrug resistance was seen in 32.7% of the specimens.Conclusins Urogenital tract mycoplasma infection results mainly from UU and UU mixed with MH,mostly occurred in young sexually active period.Resistance to conventional antibiotics is not uncommon,the rational use of antibiotics should be based on the results of drug sensitivity test.

随着镇痛泵被广泛应用于剖宫产术后患者的镇痛,有效地解决了产妇术后的疼痛问题,提高了患者生活质量,促进了产妇机体的恢复和母乳喂养.但在缓解患者疼痛的同时,镇痛泵的应用也导致了留置尿管时间延长,甚至使产妇易发生尿潴留[1].为了更好地解决这一问题,我们对140例患者进行了临床观察,对产后140例留置导尿管患者拔管方法作了对比观察.

Objective To explore the clinical manifestation and electroneurophysiological findings in cubital tunnel syndrome(CubTS),and to improve our understanding of CubTS.Methods The clinical manifestation and electroneurophysiological findings of 37 cases of CubTS were retrospectively analyzed.Electroneurophysiological data of symptomatic upper limbs were compared with those of asymptomatic counterpart upper limbs.Results The most complaint of patients was paresthesia in the areas supplied by the ulnar nerves.46% of the patients with CubTS were caused by flexion of the elbow for prolonged periods.The primary electroneurophysiological findings were the abnormity of the motor conduction velocity(MCV) in across elbow segment of the ulnar nerve,the amplitude of sensory nerve action potential(SNAP) of the little finger to wrist and the amplitude of nerve action potential(NAP) in the ulnar nerve of the wrist to elbow,as(33.57±12.16) m/s,(5.91±5.88) μV,(4.45±5.34) μV,respectively.The difference between symptomatic upper limbs and their asymptomatic counterpart upper limbs was significant.Conclusion Electroneurophysiological detection is helpful for diagnosing CubTS in early stage.The dominating cause is flexion of the elbow for prolonged periods.

腕管综合征(CTS)是正中神经于腕管内受压而引起神经功能障碍,是常见嵌压性周围神经病,早期治疗预后良好.现将我院2006年3月～2007年6月收治的78例CTS患者的临床及电生理资料回顾性分析如下.
