A questionnaire survey of career choices was carried out among 112 medical graduates, after one year's internship (group I), during their National Youth Corps programme in Kaduna, Lagos, Cross River and Oyo states of Nigeria, and 365 final-year medical undergraduates (group 2) in the colleges of medicine in the corresponding states. A total of 13% in group I and 40% in group 2 were undecided as regards their first choice. Obstetrics and gynaecology was the most popular first choice in both groups. General practice ranked fifth among group I, but displaced surgery to rank second among group 2. The differences were statistically significant. A total of 41% of group I and 46% of group 2 preferred to work in a teaching hospital, reflecting the high preference for surgical specialties. Twenty-six per cent and 33.7% of respondents in groups 1 and 2 respectively wished to own their own practice or work in the private sector. General practice is a new specialty and its growth is supported by a national postgraduate training programme. A shift towards general practice is seen compared with previous studies of career preference among Nigerian medical graduates and students. This may be due to a changing balance of supply and demand in the medical work-force, or a better assessment of the nation's health problems and manpower needs.  相似文献

患者自控镇痛在妇产科疾病介入治疗中的应用   总被引:1,自引:0,他引:1  
妇产科疾病介入治疗多采用子宫动脉栓塞(UAE),UAE后即时疼痛发生率为90%~100%,术后疼痛发生率为80%~90%,疼痛可以采用硬膜外患者自控镇痛(patient controlled epidural analgesia,PCEA)治疗。UAE围介入治疗期采用PCEA法镇痛明显优于传统用药法,其间镇痛效果好,不良反应少,能消除或减轻患者的痛苦,提高康复质量;PCEA配方中加入氟哌利多(0.005%)可以减少恶心呕吐不良反应的发生率。  相似文献

OBJECTIVE: To assess the improvement of obstetric and gynecologic training brought about by peer influence in Europe. METHODS: In 1996, the European Board and College of Obstetrics and Gynecology (EBCOG) initiated a visiting process by international and local peers to improve training and decrease differences in health care standards. RESULTS: A large number of visits of obstetrics and gynecology departments have been conducted across Europe at teaching hospitals by the Hospital Visiting Committee. Compliance with the structured approach of the visiting policy and problems met during these visits are reported. CONCLUSION: The program focuses on the continuous improvement of the competencies of all persons trained in the obstetrics and gynecology departments of teaching hospitals throughout Europe. It also increases the understanding of diversity in training methods and can gradually lead to the convergence of training and health care standards in Europe.  相似文献

Robotic surgical platforms were first developed with telesurgery in mind. Conceptualized by NASA and the military to provide surgical expertise to remote locations, some telesurgical success has been documented, but progress has been held back by communication bandwidth limitations. Telepresence surgery, where the surgeon is in proximity to the patient but is provided with an ergonomic console equipped with three-dimensional vision and autonomous control of wristed laparoscopic surgical instruments and energy sources, has shown efficacy first in cardiac and then urologic cancer surgery. Interest is currently focused on the application of this technology in the field of gynecology, with techniques being described to perform simple hysterectomy, myomectomy, tubal anastomosis, and pelvic reconstruction procedures. This article will review the application of robotic- and computer-assisted surgery in the specialty of gynecologic oncology.  相似文献

BackgroundLimited data exist on complications following hysterectomy among women with intellectual and developmental disabilities (IDD).ObjectiveThe objective was to assess the frequencies of postoperative complications in women with IDD following hysterectomy.MethodsThe National Inpatient Sample from 2014 to 2017 was queried using codes from the International Classification of Disease 9th and 10th revisions to identify women over 15 years of age with a diagnosis of an IDD undergoing hysterectomy. Comparisons were made to women without IDD undergoing the same procedure. Logistic regression analysis was performed to examine between group differences in the frequency of clinical post-surgical complications while adjusting for potential confounding variables.ResultsOf eligible women undergoing hysterectomy, 1,370 were identified as having IDD and 624,700 did not. Compared to controls, women with IDD were significantly younger (45 vs. 50 years, p < 0.001). Women with IDD were also more likely to have had governmental health insurance (83% vs. 34%, p < 0.001), an open hysterectomy approach (78% vs. 69%, p = 0.002), and longer hospital stays (4 vs. 3 days, p < 0.001). After adjusting for potential confounders, women with IDD had greater odds of postoperative urinary complications (OR 3.74, 95% CI 1.18–11.83) and complications related to decubitus ulcer formation (OR 8.97, 95% CI 2.10–38.36).ConclusionsWomen with IDD have increased odds having urinary and decubitus ulcer complications following hysterectomy, compared to women without IDD. These results inform surgical decision-making and anticipatory guidance for these women and their caregivers.  相似文献
