目标
评估使用商业电话网络传输产科超声图的实时远程医疗链路的可靠性。
材料和方法
我们建立了综合服务数字网络 (ISDN)，由三个专用电话线组成，从三个卫星办公室连接到我们的中央产前诊断中心。所有患者均由经过培训的超声检查师将超声检查评估记录在录像带上。随后建立了实时交互式视频远程医疗链接，围产期专家指导超声检查师进行扫描。根据远程医疗检查结果出具了一份报告。记录获得满意的实时图像所需的呼叫次数以及传输不理想的原因。前 150 次传输被排除在本研究之外。对随后同意参与的 100 名患者的结果进行了分析。
结果
我们能够为所有 100 名计划使用远程医疗链接进行检查的患者提供产科解释。 85 例需要单次连接，5 例需要两次呼叫，8 例需要三次呼叫，1 例需要四次呼叫，另一例需要五次呼叫。因图像传输不良需重拨20起；其他重复通话原因为无法接通（5例）、通话断线（2例）、无图传（2例）。
结论
在社区提供产科超声检查远程医疗服务是可行的，但由于技术故障而需要重复连接，需要纳入成本和时间分析，以便提供系统效率的衡量标准。
OBJECTIVE
To evaluate the dependability of a live telemedicine link for the transmission of obstetric ultrasonograms using a commercial telephone network.
MATERIALS AND METHODS
We established an integrated services digital network (ISDN), consisting of three dedicated telephone lines from three satellite offices, to our central prenatal diagnostic center. All patients had a sonographic evaluation recorded on videotape by a trained sonographer. A live interactive video telemedicine link was then established, and a perinatologist directed the sonographer through the scan. A report was issued on the basis of the telemedicine examination. The number of calls required to obtain satisfactory real-time images was recorded, as were the reasons for suboptimal transmissions. The first 150 transmissions were excluded from this study. The results in the subsequent 100 patients who agreed to participate were analyzed.
RESULTS
We were able to provide obstetric interpretations in all 100 patients scheduled to be examined using the telemedicine link. A single connection was required in 85 cases, two calls in 5 cases, three calls in 8 cases, four calls in 1 case, and five calls in another case. A repeat call was required in 20 cases because of poor image transmission; other repeat calls were caused by failure to connect (5 cases), calls disconnected (2 cases), and no image transmission (2 cases).
CONCLUSIONS
The provision of telemedicine services for obstetric ultrasonography in the community is feasible, but the need for repeat connections because of technical failures needs to be incorporated into cost and time analyses in order to provide a measure of the system's efficiency.
