Comparison between High- and Low-Cost Transmission of Tele-Anesthesia in Japan.

摘要: Background. We previously reported a tele-anesthesia system that connected Sado General Hospital (SGH) to Yokohama City University (YCUH) using dedicated virtual private network (VPN) guaranteed the quality of service. The study indicated certain unresolved problems, such as high cost constantly VPN for tele-anesthesia. In this study, we assessed whether use best-effort affects safety and in clinical setting. Methods. One hundred patients were enrolled study. provided 65 transmission (20 Mbit/s; guaranteed, 372,000 JPY per month: 1 JPY = US$0.01) 35 (100 Mbit/s; not 25,000 month). measured speed number commands completed from YCUH SGH during with both systems. Results. system, anesthesia duration was 5780 min (88.9 min/case) surgical 3513 min (54.0 min/case). 3725 min (106.4 min/case) 2105 min (60.1 min/case). average 17.3 ± 3.8 Mbit/s. an acceptable delay time frame rate use. All completed, no adverse events occurred Discussion. field tele-anesthesia, internet equivalent efficacy at better price compared system.
