Controlled Clinical TrialEnd-tidal versus manually-controlled low-flow anaesthesia.
During low-flow manually-controlled anaesthesia (MCA) the anaesthetist needs constantly adjust end-tidal oxygen (EtO2) and anaesthetic concentrations (EtAA) to assure an adequate and safe anaesthesia. Recently introduced anaesthetic machines can automatically maintain those variables at target values, avoiding the burden on the anaesthetist. End-tidal-controlled anaesthesia (EtCA) and MCA provided by the same anaesthetic machine under the same fresh gas flow were compared. ⋯ In MCA patients the number of manual adjustments to stabilize EtAA and EtO2 were 137 and 107, respectively; no adjustment was required in EtCA. Low-flow anaesthesia delivered with an anaesthetic machine able to automatically control EtAA and EtO2 provided the same clinical stability and avoided the continuous manual adjustment of delivered sevoflurane and oxygen concentrations. Hence, the anaesthetist could dedicate more time to the patient and operating room activities.

FaceTime(®) for teaching ultrasound-guided anesthetic procedures in remote place.
In isolated area in Japan, only one anesthesiologist must often do new anesthetic techniques such as ultrasound-guided procedures without receiving any teaching. One solution to this problem may involve teleanesthesia, by which experienced anesthesiologists teach novices in remote places, by utilizing information communication technologies. FaceTime™ (Apple, USA), which provides 120p of the resolution and 30 frames per second (fps) is an application of free visual communications using iPod Touch™, iPhone™ or iPad™ (Apple, USA). ⋯ The delay time of iPhone5 was significantly longer than the others (iPod Touch; 0.14 ± 0.02 s, iPhone4; 0.13 ± 0.02 s, iPhone5; 0.19 ± 0.03 s), but clinically acceptable. The loss of the frames of iPhone5 (20; 1.1%) was significantly less than the others (iPhone4; 900, 50.0%, iPod Touch; 902, 50.1%). To teach anesthetic techniques in remote place by FaceTime, iPhone5 as the devise in isolate site was optimum compared with iPod Touch and iPhone4.
