Peripheral regional nerve blockade (nerve block) is used in anesthesia to administer anesthesia to certain regions of the body. During nerve block the anesthetic is injected directly into or around the area surrounding the nerve. One of the most critical components of ultrasound-guided nerve blocks is the detection of the nerve within the ultrasound image.(More)
Closed-loop systems for propofol have been demonstrated to be safe and reliable for general anesthesia. However, no study has been conducted using a closed-loop system specifically designed for sedation in patients under spinal anesthesia. We developed an automatic anesthesia sedation system that allows for closed-loop delivery of propofol for sedation(More)
BACKGROUND We have developed an automatic anaesthesia system for closed-loop administration of anaesthesia drugs. The control variables used were bispectral index (BIS) and Analgoscore for hypnosis and antinociception, respectively. METHODS One hundred and eighty-six patients were randomly enrolled in two groups. Propofol, remifentanil, and rocuronium(More)
Editor’s key points † Automatic feedback control depends on having a reliable, measurable control variable. † An automatic system for closed-loop administration of i.v. anaesthesia drugs was compared with manual control. † Bispectral index and a compound analgesia score were used as the target controls. † Time within excellent (≤10%) and good (11–20%) range(More)
Editor’s key points † A novel robot assistance nerve block system has been recently developed and tested in patients. † This study investigated the role of this system in training in ultrasound-guided nerve blocks. † The robot system reduced inter-subject variability, with faster learning of needle placement than manual techniques. † This new approach to(More)
Our goal in this study was to develop a robotic intubation system and to conduct a feasibility pilot study on the use of a robotic intubation system for endotracheal intubations. The Kepler Intubation System was developed, consisting of a remote control center (joystick and intubation cockpit) linked to a standard videolaryngoscope via a robotic arm. Ninety(More)
Nerve blocks are common procedures used to remove sensation from a specific region of the body via injection of local anesthetic. Ultrasound-guided nerve blocks are common-place in anesthesia, but require specialized training and advanced bi-manual dexterity. This paper describes a system designed to robotically assist in ultrasoundguided nerve blocks.(More)
BACKGROUND Intubation is one of the most important anaesthetic skills. We developed a robotic intubation system (Kepler intubation system, KIS) for oral tracheal intubation. METHODS In this pilot study, 12 patients were enrolled after approval of the local Ethics board and written informed consent. The KIS consists of four main components: a ThrustMaster(More)
Anesthesia consists of three components: unconsciousness, analgesia and neuromuscular blockade (NMB). A specific drug is administered by the anesthesiologist to control these different components. In this paper we propose a new system for monitoring the neuromuscular blockade in anesthesized patients during surgery. Neuromuscular blockade drugs are used(More)
BACKGROUND Although telemedicine is one of the key initiatives of the World Health Organization, no study has explored the feasibility and efficacy of teleanaesthesia. This bi-centre pilot study investigates the feasibility of transcontinental anaesthesia. METHODS Twenty patients aged ≥ 18 yr undergoing elective thyroid surgery for ≥ 30 min were enrolled(More)
