CLOSED CIRCUIT ANAESTHESIA

'Closed circuit' anaesthesia.

Aa inhalation anaesthetic is like a concerto-conducted in three movements, if one ignores the surgical cadenzas. The three movements of the well-conducted anaesthetic are: The induction, during which the patient is introduced to and thereafter loaded with an anaesthetic drug to produce a general tissue concentration sufficient for anaesthesia. The brain, with its rich blood supply, leads the ti...

A versatile closed circuit.

A versatile closed circuit with new features is described. It may be used in a totally closed manner, without continuous gas inflow. As gas is absorbed from the circuit, it is replaced through a demand valve. Facilities for continuous gas input and use of a ventilator are included, and one control converts it to a non-rebreathing circuit. The circuit has excellent mechanical characteristics in ...

Closed Loop Anaesthesia Delivery System (CLADS) - Anaesthesia Robot

With the advancement in microprocessor technology and development of objective anaesthesiadepth indicators, the use of automated anaesthesia deliver system using feedback from differentEEG derived parameters has become a reality. The anaesthetic drugs can be delivered based onpatients’ individual requirement using computer controlled syringe infusion pumps. CLADS is anindige...

Closed-loop Controlled Total Intra Venous Anaesthesia

Time course of inhaled anaesthetic drug delivery using a new multifunctional closed-circuit anaesthesia ventilator. In vitro comparison with a classical anaesthesia machine.

BACKGROUND The aim of this study was to detail the time-course, defined as the changes in end-tidal drug concentration with time, and consumption of inhaled anaesthetics when using a multifunctional closed-circuit anaesthesia machine in various drug delivery modes, and to compare it with a classical anaesthesia machine using an out-of-circle vaporizer under high and low fresh gas flow condition...
