Closed system anaesthesia

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 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...

Closed-loop Controlled Total Intra Venous Anaesthesia

Quantitative study of Lowe's square-root-of-time method of closed-system anaesthesia.

Intermittent injection of liquid anaesthetic into a closed breathing system is particularly suitable in countries with limited resources. A method of calculating appropriate times and magnitudes of the injected doses was described by Lowe but the method has never been assessed rigorously. Such an assessment was the purpose of this study. The technique was used in a double-blind, randomized comp...

Anaesthesia for closed embolisation of cerebral arteriovenous malformations.

Cerebral arteriovenous malformation embolisation is a therapeutic, neuroradiological procedure involving injection of bucrylate glue into the nidus of the AV malformation to obliterate the abnormal vascular network. These procedures may involve significant risks, are often long and thereby necessitate the need for some form of sedation and for adequate monitoring of the cerebral, cardiovascular...
