Computer-assisted propofol administration.The use of propofol for sedation in endoscopy may allow for better quality of sedation, quicker recovery and facilitate greater throughput in endoscopy units. The cost-effectiveness and utility of propofol sedation for endoscopic procedures is contingent on the personnel and resources required to carry out the procedure. Computer-based platforms are based on the patients response to stimulation and physiologic parameters. They offer an appealing means of delivering safe and effective doses of propofol. One such means is the bispectral index where continuous EEG recordings are used to assess the degree of sedation. Another is the closed-loop target-controlled system where a set of physical parameters, such as muscle relaxation and auditory-evoked potential, determine a level of medication appropriate to achieve sedation. Patient-controlled platforms may also be used. These electronic adjuncts may help endoscopists who wish to adopt propofol sedation to change current practices with greater confidence.
