Popis: Evaluation of efficiency of technology in operation room was done almost subjectively in past. This does not fulfil the requirement of a reliable data pool. The goals of this study are a prototypic ontology for surgical procedures, a practicable form of workflow collection and the exemplary evaluation of surgical workflows by example of endonasal videoendoscopic sinus surgery (FESS). The study included altogether 38 FESS-procedures (20 patients). Surgical procedures were accomplished by 7 different surgeons with different degrees of training. For description of surgical procedures and resources, we used the standard EN1828/2001. For workflow modelling, we used the Workflow Reference Models (Workflow Management Coalition, WfMC) as a reference. 1029 different positions of the endoscope, summarized to 5 major-positions were documented. The average time in holding one endoscope position was 1.31 min. 27.1 changes of endoscope position were recorded at each side. 32% were caused by cleaning. 29 changes of surgical instruments were found. 48.3% are justified in the single-hand conception FESS. This study offers a discussion basis for development of ontology, recording and analysis of surgical workflows and their practical application. Our analysis proves the need for assistance by guiding the endoscope apart from surgeon's hand. Pre-conception details of a mechatronic system to solve the clinical requirements are based on workflow analysis. Analysis of complex surgical procedures and their modification will be a basis of future conceptions of technology in OR.
