Background and objective: Patients who received anesthesia service required anesthesia equipments aims to monitor and care during anesthetic. At department of anesthesiology, faculty of medicine, Khon Kaen university, we have 1,020 anesthesia equipments for 20 operating rooms and 2 post anesthetic care units. Although, we checked them daily, losing equipment always happen. So, losing prevention is very importance. This study aims to develop the anesthetic equipment losing prevention guideline by brainstorming technique and study the losing incidence after guideline launched.

Method: This study was descriptive study. We studied between 1 January 2009 - 31 December 2011 at department of anesthesiology. Brainstorming group was included personnel in department (nurse anesthetists, nurse anesthetist students, residents) and others unit (operating nurse, critical care nurse, laundry personnel) aimed to search problem, find prevention technique, and develop the guideline. Then we introduced the guideline to all personnel and have campaign for prevention. We also recorded incidence of anesthetic loss.

Results: One hundred and thirty seven personnel were included into study. After guideline launched, losing incidence in year 2010, 20111 were lesser than in year 2009. In year 2009, 18 pieces were loss (cost 40,000 baht). In year 2010, 16 pieces were loss (12 % reduction) and cost was 7,063 baht (82.3 % reduction). In year 2011, 7 pieces were loss (62 % reduction) and cost was 4,500 baht (88.8 % reduction).

Conclusion: Guideline for prevention of anesthetic equipment loss. That developed by brain storming technique including campaign for prevention can reduce losing incidence and reduce the cost for replacement.
