Two operating rooms were newly constructed to facilitate the increasing need of surgical services in our university hospital. After a half year of use, the oxygen delivery was suddenly blocked in one of them. Fortunately, the serious incident did not occur because an anesthesiologist identified the blockage of oxygen flow when he checked the anesthesia machine prior to the patient arriving in the operating room. Upon investigation we found the structural defects in ceiling column of that operating room. The pipe containing nitrous oxide and its structural support touched the valve of oxygen supply. It appears that the valve was gradually turned off by this contact while the ceiling column was moved up and down. Once this structural defect had been repaired, there was no longer any incident of the accidental blockage of oxygen to the operating room.
新建了两间手术室，以满足我校医院日益增长的手术服务需求。使用半年后，其中一间手术室的氧气输送突然受阻。幸运的是，由于一名麻醉师在患者进入手术室前检查麻醉机时发现了氧气流通受阻，严重事故并未发生。经调查，我们发现该手术室天花板立柱存在结构缺陷。装有一氧化二氮的管道及其结构支撑物碰到了氧气供应阀。当天花板立柱上下移动时，阀门似乎因这种接触而逐渐关闭。一旦修复了这一结构缺陷，手术室氧气意外受阻的情况就再也没有发生过。
