[Characteristics of the confined space accident and its medical rescue strategy].

Abstract

Objective: To investigate the characteristics of the confined space accident and its medical rescue strategy.

Methods: Thirty-six patients with emergency rescue in the five confined space accident during June 2009 to July 2012 were retrospectively analyzed.

Results: Twenty-nine people were caught in four confined space accidents caused by building collapse and 7 people were caught in one confined space accident caused by a tower of babel blast furnace damage which caused severe gas and hydrogen sulfide poisoning. For the 36 wounded, the shortest rescue time was 1.5 hours and the longest was 10.5 hours. Fourteen people were killed (mortality rate 38.89%). Characteristics of the confined space accident: the wounded activity environment was very harsh, the wounded were restricted particularly, the wounded injuries were diverse, the psychological depression was very common. The confined space environment and the complexity of wounded disease determined its medical rescue specificity and were very different from the usual trauma emergency.

Conclusions: Confined space accident caused very painful casualties. The key reason is that the relevant personnel failed to clearly recognize the potential risks in the confined space or nearby, making the confined space into another "quiet killer". This problem needs to be paid highly attention.
