Triage and Evaluation of Blast-Injured Patients in Wenling Liquefied Petroleum Gas Tanker Explosion.

This article focuses on the mass casualty emergency response and injury characteristics following a liquefied petroleum gas (LPG) tanker explosion in Wenling, Zhejiang Province, China, on June 13, 2020. The study analyzed medical records of 176 inpatients with blast injuries treated at eight hospitals, categorizing injuries by the new injury severity score (NISS) and detailing the distribution of primary, secondary, tertiary, and quaternary blast injuries, with burns and inhalation injuries prevalent among severely affected patients. The emergency response involved rapid triage and transport to multiple hospitals based on injury severity, with severe cases transferred to specialized tertiary centers, including the Second Affiliated Hospital of Zhejiang University School of Medicine. The findings highlight the importance of coordinated local and regional medical resources, accurate triage, and multidisciplinary care in managing large-scale LPG explosion casualties and provide insights to improve preparedness for future mass-casualty incidents.
