Abstract: OBJECTIVE To understand the current status of physical insulation during perioperative periods in secondary and tertiary medical institutions in Guizhou Province. METHODSBased on the "Guizhou Province 'Perioperative Inspection' Action Implementation Plan", a "Perioperative Insulation Measure Survey Form" was developed, and a survey was conducted among 158 medical institutions (104 at the secondary level and 54 at the tertiary level). The survey content included basic information about medical institutions (hospital level, hospital type, surgical operating rooms, etc.), perioperative insulation management mechanisms (organizational construction, personnel training, quality control assessment and information management) and the current status of perioperative insulation measures (passive and active environmental insulation before, during and after surgery). RESULTSIn terms of management, 63.29% of medical institutions across the province incorporated perioperative insulation into their surgical safety improvement plans (90.91% in Qianxinan Prefecture vs. 25.00% in Anshun City), 46.84% conducted preoperative hypothermia risk assessments (73.33% in Liupanshui City vs. 23.81% in Qiandongnan Prefecture), 36.08% established intraoperative special inspections, with a perioperative insulation training implementation rate of 62.66% (anesthesiologist participation rate of 60.13% and circulating nurse participation rate of 65.82%), and only 5.06% of institutions achieved quarterly standardized training. In terms of temperature monitoring, 63.50% conducted core temperature monitoring, only 39.24% achieved continuous monitoring (47.83% in Guiyang City vs. 16.67% in Qiannan Prefecture), and only 17.72% achieved fully information-based precision monitoring. In terms of equipment configuration, the highest rates of active heating equipment deployment were for intravenous fluid heating (22.18%), heaters (16.77%) and inflatable heating (9.44%), with regional differences. CONCLUSIONA preliminary management framework for perioperative insulation management has been established in Guizhou Province, but issues such as imperfect institutional construction, inadequate temperature monitoring capabilities and low deployment rates of active insulation equipment remain prevalent, with significant regional differences. It is recommended to optimize training programs through regional collaboration mechanisms, strengthen the construction of a continuous and precise intraoperative temperature monitoring system, and improve the deployment rate of insulation equipment.
