About

With the development of society, the number of emergency critical operations is increasing year by year. Traditionally, the patient's systemic and circulatory status is indirectly assessed by testing and blood pressure heart rate. There are cases where the diagnosis is imperfect and the results are unreliable. Preoperative POU rapid ultrasound is a preoperative bedside ultrasound evaluation method first proposed by the Anesthesiology Department of Huaxi Hospital (three engineering units). This project will cooperate with Huaxi Hospital to explore whether the effect of intraoperative anesthesia management under POU guidance is better than traditional anesthesia management. This study will provide a new preoperative evaluation anesthesia management program for emergency critically ill patients with important clinical and social significance.

Full description

According to the inclusion and exclusion criteria, the patients will be randomly divided into two groups：In the control group, the anesthesiologist performed according to the existing preoperative evaluation program and existing experience, and guided the anesthesia management with the evaluation results.The experimental group used POU protocol ultrasound to perform a heart scan and a standard scan, a large vascular scan under the xiphoid, a body cavity scan, a standard section, and a lung scan in 10 minutes. Comprehensive preoperative circulation and assessment of systemic conditions, and guided intraoperative anesthesia management with assessment results.
