Objectives:
The rapid ultrasound in shock examination (RUSH process) is an assessment of patient's heart function, volume status, and vasculature, which can help anesthesiologist understand the patient's physical condition. In this study, the RUSH process was applied to elderly emergency surgery patients to evaluate whether it is beneficial to maintain the patient's vital signs stable during the operation.
Methods:
In this randomized controlled clinical study one hundred elderly patients who needed general anesthesia and emergency surgery from January 2021 to July 2021 were randomly divided into RUSH group (Group-A, n=52) and control group (Group-B, n=48). The main result include the area under the intraoperative blood pressure curve (AUC), liquid input, urine output, lactic acid levels, number of vasoactive drugs used.
Results:
There were no significant differences in patients' basic information, preoperative blood pressure, intraoperative blood loss, intraoperative fluid input, intraoperative blood transfusion, and urine output. Intraoperative systolic blood pressure less than 90mmHg AUC of Group-A is less than Group-B(P<0.05), diastolic blood pressure less than 60mmHg AUC of Group-A is less than Group-B(P<0.05). After the operation, the blood gas analysis lactic acid level in Group-A was lower than that in Group-B(P<0.05). Group-A used more vasoactive drugs than Group-B(P<0.05).
Conclusion:
The bedside ultrasound RUSH process is of great significance for anesthesiologist to understand the preoperative physical condition of elderly emergency surgery patients, and is beneficial to maintain the stability of intraoperative vital signs.
