ObjectiveTo investigate the clinical application value of ultrasonic cardiac output monitor(USCOM) in volume therapy of patients treated with hip replacement and its effect on early prognosis.

MethodsOne hundred and twenty-six volume therapy patients treated with hip replacement were randomly divided into the observation group(USCOM monitoring fluid replacement, 63 cases) and control group(routine fluid replacement, 63 cases).The general information, clinical indicators, arterial blood lactic acid levels at different time points and occurrence of postoperative complications between two groups were compared.

ResultsThe differences of the baseline data of age, sex, body mass index, operation time, anesthesia time, ASA grade and complications between two groups were not statistically significant(P>0.05).The intraoperative bleeding volume, urine volume, total crystalloid volume, total transfusion volume and total hospitalization time in observation group were obviously lower than those in control group, and the colloid liquid volume in observation group was obviously higher than that in control group(P < 0.01).The differences of the vasoactive drugs usage between two groups was not statistically significant(P>0.05).The arterial blood lactate level in observation group was obviously lower than that in control group at T₁(P < 0.01), and the differences of the arterial blood lactate levels at other time-points between two groups were not statistically significant(P>0.05).The incidence rates of nausea, vomiting and nemia of postoperative complications in observation group were obviously lower than those in control group(P < 0.01).

ConclusionsThe clinical effects of USCOM in volume therapy of patients treated with hip replacement is significant, which can reduce the occurrence of postoperative complications and improve the early prognosis of patients.
