摘　　要：目的分析气腹后不同时点心排血量(CO)下降的相关因素。方法拟在腹腔镜下胆囊切除术患者60例,经食管超声心动图(TEE)实时监测患者气腹前后CO的变化。采用单因素Lo-gisitic回归法分析气腹后不同时点CO下降的因素。结果气腹后30min,与患者CO下降有统计学意义的因素是老年(χ2=12.22,P=0.001)、高血压(χ2=6.17,P=0.013)、高气腹压力(χ2=4.59,P=0.03)和超重(χ2=7.54,P=0.006);待放气后则仅有老年与CO下降相关,然而在气腹后即刻和头高位时,考察的因素与患者CO下降无关。结论在气腹后不同时间点,引起患者CO下降的相关因素是可变的。Objective To analyze the correlation factors of decreased cardiac output at different time after pneumoperitoneum. Methods Sixty patients undergoing laparoscopic cholecystectomy were enrolled, and the cardiac output was measured by transesophageal echocardiography. The relationship between correlation factors and decreased CO were analyzed through one way logistic regression and binary logistic. Results At 30 rain after CO decreased, and patients were statistically significant factor is the elderly, hypertension, high pressure pneumoperitoneum and overweight （in the following order： Z2 12.22, P=0.001; X2=6.17, P 0.013; Z2：4.59, P：0.03; Z2：7.54, P：0.006）; to be deflated only aged patients with CO associated with decreased, but the pneumoperitoneum after immediate and head high investigation of factors associated with patients, independent of CO decline. Conclusion In the different periods of pneumoperitoneum, the correlative factors of decreased CO is changeable.
