摘　　要：目的评价床旁超声确定胃窦横截面积(CSA)判断慢性乙肝患者空腹的价值。方法择期行胃镜检查术的慢性乙肝患者159例,年龄18~64岁,身高>150 cm,体重45~110 kg。患者取仰卧位,利用床旁超声设备测量胃窦的头尾径和前后径,计算CSA。患者行胃镜检查结束时,利用胃镜负压吸引胃内液体并进行测量,以胃液量≤0.8 ml/kg作为空腹的标准。结果床旁超声确定CSA判断慢性乙肝患者空腹的临界值为440 mm^2,灵敏度为85.07%,特异度为80.95%,阳性预测值为96.61%,阴性预测值为45.95%,符合率为84.52%。结论对于慢性乙肝患者,床旁超声确定CSA预测空腹的临界值为440 mm^2。Objective To evaluate the value of bedside ultrasound-measured antral cross-sectional area(CSA)in diagnosing an empty stomach in patients with chronic hepatitis B.Methods One hundred and fifty-nine patients with chronic hepatitis B,aged 18-64 yr,with body height>150 cm,weighing 45-110 kg,were enrolled in this study.The antero-posterior diameter and craniocaudal diameter of the gastric antrum were measured by bedside ultrasound when patients were in the supine position,and CSA was calculated.Gastroscope negative pressure was used to suction fluid from stomach at the end of gastroscopy,and the fluid volume was recorded,and gastric fluid volume≤0.8 ml/kg was defined as the standard for empty stomach.Results The cut-off value of CSA measured by bedside ultrasound in diagnosing an empty stomach was 440 mm^2,with sensitivity 85.07%,specificity 80.95%,positive predictive value 96.61%,negative predictive value 45.95%,coincidence rate 84.52%.Conclusion The cut-off value of bedside ultrasound-measured CSA in diagnosing an empty stomach is 440 mm^2 for the patients with chronic hepatitis B.
