目的探讨应用腹腔血人绒毛膜促性腺激素(HCG)定性检测诊断异位妊娠的临床效果。方法选择妇产科腹腔内出血急腹症患者56例,术前采用HCG检测试纸对患者腹腔血、静脉血、尿同时进行定性检测,结合术后临床诊断,观察3种检测方法诊断异位妊娠的特异度、灵敏度、阳性预测率、诊断正确率,评估与分析3种方法的临床效果。结果探查术后确诊异位妊娠46例。3种定性检测方法在特异度和灵敏度方面,腹腔血HCG定性检测优于静脉血HCG定性检测和尿HCG定性检测。腹腔血HCG定性检测的诊断正确率(97.83%)优于静脉血HCG定性检测正确率(81.30%),亦优于尿HCG定性检测(66.96%),差异有统计学意义(P<0.05)。结论腹腔血HCG定性检测可作为异位妊娠腹腔内出血治疗前或术前诊断首选化验诊断方法,具有简单快捷、费用低廉、诊断准确的优点。
Objective To investigate the clinical effect of qualitative detection of HCG in the diagnosis of ectopic pregnancy by intraperitoneal injection of human chorionic gonadotropin (HCG). Methods 56 patients with acute abdomen intraabdominal hemorrhage in obstetrics and gynecology were selected. HCG test strips were used before surgery to detect the blood, venous blood and urine in patients with abdominal ailments simultaneously. Combined with postoperative clinical diagnosis and observation, 3 kinds of detection methods were used to diagnose ectopic pregnancy Specificity, sensitivity, positive predictive rate, diagnostic accuracy, assessment and analysis of three kinds of clinical effects. Results 46 cases of postoperative ectopic pregnancy confirmed. Three kinds of qualitative detection methods in the specificity and sensitivity, qualitative detection of HCG in the peritoneal blood is better than qualitative detection of HCG in venous blood and urine HCG qualitative detection. The accuracy rate of qualitative detection of HCG in celiac blood (97.83%) was superior to that of qualitative detection of HCG in blood (81.30%) and qualitatively (68.96%) in HCG, the difference was statistically significant (P <0.05). Conclusion The qualitative detection of peritoneal blood HCG can be used as preoperative or preoperative diagnostic test for ectopic pregnancy intraperitoneal hemorrhage, which has the advantages of simple and quick, low cost and accurate diagnosis.
