Commonly used preoperative diagnostic procedures were analyzed for their ability to predict the presence of early ectopic pregnancy. Patients presenting to the emergency room with acute onset of pelvic pain were evaluated with culdocentesis, pelvic ultrasonography, and qualitative serum and urine pregnancy testing. Clinical examination and urine pregnancy testing were found to be poor predictors of either the presence or absence of an early ectopic pregnancy. The combination of a sensitive serum human chorionic gonadotropin (hCG) determination and pelvic ultrasonography accurately predicted ectopic pregnancy in 93% of proved cases. This predicted accuracy was superior to that of culdocentesis alone or in combinations of culdocentesis and ultrasound or qualitative serum pregnancy testing.
分析了常用的术前诊断程序预测早期异位妊娠存在的能力。对因急性盆腔疼痛到急诊室就诊的患者进行了后穹窿穿刺、盆腔超声检查以及血清和尿液定性妊娠试验。发现临床检查和尿液妊娠试验对早期异位妊娠的存在与否预测能力较差。敏感的血清人绒毛膜促性腺激素（hCG）测定与盆腔超声检查相结合，在93%的确诊病例中准确预测了异位妊娠。这种预测准确性优于单独的后穹窿穿刺，或后穹窿穿刺与超声检查或血清定性妊娠试验联合使用的情况。
