The practical application of foetal blood sampling in the routine management of patients in labour has been reviewed in a six-month survey, during which time 1,668 patients were delivered at Queen Charlotte's Hospital.Foetal acidaemia (pH 7.25 or less) occurred in 45 of the 295 patients who showed clinical signs of foetal distress. Foetal tachycardia was the presenting sign in 33 of these 45 patients, underlining the importance of this physical sign. Foetal acidaemia in association with clinical foetal distress occurred twice as often in patients who had complications of pregnancy and who were therefore regarded as obstetrically "at risk" as it did in patients who were obstetrically "normal" No cases of acidaemia were detected in any of the foetal blood samples performed routinely on "at-risk" patients in the absence of clinical foetal distress.
在一项为期六个月的调查中，对胎儿采血在分娩期患者常规管理中的实际应用进行了评估。在此期间，有1668名患者在夏洛特女王医院分娩。在295名出现胎儿窘迫临床体征的患者中，有45名出现胎儿酸血症（pH值7.25或更低）。这45名患者中有33名以胎儿心动过速为首发体征，凸显了这一体征的重要性。与临床胎儿窘迫相关的胎儿酸血症在患有妊娠并发症、因而被视为产科“高危”的患者中出现的频率是产科“正常”患者的两倍。在没有临床胎儿窘迫的情况下，对“高危”患者进行的常规胎儿血样检测中未发现任何酸血症病例。
