To compare the accuracy of transperineal (TP) ultrasound with transabdominal (TA) approach in the sonographic assessment of fetal occiput position during the second stage of labour.
A series of low-risk women at term attending the labour ward of three university hospitals were prospectively recruited for the purpose of this study. During the second stage of labor patients were evaluated first by TP and than by TA ultrasound to determine the fetal position. The occiput position was labelled as DOA (direct occiput anterior), ROA (right occiput anterior), LOA (left occiput anterior), DOP (direct occiput posterior), ROP (right occiput posterior), LOP (left occiput posterior), ROT (right occuput transverse) and LOT (left occiput transverse). The agreement between the two techniques was assessed.
Overall 80 patients were recruited in the study group. Ultrasound examination was performed at 21(± 8) minutes from the beginning of the active pushing. The ultrasound findings of the fetal occiput position were recorded. In all cases TA ultrasound confirmed the fetal occiput position as determined at TP approach except in one case of ROA that had been recorded as ROT using TP ultrasound.
Ultrasound TP examination is accurate in the diagnosis of fetal occiput position during the second stage of labor.
比较经会阴（TP）超声与经腹（TA）超声在产程第二阶段对胎儿枕骨位置进行超声评估时的准确性。
前瞻性招募了一系列在三家大学医院产科病房就诊的足月低风险孕妇参与本研究。在产程第二阶段，先通过TP超声对患者进行评估，然后再通过TA超声确定胎儿位置。枕骨位置标记为枕前位（DOA）、右枕前位（ROA）、左枕前位（LOA）、枕后位（DOP）、右枕后位（ROP）、左枕后位（LOP）、右枕横位（ROT）和左枕横位（LOT）。评估了两种技术之间的一致性。
研究组共招募了80例患者。在开始用力21（±8）分钟时进行了超声检查。记录了胎儿枕骨位置的超声检查结果。在所有病例中，TA超声均证实了TP超声所确定的胎儿枕骨位置，但有一例ROA在TP超声检查中被记录为ROT。
超声TP检查在产程第二阶段诊断胎儿枕骨位置方面是准确的。
