Routine measurement of abdominal girth after suspected trauma is still recommended as a predictor of intraperitoneal bleeding but there is little evidence to support its accuracy. Girth measurements were taken on 12 recumbent adult patients by independent observers and repeated after infusion of 550 ml aliquots of dialysate to a maximum of 2000 ml. Girth increase per 500 ml infusion varied from -0.46 cm to 2.1 cm (mean 0.84 +/- 0.65 SD) giving a range in excess of 2.5 cm. In some cases the girth decreased after a further 500 ml infusion. A change in patient position altered the girth at a constant volume by 1.32 cm (+/- 0.75 SD). Observer error was low at 0.33 cm (+/- 0.35 SD). These results preclude girth as a reliable clinical indicator of intraperitoneal haemorrhage.
对于疑似创伤患者，仍建议常规测量腹围以预测腹腔内出血，但几乎没有证据支持其准确性。由独立观察者对12名仰卧成年患者进行腹围测量，并在每次输注550毫升透析液直至最大量2000毫升后重复测量。每输注500毫升腹围增加量从-0.46厘米至2.1厘米不等（平均0.84±0.65标准差），范围超过2.5厘米。在某些情况下，再输注500毫升后腹围减小。患者体位改变会使相同容量下的腹围改变1.32厘米（±0.75标准差）。观察者误差较低，为0.33厘米（±0.35标准差）。这些结果表明腹围不能作为腹腔内出血可靠的临床指标。
