Detection of intraperitoneal free air is important for the diagnosing of life-threatening conditions in patients with acute abdominal pain. Point-of-care ultrasound is an extension of the clinical examination in patients presenting with acute abdomen. Failure of sonographers to detect intraperitoneal free air was clinically considered as a limitation of abdominal ultrasound. It is now increasingly appreciated that ultrasound may detect intraperitoneal free air. Emergency physicians should be familiar with the sonographic features of intraperitoneal free air which may be essential to recognize bowel perforation. Herein we review the literature on the sonographic findings of intraperitoneal free air and the technical manoeuvres that can improve clinicians' detection of intraperitoneal free air using point-of-care ultrasound.
检测腹腔内游离气体对于诊断急性腹痛患者的危及生命状况很重要。床旁超声是对急性腹痛患者进行临床检查的一种扩展。超声检查人员未能检测到腹腔内游离气体在临床上被视为腹部超声的一个局限性。现在人们越来越认识到超声可能检测到腹腔内游离气体。急诊医生应熟悉腹腔内游离气体的超声特征，这对于识别肠穿孔可能至关重要。在此，我们回顾了关于腹腔内游离气体超声表现的文献以及可改善临床医生使用床旁超声检测腹腔内游离气体的技术操作。
