TY - T1的体内超声评估呼吸功能腹部肌肉的正常受试者JF -欧洲呼吸杂志》乔和J SP - 2861 LP - 2867欧元六世- 10 - 12盟Misuri G盟——Colagrande年代盟——Gorini M AU - Iandelli,我非盟——曼奇尼,米非盟- Duranti R盟——Scano最近，超声被提出用于评估人类在收缩过程中膈肌的厚度和运动的变化。关于超声评估人类腹肌的数据是稀缺的。因此，我们研究了在正常受试者呼吸动作中使用该技术腹肌厚度的变化和相关的力学效应。我们使用7.5 MHz b型超声换能器评估了6名正常男性(年龄26-36岁)腹肌层的厚度。采用功能性剩余容量(FRC)、残余容积(RV)、总肺活量(TLC)、胃压力(Pg)、口压(Pg)、腹外斜肌(EO)、腹内斜肌(IO)、腹横肌(TA)、腹直肌(RA)进行肌厚度测定。在进行性(PEEs)和最大呼气力(MEEs)对关闭的气道，以及在同侧(HTR)和对侧(CTR)躯干旋转期间。腹肌厚度具有可重复性(变异系数和双向方差分析)。与FRC相比，在RV和MEEs期间，IO、TA和RA的厚度显著增加，而EO保持不变;TLC时，IO和TA的厚度明显减小。 During PEEs, a significant relationship between increase in Pg and TA thickness was observed in all subjects, the thickness of the other abdominal muscles being inconsistently related to Pg. Finally, a significant increase in the thickness of IO and EO was found during HTR and CTR, respectively. We conclude that during maximal expiratory manoeuvres, transversus abdominis, internal oblique and rectus abdominis thickened similarly. Transversus abdominis seems to be the major contributor in generating abdominal expiratory pressure during progressive expiratory efforts. External oblique seems to be preferentially involved during trunk rotation. These results suggest the possible value of studying the abdominal muscles by ultrasonography in various respiratory disorders. ER -
