RESUMO
Objective To observe value of high frequency ultrasound for inspection of T7-8 paravertebral space and adjacent structures.Methods Color Doppler ultrasonic diagnostic apparatus with linear array transducer (frequency 3-12 MHz) were used.Taking shoulder blade,ribs,thoracic spine and transverse process as anatomical marks,T7-8 paravertebral spaces of 30 normal adult (a total of 60 side) were examined.Ultrasonographic features of T7-8 paravertebral space and the adjacent structures were observed.Results T7-8 thoracic paravertebral showed as similar triangular shape with ultrasonography,interior solid homogeneously hypoechoic was noticed.Adjacent muscles of T7-8 paravertebral space included the trapezius,latissimus dorsi,spinalis,semispinalis,multifidus,rotatores and intercostal muscles.Color Doppler or power Doppler flow imaging could demonstrate posterior intercostal artery in the paravertebral space.Conclusion High frequency ultrasound can clearly show T7-8 paravertebral space and adjacent structures,thus providing ultrasonic references for clinical diagnosis and treatment of lesions of thoracic space and adjacent structures.
RESUMO
Acute laryngeal obstruction is one of the most common diseases in Department of ENT, and it can cause suffocation without prompt treatment. Methods by using Nasopharyngofiberoscope guided tracheal intubation treatment of a case of acute laryngeal obstruction patients in a timely manner. This method is well tolerated, less trauma, high success rate, in the shortest time to improve the patient's ventilation, for the next step of the treatment to win the time.
