结论
在食管癌患者手术过程中使用BB和DLT均可完成有效的单肺通气,从而保
证手术的顺利进行,两种单肺通气方式各有其优缺点,使用BB行单肺通气对呼
吸力学和血气参数的影响较DLT小,具有很好的临床应用价值。

Theelllaihcnorbbronc ial
blockers(BB)and double—lumen
endotracheal tube
(DLT)in the
respiratory mechanics and blood gas in
one--lung ventilation in esophageal carcinoma patients
Obj ective
Among the thoracic surgeries,we usually implement one-lung ventilation by lung
isolation technology.In the lung of isolation technology,one of the two most popular
method is dual chamber intubation techniques,Another is single lumen endobronchial
intubation implementation obstruction technology.T.wo kinds of method may complete
one-lung ventilation.The present study was designed
to
seek the feasibility of bronchial
blocker for single lung ventilation and we will
contrast
the two ventilation ways of
advantages and diaadvantages in
a
single lung ventilation
as
well
as
to compare the
influence between the BB and DLT during
one-lung
ventilation in the respiratory
mechanics and blood gas in esophageal carcinoma patients.
Methods
The 40 esophageal
cancer
patients were divided into BB
group(20 cases)and
DLT
group(20 caLses)by
COINS method randomly.In BB group,BB Was intubated under
the guidance of
a
fiberoptic bronchoscope after intubation of single
lumen tube.While
in DLT group,DLT was intubated with
a
fiberoptic bronchoscopy
examining
the DLT
location.We would record the peek airway pressure(Paw)and the pulmonary
dynamic
compliance(Cdyn)of
the double lung ventilation
and
single
lung
ventilation,Blood
samples
were taken from radial artery after single lung ventilation 20 min for blood
analysis:partial

artery(Pa02),partial
