Clinical application of Univent課件

1、四川大學(xué)華西醫(yī)院麻醉科梁 鵬Clinical application of UniventUnivent introductionThe Univent is a single-lumen silicone tube with a small separate lumen along the anterior concave wall which contains a small hollow nonlatex bronchial blocker that can extend about 8-10 cm beyond the tip. The Univent can block either

2、 the left or right bronchus when inserted through the specially designed endotracheal tube.Univent introductionThe device incorporates a flexible, high torque control blocker with a soft, open lumen tip improving the ability to manipulate and direct the blocker during a procedure.Smooth Intubation T

Endotracheal intubation can be performed in the conventional manner, just like a single lume

5、n endotracheal tube.2. One-lung ventilation can be achieved by placement of the blocker to either the left or right lung, or to lung segments in either lung.3. Insufflation and CPAP can be achieved through the lumen of the blocker shaft.4. Blocked lung can be collapsed by aspirating air through the

6、blocker lumen.5. The blocker can be retracted into its pocket to facilitate post operative ventilation.Endotracheal tube with an easy-to-direct torque control blockerThe Univent allows collapsing of one lung for thoracoscopic procedures.Endotracheal intubation can be performed in the conventional ma

7、nner, just like asingle lumen endotracheal tube. One-lung ventilation can be achieved by placement of the blocker in either the left or right lung, or lung segments. The blocked lung can be collapsed by aspirating air through the lumen of the blocker shaft.Insufflation and PEEP can also be achieved

8、through the lumen of the blocker shaft.Warnings and PrecautionsAbout Stylets and Aeration Capa) The stylets on both ends of the blocker should be removed and discarded prior to use, as they are placed to maintain the curved shape of the blocker.b) The aeration cap (blue color) attached at the blocke

9、r valve should also be removed and discarded prior to use, as it is attached for ventilation during EOG sterilization process.Warnings and PrecautionsAbout Retraction of Blocker Cuffa) Before retracting the blocker cuff, be sure to evacuate air completely from the cuff (until the pilot balloon is al

10、so collapsed) for smooth retraction.b) Lubricant (such as Lidocaine jelly) should be applied on the whole surface of the blocker cuff.c) Pull the blocker carefully until the setting end mark (double-end mark) appears at the proximal end of the blocker mantle tube and retract the blocker cuff into th

11、e pocket of the endotracheal tube.d) Do not apply lubricant on the tip end of the blocker shaft as the lubricant may obstruct the blocker shaft lumen.Warnings and Precautionse) Do not pull the blocker shaft with excessive force when the setting end mark appears. It may damage the blocker cuff.f) In

12、case the tip end of the blocker shaft cant be retracted into the pocket of the endotracheal tube, the tube should not be used.Warnings and PrecautionsAbout CuffsConduct inflation test for tracheal cuff and blocker cuff prior to use. In case any malfunction such as air leakage or balloon herniation h

13、as occurred, the tube should not be used.Maximum injection air volume (for inflation test) for tracheal cuff per size:For I.D. 6.0, 6.5, and 7.0mm max. 40mLFor I.D. 7.5, 8.0, 8.5, 9.0, 9.5and 10.0mm max. 50mLMaximum injection air volume (for inflation test) for blocker cuff per size: All sizes max.

14、6mL* Do not over inflate as above specified for inflation test.Intubation MethodsA. Tube Rotation MethodInsert the tube orotracheally just like a conventional endotracheal tube and rotate the tube 90 degrees towards the operative side, so that the blocker lumen is on the thoracotomy side(Fig.1)Intubation MethodsB. Blocker Rotation MethodInsert the tube orotracheally, inflate the tracheal tube cuff and fix the tube firmly at the patients mouth with cloth tape.Insert FOB into the endotracheal tube lumen and pu
