- 2. STANDARD ENDOTRACHEAL TUBEDESIGN 1. Patient End 2. Curvature 3. Markings 4. Material 5. Size 6. Tube Cuff 7. Machine End
- 3. Material 1.Red Rubber/Natural Latex •Reusable • Rigid • Less traumatic • Opaque • Repated washing makes it soft & kinkable • Can be allergic 2. PVC • Inexpensive • Compatible with tissue • Disposable • Presterilised • Transparent • Rigid • Difficult to insert • Traumatic 3. Silicon Ruber • PVC+Silicon Oil • Less surface adhesion • Opaque • Inexpensive • Can be reused after autoclaving
- 4. SPECIAL TUBES 1. ColeType: Emergency Neonatal Resucitation : Narrow Patient end : Shoulder prevents broncheal intubation & provides air tight seal : Size is same as ID of patient end. : Can get blocked easily. : Resistance offered is more than normal ET tube of same size.
- 5. 2. Microcuff ETtube : cuffed tube for children : Short ultrathin cuff away from subglottic area :Can be inflated at very less pressure : No murphy's Eye : So cuff can be placed too distal : Reduced risk of pressure to Cricoid.
- 6. 3. RAE type: Ring Adain Elwin Tube : Oral/South Polar RAE : Nasal/North Polar RAE : Used to facilitate surgeries of Head & face. : South polar RAE has connector placed towrads chin giving better view during cleft palate surgeries. : North polar RAE is nasal so connector placed away from jaw giving better access to mandible. : Have disadvantage of not being able to pass suction catheter through it.
- 7. 4. Flexometalic tube: Head & Neck surgery with high movements : Reinforced with wire within the tube. : Flexible & Non kinking : More esily slipped over fibreoptic broncoscope : No nasal entubation possible : No Murphy's Eye : Expensive : Spontaneous extubation can happen : May obstruct the radiological view of Cx Spine
- 8. 6. Microlaryngeal Tube: Microlaryngeal surgeries & with narrow airway. : Available as 4,5 or 6 sized tube. : High volume low pressure cuff. : Can be inserted through LMA : Forcep is required during intubation.
- 9. 7. Tehran tube: specially designed for nasal intubation : Have a typical upper airway curve. : Reusable. : Made of silicon. : Can be inserted blindly.
- 10. 8. Laryngectomy Tube :Designed to be inserted through tracheostomy : J shaped. : To be made straight before intubation : No bevel end.
- 11. 8. Endotrol Tube: Has a trigger loop. : Pulling the trigger lead to decrease in inter radius of tube. : Facilitate blind nasal intubation. : For surgeries suspecting cervical spine injury
- 12. 9. EndoFlex® Tube :Almost same as endotrol tube. : Pulling the white bar causes tube tio to bend anteriorily. : Facilitates intubation in patient with anteriorly placed larynx
- 13. 10. Parker Flex-Tip®Tube : Hooded tip. : Flexible distal end. : Best to go with bronchoscope. : Available with or without Murphy's Eye.
- 14. 11. Electromyogram ReinforcedTracheal Tube : To monitor RLN electromyogram during surgery. : Wired reinforcement. : Four electrodes above cuff.
- 15. 12. Intubating LaryngealMask Tracheal Tube : Specially designed to be used with LMA. : Wire reinforced sicon tube. : Available in 6,6.5, 7 & 7.5 sizes. : Reusable. : Separately used in sub- mental intubation. : eccentric cuff inflation. : MRI Compatible.
- 16. 13. Hi-Lo Evac®Tube : Dedicated channel. : To facilitate suction during surgery. : Suction the are above cuff and below vocal cord. : Lumen may be blocked by secretion.
- 17. 14. Hi-Lo JetTube : Uncuffed tube with additional lumen. : Jet ventilation. : Monitoring airway pressure. : Sampling respiratory gases. : Administering LA. : Irrigating the airway. : Suction through main tube is difficult.
- 18. 15. Laser-Resistant Tubes 15.LASER Resistant tubes.
- 19. 16. Double LumenTubes : Used to isolate lung during CTVS surgeries : Prevents contamination of contralateral lung. : Achieve independent lung ventilation in unilateral parenchymal injury and bronchopulmonary fistula.
