|---|---|---|
| 1 | THRIVE | Mechanism (apneic oxygenation + CO₂ flushing), 60 L/min, applications in difficult airway/bariatrics/ENT |
| 2 | CDH | Pulmonary hypoplasia + PH, avoid BVM/N₂O, permissive hypercapnia, pre/post-ductal monitoring, ECMO |
| 3 | Bariatric | Ramped position, TIVA/desflurane, IBW vs TBW dosing, sugammadex, ERAS, DVT risk |
| 4 | Bronchial Blockers | Types (Arndt/Cohen/EZ), indications, fiberoptic guidance; Diastolic Dysfunction — maintain SR, HR 60–80, avoid tachycardia |
| 5 | Spinal Additives | Morphine/fentanyl/clonidine/adrenaline; PDPH: needle gauge, type (Whitacre < Quincke), bevel orientation; complications: TNS, cauda equina, hematoma |
| 6 | Neurotoxicity | NMDA/GABA-A mechanisms, FDA 2016 warning, GAS trial, defer elective surgery <3 yrs; Autonomic Dysreflexia: T6 level, SBP >200, triggers, phentolamine |
