[Verse 1] Picture a dial, not a switch, not a cliff — Sedation's a spectrum, a graduated drift Minimal, moderate, deep, then general's door Each rung on the ladder demands something more Minimal — anxiolysis, you respond to my call Moderate — purposeful, airway stands tall Deep sedation, repeated stimulation required General — unconscious, all reflexes retired The ASA carved these definitions in stone So every practitioner speaks in the same tone Because the patient who slips past your target zone Can obstruct or apnea when left alone [Chorus] P-M-D-K-R — five drugs in your hand Propofol, Midazolam, Dex, Ketamine, Remimazolam Monitor the capnograph, the pulse ox, the pressure Oversedation's a thief that steals at leisure Know the continuum, know where you stand Sedation is science, not sleight of hand [Verse 2] Propofol moves fast — context-sensitive, clean Titrate by the syringe, watch the apnea convene Midazolam's the prelude, anxiolytic and mild Flumazenil reverses if the dosing ran wild Dexmedetomidine — an alpha-two agonist, precise Cooperative sedation, keeps the airway in service Arousable, analgesic, hemodynamically priced Bradycardia's the toll — know the balance sufficed Ketamine dissociates — a phencyclidine kin Preserves the airway, keeps the drive breathing in Bronchodilation, analgesia, sympathomimetic surge Emergence phenomena lurk at the procedure's verge Remimazolam — benzodiazepine by ester design Metabolized by tissue esterases, bypassing the renal line Flumazenil reverses it, short-acting and defined A newer card dealt from the sedation hand [Chorus] P-M-D-K-R — five drugs in your hand Propofol, Midazolam, Dex, Ketamine, Remimazolam Monitor the capnograph, the pulse ox, the pressure Oversedation's a thief that steals at leisure Know the continuum, know where you stand Sedation is science, not sleight of hand [Bridge] Here's where the anesthesiologist earns their place — Non-anesthesiologists sedate in endoscopy's space Gastroenterology, radiology, the cardiac suite They need oversight protocols, rescue skills complete Capnography catches the apnea before desaturation blooms A minute of warning before hypoxia consumes the room The mordant truth of monitored anesthesia care: The deepest risk is the sedation nobody labeled as there MAC isn't minimal — it can touch the general plane Assign an anesthesia provider, document the chain Airway assessment first: Mallampati, neck, the jaw Because the patient who deteriorates deserves no pause [Verse 3] Monitor the standard: ECG, the non-invasive cuff Pulse oximetry, temperature when the procedure's rough Capnography — end-tidal carbon dioxide's the voice That tells you breathing's failing before cyanosis makes the noise Supplemental oxygen — a double-edged reprieve It masks the desaturation that the capnograph perceives So trust the waveform, trust the number on the screen Titrate to effect, and watch the whole machine
