Bilkul detailed! Chalo step-by-step poora procedure samjhate hain - RSI (Rapid Sequence Intubation) jo emergency mein sabse common aur best method hai.
Intubation - Exact Technique (RSI Method)
Emergency mein "Gold Standard" method
Pehle samjho: RSI kya hota hai?
RSI = Rapid Sequence Intubation
- Patient ko pehle sedation dete hain (so jaaye)
- Fir turant paralytic drug dete hain (muscles relax ho jaayein)
- Tab tube daalo - ye sab 60 seconds ke andar!
- Kyun? Taaki aspiration na ho aur intubating conditions best ho
Zaruri Equipment Pehle Check Karo β
β
Laryngoscope (light check karo - kaam kar raha hai?)
β
Endotracheal Tube (ETT) - cuff inflate/deflate karke check karo
β
Stylet (tube ke andar ka wire)
β
Syringe (cuff inflate karne ke liye - 10 mL)
β
Bag-Valve-Mask (BVM)
β
Suction machine - ON aur ready
β
End-tidal CO2 colorimeter / Capnography
β
IV line - do large bore lines
β
Cardiac monitor + pulse oximeter
β
Rescue airway backup (LMA, surgical airway kit)
RSI ke "6 Ps" - Yaad karo!
P1 - PREPARATION (0 minute)
- Sab equipment ready karo
- IV access confirm karo
- Monitor lagao
- ETT size choose karo:
- Adult male: 8.0 mm tube, 22 cm tak daalo
- Adult female: 7.5 mm tube, 21 cm tak daalo
- Cervical spine stabilize karo - trauma patient mein inline stabilization
P2 - PREOXYGENATION (0-3 minutes)
- 100% O2 do - BVM se ya tight-fit mask se
- 3-5 minutes ya jab tak SpO2 > 95% ho
- Nasal cannula bhi lagao - 10-15 L/min (apneic oxygenation ke liye)
- Kyun? Tube daalne mein time lagta hai - patient ko reserve chahiye
π‘ Obese/pregnant patient mein shoulder roll ya ramp lagao - neck thodi upper ho
P3 - PREMEDICATION (3 minutes pehle)
Ye optional adjuncts hain - case ke hisab se:
| Drug | Dose | Kab dete hain |
|---|
| Lidocaine | 1.5 mg/kg IV | Raised ICP ya bronchospasm mein |
| Atropine | 0.02 mg/kg IV (min 0.1 mg) | Bacchon mein (<10 yrs) - bradycardia rokne ke liye |
| Fentanyl | 1-3 mcg/kg | Hemodynamically stable patients mein ICP control |
P4 - PARALYSIS with Induction (3-5 minute mark)
Step 1 - Sedation/Induction agent pehle do:
| Drug | Dose | Kab best hai |
|---|
| Etomidate | 0.3 mg/kg IV | Most common choice - BP pe asar nahi padta |
| Ketamine | 1-2 mg/kg IV | Bronchospasm, hypotension (BP gira ho) |
| Midazolam | 0.2 mg/kg IV | Alternate option |
| Propofol | 1-2 mg/kg IV | Hemodynamically stable patients |
β οΈ TBI mein Ketamine avoid karo - agitation bada sakta hai
Step 2 - Turant Paralytic do (Induction ke baad immediately):
| Drug | Dose | Notes |
|---|
| Succinylcholine | 1.5-2 mg/kg IV | First choice - 60 sec mein kaam karta hai, 10-15 min rehta hai |
| Rocuronium | 0.8-1.2 mg/kg IV | Agar Succinylcholine contraindicated ho |
Succinylcholine KABHI mat do agar:
- Burns (24 hr se zyada purane)
- Crush injury
- Hyperkalemia
- Neuromuscular disease (Myasthenia, Muscular Dystrophy)
- Open globe injury
P5 - PLACEMENT of Tube
60 seconds mein karo! Paralysis complete ho jaati hai.
Step 1 - Position
Patient ko "Sniffing Position" mein rakho:
- Neck thoda flex (chin upar)
- Head extend (aise jaise koi smell soongh raha ho)
- Chin aur chest ke beech "sniffing the morning air" wali position
Step 2 - Muh Kholo
- Right hand se muh kholo
- Laryngoscope left hand mein lo
Step 3 - Blade Daalo
- Laryngoscope blade right side se daalo - tongue ko left mein sweep karo
- Macintosh blade (curved): tip ko vallecula mein daalo (tongue aur epiglottis ke beech)
- Miller blade (straight): directly epiglottis utha lo
Step 4 - Lift Karo
- Laryngoscope ko upar ki taraf lift karo - tilt mat karo! (handle ki direction mein force lagao)
- Vocal cords dikhni chahiye - do white/yellow bands dikh rahe honge
Step 5 - Tube Daalo
- Vocal cords dikh rahe hain? Tab hi tube daalo
- Cuff vocal cords se thoda neeche chali jaaye
- Stylet nikal lo (tube cords ke baar ho jaaye tab)
- Inflate karo cuff - 5-10 mL air syringe se
Step 6 - Depth set karo
- Males: 22 cm at gum/teeth
- Females: 21 cm at gum/teeth
- Tube ko bahar se pakad ke secure karo
P6 - POST-INTUBATION Management (Confirm + Secure)
Tube position confirm karna MUST hai - teen tarike se:
| Method | Kya dekhte hain |
|---|
| 1. End-tidal CO2 (Colorimeter/Capnography) | Color change (purpleβyellow) = trachea mein hai β
|
| 2. Auscultation | Dono lungs mein breath sounds sun-no, pet pe nahi |
| 3. Chest X-ray | Final confirm + depth check |
β οΈ Agar pet pe awaz aaye aur chest pe nahi - ESOPHAGEAL INTUBATION ho gayi! Turant nikalo!
Tube confirm ho gaaye tab:
- Tape se secure karo
- Sedation continue karo (patient hosh mein aa jaayega!)
- Ventilator settings lagao
- Serial GCS monitor karte raho
Failed Intubation - Kya karte hain?
Attempt 1 fail β Reposition karo, Suction karo
Attempt 2 fail β Help bulao (senior/anesthesia)
Still fail β LMA (Laryngeal Mask Airway) lagao
LMA bhi fail β Surgical Airway - Cricothyrotomy!
Maximum 3 attempts karo - zyada karne se trachea traumatize ho jaati hai
Ek Line Mein Summary
Position β Preoxygenate β Drug do (Etomidate + Succinylcholine) β Laryngoscope β Cords dekho β Tube daalo β Confirm karo
