Now I have everything I need to give you a complete, well-organized answer. Here it is:

Your Notes - Decoded and Explained

What Your Notes Are About

Your three photos together describe a case presentation on Awake Fiberoptic Intubation (AFOI) in a patient with a mediastinal mass causing tracheal compression. This is a classic anesthesia/difficult airway case. Here's a full breakdown:

1. The Presentation Structure (Poster Layout)

Your notes sketch out the layout of a case report/conference poster with these sections:

Section	Content
Title	(your case title)
Author (1, 2, 3)	Author names
Introduction	Background on the condition
Case Presentation	The actual patient case
Discussion	Why this approach was chosen
Conclusion	Key takeaway
Reference	Citations

2. The Case - What the Patient Had

Pre-op workup noted:

Pre-op X-ray (CXR) - chest X-ray done before surgery
Fiberoptic / V.C. (vocal cord) check - assessed vocal cord movement
Intubated - patient needed intubation
Mass (4th) - likely a 4th-compartment / anterior mediastinal mass
CT scan slide - CT chest was done

This is the typical presentation: A patient with a mediastinal mass compressing the trachea, making normal general anesthesia + paralysis dangerous. The trachea could collapse completely once muscle tone is lost.

Here is what such imaging typically looks like (CXR on left, CT on right showing tracheal/carinal compression):

Mediastinal mass with tracheal compression - CXR and CT

3. The Images to Include in the Presentation

From the whiteboard notes:

#	Image	Notes
1	CXR (Pre-op)	Mandatory
2	HRCT - compressed trachea slide	Mandatory - shows the compression
3	Mass (CT/image showing the mass)	Mandatory
4	Intubated patient image	Optional
5	Fiberoptic image while intubating	Optional

4. The Awake Fiberoptic Intubation Technique (Your Main Notes)

Your handwritten notes on the right side describe the step-by-step AFOI protocol:

Step 1 - Topical Airway Anesthesia

LOX 4% Nebulization: 2 mL + 2 mL NS

LOX = Lignocaine (Lidocaine) 4%
Diluted with normal saline and given via nebulizer mask
The patient inhales it for 10-15 minutes
This numbs the pharynx, larynx, and upper trachea so the scope can pass without triggering violent coughing/gagging
From the textbook: "5 mL of 2% plain lidocaine can be inhaled via nebulizer" - your case uses 4% which gives more concentrated topical effect (- Cummings Otolaryngology)

Step 2 - Transtracheal Block

Transtracheal block → Inj. LOX 2% 2 mL + Inj. Bupivacaine 2 mL

A needle is passed through the cricothyroid membrane into the trachea
Lignocaine 2% (2 mL) + Bupivacaine 2% (2 mL) injected directly
Patient coughs reflexively - this sprays the drug upward onto the cords and downward into the trachea, anesthetizing both
This is the cricotracheal (transtracheal) block
Together with the nebulization, this achieves full topical anesthesia of the entire airway from pharynx to carina

Step 3 - Fiberoptic Intubation

Fiberoptic intubation (after full airway anesthesia)

The flexible fiberoptic bronchoscope is passed through the endotracheal tube (ETT), guided through the vocal cords under direct vision, and advanced into the trachea
The ETT is then railroaded over the scope
Patient remains awake and breathing spontaneously throughout - this is the safety net; if the airway collapses, the patient's own respiratory effort helps maintain patency

5. The Flowchart at the Bottom of Your Notes

After seeing airway → Inj. (?) → (10 sec) → (Rocuronium) → Crisis

This appears to be a note about what NOT to do, or a failed/dangerous sequence - the "Crisis" at the end is a warning. It likely refers to:

A scenario where, after confirming the airway on fiberoptic view, someone prematurely gives Rocuronium (a neuromuscular blocker/paralytic)
In 10 seconds, full paralysis sets in
With a compressing mediastinal mass, the trachea now collapses because all muscle tone is gone
Result: Cannot ventilate, cannot intubate - crisis / cannot oxygenate situation

This is exactly why the awake technique is used - you never paralyze first in a compressed trachea case. Miller's Anesthesia states: "If muscle relaxants are required, ventilation should first be gradually taken over manually to assure that positive-pressure ventilation is possible and only then can a [relaxant] be given."

6. Why Awake Intubation is Chosen Here (the Discussion angle)

General anesthesia + paralysis is dangerous in mediastinal mass with tracheal compression for 3 reasons (per Miller's Anesthesia, 10e):

Reduced lung volume under GA shrinks tracheal diameter
Bronchial smooth muscle relaxes - airway becomes more compressible
Paralysis removes spontaneous breathing - eliminates the negative intrathoracic pressure that normally keeps airways open

So the anesthesiologist chose AFOI - the patient breathes spontaneously, airway tone is maintained, and intubation is done safely under direct vision.

7. What You Need to Do for the Presentation

Based on all three notes, here is your to-do list:

Collect the images: CXR pre-op, HRCT showing compressed trachea (key slide), mass image - these 3 are mandatory
Write the case: Age/sex, presenting complaint, workup findings (CXR + HRCT), the mass, and the anesthetic challenge
Describe the technique: Nebulized Lignocaine 4% (2 mL + 2 mL NS) → Transtracheal block (LOX 2% 2 mL + Bupivacaine 2 mL) → Fiberoptic intubation
Discussion: Why AFOI was chosen - explain the danger of GA + paralysis in tracheal compression
Add optional images if you have them: photo of the intubated patient, fiberoptic view during intubation
Add the "crisis" flowchart as a teaching point in the discussion - what would have happened if paralysis was given first
Slide structure: Follow the poster layout - Title → Author → Introduction → Case Presentation → Discussion → Conclusion → Reference

The presentation is essentially a case report of a difficult airway successfully managed with awake fiberoptic intubation in a patient with a mediastinal mass - a high-value anesthesia teaching case.

I want to do a poster presentation on this case. Please do help me on this from the anesthesia side.

Asking for Preferences

Go ahead and type out your patient details - I need:

Patient - age, sex
Chief complaint - what brought them in (e.g., breathlessness, stridor, neck swelling?)
Mass - what it was (e.g., anterior mediastinal mass, thyroid mass, lymphoma, thymoma?) and any size if known
Tracheal compression - how much? (e.g., >50% on CT, just HRCT showed compression?)
Any co-morbidities (e.g., hypertension, diabetes, etc.) or was the patient otherwise healthy?
What surgery was done - why did they need intubation? (biopsy, excision, VATS?)
Your name and co-authors / institution name for the poster title

Type out whatever you have - even rough notes are fine, I'll structure everything.

drains removed | | **POD-5/6** | 21-22 Jun | Pain managed; ambulating; discharge planning | ### Post-Op Complications (managed successfully) 1. **Right-sided pneumothorax** (POD-2) - resolved with drain management 2. **Right pleural effusion with consolidation** (POD-2) - resolved within hours 3. **Small left minimal pleural effusion** (POD-3) - resolved spontaneously by POD-4 4. **Post-op anaemia** (Hb dropped from 11.9 → 9.8 g/dL) - managed with blood transfusion 5. **Hypoalbuminaemia** (Albumin dropped 3.9 → 2.6 g/dL post-op) - expected post-surgical acute-phase response, managed with nutrition --- ## HISTOPATHOLOGY REPORT **Report No.:** 1917/26 | **Date Reported:** 22 June 2026 ### Microscopic Findings: - **Multiple tissue types from all three germ layers** (confirms teratoma) - **Ectoderm:** Stratified squamous epithelium, sebaceous glands, keratin flakes, hair follicles - **Endoderm:** Mucinous epithelium with goblet cells, pseudostratified ciliated columnar epithelium (respiratory-type lining), well-formed glands with papillary structures - **Mesoderm:** Adipose (fat) tissue, fibrous stroma, cartilage, nerves - Chronic haemorrhage with hemosiderin-laden macrophages (old bleeding within the tumour) - Dense lymphocytic and plasma cell infiltrate - Cholesterol clefts - **No immature (malignant) elements identified** ### Final Diagnosis: # ✅ MATURE CYSTIC TERATOMA - Mediastinal Mass (BENIGN) --- ## DISCUSSION POINTS ### What is a Mediastinal Mature Cystic Teratoma? - A **germ cell tumour** arising from primordial germ cells in the anterior mediastinum - Contains derivatives of all 3 embryonic germ layers (hence "mature") - "Cystic" - forms fluid-filled cavities with cheesy/sebaceous content and hair - **Most common primary germ cell tumour of the mediastinum** - Predominantly occurs in **young adults (20-40 years)**, more common in females - Accounts for ~10-15% of all anterior mediastinal masses ("4 T's" = Thymoma, Teratoma, Terrible lymphoma, Thyroid) ### Why anterior mediastinum? - Primordial germ cells migrate from the yolk sac during embryogenesis; aberrant migration leads to extragonadal germ cell tumours at midline structures including the anterior mediastinum ### Classic CT Triad (seen in this case) 1. **Fat** (adipose tissue within the mass) 2. **Calcification** 3. **Soft tissue components** - This triad on CT is **pathognomonic (diagnostic)** of mature cystic teratoma ### Why surgery? - Teratomas grow progressively - Risk of **rupture** causing chemical mediastinitis or pericarditis - Can cause compression of trachea (as seen here - tracheal deviation), SVC, heart - Risk of **malignant transformation** (~1-3%) if left untreated - Complete surgical excision is **curative** ### Why was thyroid function (TSH) checked? - Anterior neck swelling can be due to a **substernal goitre** (enlarged thyroid extending into chest). Normal TSH + CT findings ruled this out. ### Why was NT-proBNP and Troponin checked? - The large mediastinal mass was adjacent to the heart and great vessels. These cardiac markers ruled out **cardiac compression, tamponade, or myocardial involvement** - essential before major thoracic surgery. --- ## KEY LEARNING POINTS 1. **Mediastinal teratomas present in young women** with anterior neck/chest swelling - often long-standing and slow-growing 2. **CT chest with contrast** is the gold standard investigation - fat + calcification + soft tissue = diagnostic triad 3. **Tracheal deviation** on CXR is a red flag indicating significant mass effect from a large mediastinal tumour 4. **Pre-operative workup** must include: CBC, coagulation, LFT, KFT, thyroid function, cardiac markers (NT-proBNP, Troponin), ECG, and infectious disease screening 5. **Median sternotomy** is the preferred surgical approach for anterior mediastinal tumours 6. Post-operatively, **pneumothorax and pleural effusion** are expected complications of thoracic surgery - managed with chest drains 7. **Histopathology is essential** - "mature" vs "immature" teratoma has major prognostic implications: - Mature = benign, surgery curative - Immature = malignant potential, needs chemotherapy/radiotherapy 8. **Hypoalbuminaemia** post major surgery is expected and reflects the acute inflammatory response + fluid shifts, not liver disease 9. This patient achieved **same-day extubation** and **complete lung recovery by POD-4** - reflecting excellent surgical and anaesthetic management 10. **Ayushman Bharat scheme** allowed this major complex surgery to be performed on a young patient from a lower-income background at no out-of-pocket cost --- ## OUTCOME - ✅ Complete surgical excision achieved - ✅ Histopathology: **Benign (Mature Cystic Teratoma)** - ✅ No malignant elements - **No adjuvant therapy required** - ✅ Post-op complications resolved by POD-4 - ✅ Discharged with follow-up appointment - **Prognosis: Excellent - Surgery is curative for mature cystic teratoma**Here is a complete, well-structured case presentation of Mrs. Roshani Sen, ready to present: --- # CASE PRESENTATION ## Anterior Mediastinal Mature Cystic Teratoma --- ## PATIENT PROFILE - **Name:** Mrs. Roshani Sen - **Age:** 26 years 10 months - **Sex:** Female - **DOB:** 05 August 1999 - **Address:** Gunjali, Sanawad, Madhya Pradesh - **Admission Date:** 09 June 2026 - **Hospital:** Parul Sevashram Hospital, Vadodara (CTVS Unit) - **Consultants:** Dr. Dipesh D.

AFOI Mediastinal Teratoma Poster

Presentation · PPTX

What's in the poster

Format: Single-slide A0 landscape (33 × 23 inches) - standard conference poster size. Three-column layout with navy + teal + orange colour scheme, suitable for PG/resident level.

Column 1 — Background & Case

Introduction: what AMMs are, the "4 T's", and why tracheal compression is an anaesthetic crisis
Patient profile: Mrs. Roshani Sen, 26F, her complaint, vitals, SpO₂ 94%
Pre-op investigations: CT findings (8.3 × 5.1 × 12.2 cm mass), CXR (tracheal deviation flagged in orange as a red flag), ECG, bloods

Column 2 — Anaesthesia (the main focus)

Pre-op airway assessment checklist (why AFOI was chosen)
Step-by-step AFOI protocol in full detail:
- Glycopyrrolate 0.2 mg IV (antisialagogue)
- Nebulised Lignocaine 4% (2 mL + 2 mL NS)
- Transtracheal block (Lignocaine 2% 2 mL + Bupivacaine 0.5% 2 mL through cricothyroid)
- Conscious sedation (Midazolam + Fentanyl / Dexmedetomidine)
- Fiberoptic bronchoscope guided intubation (ETT 7.5, railroaded over scope)
- GA + Rocuronium only AFTER ETCO₂ confirmed (with a bold orange warning never to paralyse first)
Intraoperative monitoring: CVC, ABG, ETCO₂, same-day extubation at 15:30

Column 3 — Surgery, Path, Recovery, Discussion, Conclusion

Median sternotomy, specimen details
Histopath: all 3 germ layers, NO immature elements → Benign
Post-op course day by day (complications + resolution)
Discussion: why AFOI is mandatory, mature vs immature teratoma
Conclusion: 5 green-highlighted takeaways

Footer: Hospital name, department, references (Miller's Anesthesia 10e, Cummings Otolaryngology, Barash Clinical Anesthesia 9e)

Tip for printing: When you open it in PowerPoint, go to Design → Slide Size → Custom → set to 33.1 × 23.4 inches (A0) before sending to the printer. You can also scale it down to A1 (23.4 × 16.5 in) if that's what your venue requires.
