🧵 Types of Surgical Sutures – Quick Guide for Clinical Practice

Choosing the right suture is key to optimal wound healing. From absorbable vs non-absorbable to monofilament vs multifilament, understanding their properties helps ensure strength, minimal infection risk, and proper tissue support.

✔️ Absorbable – Ideal for internal tissues
✔️ Non-absorbable – Great for skin & long-term support
✔️ Monofilament – Less tissue reaction
✔️ Multifilament – Better knot security
✔️ USP sizes – From 10-0 (fine) to 7 (thick)

📊 Understanding ETCO₂ – A Must-Know for Nurses!

ETCO₂ (End-Tidal Carbon Dioxide) measures the amount of CO₂ exhaled at the end of expiration — giving real-time insight into ventilation and perfusion.

🔎 What it tells you:
✔️ How well your patient is ventilating
✔️ Perfusion status
✔️ Circulation & even cardiac output

🚨 Abnormal values?
🔴 High ETCO₂ → Hypoventilation, CO₂ retention
🔵 Low ETCO₂ → Hyperventilation, Poor perfusion, Cardiac arrest

Capnography isn’t just a number — it’s an early warning tool.

Sleep apnea is a common sleep disorder characterized by repeated pauses in breathing or shallow breathing during sleep. These interruptions can last from a few seconds to over a minute and may occur dozens or even hundreds of times per night. The most common type, obstructive sleep apnea (OSA), occurs when the muscles in the throat relax and block the airway. Central sleep apnea is less common and results from the brain failing to send proper signals to the breathing muscles. Another form, complex sleep apnea, is a combination of both types.

Sleep apnea often causes loud snoring, gasping for air during sleep, excessive daytime sleepiness, headaches, irritability, and difficulty concentrating. If left untreated, it can increase the risk of serious health problems such as high blood pressure, heart disease, stroke, and diabetes. Treatment options may include lifestyle changes, continuous positive airway pressure (CPAP) therapy, oral appliances, or surgical procedures.

🚑 EMERGENCY TRIAGE — Know Your Priorities!

In critical situations, fast and accurate triage saves lives.

🔴 Red – Immediate (Treat NOW)
🟡 Yellow – Delayed (Serious but stable)
🟢 Green – Minor (Walking wounded)
⚫ Black – Expectant/Deceased

Remember:
👉 Airway, Breathing, Circulation always come first.
👉 The sickest patient is NOT always the loudest one.

The classic triad every nurse must know:

🔺 Respiratory depression
🔺 CNS depression
🔺 Pinpoint pupils

If the patient isn’t breathing properly, nothing else matters.
👉 Airway and breathing come FIRST.

💉 Naloxone (Narcan) can reverse opioid effects — but remember:
⚠️ It wears off before many opioids do.
⚠️ Re-sedation is common.
⚠️ Continuous monitoring is essential.

🛑 Call Rapid Response if:
• RR < 8
• SpO₂ < 90%
• Unarousable
• Apnea or cyanosis

🧠 Clinical Pearl:
Respiratory depression kills first — early recognition saves lives.

Cardio pearls you should never miss

🔴 1️⃣ Wide QRS tachycardia in age >35?
Treat as VT unless proven otherwise. Don’t fall for “SVT with aberrancy.”

🔴 2️⃣ Inferior MI + hypotension + clear lungs?
Think RV infarct. Give fluids, NOT nitrates.

🔴 3️⃣ New systolic murmur 3–5 days after MI?
Think papillary muscle rupture 👉🏻acute MR.

🔴 4️⃣ Sudden hypotension + JVP rise + muffled sounds post-MI?
Free wall rupture 👉🏻 Tamponade.

🔴 5️⃣ Atrial fibrillation + instability?
Immediate synchronized cardioversion. Don’t waste time with rate control.

🔴 6️⃣ Chest pain better on leaning forward + diffuse ST elevation + PR depression?
Acute pericarditis, not STEMI.

🔴 7️⃣ Syncope during exertion in young athlete?
Think HOCM first.

🔴 8️⃣ LBBB + chest pain?
Use modified Sgarbossa criteria, don’t ignore MI.

🔴 9️⃣ Hypertension + hypokalemia?
Primary hyperaldosteronism until proven otherwise.

🔴 🔟 Post-MI day 2–3 fever + pericardial rub?
Early fibrinous pericarditis (not Dressler that’s weeks later)

Save this. Share it.

🩺 Know Your Numbers!

Blood pressure tells us how hard your heart is working.
Normal isn’t the same for everyone — but uncontrolled BP can damage your heart, brain, and kidneys silently.

✔️ Check it regularly
✔️ Control salt intake
✔️ Stay active
✔️ Take medications as prescribed

Emphysema is marked by the destruction of alveolar walls, leading to air trapping, hyperinflation, and progressive shortness of breath with minimal mucus production. Chronic bronchitis, on the other hand, involves persistent airway inflammation and excessive mucus secretion, causing a chronic productive cough and frequent respiratory infections.
