Trauma & Emergency Surgery** - **Head Injury (Concussion, Contusion, Hematomas)** - **Diagnosis**: Glasgow Coma Scale (GCS), CT Brain - **Treatment**: **ICP management, Craniotomy (if required)** - **Chest Trauma (Pneumothorax, Hemothorax, Flail Chest)** - **Diagnosis**: CXR, Clinical signs (Hyperresonance in Pneumothorax) - **Treatment**: **Chest tube drainage** - **Abdominal Trauma** - **Diagnosis**: FAST (Focused Abdominal Sonography for Trauma), CT Abdomen - **Treatment**: **Surgical exploration (Laparotomy)** - **Burns & Fluid Resuscitation** - **Rule of 9s (TBSA calculation)** - **Parkland Formula (Fluids = 4ml × kg × % burn, 50% in 8 hours)** - **Treatment**: IV Fluids, Pain management, Debridement --- #### **C. Surgical Oncology** - **Breast Cancer** - **Diagnosis**: Mammography, FNAC/Biopsy - **Treatment**: **Modified Radical Mastectomy (MRM), Chemotherapy** - **Thyroid Cancer & Goiter** - **Diagnosis**: USG, FNAC, Thyroid Function Tests - **Treatment**: **Thyroidectomy (Partial/Total)** --- #### **D. Vascular Surgery** - **Varicose Veins** - **Diagnosis**: Doppler USG - **Treatment**: **Sclerotherapy, Vein stripping, Laser ablation** - **Deep Vein Thrombosis (DVT)** - **Diagnosis**: Doppler USG, D-dimer - **Treatment**: **Anticoagulants (Heparin, Warfarin), Compression stockings** --- #### **E. Urological Surgery** - **Urinary Stones (Renal, Ureteric, Bladder Stones)** - **Diagnosis**: USG KUB, IVP, CT Scan - **Treatment**: **ESWL (Lithotripsy), PCNL, Ureteroscopy** - **Prostate Enlargement (BPH, Prostate Cancer)** - **Diagnosis**: PSA test, Digital Rectal Exam - **Treatment**: **TURP (Transurethral Resection of the Prostate), Surgery** --- ## **Common Surgical Procedures & Techniques** - **Suturing Techniques** (Simple interrupted, Mattress, Subcuticular) - **Incisions** (Midline, Kocher’s, McBurney’s, Pfannenstiel) - **Laparoscopic vs Open Surgery** (Advantages & Disadvantages) - **Types of Biopsy** (Excisional, Incisional, FNAC, Core Needle) --- ## **Study Tips for General Surgery** ✅ **Use mnemonics** (e.g., **"LIMP" for Hernia complications – Loss of domain, Infection, Mesh rejection, Pain**) ✅ **Practice clinical case scenarios** for better understanding ✅ **Watch surgical videos (YouTube, Medscape)** to visualize procedures ✅ **Refer to Bailey & Love’s Short Practice of Surgery** ---

Xrays

 No one knows the long-term effects of ultrasound use. Many practitioners feel that the technology is perfectly safe since studies of babies and their mothers have not determined any effects. Other practitioners are not so convinced of ultrasound safety and feel that judicious use is advised. Keep in mind that x-rays were in use for fifty years before the general public became aware of their negative effects. DES and thalidomide were initially thought to be safe, but it was later discovered that they were the root of cancer, sterility, and anomalies. The greatest risk of using ultrasound technology too much is that if an ultrasound raises a question about the health of the fetus, invasive and high-risk procedures and technologies may be used, which do carry obvious risks for the mother or her child. STUDIES Non-diagnostic ultrasound has demonstrated b8iological effects such as cell heating or thermal effects and cavitational activities using plants and animals. It is difficult to c...
