- IV Catheter: Fluid/medication/blood product delivery via vein access.
- Arterial Catheter: Continuous BP monitoring, blood sampling in pressure-critical procedures.
- Central Venous Catheter: Complex/prolonged surgeries; large-vein access for fluids/meds.
- NG/OP Tube: GI surgeries/aspiration risk; gastric decompression, nutrition support.
- Lumbar Epidural Catheter: Postoperative pain management via anesthetic delivery.
- Biliary Catheter: Gallbladder/bile duct surgery; drains bile, relieves obstruction.
- Thoracic Catheter: Pleural effusion/pneumothorax; drains air/fluid, restores lung function.
- Dialysis Catheter: Renal replacement therapy during surgery; enables hemodialysis.
Selection depends on procedure type, patient condition, and surgeon judgment—ensuring safe fluid/medication administration and drainage.
