Central Line Insertion Complications

The podcast addresses complications associated with central venous catheterization, particularly concerning the training of new interns. Risk factors such as inexperience, number of needle passes, patient body habitus, dehydration, and prior catheterizations are discussed. While coagulopathies don't necessarily increase risk if precautions are taken, unsuccessful insertion attempts are strong predictors of complications. Femoral catheterization has a surprisingly high mechanical complication rate compared to subclavian and IJ access. The use of ultrasound-assisted insertion is highlighted as a significant safety measure. Other complications discussed include pneumothorax, catheter malpositioning, arterial injury, arrhythmias, and guide wire embolization. The podcast also answers a listener question about managing peak inspiratory pressure in a patient with a small endotracheal tube, explaining the interplay between tidal volume, lung compliance, and airway resistance.
