While the medically-induced coma helped did help for a few hours, ICP rose again early this morning. Another CAT scan (his fourth) revealed increased swelling in the temporal lobe. His Neuro-surgeon installed a Ventricular Catheter to releive the pressure. This is a catheter into the brain to drain brain fluid. This therapy has brought his ICP down below 20 again.

He has also developed some problems with Diabetes insipidus, meaning that his kidneys are not retaining enough water. So, too much water is excreted in urine and the sodium levels rise in the blood. His medical team is responding by actively pumping more fluids into him.
