Continuous thoracic epidural analgesia is a valuable and common technique for analgesia but involves risk to the spinal cord. There is significant pediatric experience safely placing thoracic epidurals via a caudal approach. The use of a stimulating catheter offers the advantage of real-time confirmation of appropriate catheter placement. We hypothesize that the tip of a stimulating epidural catheter can be reliably advanced to the thoracic epidural space with lumbar insertion in a porcine model. ⋯ Accurate access to the thoracic epidural space is possible via a lumbar approach using a stimulating epidural catheter. Based on gross and histopathological examination, this technique resulted in frequent complications, including subdural hemorrhage, deep spinal cord damage, and subarachnoid catheter placement.

Randomized Controlled Trial Comparative Study
Increase in intraocular pressure is less with propofol than with sevoflurane during laparoscopic surgery in the steep Trendelenburg position.
Intraocular pressure is increased during laparoscopic surgeries performed in a steep Trendelenburg position. This study compared the effects of propofol with those of sevoflurane on intraocular pressure in patients undergoing robot-assisted laparoscopic radical prostatectomy in a 30° Trendelenburg position. ⋯ Intraocular pressure increases after pneumoperitoneum and the steep Trendelenburg position are established. This increase is less with propofol than with sevoflurane anesthesia. This trial was registered at ClinicalTrials.gov: NCT01744262.

Aortic dissection is an infrequent but serious condition that often requires immediate operative intervention. We explore recent developments in the classification of aortic dissection and perioperative transesophageal echocardiography that assist with quantifying the severity of disease and facilitate its management. ⋯ Developments in the classification of aortic dissection have improved our perspective and understanding of the key presenting features that affect mortality. Improvements in patient outcome may be achieved in part by appropriately timed echocardiography-guided surgery.
