Remifentanil induces autophagy and prevents hydrogen peroxide-induced apoptosis in Cos-7 cells.

Background: This study investigated the effect of remifentanil pretreatment on Cos-7 cells exposed to oxidative stress, and the influence of remifentanil on intracellular autophagy and apoptotic cell death.

Methods: Cells were divided into 4 groups: (1) Control: non-pretreated cells were incubated in normoxia (5% CO, 21% O, and 74% N). (2) HO: non-pretreated cells were exposed to HO for 24 h.

Damage to the pilot balloon of the nasotracheal tube during orthognathic double-jaw surgery: A case report.

In oral and maxillofacial surgery, many complications associated with nasotracheal tube can be caused. In this case, we reported ballooning tube damage of nasotracheal tube during orthognathic double-jaw surgery and replacement of tube through cut down of tube and tube exchange using airway exchange catheter. The patient scheduled for high Le Fort I osteotomy and bilateral sagittal split osteotomy was intubated nasotracheally with nasal endotracheal tube.

Acute mediastinitis secondary to delayed vascular injury by a central venous catheter and total parenteral nutrition.

Vascular injury caused by a central venous catheter (CVC) has been reported to be a rare complication, especially delayed vascular injury due to CVC has a few cases and it can be fatal because of delayed recognition and more serious complications. A 59-year-old woman with no available medical history was admitted for treatment of ovarian cancer. For the surgery, a triple-lumen CVC was placed through the left subclavian vein.
