Is Preoperative Endothelial Dysfunction a Potentially Modifiable Risk Factor for Renal Injury Associated With Noncardiac Surgery?

Objectives: To determine whether preoperative endothelial dysfunction provides risk stratification for perioperative renal injury in patients undergoing noncardiac surgery. The relationship between perioperative renal injury and myocardial injury after noncardiac surgery (MINS) was explored secondarily.

Design: An observational study.

Effect of nitrous oxide anesthesia on plasma homocysteine and endothelial function.

Background: Endothelial function is impaired with hyperhomocysteinemia. Plasma homocysteine is increased by nitrous oxide anesthesia. The current study was designed to determine whether endothelial function is impaired after surgery and whether this is made worse by exposure to nitrous oxide.

Neuropathic pain and foot drop related to nerve injury after short duration surgery and caudal analgesia.

Caudal anesthesia is the most common type of regional anesthetic technique performed in children. The incidence of neurologic adverse events is extremely rare. A postoperative complication of a mild but permanent neurologic deficit after administration of a caudal anesthetic in a previously well 9-year-old boy who required emergency scrotal exploration for a testicular torsion is reported.
