OBJECTIVES Premedication with clonidine has been found to reduce the bleeding during endoscopic sinus surgery (ESS), therefore lowering the risk of surgical complications. Premedication is an essential part of pre-surgical care and can potentially affect magnitude of systemic stress response to a surgical procedure. The aim of this study was to compare the efficacy of premedication with clonidi...

OBJECTIVE Surgical trauma impairs intraoperative insulin sensitivity and is associated with postoperative adverse events. Recently, preprocedural statin therapy is recommended for patients with coronary artery disease. However, statin therapy is reported to increase insulin resistance and the risk of new-onset diabetes. Thus, we investigated the association between preoperative statin therapy a...

The partial pressure of oxygen decreases as altitude increases, the preoperative chronic hypoxemia (CH) may have a plausible clinical impact. Risk factors for postoperative serious adverse events (pSAEs) in patients living in high altitudes during primary hip arthroplasty (HA) are not clear.This is an observational study embracing patients from January 1, 2011 to December 31, 2015 at Yan'an Hos...

Background. Periorbital basal cell carcinoma (BCC) is considered a high risk case because it is associated with high rate of recurrence and complication. Superpulsed CO2 laser with intraoperative pathologic assessment could be an alternative and appropriate treatment for periocular lesions where Mohs micrographic surgery is not available. Objective. To evaluate the efficacy of superpulsed CO2 l...

BACKGROUND Pressure ulcers represent a particularly difficult disease process and remain a financially important entity. The underlying bone in advanced ulcers may harbor osteomyelitis. Radiologic diagnosis of osteomyelitis is confounded by chronic pressure and shear. We sought to determine the test characteristics of preoperative magnetic resonance imaging (MRI) in the diagnosis of osteomyelit...

A vision of the future of intraoperative monitoring for anesthesia is presented-a multimodal world based on advanced sensing capabilities. I explore progress towards this vision, outlining the general nature of the anesthetist's monitoring task and the dangers of attentional capture. Research in attention indicates different kinds of attentional control, such as endogenous and exogenous orienti...
