Randomized Controlled Trial Comparative Study
A comparative study of the antiemetic efficacy of dexamethasone, ondansetron, and metoclopramide in patients undergoing gynecological surgery.
Postoperative nausea and vomiting (PONV) are some of the most-common and undesirable adverse effects after surgery performed under general anesthesia. We investigated the prophylactic value of dexamethasone as an alternate to ondansetron or metoclopramide to prevent PONV after gynecologic surgery. ⋯ Prophylactic IV dexamethasone 8 mg significantly reduces the incidence of PONV in gynecologic surgery. At this dosage, dexamethasone is as effective as ondansetron 4 mg and metoclopramide 10 mg, and is more-effective than placebo.

The accidental migration of air from the venous circulation into the systemic arterial circulation is called paradoxical air embolism. This is a potential disastrous complication after diagnostic and surgical procedures. Arthrography has been a useful technique in joint imaging for the past decades. Paradoxical cerebral air embolism is a very rare complication, only a few cases have been reported after arthrography of the hip in children. Here, we describe a patient with progressive encephalopathy after computer tomography (CT) arthrography of the ankle. ⋯ This case of paradoxical air embolism with severe neurological manifestations after arthrography of the ankle, emphasizes that air embolism should be considered in all patients with neurologic and/or hemodynamic deterioration after the injection of intra articular air. Furthermore a delay of more then 6 hours is no reason to withhold HBO in these patients.

S100B is a prominent cell damage marker which can lead to sustained pro-inflammatory signaling. The aim was to investigate cross-sectional associations of steady-state S100B concentrations, particularly with C-reactive protein (CRP), in renal transplant recipients (RTRs) and also to investigate prospectively whether S100B would predict graft failure or mortality. ⋯ BMI, creatinine clearance, and age are determinants of steady-state serum S100B concentrations in renal transplant recipients. The association of BMI with S100B suggests that S100B might be a new adipokine.
