BACKGROUND The effectiveness of intraoperative povidone-iodine (PVI) application in the reduction of surgical-site infection (SSI) remains controversial. This meta-analysis was performed to assess the effect of intraoperative PVI application compared with no antiseptic solution (saline or nothing) on the SSI rate. METHODS The meta-analysis included randomized controlled trials that compared i...

BACKGROUND Respiratory variations in plethysmographic waveform amplitudes derived from pulse oximetry are believed to predict fluid responsiveness. The non-invasive pleth variability index (PVI) is a variable based on the calculation of changes in the perfusion index (PI). The aim of the following study was to examine whether the predictive power of PVI depends on different values of PI. METH...

Portal vein invasion (PVI) and extrahepatic spread (ES) are two tumor-related factors that define advanced stage in the Barcelona Clinic Liver Cancer (BCLC) staging system (BCLC stage C), and the recommended first line therapy in this stage is sorafenib. However, the extent of PVI and the type of ES may affect patient prognosis as well as treatment outcome. This study analyzed survival of BCLC ...

BACKGROUND Respiratory variations in pulse oximetry plethysmographic waveform amplitude (DeltaPOP) can predict fluid responsiveness in mechanically ventilated patients but cannot be easily assessed at the bedside. Pleth variability index (PVI) is a new algorithm allowing for automated and continuous monitoring of DeltaPOP. We hypothesized that PVI can predict fluid responsiveness in mechanicall...

BACKGROUND Pulmonary vein isolation (PVI) for atrial fibrillation (AF) is performed with the endoscopically assisted laser balloon ablation system (EAS). We hypothesized that placement of a circular mapping catheter (CMC) in the pulmonary vein (PV) distal to the laser balloon during ablation is feasible and safe. METHODS Out of 58 included patients, 37 underwent mapping-guided EAS PVI, with t...

BACKGROUND Fluid responsiveness is a measure of preload dependence and is defined as an increase in cardiac output due to volume expansion. Recent publications have suggested that variation in amplitude of the pulse oximetry waveform may be predictive of fluid responsiveness. The pleth variability index (PVI) was developed as a noninvasive bedside measurement of this variation in the pulse oxim...

BACKGROUND The pulse oximeter measurement pleth variability index (PVI) can detect hypovolaemia during positive pressure ventilation. OBJECTIVES We studied whether PVI can detect a hypovolaemic state in spontaneously breathing humans and whether better discrimination is obtained by modifying the breathing patterns. DESIGN Experimental study. SETTING Clinical physiology department in a uni...

INTRODUCTION Pulmonary vein isolation (PVI) is the state-of-the-art treatment of atrial fibrillation (AF). Pulmonary vein reconnection is one of the main mechanisms of AF recurrence after ablation. Catheter-tissue contact is essential for effective ablation lesions. The aim of this study was to evaluate the impact of catheter contact monitoring during PVI on AF recurrence rate. MATERIAL AND M...

BACKGROUND Catheter ablation is an established yet evolving nonpharmacologic intervention for the maintenance of sinus rhythm in patients with atrial fibrillation (AF). The efficacy and safety of pulmonary vein isolation (PVI) compared with medical therapy remain in question. METHODS AND RESULTS We conducted a meta-analysis of all randomized, controlled trials comparing PVI and medical therap...

BACKGROUND To compare the efficacy of three antiseptic solutions [0.5%, and 1.0% alcohol/chlorhexidine gluconate (CHG), and 10% aqueous povidone-iodine (PVI)] for the prevention of intravascular catheter colonization, we conducted a randomized controlled trial in patients from 16 intensive care units in Japan. METHODS Adult patients undergoing central venous or arterial catheter insertions we...
