Dezocine attenuates fentanyl-induced cough in a dose-dependent manner-a randomized controlled trial.
Fentanyl-induced cough (FIC) should be effectively prevented in patients requiring stable induction of general anesthesia. Our study was to evaluate the suppressive effects of different doses of intravenous dezocine on FIC during the induction of general anesthesia. A total of 400 patients of American Society of Anesthesiologists (ASA) physical status I and II were randomized into four groups (n = 100). ⋯ Group IV had lower incidence of FIC than Groups II (0% vs 12%; P = 0.0003) and III (0% vs 4%; P = 0.043). Our study showed that intravenous dezocine reduced the incidence of FIC during anesthetic induction. The suppressive effect was dose-dependent.

This study is to investigate the predictive factors of blood loss in ankylosing spondylitis (AS) patients. Retrospective analysis was performed in patients with thoracolumbar kyphotic deformity secondary to ankylosing spondylitis who underwent PSO from 2008 through 2013. Patient's demographics, preoperative and postsurgical global kyphosis (GK) angle, preoperative hematologic tests and other factors related to PSO were analyzed. ⋯ Multiple stepwise analysis identified male sex (P = 0.000), and two-level osteotomy (P = 0.016) to be predictive factors of increased EBL/EBV percentage in AS patients undergoing PSO for thoracolumbar kyphosis. Male and two-level osteotomy are the two most significant factors predicting increased EBL/EBV percentage in AS patients undergoing PSO for thoracolumbar kyphosis. These predictors can provide more adequate preoperative preparations.

Postoperative nausea and vomiting (PONV) is a frequent complication in postoperative period. The aim of the current meta-analysis was to assess the efficacy of dexmedetomidine on PONV. ⋯ The present meta-analysis indicates that dexmedetomidine shows superiority to placebo, but not to all other anesthetic agents on PONV. And this efficacy may be related to a reduced consumption of intraoperative opioids.

Impulse oscillometry (IOS) is a good method for measuring airway resistance. The aim of this study was to assess the diagnostic contribution of IOS combined with bronchial dilation test (BDT) when distinguishing between patients with asthma and those with chronic obstructive pulmonary disease (COPD). 870 were enrolled in the study including 561 patients with asthma, 100 patients with COPD and 209 patients with chronic coughing or normal subjects. All the participants underwent routine pulmonary function tests, IOS and BDT examination. ⋯ Our findings show, that X5, X25 and Fres may be useful for predictions and evaluations for COPD. And R5, X35 and Zrs may provide useful IOS parameters for asthma. IOS combined BDT could be useful diagnostic and differential diagnosis between asthma and COPD.

Balloon kyphoplasty has been shown to be safe in treatment of vertebral compression fractures refractory to conservative management. However, few reports have focused on lateral wedging of cemented vertebra after kyphoplasty. A 72-year-old woman with a T12 osteoporotic compression fracture underwent kyphoplasty using polymethylmethacrylate (PMMA) via a bipedicular approach. ⋯ Twelve months later, lateral wedging of the cemented vertebra was detected in plain radiographs. In the kyphoplasty procedure, symmetric cement filling should be achieved to avoid lateral wedging of the cemented vertebra. Postoperative anti-osteoporotic medication treatment is also very important.
