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.

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.

Brachial plexus perineural blocks provide specific analgesia for upper limb surgery. We present our experience with ultrasound-guided supraclavicular brachial plexus perineural blocks for distal upper limb surgery. Although single-injection ultrasound-guided supraclavicular blocks have been reported, little is known about the advantages using this approach compared with nerve stimulator guided. ⋯ Supraclavicular brachial plexus perineural insertion using ultrasound guidance is feasible and almost have no complications, deserves further study with a randomized controlled trial comparing this relatively new technique with only using nerve stimulator.

Adolescent idiopathic scoliosis (AIS) is a structural 3-dimensional deformity the spine, which is occurring between 10 years of age and skeletal maturity and it mostly affects prepuberbal girls. The etiology of AIS remains unknown and seems should be multifactorial. According to the theories, there could be a shorter spinal cord or a higher location of the conus medullaris and disproportionate growth in neuro-osseous system. ⋯ The mean age of patients were 16.34 with 6.77 of conus medullaris position in mean, which was lower one-third of L1. Our study showed no significant correlation between the position of conus medullaris with age, weight, preoperative curve, flexibility, types of deformity based on Lenke classification and degree of kyphosis and lordisis. In conclusion, there is the same mean and the distribution of the conus medullaris locations for AIS patients and normal populations.

To estimate the efficacy and safety of adding bevacizumab to cetuximab- or panitumumab-based therapy in the treatment of patients with metastatic colorectal cancer (mCRC), using a meta-analysis of randomized controlled trials. ⋯ The addition of bevacizumab to cetuximab- or panitumumab-based therapy did not improve PFS and OS resulting in better ORR. Thus, the combined therapy of bevacizumab with cetuximab or panitumumab is not recommended for the treatment of mCRC. However, larger scale RCTs are needed to confirm these findings.
