Review Meta AnalysisBeta-adrenergic antagonists during general anesthesia reduced postoperative pain: a systematic review and a meta-analysis of randomized controlled trials.
We have performed a systematic literature review and a meta-analysis investigating the effect of beta-adrenergic antagonist on perioperative pain in randomized clinical trials (RCTs). The search included the CENTRAL, CINAHL, EMBASE, and MEDLINE databases (from inception to 10 February 2015). From the retrieved full texts, we hand-searched the references and PubMed related citations. ⋯ However, in two opioid-controlled studies, one in knee arthroscopy and another in tubal ligation patients, the proportion of patients needing rescue analgesia was two-times higher in esmolol-treated patients: 52-57 vs. 23-34%, p < 0.05. Adverse effects were rarely reported, and as reported were mostly cardiovascular alterations. In conclusion, intra-operative beta-adrenergic antagonists' administration may decrease postoperative pain and analgesic consumption when given as an adjuvant to general anesthesia.

Randomized Controlled Trial Comparative StudyThe effects of intravenous fosaprepitant and ondansetron in the prevention of postoperative nausea and vomiting in patients who underwent lower limb surgery: a prospective, randomized, double-blind study.
Postoperative nausea and vomiting (PONV) is the most common complication after surgery, and opioid administration increases its incidence. We compared the preventive effects of fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, with those of ondansetron on PONV in patients who underwent lower limb surgery with postoperative epidural opioid administration. ⋯ Fosaprepitant was more effective than ondansetron in decreasing the incidence of vomiting after lower limb surgery with postoperative opioid administration. Meanwhile, fosaprepitant was not inferior to ondansetron in decreasing the incidence and severity of PONV.

ReviewFactors affecting survival in pediatric cardiac tamponade caused by central venous catheters.
Pediatric central venous catheter (CVC) placement is useful but associated with complications such as cardiac tamponade. We aimed to identify risk factors for death in cardiac tamponade. Published articles on pediatric CVC-associated cardiac tamponade were obtained by searching PubMed and Google and retrospectively reviewed to analyze risk factors for death. ⋯ Multiple regression analysis in 44 cases showed that treatment (p < 0.0001) and initial CVC tip position (p = 0.020) were independent predictive factors related to improved cardiac tamponade survival. Past studies have mainly discussed how to avoid pediatric cardiac tamponade; by contrast, the present study focused on how to avoid deaths. The findings of this review suggest that cardiac tamponade survival is better when tamponade is detected early and treated promptly and might be affected by initial CVC tip position.

Comparative StudyEffect of intraoperative transesophageal Doppler-guided fluid therapy versus central venous pressure-guided fluid therapy on renal allograft outcome in patients undergoing living donor renal transplant surgery: a comparative study.
Transesophageal Doppler (TED)-guided intraoperative fluid therapy has shown to noninvasively optimize intravascular volume and reduce postoperative morbidity. The aim of this study was to compare the effects of Doppler-guided intraoperative fluid administration and central venous pressure (CVP)-guided fluid therapy on renal allograft outcome and postoperative complications. ⋯ FTc-guided intraoperative fluid therapy achieved the same rate of immediate graft function as CVP-guided fluid therapy but used a significantly less amount of fluid. The incidence of postoperative complications related to fluid overload was also reduced. The use of TED may replace invasive central line insertions in the future.

Comparative StudyAnalysis of factors related to vagally mediated reflex bradycardia during gastrectomy.
Because vagally mediated reflex bradycardia occurs frequently during gastrectomy and is potentially harmful, we compared the incidence of clinically significant reflex bradycardia between patients undergoing laparoscopic gastrectomy (LG) and open gastrectomy (OG) and examined whether the type of surgery (OG vs. LG) was an independent risk factor for clinically significant reflex bradycardia. ⋯ The LG approach was associated with a reduced risk of clinically significant reflex bradycardia compared with the OG approach.
