Dexmedetomidine, is a selective α2-adrenoceptor agonist that is used as an adjuvant mixed with local anesthetics during regional anesthesia. This study was designed to test the efficacy of adding dexmedetomidine to bupivacaine during placement of infraclavicular brachial plexus blockade (ICB). ⋯ ADDING DEXMEDETOMIDINE TO BUPIVACAINE DURING THE PLACEMENT OF AN ICB PROVIDES: (1) enhancement of onset of sensory and motor blockade, (2) prolonged duration of analgesia, (3) increases duration of sensory and motor block, (4) yields lower VRS pain scores, and (5) reduces supplemental opioid requirements.

The efficacy of using midazolam or haloperidol for prevention of postoperative nausea and vomiting (PONV) has been investigated before. The main object of the present study was to evaluate the anti-emetic effects of combining administration of intravenous haloperidol with intravenous midazolam on PONV in patients underwent middle ear surgery in comparison with using each drug alone. ⋯ Combine administration of haloperidol 2 mg plus midazolam 2 mg significantly reduced PONV better than using each drug alone in patients underwent middle ear surgery under general anesthesia.

Institutions and journals both have important duties relating to research and publication misconduct. Institutions are responsible for the conduct of their researchers and for encouraging a healthy research environment. Journals are responsible for the conduct of their editors, for safeguarding the research record, and for ensuring the reliability of everything they publish. ⋯ To achieve this, we make the following recommendations. The institutions should:have a research integrity officer (or office) and publish their contact details prominentlyinform journals about cases of proven misconduct that affect the reliability or attribution of the research that they have publishedrespond to journals if they request information about issues, such as, disputed authorship, misleading reporting, competing interests, or other factors, including honest errors, that could affect the reliability of the published studyinitiate inquiries into allegations of research misconduct or unacceptable publication practice raised by journalshave policies supporting a responsible research conduct and systems in place for investigating suspected research misconduct. The journals should:publish the contact details of their editor-in-chief who should act as the point of contact for questions relating to research and publication integrityinform institutions if they suspect misconduct by their researchers, and provide evidence to support these concernscooperate with investigations and respond to institutions' questions about misconduct allegationsbe prepared to issue retractions or corrections (according to the COPE guidelines on retractions) when provided with findings of misconduct arising from investigationshave policies for responding to institutions and other organizations that investigate cases of research misconduct.

Percutaneous central venous cannulation (CVC) in infants and children is a challenging procedure, and it is usually achieved with a blinded, external landmark-guided technique. Recent guidelines from the National Institute for Clinical Excellence (NICE) recommend the use of ultrasound guidance for central venous catheterization in children. The purpose of this study was to evaluate this method in a pediatric and neonatal intensive care unit, assessing the number of attempts, access time (skin to vein), incidence of complication, and the ease of use for central venous access in the neonatal age group. ⋯ In a sample of critically ill patients from a pediatric and neonatal intensive care unit, ultrasound-guided CVC compared with published reports on traditional technique required fewer attempts and less time. It improved the overall success rate, minimized the occurrence of complications during vein cannulation and was easy to apply in neonatal and pediatric patients.

The aim of this double-blind, prospective, randomized, controlled study was to compare the effect of addition of ketamine; fentanyl and saline with propofol anesthesia on hemodynamic profile and laryngeal mask airway (LMA) insertion conditions in oral clonidine premedicated children. ⋯ Even in oral clonidine premedicated children, addition of ketamine with propofol provides hemodynamic stability and comparable conditions for LMA insertion like fentanyl propofol with significantly less prolonged apnea.
