Randomized Controlled TrialEffects of Esmolol on the Esophagogastric Junction: A Double-Blind, Randomized, Crossover Study on 14 Healthy Volunteers.
Passive regurgitation may occur throughout the perioperative period, increasing the risk for pulmonary aspiration and postoperative pulmonary complications. Hypnotics and opioids, especially remifentanil, that are used during anesthesia have been shown to decrease the pressure in the esophagogastric junction (EGJ), that otherwise acts as a barrier against passive regurgitation of gastric contents. Esmolol, usually used to counteract tachycardia and hypertension, has been shown to possess properties useful during general anesthesia. Like remifentanil, the β-1-adrenoreceptor antagonist may be used to attenuate the stress reaction to tracheal intubation and to modify perioperative anesthetic requirements. It may also reduce the need for opioids in the postoperative period. Its action on the EGJ is however unknown.The aim of this trial was to compare the effects of esmolol and remifentanil on EGJ pressures in healthy volunteers, when administrated as single drugs. ⋯ Esmolol, compared with remifentanil, does not affect EGJ function. This may be an advantage regarding passive regurgitation and esmolol may thus have a role to play in anesthesia where maintenance of EGJ barrier function is of outmost importance.

Meta AnalysisMethodological and Reporting Quality of Systematic Reviews Published in the Highest Ranking Journals in the Field of Pain.
Systematic reviews (SRs) are important for making clinical recommendations and guidelines. We analyzed methodological and reporting quality of pain-related SRs published in the top-ranking anesthesiology journals. ⋯ Endorsement of PRISMA in instructions for authors was not a guarantee of compliance. Methodological and reporting quality of pain-related SRs should be improved using relevant checklists. This can be remedied by a joint effort of authors, editors, and peer reviewers.

Persistent singultus, hiccupping that lasts for longer than 48 hours, can have a tremendous impact on a patient's quality of life. Although involved neurologic structures have been identified, the function of hiccups remains unclear-they have been controversially interpreted as a primitive reflex preventing extent swallowing of amniotic fluid in utero, an archaic gill ventilation pattern, or a fetus' preparation for independent breathing. Persistent singultus often presents as a symptom for various diseases, most commonly illnesses of the central nervous system or gastrointestinal tract; they can also be evoked by a variety of pharmacological agents. ⋯ As another approach of note, acupuncture treatment was able to abolish hiccups in a number of studies. When managing hiccup patients within the clinical routine, it is of importance to conduct a comprehensive and effective diagnostic workup; a well-functioning interdisciplinary team is needed to address possible causes for the symptom. Persistent singultus is a medical problem not to be underestimated; more research on options for effective treatment would be greatly needed.

Randomized Controlled TrialEffect of Endotracheal Tube Cuff Shape on Postoperative Sore Throat After Endotracheal Intubation.
Although minor, a sore throat after endotracheal intubation can adversely affect patient satisfaction and postoperative function. We compared the effects of 2 endotracheal tube cuff shapes on postoperative sore throat. ⋯ Intubation using an endotracheal tube with a tapered cuff reduced the incidence and severity of postoperative sore throat and the incidence of hoarseness after surgery when compared with an endotracheal tube with a cylindrical cuff.

Randomized Controlled TrialImpact of Simulator-Based Training in Focused Transesophageal Echocardiography: A Randomized Controlled Trial.
The aim of the study was to determine if training in transesophageal echocardiography (TEE) using a TEE simulator improves the ability of novice operators to perform and interpret a focused critical care TEE. ⋯ Simulation-based TEE training improves the ability of novice operators to perform a focused critical care TEE in comparison to lecture-based education only. After 8 hours of simulator and lecture-based training, the majority of TEEs of novices are of sufficient quality for clinical use. Furthermore, a substantial skill level in correct quantification and interpretation of imaging is achieved.
