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.

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 TrialFlurbiprofen Axetil Provides Effective Analgesia Without Changing the Pregnancy Rate in Ultrasound-Guided Transvaginal Oocyte Retrieval: A Double-Blind Randomized Controlled Trial.
In this prospective double-blind randomized study, we evaluated the analgesic effect and potential effect on pregnancy rate of the nonsteroidal anti-inflammatory drug flurbiprofen axetil in patients undergoing ultrasound-guided transvaginal oocyte retrieval under propofol-remifentanil anesthesia. ⋯ Flurbiprofen axetil given before ultrasound-guided transvaginal oocyte retrieval for patients under propofol-remifentanil general anesthesia relieves pain without any detrimental effect on clinical pregnancy rate.

Randomized Controlled Trial Pragmatic Clinical TrialXenon as an Adjuvant to Propofol Anesthesia in Patients Undergoing Off-Pump Coronary Artery Bypass Graft Surgery: A Pragmatic Randomized Controlled Clinical Trial.
Xenon was shown to cause less hemodynamic instability and reduce vasopressor needs during off-pump coronary artery bypass (OPCAB) surgery when compared with conventionally used anesthetics. As xenon exerts its organ protective properties even in subanesthetic concentrations, we hypothesized that in patients undergoing OPCAB surgery, 30% xenon added to general anesthesia with propofol results in superior hemodynamic stability when compared to anesthesia with propofol alone. ⋯ Thirty percent xenon added to propofol anesthesia improves hemodynamic stability by decreasing norepinephrine requirements in patients undergoing OPCAB surgery.
