STUDY OBJECTIVE: To compare the frequency of airway and respiratory adverse events leading to an intervention between moderate sedation using alfentanil or propofol. METHODS: We performed a randomized clinical trial in which adults undergoing moderate sedation in the ED received either alfentanil or propofol. Our primary outcome was the frequency of airway and respiratory adverse events leading to an intervention. Other outcomes included sedation depth, efficacy, sedation time, patient satisfaction, pain, and satisfaction...

Propofol is a general anesthetic commonly used in pediatric clinical practices. Experimental findings demonstrate that anesthetics induce widespread apoptosis and cognitive decline in a developing brain. Although anesthesia-mediated neurotoxicity is the most prominent during intense period of synaptogenesis, the effects of an early anesthesia exposure on the synapses are not well understood. The aim of this study was to examine the effects of neonatal propofol anesthesia on the expression of key proteins that participate in synaptogenesis and synaptic plasticity and to evaluate long-term neurobehavioral abnormalities in the mature adult brain...

BACKGROUND: The co-administration of ketamine and propofol (CoKP) is thought to maximize the beneficial profile of each medication, while minimizing the respective adverse effects of each medication. OBJECTIVE: Our objective was to compare adverse events between ketamine monotherapy (KM) and CoKP for procedural sedation and analgesia (PSA) in a pediatric emergency department (ED). METHODS: This was a prospective, randomized, single-blinded, controlled trial of KM vs...

Opsoclonus myoclonus syndrome (OMS) is a rare, neurological condition affecting 1 in 10 000 000 people annually. Opsoclonus, defined as involuntary rapid, multivectorial oscillations of the eyes, together with ataxia and myoclonus are usually present. OMS may be paraneoplastic: often associated with occult neuroblastoma in childhood and with breast carcinoma or small cell lung carcinoma in adults. Other aetiologies include viral or toxic agents. The pathogenesis is thought to be immune mediated. A 37-year-old woman with previous inflammatory cranial mononeuropathies was admitted for elective dilatation and curettage (D&C)...

BACKGROUND: In animal models, both sevoflurane and propofol protect against acute lung injury (ALI), especially when administered prior to ALI onset. We hypothesized that when compared to propofol, sevoflurane administration after the onset of acute respiratory distress syndrome would mitigate oleic acid (OA)-induced ALI in dogs. METHODS: Dogs were randomly assigned to receive intravenous OA to induce ALI (n = 7 for each OA group) or saline as an OA control (n = 6 for each control)...

A novel series of optically active 2,6-disubstituted alkylphenols with improved anesthetic profiles compared to widely used propofol were synthesized. The incorporation of the cyclopropyl group not only increased the steric effect but also introduced stereoselective effects over their anesthetic properties. Compounds 1, 2 and 6 were selected as potential candidates for further pre-clinical development including studies of their water-soluble prodrugs. Clinical studies of candidate compound 6 (Haisco HSK3486) as a general anesthetic are performed in Australia and China...

Tumor hypoxia has been recognized as a characteristic of the tumor microenvironment and promotes metastasis in a variety of types of cancer. However, in lung cancer, the role of hypoxia-inducible factor 1α (HIF-1α) in modulating the cellular response to the inflammation-related microenvironment remains unclear. In the present study, enhanced expression of HIF-1α accompanied by an increased ROS level was observed in lipopolysaccharide (LPS)-stimulated non-small cell lung cancer (NSCLC) cells. In addition, propofol, a general anesthetic, was found to significantly reduce the LPS-induced upregulation of HIF-1α and ROS in a dose-dependent manner...

INTRODUCTION: Little data exists regarding optimal therapeutic strategies post-operatively after lung transplant (LTx). Current practice patterns rely on expert opinion and institutional experience resulting in non-uniform post-operative care. To better define current practice patterns, an international survey of LTx clinicians was conducted. METHODS: A 30-question survey was sent to transplant clinicians via email to the ISHLT open forum mailing list and directly to the chief transplant surgeon and pulmonologist of all LTx centers in the United States...

INTRODUCTION: Awake craniotomy allows continuous monitoring of patients' neurological functions during open surgery. Anesthesiologists have to sedate patients in a way so that they are compliant throughout the whole surgical procedure, nevertheless maintaining adequate analgesia and anxiolysis. Currently, the use of α2-receptor agonist dexmedetomidine as the primary hypnotic-sedative medication is increasing. METHODS: Nine patients undergoing awake craniotomy were treated with refined monitored anesthesia care (MAC) protocol consisting of a combination of local anesthesia without scalp block, low-dose infusion of dexmedetomidine, propofol, and remifentanil, without the need of airways management...

What is the level of consciousness of the psychedelic state? Empirically, measures of neural signal diversity such as entropy and Lempel-Ziv (LZ) complexity score higher for wakeful rest than for states with lower conscious level like propofol-induced anesthesia. Here we compute these measures for spontaneous magnetoencephalographic (MEG) signals from humans during altered states of consciousness induced by three psychedelic substances: psilocybin, ketamine and LSD. For all three, we find reliably higher spontaneous signal diversity, even when controlling for spectral changes...

BACKGROUND: Postoperative agitation or confusion is one of the symptoms of hyperactive delirium in elderly patients. We retrospectively evaluated the incidence of postoperative abnormal psychomotor behaviour in elderly surgical patients according to the use of different intraoperative sedative agents: dexmedetomidine vs. propofol. METHODS: The medical records of 855 elderly patients, who underwent orthopaedic surgery with regional anaesthesia between July 2012 and September 2015, were divided into two groups-the dexmedetomidine group (n=263) and the propofol group (n=592)-and evaluated...

An 11-year-old male receiving aripiprazole, methylphenidate, and clonidine developed acute masseter dystonia inhibiting tracheal intubation after induction of general anesthesia with propofol and rocuronium. Following emergence, he had trismus and jaw discomfort. Psychiatry consultation suspected an acute dystonic reaction, so diphenhydramine was administered intravenously which resolved symptoms. We suspect chronic aripiprazole and methylphenidate usage combined with propofol administration in the short-term absence of methylphenidate made this patient susceptible to dystonic reactions...

Propofol and dexmedetomidine are both commonly used anaesthetics. Although they employ two different mechanisms to induce anaesthesia, both compounds influence the hippocampus and the HT22 cell line. HT22 cells are broadly used in neurobiological research. In this study, we assessed the effects of propofol and dexmedetomidine on signalling in HT22 cells. Using the SILAC (stable isotope labelling with amino acids in cell culture) labelling technique, IMAC (immobilized metal affinity chromatography) enrichment and high-resolution LC-MS/MS (liquid chromatography tandem mass spectrometry) analysis, we investigated the quantitative proteome and phosphoproteome in HT22 cells treated with propofol or dexmedetomidine...
