There is a need for alternative non-opioid analgesics for the treatment of acute, chronic, and refractory pain in the emergency department (ED). Ketamine is a fast acting N-methyl-d-aspartate (NMDA) receptor antagonist that provides safe and effective analgesia. The use of low dose ketamine (LDK) (<1mg/kg) provides sub-dissociative levels of analgesia and has been studied as an alternative and/or adjunct to opioid analgesics. We reviewed 11 studies using LDK either alone or in combination with opioid analgesics in the ED...

OBJECTIVE: Emergency physicians often need to control agitated patients who present a danger to themselves and hospital personnel. Commonly used medications have limitations. Our primary objective was to compare the time to a defined reduction in agitation scores for ketamine versus benzodiazepines and haloperidol, alone or in combination. Our secondary objectives were to compare rates of medication redosing, vital sign changes, and adverse events in the different treatment groups. METHODS: We conducted a single-center, prospective, observational study examining agitation levels in acutely agitated emergency department patients between the ages of 18 and 65 who required sedation medication for acute agitation...

BACKGROUND: Local anesthetics are commonly used in the emergency department (ED). Overdoses can lead to disastrous complications including cardiac toxicity and arrest. Recognition of local anesthetic systemic toxicity (LAST) is important; however, prevention is even more critical. Knowledge of proper lidocaine dosage can prevent LAST. LAST may be effectively treated with lipid emulsion therapy. Although the mechanism is not well understood, its use may have a profound impact on morbidity and mortality...

REVIEW
Ghada M N Bashandy
The endothelial glycocalyx is a labile, fine structure coating the luminal membrane of intact healthy vascular endothelium. For many decades, no physiologic importance was linked to this structure. It is crucial for vascular barrier function. There has been an immense interest in recent years for studying this important structure, and research is needed to disclose more information about it. Perioperative damage of the glycocalyx has been demonstrated, and is linked with morbidity and even mortality in surgical patients...

REVIEW
Ashish Udeshi, Shawn Michael Cantie, Edgar Pierre
Postobstructive pulmonary edema (POPE; also known as negative pressure pulmonary edema) is a potentially life-threatening complication in which pulmonary edema occurs shortly after the relief of an upper airway obstruction. The incidence of POPE has been reported to be as high as 1 in 1000 general anesthetic cases and commonly presents as acute respiratory distress that requires immediate intervention. This review examines the 2 subclasses of POPE and describes the etiologic factors, pathophysiology, clinical manifestations, diagnostic criteria, and treatment strategies associated with each...

Lei Yang, Hui Liu, Hai-Ying Sun, Gui-Rong Li
BACKGROUND: Propofol is widely used clinically for the induction and maintenance of anesthesia. Clinical case reports have shown that propofol has an antiatrial tachycardia/fibrillation effect; however, the related ionic mechanisms are not fully understood. The current study investigates the effects of propofol on human cardiac potassium channels. METHODS: The whole cell patch voltage clamp technique was used to record transient outward potassium current (Ito) and ultrarapidly activating delayed rectifier potassium current (IKur) in human atrial myocytes and hKv1...

The paper examines the effects of anaesthesia on circulatory physiology and their implications regarding improvement in perioperative anaesthetic management. Changes to current anaesthetic practice, recommended recently, such as the use of flow monitoring in high risk patients, are already beginning to have an impact in reducing complications but not mortality [1]. Better understanding of the patho-physiology should help improve management even further. Analysis of selected individual clinical trials has been used to illustrate particular areas of patho-physiology and how changes in practice have improved outcome...

REVIEW
Thomas Schricker, Ralph Lattermann
PURPOSE: This article reviews the pathophysiology, clinical relevance, and therapy of the catabolic response to surgical stress. PRINCIPLE FINDINGS: The key clinical features of perioperative catabolism are hyperglycemia and loss of body protein, both metabolic consequences of impaired insulin function. Muscle weakness and (even moderate) increases in perioperative blood glucose are associated with morbidity after major surgery. Although the optimal glucose concentration for improving clinical outcomes is unknown, most medical associations recommend treatment of random blood glucose > 10 mmol·L(-1)...

Intravenous lipid emulsion (ILE) is a lifesaving treatment of lipophilic drug intoxications. Not only does ILE have demonstrable efficacy as an antidote to local anesthetic toxicity, it is also effective in lipophilic drug intoxications. Our case series involved 10 patients with ingestion of different types of lipophilic drugs. Intravenous lipid emulsion treatment improved Glasgow Coma Scale or blood pressure and pulse rate or both according to the drug type. Complications were observed in 2 patients (minimal change pancreatitis and probable ILE treatment-related fat infiltration in lungs)...

#14
REVIEW
Robert H Thiele, Marcel E Durieux
Qualitative arterial waveform analysis has been in existence for millennia; quantitative arterial waveform analysis techniques, which can be traced back to Euler's work in the 18th century, have not been widely used by anesthesiologists and other clinicians. This is likely attributable, in part, to the widespread use of the sphygmomanometer, which allows the practitioner to assess arterial blood pressure without having to develop a sense for the higher-order characteristics of the arterial waveform. The 20-year delay in the development of devices that measure these traits is a testament to the primitiveness of our appreciation for this information...

REVIEW

Dynamics of neuronal networks can be altered in at least two ways: by changes in connectivity, that is, the physical architecture of the network, or changes in the amplitudes and kinetics of the intrinsic and synaptic currents within and between the elements making up a network. We argue that the latter changes are often overlooked as sources of alterations in network behavior when there are also structural (connectivity) abnormalities present; indeed, they may even give rise to the structural changes observed in these states...

We investigated the effect of propofol and fentanyl on microelectrode recording (MER) and its clinical applicability during subthalamic nucleus (STN) deep brain stimulation (DBS) surgery. We analyzed 8 patients with Parkinson's disease, underwent bilateral STN DBS with MER. Their left sides were done under awake and then their right sides were done with a continuous infusion of propofol and fentanyl under local anesthesia. The electrode position was evaluated by preoperative MRI and postoperative CT. The clinical outcomes were assessed at six months after surgery...
