Managing opioid-induced constipation in advanced illness: focus on methylnaltrexone bromide.
Constipation is a common symptom in palliative care patients which can generate considerable suffering. There is uncertainty about the choice of treatment options from varying recommendations for management of constipation and a varying clinical practice in palliative care settings. The purpose of the review was to evaluate the current recommendations of therapy guidelines for the management of opioid-induced constipation in palliative care patients with a focus on methylnaltrexone bromide. ⋯ Diagnosis and therapy of constipation, therefore, should relate to findings in clinical investigation. Opioid-induced constipation and its adequate treatment is an important issue for patients with advanced illness and also poses therapeutic challenge for clinicians in daily routine. Methylnaltrexone bromide may represent an important therapeutic option for palliative care patients who are suffering from opioid-induced constipation with failure of conventional prophylactic oral laxative treatment.

Intravenous lipid emulsion for treatment of local anesthetic toxicity.
Is intravenous lipid emulsion a safe and effective therapy for the reversal and treatment of local anesthetic toxicity? ⋯ Intravenous lipid emulsion 20% should be available whenever patients receive large doses of local anesthetics in operating rooms and emergency departments. Various dosing protocols have been published in the medical literature. Although the dosing protocols are based on low-level evidence, a lack of major adverse events makes lipid emulsion an appropriate therapy for treating cardiotoxic symptoms induced by local anesthetics.

A review of the applications of the hydrofiber dressing with silver (Aquacel Ag) in wound care.
Aquacel Ag((R)) (ConvaTec, Princeton, NJ, USA) is a new hydrofiber wound dressing consisting of soft non-woven sodium carboxymethylcellulose fibers integrated with ionic silver. It is a moisture-retention dressing, which forms a gel on contact with wound fluid and has antimicrobial properties of ionic silver. We present a current literature review on Aquacel Ag((R)), of both in vitro and in vivo efficacy and clinical applications. ⋯ Clinical studies confirmed that Aquacel Ag((R)) is an effective and safe dressing for a variety of wound types, both acute and chronic. Incorporation of ionic silver into the hydrofibers does not cause undue alteration in the performance properties of the base dressing, which continues to provide favorable wound moisture and exudate management. The addition of ionic silver reduces local pain and dressing changes, and provides significant broad-spectrum antimicrobial properties, with no delay in wound healing.

Update on dexmedetomidine: use in nonintubated patients requiring sedation for surgical procedures.
Dexmedetomidine was introduced two decades ago as a sedative and supplement to sedation in the intensive care unit for patients whose trachea was intubated. However, since that time dexmedetomidine has been commonly used as a sedative and hypnotic for patients undergoing procedures without the need for tracheal intubation. This review focuses on the application of dexmedetomidine as a sedative and/or total anesthetic in patients undergoing procedures without the need for tracheal intubation. ⋯ Dexmedetomidine may by useful in patients needing sedation without tracheal intubation. The literature suggests potential use of dexmedetomidine solely or as an adjunctive agent to other sedation agents. Dexmedetomidine was especially useful when spontaneous breathing was essential such as in procedures on the airway, or when sudden awakening from sedation was required such as for cooperative clinical examination during craniotomies.
