Diabetes mellitus has diverse effects on all organ systems of the body. Insulin physiology and metabolic control are far more complex than previously thought. Research continues to reveal more information about the central role of insulin in metabolism. The treatment of hypertension and nephropathy as well as hyperglycemia in patients with diabetes has emerged as being critical for prevention of long-term diabetic complications. The issue of primary importance to the anesthesiologist is whether strict glycemic and hemodynamic control during the perioperative period affect outcome. ⋯ Tight long-term control of glucose and blood pressure improve outcome in patients with diabetes. The same philosophy of management is being applied to the perioperative period. Routine measurement of intraoperative blood glucose levels and appropriate insulin administration are now standard practice, but the ideal regimen for insulin administration remains to be determined.

Complex Regional Pain Syndrome Type-I (CRPS-I) is a neuropathic pain syndrome resulting from complex pain mechanisms that involve several levels and components of the nervous system. CRPS-I consists of multiple signs, including autonomic dysfunction, in the form of edema, vasomotor changes, motor dysfunctions, muscle spasms, tremors and dystonia, as well as burning pain, hypersensitivity and allodynia that could present in any combination. ⋯ Multiple analgesic modalities have been used to facilitate the rehabilitation program with varying rates of success. The most successful treatment is a multi-disciplinary comprehensive approach, where initial pain control allows for physical and psychological interventions that are believed to be the basis for successful treatment.(1) The pain in CRPS-I may be mediated through the sympathetic nervous system, sympathetic maintained pain (SMP) or sympathetic independent pain (SIP)(2).

Epidural clonidine has been proven effective in relieving intractable cancer pain, especially neuropathic. This phase I/II study was performed to investigate if intrathecal clonidine is well tolerated and effective for long-term treatment of intractable chronic pain. ⋯ This study demonstrates the tolerability and effectiveness of intrathecal clonidine in the treatment of chronic pain. The physician using clonidine for long-term intrathecal infusion should be cognizant of the risk that severe rebound systemic hypertension can occur with abrupt cessation of the intrathecal infusion of clonidine.

The management of ethylene glycol poisoning is reviewed, with a focus on the use of the new antidote fomepizole. Ethylene glycol is a widely used industrial agent that is also easily obtained commercially, usually as radiator antifreeze. Ingestion of as little as 30 to 60 mL can result in death or serious permanent disability. ⋯ Potential benefits of fomepizole include its ease of administration and lack of serious adverse effects. Fomepizole may be recommended over ethanol in situations in which avoidance of ethanol-induced side effects is imperative or when ethanol is not readily available. Further studies are required to verify its comparative efficacy and cost-effectiveness compared to ethanol.
