Clinical TrialPain-relieving effects of intravenous ATP in chronic intractable orofacial pain: an open-label study.
Chronic orofacial pain is often refractory to conventional pain therapies. We conducted an open-label study to determine whether adenosine 5'-triphosphate (ATP) could alleviate chronic intractable orofacial pain, and if so, which type of pain could respond to ATP. ⋯ Intravenous ATP did not relieve non-neuropathic orofacial pain. However, it exerted slowly expressed but long-lasting analgesic and anti-allodynic effects in patients with neuropathic orofacial pain, especially in those suffering from neuropathic pain following pulpectomy and/or tooth extraction.

Effects of nicardipine-induced hypotension on cerebrovascular carbon dioxide reactivity in patients with diabetes mellitus under sevoflurane anesthesia.
The purpose of this study was to examine the effects of nicardipine-induced hypotension on cerebrovascular CO2 reactivity in patients with diabetes mellitus under sevoflurane anesthesia. ⋯ We concluded that cerebrovascular CO2 reactivity in insulin-dependent patients is impaired during nicardipine-induced hypotension under sevoflurane anesthesia.

Case ReportsProlonged cardiac arrest unveiled silent sick sinus syndrome during general and epidural anesthesia.
Patients who have silent sick sinus syndrome (SSS) can show various unexpected arrhythmias during surgery. The severity of these bradyarrythmias is affected by anesthetic methods. We report a unique case of a patient with silent SSS who developed 40 s of asystole under combined general and epidural anesthesia. ⋯ During surgery, severe bradycardia, triggered by peritoneal manipulation, occurred, leading to 40 s of asystole. She was diagnosed as having SSS by a postoperative 24-h Holter electrocardiogram. We propose that the possible existence of SSS should be kept in mind even in a patient who shows no abnormalities on routine preoperative examination, especially in those in whom vagomimetic anesthetic methods are used.

Comparative StudyPrognostic value of serum myoglobin in patients after cardiac surgery.
Serum myoglobin as a marker of myocardial damage and injury has been shown to be of prognostic value in patients with cardiovascular events. In this study, we analyzed the prognostic value of serum myoglobin in comparison to other parameters of muscle damage and renal function in patients after cardiac surgery. ⋯ Serum myoglobin is associated with outcome in patients after cardiac surgery. Prediction of ICU mortality and need for RRT was comparable for myoglobin and creatinine, while both were significantly superior to CK.

Case ReportsAnesthetic management of a patient with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) during laparotomy.
A 53-year-old man with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) underwent a gastrectomy. We administered bicarbonated Ringer's solution, which has a physiological concentration of bicarbonate. ⋯ Aggressive warming was needed to maintain normothermia, presumably because the mitochondrial respiratory chain, which is responsible for thermogenesis, is impaired in MELAS patients. It is important to maintain normothermia in MELAS patients in order to avoid further mitochondrial metabolic depression.
