Prognostic values of blood pH and lactate levels in patients resuscitated from out-of-hospital cardiac arrest.

Aim: Early prediction of prognosis after out-of-hospital cardiac arrest (OHCA) remains difficult. High blood lactate or low pH levels may be associated with poor prognosis in OHCA patients, but these associations remain controversial. We compared blood lactate and pH levels in OHCA patients transferred to our hospital to measure their prognostic performance.

Prevalence of metabolic syndrome in stroke patients: a prospective multicenter study in Japan.

Aims: The fact that Metabolic Syndrome (MetS) increases the risk of atherosclerosis has been epidemiologically studied and proven; however, a prospective study on the prevalence of MetS in stroke patients has never been conducted because of the difficulty in diagnosis under critical illness in the acute phase. Therefore, we conducted a prospective multicenter study to investigate the prevalence of MetS in stroke patients with modified diagnostic criteria for MetS.

Methods: Stroke patients admitted in the seven participating Emergency and Critical Care Centers within the two years from April 2007 were registered in this study as a prospective multicenter study.

Usefulness of serum concentration measurement for acute pentobarbital intoxication in patients.

Toxicokinetic parameters were analyzed in 25 patients who were acutely intoxicated with pentobarbital. The serum pentobarbital concentrations were at hypnotic / therapeutic levels (1- 10 microg/mL) in 11 patients, at toxic levels (10-24 microg/mL) in 10 patients, and at lethal levels (>24 microg/mL) in 4 patients. One fatal case was encountered with a serum pentobarbital concentration of 37.

[Serum fenitrothion concentration and toxic symptom in acute intoxication patients].

The serum drug concentrations were measured by HPLC or GC/MS in 15 patients of acute fenitrothion (MEP), an organophosphorus insecticide, intoxication. There was no fatal case. The patients were admitted 0.

[Pharmacokinetics of bromazepam in 57 patients with acute drug intoxication].

Pharmacokinetic parameters of bromazepam were analyzed by 57 cases. The patients were admitted 7.3 +/- 8.
