Therapeutics and clinical risk management
-
Sepsis and septic shock are important causes of mortality in intensive care unit patients, hence early diagnosis and therapy are important in management of their treatment. The available information on sepsis patients is not enough to recommend or to discard the routine evaluation of triglyceride (TG) levels at the onset of sepsis. The aim of this study was to investigate the association of hypertriglyceridemia and clinical outcome (or mortality) in patients with severe sepsis. ⋯ It was observed in this study that patients in the intensive care unit with sepsis had high TG levels. We also observed that the TG level >150 mg/dL at 0 hour (onset of sepsis) was a significant predictive marker of sepsis mortality rate. The contribution of hypertriglyceridemia to mortality might be modest compared to increase in severity of illness, but, nevertheless, these simple measurements represent a potential therapeutic target in sepsis.

Engineering practice variation through provider agreement: a cluster-randomized feasibility trial.
Minimal-risk randomized trials that can be embedded in practice could facilitate learning health-care systems. A cluster-randomized design was proposed to compare treatment strategies by assigning clusters (eg, providers) to "favor" a particular drug, with providers retaining autonomy for specific patients. Patient informed consent might be waived, broadening inclusion. However, it is not known if providers will adhere to the assignment or whether institutional review boards will waive consent. We evaluated the feasibility of this trial design. ⋯ Providers prescribed according to an assigned drug-choice strategy most of the time for the purpose of a comparative effectiveness study. This simple design could facilitate research participation and behavior change in non-research clinicians. Waiver of patient consent can broaden the representation of patients, providers, and settings.

The dexmedetomidine concentration required after remifentanil anesthesia is three-fold higher than that after fentanyl anesthesia or that for general sedation in the ICU.
The general dexmedetomidine (DEX) concentration required for sedation of intensive care unit patients is considered to be approximately 0.7 ng/mL. However, higher DEX concentrations are considered to be required for sedation and/or pain management after major surgery using remifentanil. We determined the DEX concentration required after major surgery by using a target-controlled infusion (TCI) system for DEX. ⋯ The DEX concentration required after AAA surgery with remifentanil was three-fold higher than that required after AAA surgery with fentanyl or the conventional DEX concentration for sedation. High DEX concentration after remifentanil affords some benefits in anesthetic management.
