Randomized Controlled Trial Comparative Study Clinical TrialIs the ARX index a more sensitive indicator of anesthetic depth than the bispectral index during sevoflurane/nitrous oxide anesthesia?
During general anesthesia, hypnotic components have been monitored with electroencephalogram. The bispectral index is derived from a cortical electroencephalogram, but the A-line ARX index is the electroencephalographic response to auditory stimuli. The purpose of this study was to compare the changes of the A-line ARX index and the bispectral index during sevoflurane - nitrous oxide anesthesia. ⋯ During sevoflurane-nitrous oxide anesthesia, the A-line ARX index might be a more sensitive indicator of anesthetic depth than the bispectral index.

Comparative StudyInfluence of formulation on propofol pharmacokinetics and pharmacodynamics in anesthetized patients.
In anesthesia with propofol, variability persists besides sophisticated effect targeting. Drug formulation may be another factor. We have analyzed, retrospectively, the pharmacokinetics (PK) and pharmacodynamics (PD) in monitored surgery patients anesthetized with one each of five formulations of propofol. ⋯ The PK and PD are not equal for all formulations, which contributes to an increase in variability of the observed effect.

Comparative StudyComparative analysis of in vitro contracture tests with ryanodine and a combination of ryanodine with either halothane or caffeine: a comparative investigation in malignant hyperthermia.
The diagnosis of susceptibility to malignant hyperthermia (MH) is currently performed on muscle biopsies subjected to halothane-caffeine in vitro contracture tests (IVCTs). There is a consensus on our need to improve the diagnostic potential of IVCTs if we are to maximize the information available for research and diagnosis in MH. This study was designed as a pilot comparative study and we aimed at comparing the ryanodine test and new tests using a combination of ryanodine, halothane and caffeine. ⋯ This pilot study showed a clear diagnostic potential for new IVC tests combining halothane, the triggering agent of MH, and ryanodine acting at the calcium release channel, and should be considered as a first step in the investigation of combined tests.

Clinical TrialAcute acalculous cholecystitis in critically ill patients.
Acute acalculous cholecystitis (AAC) is a serious complication of critical illness. We evaluated the underlying diseases, clinical and diagnostic features, severity of associated organ failures, and outcome of operatively treated AAC in a mixed ICU patient population. ⋯ Acute acalculous cholecystitis was associated with severe illness, infection, long ICU stay, and multiple organ failure. Mortality was related to the degree of organ failure. Prompt diagnosis and active treatment of AAC can be life-saving in these patients.

Primary sepsis in a university hospital in northern Sweden: a retrospective study.
Severe sepsis and septic shock are associated with high mortality rates. Data on sepsis outcome from Scandinavian countries are sparse. The aim of this study was to examine the length of stay (LOS) in the ICU, ICU mortality and costs of care for adult patients with primary sepsis in a university hospital in northern Sweden. ⋯ The incidence of primary sepsis in our ICU was low. Previous reports on high mortality in association with severe sepsis and septic shock are valid also at our hospital. The ICU-LOS was shorter than previously reported, while our costs of care were in the same range as stated by others. This retrospective analysis is valid for interpretation of the applicability of currently available sepsis therapies.
