Prediction of bleeding and thrombosis by standard biochemical coagulation variables in haematological intensive care patients.
We assessed the value of standard biochemical coagulation parameters in predicting bleeding, thrombosis and mortality in adult Intensive Care Unit (ICU) patients with haematological malignancies. ⋯ Increased INR at admission was associated with a higher rate of bleeding in ICU patients with haematological malignancies. No other biochemical coagulation or other parameter had any association with bleeding, thrombosis or mortality except increased LDH, which at ICU admission was associated with increased 30-day mortality.

Observational StudyAttitudes of physicians towards the care of critically ill elderly patients - a European survey.
Very elderly patients are one of the fastest growing population in ICUs worldwide. There are lots of controversies regarding admission, discharge of critically ill elderly patients, and also on treatment intensity during the ICU stay. As a consequence, practices vary considerably from one ICU to another. In that perspective, we collected opinions of experienced ICU physicians across Europe on statements focusing on patients older than 80. ⋯ There are major differences in the attitude of European ICU physicians on the admission, triage and treatment policies of patients older than 80 emphasizing the lack of consensus and poor level of evidence for most of the statements and outlining the need for future interventional studies.

Lactate concentration is known to be a strong predictor of mortality, but is not included in any of the major intensive care scorings systems such as the Simplified Acute Physiology Score (SAPS 3). The objective of this study was to investigate the prognostic value of lactate concentration when combined with SAPS 3. ⋯ Even compared to our current prognostication model, SAPS 3, lactate concentration was found to be an independent predictor for all diagnoses, cardiac arrest and sepsis. The addition of lactate concentration level improved the AUC for cardiac arrest and sepsis, but not for all diagnoses.

Observational StudyHigh volatile anaesthetic conservation with a digital in-line vaporizer and a reflector.
A volatile anaesthetic (VA) reflector can reduce VA consumption (VAC) at the cost of fine control of its delivery and CO2 accumulation. A digital in-line vaporizer and a second CO2 absorber circumvent both of these limitations. We hypothesized that the combination of a VA reflector with an in-line vaporizer would yield substantial VA conservation, independent of fresh gas flow (FGF) in a circle circuit, and provide fine control of inspired VA concentrations. ⋯ A secondary circuit with reflector and in-line vaporizer provides highly efficient anaesthetic delivery, independent of FGF. A second CO2 absorber was necessary to scavenge the CO2 reflected by the anaesthetic reflector. This secondary circuit may turn any open circuit ventilator into an anaesthetic delivery unit.

Spinal or general anaesthesia for lower-limb amputation in peripheral artery disease - a retrospective cohort study.
The present study aimed to determine which method of anaesthesia (spinal anaesthesia or general anaesthesia) is better in reducing post-operative analgesic requirements in patients undergoing major limb amputation for lower-limb ischaemia. Another aim was to find out if anaesthesiologists use neuraxial anaesthesia in high-risk patients despite abnormal coagulation profile or use of anticoagulation. ⋯ Patients with spinal anaesthesia had a lower rate of surgical complications, re-operations and intensive care unit admissions. Patients with above-the-knee amputation and spinal anaesthesia had a lesser need for opioid medication in the post-operative period than patients with general anaesthesia. Anaesthesiologists performed neuraxial anaesthesia and/or analgesia in high-risk patients despite abnormal coagulation profile or ongoing anticoagulation, but no adverse outcomes were reported.
