Randomized Controlled Trial Multicenter Study Observational Study
Association between intraoperative electroencephalographic suppression and postoperative mortality.
Low bispectral index values frequently reflect EEG suppression and have been associated with postoperative mortality. This study investigated whether intraoperative EEG suppression was an independent predictor of 90 day postoperative mortality and explored risk factors for EEG suppression. ⋯ NCT00281489 and NCT00682825.

Our previous reports demonstrated that genetic deletion of μ-opioid receptor has no influence on the anaesthetic and antinociceptive effects of nitrous oxide (N2O) in mice, and that an antagonist selective for κ-opioid receptor (KOP), but not that selective for δ-opioid receptor, suppresses the antinociceptive effect of N2O. However, it is not known whether genetic deletion of KOP affects the N2O actions. ⋯ Our study suggests that N2O demonstrates its antinociceptive action and reduces sevoflurane MAC in mice through KOP activation, whereas its hypnotic potency is not dependent on KOP activation.

The number of people travelling to malaria-endemic countries continues to increase, and malaria remains the commonest cause of serious imported infection in non-endemic areas. Severe malaria, mostly caused by Plasmodium falciparum, often requires intensive care unit (ICU) admission and can be complicated by cerebral malaria, respiratory distress, acute kidney injury, bleeding complications, and co-infection. ⋯ Effective management of severe malaria includes prompt diagnosis and early institution of effective anti-malarial therapy, recognition of complications, and appropriate supportive management in an ICU. All cases should be discussed with a specialist unit and transfer of the patient considered.
