Case ReportsDecrease in bispectral index prior to cardiovascular collapse during Caesarean sections.
We report a case of significant reduction in bispectral index (BIS) associated with suspected amniotic fluid embolism (AFE) that occurred prior to change in haemodynamic variables. The patient was a 29-year-old nulliparous, who was admitted for Caesarean section under general anaesthesia in the 33rd week of pregnancy. ⋯ After administration of vasoactive drugs, the systolic BP was maintained at 100 mmHg or higher, the BIS value rose to 10-20, and the EtCO2 increased to 24-33 mmHg. In this case, the BIS monitoring may provide an earlier warning of impending cardiovascular collapse in the case of AFE.

Hyperglycaemia increases S100β after short experimental cardiac arrest.
Hyperglycaemia is associated with aggravated ischaemic brain injury. The main objective of this study was to investigate the effects on cerebral perfusion of 5 min of cardiac arrest during hyperglycaemia and normoglycaemia. ⋯ The enhanced S100β response is compatible with increased cerebral injury by hyperglycaemic compared with normoglycaemic 5 min of cardiac arrest and resuscitation. The inflammatory cytokines were similar between groups.
