Impact of anaesthesia-surgery on D-dimer concentration and end-tidal CO2 and O2 in patients undergoing surgery associated with high risk for pulmonary embolism.
The exhaled end-tidal CO2/O2 ratio and the D-dimer concentration are diagnostic markers of pulmonary embolism (PE). ⋯ The stress impact of anaesthesia-surgery causes less change in end-tidal CO2/O2 compared with the D-dimer. Further work will be required to determine if end-tidal CO2/O2 can be used to monitor for postoperative PE.

Transoesophageal echocardiography should be considered in patients with ischaemic stroke or transient ischaemic attack.
In this present study, we tried to find out if there is a subgroup of patients that should not undergo transoesophageal echocardiography (TEE) after an ischaemic stroke or transient ischaemic attack (TIA). ⋯ These results support TEE in patients with ischaemic stroke or TIA who are candidates for receiving oral anticoagulation.
