Anesthesia awareness is defined as both consciousness and recall of surgical events. New research has been conducted out to test this phenomenon. ⋯ Moreover, patients who experience an intraoperative awareness can develop serious post-traumatic stress disorders that should not be overlooked. In this review, we introduce the incidence of intraoperative awareness during general anesthesia and discuss the mechanisms of consciousness, as well as risk factors, various monitoring methods, outcome and prevention of intraoperative awareness.

The simultaneous application of positive-end expiratory pressure with the Trendelenburg position minimizes respiratory fluctuations in internal jugular vein size.
The respiratory cycle alters the size of the right internal jugular vein (RIJV). We assessed the changes in RIJV size during the respiratory cycle in patients under positive pressure ventilation. Moreover, we examined the effects of positive-end expiratory pressure (PEEP) and the Trendelenburg position on respiratory fluctuations. ⋯ A 10° Trendelenburg tilt position combined with a PEEP of 10 cmH2O not only increases the size of the RIJV but also reduces fluctuation by the respiratory cycle.

The influence of different mechanical ventilator settings of peak inspiratory pressure on stroke volume variation in pediatric cardiac surgery patients.
The usefulness of dynamic parameters derived by heart-lung interaction for fluid responsiveness in pediatric patients has been revealed. However, the effects of peak inspiratory pressure (PIP) that could affect the absolute values and the accuracy in pediatric patients have not been well established. ⋯ SVV is affected by different levels of PIP in same patient and under same volume status. This finding must be taken into consideration when SVV is used to predict fluid responsiveness in mechanically ventilated pediatric patients.

Comparison of the efficacy of a forced-air warming system and circulating-water mattress on core temperature and post-anesthesia shivering in elderly patients undergoing total knee arthroplasty under spinal anesthesia.
In the present study, we compared changes in body temperature and the occurrence of shivering in elderly patients undergoing total knee arthroplasty under spinal anesthesia during warming with either a forced-air warming system or a circulating-water mattress. ⋯ The circulating-water mattress was as effective as the forced-air warming system for maintaining body temperature. However, the forced-air warming system was superior to the circulating-water mattress in reducing the incidence of post-anesthesia shivering.

Cardiopulmonary resuscitation with assisted extracorporeal life support during cardiac arrest caused by drug-eluting stent thrombosis: a case report.
Discontinuation of dual antiplatelet therapy within 12 months after drug-eluting stent (DES) implantation increases the possibility of stent thrombosis. We now report the case of a 66-year-old man who suffered a cardiac arrest due to stent thrombosis after an elective laparoscopic anterior resection. Ten month ago, he underwent DES implantation and then had been taking dual antiplatelet therapy. ⋯ Forty minutes after intensive care unit admission, cardiac arrest occurred. However, his cardiac rhythm did not restore in spite of resuscitation, so immediately veno-arterial extracorporeal membrane oxygenation (ECMO) was implanted. Four days after the surgery, he was weaned from ECMO support, recovered completely, with no cardiopulmonary or neurological sequelae.
