Meta Analysis Comparative StudyRegional or general anesthesia for carotid endarterectomy? Evidence from published prospective and retrospective studies.
The aim of this study was to compare outcomes of patients undergoing carotid endarterectomy under regional or general anesthesia for any new neurologic impairment, stroke, stroke and/or death, death, and myocardial infarction. ⋯ The number of patients included in randomized controlled trials or even in prospective studies is too low to allow any conclusions on the differences in outcome between the 2 anesthetic techniques. Better outcomes are suggested when results from retrospective studies are added.

Clinical TrialTemperature-related differences in mean expired pump and arterial carbon dioxide in patients undergoing cardiopulmonary bypass.
To investigate the relationship between arterial carbon dioxide (PaCO(2)) and mean expired pump CO(2) during cardiopulmonary bypass (PeCPBCO(2)) in patients undergoing cardiac surgery with CPB during steady state, cooling, and rewarming phases of CPB. ⋯ Monitoring the mean expired CO(2) value from the CPB oxygenator exhaust scavenging port with a capnography monitor provides a continuous and noninvasive data source to aid in sweep flow CPB circuit management during CPB.

Clinical TrialEffect of polymer coating (poly 2-methoxyethylacrylate) of the oxygenator on hemostatic markers during cardiopulmonary bypass in children.
Heparin and other oxygenator coatings have been used in attempts to reduce hemostatic activation during cardiopulmonary bypass (CPB). This study evaluated whether an oxygenator coated with poly 2-methoxyethylacrylate (PMEA) (X-coating; Terumo Corporation, Tokyo, Japan) would cause less activation of coagulation and fibrinolytic systems during CPB in children than a noncoated oxygenator. ⋯ Except for a somewhat higher platelet count during CPB, there was no indication that PMEA coating resulted in less activation of coagulation and fibrinolytic systems. The lower postoperative chest tube output observed after CPB with PMEA-coated oxygenators needs to be studied further.

Clinical TrialEffects of deep hypothermic circulatory arrest with retrograde cerebral perfusion on electroencephalographic bispectral index and suppression ratio.
No systematic study has been conducted to investigate effects of deep hypothermic circulatory arrest (DHCA) on electroencephalographic bispectral index (BIS) and suppression ratio (SR). Thus, the effects of DHCA were evaluated on BIS and SR. ⋯ With induction of deep hypothermia, BIS decreased in a biphasic manner to 0 at rates varying among patients. With rewarming, BIS rose again at rates extremely widely varying among patients. The rate of BIS recovery was related to duration of DHCA. BIS may be capable of conveniently tracing suppression and recovery of a part of cerebral electrical activity before, during, and after DHCA.
