Multicenter StudySurvival after primary breast cancer surgery following propofol or sevoflurane general anesthesia - aretrospective, multicenter, database analysis of 6,305 Swedish patients.
Retrospective studies indicate that the choice of anesthetic can affect long-term cancer survival. Propofol seems to have an advantage over sevoflurane. However, this is questioned for breast cancer. We gathered a large cohort of breast cancer surgery patients from seven Swedish hospitals and hypothesized that general anesthesia with propofol would be superior to sevoflurane anesthesia regarding long-term breast cancer survival. ⋯ It seems that propofol may have a survival advantage compared with sevoflurane among breast cancer patients, but the inherent weaknesses of retrospective analyses were made apparent.

Preoperative transthoracic echocardiography in ambulatory surgery- a cross sectional study.
Cardiac disease and aberrations in central volume status are risk factors for perioperative complications, and should be identified prior to surgery. This study investigated the benefit of transthoracic echocardiography (TTE) for pre-operative identification of cardiac disease and hypovolemia in ambulatory surgery. ⋯ In this ambulatory surgical cohort, a high prevalence of pre-operative LV dysfunction and aberrations in volume status was observed. The results demonstrate that pre-operative TTE contributed valuable hemodynamic information. The standard pre-operative assessment for this cohort might need to be revised.

Observational StudyIntensive care patient survival afterlimiting life-sustaining treatment-the FINNEOL*national cohort study.
Few studies have examined survival in intensive care unit (ICU) patients after the restriction of life-sustaining treatment (LST). We aimed to analyse independent factors associated with hospital and 12-month survival rates in ICU patients after treatment restrictions. ⋯ Survival among ICU patients with limited treatment was higher than expected. Advanced age was not associated with higher mortality, potentially because treatment restrictions may be set more easily for older patients.

Effects of anesthetics on postoperative 3-month neuroendocrine function after endoscopic transsphenoidal non-functional pituitary adenoma surgery.
Anesthetic techniques can affect perioperative neuroendocrine function. The objective of this study was to compare 3-month post-operative neuroendocrine functional outcomes between sevoflurane and propofol anesthesia in patients undergoing endoscopic transsphenoidal surgery (ETS) for removal of non-functional pituitary adenomas (NFPAs) retrospectively. ⋯ In patients undergoing ETS for removal of NFPAs, the effects of both sevoflurane-remifentanil and propofol-remifentanil anesthetic techniques on post-operative 3-month neuroendocrine functional outcomes were similar, suggesting that propofol and sevoflurane can be freely used in such patients in terms of post-operative intermediate-term neuroendocrine functional outcome.

No evidence of cardiac stunningor decoupling immediately after cardiopulmonary bypass for elective coronarysurgery.
There is significant uncertainty regarding the timing of onset of cardiovascular stunning after cardiac surgery. Cardiovascular stunning is affecting both contractility (Ees) and arterial load. Arterial load may be represented by arterial elastance (Ea) and participates in ventriculo-arterial coupling through the Ea/Ees ratio, giving information on efficiency and performance. An alternative approach to ventriculo-arterial interaction is oscillatory power fraction (OPF). The aim of this study was to investigate the immediate beat-to-beat effects of on-pump coronary artery bypass graft (CABG) surgery on contractility, cardiac power parameters, arterial load and ventriculo-arterial coupling as well as classical haemodynamic parameters. ⋯ There was no evidence for clinically relevant cardiac stunning or altered arterial load immediately after cardiopulmonary bypass for CABG surgery. The unchanged Ea/Ees ratio and OPF are indicating unchanged cardiac efficiency before and after cardiopulmonary bypass. This indicates that in elective CABG patients cardiovascular stunning is perhaps a phenomenon of inflammation and not immediate ischaemia-reperfusion injury or mechanical handling.
