Period-dependent Associations between Hypotension during and for Four Days after Noncardiac Surgery and a Composite of Myocardial Infarction and Death A Substudy of the POISE-2 Trial

Background The relative contributions of intraoperative and postoperative hypotension to perioperative morbidity remain unclear. We determined the association between hypotension and a composite of 30-day myocardial infarction and death over three periods: (1) intraoperative, (2) remaining day of surgery, and (3) during the initial four postoperative days.Methods This was a substudy of POISE-2, a 10,010-patient factorial-randomized trial of aspirin and clonidine for prevention of myocardial infarction. Clinically important hypotension was defined as systolic blood pressure less than 90 mmHg requiring treatment. Minutes of hypotension was the exposure variable intraoperatively and for the remaining day of surgery, whereas hypotension status was treated as binary variable for postoperative days 1 to 4. We estimated the average relative effect of hypotension across components of the composite using a distinct effect generalized estimating model, adjusting for hypotension during earlier periods.Results Among 9,765 patients, 42% experienced hypotension, 590 (6.0%) had an infarction, and 116 (1.2%) died within 30 days of surgery. Intraoperatively, the estimated average relative effect across myocardial infarction and mortality was 1.08 (98.3% CI, 1.03, 1.12;P

AbstractBeta-adrenergic blockers ( β-blockers) are clearly indicated for the long-term treatment of patients with systolic heart failure and post-acute myocardial infarction. Early small-scale studies reported their potential benefits for perioperative use; subsequent randomized controlled trials, however, failed to reproduce earlie r findings. Furthermore, their role in reducing major postoperative cardiac events following noncardiac and cardiac surgery remains controversial. This case-based review presents an overview of contemporary literature on perioperative β-blocker use with a focus on data available since...

ConclusionsThe overall VTE rate after CABG has been low. However, the condition has been associated with worse 30-day postoperative outcomes and complications. The independent predictors of VTE development included a history of bleeding disorders, congestive heart failure in the 30 days before surgery, and operative time of ≥310 minutes. Understanding these risk factors should aid physicians in the decisions regarding prophylaxis and treatment.

HISTORICALLY, carotid endarterectomy (CEA) surgery has generated several disputes regarding the choice of anesthesia provided and intraoperative neuromonitoring. The landmark General Anesthesia versus Local Anesthesia trial,1 which included 3,526 patients, showed no difference in the occurrence of stroke, myocardial infarction, or death at 30 days after surgery with respect to either local or general anesthesia. Harky et al.2 conducted a systematic review and meta-analysis of general versus local anesthesia in CEA surgery and concluded that each of the anesthetic techniques was noninferior to one another.

CONCLUSIONS: The evidence for early all-cause mortality with perioperative beta-blockers was uncertain. We found no evidence of a difference in cerebrovascular events or ventricular arrhythmias, and the certainty of the evidence for these outcomes was low and very low. We found low-certainty evidence that beta-blockers may reduce atrial fibrillation and myocardial infarctions. However, beta-blockers may increase bradycardia (low-certainty evidence) and probably increase hypotension (moderate-certainty evidence). Further evidence from large placebo-controlled trials is likely to increase the certainty of these findings, and...

r M Abstract OBJECTIVE: Fast track concepts are used to reduce the risk of perioperative and postoperative complications after total knee arthroplasty. INDICATIONS: The described concepts are used for patients with indications for the implantation of a total knee prosthesis. CONTRAINDICATIONS: Contraindications for fast track concepts are aged patients, dementia, American Society of Anesthesiologists (ASA) grade IV and implantation of large revision or tumor prostheses. Contraindications for tranexamic acid are bleeding in the urinary tract, caution in cases of known epilepsy, individual risk assessment ...
