Effects of midline laparotomy on cough strength: a prospective study measuring cough pressure.

Background: Laparotomy is assumed to decrease cough strength due to three factors: abdominal muscle trauma, postoperative pain, and diaphragmatic dysfunction. However, the effect of trauma from laparotomy itself on strength (net of the other two factors) has not been measured to our knowledge. The aim of this study was to measure the effect of laparotomy on cough strength after first measuring the effect of epidural analgesia.

Prediction of Acute Myocardial Injury in Noncardiac Surgery in Patients at Risk for Major Adverse Cardiovascular and Cerebrovascular Events: A Multivariable Risk Model.

Background: The best use of perioperative cardiac biomarkers assessment is still under discussion. Massive postoperative troponin surveillance can result in untenably high workloads and costs for health care systems and potentially harmful interventions for patients. In a cohort of patients at risk for major adverse cardiovascular and cerebrovascular events (MACCEs), we aimed to (1) determine whether preoperative biomarkers can identify patients at major risk for acute myocardial injury in noncardiac surgery, (2) develop a risk model for acute myocardial injury prediction, and (3) propose an algorithm to optimize postoperative troponin surveillance.

Moderate sedation with dexmedetomidine-remifentanil is safer than deep sedation with propofol-remifentanil for endobronchial ultrasound while providing comparable quality: a randomized double-blind trial.

Objective: We compared dexmedetomidine-remifentanil vs. propofol-remifentanil in terms of safety and quality during sedation for Endobronchial ultrasonography (EBUS).

Methods: A randomized, double-blind trial.

Mortality and incidence of cardiovascular events in patients treated with aspirin and statins at one year after myocardial injury in noncardiac surgery: a prospective observational study.

Background: Recommendations on the diagnosis and management of myocardial injury in noncardiac surgery (MINS) show remarkable variability. Mortality reports also vary. We aimed to describe mortality and major adverse cardiovascular and cerebrovascular event (MACCE) rates in patients with silent MINS treated with postoperative aspirin-statin therapy and with cardiology follow-up.
