Singapore SPICE: sedation practices in intensive care evaluation in Singapore - a prospective cohort study of the public healthcare system.

Introduction: A study was conducted to describe the sedation practices of intensive care units (ICUs) in Singapore in terms of drug use, sedation depth and the incidence of delirium in both early (< 48 hours) and late (> 48 hours) periods of ICU admission.

Methods: A prospective multicentre cohort study was conducted on patients who were expected to be sedated and ventilated for over 24 hours in seven ICUs (surgical ICU, n = 4; medical ICU, n = 3) of four major public hospitals in Singapore. Patients were followed up to 28 days or until ICU discharge, with four-hourly sedation monitoring and daily delirium assessment by trained nurses.

Massaging the outcome: an unusual presentation of pulmonary embolism.

A 56-year-old man with a previous deep venous thrombus presented with dyspnoea after a leg massage. A transthoracic echocardiogram demonstrated a "worm-shaped" right atrial embolus, most probably a femoral cast. A pulmonary artery angiogram confirmed a large wedge-shaped perfusion defect caused by a pulmonary embolus.
