Randomized Controlled TrialElectrocardiograph changes, troponin levels and cardiac complications after orthopaedic surgery.
The relationship between electrocardiograph (ECG) changes and troponin levels after the emergency orthopaedic surgery are not well characterised. The aim of this study was to determine the correlation between ECG changes (ischaemia or arrhythmia), troponin elevations perioperatively and cardiac complications. ⋯ Electrocardiograph changes do not necessarily accompany troponin elevations after the emergency orthopaedic surgery but are more likely to have higher troponin levels. The best predictor of postoperative cardiac complications is troponin elevation.

Randomized Controlled TrialTwo strategies to intensify evidence-based medicine education of undergraduate students: a randomised controlled trial.
Undergraduate evidence-based practice (EBP) is usually taught through standalone courses and workshops away from clinical practice. This study compared the effects of 2 clinically integrated educational strategies on final year medical students. ⋯ Structured case conference, when compared to the didactic lectures, significantly improved EBP-K and EBP-P for final year medical students.

Randomized Controlled Trial Clinical TrialImpact of a pharmacist consult clinic on a hospital-based geriatric outpatient clinic in Singapore.
We study the impact of a pharmacist consult clinic on the care of elderly outpatients based on the Health Belief Model that the perceived benefits (improvement in medication knowledge, clinical status and perception) and attached barriers (cost and number of medication and adverse drug reactions) can influence health behaviour (medication compliance). ⋯ The addition of a pharmacist consult clinic to the management of selected geriatric outpatients can improve compliance, with the attendant benefits of improving medication knowledge, cost avoidance and reducing residual adverse drug reactions.

Randomized Controlled Trial Clinical TrialIntravenous regional anaesthesia using lignocaine and tramadol.
This prospective, randomised, double-blind study was designed to assess if the addition of 50 mg tramadol to 30 mL 0.5% lignocaine would improve the efficacy of intravenous regional anaesthesia. ⋯ There is a positive trend that tramadol might improve the quality of intravenous regional anaesthesia.

Randomized Controlled Trial Clinical TrialEffect of different endotracheal suctioning systems on cardiorespiratory parameters of ventilated patients.
We conducted this prospective randomised cross-over study to evaluate the effect of closed system (CS) versus open system (OS) endotracheal suctioning on heart rate (HR), mean arterial pressure (MAP), respiratory rate (RR), oxygen saturation (SpO2) and electrocardiogram (ECG) rhythm of patients on mechanical ventilation. ⋯ Our study shows that OS suctioning results in more adverse changes in cardiorespiratory parameters compared to CS suctioning.
