We audited and analysed the adverse effects and safety of postoperative pain management on 2509 consecutive patients under care of the Acute Pain Service at a tertiary referral teaching hospital over a 32-month period. Our standard respiratory monitoring consisted of continuous pulse oximetry, hourly respiratory rate counting, sedation scoring and(More)
BACKGROUND Recent genome-wide association studies of colorectal cancer (CRC) have identified common single-nucleotide polymorphisms (SNPs) mapping to 10 independent loci that confer modest increased risk. These studies have been conducted in European populations and it is unclear whether these observations generalise to populations with different(More)
Previous studies have shown that 1 μg.kg(-1) intranasal dexmedetomidine produces significant sedation in children aged between 2 and 12 years. This investigation was designed to evaluate the onset time. One hundred children aged 1-12 years of ASA physical status 1-2 undergoing elective surgery were randomly allocated to five groups. Patients in groups A to(More)
Sixty unpremedicated healthy adult patients were studied during induction of anaesthesia with intravenous propofol delivered by a 'Diprifusor' target-controlled infusion. Bispectral index (BIS) and spectral edge frequency (SEF95) were measured concurrently with the predicted blood and effect site propofol concentrations. Logistic regression was used to(More)
BACKGROUND Midazolam is the most commonly used premedication in children. It has been shown to be more effective than parental presence or placebo in reducing anxiety and improving compliance at induction of anesthesia. Clonidine, an alpha(2) agonist, has been suggested as an alternative. Dexmedetomidine is a more alpha(2) selective drug with more favorable(More)
PURPOSE To determine the effects of desmopressin on coagulation and blood loss in patients undergoing elective partial hepatectomy. METHODS A randomized, controlled and double-blind study on 59 patients who received either 0.3 micro g x kg(-1) of desmopressin or an equal volume of normal saline (control) infused intravenously over 20 min after induction(More)
BACKGROUND The alpha2-receptor agonist, dexmedetomidine, provides sedation with facilitated arousal and analgesia with no respiratory depression. These properties render it potentially useful for anesthesia premedication, although parenteral administration is not practical in this setting. We designed this study to evaluate the sedative, anxiolytic,(More)
Serotonin dysfunction has been implicated in the pathogenesis of schizophrenia. Previous studies have shown an association between the T102C polymorphism of the 5HT2a receptor gene and schizophrenia. However, negative findings have also been reported. One possible explanation for such discrepancy is disease heterogeneity due to the current limitations in(More)
We conducted a prospective, randomized, double-blinded trial comparing preoperative application of EMLA cream and sodium chloride solution dorsal penile block (n = 31) with placebo cream and bupivacaine dorsal penile nerve block (n = 32) for postcircumcision analgesia. Pain was assessed using modified Children's Hospital of Eastern Ontario Pain Scale and(More)
Over the past two decades there has been an exponential growth in the use of thoracoscopy in children. Indeed, many advanced procedures-including lobectomy, repair of tracheoesophageal fistula, excision of mediastinal tumours, and diaphragmatic hernia repairs-can now be performed by this means in advanced paediatric surgical centres in the world.
