OBJECTIVE To determine the predictors of core temperature on arrival in the intensive care unit (ICU) after cardiac surgery. DESIGN Prospective, randomized trial. SETTING Tertiary care medical center, operating rooms (ORs), and ICU. PATIENTS 72 patients presenting for coronary artery bypass surgery. INTERVENTIONS Randomized assignment for ambient OR(More)
BACKGROUND The Glasgow Coma Scale (GCS) is the most widely accepted scale for assessing levels of consciousness, clinical status, as well as prognosis of traumatic brain injury (TBI) patients. The Full Outline of UnResponsiveness (FOUR) score is a new coma scale developed addressing the limitations of the GCS. The aim of this prospective cohort study was to(More)
Postoperative hypothermia is common and associated with adverse hemodynamic consequences, including adrenergically mediated systemic vasoconstriction and hypertension. Hypothermia is also a known predictor of dysrhythmias and myocardial ischemia in high-risk patients. We describe a prospective, randomized trial designed to test the hypothesis that(More)
UNLABELLED Inadvertent hypothermia occurs frequently at typical ambient operating room (OR) temperatures, especially in elderly patients receiving general anesthesia. The aims of the current study were to 1) determine the incidence and magnitude of core hypothermia in an unusually warm OR environment, and 2) to assess age-related differences in(More)
Three groups each of 20 patients scheduled to undergo operations on hand or forearm, received supraclavicular brachial plexus blocks with 25 ml lignocaine 1.5%. Patients in the control group did not suffer from pain and were not asked to do muscular exercise. Patients with acute trauma of the upper limb formed the pain group and showed significantly(More)
The effect of premedication with an oral antacid (magnesium trisilicate), oral cimetidine or a combination of both was studied in 80 patients undergoing elective Caesarean section. Twenty patients served as untreated controls. Seventy per cent of the patients were in the high risk range for acid aspiration pneumonitis (pH less than 2.5 plus gastric content(More)
Systemic absorption of irrigating fluid during TUR prostatectomy under spinal anaesthesia was measured in 40 patients and correlations made under clinical, hemodynamic and laboratory observations. Results showed that the CVP monitoring is a helpful parameter in early detection of the hypervolemic hyponatremic syndrome. Serial determination of serum sodium(More)
The effects of continuous lumbar epidural analgesia for normal labour were studied in 28 women with pre-eclampsia and in 15 normal women who served as control. Maternal hemodynamics, acid-base and blood gas findings were examined. Newborn infants were assessed by Apgar Scores together with umbilical vein and artery blood gas and acid-base values. Mild(More)
This study was carried on two groups each of 10 patients undergoing major maxillofacial or orthopedic operations. Hypotensive anesthesia was conducted using SNP and labetalol. Labetalol produced hypotension without tachycardia which was evident in the SNP group. Blood sugar increased significantly in both groups. Serum insulin level decreased significantly(More)
