BACKGROUND Post-operative cognitive dysfunction (POCD) can affect 30% of orthopedic surgery patients. We hypothesized that perioperative temperature has an impact on POCD. METHODS We included 150 patients over 65 years of age scheduled for total knee replacement under spinal anesthesia. They were randomized to receive standard care (sheet cover) or active(More)
BACKGROUND Transient Neurological Symptoms (TNS) syndrome following subarachnoid anaesthesia was initially associated with hyperbaric lidocaine 50 mg/ml, but has also been reported with most local anaesthetics, including hyperbaric mepivacaine 40 mg/ml. The aim of this study was to determine the incidence of TNS after subarachnoid anaesthesia using isobaric(More)
BACKGROUND Bilateral regional brain oxygen saturation (rSO2) trends, reflecting intraoperative brain oxygen imbalance, could warn of brain dysfunction. Various types of cognitive impairment, such as memory decline, alterations in executive function or subjective complaints, have been described three months after surgery. Our aim was to explore the potential(More)
With the purpose of measuring pressure changes in the pneumatic cuffs of endotracheal tubes when the composition of the mixture of gases used for ventilation had to change for the same content, we designed a model of artificial respiration that consisted of a tube with a low pressure pneumatic cuff measuring 8.5 mm in inner diameter introduced in a replica(More)
To examine the possible interaction between diclofenac and midazolam, 20 patients undergoing orthopedic or traumatologic surgery were studied. All were anesthetized with 0.3 mg/kg intravenous midazolam after having been premedicated randomly with either placebo (control group, n = 10) or with 1 mg/kg intravenous diclofenac (n = 10). Anesthetic(More)
The effects of anesthetic premedication with diazepam and phentanyl on the arterial oxyhemoglobin saturation (SpO2) were monitored with a pulsioximeter (BIOX 3700, Ohmeda) in 83 patients scheduled for traumatologic and orthopedic surgery who had baseline SpO2 higher than 95%. Premedication was carried out with phentanyl (0.1 mg) and diazepam (2.5 mg(More)
The hypnotic dose of midazolam administered in continuous perfusion was investigated in 76 patients undergoing programmed traumatologic or orthopedic surgery. In all cases an infusion of midazolam at a rate of mg-1 kg-1 h-1 was administered until patients closed eyes but opened them under auditive stimuli (hypnotic dose of midazolam). This dose was 5.25 +/-(More)
