A battery of neuropsychological measures considered sensitive to dysfunction in prefrontal or temporal cortices was administered to patients with borderline personality disorder (BPD) and healthy controls. BPD patients exhibited striking deficits on measures of nonverbal executive function and nonverbal memory but were unimpaired on tests of alternation(More)
The predictive performance of a 'Diprifusor' target controlled infusion system for propofol was examined in 46 patients undergoing major surgery, divided into three age groups (18-40, 41-55 and 56-80 years). Measured arterial propofol concentrations were compared with values calculated (predicted) by the target controlled infusion system. Performance(More)
The effect of pretreatment with fentanyl on the pharmacokinetics of a single bolus of propofol was studied in 17 female patients (mean age 35 yr), ASA grade I. Eight patients received fentanyl 1.5 micrograms kg-1 5 min before induction of anaesthesia. In all patients anaesthesia was induced with propofol 2.5 mg kg-1 and maintained with halothane and nitrous(More)
The obese patient is likely to have pre-operative impairment of cardiovascular and respiratory function. These impairments will tend to increase in the per- and post-operative period and place the patient at risk of myocardial ischaemia and hypoxaemia. The physical effects of obesity mean that all patients require endotracheal intubation during anaesthesia(More)
OBJECTIVES (1) To determine whether pre-operative assessment carried out by an appropriately trained nurse (ATN) is equivalent in quality to that carried out by a pre-registration house officer (PRHO). (2) To assess whether pre-assessments carried out by ATNs and PRHOs are equivalent in terms of cost. (3) To determine whether assessments carried out by ATNs(More)
In a randomised, placebo-controlled, double-blind study involving 81 patients undergoing total abdominal hysterectomy, the postoperative analgesia provided by transdermal fentanyl given at 25, 50, or 75 micrograms.h-1 for 72 h was compared with a placebo group. The efficacy of the Transdermal Therapeutic System was related to the rate of fentanyl delivery,(More)
Morbid obesity is associated with a reduction in time to desaturate during apnoea following standard pre-oxygenation and induction of anaesthesia. We have compared the effects of using 7.5 cmH2O of continuous positive airway pressure (CPAP) for pre-oxygenation with a standard technique using a Mapleson A breathing system, in 20 morbidly obese women. In a(More)
OBJECTIVE To determine whether preoperative assessments carried out by appropriately trained nurses are inferior in quality to those carried out by preregistration house officers. DESIGN Randomised controlled equivalence/non-inferiority trial. SETTING Four NHS hospitals in three trusts. Three of the four were teaching hospitals. PARTICIPANTS All(More)
The newer neuromuscular blocking drugs include vecuronium and atracurium. Vecuronium is a competitive neuromuscular blocking drug with a steroid nucleus. A dose of 0.1 mg/kg has an onset time of 2 minutes and provides surgical paralysis for 20 minutes. Recovery to 90% twitch height occurs in 40 to 50 minutes. Vecuronium has few adverse effects and its use(More)
The effect of changing the rate of infusion of propofol for induction of anaesthesia was studied in 60 elderly patients. Propofol was administered at 300, 600 or 1200 ml h-1 until loss of consciousness (as judged by loss of verbal contact with the patient) had been achieved. The duration of induction was significantly longer (P less than 0.001) with the(More)
