During spinal surgery, motor evoked potentials (MEPs) were recorded from distal upper and lower limb muscles following multipulse transcranial electrical stimulation of the cortex. Twenty-two patients, 9 of them myelopathic, were anaesthetised with propofol +/- nitrous oxide. Using trains of 3-6 pulses separated by 2 ms, consistent responses generally(More)
The "Timing Principle" utilises a single bolus of non-depolarising neuromuscular blocking drug followed by thiopentone given at the onset of clinical weakness. The purpose of this study was to compare the intubating conditions after succinylcholine and after atracurium used according to the "timing principle." Eighty patients were randomly assigned to four(More)
Eisenmenger's syndrome was originally described in 1897 and redefined by Wood in 1958. This syndrome includes pulmonary hypertension with reversed or bi-directional shunt associated with septal defects or a patent ductus arteriosus. A 27-year-old G2 PO with Eisenmenger's syndrome presented to the hospital for management at 17 weeks of pregnancy. She was(More)
Sulprostone, a synthetic prostaglandin with potent uterotonic action, has been shown to have a low complication rate in a large series. We present a case in which a bolus intravenous injection of sulprostone 30 micrograms was administered to treat postpartum haemorrhage during caesarean section. The 38-year-old patient with no previous cardiac or smoking(More)
The APACHE II scoring system was applied to 301 surgical intensive care admissions over a 9-month period. The mean age of patients admitted was 52.39 years (SD 19.3) and the mean duration of stay was 5.37 days (SD 8.93). The overall mortality was 17.27%. The mean APACHE II scores for survivors was 12.94 (SD 7.43) and non-survivors 28.19 (SD 10.43). There(More)
We have compared a new intubation manoeuvre using a fibreoptic bronchoscope with conventional blind placement of a double-lumen tube. Thirty adult patients who presented for thoracoscopy requiring one-lung ventilation underwent endobronchial intubation with a double-lumen tube inserted either in the conventional blind way or using a fibreoptic bronchoscope.(More)
Day surgery is becoming more common due to its cost effectiveness as well as patient acceptance. With increasing caseloads, there is a need to maintain quality of care. The purpose of this study is to identify the reasons for unanticipated admissions in our day surgical population, with the aim of improving efficiency of day surgical services, yet(More)
We measured the peak inflation and end expiratory pressure at the proximal and distal ends of two sizes of tracheal tube in men and women receiving positive pressure ventilation. There was a statistically significant increase in proximal inflation pressure when the smaller size of tube (6.5 mm for men, 6.0 mm for women) was used. There was no increase in(More)
Severe head injury is associated with significant morbidity and mortality. We conducted a retrospective study to assess the long-term outcome of these patients using the Glasgow Outcome Score (GOS) and evaluate the variables that might predict outcome. Data were collected from all post-traumatic neurosurgical patients with severe head injury (Glasgow Coma(More)
INTRODUCTION Morbid obesity and obstructive sleep apnoea (OSA) are increasingly encountered in anaesthetic practice today. Difficult intubation may be seen more frequently in our practice. This high-risk group may also be more prone to complications in the postoperative period. METHODS We reviewed a consecutive series of patients who had undergone(More)
