Randomized Controlled Trial Clinical Trial
The cardiovascular responses to double lumen endobronchial intubation and the effect of esmolol.
The cardiovascular responses to double lumen endobronchial intubation and the effect of esmolol were examined in two groups of 10 ASA 2 & 3 patients undergoing pulmonary surgery in a double blind, placebo-controlled study. Endobronchial intubation was associated with a significant increase in arterial pressure and heart rate (p = 0.004), and a significant increase in plasma noradrenaline concentrations (p < 0.01) in the control group. ⋯ The increase in plasma noradrenaline concentrations was significantly greater (p < 0.05) in the esmolol group. The pressor response to endobronchial intubation in this study was of a similar magnitude to that known to occur in response to tracheal intubation.

Randomized Controlled Trial Clinical Trial
Dreams, images and emotions associated with propofol anaesthesia.
One hundred and twelve patients scheduled for day case varicose vein surgery were randomly allocated to one of three groups: total intravenous anaesthesia with propofol, propofol induction followed by inhalational anaesthesia with nitrous oxide and isoflurane or thiopentone induction followed by inhalational anaesthesia with nitrous oxide and isoflurane. Assessments were made in the recovery room of the incidence of dreaming, the content of the dreams and the emotional status of the patients. ⋯ However, despite the large number of case reports of sexual imagery following propofol anaesthesia and despite the two groups who had received propofol experiencing significantly greater happiness upon recovery than the thiopentone group, there were no appreciable differences in the sexual content of the dreams. Each group had only a small number of dreams even remotely related to sex.

A patient with a previous surgical history of a cleft lip and palate repair and a pharyngeal flap pharyngoplasty was admitted for repair of mandibular prognathism. Following induction of anaesthesia, it was impossible to advance the nasotracheal tube into the oropharynx. Using a dental mirror and retrograde tracheal intubation equipment, under direct vision, the nasotracheal tube was finally advanced into the oropharynx.
