    Notes: Twenty-six patients received oral temazepam and subsequently spinal anaesthesia. Blood and lumbar cerebrospinal fluid temazepam levels were measured together with the degree of sedation. The plasma and cerebrospinal fluid concentrations correlated well with the temazepam dose but even better with the weight standardised dose (r = 0.65, p = 0.0003 and r = 0.75, p = p = 0.00001 respectively). Both the plasma and cerebrospinal fluid concentrations of temazepam were correlated with the patient's sedation (r = 0.42 p = 0.037, and r = 0.46 p = 0.021 respectively), but neither was strong. Thus, although the drug concentration at the receptor may be a major factor in producing sedation, others factors, possibly the receptor population or their responsiveness, are also important contributors.

    Notes: In a double-blind controlled trial of male patients undergoing transurethral resection of the prostate, oral lorazepam was assessed against a placebo. The same anaesthetist performed all spinal blocks and made all assessments. The patients who received lorazepam had substantial amnesia for the operation and were drowsier, but remained cooperative during the procedure. Patient anxiety as assessed by the anaesthetist and as recalled by the patient was decreased, although anxiety assessment by linear analogue was the same for both groups. Lorazepam significantly increased the patient acceptability of spinal anaesthesia.

    Notes: The clinical pharmacodynamics of temazepam were investigated in patients who received spinal anaesthesia. Total plasma and cerebrospinal fluid temazepam concentrations were measured and correlated with the clinical effects. Sedation was measured by three separate methods. None, including an aggregated score of all three measures, was correlated closely with either the plasma or the cerebrospinal fluid levels (p = 0.86 and 0.12 respectively). Anxiety was measured before and after premedication. The two scores were correlated but the change in anxiety after premedication did not correlate with either the plasma or the cerebrospinal fluid concentrations (p = 0.11 and 0.45 respectively). Short-term memory was measured before and after premedication. The decline in short-term memory ability was moderately well correlated with both the plasma and the cerebrospinal fluid levels (p = 0.0005 and 0.013 respectively). With temazepam, the variation in sedative and anxiolytic effects between subjects is explained not by differences in pharmacokinetics but rather by differences in the pharmacodynamic response. Because sedative and anxiolytic effects are poorly correlated, but the amnesic effect is well correlated with temazepam concentrations, different sites of action for these effects are suggested.

    Notes: Accidental bronchial intubation was examined in the first 3947 cases reported to the Australian Incident Monitoring Study and was found to have accounted for 154 (3.7%) of the total incidents reported. Most incidents were detected in the operating theatre (93.5%) and during maintenance of anaesthesia (77.9%), by unexplained oxygen desaturation alone (63.6%). Capnography remained normal or unremarkable during 88.5% of the episodes. One-third of cases were associated with head or neck surgery and possible flexion of the patient’s head. A RAE tube was used in 20% of incidents, a greater frequency than occurred in the study overall. A third party was implicated in 36 (23.4%) of cases. Ninety per cent of cases were considered preventable. Major morbidity occurred in three cases and unplanned intensive care admission was required in a further five. Almost two-thirds (61.1%) of the incidents might have been avoided by the proposed markings on the tracheal tube. We conclude that when arterial desaturation occurs at any stage during anaesthesia the possibility of bronchial intubation must be considered. Asymmetrical ventilation may be difficult to detect clinically and in most cases there is no change in capnography.

    Notes: Hyperkalaemic periodic paralysis is the rarer of the two forms of potassium-associated familial paralysis. We report a family with hyperkalaemic periodic paralysis with paramyotonia and the anaesthetic management of four affected members. In three of these, paralytic episodes had been precipitated by previous anaesthesia, but this was avoided in the anaesthetics described. We conclude from our experiences that with depletion of potassium before surgery, prevention of carbohydrate depletion, avoidance of potassium-releasing anaesthetic drugs and maintenance of normothermia, patients with hyperkalaemic periodic paralysis can be anaesthetised without complications. We have no evidence that they exhibit abnormal sensitivity to nondepolarising neuromuscular relaxants.

    Notes: The volume of the mouth and pharynx was measured in 20 cadavers and ranged from 25 to 202 ml with a median value of 87 ml, a mean of 90.7 ml and a geometric (logarithmic) mean of 78.3 ml. The volume that encompasses 99% of the normal population is estimated as 215 ml if the assumption of a normal Gaussian distribution is made, or 349 ml if a log-normal distribution is assumed. Collection containers in suction equipment intended for removing vomit from the pharynx and mouth in adults should have a useable volume of at least 500 ml.

    Notes: We examined the effect of no music, classical music or rock music on simulated patient monitoring. Twenty-four non-anaesthetist participants with high or low levels of musical training were trained to monitor visual and auditory displays of patients' vital signs. In nine anaesthesia test scenarios, participants were asked every 50–70 s whether one of five vital signs was abnormal and the trend of its direction. Abnormality judgements were unaffected by music or musical training. Trend judgements were more accurate when music was playing (p = 0.0004). Musical participants reported trends more accurately (p = 0.004), and non-musical participants tended to benefit more from music than did the musical participants (p = 0.063). Music may provide a pitch and rhythm standard from which participants can judge changes in vital signs from auditory displays. Nonetheless, both groups reported that it was easier to monitor the patient with no music (p = 0.0001), and easier to rely upon the auditory displays with no music (p = 0.014).
