Childhood cancer survivors: attained adult heights. Compared with sibling controls.

As part of a large collaborative study, the authors administered a pretested questionnaire to 62 childhood and adolescent cancer survivors and 62 same-sex sibling controls. The authors requested information regarding attained adult height on the questionnaire. Mean adult height of survivors (172.2 cm) was less than that of controls (174.1 cm), at a borderline significant difference of p = 0.0757. Multivariate analysis examined four potential, independent variables as possible predictors of this difference. The presence of brain tumor (vs. nonbrain tumor) (p less than .0001) and diagnosis at an early age (less than or equal to 8 years vs. 9-15 years) (p = .05) were factors significantly related to the differential; sex of patient and type of therapy were not. Our findings thus identify malignancy site and age at diagnosis as important predictors of adult height in childhood and adolescent cancer survivors.

Dental damage during anaesthesia and surgery.

A review of the Accident Compensation Corporation (ACC) files on dental damage following anaesthesia or surgery was undertaken along with a survey of New Zealand anaesthetists asking about their practice with respect to protection of teeth during anaesthesia. These results confirm that damage is relatively common and that the majority of damaged teeth (62%) were known to have been previously restored, or weakened through periodontal disease prior to the damage occurring. The anaesthetists surveyed thought that dental damage was even more common than shown from the ACC records, and yet the vast majority of them did not routinely use specific protective guards and 45% of them did not ever use protective guards of any type.

Outpatient anaesthesia for dilatation and curettage.

An anaesthetic technique (caudal blockade with chloroprocaine and intravenous propanidid) for patients having dilatation and curettage of the uterus as outpatients is presented, and a prospective series of patients reviewed. Results show a high level of patient satisfaction with the technique and a low incidence of side effects.

Department staffing in anaesthesia.

A survey about staffing of departments of anaesthesia in teaching hospitals, and about the duties of their anaesthetists, showed similar results to a preliminary survey (Baker 1978) which suggested that two-thirds of Australasian departments were understaffed by senior specialists. The survey also showed a high ratio of one, of trainees to senior specialists, which will soon oversupply specialists in practice if allowed to continue.

Staffing in anaesthesia in Australasia.

A survey of Australasian departments of anaesthesia was undertaken. Recommendations for ideal staffing are made and the extent to which present staffing satisfies these recommendations is described.

No ignition risk with hyperbaric enflurane.

A series of experiments was undertaken with Enflurane under hyperbaric conditions to determine whether or not it was explosive under these conditions. No risk of detonation was shown with concentrations of Enflurane up to 5% in either oxygen or nitrous oxide mixtures under conditions of hyperbaria to 3 A.T.A. (Atmospheres Absolute).

Effects of varying inspiratory flow waveform and time in intermittent positive pressure ventilation. I: Introduction and methods.

A general review of the physiological alterations with artificial ventilation is presented with particular emphasis on the alteration of inspiratory time and flow waveform. The general methods and physiological calibration procedures used in a more elaborate study of inspiratory time and waveform effects are described, with the results of testing these methods showing that the model is satisfactory.

Effects of varying inspiratory flow waveform and time in intermittent positive pressure ventilation. III: Blockade of the autonomic nervous system.

The autonomic nervous system was blocked in dogs which were exposed to independent alterations in inspiratory flow waveform and time whilst being ventilated artificially at a constant volume and frequency. There were statistically significant differences in cardiac output between the control and blocked states, but these differences were not of marked physiological significance. Alteration in inspiratory waveform or time in the blocked animals did not alter cardiac output significantly.

The treatment of flail chest injury.

Flail chest injuries are traditionally managed by long-term artificial ventilation, which in itself is hazardous and expensive. A more conservative therapeutic regime is described, and the results of this regime are compared with those following the previous traditional regime used in the Respiratory Unit, Royal Brisbane Hospital. The place of artificial ventilation in relation to spontaneous ventilation is redefined in the context of this new regime.

Post-operative flow-volume loops.

A study of flow-volume curves pre- and post-operatively demonstrated a marked difference between bronchitic and non-bronchitic patients. All bronchitic patients showed lower flow rates at low lung volumes post-operatively, when compared with their pre-operative values. Non-bronchitic patients all had higher flow rates for the same comparison.

Post operative pulmonary compliance.

Lung compliance was studied pre-operatively and post-operatively in a group of patients having abdominal surgery. Lung compliance was shown to be markedly reduced post-operatively especially in the patients with chronic bronchitis.
