Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of two ventilators used with the T-piece in paediatric anaesthesia.
The Nuffield 200 ventilator was compared with a new valveless ventilator (CW 200) in 20 children undergoing general anaesthesia for paediatric surgery. The new ventilator incorporates design features which overcome the main disadvantages of the Nuffield 200 and make it an inherently safer machine. At identical ventilator settings it produced a significantly greater tidal volume with a reduction in end-tidal carbon dioxide partial pressure. This may have advantages in avoiding pulmonary barotrauma in children.

Randomized Controlled Trial Comparative Study Clinical TrialPreanesthetic medication with rectal midazolam in children undergoing dental extractions.
Three different dosages (0.25, 0.35, and 0.45 mg/kg) of rectally administered midazolam were compared with each other and with placebo for preanesthetic medication in children undergoing dental extractions. Eighty patients between the ages of 2 and 10 years were randomly allocated into four groups in this double-blind study. ⋯ A high prevalence (23%) of disinhibition reactions was observed, particularly in the 0.45 mg/kg group. For this reason, 0.25 or 0.35 mg/kg appears to be the dose of choice when rectal midazolam is used for premedication in children.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial[Postoperative course and endocrine stress reaction of geriatric patients with para-articular hip fractures. Prospective randomized study comparing spinal anesthesia and halothane intubation narcosis].
During a period of one year, all patients above the age of 60 with surgical repair of fractured neck of femur were investigated in a prospectively randomized design. A follow-up study included a total number of 56 patients, 32 were allocated to halothane anaesthesia with intubation, 24 received spinal anaesthesia. In addition, 15 patients of the halothane group and 17 patients with spinal anaesthesia were investigated with regard to endocrine stress response. ⋯ Noradrenaline was markedly increased even before the operation, and concentrations increased in the halothane group in the course of the operation. There was a linear correlation to time between accident and the beginning of the operation. With regard to endocrine parameters, prompt surgical treatment is beneficial.

Randomized Controlled Trial Comparative Study Clinical TrialA randomized comparison of manipulation of the fractured nose under local and general anaesthesia.
Reduction of simple nasal fractures may be performed under local or general anaesthesia: the latter is by far the most popular method in Britain, though why is hard to define. We have attempted to compare the 2 approaches by means of a randomized, prospective trial. ⋯ Analysis of results at 4 h and 8 weeks post-operatively showed no significant benefit conferred by fracture reduction under general anaesthesia as opposed to local anaesthesia with respect to post-operative airway patency or cosmesis. It is suggested that significant benefits can be obtained in terms of patient convenience and cost effectiveness if nasal fractures are reduced under local anaesthesia as an outpatient procedure.
