Cardiopulmonary resuscitation: a survey of standards among junior hospital doctors.

The theoretical knowledge of cardiopulmonary resuscitation of 50 junior hospital doctors was examined, and an attempt made to assess their practical ability to manage a collapsed patient. Major defects were found in both the doctors' theoretical knowledge and their practical abilities. Only 8% were able to manage a cardiopulmonary arrest adequately. Suggestions are made as to how standards might be improved.

Anaesthesia for myringotomy. The effect of nitrous oxide and intermittent positive pressure ventilation in children with secretory otitis media.

The effect of two methods of anaesthesia on the findings at myringotomy in children with secretory otitis media was studied. One group of patients spontaneously breathed a mixture of nitrous oxide, oxygen and halothane whereas a second group had assisted ventilation, tracheal intubation and breathed a mixture of halothane and oxygen. Nitrous oxide diffused significantly into middle ears which had gas under reduced pressure (with or without fluid present) when compared with normal ears (p less than 0.05). Assisted ventilation prior to tracheal intubation did not introduce gas into the middle ear. It is concluded that impedance audiometry is a reliable method of assessing the middle ear prior to surgery.

Neurogenic pulmonary oedema.

Neurogenic pulmonary oedema is a not uncommon condition with a mortality that may exceed 90%. A fatal case in a 17-month-old child is reported. The literature is reviewed and current theories of the pathogenesis presented. Suggestions are made on how the condition might best be managed.

Anaesthesia and tympanometry.

Nitrous oxide and intermittent positive pressure respiration prior to intubation raised the middle ear pressure in children with normal ears. In children with secretory otitis media, nitrous oxide was responsible for aeration alone and this was seen only in children with some gas present prior to surgery. Wide range tympanometry accurately predicted the findings at myringotomy.

Nitrous oxide and middle ear pressure. A study of induction methods in children.

The effects of different methods of induction of anaesthesia on middle ear pressure were investigated in healthy children. An increase in middle ear pressure associated with positive pressure ventilation with a bag and mask was demonstrated. When nitrous oxide was used, middle ear pressure increased by 39 mmH2O/minute in spontaneously breathing patients and 63 mmH2O/minute in those who were ventilated. Maximum pressures, with venting through the Eustachian tube, could be reached within 5 minutes in the latter group.
