Effect of acute hypocapnia on some aspects of renal function in anaesthetized dogs.
Hypocapnia was induced in dogs lightly anaesthetized with nitrous oxide and fentanyl. Measurements were made of estimated renal plasma flow (ERPF), glomerular filtration rate, vascular resistance and urine production. During the (short) duration of the experiments hypocapnia was found to be associated with ERPF twice that during normocapnia. Glomerular filtration rate and urine output were increased by hypocapnia in an approximately similar proportion, whilst renal vascular resistance halved. Though some of the experimental animals had a degree of metabolic acidosis this was thought not to have greatly influenced the results.

Postoperative analgesia.
Postoperative analgesia both by drugs and regional techniques is reviewed. In the United Kingdom in the last 25 years or more there has been little advance on either front. Some marginal improvement in regard to drugs might be brought about by better education of both doctors and nurses and better patient contact. Extradural analgesia and intercostal block do not offer a complete solution, though a judicious increase in the use certainly of the former might be beneficial. The problem awaits a radical new approach.

Postoperative pain in ophthalmology.
A survey of 100 consecutive patients suggests that, overall, ophthalmic surgery is not as painful postoperatively as general surgery. Cataracts are largely painless. Retinal detachments may sometimes give rise to postoperative pain like that in general surgery, but the numbers available are not yet sufficient for statistical analysis. Routine postoperative analgesia for encirclement procedures in retinal detachment patients should be considered for at least the first 18 hours after operation.

The circle system without absorber. Use with controlled ventilation.
An investigation is described into the performance of two types of circle system used without a carbon dioxide absorber in both the laboratory and in the operating theatre with controlled ventilation. The newer system was found to be more efficient than the old but in both types of system the tidal volume was found to be very important, a large tidal volume resulted in increased efficiency. The possibility of predicting arterial blood carbon dioxide using this system is briefly discussed, and rules are suggested for the use of the system.

Phillip Gett memorial lecture awareness in anaesthesia.
An attempt is made to assess the importance of awareness and dreaming in patients subjected to light anaesthesia with muscle relaxants. Frank awareness is probably an uncommon event if the anaesthetic be given competently, but unpleasant dreams can, in some circumstances, be significant.
