An understanding of the physiological changes seen in late pregnancy, avoidance of the supine posture, together with routine administration of alkali during labour and a careful anaesthetic technique will enable the anaesthetist to avoid many of the potential problems of obstetric anaesthesia.
The anaesthetist is ultimately responsible for ensuring that the machine used for a particular anaesthetic is in a safe condition before the procedure is commenced. He can only do this if he understands how the machine operates, and has established for himself a checking procedure which will uncover potentially lethal faults in the apparatus. The importance of a systematic and thorough check cannot be overemphasized. Continuing monitoring of the machine and the patient during the anaesthetic is mandatory.
This simple apparatus demonstrates that when a quantity of volatile agent is added to a solvent system the partial pressure exerted is inversely proportional to the solubility of the agent in the solvent.
The satisfactory organization of an educational exercise is dependent on the organizer having a precise understanding of the needs of his students, their present level of knowledge and understanding, the motives which govern their will to learn, and on the organizer's ability to draw together people with intellectual resources capable of satisfying those needs of the students. Both students and tutors must be placed in an environment which encourages communication and interaction and adequate physical resources for teaching must be provided.
A teaching aid is exactly what it says it is--an aid to teaching. No matter how exciting the aid may be, its production is not an end in itself, merely a means to an end. Teaching aids are most effective and can be best justified when a need for them has been demonstrated and when they can be shown to clarify the teaching of points and problems which students have formerly found difficult to understand. The best teaching aids are the result of a combination of imagination and enthusiasm. Aids should always be evaluated to determine whether the costs of production are justified by an improvement in learning.
