Although much has been written relative to the role of pneumoperitoneum in the treatment of pulmonary tuberculosis, there still remain many unanswered questions pertaining to its therapeutic efficacy, the incidence of abdominal fluid formation, complications, the optimum position of the elevated leaves of the diaphragm, the duration of treatment, etc. Similarly, much has been written relative to the best site for inserting the needle into the abdominal wall or even the lower intercostal spaces. It is believed worth while to mention one aspect of technique which has rarely been presented. As a rule, patients about to receive a pneumoperitoneum refill lie on the back with or without a pillow under the head. Some are tense, some are relaxed, others tend to push the abdominal wall towards the needle. Rarely does the operator pay any attention to the phase of respiration during which the needle is introduced into the abdominal cavity. The illustrations shown graphically portray the differences in the height of the abdominal air space at the end of inspiration as compared with the end of expiration. The patients were advised to “take a deep breath, hold it, push.” The needle was then quickly inserted through the abdominal wall. it is well known that on ‘inspiration the lungs expand, the diaphragm descends, and the contained abdominal air pushes the abdominal wall outward. It will be noted from the illustrations that the increase in height of the abdominal air space at the end of inspiration may reach approximately 40 to 50 per cent. Marmion’ reported a difference dominal air space on deep inspiration We have found that the difference deep inspiration and deep expiration

While the illustrations depict patients over a period of months, it is suggested of the abdominal air space plays a more nique factor in administering air refills to of pneumoperitoneum induction, and also

SUMMARY

As shown in the illustrations, the height of the abdominal air space in a patient with artifically induced pneumoperitoneum is increased on deep inspiration as compared with expiration. It is therefore concluded that for those patients receiving pneumoperitoneum refills in whom an appreciable air space is not present, the insertion of the needle at the end of a deep inspiration is a safer procedure to reduce the danger of injuring the abdominal viscera. RESUMEN

Corno se ha mostrado en las ilustraciones Ia altura del aire en el neumoperitoneo artificial, aumenta en Ia inspiraci#{243}n profunda en comparaci#{243}n con la expiraci#{243}n. Se concluye por tanto para los enfermos que reciben neumoperitoneo en los que una capa de aire no es apreciable, la inserci#{243}n de Ia aguja al final de una inspiraci#{243}n profunda es un procedimiento m#{225}s seguro para reducir el peligro de lesionar las vIsceras abdominales. RESUME

Comme ii est montr#{233} sur les planches, l’importance de Ia cavit#{233}a#{233}rique de l’abdomen chez un malade trait#{233} par pneumop#{233}ritoine est infiniment plus #{233}lev#{233}e dans l’inspiration profonde que dans l’expiration. Ii en r#{233}sulte que pour les malades a qui l’on insuffie un pneumop#{233}itoine, lorsqu’il n’y a pas de cavit#{233}gazeuse suffisante, il est plus sflr de faire Ia piqiire a Ia fin d’une inspiration profonde, afin de r#{233}duire le danger be blesser les visc#{232}res abdominaux.
