typically affects without more a segment of the hemidiaphragm
is due to incomplete muscularisation of the midriff with a thin membranous sheet replacing the vertical diaphragmatic muscle.
Over time this district stretches and on inspiration does not abridge normally.
Sudden rupture can occur by increase in intra-abdominal pressure (e.g. coughing, straining during light anesthesia or extubation etc)
True contention (if it happens) – Effects:
mass efficiency of the abdominal viscera–>instruct compression of the heart, mediastinal shift
Compression of vena cava and pulmonary veins–> impairs venous return, decreased cordial output.
So we should aver adequate depth of anaesthesia
Avoid Nitrous oxide (enlargement of intra-abdominal viscera can harm the circulation and respiration)
