[The risk of cardiac arrest during laparoscopy. A study of 50,000 laparoscopies and animal experimentation].
In a French national enquiry into 50,000 laparoscopies it emerges that the number of cardiac arrests works out at 1 in 2,000. The percentage of reversible cardiac arrests was 1 in 2500 and of irreversible cardiac arrests 1.2 in 10,000. 25 cases were studied in great detail, both clinically and physiopathologically. This was thanks to a very full questionnaire most kindly filled up by those who had told us that this type of accident had happened in their practice. The physiopathogenesis of circulatory arrests during laparoscopy is complex. It appears however that among the different potentiating factors are changes in haemodynamics and biological changes that give rise to the greatest risks. Experimental work carried out with a long-tailed baboon was performed by the authors with the idea on the one hand of confirming that haemodynamic and biological troubles resulting from the pneumoperitoneum were important and on the other hand of analysing the changes in detail and of working out prophylactic principles for the anaesthetist and the laparoscopist.
