Threshing grain of mechanism from chaffy myth of air embolism in laparoscopy - lux et veritas

Shiv Kumar, Om P. Sudrania


Biomechanical processes involving exact mechanism of air embolism (AE) or gas embolism (GE) in pneumoperitoneum (PP) in operative laparoscopy (OL) causing morbidity and mortality lie in air lock (AL) or gas lock (GL) in right side of heart resulting in traffic jam (TJ) for blood flow in pulmonary tree (PT). This also leads to poorly understood cascade of immunopathological pulmonary reactions. These issues are critically reviewed and discussed to thresh the grain of mechanism from husk of myth of ghost of AE or GE in OL for its dreaded moribund complications. Physics of gas is defined with analysis that venous GE is not exclusive to ambient air (AA) in OL but occurs with CO2, N2O, O2 and other gases also. It is important since use of AA in OL is useful or ostensibly better than CO2 in situations like pregnancy, camps, cardiopulmonary cripples, cirrhotics, war fields, etc and economic needing no cylinders as AA is ubiquitous. Even when gas used was or is CO2 or O2 but blemish is labelled on air for embolism imprudently needing scientific scrutiny.
