According to Kanchi (2011), the pulmonary artery catheter is one of the most important and popular advances in the field of cardiac anaesthesia and intensive care; it measures the systolic, diastolic, mean pulmonary artery and the pulmonary capillary occlusion pressures and provides a means to derive many hemodynamic and oxygenation variables. Conversely, Jacka et al (2002) emphasized that the pulmonary artery catheter has the ability to acquire a large amount of physiologic data that aids in reducing uncertainty, facilitate diagnosis and in some cases, to direct interventions. The aforementioned articles were chosen in particular for the reason that, it both facilitated a profound analysis regarding the use of the pulmonary artery catheter in cardiac surgeries.
Literature Review and Critique
The article entitled, Do we need a Pulmonary Artery Catheter in Cardiac Anesthesia?-An Indian Perspective (Kanchi 2011) explored several important reasons why a pulmonary artery catheter is necessary during cardiac surgeries. Pulmonary artery catheterization or Swan-Ganz catheterization is an important technique for monitoring perioperative and postoperative cardiac pressures during open heart surgery (Kaplan et al 2000). This article clearly cited several reasons deemed important by the author why a pulmonary artery catheter should be utilized during cardiac surgeries....
Secondly, there is a lack of correlation between central venous pressure and left-sided filling pressures in patients with moderate-to-severe cardio-pulmonary diseases; hence, it is rather common to observe a significant change in pulmonary capillary wedge pressure or PCWP with no reflection in central venous pressure or CVP (Kanchi 2011). Thirdly, Kanchi (2011) added that a pulmonary artery catheter offers access to obtain various hemodynamic and oxygen delivery parameters, which are of vital importance in a high-risk cardiac surgical patient. Lastly, the control of perioperative hemodynamic profile with the use of cardiovascular drugs, which affect the myocardial contractility and induce pulmonary and systemic vasodilatation/constriction, mandate the use of a PAC for comprehensive management (Kanchi 2011). As stressed also by Chatterjee (2009), individuals in the medical field have learned a great deal with hemodynamics especially in critically ill patients by employing the use of balloon flotation catheters; thus, its importance should not be neglected or overlooked. Furthermore, Stover et al (2009) highlighted that non-invasive cardiac output and blood pressure monitoring and less invasive devices for Goal-Directed Therapy or GDT cited by Della Rocca and Pompei (2011) in their article, cannot replace invasive monitoring system such as pulmonary artery catheters in examining critically ill patients, for the reason that it is clearly less reliable than the invasive methods. The research article by Kanchi (2011) evidently aims to provide comprehensive guidelines and to clearly identify the possible indications of utilizing a pulmonary artery catheter; hence, this research conducted a
