Journal Article Review
The research article systematically reviewed pertains to extracorporeal membrane
oxygenation bridging, before and after operation, in the patients who undergo pulmonary-
endarterectomy
1
. Pulmonary arterial hypertension is quite incurable, except for the
chronic-thrombolytic variety. One of the treatment modalities is to perform pulmonary-
endarterectomy, which is the procedure of choice for patients suffering from the disease.
However, one of the risks attached to the procedure is the development of acute
decompensated cardiac and respiratory failure before the procedure or after it. Under
such circumstances, ECMO (extra-corporeal membrane-oxygenation) has a well-
established role as a bridging intervention in cases of development of such a failure. The
purpose of the research
1
was to perform ECMO before endarterectomy to determine its
feasibility in stabilizing the patients.
The research was quantitative in nature and had a retrospective analytic design.
The eligibility criteria for inclusion into the study were explicitly stated and a total of one
hundred and sixty-one subjects were included. The researchers used various outcome-
measures including survival, morbidities, improved hemodynamics to make a comparison
amongst those who survived, and those who did not after the intervention was
undertaken.

Additionally, the researchers made use of data analysis techniques to make a
comparison amongst the patients based on their survival & risk-factors in case of patients
who were intervened, and those who were not.
The results of the study demonstrated that in subjects undertaking ECMO
bridging before and after their surgery, (pulmonary) endarterectomy had good feasibility,
and led to enhanced patient outcomes concerning survival rates. The results demonstrated
one risk factor to have statistical significance (p < 0.05) being use of ECMO in subjects
with vascular resistance in lungs greater than one thousand dynes cm/s

.
The researchers used sound research and statistical procedures to collect, analyze
and interpret data related to their proposed research problem, and provided a thorough
and sound presentation of their results. The significance of the study is that it provides
empirical evidence for an evidence-based practice in relation to a medical practice.
The researchers also presented a thorough discussion of their results, including
references to the findings of prior research like that by Mydin M, Berman M, Klein A et
al. and compared them with the results of their research to arrive at valid conclusions.
