Aim: Evaluation of anesthesiologic parameters, outcomesand complications amongst patients who underwent thoracic aortaprosthesis operations.Methods: Retrospectively 47 patients surgery protocols fromLithuanian Health Sciences University, department of cardiosurgery– intensive therapy. Relevant data was analyzed: age, premedicationselection, hemodinamic parameters, perfusion duration, frequencyof re-oparations, outcomes.Results: Mean age of males 60,8 ± were reviewed 13,87, meanage of females 70,1 ± 8,08 (p=0.052). Females statistically significantlylonger went in hospital p=0.017. Age mean by ANOVAsignificantly differed in survived and non-survived patients groups(p=0.05). Brain perfusion does not influence outcomes significantlyp=0.4. Longer artificial blood stream duration time statisticallysignificantly correlates with mortality p<0.05. Most frequently usedmedicine for premedication was: benzodiazepines 59, 6% (n=28),opioids 53.2% (n=25), betablockers 23.4% (n=11), nitrates 4.3%(n=2). Arterial hypertension, ischemic heart diseases are the mostfrequent side diseases for patients who underwent thoracic aortaprosthesis surgery. Cardiac output did not have significant influencefor outcomes. Grade of aorta valve insufficiency positivelycorrelates with number of complications. The mortality did notdiffer according to localization of aorta aneurysm. Longer cardiacarrest time and longer artificial blood stream time are related tobigger frequency of re-operations p=0.02. ASA functional classespositively correlates with number of complications p=0.04, andASA functional classes also correlates with longer artificial bloodstream time p=0.02. The difference of mortality between extra andplanned operations was not determined p>0.05. The relation betweenoperations on different sites of aorta( ascending aorta, arcus ofaorta, descending aorta) and mortality was not determined p>0.05.Conlcusions: Longer artificial blood stream time is related tofrequency of complications. Most used medication for premedicationwas benzodiazepines, opioids, betablockers, nitrates. Brainperfusion does not influence outcomes. Cardiac output does not influenceoutcomes of surgical treatment. Aortic valve insufficiencycan be related to higher frequency of complications. Mortality didnot depend on localization of thoracic aorta aneurysm.
