Objective. The aim of this study was to determine the types, incidence, and risk factors for early postoperative pulmonary complications in heart transplant recipients. Methods. We retrospectively collected data from the records of consecutive heart transplantations from January 2003 to December 2013. A total of 83 patients underwent heart transplantation. The data collected for each case were demographic features, duration of mechanical ventilation, respiratory problems that developed during the intensive care unit (ICU) stay, and early postoperative mortality (<30 d). Results. Of the 72 patients considered, 52 (72.2%) were male. The overall mean age at the time of transplantation was 32.1 +/- 16.6 years. Twenty-five patients (34.7%) developed early postoperative respiratory complications. The most frequent problem was pleural effusion (n = 19; 26.4%), followed by atelectasis (n = 6; 8.3%), acute respiratory distress syndrome (n = 5; 6.9%), pulmonary edema (n = 4; 5.6%), and pneumonia (n = 3; 4.2%). Postoperative duration of mechanical ventilation (44.2 +/- 59.2 h vs 123.8 +/- 190.8 h; P = .005) and the length of postoperative ICU stay (10.1 +/- 5.8 h vs 19.8 +/- 28.9 h; P = .03) were longer among patients who had respiratory problems. Postoperative length of stay in the hospital (22.3 +/- 12.5 d vs 30.3 +/- 38.3 d; P = .75) was similar in the 2 groups. The overall mortality rate was 12.5% (n = 9). The patients who had respiratory problems did not show higher mortality than those who did not have respiratory problems (16.0% vs 10.6%; P = .71). Conclusions. Respiratory complications were relatively common in our cohort of heart transplant recipients. However, these complications were mostly self-limiting and did not result in worse mortality.

The Evaluation of Hemodynamic Changes During the Reperfusion Phase in Adult Living Donor Liver Transplantations: The Role of Cardiovascular Problems
(2015) Ayhan, A.; Araz, C.; Komurcu, O.; Kaplan, S.; Torgay, A.; Haberal, M.; 0000-0003-3299-6706; 0000-0002-4927-6660; 0000-0002-6829-3300; 0000-0002-3462-7632; 0000-0001-6762-895X; 26036553; AAJ-2057-2021; AAJ-2066-2021; AAJ-4576-2021; AAJ-5221-2021; AAJ-8097-2021; GLV-1652-2022
Objective. This study sought to evaluate the hemodynamic changes of and to analyze the effects of coronary artery disease (CAD) as well as its risk factors on hemodynamic parameters during the reperfusion phase (RP) in adult living donor liver transplantation (ALDLT). Patients and Methods. This single-center retrospective study evaluated 154 adult patients being assessed from January 2001 to December 2013 for orthotopic liver transplantation (OLT). The patients were divided into separate groups according to the presence or absence of CAD and its risk factors, including diabetes, hypertension, dyslipidemia, smoking, sex, and age. The hemodynamic parameters were noted during the RP with respect to the patient files. The comparison of the groups and the effects of cardiovascular problems on hemodynamic parameters were statistically analyzed. Results. A decrease of more than 20% in systolic arterial pressure was seen in 16 (16.7%), 7 (43.8%), and 17 (40.5%) patients without CAD, with CAD, and with its high risk factors (>2), respectively (P < .05). Moreover, diastolic hypotension was seen in 59 (38.3%) patients during RP; of those, 10 (62.5%) had CAD and 19 (45.2%) had CAD high-risk factors. The decline in both systolic and diastolic arterial pressure was significantly correlated with the increased number of risk factors (P < .05). Conclusions. RP in ALDLT remains an issue not only for the surgeons but also for the anesthesiologists. Clinicians should be aware of CAD and its risk factors before OLT and successful management of such problems are mandatory for hemodynamic stability during this formidable process.
