Ultra fast-track extubation in heart transplant surgery patients.

Int J Crit Illn Inj Sci 2015 Apr-Jun;5(2):89-92

Chronic Respiratory Disease Research Center, National Research Institute of Tuberculosis and Lung Disease, Tehran, Iran.

Background: Heart transplant surgeries using cardiopulmonary bypass (CPB) typically requires mechanical ventilation in intensive care units (ICU) in post-operation period. Ultra fast-track extubation (UFE) have been described in patients undergoing various cardiac surgeries.

Aim: To determine the possibility of ultra-fast-track extubation instead of late extubation in post heart transplant patients.

Materials And Methods: Patients randomly assigned into two groups; Ultra fast-track extubation (UFE) group was defined by extubation inside operating room right after surgery. Late extubation group was defined by patients who were not extubated in operating room and transferred to post operation cardiac care unit (CCU) to extubate.

Results: The mean cardiopulmonary bypass time was 136.8 ± 25.7 minutes in ultra-fast extubation and 145.3 ± 29.8 minutes in late extubation patients (P > 0.05). Mechanical ventilation duration (days) was 0 days in ultra-fast and 2.31 ± 1.8 days in late extubation. Length of ICU stay was significantly higher in late extubation group (4.2 ± 1.2 days) than the UFE group (1.72 ± 1.5 days) (P = 0.02). In survival analysis there was no significant difference between ultra-fast and late extubation groups (Log-rank test, P = 0.9).

Conclusions: Patients undergoing cardiac transplant could be managed with "ultra-fast-track extubation", without increased morbidity and mortality.

Massive hemoptysis, a presentation of invasion of aneurysm of descending aorta to bronchopulmonary tree.

Arch Iran Med 2014 Nov;17(11):786-8

Telemedicine Research Center, National Research Institute of Tuberculosis and Lung Diseases (NRITLD), Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Aortobronchial (AB) fistula is a rare disease, which is presented with massive hemoptysis; lethal if not treated. It should be suspected in any patient who presents with massive hemoptysis and had previous thoracic aortic surgery, but even it may be seen in patients without any history of operation on the thoracic aorta. Although, today in many centers endovascular therapy is done for these patients, but it is not the standard approach. Surgery in urgent situations has an essential role in saving the patients. Operative management consists of double lumen intubation and one lung ventilation, followed by femoral artery and vein cannulation, posterolateral thoracotomy and achieving proximal and distal control on the aorta, applying cardiopulmonary bypass (CPB), separation the lesion, and bypass the segment of the diseased aorta by a synthetic graft.

Superior vena cava obstruction after heart transplantation.

Asian Cardiovasc Thorac Ann 2016 Jan 14;24(1):88-90. Epub 2014 Apr 14.

Lung Transplantation Research Center, National Research of Tuberculosis and Lung Diseases, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Superior vena cava obstruction can be a serious complication after heart transplantation. A 58-year-old man with ischemic cardiomyopathy underwent orthotopic bicaval heart transplantation. On the 12th postoperative day, one hour after removing the central venous line, he developed sudden onset of facial edema, cyanosis, and tachycardia. Emergency transesophageal echocardiography revealed superior vena caval thrombosis at the site of anastomosis. Considering the risks of surgical reexploration, the superior vena cava was recanalized by stent deployment. All of the patient's symptoms were relieved a few hours after stent placement.

Anesthesia with etomidate and remifentanil for cesarean section in a patient with severe peripartum cardiomyopathy--a case report.

Middle East J Anaesthesiol 2008 Jun;19(5):1141-9

Department of Cardiovascular Anesthesia, Cardiovascular Research Center, Madani Heart Hospital, Tabriz University of Medical Sciences, Tabriz, Iran.

Patients with peripartum cardiomyopathy may require analgesia/anesthesia for delivery or cesarean section. Many different methods of anesthesia has been used for this purpose. Remifentanil was used safely in peripartum cardiomyopathic patients, but there is not any report about etomidate usage in such patients. We report on a 19 years old patient, at 32 weeks of gestation, with severe peripartum cardiomyopathy, in uncompensated heart failure and pulmonary edema. She was scheduled for emergency cesarean section becaue of threatening mother's life and fetal distress. General anesthesia was induced with etomidate and maintained with remifentanil infusion safely, without any adverse outcome on mother or newborn.
