- ItemApplication of intra-aortic balloon pump in resection and anastomosis of trachea.(2014-09-05) Ahmadi, Zargham Hossein; Rahnemai-Azar, Amir Ali; Shadmehr, Mohammad Behgam; Parsa, Tahereh; Behzadnia, Neda; Aval, Zahra Ansari; Mokri, Bahareh; Gholamhoseini, HamidehThe intra aortic balloon pump IABP is a mechanical device used to assist cardiac circulatory function in patients suffering from cardiogenic shock congestive heart failure refractory angina and complications of myocardial infarction While using IABP in cardiac surgery is well established there are few studies on the utility of IABP support in high risk cardiac patients undergoing non cardiac surgery Major non cardiac surgeries are associated with high rates of cardiac complications in patients with advanced coronary disease Recent case studies have reported favorable outcomes with the use of IABP support in non cardiac surgery in patients with severe cardiac compromise Using IABP may reduce cardiac complications by providing hemodynamic stability Here we present five cases of IABP use in high risk cardiac patients undergoing resection and anastomosis of the trachea IABP was inserted prior to induction of anesthesia in four of the cases while IABP insertion was withheld in one case In the four cases where IABP support was utilized the IABP was removed between 6 48 hours postoperatively with no complications The patient who did not undergo IABP insertion died on the 8th postoperative day due to uncontrollable pulmonary edema and progressive myocardial infarction We also review the literature and discuss the role of IABP use in non cardiac surgery
- ItemEffects of propofol versus isoflurane on liver function after open thoracotomy.(2014-09-17) Dabir, Shideh; Mohammad-Taheri, Zohreh; Parsa, Tahereh; Abbasi-Nazari, Mohammad; Radpay, Badiozaman; Radmand, GolnarAnesthetic agents and type of surgery may contribute to postoperative hepatic injury Inhalational anesthetics have been associated with hepatic dysfunction after surgery however propofol is expected to have a lower potential for postoperative liver injury This prospective double blind randomized clinical study was planned to determine whether postoperative liver function differs after anesthesia with isoflurane and total intravenous anesthesia with propofol in patients undergoing a posterolateral thoracotomy
- ItemHigh-Frequency Jet Ventilation in Nonintubated Patients.(0000-00-00) Abedini, Atefeh; Kiani, Arda; Taghavi, Kimia; Khalili, Ali; Fard, Alireza Jahangiri; Fadaizadeh, Lida; Salimi, Alireza; Parsa, Tahereh; Aarabi, Akram; Farzanegan, Behrooz; Tootkaboni, Mahsa PourabdollahOBJECTIVES High frequency jet ventilation HFJV is a convenient method for providing ventilation during fiberoptic bronchoscopy We describe an incipient approach of high frequency jet ventilation via the working channel of a flexible bronchoscope for nonintubated patients who suffer from hypoxemia during bronchoscopy The aim of this study was to test the efficacy of this incipient approach and determine the possible complications related to it MATERIALS AND METHODS Sixteen patients who had oxygen saturation below 70 that did not resolve with nasal oxygen for 20 s during interventional bronchoscopy were included in the study High frequency jet ventilation was administrated via the working channel of a bronchoscope for 3 min Arterial blood gas circumscriptions were compared before and after jet ventilation RESULTS Oxygen saturation increased to 90 in all patients 30 s after jet ventilation Mean arterial oxygen saturation pressure increased from 54 84 to 111 98 mmHg with jet ventilation p 0 0001 Arterial carbon dioxide tension decreased after jet ventilation The body mass index had no consequential effect on arterial carbon dioxide pressure after jet ventilation in our patients p 0 1 Complications such as pneumothorax and working channel damage were not observed CONCLUSION High frequency jet ventilation via the working channel of the bronchoscope is a novel method that can provide optimal ventilation with minimal complications to nonintubated patients suffering from hypoxemia during bronchoscopy This method also reduces the duration of bronchoscopy procedures
