patients and methods in a double-blind clinical trial, 103 patients (american society of anesthesiologists class i, ii) aged 18 - 45 years old, who were septorhinoplasty candidates, were randomly assigned into two groups, a 900 mg gabapentin group and placebo, in amir-al-momenin academic hospital. the drug was prescribed to the patients orally, 2 hours before the operation. anesthetic technique...

background operating room (or) planning involves the creation of a “master surgical schedule” in which surgeons are assigned to specific operating rooms (ors) on specific days of a week. the master schedule is typically one or two weeks long repeatable for several months. objectives the purpose of this study was to recommend using a mathematical program to generate a rotation in a way that the ...

background: there are challenges ahead of short-term hospitalization of low-risk patients hospitalized only for monitoring of severe disease who may die soon after admission. the purpose of this study was to suggest strategies for the management of icu stay lengths and to ensure optimal use of icu resources.   methods: the study was conducted retrospectively on 246 patients admitted to 9 genera...

due to an adenocarcinoma of the right upper lobe with infiltration of the main bronchus a 49-years-old female patient underwent an upper bilobectomy with sleeve resection. after two completed chemotherapy bouts and signs of sepsis another thoracotomy was inevitable.  as a complicating factor a supracarinal, necrotic and perforating lesion of the trachea appeared. the defect can be initially rep...

right ventricular failure due to right coronary artery disease, right ventricular hypertrophy, stunning, abnormal septal motion, myocardial infarction, or non-homogeneous distribution of cardioplegia is an uncommon but serious complication of open heart surgery. we report a patient with severe right ventricular hypertrophy secondary to severe mitral valve stenosis and another patient with detac...

a common complication of prosthetic heart valves is thrombosis. although the incidence of prosthetic valve thrombosis (pvt) in the tricuspid position is high, there are not enough data on the management of it, in contrast to left-sided pvt. here, we describe three cases of tricuspid pvt with three different management approaches: thrombolytic therapy; close observation with oral anticoagulants;...

background: brain type natriuretic peptide (bnp) is a cardiac hormone that is secreted mainly by the ventricles in response to volume expansion and pressure load. it can predict post-operative complications after heart surgery in adults. we sought to investigate the prognostic value of bnp in children after heart surgery. methods: we measured the bnp serum levels in 96 children with congenital ...

background: extubation is associated with the risk of complications such as accumulated secretion above the endotracheal tube cuff, eventual atelectasia following a reduction in pulmonary volumes because of a lack of physiological positive end expiratory pressure, and intra-tracheal suction. in order to reduce these complications, and, based on basic physiological principles, a new practical ex...

background: postoperative cognitive dysfunction (pocd) has been an important complication of cardiac surgery over the years. neurocognitive dysfunction can affect quality of life and lead to social, functional, emotional, and financial problems in the patient’s life. to reduce pocd, we sought to identify the association between cognitive dysfunction and perioperative factors in patients undergo...

background :the present study was conducted to establish the patterns and risk factors of surgical site infections in our institution between 2006 and 2011.   methods: this was a retrospective cross-sectional study. the surgical site infection (ssi) was identified based on the presence of icd-10-cm diagnostic code in hospital discharge records. by using a standardized data collection form predi...
