ABSTRACT
OBJECTIVES: To compare the sedative effects of dexmedetomidine alfentanil versus ketamine-alfentanil in patients undergoing closed reduction of nasal fractures on the basis of intraoperative hemodynamic changes, satisfaction of patients and surgeons, and the adverse effects. METHODS: Sixty patients with ASA class 1 or 2 were randomized to either of two groups, a dexmedetomidine alfentanil group (DA group; n = 30) or a ketamine-alfentanil group (KA group; n = 30). Hemodynamic parameters, oxygenation status, adverse events, the satisfaction of patients and surgeons, and postoperative pain scores by visual analog scale (VAS) were recorded at specific time intervals during the trial. RESULTS: Systolic blood pressure was significantly lower in the DA group than in the KA group from T1 min to T15 min. The duration of the recovery ward stay was longer in the DA group; however, two groups were similar in terms of total anesthesia time and awakening time. Likewise, two groups were similar in terms of the patient and surgeon's satisfaction, pain scores, and the occurrence of adverse effects. CONCLUSIONS: Both sedation methods were safely performed, and dexmedetomidine-alfentanil is as effective as ketamine-alfentanil in patients undergoing short-term operations such as nasal fracture corrections.
ABSTRACT
Despite many advances in the treatment of breast cancer, it is still the second most common cause of death in women in the United States. It has been shown that inflammation plays a major role in the treatment of these cancers and inflammatory factors enhance tumor growth, invasion, metastasis, and vascularization. In this study, we would like to analyze peripheral blood neutrophil-lymphocyte ratio (NLR) in breast cancer patients and its correlation with disease staging. This cross-sectional analytic study was conducted in Imam Hospital, affiliated with Tehran University of Medical Sciences; a total of 195 female patients with breast cancer met the inclusion criteria. All of the patients had a complete blood count with leukocyte differential performed before chemotherapy. Medical records including pathology reports were also available. Data for all patients were collected prior to any surgical intervention. Exclusion criteria included clinical evidence of active infection, presence of hematological disorders, acute as well as chronic inflammatory or autoimmune diseases, or prior steroid therapy. Higher platelet count was significantly associated with the higher stage. The stage was not associated with the hemoglobin level. There was no association between the tumor size and age of patients with NLR. There was a significant relationship between NLR and IDC. There was a significant relationship between IDC and NLRs of less than 8.1 and greater than 3.3. There was a significant relationship between NLR and vascular invasion. There was no association between NLR and estrogen receptor and HER2. There was no significant relationship between the PLR and the cancer stage. In this study, NLR showed a significant relation with the disease staging. As the NLR increases the stage increases as well. Therefore, this ratio may be helpful in the preoperative evaluation of patients with breast cancer.
