Introduction: This study looks at the effect of supplementary intravenous magnesium sulfate on acute pain when administered in patients undergoing lower limb orthopedic surgery using spinal anesthesia with bupivacaine. Method and materials: In this double-blind, randomized, placebo-controlled clinical trial, 60 patients were selected and randomly divided into two groups. Efforts were made to place both groups under the same method of anesthesia. One group received 8 mg/kg intravenous magnesium sulfate, started before the incision and continued up to the end of the surgical procedure, using a 50 ml syringe, via a peripheral large bore catheter; the second group received the same volume of placebos using the same method. To present the results, mean ( AE SD) was used; a P value of o0.05 was considered significant. Results: There was no difference between the two groups in terms of the basic variables. Pain reported by the first

Administration of MgSO4 in elective CABG with CPB can decrease the postoperative NT Pro-BNP levels; also, it decreases their time of postoperative mechanical ventilation.

Repeated implantation failure (RIF) is a worldwide health problem that imposes a great deal of cost on patients and health care system. Vitamin D(3) has been proposed to have positive impact on the process of implantation. The present study was performed to compare the effect of 1,25-dihydroxy vitamin D(3) (1,25(OH)(2)D(3)) on cytokine production by endometrial cells of women with RIF and healthy fertile controls. Whole endometrial cells (WECs) and endometrial stromal cells (ESCs) from RIF and normal fertile women were treated with 1,25(OH)(2)D(3). The levels of IL-10, TGF-β, IFNγ, Il-6, IL-8 and IL-17 in culture supernatants were assayed by ELISA. Also, ability of the cells from both groups to produce 1,25(OH)(2)D(3) was evaluated and compared. 1,25(OH)(2)D(3) down-regulated cytokine production in WECs from both groups except for IL-8 which was upraised. Similar trends were also observed in ESCs except up-regulation of TGF-β in RIF group. Endometrial cells of both groups had comparable capacity to produce 1,25(OH)(2)D(3). Based on the minimal differential immunoregulatory effect of vitamin D(3) on endometrial cells from RIF and control women, it may be suggested that circulating levels of maternal vitamin D(3) be the subject of further investigation.

Background:Cardiovascular problems are among the most common health issues. A considerable number of cardiac patients undergo cardiac surgery, and coronary artery disease patients constitute about two-thirds of all these surgeries. The application of cardiopulmonary bypass (CBP) usually results in some untoward effects.Objectives:Studies have suggested magnesium sulfate (MgSO4) as an anti-inflammatory agent in a coronary artery bypass graft (CABG). This study aimed to assess the effect of an IV MgSO4 infusion during elective CABG (with CBP) on the blood levels of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α).Materials and Methods:During a 12 month period, after review board approval and based on inclusion and exclusion criteria, 90 patients were selected and entered randomly into one of the two study groups (MgSO4 or placebo). Anesthesia, surgery and CBP were performed in exactly the same way, except for the use of MgSO4 or a placebo. Both preoperative and postoperative plasma levels of IL-6 and TNF-α were checked and compared between the two groups using an ELISA.Results:There was no difference found between the two groups with regard to; gender, basic variables, Ejection Fraction (EF), CBP time and aortic cross-clamp time. The preoperative levels of IL-6 and TNF-α were not different; however, their postoperative levels were significantly higher in the placebo group (P value = 0.01 for IL-6 and 0.005 for TNF-α).Conclusions:This study showed that MgSO4 infusion could suppress part of the inflammatory response after CABG with CBP. This was demonstrated by decreased levels of interleukin-6 and TNF-α in postoperative serum levels in elective CABG with CBP.

Nowadays, coronary artery bypass grafting (CABG) is considered to be one of the most common surgical procedures. This procedure has been the main topic in many clinical research studies, which have assessed the effect of the procedure on patients’ outcomes. Like other surgical procedures, this procedure is also accompanied by a number of unwanted complications, including those of the respiratory system. Since the respiratory system plays an integral role in defining the clinical outcome of patients, improvements in studies that can assess and predict clinical outcomes of the respiratory system, assume greater importance. There are a number of predictive models which can assess patients in the preoperative period and introduce a number of risk factors, which could be considered as prognostic factors for patients undergoing CABG. The respiratory system is among the clinical systems that are assessed in many prediction scoring systems. This review assesses the main studies which have evaluated the possible risk factors for postoperative respiratory mortality and morbidity, in patients undergoing CABG.
