  The aim of this research is to introduce a novel mask which can provide efficient protection against the toxic N2O gas and 131Iodine encountered in the operating room and nuclear medicine hotlabs. The mask is designed in four layers to trap the toxic gases and prevent the inhalation of toxic agents. The preliminary data indicate a 75% protection against 131Iodine evaporates and a 70% protection against N2O gas. This mask shows promising results and can be used as a protective measurement for the health care providers in the developing countries.

  Although difficult endotracheal intubation is associated with increased morbidity and mortality, no consensus exists on the risk factors associated with this complication. Therefore, the aim of our study was to determine the prevalence and risk factors of difficult intubation in a large group of obese patients who had undergonelaparascopicsleeve gastrectomy. We retrospectively evaluated the records of 402 obese patients with body mass index > 35 m2 who had undergone the procedure. The variables of age, sex, thyromental distance (cm), jaw motion, history of sleep apnea, previous history of difficult intubation, difficult intubation during the bariatric surgery and modified Mallampathi grade were analyzed in each patient. The Mallampati grade 3and 4 and history of previous difficult intubation were the only statistically significant variables associated with difficult intubation. Based on the results of our study, these risk factors should be highly considered in the perioperative evaluations of the obese patients.

  Perioperative renal failure is one of the major complications following coronary artery surgeries, leading to increased morbidity and mortality rates in patients; necessitating renal replacement therapy and longer hospital and ICU stay. Considering the antioxidative effects of N-Acetyl Cysteine (NAC) and vitamin C in decreasing inflammatory factors, this study was designed to evaluate and compare the protective effects of these two agents on renal function of high-risk patients undergoing coronary artery surgeries. This study was a randomized clinical trial research. Ninety patients undergoing cardiac bypass surgery, who were considered as high-risk for postoperative renal failure, were randomized into 3 groups. Group A received NAC, group B received NAC plus vitamin C and group C received Dextrose water 5% as placebo. The agents were administered during and 12 and 24 h after the operation. Serum creatinine levels one day before the operation and also on 1st, 2nd and 3rd days after the operation were recorded and compared. The results revealed no significant differences in serum creatinine levels between the three groups in any of the evaluated days. Based on the results of our study, administration of NAC or its combination with vitamin C does not affect the outcome of renal function in high-risk patients undergoing cardiac bypass surgery.
