ABSTRACT
The LMA CTrach system is a new device for airway management and endotracheal intubation under direct vision in both anticipated and unexpected difficult intubation situations. We used this system in 100 patients undergoing general anesthesia for different types of elective surgeries. After randomly selecting the patients for intubation with this new device, the airway characteristics, height, weight, dental overbite and thyromental distance were all evaluated before induction. Our goal was to explore primarily the success rate of intubation with LMA CTrach. We were able to insert LMA CTrach and provide optimal ventilation in all 100 patients. Nonetheless, successful tracheal intubation was performed in 95 patients. Among our patients, 2 had Mallampati grade IV airways with short necks, body mass index [BMI] > 30, and without the capability to bite their upper lips. Amazingly both patients were intubated with this method, proving a device as an assuring approach in cases of difficulty with ventilation and intubation. Of all patients, 44 were females and 56 males. The mean age was 34 +/- 2 years. BMI measured for all patients was 20-25 except for two cases who had BMI > 30. Since the LMA CTrach provided us with direct view of the larynx and vocal cords during intubation even in difficult cases, it can be assumed that this device is a precious aid as equal as fiberoptic bronchoscopy for the anesthesiologists
ABSTRACT
Cirrhosis is terminal stage of many chronic liver diseases like hepatitis C and hepatitis B. In some studies the role of helicobacter pylori has been demonstrated in progress of cirrhosis and its complications, but none of the previous studies has investigated the role of socioeconomic conditions of patients in childhood period in this issue. In a case-control study, we examined 100 cirrhotic patients due to hepatitis [49 hepatitis B and 51 hepatitis C patients] and 101 socioeconomically matched healthy controls presenting to Taleghani Hospital for IgG antibody to helicobacter pylori. IgG antibody to helicobacter pylori was present in 73% of cirrhotic patients and 52% of control group [P < 0.003]. Odds ratio for the presence of IgG antibody to helicobacter pylori in cirrhotic men comparing with healthy men was 3.2 [95%CI: 1.4-7.4]. The relative frequency of IgG antibody to helicobacter pylori found to be higher in cirrhotic patients than in controls with regard to socioeconomic condition in childhood
