Objectives:To compare the insertion time, ease of device insertion, ease of gastric tube insertion, airway leakage pressure, and complications between the laryngeal mask airway (LMA) ProSeal (P-LMA) and I-gel (I-gel) groups.Methods:Eighty patients with age range 18-65 years who underwent elective surgery were included in the study. The study took place in the operation rooms of Haydarpaşa Numune Hospital, Istanbul, Turkey from November 2013 to April 2014. Patients were equally randomized into 2 groups; the I-gel group, and the P-LMA group. In both groups, the same specialist inserted the supraglottic airway devices. The insertion time of the devices, difficulty during insertion, difficulty during gastric tube insertion, coverage of airway pressure, and complications were recorded.Results:The mean insertion time in the I-gel group was significantly lower than that of the P-LMA group (I-gel: 8±3; P-LMA: 13±5 s). The insertion success rate was higher in the I-gel group (100%, first attempt) than in the P-LMA group (82.5%, first attempt). The gastric tube placement success rate was higher in the I-gel group (92.5%, first attempt) than in the P-LMA group (72.5%, first attempt). The airway leakage pressures were similar.Conclusion:Insertion was easier, insertion time was lower, and nasogastric tube insertion success was higher with the I-gel application, and is, therefore, the preferred LMA.

Objectives:To compare analgesia nociception index (ANI) values, visual analog scale (VAS) values, and hemodynamic parameters in hysteroscopy patients who received remifentanil and dexmedetomidine during general anesthesia.Methods:In total, 30 patients who underwent hysteroscopy between March and September 2016 at the University of Health Sciences Fatih Sultan Mehmet Health Research and Application Center, İstanbul, Turkey were included in this prospective study. Standard hemodynamic monitoring, ANI, and bispectral index (BIS) monitoring were applied to the patients. At 10 min prior to induction, 1 µg/kg of remifentanil was applied in Group R (n=15) and 1 µg/kg of dexmedetomidine was applied in Group D (n=15). After induction, sevoflurane was used for maintenance with dexmedetomidine at 0.2-0.7 µg/kg/hour in Group D and remifentanil at 0.05-0.5 µg/kg/minute in Group R. Perioperative and postoperative analgesia levels (ANI and VAS, respectively), hemodynamics, and complications were recorded.Results:Even though the ANI levels in Group D were lower at the perioperative 5th and 10th minutes, the ANI values were between the targeted limits, except for the measurement after I-gel insertion, in both groups. Hemodynamic parameters were within normal limits, but the mean arterial pressures in Group R after induction, following I-gel placement, and at the perioperative 5th, 10th, and 20th minutes were lower and at postoperative 30th minute were significantly higher.Conclusion:Dexmedetomidine and remifentanil are both efficacious agents for perioperative analgesia in hysteroscopy cases.

OBJECTIVE: Investigating the effects of coenzyme Q10 on organ damage and survival on mice in cecal ligation perforation (CLP) model in sepsis. BACKGROUND: Coenzyme Q10 is an antioxidant molecule playing an important role in mitochondria. Mitochondrial dysfunction is an important mechanism in sepsis pathophysiology. METHODS: Nintyfour Swiss Albino male mice were divided into 8 groups. CLP was performed in Group I. Coenzyme Q10, 100 mg/kg subcutaneously, was given 5 hours after CLP to Group II and 20 hours after CLP to Group III. Sham operation was performed in Group IV, 100 mg/kg coenzyme Q10 subcutaneously was given 5 hours after sham operation to Group V and 20 hours after sham operation to Group VI. No operation was performed in Group VII; coenzyme Q10, 100 mg/kg subcutaneously, was given to Group VIII. Antibiotics and fl uid replacement were applied for 3 days. The mice still living were sacrifi ced at 576th hour. The organ damages were scored under light microscopy. RESULTS: The survival of Group I and Group II was lower than that of the control groups, but the survival in the Group III was similar to control groups. It was established that spleen, kidney, heart damage and total organ damage were decreased when compared to CLP group. CONCLUSIONS: Coenzyme Q10 is effective in decreasing histological organ damage in sepsis (Tab. 3. Fig. 1, Ref. 30).
