Methods: This prospective randomized study was conducted in the emergency department of a tertiary care, university-affiliated medical center. All sedations and orthopaedic manipulations were performed by trained and approved orthopaedic residents assisted by a registered nurse according to the same protocol. Sedation time and adverse events were recorded in real time.

Results: Sixty adults Epigenetic pathway inhibitor (thirty-five men and twenty-five women) with a mean age (and standard deviation) of 45 +/- 17 years were randomly enrolled in the study, with thirty patients being managed with

each regimen. The average recovery time was 7.8 +/- 3.7 minutes following sedation with propofol, compared with 30.7 +/- 10.1 minutes following sedation with midazolam/ketamine (p < 0.001). The average total sedation time was 16.2 +/- 3.8 minutes for the propofol group, compared with 41.6 +/- 10.7 minutes for the midazolam/ketamine group

(p < 0.001). The overall rate of respiratory and hemodynamic adverse events was 20% for the propofol group and 10% for the midazolam/ketamine group.

Conclusions: The use of propofol for an orthopaedic procedure requiring sedation in the emergency find more department expedites patient management and saves time in comparison with the use of midazolam/ketamine.”
“Background: P-wave duration and dispersion (PWD) have been shown to be noninvasive predictors for development of atrial fibrillation. Thus, it may be possible to attenuate atrial

fibrillation risk through normalization of P-wave duration and dispersion. Trimetazidine, a metabolic modulator, CCI-779 has been reported to improve cardiac function in heart failure (HF) patients.

Methods: Thirty-six HF patients being treated with angiotensin inhibitors, carvedilol, spironolactone, and furosemide were prescribed trimetazidine, 20 mg three times a day. Electrocardiographic and echocardiographic examinations were obtained before and 6 months after addition of trimetazidine in HF patients and 36 healthy control group patients having normal echocardiographic examination.

Results: Maximum P-wave duration (Pmax) (106.7 +/- 15.8 vs. 91.7 +/- 12.7 ms) and PWD (57.2 +/- 15.4 vs. 37.9 +/- 16.7 ms) were significantly longer in HF patients compared to the control group. There were significant correlations of Pmax and PWD with left atrial diameter (r = 0.508, P = < 0.001 and r = 0.315, P = 0.029), left ventricular ejection fraction (LVEF) (r = 0.401, p = 0.005 and r = 0.396, P = 0.005), deceleration time (r = 0.296, P = 0.032 and r = 0.312, P = 0.035), and isovolumetric relaxation time (r = 0.265, P = 0.038 and r = 0.322, P = 0.015). There were significant improvements in LVEF (32.7 +/- 6.5% to 37.2 +/- 5.5%, P = 0.036), left atrial diameter (41.5 +/- 6.7 to 40.3 +/- 6.1 mm, P < 0.001), and Pmax (106.7 +/- 15.8 to 102.
