Randomized Controlled Trial Comparative Study
Comparison of helmet and facial mask during noninvasive ventilation in patients with acute exacerbation of chronic obstructive pulmonary disease: a randomized controlled study.
Noninvasive mechanical ventilation (NIMV) is an approach to prevent complications in acute respiratory failure. In this study we aimed to compare the efficacy of a full face mask and a helmet in chronic obstructive pulmonary disease (COPD). ⋯ Both masks are efficient in improving the patients' outcome in COPD, but the decrease in PaCO2in the helmet group was slower than in the full face mask group.

Randomized Controlled Trial
The McGrath Series 5 video laryngoscope versus the Macintosh laryngoscope: a randomized trial in obstetric patients.
Anesthesiologists have encountered various difficulties in securing the airway. Therefore, we compare the intubation times and hemodynamic changes between the McGrath Series 5 video laryngoscope and the Macintosh laryngoscope. ⋯ The McGrath Series 5 video laryngoscope provides excellent views during orotracheal intubation in obstetric anesthesia with normal airways.

Randomized Controlled Trial
A comparison of the effects of hyperbaric and isobaric bupivacaine spinal anesthesia on hemodynamics and heart rate variability.
To compare the effects of hyperbaric and isobaric bupivacaine spinal anesthesia on hemodynamics and heart rate variability (HRV) in nonobstetric surgery. ⋯ Hyperbaric bupivacaine caused a significantly greater decrease in LF/HF ratios and a significantly greater increase in HF values.
