Randomized Controlled Trial
High-frequency chest wall oscillation in prolonged mechanical ventilation patients: a randomized controlled trial.
Patients with prolonged mechanical ventilation (PMV) often retain airway secretions, which may be cleared with the assistance of high-frequency chest wall oscillation (HFCWO). This study aimed to determine the effectiveness, safety and tolerance/comfort of HFCWO after extubation in PMV patients. ⋯ In PMV patients, HFCWO was safe, comfortable and effective in facilitating airway hygiene after removal of endotracheal tubes, but had no positive impact on weaning success.

Randomized Controlled Trial
Comparison of pressure and volume-controlled ventilation in laparoscopic cholecystectomy operations.
Laparoscopic cholecystectomy has many advantages such as shorter hospital stay of patients, minimal postoperative pain, rapid recovery after the operation; however, systemic disadvantages because intra-abdominal pressure, position and general anaesthesia may also appear. In this study, pressure-controlled ventilation (PCV) and volume-controlled ventilation (VCV) modes during laparoscopic cholecystectomy operations were compared in terms of their effects on haemodynamic, respiratory and blood gas parameters. ⋯ In this study, with volume-controlled ventilation anaesthesia in laparoscopic cholecystectomy, higher tidal volume and lower alveolar-arterial oxygen gradient were achieved after pneumoperitoneum. These findings indicated that VCV mode can provide a better alveolar ventilation than PCV mode in laparoscopic cholecystectomy operations.

Randomized Controlled Trial
Sertraline hydrochloride treatment for patients with stable chronic obstructive pulmonary disease complicated with depression: a randomized controlled trial.
There is a lack of randomized controlled trials to assess the effects of pharmacological treatments in patients with stable chronic obstructive pulmonary disease (COPD) complicated with moderate or severe depression. ⋯ Antidepressant treatment can improve the quality of life and exercise capacity of patients with depression, and it can also improve depression scores, but not lung function.
