Randomized Controlled Trial
Pressure-controlled ventilation-volume guaranteed mode improves bronchial mucus transport velocity in patients during laparoscopic surgery for gynecological oncology: a randomized controlled study.
Mechanical ventilation during general anesthesia may impair airway mucosal function. This study aimed to investigate the effect of pressure-controlled ventilation-volume guaranteed (PCV-VG) on bronchial mucus transport velocity (BTV) in patients during laparoscopic surgery for gynecological oncology compared with volume controlled ventilation (VCV). ⋯ PCV-VG is more suitable for patients undergoing laparoscopic surgery for gynecological oncology than VCV since it can protect mucociliary clearance function.

Randomized Controlled Trial
The effect of warming ropivacaine on ultrasound-guided subgluteal sciatic nerve block: a randomized controlled trial.
There is a long latent period for the sciatic nerve block before a satisfactory block is attained. Changes in the temperature of local anesthetics may influence the characters of the peripheral nerve block. This study was designed to evaluate the effect of warming ropivacaine on the ultrasound-guided subgluteal sciatic nerve block. ⋯ Warming ropivacaine 0.5% to 30℃ accelerates the onset time of sensory and motor blockade in the ultrasound-guided subgluteal sciatic nerve block and it has no influence on the duration of sensory and motor blockade.

Randomized Controlled Trial Multicenter Study
Effect of dexamethasone and ramosetron on the prevention of postoperative nausea and vomiting in low-risk patients: a randomized, double-blind, placebo-controlled, multicenter trial.
Several studies have investigated the effect of antiemetics on postoperative nausea and vomiting (PONV) in high-risk groups. However, few studies have investigated the effect of antiemetics in patients at low risk of developing PONV. ⋯ The combination of dexamethasone and ramosetron demonstrated a superior effect in preventing PONV for 48 h after surgery under general anesthesia than saline in patients at low risk of developing PONV. Compared with saline injections, ramosetron injections yielded better outcomes for the incidence of PONV and the use of rescue antiemetics and rescue analgesics 0-1 h postoperatively.

Randomized Controlled Trial
Single injection technique with ultrasound-guided superficial cervical fascia block combined with brachial plexus block in clavicular surgery: a prospective randomized comparative trial.
To investigate the effects of a single injection technique with ultrasound-guided superficial cervical fascia block combined with brachial plexus block in clavicular surgery. ⋯ The application of the single injection technique with ultrasound-guided superficial cervical fascia block combined with brachial plexus block in clavicular surgery is beneficial because it shortens the operation time, has a faster onset, produces a more effective block and prolongs the longer analgesia time.

Randomized Controlled Trial
Effects of laryngeal mask ventilation on postoperative atelectasis in children undergoing day surgery: a randomized controlled trial.
To compare the effects of laryngeal mask mechanical ventilation and preserved spontaneous breathing on postoperative atelectasis in children undergoing day surgery. ⋯ Laryngeal mask mechanical ventilation can reduce the incidence and severity of postoperative atelectasis in children undergoing day surgery, and we didn't encounter any complications such as reflux and aspiration in children during the perioperative period, so mechanical ventilation was recommended to be used for airway management.
