Randomized Controlled Trial Multicenter Study Observational Study
A multicenter study of the analgesic effects of epidural chloroprocaine after lower limb orthopedic surgery.
To investigate the effects and optimal concentration of chloroprocaine for epidural analgesia after lower limb orthopedic surgery. ⋯ Epidural 1.2% chloroprocaine with 0.4μg/mL fentanyl could generate proper analgesic effects with little influence on mobility in patients undergoing lower limb orthopedic surgery. In addition, it could generate a good sense and movement separation, facilitating the early functional training.

To assess the stability of pharmaceutical suxamethonium (succinylcholine) solution for injection by validated stability-indicating chromatographic method in vials stored at room temperature. ⋯ Storage of suxamethonium solution for injection vials at ambient temperature (22°C-26°C) for 17 days demonstrated that at least 95% of original suxamethonium concentration remained stable.

Observational Study
Evaluation of pH on removed tracheal tubes after general anesthesia: a prospective observational study.
Aspiration pneumonia is a complication of tracheal intubation and mechanical ventilation. We hypothesized that tracheal tubes removed after anesthesia that have an acidic pH may reflect latent regurgitation of gastric fluid. ⋯ Acidic pH was found on about 2.5% of removed tracheal tubes. These tubes were used in patients who were in the prone or head-down position during general anesthesia, although they did not exhibit significant aspiration symptom. Anesthesiologists should be aware of the inherent risk of gastric fluid regurgitation when their patients undergo general anesthesia in these positions.

Randomized Controlled Trial Comparative Study
A comparison of King Vision video laryngoscopy and direct laryngoscopy as performed by residents: a randomized controlled trial.
For more than 40 years, direct laryngoscopy (DL) has been used to assure the airway during endotracheal intubation. The King Vision video laryngoscope is one of the latest devices introduced for endotracheal intubation. We hypothesize that, relative to direct laryngoscopy, it improves the intubation success rate with fewer intubation attempts and no difference in intubation time or complications. ⋯ The use of KVVL by residents with less than 1 year of training (considered nonexperts) significantly improves visualization of the glottis in patients without predictors of difficult airway. The incidence of complications was too low to draw conclusions.

Randomized Controlled Trial Comparative Study
Quality of recovery from anesthesia of patients undergoing balanced or total intravenous general anesthesia. Prospective randomized clinical trial.
The aim of the present study was to assess the quality of recovery from anesthesia of patients subjected to otorhinolaryngological (ORL) surgery under balanced or total intravenous general anesthesia by means of Quality of Recovery-40 (QoR-40) questionnaire. ⋯ The quality of recovery from anesthesia assessed based on the patients' perception did not differ between the ones subjected to either inhalation or intravenous general anesthesia for ORL surgery based on QoR-40 questionnaire assessment.
