Randomized Controlled Trial
Prophylactic phenylephrine infusion for the prevention of hypotension after spinal anesthesia in the elderly: a randomized controlled clinical trial.
Hypotension frequently occurs during spinal anesthesia (SA), especially in the elderly. Phenylephrine is effective to prevent SA-induced hypotension during cesarean delivery. The objective of this study was to evaluate the efficacy and safety of prophylactic infusion of phenylephrine after SA for orthopedic surgery in the elderly. ⋯ Prophylactic phenylephrine infusion is an effective method of reducing SA-induced hypotension in the elderly. Compared with a control group, it delays the time to onset of hypotension and decreases the number of hypotensive episodes per patient. More data are needed to evaluate clinical outcomes of such a strategy.

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
A comparison of 3 ventilation strategies in children younger than 1 year using a Proseal laryngeal mask airway: a randomized controlled trial.
To determine quantitative differences in several routinely measured ventilation parameters using a standardized anesthetic technique and 3 different ventilation modalities in patients younger than 1 year with a ProSeal laryngeal mask airway (PLMA). ⋯ All 3 modes of ventilation using a PLMA were safe in children younger than 1 year. Although we did not observe a statistically significant increase in etco2, differences in TV and RR, and the small but significant incidence of apnea may make PSV or PCV more optimal ventilation strategies in children younger than 1 year when using a PLMA.

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.

Randomized Controlled Trial Multicenter Study Comparative Study
Effect of endovenous lidocaine on analgesia and serum cytokines: double-blinded and randomized trial.
This trial aimed to compare postoperative analgesia, opioid consumption, duration of ileus and hospital stay, and cytokine levels in patients undergoing laparoscopic cholecystectomies who received intravenous lidocaine in comparison with a control group. ⋯ Intravenous lidocaine was not able to reduce postoperative pain, opioid consumption, and duration of ileus or length of hospital stay. However, its anti-inflammatory effect was noticeable.
