Randomized Controlled Trial Comparative Study
A clinical evaluation of four disposable laryngeal masks in adult patients.
To compare the clinical use of four disposable laryngeal masks (DLMs): the Ambu laryngeal mask [Ambu LM], Solus, Laryngeal Mask Airway (LMA) Unique, and Soft Seal. ⋯ The Ambu LM and LMA Unique DLMs appear to be easier to insert by inexperienced residents and are less traumatic for the patient. The Soft Seal achieves a higher airway seal than other devices, but it causes more mucosal trauma. The Solus had the highest insertion failure rate of the 4 groups.

Randomized Controlled Trial Comparative Study
A randomized, double-blind, prospective study comparing the efficacy of continuous versus pulsed radiofrequency in the treatment of lumbar facet syndrome.
To compare the efficacy of continuous radiofrequency (CRF) thermocoagulation with pulsed radiofrequency (PRF) in the treatment of lumbar facet syndrome. ⋯ Although there was no significant difference between CRF and PRF therapy in long-term outcome in the treatment of lumbar facet syndrome, there was a greater improvement over time noted within the CRF group.

Randomized Controlled Trial Comparative Study
Gastroesophageal regurgitation during anesthesia and controlled ventilation with six airway devices.
To investigate the frequency of gastroesophageal regurgitation and respiratory mechanics during positive pressure ventilation using 5 supraglottic devices or an endotracheal tube (ETT). ⋯ The frequency of gastroesophageal regurgitation in anesthetized, unparalyzed, mechanically ventilated patients was similar in patients whose lungs were ventilated with either the Cobra Perilaryngeal Airway, LMA Classic, Fastrach, ProSeal, laryngeal tube, or ETT.

Randomized Controlled Trial Comparative Study
Single-injection femoral nerve block with 0.25% ropivacaine or 0.25% bupivacaine for postoperative analgesia after total knee replacement or anterior cruciate ligament reconstruction.
To investigate the effects of single-injection femoral nerve block (FNB) in postoperative pain after total knee replacement (TKR) and anterior cruciate ligament (ACL) reconstruction. ⋯ Femoral nerve block using 0.25% ropivacaine or 0.25% bupivacaine is an effective method of postoperative analgesia after TKR and ACL reconstruction, particularly for the first 10 hours after spinal anesthesia.
