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.

Comparative Study Controlled Clinical Trial
Age-dependent relationship between bispectral index and sedation level.
To determine the relationship between bispectral index (BIS) and sedation. ⋯ BIS correlated with sedation depth, with BIS scores in group H than group M at a deep sedation depth.

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
Hemodynamic effects of 6% and 10% hydroxyethyl starch solutions versus 4% albumin solution in septic patients.
To compare the hemodynamic effects of two different concentrations of pentastarch hydroxyethyl starch (HES; 200/0.5) solutions with a 4% human albumin solution for fluid resuscitation. ⋯ HES is as effective as albumin for volume resuscitation in septic patients.

To investigate sevoflurane blood concentrations on loss of consciousness during single-breath induction and ensuing tidal volume ventilation. ⋯ The depth of sevoflurane after 9 minutes of ventilation of 3.5% sevoflurane is not sufficient to suppress intubation-induced hemodynamic response.
