Randomized Controlled Trial Comparative Study Clinical Trial
Laryngeal mask insertion using thiopental and low dose atracurium: a comparison with propofol.
To compare the laryngeal mask airway (LMA) insertion conditions produced by propofol and a thiopental - low dose atracurium combination. ⋯ The combination of fentanyl-thiopental with low dose atracurium (0.05 or 0.1 mg x kg(-1)) provided conditions comparable with those of propofol for LMA insertion.

To compare recovery parameters of total intravenous anesthesia (TIVA) with remifentanil and propofol, hemodynamic responses to perioperative events, and pharmacodynamic parameters of cisatracurium in 22 end-stage renal failure and 22 normal renal function patients. ⋯ End-stage renal failure does not prolong recovery from TIVA with remifentanil and propofol, or the recovery from cisatracurium neuromuscular block.

The auditory evoked potential (AEP) has been proposed as a method to determine depth of anesthesia, as AEPs are generated in the thalamus and cerebral cortex. Because general anesthesia, in part, relies on anesthetic action in the spinal cord, we hypothesized that isoflurane would have indirect depressant effects on the AEP because of its action in the spinal cord. ⋯ Isoflurane action in the spinal cord indirectly alters the AEP, however, the effect is small. These data suggest that isoflurane can depress the transmission of afferent information from the spinal cord to thalamus, midbrain and cerebral cortex.

Randomized Controlled Trial Clinical Trial
Intra-articular tenoxicam improves postoperative analgesia in knee arthroscopy.
Non Steroidal Anti-inflammatory drugs have a well documented benefit in the relief of postoperative pain. This study was designed to compare the analgesic effect of intra-articular tenoxicam 20 mg with intravenous tenoxicam on postoperative pain in 88 patients undergoing day case knee arthroscopy. ⋯ Intra-articular tenoxicam provides superior postoperative analgesia and reduces postoperative analgesic requirements compared with i.v. tenoxicam in patients undergoing day case knee arthroscopy.
