Randomized Controlled Trial Comparative Study Clinical Trial
Rocuronium versus succinylcholine-atracurium for tracheal intubation and maintenance relaxation during propofol anesthesia.
To compare the onset and offset time (clinical duration), and intubating conditions obtained with rocuronium bromide 0.6 mg/kg and succinylcholine 1.0 mg/kg after induction with propofol and fentanyl; and to compare rocuronium with atracurium for maintenance during propofol anesthesia. ⋯ Rocuronium bromide at a dose of 0.6 mg/kg, when used with propofol and fentanyl for induction, provides intubating conditions similar to succinylcholine 1.0 mg/kg at 1 minute. The actual onset time and offset time, however, are significantly longer with rocuronium. There was no difference between atracurium and rocuronium as a maintenance drug. Rocuronium is suitable for surgical procedures greater than 30 minutes, eliminating the need for an additional relaxant to succinylcholine.

Randomized Controlled Trial Comparative Study Clinical Trial
Effectiveness of remifentanil versus traditional fentanyl-based anesthetic in high-risk outpatient surgery.
To determine if remifentanil would offer a superior hemodynamic and recovery profile compared to the current standard of care, which implements a fentanyl-based technique. ⋯ Remifentanil, a new short-acting opioid, offers excellent hemodynamic control for brief, intense outpatient procedures performed in high-risk patients; however, its use was not associated with any improvement in recovery profiles.

Randomized Controlled Trial Clinical Trial
Postoperative analgesia by intraarticular and epidural neostigmine following knee surgery.
To define the analgesic efficacy, and to identify a possible site of action, of epidural and intraarticular neostigmine. ⋯ Although peripheral neostigmine 1 microg/kg did not result in postoperative analgesia, the same dose applied epidurally resulted in over 5 hours of analgesia, similar to a fivefold dose applied peripherally. The results suggest that epidural neostigmine has a greater analgesic efficacy than peripherally applied neostigmine.

To examine the impact on perioperative care of routine Bispectral Index (BIS) monitoring during general anesthesia throughout an entire operating room (OR) suite. ⋯ Routine application of BIS monitoring throughout an OR suite impacted clinical outcome only if guideline targets were met. BIS values within the last 30 minutes of surgery were not predictive of emergence or recovery. Hypnotic maintenance at BIS < 50 did not confer any clinical advantage over unmonitored cases. Anesthetic maintenance at BIS values between 50 and 65 was associated with shortened emergence and recovery from general anesthesia.

Continuous interscalene brachial plexus blockade can provide anesthesia and analgesia in the shoulder region. Difficulty accessing the interscalene space and premature displacement of interscalene catheters may preclude their use in certain situations. We present two case reports in which a catheter was advanced from the axilla along the brachial plexus sheath to the interscalene space to provide continuous cervicobrachial plexus analgesia. ⋯ In the second case report, a catheter was inserted in a similar fashion from the axillary to the interscalene space to provide 14 days of continuous analgesia in the management of complex regional pain syndrome. We have found that this technique allows us to secure the catheter more easily than with the traditional interscalene approach and thus prevents premature dislodgment. This approach may be a suitable alternative when either an interscalene or an infraclavicular catheter may not be inserted.
