Randomized Controlled Trial Clinical TrialEffects of landiolol on hemodynamic response and seizure duration during electroconvulsive therapy.
This study was done to evaluate the effect of landiolol, an ultra-short-acting beta-blocker, on the hemodynamic response and the duration of seizure activity during electroconvulsive therapy (ECT). ⋯ As the landiolol dose of 0.2 mg x kg(-1) caused shorter seizure duration, and because the hemodynamic effects after ECT of the 0.1 mg x kg(-1) and 0.2 mg x kg(-1) doses were similar, it was concluded that a 0.1 mg x kg(-1) landiolol bolus was the appropriate dose pretreatment before ECT.

Randomized Controlled TrialBispectral index-guided desflurane and propofol anesthesia in ambulatory arthroscopy: comparison of recovery and discharge profiles.
In this prospective, randomized study we compared the recovery profiles of bispectral index (BIS)-guided anesthesia regimens with desflurane or propofol in ambulatory arthroscopy. Fifty ASA I-II adult patients who underwent knee arthroscopy were randomized to receive desflurane (D) or propofol (P) infusion accompanied by remifentanil and nitrous oxide during maintenance, titrated to maintain a bispectral index value between 50 and 60. Initial awakening, fast-track eligibility, and home readiness as well as intraoperative hemodynamics, were compared. ⋯ However, home readiness did not differ significantly between the groups. Desflurane is an alternative to propofol for BIS-guided ambulatory anesthesia. Using desflurane in combination with opioid analgesics blunted its rapid emergence characteristics, and the higher frequency of emetic symptoms with desflurane diminished the success of its fast-track eligibility.

Randomized Controlled TrialDexmedetomidine during local anesthesia.
The objective of our study was to assess the efficacy and safety of dexmedetomidine given in a small dose for a 1-h infusion as an adjuvant to local analgesia in ophthalmic operations. The study was double-blind prospective, randomized, and placebo controlled. We studied the effects of a small dose of dexmedetomidine (0.5 micro.kg(-1).h(-1) for 10 min followed by 0.2 micro.kg(-1).h(-1) for 50 min. ⋯ Bispectral index values were significantly lower in the dexmedetomidine group than the placebo group. Also, intraocular pressure significantly decreased in the dexmedetomidine group compared to the placebo group. The study revealed that dexmedetomidine in the studied dose has a sedative effect, provides safe control of heart rate and blood pressure, and also decreases intraocular pressure during ophthalmic surgery under local anesthesia.
