Randomized Controlled Trial Comparative Study Clinical Trial
Effect of laryngeal mask airway on esophageal motility during general anesthesia.
To determine whether the Laryngeal Mask Airway (LMA) triggers the pharyngo-esophago-gastric reflex during general anesthesia by comparing the esophageal motility of patients with the LMA and endotracheal tube (ETT) in place. ⋯ During the general anesthetic period before the arousal phase in this study, a LMA does not provoke significantly different esophageal peristalsis compared with an ETT. Thus, the LMA is unlikely to stimulate the pharyngo-esophago-gastric reflex during that period.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A comparison of the remifentanil and fentanyl adverse effect profile in a multicenter phase IV study.
To compare the frequency of adverse effects of remifentanil and fentanyl in a large and diverse patient population. ⋯ In the doses used, both remifentanil and fentanyl have a similar frequency of adverse effects except for the higher frequency of hypotension associated with the use of remifentanil.

Several potential complications may occur during identification of the epidural space. We present a case of subarachnoid pneumocephalus as a rare complication of epidural catheter placement.

Randomized Controlled Trial Clinical Trial
Effect of maintenance bolus on the recovery profile of a short-acting nondepolarizing muscle relaxant.
To evaluate the effect of different maintenance boluses of a short-acting nondepolarizing neuromuscular blocking drug on its spontaneous recovery profile during anesthesia. ⋯ Spontaneous recovery of the T(1) to 25% of the baseline value occurred 6 to 10 minutes after a maintenance bolus dose of rapacuronium 0.25 to 0.75 mg x kg(-1) i.v. However, recovery to a TOF>0.7 required 44 to 66 minutes during desflurane anesthesia.
