Randomized Controlled Trial Clinical Trial
Antagonism of profound cisatracurium and rocuronium block: the role of objective assessment of neuromuscular function.
The purpose of this study is to determine the incidence of significant (train-of-four [TOF] ratio <0.70), but clinically undetectable (TOF ratio >0.40), residual neuromuscular block after neostigmine antagonism of profound cisatracurium (CIS) or rocuronium (ROC) block. ⋯ Most clinicians cannot detect tactile fade once the TOF ratio exceeds 0.40. When reversing profound block, an objective monitor of neuromuscular function is required if the extent of residual block is to be assessed with any confidence.

Randomized Controlled Trial Comparative Study Clinical Trial
Recovery and cognitive function after fentanyl or remifentanil administration for carotid endarterectomy.
To compare recovery and restoration of cognitive function after fentanyl-propofol or remifentanil-propofol anesthesia administration in patients undergoing carotid endarterectomy. ⋯ Although intraoperative hemodynamics were better preserved and immediate recovery was more rapid with remifentanil, overall postoperative recovery and restoration of cognitive functions as well as postoperative pain intensity seem to be similar for patients receiving remifentanil and for those receiving fentanyl combined with propofol for carotid endarterectomy operations.

Randomized Controlled Trial Clinical Trial
Constant positive airway pressure reduces hypoventilation induced by inhalation anesthesia.
To discover if reducing respiratory system impedance would increase tidal volume and improve ventilation during inhalation anesthesia. ⋯ We conclude that constant positive airway pressure titrated to optimal respiratory system compliance will increase efficiency of inspiratory muscles and improve ventilation. Constant positive airway pressure facilitates a pattern of breathing that minimizes some of the adverse pulmonary effects of inhalation anesthesia.

To compare the effect of inspiratory time and lung compliance on tidal volume (Vt) delivery in anesthesia and intensive care unit (ICU) ventilators operating in pressure control mode. ⋯ Differences in inspiratory flow delivery between ICU and anesthesia ventilators can cause differences in Vt delivery when the pressure control mode is used at high RRs. These differences can significantly impact the perioperative care of critically ill patients requiring ventilatory support.
