Randomized Controlled Trial Comparative Study Clinical TrialXenon does not prolong neuromuscular block of rocuronium.
With the exception of xenon, the interaction between muscle relaxants and inhaled anesthetics is known. We therefore compared the pharmacodynamics of rocuronium during xenon anesthesia versus a total IV anesthesia with propofol. Anesthesia was induced with propofol and remifentanil in both the xenon and propofol groups (each n = 20). ⋯ Anesthesia was maintained with xenon and remifentanil (xenon group) or with propofol and remifentanil (propofol group). There were no significant differences between the groups concerning the onset time (xenon group 125 +/- 33 and propofol group 144 +/- 43 s), duration (xenon group 33.2 +/- 10.8 and propofol group 32.6 +/- 8.4 min), recovery index (xenon group 9.4 +/- 6.6 and propofol group 8.4 +/- 5.3 min), and clinical recovery (xenon group 18.0 +/- 10.2 and propofol group 17.1 +/- 8.5 min). We conclude that the neuromuscular blocking effects of rocuronium are not different when given during propofol versus xenon anesthesia.

Randomized Controlled Trial Comparative Study Clinical TrialDeveloping a strategy to improve ventilation in an unprotected airway with a modified mouth-to-bag resuscitator in apneic patients.
The strategies to ensure safety during ventilation of an unprotected airway are limiting airway pressure and/or inspiratory flow. In this prospective, randomized study we assessed the effect of face mask ventilation with small tidal volumes in the modified mouth-to-bag resuscitator (maximal volume, 500 mL) versus a pediatric self-inflatable bag versus automatic pressure-controlled ventilation in 40 adult apneic patients during induction of anesthesia. The mouth-to-bag resuscitator requires the rescuer to blow up a balloon inside the self-inflating bag that subsequently displaces air which then flows into the patient's airway. ⋯ The tidal volumes were similar between groups. No stomach inflation occurred in either group. We conclude that using a modified mouth-to-bag resuscitator or automatic pressure-controlled ventilation with similar small tidal volumes during face mask ventilation resulted in an approximately 25% reduction in peak airway pressure when compared with a standard pediatric self-inflating bag.
