The effects of intravenous nicardipine on the neuromuscular blockade produced by single bolus injection of vecuronium were studied in surgical patients undergoing tracheal intubation. We measured the mechanical response of the abductor pollicis muscle to stimulation of the ulnar nerve in a train-of-four sequence at 2 Hz and recorded the amplitudes of the first response (T1). Anesthesia was induced with thiopental 5 mg.kg-1 with or without nicardipine 10 micrograms.kg-1 followed by injection of vecuronium in a dose of either 0.1 or 0.15 mg.kg-1. ⋯ These values were significantly shorter than those observed in patients without nicardipine administration (n = 10, P less than 0.05), and were not significantly different from the values in patients who had received vecuronium 0.15 mg.kg-1 (n = 10). On the other hand, the time for 25% recovery in T1 was uninfluenced by nicardipine. Present study indicates that nicardipine pretreatment possibly shortens the onset time after minor or moderate dose of vecuronium.

The author designed a cart which can safely carry and accommodate Selectatec vaporizers (Ohmeda). The cart consists of ten parking brackets on which Selectatec vaporizers can be mounted and their support arms with castors. An anesthetic machine which has a Selectatec manifold allows easy removal and replacement of vaporizers, but there are several troublesome regulations regarding conveyance and accommodation of vaporizers. By the use of the cart, all these problems were completely solved and the advantage of the centralization of many vaporizers was accomplished.
