Randomized Controlled Trial Comparative Study Clinical TrialIntubating conditions and onset of neuromuscular block of rocuronium (Org 9426); a comparison with suxamethonium.
The intubating conditions and neuromuscular blocking profile following 600 micrograms.kg-1 rocuronium (Org 9426) have been investigated in patients under various experimental conditions. They were compared with conditions following 1.5 mg.kg-1 suxamethonium, preceded by a precurarising dose (10 mg) of gallamine, and with those in a control group in the absence of a muscle relaxant. Rocuronium produced good to excellent intubating conditions at 60 as well as at 90 s after administration, even though there was only a partial blockade of the adductor pollicis muscle. ⋯ The clinical duration and the recovery time of 600 micrograms.kg-1 of rocuronium were 24(4) and 9(3) min (mean(s.d.)), respectively. Rocuronium may have a major advantage over existing non-depolarising muscle relaxants due to the early presence of excellent intubating conditions. The results indicate that rocuronium may replace suxamethonium in procedures in which rapid sequence induction is required.

Randomized Controlled Trial Clinical Trial
Partial attenuation of the cardiovascular responses to tracheal intubation with oral nisoldipine.
To evaluate the efficacy and safety of nisoldipine given orally in attenuating the cardiovascular responses to laryngoscopy and tracheal intubation. ⋯ Oral administration of nisoldipine before induction of anesthesia is a simple, practical, and safe method for attenuating pressor response to laryngoscopy and tracheal intubation.

The study was conducted to evaluate the usefulness of an esophageal detector device (EDD) to correctly differentiate between esophageal and tracheal intubation. The study was conducted in the emergency department using 10 recently decreased cadavers (nine males, one female, age range 50-72 years). An 8-mm internal diameter endotracheal tube was placed orally into the trachea, and a second 8-mm ID tube was placed orally into the esophagus. ⋯ There were a total of 45 trials performed on the cadavers (median, four evaluations/cadaver, range, one-eight). For the tracheal tube, the EDD inflated immediately in all cases; it was thus 100% correct in identification of tracheal intubation. For the esophageal tube, the EDD did not inflate in 44 cases, and in one case it filled with vomitus; it thus correctly identified esophageal intubation in all cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Use of many different types of monitors during resuscitation has been described in the literature. These monitors differ in their usefulness, technical feasibility, initial costs, and long-term costs (Table 4). ⋯ In spite of considerable advances in technology over the past 30 years, survival from CPR has changed little over that time. Although numerous types of monitoring during resuscitation are possible, and sometimes useful, the impact of expensive technology on ultimate outcome (survival) must be critically evaluated.

Comparative StudyEfficacy of the FEF colorimetric end-tidal carbon dioxide detector in children.
Direct laryngoscopy and observation of endotracheal tube (ETT) passage between the vocal cords remain the criterion standard for verifying endotracheal intubation. Detection of end-tidal carbon dioxide (ETCO2) serves as an invaluable adjunct to confirm endotracheal intubation, detect inadvertent esophageal intubation, and monitor for accidental tracheal extubation. Capnography, however, is often unavailable outside the operating suite. ⋯ The associations among color level, infrared ETCO2 determinations, ETT size, and ETT "leak" pressures estimated by Spearman rank correlation analysis were significant only for higher infrared ETCO2 values with higher ETT leak pressures (P less than 0.05). No complications were observed. The Fenem disposable colorimetric ETCO2 detector effectively confirms clinical signs of endotracheal intubation in children when capnography is unavailable.(ABSTRACT TRUNCATED AT 250 WORDS)
