Randomized Controlled Trial
Optimum dose of neostigmine to reverse shallow neuromuscular blockade with rocuronium and cisatracurium.
We examined the use of neostigmine for reversing shallow (defined as train-of-four ratio of 0.5), cisatracurium- and rocuronium-induced neuromuscular block in 112 patients, by use of 0 μg.kg(-1) , 10 μg.kg(-1) , 20 μg.kg(-1) or 40 μg.kg(-1) dose of neostigmine for reversal. The times from neostigmine administration to train-of-four ratios of 0.7, 0.9 and 1.0 were evaluated. ⋯ The recovery time from a train-of-four ratio of 0.5-1.0 did not differ between cisatracurium and rocuronium, and was significantly shortened by the administration of neostigmine. We conclude that a neostigmine dose of 40 μg.kg(-1) was the most effective at reducing recovery time after neuromuscular blockade.

We retrospectively analysed 30-day mortality and duration of intubation for 8016 children ventilated for three or more days, sedated with midazolam (n = 7716) or propofol (n = 300). We matched the propensity scores of 263 pairs of children. The propensity-matched 30-day mortality (95% CI) was similar: 17/263 (6.5%) with midazolam vs. 24/263 (9.1%) with propofol, p = 0.26. Weaning from mechanical ventilation of children sedated with midazolam was slower than weaning of children sedated with propofol, subhazard ratio (95% CI) 1.43 (1.18-1.73), p < 0.001.

Sukcharanjit S, Tan AS, Loo AV, Chan XL, Wang CY. The effect of a forced-air warming blanket on patients’ end-tidal and transcutaneous carbon dioxide partial pressures during eye surgery under local anaesthesia: a single-blind, randomised controlled trial. ⋯ In the article [1] by Sukcharanjit et al., data in the ‘Systolic blood pressure; mmHg’ row in Table 1 is listed incorrectly. It should be: 158.0 (14.3) in the Forced air warmer column and 160.9 (15.6) in the Heated Overblanket column.
