Erratum: Upper airway collapsibility during dexmedetomidine and propofol sedation in healthy volunteers: A nonblinded randomized crossover study (Journal of Physical Chemistry (2019) 131 (962-973) DOI: 10.1097/ALN.0000000000002883)

In the November 2019 issue, the article “Upper Airway Collapsibility during Dexmedetomidine and Propofol Sedation in HealthyVolunteers” (Lodenius Å, Maddison KJ, Lawther BK, Scheinin M, Eriksson LI, Eastwood PR, Hillman DR, Fagerlund MJ,Walsh JH: Anesthesiology 2019; 131:962-73. doi: 10.1097/ALN.0000000000002883) contains an error. In the Results section of the Abstract, median (interquartile range) pharyngeal critical pressure “0.3 (−9.2 to 1.4)” should be “−0.3 (−9.2 to 1.4).”The corrected sentence reads: “Median (interquartile range) pharyngeal critical pressure was −2.0 (less than −15 to 2.3) and 0.9 (less than −15 to 1.5) cm H₂O (mean difference, 0.9; 95% CI, −4.7 to 3.1) during low infusion rates (P = 0.595) versus −0.3 (−9.2 to 1.4) and −0.6 (−7.7 to 1.3) cm H₂O (mean difference, 0.0; 95% CI, −2.1 to 2.1; P = 0.980) during moderate infusion of dexmedetomidine and propofol, respectively.”The same error was repeated in the Primary Outcome: Upper Airway Collapsibility, Pharyngeal Critical Pressure, during Sedation with Dexmedetomidine or Propofol section on page 968. The authors regret the error. The online version and PDF of the article have been corrected.
