No significant difference was found in the number of underinflation episodes between continuous control and routine care periods (median (IQR) 0 (0, 5) versus 2 (0, 7), p = 0.733).
No significant difference was found in duration of P cuff and airway pressure recording [median (IQR) 23 (23.323.3 vs 23.5 h (23, 24), p = 0.066], or in mean airway pressure [13.2 (10.7, 15.5) vs 13.1 cmH2O (15.6, 15.6)] between continuous control and routine care periods, respectively.
Diabetes management requires continuous monitoring and routine provider visits and laboratory tests [ 4].
However, in order to adjust for patient-related confounders, such as tracheal size and aspect, airway pressures, and tracheal tube size, continuous control and routine care of Pcuff were performed in the same patient.
We identified clinical prospective clinical trials that compared the continuous control of Pcuff and routine care regarding the incidence of VAP.
The pneumatic device was efficient in controlling Pcuff (med [IQ] 26 [28, 28] vs 22 [28, 28] cmH2O, during continuous control of Pcuff and routine care, respectively; p = 0.017).
In spite of efficient control of Pcuff, no significant difference was found in microaspiration of gastric content between continuous control of Pcuff and routine care.
No significant difference was found in rate of microaspiration of gastric content, mean pepsin level, or percentage of tracheal aspirates positive for pepsin between continuous control of Pcuff and routine care (Table 3).
No significant difference was found in the percentage of patients with Pcuff 20 30 cmH2O, Pcuff <20 cmH2or or Pcuff >30 cmH2O during continuous control of Pcuff and routine care (Table 2).
No significant difference was found in patient characteristics between the two periods of continuous control of Pcuff and routine care, or between patients intubated with tapered-cuffed tracheal tubes, and those intubated with cylindrical-cuffed tracheal tubes (Tables 1, and 2).
