AI Article Synopsis
- * The initial cuff pressure was set at 26 cmHO, with fluctuations observed; pressures exceeded 30 cmHO in all patients and dropped below 20 cmHO in 69% of cases.
- * Overall, while cuff pressure varied significantly during surgery, serious complications were rare, highlighting the need for better pressure management during procedures.
Article Abstract
Background: Few studies examined time-to-time changes of cuff pressure of an endotracheal tube during surgery. We retrospectively analyzed the changes of cuff pressure during thyroid surgery and examined its relationships with postoperative airway complications.
Case Presentation: Cuff pressure was initially adjusted at 26 cmHO and continuously measured in 61 patients. The cuff pressure-time curve dynamically fluctuated, and exceeded 30 cmHO in all patients, whereas decreased to ≤ 20 cmH0 in 42 (69%) patients. Ratio of the period with such an increase and decrease of cuff pressure to the total duration of surgery were 40% (28-66%) and 9% (0-21%), respectively (median, interquartile range). No patients showed symptoms of airway stenosis requiring treatment except one who developed recurrent laryngeal nerve palsy. No patients had lower respiratory tract infection.
Conclusions: Cuff pressure dynamically fluctuated during thyroid surgery. Preventing an increase as well as decrease of cuff pressure is required.
