abstract

background untrained fingertip palpation has been shown to be unable to adjust endotracheal tube (et) cuff pressure in most intubated patients. objective we determined the impact of a training course of ett cuff adjustment by palpation in attaining a safe cuff inflation pressure. patients and methods twenty-five nurses were asked to adjust the ett cuff pressure to 25 cmh2o by palpation on three different patients in seven sessions (s1-s7): before training, two hours and two days after first training session, and two hours, two days, one week, and eight months after second training session. results before training, 41.3% of the cuff pressures were adjusted to the safe range of 21-35 cmh2o. the pressures obtained in s2-s7 were lower and less variable than s1 (p = 0.02 to < 0.0001). after the first training session, all the ett cuff pressures in the high range (36-50 cmh2o) and 87.5% in the very high range (> 50 cmh2o) changed to the safe range. conclusions using trained fingertip adjustment of the ett cuff pressure throughout the nursing shift with protocols for the adjustment of out of range pressures at the beginning of each shift by cuff manometer could decrease the rate of ett cuff over- and under-inflation.

Study of endotracheal tube cuff pressure and time of measurement among intensive care units patients

Introduction: The pressure in the endotracheal tube cuff must be kept within an optimal range, to make sure tracheal capillaries circulation still stable during positive ventilation. This is essential to avoid oral and gastric stuffing aspiration Objective: The objective of this study was to assess the endotracheal tube cuff pressure and time intervals measurements among intensive care units...

Microbial colonization of endotracheal tube in intensive care unit patients

Microbial biofilms has remained a major complication of tracheal intubation in patients requiring ventilator equipment. The aim of this study was to characterize bacterial and fungal biofilms in endotracheal tubes from intensive care unit (ICU) patients in Ahwaz, Iran. In this cross-sectional descriptive study, patients admitted to ICU that required mechanical ventilation for at least 24 hours ...

Cuff pressure control in intensive care unit: training effects.

OBJECTIVES Direct cuff pressure to the tracheal wall can cause damage. This paper aimed to verify the effectiveness of nursing team training on cuff pressure control. METHODS A retrospective survey was initially made on the records of cuff pressure measurements from January 2007 to June 2008 and the inadequacy percent was verified. Next, a nursing team training program was provided involving ...

Identification of a Very High Cuff Pressure by Manual Palpation of the External Cuff Balloon on an Endotracheal Tube.

The most common complication due to intubation is a high cuff pressure. A high cuff pressure can cause postanesthetic tracheal mucosal injuries in patients undergoing surgery. The aim of this cross-sectional study was to describe whether anesthetic nurses and anesthesiologists identified a very high cuff pressure by manual palpation of the external cuff balloon on an endotracheal tube. An airwa...

endotracheal tube cuff pressure assessment: education may improve but not guarantee the safety of palpation technique

conclusions implementing educational programs with the introduction of estimation techniques besides the use of manometer as a standard intraoperative monitoring will improve the safety of the practice. results the mean etcp after the in vitro survey was significantly lower than the mean etcp before the intervention (45 ± 13 vs. 51 ± 15 cm h2o, p = 0.002). the rate of measurements within the sa...
