Study of endotracheal tube cuff pressure and time of measurement among intensive care units patients
Authors
Abstract:
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 patients Methods: This study was cross sectional designed to perform on 61 patients with oral intubation in the intensive care units, Rasht educational therapeutic centers, during the summer of 2013 for three months. A manometer was used to measure the cuff pressure twice every 6 hours interval. Different variables like age, sex, diagnosis, Body Mass Index and days intubated also were measured. All data obtained were analyzed using descriptive statistics (mean, standard deviation distribution) and inferential statistics (T test, Pearson, ANOVA) Results: This study indicated that the cuff pressure was normal in 16.4% cases at the first step and after 6 hours, cuff pressure adjustment increased by 78.7%. The results show that correlation between days intubated and cuff pressure (in first evaluation P= 0.002, in second evaluation P=0.01) and BMI (in first evaluation P= 0.007, in second evaluation P=0.03 were significant Conclusion: This study showed that despite of 6 hours cuff pressure control, the range of miss regulation was 21.3%. This issue highlights that to prevent complication due to over and under inflation of cuff, a fewer intervals between cuff pressure control is required

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 ...

CONTEXT High compliance endotracheal tubes cuffs are used to prevent gas leak and also pulmonary aspiration in mechanically ventilated patients. However, the use of the usual cuff inflation volumes may cause tracheal damage. OBJECTIVE We tested the hypothesis that endotracheal tube cuff pressures are routinely high (above 40 cmH2O) in the Post Anesthesia Care Unit (PACU) or Intensive Care Uni...

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...

OBJECTIVES Endotracheal tube cuff (ETTc) inflation by standard methods may result in excessive ETTc pressure. Previous studies have indicated that methods of cuff inflation most frequently used to inflate ETTcs include palpation of the tension in the pilot balloon or injection of a predetermined volume of air to inflate the pilot balloon. If a logarithmic relationship exists between ETTc volume...

abstract background: most of the patients admitted in the intensive care units (icus) require an endotracheal tube and mechanical ventilation. in order to clear and maintain patency of the airways, endotracheal suctioning is required. therefore, the least detrimental way of endotracheal tube suctioning which can diminish the complications should be selected. the present study aimed to compare t...
