Increasing suction pressure during endotracheal suctioning increases the volume of suctioned secretions, but not procedure-related complications: A comparative study in open system endotracheal suctioning.

OBJECTIVES: To compare the effect of three different suction pressures (80 mmHg, 150 mmHg, 250 mmHg) with the open system suction method in terms of the volume of secretions and complications development in intubated intensive care patients. RESEARCH METHODOLOGY/DESIGN: This study was planned as a prospective, experimental, self-controlled design. The study sample included 47 patients. Data were collected using a data collection and patient follow-up form from patient records. SETTING: Single adult intensive care unit in a university hospital. RESULTS: Fifty five percent of the patients were male, 61.7% were older than 65 years and 38.32% had lung infection. The amount of suctioned secretions tended to increase significantly with increasing negative pressure and there was a significant difference between the pressures in terms of the median volume of suctioned secretions (p < 0.001). There was no significant difference between the suction pressures in terms of oxygen desaturation, hypertension rates (p > 0.05). Tachycardia, bradycardia, hypoxaemia, tracheal mucosal damage or mucosal bleeding were not observed during suctioning with three different suction pressures. CONCLUSION: It may be assumed that 250 mmHg suction pressure, via compliance with open system suction method related procedures, is being more effective and equally safe for secretion cleaning in comparison to the 80 and 150 mmHg suction pressures.

Knowledge and practice of intensive care nurses for endotracheal suctioning in a teaching hospital in western Turkey.

OBJECTIVES: This study was conducted to determine intensive care nurses' knowledge and practice levels regarding open system endotracheal suctioning and to investigate if there is a relationship between nurses' demographic characteristics and their knowledge and practice. RESEARCH METHODOLOGY/DESIGN: The study was conducted as a cross-sectional and non-participant structured observational design. Data were collected using a 45-item structured and self-administered questionnaire and a 31-item observational checklist. The study sample included 72 nurses. SETTING: Three adult intensive care units in a teaching hospital. RESULTS: The nurses' mean scores of knowledge and practice were 23.79±3.83 and 12.88±2.53. Their level of knowledge was very good in 59.7%, good in 34.7%, and the level of practice was fair in 79.2% and good in 18.1%. The relationship between the type of unit and the nurses' knowledge scores was statistically significant (p=0.013). The correlation between the nurses' scores of knowledge and practice was not statistically significant (r=0.220; p=0.063). CONCLUSION: This study suggests that the knowledge level of most of the nurses was good and their practice level was fair. Intensive care nurses must perform suctioning procedures safely and effectively to ensure delivery of quality of care and eliminate complications.
