Alternatively, it can be accomplished with a closed suctioning system included in the ventilatory circuit, allowing to introduce the suction catheter into the airways without disconnecting the patient from the ventilator. The closed-suction system has some advantages compared to the conventional, open-suction technique.
When to use a closed suction catheter system? Closed suction catheter systems should be used as the system of choice for patients with an ETT or tracheostomy who require suction. How are open suction systems used in ICU? Closed suction systems CSS enable patients to be suctioned by a suction catheter enclosed within a plastic sleeve, without the need for ventilator disconnection 1. How does a closed suction system CSS work? Post navigation « Previous.
What is the difference between open and closed suctioning? What is a closed suction? What are the advantages of a closed suction system? What are the disadvantages of a closed suction system? The disadvantages of CES include the risk of producing high negative pressures if the amount of air suctioned exceeds the gas flow delivered to the patient by the ventilator;[6] reduced efficiency in clearing thick secretions from the airways;[7] and the high financial cost of the system,[8] which has to be replaced … How does a closed suction drain work?
What are the complications of suctioning? Complications Suctioning can stimulate the vagal nerve, predisposing the patient to bradycardia and hypoxia.
Hypoxia can be profound from occlusion, interruption of oxygen supply, and prolonged suctioning. Mucosal trauma, physical injuries, and bleeding can result from blunt or penetrating trauma. When should a patient suction? Clinicians are advised to check the literature as research may have been published that change these recommendations. Open suction systems OSS refer to a single-use catheter inserted into the ETT either by disconnecting the ventilator tubing or via a swivel connector.
Closed suction systems CSS enable patients to be suctioned by a suction catheter enclosed within a plastic sleeve, without the need for ventilator disconnection 1. Yes indicates where the balance of evidence was in Five systematic reviews SRs and one crossover randomised controlled trial RCT found the incidence of VAP to be independent of the use of either open or closed suction systems Refer to Table 5.
A meta-analysis of nine randomised controlled trial also found no difference between patients managed with open and closed suction systems for the incidence of VAP , patient length of ICU stay or for patient mortality The bulk of existing evidence, regarding colonisation of the tube, as distinct from VAP incidence, weakly favours the use of OSS. Studies highlight variation of health worker clinical practice according to the type of suction system in use.
A recent randomised crossover trial 23 , showed that while CSS minimised lung volume loss, there was a statistically significant longer time to recovery of pre-suction EELV.
CSS has been found to be advantageous for patient oxygenation in the specific scenario of pre-oxygenated acute lung injury patients if followed by a recruitment manoeuvre immediately post suction Methodological quality of this study is questionable as procedures were inconsistently applied.
An SR and a crossover trial 23 found no difference in patient oxygenation with either open or closed suction system use, regardless of pre-oxygenation prior to the suction procedure One interrupted time series provides weak evidence for better sputum clearance with open systems 24 , while an SR has shown no difference in the quantity of secretion removal between open or closed systems used An SR 18 and an observational study 25 both found little effect on heart rate, mean arterial blood pressure or saturated peripheral venous oxygen content SpO 2 on the patient with the use of either open or closed suction systems.
Patient outcome measures investigated include duration of mechanical ventilation, length of ICU stay, and mortality. Across all three indicators no difference was found within 2 x systematic reviews 18, 20 , and 1 x RCT One meta-analysis found a higher association between CSS and mechanical ventilation duration Use of disposable suction catheters for OSS in short-term ventilation i.
One SR also found savings in nursing time with CSS use for patients ventilated for greater than four days. These findings were attributable to two personnel required for patient disconnection from the circuit if using an open system The information on this page is general in nature and cannot reflect individual patient variation.
