RESUMO
BACKGROUND: Several studies have revealed that clinicians cannot suction all available secretion in the trachea and perform more frequent suctioning with a closed suctioning system (CSS) than with an open suctioning system (OSS). There are also studies claiming that the CSS is as effective as the OSS, based on either the amount of secretion, the frequency of suctioning, or haemodynamic parameters alone. However, there is no study examining all at once. OBJECTIVES: This study aims to determine whether the CSS is as effective for secretion removal, suctioning frequency, tidal volume (VT), and peripheral oxygen saturation (SpO2) as the OSS. METHODS: The study used a single-blind, randomised, 2 × 2 crossover (2-method, 2-arm, 2-period) design. One hundred intubated patients were randomly assigned to two study arms. Thirty-four were randomised to the CSS on the first day and the OSS on the second day (AB arm), and 35 were randomised to the OSS on the first day and the CSS on the second day (BA arm). A 12-h washout period was set between them. Haemodynamic parameters were measured just before suctioning and in the 5th minute after suctioning. The secretions obtained after suctioning were weighed, and the frequency of suctioning was recorded. RESULTS: There were no effects of method, period, or carryover on suctioning frequency and amount of secretion in the 2 × 2 crossover design t-test (p > 0.05). In the OSS, there was a weak, linear, and negative correlation between the amount of secretion and SpO2, and between VT and SpO2 measured before and after suctioning (p < 0.05 for all). CONCLUSIONS: Open and closed suctioning systems were similar in terms of haemodynamic alterations, amounts of secretion, and frequency of suctioning. The CSS was as effective as the OSS.

Background: Endotracheal suctioning (ETS) is one of the most frequently performed invasive procedures in intensive care units (ICUs). This audit was aimed at studying current practices and knowledge regarding ETS in the Indian critical care setup, with the background aim of raising awareness regarding correct practices as per current recommendations in critically ill patients. Materials and methods: After registering the trial with the clinical trial registry, India, a structured audit questionnaire containing 20 questions pertaining to ETS was distributed through electronic media among resident doctors working in the ICUs across India. Responses received were statistically analyzed. Results: The questionnaire was sent to 530 clinicians, of which only 200 (37.73%) responded. The audit revealed that only 22% respondents set the maximum negative pressure every time before suctioning, on the suction apparatus and only 32% said they would choose a catheter size of less than half the internal diameter of the endotracheal tube (ETT). About 90% of the respondents did not routinely do any form of documentation of the ETS. Almost 72% of the responders opined that closed suction systems reduce the chances of developing ventilator-associated pneumonia (VAP). Only 46% of respondents thought that no solution should be routinely instilled in ETT during ETS. Conclusion: There is lack of awareness regarding frequency and technique of ETS, infection control and monitoring required during ETS. Institutional protocols should be in place to follow correct guidelines for performing ETS. How to cite this article: Singh R, Bhalotra AR, Sharma S.

RESUMO
BACKGROUND: To investigate whether the administration of intravenous propofol before endotracheal suctioning (ES) in patients with severe brain disease can reduce the sputum suction response, improve prognosis, and accelerate recovery. METHODS: A total of 208 severe brain disease patients after craniocerebral surgery were enrolled in the study. The subjects were randomly assigned to the experimental group (n = 104) and the control group (n = 104). The experimental group was given intravenous propofol (10 ml propofol with 1 ml 2% lidocaine), 0.5-1 mg/kg, before ES, while the control group was subjected to ES only. Changes in vital signs, sputum suction effect, the fluctuation range of intracranial pressure (ICP) before and after ES, choking cough response, short-term complications, length of stay, and hospitalization cost were evaluated. Additionally, the Glasgow Outcome Scale (GOS) prognosis score was obtained at 6 months after the operation. RESULTS: At the baseline, the characteristics of the two groups were comparable (P > 0.05). The increase of systolic blood pressure after ES was higher in the control group than in the experimental group (P < 0.05). The average peak value of ICP in the experimental group during the suctioning (15.57 ± 12.31 mmHg) was lower than in the control group (18.24 ± 8.99 mmHg; P < 0.05). The percentage of patients experiencing cough reaction- during suctioning in the experimental group was lower than in the control group (P < 0.05), and the fluctuation range of ICP was increased (P < 0.0001). The effect of ES was achieved in both groups. The incidence of short-term complications in the two groups was comparable (P > 0.05). At 6 months after the surgery, the GOS scores were significantly higher in the experimental than in the control group (4-5 points, 51.54% vs. 32.64%; 1-3 points, 48.46% vs. 67.36%; P < 0.05). There was no significant difference in the length of stay and hospitalization cost between the two groups. CONCLUSIONS: Propofol sedation before ES could reduce choking cough response and intracranial hypertension response. The use of propofol was safe and improved the long-term prognosis. The study was registered in the Chinese Clinical Trial Registry on May 16, 2015 (ChiCTR-IOR-15006441).

BACKGROUND: Endotracheal suctioning (ES) provokes a cumulative hemodynamic response by activation of sympathetic and parasympathetic circuits in the central nervous system. In this proof-of-concept study, we aimed to analyze hemodynamic changes during ES in ventilated subarachnoid hemorrhage (SAH) patients and investigated whether the associated hemodynamic changes relate to the time to arousal and functional outcome. METHODS: For the current observational study, 191 SAH patients admitted to the neurological intensive care unit of a tertiary hospital requiring mechanical ventilation were included. One thousand eighty ES episodes during the first 72 h of admission were analyzed. Baseline median heart rate (HR) and mean arterial pressure (MAP) were compared to peak HR and MAP during ES based on 5-min averaged data (ΔHR and ΔMAP). Multivariable analysis to assess associations between ΔHR and ΔMAP and time to arousal (time to Richmond Agitation Sedation Scale ≥ 0, RASS) and poor functional outcome (modified Rankin Scale Score > 2, mRS) was performed using generalized estimating equations. RESULTS: Patients were 59 (IQR, 50-70) years old and presented with a median admission H&H grade of 4 (IQR, 3-5). In-hospital mortality was 22% (25% at 3 months) and median time to arousal was 13 (IQR, 4-21) days. HR increased by 2.3 ± 7.1 beats per minute (bpm) from 75.1 ± 14.8 bpm at baseline. MAP increased by 3.2 ± 7.8 mmHg from baseline 80.9 ± 9.8 mmHg. In multivariable analysis, ΔHR (p < 0.001) was significantly lower in patients who regained consciousness at a later time point and a lower ΔHR was associated with poor functional 3-month outcome independent of RASS (adjOR = 0.95; 95% CI = 0.93-0.98) or midazolam dose (adjOR = 0.96; 95% CI = 0.94-0.98). ΔMAP was neither associated with the time to regain consciousness (p = 0.087) nor with functional outcome (p = 0.263). CONCLUSION: Augmentation in heart rate may quantify the hemodynamic response during endotracheal suctioning in brain-injured patients. The value as a biomarker to early discriminate the time to arousal and functional outcome in acutely brain-injured patients needs prospective confirmation.

INTRODUCTION: Ventilator-associated pneumonia, a common cause of mortality and morbidity, is commonly seen among patients with endotracheal intubation due to unsafe suctioning practices by health professionals. OBJECTIVE: A systematic review was conducted to explore the gaps in the existing practices of nurses and thus proposing comprehensive guidelines for safe practice. MATERIALS AND METHODS: A two-phase strategy was adopted to identify the studies through a comprehensive electronic search in PubMed, Google Scholar, ProQuest, Ovid, and Helinet Summon by using predefined keywords within a year limit of 2002-2016. The quality of studies was reviewed using tools endorsed by Joanna Briggs Institute. This review was conducted according to the guidelines described in the preferred reporting items for systematic reviews and meta-analyses (PRISMA). Qualitative data were described through the process of metasynthesis. Quantitative analysis was performed to combine the competent quantitative evidences to identify knowledge and practices of endotracheal suctioning (ETS). RESULTS: Thirty studies had been subjected for metasynthesis, among which six provided relevant information for quantitative analysis. Quantitative analysis of the studies reported that only 36% of the nurses had assessed patients prior to suctioning and had knowledge about the size of the suction catheter while only 46% were aware of the appropriate suction pressure to be used for ETS. Handwashing compliance prior to suctioning was observed in only 62% of the nurses. It is reported that, despite the awareness on possible complications, nurses fail to adhere to the recommended practice guidelines. CONCLUSION: The current review would explore the best evidence-based practices (EBPs) among nurses related to ETS, which would ensure quality care to critically ill patients.

RESUMO
The current version of Neonatal Resuscitation Program no longer favors routine endotracheal suctioning (ETS) in non-vigorous newborns with meconium-stained amniotic fluid (MSAF) due to possibility of procedure-related harms and questionable benefits. However, it calls for additional research on this procedure to provide a definitive answer. The present study was conducted to evaluate the role of ETS in non-vigorous neonates of ≥ 34 weeks' gestation born through MSAF on the incidence of meconium aspiration syndrome (MAS). In this open-label randomized controlled trial, 132 non-vigorous neonates with MSAF were randomized to receive ETS (n = 66) or no-ETS (n = 66) during delivery room resuscitation (DRR). Primary outcome variable was incidence of MAS. Secondary outcome variables were requirement of DRR, need of respiratory support, development of complications, duration of hospitalization, and mortality. Both the groups were comparable with respect to maternal and neonatal characteristics. Incidence of MAS was 21 (31.8%) and 15 (22.7%) cases in ETS and no-ETS groups, respectively (relative risk (RR), 1.400, 95% confidence interval (CI), 0.793-2.470). The two groups did not differ with regard to DRR, need for respiratory support, and development of complications. Nine (13.6%) neonates in ETS group, and 5 (7.5%) in no-ETS group died (p > 0.05). Median (interquartile range) duration of hospital stay was 54 (31-141) h and 44 (26-102) h in ETS and no-ETS groups, respectively (p > 0.05).Conclusions: Routine ETS at birth is not useful in preventing MAS in non-vigorous neonates of ≥ 34 weeks' gestation born through MSAF.Trial registration: Clinical Trials Registry of India (CTRI/2015/04/008819).What is Known:⢠Routine endotracheal suctioning is of questionable benefit in non-vigorous newborns with meconium stained amniotic fluid and may have a possibility of procedure-related harms.What is New:⢠Routine endotracheal suctioning at birth is not useful in preventing meconium aspiration syndrome in non-vigorous newborns of ≥ 34 weeks' gestation born through meconium stained amniotic fluid.

PURPOSE: This study aimed to adapt a guideline for endotracheal suctioning of adults with artificial airways in the perianesthesia setting in China. DESIGN: This study was guided by the ADAPTE framework. METHODS: The development process consisted of setup, adaptation, and finalization phases. A heterogeneous consultant panel that included a patient representative was established to contribute guidance and suggestions regarding guideline development. Relevant evidence documents were searched, critically appraised, selected, and synthesized to develop the draft guideline. After revisions, the adapted guideline was evaluated by 20 external reviewers. FINDINGS: A 155-page adapted guideline was developed with 26 key recommendations (including 3 procedure phases and 17 points of care). CONCLUSIONS: The adapted guideline provided the best evidence for endotracheal suctioning of adults with artificial airways and supported practitioner decisions about appropriate endotracheal suctioning practices for this population. The study also lays the groundwork for future projects on quality improvement and knowledge translation.

BACKGROUND: The insertion of suction devices through endotracheal tubes (ETTs) increases airway resistance and the subsequent suctioning may reduce airway pressures and facilitate atelectasis. The aim of this study was to investigate how airway pressures and tidal volumes change when different combinations of suction equipment and ETT sizes are used, and to what extent unfavorable effects can be ameliorated by choice of ventilator settings. METHODS: A mechanical ventilator was connected to a lung model by ETTs of 9 mm, 8 mm or 7 mm internal diameter (ID) with a pressure transducer inserted distal to the ETT. The effects of suction procedures with bronchoscope and closed catheter systems were investigated during pressure controlled ventilation (PCV) and volume controlled ventilation (VCV). In each mode, the effects of changes in inspiration:expiration (I:E) ratio, trigger sensitivity and suction pressure were examined. RESULTS: The variables that contributed most to negative model airway pressures and loss of tidal volume during suctioning were (in descending order); 1) Small-size ETTs (7-8 mm ID) combined with large diameter suction devices (14-16 Fr); 2) inverse I:E ratio ventilation (in VCV); 3) negative ventilator trigger sensitivity; and 4) strong suction pressure. The pressure changes observed distal to the ETTs were not identical to those detected by the ventilator. CONCLUSIONS: Negative model airway pressure was induced by suctioning through small-size ETTs. The most extreme pressure and volume changes were ameliorated when conventional ventilator settings were used, such as PCV mode with short inspiration time and a trigger function sensitive to flow changes.

BACKGROUND: A common procedure within intensive care units (ICUs) is the suctioning of respiratory secretions in patients who have been intubated or who have undergone tracheostomy. Previous studies have shown a wide variation in suctioning practices, and although current evidence does not support the routine practice of normal saline instillation (NSI), anecdotally, this is believed to be a common practice. OBJECTIVE: To examine the suctioning practices of registered nurses (RNs) and registered respiratory therapists (RRTs) in six hospital ICUs in Ontario, with special attention devoted to the use of NSI. METHODS: A 24-question, self-administered survey was distributed to 180 participants (90 RNs and 90 RRTs) working in the ICU of six hospitals in Ontario. The survey addressed individual suctioning practices within the ICU. RESULTS: The survey response rate was 96%. There were many similarities between the RRT and RN groups, with both reporting high use of NSI. Both groups observed side effects following NSI with suctioning including decreased oxygen saturation, patient agitation and increased volume of secretions. A significant number of participants from both the RN and RRT groups were unaware of the existence of suctioning and/or NSI protocols in the ICU. Some respondents reported that they routinely suctioned mechanically ventilated patients rather than as required. CONCLUSION: RNs and RRTs continue to practice NSI despite evidence-based practice guidelines suggesting that this therapy may be detrimental to patients. Increased awareness of best practices with respect to endotracheal tube suction generally, and NSI specifically, should be the focus of professional education in both groups of ICU staff.
HISTORIQUE: À l'unité de soins intensifs (USI), on aspire souvent les sécrétions respiratoires des patients intubés ou trachéostomisés. Des études antérieures ont démontré une importante variation des pratiques d'aspiration, et même si les données actuelles n'appuient pas le rinçage systématique par solution physiologique normale (SPN), les données empiriques révèlent que leur utilisation serait courante. OBJECTIF: Examiner les pratiques d'aspiration des infirmières et des inhalothérapeutes à l'USI de six hôpitaux de l'Ontario et s'attarder particulièrement à l'utilisation de la SPN. MÉTHODOLOGIE: Les chercheurs ont distribué un sondage auto-administré de 24 questions à 180 participants (90 infirmières et 90 inalhothérapeutes) qui travaillaient à l'USI de six hôpitaux de l'Ontario. Ce sondage traitait des pratiques d'aspiration individuelles à l'USI. RÉSULTATS: Le taux de réponse au sondage s'élevait à 96 %. Les groupes d'infirmières et d'inhalothérapeutes présentaient surtout des similarités, tous deux déclarant une forte utilisation du SPN. Les deux groupes observaient des effets secondaires après l'administration du SPN, l'aspiration entraînant une diminution de la saturation en oxygène, une agitation des patients et une augmentation du volume de sécrétions. Bon nombre des participants des deux groupes ne connaissaient pas de protocoles d'aspiration ou d'utilisation de la SPN à l'USI. Certains répondants précisaient qu'ils procédaient à l'aspiration systématique des patients sous ventilation mécanique plutôt que d'attendre les besoins. CONCLUSION: Les infirmières et les inhalothérapeutes continuent d'administrer un SPN malgré les directives cliniques fondées sur des données probantes indiquant qu'elle peut être néfaste au patient. La formation professionnelle de ces deux groupes d'employés de l'USI devrait s'attarder sur les pratiques exemplaires en matière d'aspiration des sondes trachéales en général et de l'administration de SPN en particulier.
RESUMO
AIM AND OBJECTIVES: To investigate the effects of expiratory ribcage compression (ERCC) before endotracheal suctioning on the arterial blood gases (ABG) in patients receiving mechanical ventilation. BACKGROUND: Endotracheal suctioning is one of the most frequently used methods for airway clearance in patients receiving mechanical ventilation. Chest physiotherapy techniques such as ERCC before endotracheal suctioning can be used as a means to facilitate mobilizing and removing airway secretions and improving alveolar ventilation. DESIGN: A prospective, randomized, controlled cross-over design. METHODS: A randomized controlled cross-over trial with a convenience sample of 70 mechanically ventilated patients was conducted from 2006 to 2007. The patients received endotracheal suctioning with (experiment-period) or without (control-period) an antecedent 5-min expiratory ribcage. All the patients experienced both periods with at least a 3-h washed-out interval between the two periods. ABG were measured 5 min before and 25 min after endotracheal suctioning. RESULTS: The statistical tests showed that the levels of partial pressure of oxygen (PaO2 )/fraction of inspired oxygen (FiO2 ), partial pressure of carbon dioxide (PaCO2 ) and arterial oxygen saturation (SaO2 ) in the experimental period at 25 min after the intervention were significantly different from the control period. The tests also revealed that the levels of these variables at 25 min after suctioning were also significantly different from baseline values. However, these differences were clinically significant only for PaO2 /FiO2 . CONCLUSION: By improving the levels of PaO2 /FiO2 , ERCC can reduce the patients' need for oxygen and hence it can at least reduce the side effects of oxygen therapy. RELEVANCE TO CLINICAL PRACTICE: Improving PaO2 /FiO2 levels means less need for oxygen therapy. Hence, by applying ERCC we can at least minimize the side effects of oxygen therapy.

BACKGROUND: Endotracheal suctioning causes discomfort, is associated with adverse effects, and is resource-demanding. An artificial secretion removal method, known as an automated cough, has been developed, which applies rapid, automated deflation, and inflation of the endotracheal tube cuff during the inspiratory phase of mechanical ventilation. This method has been evaluated in the hands of researchers but not when used by attending nurses. The aim of this study was to explore the efficacy of the method over the course of patient management as part of routine care. METHODS: This prospective, longitudinal, interventional study recruited 28 subjects who were intubated and mechanically ventilated. For a maximum of 7 d and on clinical need for endotracheal suctioning, the automatic cough procedure was applied. The subjects were placed in a pressure-regulated ventilation mode with elevated inspiratory pressure, and automated cuff deflation and inflation were performed 3 times, with this repeated if deemed necessary. Success was determined by resolution of the clinical need for suctioning as determined by the attending nurse. Adverse effects were recorded. RESULTS: A total of 84 procedures were performed. In 54% of the subjects, the artificial cough procedure was successful on > 70% of occasions, with 56% of all procedures considered successful. Ninety percent of all the procedures were performed in subjects who were spontaneously breathing and on pressure-support ventilation with peak inspiratory pressures of 20 cm H2O. Rates of adverse events were similar to those seen in the application of endotracheal suctioning. CONCLUSIONS: This study solely evaluated the efficacy of an automated artificial cough procedure, which illustrated the potential for reducing the need for endotracheal suctioning when applied by attending nurses in routine care.

BACKGROUND: This scoping review was conducted to summarise and map studies on pain resulting from endotracheal suctioning in paediatric intensive care patients. METHOD: This scoping review conducted in June 2022 was performed by screening articles published in English. Scopus, PubMed, Cochrane, Web of Science, MedLine and Ovid databases were used for screening. The keywords 'endotracheal suctioning', 'pain', 'paediatric intensive care' and their synonyms were used in the search. RESULTS: During the review, 280 articles were accessed, and the full texts of 14 articles were evaluated for suitability. After some of the articles were excluded from the study, abstracts of nine articles were given below. CONCLUSION: It is recommended that a greater number of randomised controlled studies should be conducted, because the number of studies with a high level of evidence on the effect of endotracheal suctioning on the pain levels of patients in the paediatric intensive care unit is very few.

Endotracheal suctioning is an essential but labor-intensive procedure, with the risk of serious complications. A brand new automatic closed-suction device was developed to alleviate the workload of healthcare providers and minimize those complications. We evaluated the clinical efficacy and safety of the automatic suction system in mechanically ventilated patients with pneumonia. In this multicenter, randomized, non-inferiority, investigator-initiated trial, mechanically ventilated patients with pneumonia were randomized to the automatic device (intervention) or conventional manual suctioning (control). The primary efficacy outcome was the change in the modified clinical pulmonary infection score (CPIS) in 3 days. Secondary outcomes were the frequency of additional suctioning and the amount of secretion. Safety outcomes included adverse events or complications. A total of 54 participants, less than the pre-determined number of 102, were enrolled. There was no significant difference in the change in the CPIS over 72 h (-0.13 ± 1.58 in the intervention group, -0.58 ± 1.18 in the control group, p = 0.866), but the non-inferiority margin was not satisfied. There were no significant differences in the secondary outcomes and safety outcomes, with a tendency for more patients with improved tracheal mucosal injury in the intervention group. The novel automatic closed-suction system showed comparable efficacy and safety compared with conventional manual suctioning in mechanically ventilated patients with pneumonia.
RESUMO
BACKGROUND: Endotracheal suctioning in intubated or tracheotomized critically ill patients is a daily task of various professional groups in intensive and emergency medicine; however, a German language summary of current evidence is lacking. OBJECTIVE: The aim is to develop a narrative overview of current evidence on endotracheal suctioning of intubated or tracheotomized patients in the clinical setting. MATERIAL AND METHODS: A literature search was conducted in the databases Cinahl, Cochrane Library, Livivo, and Medline via PubMed by nurses with an academic degree. In addition, a hand search and applying the snowball principle were performed. Following a successful critical appraisal, all English and German language publications addressing endotracheal suctioning in the context of hospital care were included. RESULTS: A total of 23 full texts were included. After developing 6 main topics on endotracheal suction 19 articles were considered in the reporting. The results showed, among others, that routine deep suctioning once per shift is contraindicated and that the catheter should be advanced no more than 0.5-1â¯cm beyond the distal end of the tube or tracheal cannula. Closed suction catheters offer advantages, especially for staff protection, although studies are heterogeneous. Further training of staff is obligatory. CONCLUSION: Few conclusive studies on endotracheal suction could be found; however, with the available evidence initial conclusions can be drawn which should be considered in, for example, internal standard operating procedures. Further research is needed.

AIM: To review and analyse the evidence on the efficacy and safety of non-pharmacological interventions for preterm infants to relieve endotracheal suctioning (ES) pain. DESIGN: A systematic review per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. METHODS: Six databases were searched with a retrieval strategy. Parallel and crossover randomized controlled trials reporting non-pharmacological interventions for relieving ES pain in preterm infants were identified from inception to 1 September 2021. The protocol was published in PROSPERO (CRD42021276058). RESULTS: Ten studies were retrieved, including nine different non-pharmacological interventions. Seven studies reported that non-pharmacological interventions in relieving pain were more effective than conventional care during ES, and three trials reported its safety. Due to the heterogeneity of pain assessment tools, time of assessment and population, only Facilitated tucking had sufficient evidence that it is a safe and effective non-pharmacological intervention.

BACKGROUND: Endotracheal suctioning is resource demanding, causes patient discomfort, and is associated with adverse effects. A new artificial cough method has been developed for automated secretion removal by using rapid deflation and inflation of the endotracheal tube cuff during the inspiratory phase of mechanical ventilation. This method has been evaluated in a bench model and in animals but not in human subjects. The aim of this study was to investigate whether this method can remove the need for endotracheal suctioning in subjects and whether this is dependent on ventilator settings. METHODS: This prospective, non-controlled study recruited 20 subjects on invasive mechanical ventilation. On the clinical need for endotracheal suctioning, the automatic cough procedure was applied 3 times over 30 s, with this repeated at higher ventilatory pressure and lower respiratory frequency if considered unsuccessful. Success was determined by removal of the clinical need for suctioning. Subject safety and comfort was measured by using the Critical-Care Pain Observation Tool before and after the procedure, and negative effects were recorded. To assess intra-subject variability, the procedure was performed on 3 different occasions for each subject. RESULTS: The procedure was successful in 18 of 20 subjects (90%), with mean subject success rates of 53% at low settings (peak inspiratory pressure 21.8 ± 3.8 cm H2O) and 83% at high settings (peak inspiratory pressure 25.6 ± 3.6 cm H2O). The Critical-Care Pain Observation Tool category remained unchanged in 30 procedures (77%), improved in 7 (18%), and deteriorated in 2 (5%). CONCLUSIONS: This study illustrated the potential for significant reduction in the clinical need for endotracheal suctioning after the use of an automated artificial cough procedure at both low and high peak inspiratory pressures, and that was well tolerated.

Airway suctioning is routinely performed in the majority of care circumstances, including acute care, subacute care, home-based settings, and long-term care. Using an artificial airway to suction the patient allows for the mobilization and evacuation of secretions. When a patient can't independently remove all of the secretions from their respiratory tract, suction is used. This can occur when the body produces excessive secretion or it is not eliminated quickly enough, causing the respiratory system's upper and lower respiratory secretions to accumulate. Airway blockage and inadequate breathing may result from this. Ultimately, this leads to a shortage of oxygen and carbon dioxide from the air, both of which are necessary for ideal cellular activity. Artificial airway suctioning is one of the most crucial components of airway care and a core competency for medical professionals trying to ensure airway patency. Artificial airway suctioning is a standard treatment carried out every day globally and is frequently done in both outpatient and inpatient patients. Therefore, specialists must know the safest and most efficient ways to perform surgery and any potential side effects. In ventilated infants and children, the removal of obstructive secretions by endotracheal suctioning is frequently done. It is unknown how suctioning affects the mechanics of breathing. This study used a prospective observational clinical design to examine the immediate impact of airway resistance in endotracheal suctioning, tidal volume, and dynamic lung regulation in mechanically ventilated adult patients and mechanically ventilated pediatric patients. The preparation, process, and indications for intraoperative fusion treatment in various circumstances are covered in this systematic review.
RESUMO
Background: Endotracheal suctioning of mechanically ventilated patients differs across the world. In many low and middle-income countries, endotracheal suctioning is often performed with a sterile suctioning catheter that is used for 12 h or during the length of one nursing shift. The effect of flushing multiple used endotracheal suction system with chlorhexidine after suctioning to reduce ventilator associated pneumonia (VAP) remains unclear. Aim: The aim of the study is to assess the effectiveness of flushing multiple-used open endotracheal suction catheters and suctioning system with chlorhexidine gluconate 0.2% to reduce VAP in mechanically ventilated patients in a resource-limited Intensive Care Unit (ICU). Methods: Due to the difficulty of blinding the intervention for nurses who perform endo-tracheal suction procedures, we adopted a quasi-experimental method with a randomized controlled trial design. A sample of 136 ICU patients were allocated to the intervention (n = 68) or control group (n = 68) between May and November 2020. The intervention was flushing the multiple-used suction catheter and suction system with 40ml chlorhexidine gluconate 0.2% and in the control group we used normal saline to flush the catheter and suction system. The primary outcome was incidence of VAP and the cost of the flushing solutions was the secondary outcome measure. Results: Patients in the intervention group had a lower incidence of VAP compared to patients in the control group; 15 (22.1%) vs 29 (42.6%), p = 0.01. The incidence of late-onset VAP was 26.2% in the intervention group and 49% in the control group (p = 0.026) and the early-onset VAP was 13.2% in the intervention group and 25% in the control group (p = 0.081). Chlorhexidine gluconate 0.2% reduced the cost of suction system flushing (median: 78.4 vs 300 EGP, p < 0.001). Conclusion: Using chlorhexidine gluconate 0.2% to flush multiple-used suctioning catheters after every endo-tracheal suction procedure might reduce the incidence of VAP in mechanically ventilated patients. Chlorhexidine gluconate 0.2% can be a cost-effective solution for flushing the suction circuit. Nurses working in resource-limited ICUs and using suctioning catheters multiple times might consider using chlorhexidine gluconate 0.2% instead of normal saline or distilled water when flushing the suction system.

RESUMO
BACKGROUND: The increase in admissions to intensive care units (ICUs) in 2020 and the morbidity and mortality associated with SARS-CoV-2 infection pose a challenge to the analysis of evidence of health interventions carried out in ICUs. One of the most common interventions in patients infected with the virus and admitted to ICUs is endotracheal aspiration. Endotracheal suctioning has also been considered one of the most contaminating interventions. OBJECTIVE: This review aims to analyze the benefits and risks of endotracheal suctioning using closed suction systems (CSS) in COVID-19 patients. METHODS: A rapid review was carried out using the following databases: PubMed, MEDLINE, CINAHL, LILACS, the Cochrane Library, and IBECS. The data search included articles in English and Spanish, published between 2010 and 2020, concerning adult patients, and using the key words "endotracheal," "suction," and "closed system." RESULTS: A total of 15 articles were included. The benefits and risks were divided into 3 categories: patient, care, and organization. Relating to the patient, we found differences in cardiorespiratory variables and changes in the ventilator, for example, improvement in patients with elevated positive and end-expiratory pressure due to maladaptation and alveolar collapse. Relating to care, we found a shorter suctioning time, by up to 1 minute. Relating to organization, we found fewer microorganisms on staff gloves. Other conflicting results between studies were related to ventilator-associated pneumonia, bacterial colonization, or mortality. CONCLUSIONS: Aside from the need for quality research comparing open suction systems and CSS as used to treat COVID-19 patients, closed endotracheal suctioning has benefits in terms of shorter stay in the ICU and reduced environmental contamination, preventing ventilator disconnection from the patient, reducing the suctioning time-though it does produce the greatest number of mucosal occlusions-and preventing interpatient and patient-staff environmental contamination. New evidence in the context of the SARS-CoV-2 virus is required in order to compare results and establish new guidelines.
RESUMO
Airway secretions may increase in intubated patients due to the impaired mucociliary clearance, impaired cough reflex, abnormal glottic function, insufficient moisturizing, and respiratory tract infections. As with any intervention, patients should be cautiously monitored for possible complications during the endotracheal suctioning. Procedure-related changes in the cerebral and somatic tissue oxygenation, hemodynamics, and oxygen saturation can be observed in these patients. It is important to ensure maintenance of tissue oxygenation during these and other interventions performed in critically ill children. The aim of this study was to investigate the effects of the endotracheal suctioning on tissue oxygenation in patients undergoing mechanical ventilation in the pediatric intensive care unit. Cerebral and somatic near-infrared spectroscopy (NIRS) monitoring were performed noninvasively using standardized NIRS equipment as a means of monitoring regional tissue oxygenation. Vital signs, level of sedation, pain scores, and somatic and cerebral tissue oxygenation values of mechanically ventilated patients were recorded prospectively 5 minutes before, during, and after endotracheal suctioning. Cerebral NIRS measurements did not exhibit any statistically significant changes during endotracheal suctioning. Somatic NIRS levels changed significantly before, during, and after endotracheal suctioning and remained low throughout the procedure. Endotracheal suctioning is an invasive intervention that facilitates clearance of tracheal secretions and maintenance of the oxygenation and ventilation. The maintenance of the tissue oxygenation should be documented during these and other interventions performed on critically ill children. Somatic NIRS is a useful tool for monitoring tissue oxygenation during such procedures.
