Prevention of Endotracheal Tube-Related Pressure Injury: A Systematic Review and Meta-analysis

Characteristics of oral mucosal pressure injuries in children with orotracheal intubation in intensive care units: An observational study

BACKGROUND

Tracheal intubation can be used for ventilation to ensure an unobstructed respiratory tract, and it is the most common respiratory support technique used in paediatric intensive care unit (PICU) patients. Orotracheal intubation is usually the preferred method of tracheal intubation. However, it can cause stress-related damage to the oral mucosa. Identifying the factors that cause oral mucosal pressure injury (OMPI) can prevent its occurrence in children with oral endotracheal intubation.

AIMS

To examine the characteristics of OMPI in children who underwent orotracheal intubation in the PICU and to assess their influencing factors.

STUDY DESIGN

An observational, prospective study. Data were gathered from the PICU of a tertiary hospital in China between January 2023 and October 2023. The patient data were obtained from the 'General Information Questionnaire', 'Paediatric Critical Illness Score', 'STRONGkids Scale' and 'OMPI Staging and Assessment Tools'. Data analysis was subsequently performed using univariate and logistic regression analyses.

RESULTS

A total of 187 children who underwent orotracheal intubation were analysed. During the observation period, 44.92% (n = 84) of the children developed OMPI. It comprised 63.10% (n = 53) of stage I injuries, 33.33% (n = 28) of stage II injuries and 3.57% (n = 3) of stage III injuries. The common injury sites were the lower jaw (48.81%), upper jaw (29.76%), tongue (20.24%) and joints (10.71%). The logistic regression analysis results revealed that high critical illness (OR = 0.835, 95% CI: 0.726-0.961), long intubation time (OR = 1.043, 95% CI: 1.021-1.067), prone ventilation (OR = 6.708, 95% CI: 1.421-31.670), hypothermia (OR = 5.831, 95% CI: 1.208-28.149), use of dental pads (OR = 5.520, 95% CI: 1.150-26.487) and low albumin levels (OR = 6.238, 95% CI: 1.285-30.281) were the main contributing factors for OMPI in children with orotracheal intubation (p < .05).

CONCLUSIONS

The occurrence of OMPI in children who underwent orotracheal intubation in the PICU was notable and was predominantly observed in stages I and II. Consequently, clinical nursing personnel should proactively recognize risk factors and administer timely interventions to mitigate the occurrence of OMPI in such children.

RELEVANCE TO CLINICAL PRACTICE

The incidence of OMPI in children who underwent orotracheal intubation was relatively high. Nurses and doctors should closely monitor the risk factors for orotracheal intubation in children to prevent the occurrence of OMPI.

Physical and Cognitive Impairment in Acute Respiratory Failure

Recent research has brought renewed attention to the multifaceted physical and cognitive dysfunction that accompanies acute respiratory failure (ARF). This state-of-the-art review provides an overview of the evidence landscape encompassing ARF-associated neuromuscular and neurocognitive impairments. Risk factors, mechanisms, assessment tools, rehabilitation strategies, approaches to ventilator liberation, and interventions to minimize post-intensive care syndrome are emphasized. The complex interrelationship between physical disability, cognitive dysfunction, and long-term patient-centered outcomes is explored. This review highlights the need for comprehensive, multidisciplinary approaches to mitigate morbidity and accelerate recovery.

Incidence, severity and characteristics of medical device-related pressure injuries in adult intensive care patients: A single-centre, cross-sectional study

AIM

This study aimed to determine the incidence, severity and characteristics of medical device-related pressure injuries in intensive care units.

METHODS

This is a cross-sectional study. Data were collected from 187 patients admitted to the Anaesthesia and Reanimation intensive care unit of a university hospital between January and May 2023. The skin of the patients enrolled in the study was assessed for the presence of medical device-related pressure injuries, and all medical devices used were recorded. Data were collected using the Patient Identification Form, the Medical Device-Related Pressure Injury Follow-up Form, and the Braden Scale for Predicting Pressure Ulcer Risk.

RESULTS

It was found that 30.6% of the patients developed medical device-related pressure injuries; of these, 73.7% had stage I pressure injuries. We found that 36.8% of the patients were diagnosed with medical device-related pressure injuries within 8-11 days. The results showed that endotracheal tube (61.4%), non-invasive ventilation/oxygen mask (52.6%), Foley catheter (49.1%), and nasogastric tube (36.8%) devices were the most common causes of the development of medical device-related pressure injuries. Patients' demographic characteristics were found to have a significant effect on the development of medical device-related pressure injuries (p < .05).

CONCLUSION

The study found that the incidence of medical device-related pressure injuries was relatively high and that a relationship was observed between the patients' demographic characteristics and medical device-related pressure injuries. It is crucial that ICU nurses, who are more likely to encounter medical device-related pressure injuries, consider these factors when caring for their patients and take appropriate preventive measures to reduce the incidence of these injuries.

Examining the pediatric subglottic airway by ultrasound: A systematic review

OBJECTIVE

The purpose of this review was to determine the ability of ultrasound (US) to assess the subglottic airway in pediatric patients to estimate the appropriate size of endotracheal tube (ETT).

DATA SOURCES

Pubmed, Scopus, and Embase databases.

METHODS

A search of the literature was performed for studies that utilized ultrasonography to examine the minimal transverse diameter of the subglottic airway (MTDSA) in the pediatric (age < 18) population to estimate endotracheal tube (ETT) size. Articles were excluded if they involved adults or non-humans, had no comparison method, or were case reports. The primary outcome was the successful use of ultrasound compared to the reference standard defined by the study.

RESULTS

Sixteen studies were included, for a total of 1,633 pediatric subjects in whom transcervical laryngeal ultrasound was used prospectively to examine the MTDSA to estimate ETT size prior to intubation. Ultrasound reliably predicted the clinically best fit endotracheal tube by air leak test in 48-100% of subjects, while age-based formulas were accurate 24-95% of the time. Ultrasound was highly predictive of proper size, with R2 ranging between 0.684 to 0.980. Of those reintubated (n = 104), 86 (83%) required larger-sized tubes, while 18 (17%) required smaller-sized tubes. Both methods tended to underestimate ETT size, but the age-based formulas accounted for most of these differences.

CONCLUSION

Transcervical laryngeal ultrasound appears to be a reliable predictor of endotracheal tube size in children undergoing elective surgery, which has implications for preventing intubation-related trauma and ensuring adequate ventilation for those who may require prolonged intubation.
