Updates in percutaneous tracheostomy and gastrostomy: should we strive for combined placement during one procedure?

PURPOSE OF REVIEW

Percutaneous tracheostomy and gastrostomy are minimally invasive procedures among the most common performed in intensive care units. Practices across centres vary considerably, and questions remain about the optimal timing, performance and postoperative care related to these procedures.

RECENT FINDINGS

The COVID-19 pandemic has triggered a reevaluation of the practice of percutaneous tracheostomy and gastrostomy in the ICU. Combined percutaneous tracheostomy and gastrostomy at the bedside has potential benefits, including improved nutrition, decreased exposure to anaesthetics, decreased patient transport and decreased hospital costs. Percutaneous ultrasound gastrostomy is a novel technique that eliminates the need for an endoscope that may allow intensivists to perform gastrostomy at the bedside.

SUMMARY

Multidisciplinary care is essential to the follow up of critically ill patients receiving tracheostomy and gastrostomy. Combined tracheostomy and gastrostomy has numerous potential benefits to patients and hospital systems. Interventional pulmonologists are uniquely qualified to perform both procedures and serve on a tracheostomy and gastrostomy team.

An overview of percutaneous endoscopic gastrostomy tube placement in the intensive care unit

Critically ill patients are at increased risk for malnutrition as they often have underlying acute and chronic illness, stress related catabolism, decreased appetite, trauma and ongoing inflammation. Malnutrition is recognized as a leading cause of adverse outcomes, higher mortality, and increased hospital costs. Percutaneous endoscopic gastrostomy (PEG) tubes provide a safe and effective route to provide supplemental enteral nutrition to these patients. PEG placement has essentially replaced surgical gastrostomy as the modality of choice for longer term feeding in patients. This is a highly prevalent procedure with 160,000 to 200,000 PEG procedures performed each year in the United States. The purpose of this review is to provide an overview of current knowledge and practice standards with regards to placement of PEG tube in the Intensive Care Unit (ICU). When a patient is considered for a PEG tube, it is important to evaluate the treatment alternatives and identify the best option for each patient. In this review, we provide the advantages and disadvantages of various feeding modalities and devices. We review the indications and contraindications for PEG tube placement as well as the risks of this procedure. We then describe in detail the per-oral pull, per-oral push, and direct percutaneous techniques for PEG tube placement. Additionally, we review the feasibility of having interventional pulmonologists place PEG tubes in the ICU.

Ultrasound use in the ICU for interventional pulmonology procedures

Critical care ultrasound has shifted the paradigm of thoracic imaging by enabling the treating physician to acquire and interpret images essential for clinical decision-making, at the bedside, in real-time. Once considered impossible, lung ultrasound based on interpretation of artifacts along with true images, has gained momentum during the last decade, as an integral part of rapid evaluation algorithms for acute respiratory failure, shock and cardiac arrest. Procedural ultrasound image guidance is a standard of care for both common bedside procedures, and advanced procedures within interventional pulmonologist’s (IP’s) scope of practice. From IP’s perspective, the lung, pleural, and chest wall ultrasound expertise is a prerequisite for mastery in pleural drainage techniques and transthoracic biopsies. Another ultrasound application of interest to the IP in the intensive care unit (ICU) setting is during percutaneous dilatational tracheostomy (PDT). As ICU demographics shift towards older and sicker patients, the indications for closed pleural drainage procedures, bedside transthoracic biopsies, and percutaneous dilatational tracheostomies have dramatically increased. Although ultrasound expertise is considered an essential IP operator skill there is no validated curriculum developed to address this component. Further, there is a need for developing an educational tool that matches up with the curriculum and could be integrated real-time with ultrasound-guided procedures.

Patient selection and preoperative evaluation of percutaneous dilation tracheostomy in the intensive care unit

Percutaneous dilation tracheostomy (PDT) is increasingly performed at the bedside of critically ill patients in the intensive care unit (ICU). PDT is safe overall and has a number of benefits compared to surgical tracheostomy. A tracheostomy tube has numerous advantages compared to an endotracheal tube, including decreased work of breathing, ease of connecting to a mechanical ventilator, improved patient comfort and pulmonary hygiene. Common patient populations include those unable to wean from mechanical ventilation, those requiring enhanced pulmonary hygiene, and those with progressive neuromuscular weakness. Clinicians performing this procedure should be familiar with common indications for performing tracheostomy as well as absolute and relative contraindications. Special patient populations, including those with morbid obesity, aberrant anatomic and vascular anatomy, cervical spine injury, and high ventilatory requirements, should be approached with careful planning. Pre-procedure evaluation for coagulopathy, including basic laboratory analysis and medication review, should be undertaken. Pre-procedure ultrasound may be used to more accurately identify landmarks and vascular structures. The optimal timing for performing PDT is unknown and depends on the unique characteristics of each patient, perceived natural history of the disease process being addressed and open conversations with the patient or surrogate decision maker. In this review, we identify patient populations most likely to benefit from PDT and outline data behind optimal timing, pre-procedural laboratory evaluation and patient specific factors that may influence procedural success.

Tracheostomy in Adult Intensive Care Unit: An ISCCM Expert Panel Practice Recommendations

BACKGROUND AND AIM

Critically ill patients on mechanical ventilation undergo tracheostomy to facilitate weaning. The practice in India may be different from the rest of the world and therefore, in order to understand this, ISCCM conducted a multicentric observational study "DIlatational percutaneous vs Surgical tracheoStomy in intEnsive Care uniT: A practice pattern observational multicenter study (DISSECT Study)" followed by an ISCCM Expert Panel committee meeting to formulate Practice recommendations pertinent to Indian ICUs.

MATERIALS AND METHODS

All existing International guidelines on the topic, various randomized controlled trials, meta-analysis, systematic reviews, retrospective studies were taken into account to formulate the guidelines. Wherever Indian data was not available, international data was analysed. A modified Grade system was followed for grading the recommendation.

RESULTS

After analyzing the entire available data, the recommendations were made by the grading system agreed by the Expert Panel. The recommendations took into account the indications and contraindications of tracheostomy; effect of timing of tracheostomy on incidence of ventilator associated pneumonia, ICU length of stay, ventilator free days & Mortality; comparison of surgical and percutaneous dilatational tracheostomy (PDT) in terms of incidence of complications and cost to the patient; Comparison of various techniques of PDT; Use of fiberoptic bronchoscope and ultrasound in PDT; experience of the operator and qualification; certain special conditions like coagulopathy and morbid obesity.

CONCLUSION

This document presents the first Indian recommendations on tracheostomy in adult critically ill patients based on the practices of the country. These guidelines are expected to improve the safety and extend the indications of tracheostomy in critically ill patients.

State of the Art: Interventional Pulmonology

Interventional pulmonology (IP) has evolved over the past decade from an obscure subspecialty in pulmonary medicine to a recognized discipline offering advanced consultative and procedural services to patients with thoracic malignancy, anatomic airway disease, and pleural disease. Innovative interventions are now also available for diseases not traditionally treated procedurally, such as asthma and emphysema. The IP field has established certification examinations and training standards for IP training programs in an effort to enhance training quality and ensure competency. Validating new technology and proving its cost-effectiveness and effect on patient outcomes present the biggest challenge to IP as the health-care environment marches toward value-based health care. High-quality research is now thriving in IP and promises to elevate its practice into patient-centric evidence-based care.

Interprofessional Care and Teamwork in the ICU

OBJECTIVES

We describe the importance of interprofessional care in modern critical care medicine. This review highlights the essential roles played by specific members of the interprofessional care team, including patients and family members, and discusses quality improvement initiatives that require interprofessional collaboration for success.

DATA SOURCES

Studies were identified through MEDLINE search using a variety of search phrases related to interprofessional care, critical care provider types, and quality improvement initiatives. Additional articles were identified through a review of the reference lists of identified articles.

STUDY SELECTION

Original articles, review articles, and systematic reviews were considered.

DATA EXTRACTION

Manuscripts were selected for inclusion based on expert opinion of well-designed or key studies and review articles.

DATA SYNTHESIS

"Interprofessional care" refers to care provided by a team of healthcare professionals with overlapping expertise and an appreciation for the unique contribution of other team members as partners in achieving a common goal. A robust body of data supports improvement in patient-level outcomes when care is provided by an interprofessional team. Critical care nurses, advanced practice providers, pharmacists, respiratory care practitioners, rehabilitation specialists, dieticians, social workers, case managers, spiritual care providers, intensivists, and nonintensivist physicians each provide unique expertise and perspectives to patient care, and therefore play an important role in a team that must address the diverse needs of patients and families in the ICU. Engaging patients and families as partners in their healthcare is also critical. Many important ICU quality improvement initiatives require an interprofessional approach, including Awakening and Breathing Coordination, Delirium, Early Exercise/Mobility, and Family Empowerment bundle implementation, interprofessional rounding practices, unit-based quality improvement initiatives, Patient and Family Advisory Councils, end-of-life care, coordinated sedation awakening and spontaneous breathing trials, intrahospital transport, and transitions of care.

CONCLUSIONS

A robust body of evidence supports an interprofessional approach as a key component in the provision of high-quality critical care to patients of increasing complexity and with increasingly diverse needs.

Assessment of the percutaneous dilatational tracheostomy technique in experimental manikins and canine cadavers

OBJECTIVE

To evaluate procedure time, ease of placement, and complication rates of percutaneous dilatational tracheostomy (PDT) compared to surgical tracheostomy (ST) in canine cadavers.

DESIGN

Randomized crossover experimental manikin and cadaver study involving 6 novice veterinary students.

SETTING

University teaching hospital.

ANIMALS

Canine tracheostomy training manikin, 24 canine cadavers.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

For training, each student performed 10 PDT and 10 ST procedures on a training manikin, followed by 2 PDT and 2 ST procedures on a canine cadaver. After each training procedure, feedback from bronchoscopy and observers was provided. Final PDT and ST tube placements using new equipment were performed in unused cadavers. Placements were timed, ease of placement was scored using visual analog scales (VAS, 0-10 cm), and complications were assessed by two independent observers using ordinal scales (0-3). Cadaver tracheas were explanted postprocedure to evaluate anatomical damage scores (0-3). Procedure time and VAS scores for PDT and ST procedures were analyzed using mixed-effects linear models, accounting for student, technique, and procedure number with post hoc pairwise comparisons. Data are presented as median (range). For the final cadaver placement, there were no significant differences in placement time (300 seconds [230-1020] vs 188 seconds [116-414], P = 0.210), ease of placement (3.8 cm [2.1-5.7] vs 1.9 cm [0-4.7], P = 0.132), anatomical damage score (1 [0-2] vs 0 [0-1], P = 0.063), or equipment complications score (0 [0-1] vs 0 [0-0], P = 1.000) between PDT and ST, respectively.

CONCLUSIONS

These data suggest that PDT can be performed as quickly, as easily, and as safely as ST in a canine cadaver by novice veterinary students following manikin training. Additional studies will be required to determine if these findings can be translated into veterinary clinical practice.

Otolaryngology consultation tracheostomies and complex patient population

PURPOSE

To assess for the differences in patients undergoing tracheostomy by the otolaryngology consult service versus other specialties.

MATERIALS AND METHODS

A series of 1035 tracheostomies performed at our institution from January 2013 through November 2015 was retrospectively reviewed. Patient-related factors that contribute to procedural difficulty were reviewed.

RESULTS

805 consecutive tracheostomies were included. Otolaryngology performed 176/805 (21.8%) tracheostomies as a consulting service. Morbidly obese patients were three times as likely to be referred to otolaryngology as other services (adjusted OR: 3.23; 95% CI: 2.21-4.72). Mean BMI was 36.38kg/m² for Consults vs. 28.69kg/m² for Others and morbidly obese patients had a mean BMI of 49.84kg/m² vs. 42.68kg/m² for Consults and Others respectively (p<0.001). Patients with upper airway compromise (8.5% of Consults vs. 1.6% for Others) had 5.5 times higher odds to be performed by otolaryngology (adjusted OR: 5.46; 95% CI: 2.24-13.28). Otolaryngology performed 81.8% of awake tracheostomies (n=9/11). There were significantly higher proportions of patients with diabetes, renal, pulmonary and cardiovascular disease in the Consults groups vs. Others (p<0.05).

CONCLUSIONS

More complex tracheostomies are being referred to and performed by otolaryngology at our institution. Difficult and challenging tracheostomies seem to be the "standard" for otolaryngologists.

Evidence-based guides in tracheostomy use in critical patients

OBJECTIVES

Provide evidence based guidelines for tracheostomy in critically ill adult patients and identify areas needing further research.

METHODS

A task force composed of representatives of 10 member countries of the Pan-American and Iberic Federation of Societies of Critical and Intensive Therapy Medicine and of the Latin American Critical Care Trial Investigators Network developed recommendations based on the Grading of Recommendations Assessment, Development and Evaluation system.

RESULTS

The group identified 23 relevant questions among 87 issues that were initially identified. In the initial search, 333 relevant publications were identified of which 226 publications were chosen. The task force generated a total of 19 recommendations: 10 positive (1B=3, 2C=3, 2D=4) and 9 negative (1B=8, 2C=1). A recommendation was not possible in six questions.

CONCLUSION

Percutaneous techniques are associated with a lower risk of infections compared to surgical tracheostomy. Early tracheostomy only seems to reduce the duration of ventilator use but not the incidence of pneumonia, the length of stay, or the long-term mortality rate. The evidence does not support the use of routine bronchoscopy guidance or laryngeal masks during the procedure. Finally, proper prior training is as important or even a more significant factor in reducing complications than the technique used.

Percutaneous Tracheostomy and Percutaneous Angiography: The Diuturnity of Sven-Ivar Seldinger of Mora, Pasquale Ciaglia of Utica

In the latter part of the 20th century, three developments intersected: skin-to-artery catheterization, percutaneous tracheostomy, and market introduction of video-chip camera-tipped endoscopes. By the millennium, every vessel within the body could be visualized radiographically, and percutaneous tracheostomy (with tracheal-ring "dilation," flawless high-resolution intratracheal video-imagery, and tracheal intubation) could consistently be achieved at the patient's bedside. Initiated through the skin and abetted by guide-wire insertion, these procedures are the lasting gifts of Sven-Ivar Seldinger (1921-1998) of Mora, Sweden, and Pasquale Ciaglia (1912-2000) of Utica, New York. Physicians and surgeons managing intracranial, craniofacial, and maxillofacial injury are among those honoring the Seldinger-Ciaglia "collaboration."

The Changing Role for Tracheostomy in Patients Requiring Mechanical Ventilation

Tracheostomy is performed in patients who require prolonged mechanical ventilation or have upper airway instability. Percutaneous tracheostomy with Ciaglia technique is commonly used and rivals the surgical approach. Percutaneous technique is associated with decreased risk of stomal inflammation, infection, and bleeding along with reduction in health resource utilization when performed at bedside. Bronchoscopy and ultrasound guidance improve the safety of percutaneous tracheostomy. Early tracheostomy decreases the need for sedation and intensive care unit stay but may be unnecessary in some patients who can be extubated later successfully. A multidisciplinary approach to tracheostomy care leads to improved outcomes.

Predicting the need for nonstandard tracheostomy tubes in critically ill patients

PURPOSE

Few guidelines exist regarding the selection of a particular type or size of tracheostomy tube. Although nonstandard tubes can be placed over the percutaneous kit dilator, clinicians often place standard tracheostomy tubes and change to nonstandard tubes only after problems arise. This practice risks early tracheostomy tube change, possible bleeding, or loss of the airway. We sought to identify predictors of nonstandard tracheostomy tubes.

MATERIALS AND METHODS

In this matched case-control study at an urban, academic, tertiary care medical center, we reviewed 1220 records of patients who received a tracheostomy. Seventy-seven patients received nonstandard tracheostomy tubes (cases), and 154 received standard tracheostomy tubes (controls).

RESULTS

Sex, endotracheal tube size, severity of illness, and computed tomography scan measurement of the distance from the trachea to the skin at the level of the superior aspect of the anterior clavicle were significant predictors of nonstandard tracheostomy tubes. Specifically, trachea-to-skin distance >4.4 cm and endotracheal tube sizes ≥8.0 were associated with nonstandard tracheostomy.

CONCLUSIONS

The findings suggest that clinicians should consider using nonstandard tracheostomy tubes as the first choice if the patient is male with an endotracheal tube size ≥8.0 and has a trachea-to-skin distance >4.4 cm on the computed tomography scan.

Developing a percutaneous dilatational tracheostomy service by medical intensivists: experience at one academic institution

PURPOSE

Percutaneous dilatational tracheostomy (PDT) is increasingly becoming the preferred method, compared with open surgical tracheostomy, for patients requiring chronic ventilatory assistance. Little is known regarding the process involved to incorporate PDT as a standard service in the medical intensive care unit. In this report, we describe our experience developing a "PDT service" led by medical intensivists.

MATERIALS AND METHODS

With support from our leadership and surgical colleagues, we developed a credentialing and training process for medical intensivists, formulated a bedside team to perform PDT, refined our technique, and maintained a patient data registry for quality improvement.

RESULTS

To date, our service includes 4 medical intensivists with PDT privileges. Over a 4-year period, we performed 171 PDTs for patients in the medical intensive care unit after 12.1 ± 8.2 days of mechanical ventilation. Our procedure-related complication rates are similar to other reports. No patient required emergent open surgical tracheostomy, and there were no deaths related to PDT. We required minimal to no backup support from our surgical colleagues in performing PDT.

CONCLUSIONS

We successfully developed a medical intensivist-driven PDT service, sharing our unique successes and challenges, to facilitate the care of our patients requiring prolonged ventilator support.

Interventional pulmonology procedures in the pediatric population

INTRODUCTION

Advanced training in interventional pulmonology (IP) includes a multidisciplinary approach to a wide variety of pathologic conditions affecting different age groups. The role of the interventional pulmonologist in the pediatric patient population has not been described. We report our experience of the care of pediatric patients by IP at an academic institution.

METHODS

A retrospective review of inpatient and outpatient IP procedures from 2008 to 2011 was performed. All patients' less than 21 years of age at the time of their procedure were identified. Data regarding age, procedure performed, pre-operative diagnosis, results, and complications were collected.

RESULTS

Thirty-five patients younger than the age of 21, with 14 of these patients being under the age of 18, were identified. Fifty-six procedures were performed on the entire cohort, 30 as inpatient procedures and 26 as outpatient procedures. There were no deaths or major complications related to any procedure.

DISCUSSION

We identified a cohort of pediatric patients that were able to successfully undergo diagnostic and therapeutic procedures under the direction of an experienced IP team. Cases included the evaluation and management of both malignant and benign complex airway and pleural diseases. There was no major morbidity or mortality related to our procedures, demonstrating an ability to safely evaluate and manage complex airway and pleural disease in the pediatric population.

Safety and feasibility of interventional pulmonologists performing bedside percutaneous endoscopic gastrostomy tube placement

BACKGROUND

Prior to the 1980s, permanent feeding tube placement was limited to an open surgical procedure until Gauderer and colleagues described the safe placement of percutaneous endoscopic gastrostomy (PEG) tubes. This procedure has since expanded beyond the realm of surgeons to include gastroenterologists, thoracic surgeons, and interventional radiologists. In some academic centers, interventional pulmonologists (IPs) also perform this procedure. We describe the safety and feasibility of PEG tube placement by IPs in a critically ill population.

METHODS

Prospectively collected data of patients in a medical ICU undergoing PEG tube placement from 2003 to 2007 at a tertiary-care center were reviewed. Inclusion criteria included all PEG tube insertions performed or attempted by the IP team. Data were collected on mortality, PEG tube removal rate, total number of days with PEG tube, and complication rates. Follow-up included hospital length of stay and phone contact after discharge. Procedural and long-term PEG-related complications were recorded.

RESULTS

Seventy-two patients were studied. PEG tube insertion was completed successfully in 70 (97.2%), with follow-up data in 69 of these 70. Thirty-day mortality was 11.7%. No deaths or immediate complications were attributed to PEG tube placement. PEG tube removal occurred in 27 patients, with a median time to removal of 76 days.

CONCLUSIONS

Bedside PEG tube placement can be performed safely and effectively by trained IPs. Because percutaneous tracheostomy is currently performed by IPs, the ability to place both PEG and tracheostomy tubes at the same time has the potential for decreased costs, anesthesia exposure, procedural times, ventilator times, and ICU days.

The business of interventional pulmonology

Interventional pulmonologists are regularly asked to perform more complicated and advanced procedures, but reimbursement for the time, effort and skill involved in these procedures has not kept up with other procedural specialties. Further changes in funding and reimbursement are likely under the Affordable Care Act. Understanding and effectively using the current system of funding for interventional pulmonology practices are imperative as we adapt to changing medical needs, legislative mandates, and reimbursement policy. This article reviews the current landscape of insurance and reimbursement in health care and anticipates some changes that might be expected from implementation of the Affordable Care Act.

Quality-of-life improvement and cost-effectiveness of interventional pulmonary procedures

Most interventional pulmonology studies focus on the technical success of procedures without measuring validated quality-of-life (QoL) outcomes. Studies are now incorporating end points that include QoL measurements and there are examples of interventional procedures that likely improve QoL. It is vital for the interventional pulmonary literature to incorporate cost-effectiveness when introducing new technology. While not uniformly analyzed in a rigorous manner in all studies, there are examples of interventional pulmonary studies that analyze cost-effectiveness through avoidance of more expensive procedures, cost savings per day free of emergency room visit, or cost savings per day not requiring intensive care unit care.

Percutaneous dilational tracheostomy

Tracheostomy is a commonly performed intervention with several benefits in the treatment of patients with chronic respiratory failure. Percutaneous dilational tracheostomy techniques have allowed bedside tracheostomy placement in the modern intensive care unit. Percutaneous dilational tracheostomy can be safely performed by interventional pulmonologists, medical intensive care physicians, and surgical specialists. When performed with the assistance of adjuncts, such as flexible bronchoscopy, the percutaneous dilational method has a favorable complication rate, efficiency, and cost profile compared with surgical tracheostomy.
