One thousand bedside percutaneous tracheostomies in the surgical intensive care unit: time to change the gold standard

Implementing a Bedside Percutaneous Tracheostomy and Ultrasound Gastrostomy Team Reduces Length of Stay and Hospital Costs Across Multiple Critical Care Units in a 1500 Bed Tertiary Care Center

BACKGROUND

Thousands of critically ill patients every year in the United States receive tracheostomy and gastrostomy procedures. Recent research has investigated the benefits of a combined team approach to these procedures, with associated decreases in length of stay (LOS) and hospital costs. This study's objective was to determine if implementing a bedside percutaneous tracheostomy and percutaneous ultrasound gastrostomy (PUG) team would reduce LOS and hospital costs. Design and Methods: This retrospective chart review compares the impact of implementing an ICU bedside percutaneous tracheostomy and PUG service team to the hospital's previous workflow (ie, pre-implementation). Inclusion criteria were adult patients with Ventilator Dependent Respiratory Failure (VDRF), a clinical indication for both procedures while admitted to the ICU and received both tracheostomy and gastrostomy procedures while admitted to the hospital. Pre- and post-implementation groups were compared across patients' demographics, clinical characteristics, and outcomes. ICU LOS, hospital LOS and total hospital costs were the primary outcome measures. Results: A total of 101 adult critically ill patients were included in the analysis; 49 patients were in the pre-implementation group and 52 patients in the post-implementation group (ie, PUG group). Patients in the PUG group had a significantly shorter mean ICU LOS and hospital LOS, 10.9- and 14.7-day reductions respectively (p = 0.010, p = 0.006). PUG group patients also had a significant reduction in total hospital costs, a per patient cost savings of $34 778 (p = 0.043). Conclusions: This study supports implementing a bedside percutaneous tracheostomy and PUG team to reduce LOS and total hospital costs in patients with VDRF.

Safety of percutaneous dilatational tracheostomy performed by intensivists versus surgeons: A retrospective cohort study

BACKGROUND

Percutaneous dilatational tracheostomy (PDT) is the preferred method for managing critically ill patients requiring prolonged mechanical ventilation. We aimed to compare the safety of PDT performed by intensivists versus surgeons.

METHODS

This retrospective, single center, cohort study included all the patients who underwent PDT from 2014 to 2023. Propensity score matching was performed to adjust the imbalances of covariates between the groups. The primary outcome was the occurrence of early complications after PDT. Secondary outcomes were the development of late complications of PDT and mortality directly related to tracheostomy.

RESULTS

1685 consecutive patients with critical illness were included in the analysis. Of these, 1396 (82.8%) PDTs were performed by surgeons and 289 (17.2%) by intensivists with background residency training in internal medicine. Early complications were reported in 80 (5.7%) of the patients in the surgeon group and in 13 (4.5%) patients in the intensivist group (p = 0.40). Minor hemorrhage was the most common early complication. Secondary outcomes were comparable in both groups. In a propensity score-matched cohort, the findings remained consistent.

CONCLUSIONS

This study suggests that PDT can be performed by intensivists, as well as surgeons, with the same safety profile. Our findings underscore the importance of incorporating PDT into the intensive care unit (ICU) training syllabus, ensuring the procedure is readily accessible with reliance on the expertise of ICU staff.

Impact of radiological surveillance for major blood vessels on complications of percutaneous dilatational tracheostomy: A retrospective cohort study

PURPOSE

Percutaneous dilatational tracheostomy (PDT) is the preferred method for managing long-term ventilator-dependent patients in ICUs. This study aimed to evaluate the association between preprocedural screening (ultrasound Doppler [USD] or computed tomography [CT]) for major neck blood vessels and complications in ICU patients undergoing PDT.

MATERIALS AND METHODS

This was a retrospective cohort study of patients who underwent PDT between 2012 and 2023 at a tertiary referral center. We performed a multivariable analysis and created a propensity-matched cohort. The primary outcome was bleeding within the first seven days after PDT. Secondary outcomes included early and late PDT complications and PTD-related mortality.

RESULTS

A total of 1766 consecutive critically ill patients hospitalized at a tertiary academic hospital were evaluated for PDT. Of these, 881 (49.9 %) underwent only physical examination before PDT, while 885 (50.1 %) underwent additional imaging (CT/USD). A higher proportion of patients in the imaging group were referred to open surgery due to suspected major blood vessels interfering with the procedure (6.2 % vs. 3.0 %, p = 0.001). Among the 1685 patients who underwent PDT, there was no significant difference in the rate of early bleeding between the physical examination group and the imaging group (4.6 % vs. 6.3 %, p = 0.12). Similarly, the overall early complication rates (5.5 % vs. 7.6 %, p = 0.08), late complication rates (1.6 % vs. 2.2 %, p = 0.42), and PDT-related mortality rates (0.7 % vs. 0.6 %, p = 0.73) did not exhibit significant differences between the two groups. In a propensity score-matched cohort, results remained consistent.

CONCLUSIONS

Physical examination can effectively identify major neck blood vessels without increasing the risk of bleeding during and after PDT.

Pro-Con Debate: Should Critically Ill Patients Undergo Procedures at Bedside or in the Operating Room?

Nonoperating room anesthesia (NORA) is a fast-growing field in anesthesiology, wherein anesthesia care is provided for surgical procedures performed outside the main operating room (OR) pavilion. Advances in medical science and technology have led to an increasing number of procedures being moved out of the operating room to procedural suites. One such NORA location is the intensive care unit (ICU), where a growing number of urgent and emergent procedures are being performed on medically unstable patients. ICU-NORA allows medical care to be provided to patients who are too sick to tolerate transport between the ICU and the OR. However, offering the same, high-quality, and safe care in this setting may be challenging. It requires special planning and a thorough consideration of the presence of life-threatening comorbidities and location-specific and ergonomic barriers. In this Pro-Con commentary article, we discuss these special considerations and argue in favor of and against routinely performing procedures at the bedside in the ICU versus in the OR.

Percutaneous dilatation tracheotomy in patients on extracorporeal membrane oxygenation after cardiac surgery

BACKGROUND

Current practices regarding percutaneous dilatational tracheostomy in adult patients treated with extracorporeal membrane oxygenation (ECMO) after cardiac surgery is not completely defined. This study aimed to evaluate the safety of the percutaneous dilatational tracheostomy in patients with ECMO after cardiac surgery.

METHODS

Between July 2017 and May 2021, 371 ECMO procedures were performed in more than 35,000 adult patients who underwent cardiac surgery in our hospital. Sixty-two patients underwent percutaneous dilatational tracheostomy (PDT) during or after ECMO. A retrospective analysis was performed comparing the incidence of complications and clinical outcomes of the two groups.

RESULTS

Of the 371 patients treated with ECMO after adult cardiac surgery during the enrollment period, 22 (7.1%) and 40 (12.8%) underwent PDT during or after ECMO, respectively. The platelet count (PLT) of the day was significantly lower in the PDT during ECMO group (54 (34, 68) vs. 108 (69, 162) (thousands), p < 0.001)). The prothrombin time (PT) and activated partial thromboplastin time (APTT) of the day were longer in the PDT during ECMO group (15.8 (14.6, 19.9) vs. 13.8 (13.2, 15.2) seconds, p = 0.001, 43.8 (38.0, 49.4) vs. 35.2 (28.2, 40.9) seconds, p < 0.001, respectively). There was no significant difference in tracheotomy-related complications between the two groups. Significantly decreased ventilator time was observed in the PDT during ECMO group.

CONCLUSIONS

Despite poor coagulation of the day, PDT during ECMO is safe and can appropriately reduce the duration of mechanical ventilation compared with PDT after ECMO weaning in adult patients who have undergone cardiac surgery.

Length of Stay and Hospital Cost Reductions After Implementing Bedside Percutaneous Ultrasound Gastrostomy (PUG) in a Critical Care Unit

Background: Critical care patients receive 50% of gastrostomy tubes placed in the United States. Several gastrostomy placement methods exist, however care processes remain variable and often lack health system cost effectiveness. No data exists on efficiency or cost impact of performing bedside percutaneous ultrasound gastrostomy (PUG) on patients with ventilator-dependent respiratory failure. This study's objective was to determine if implementing bedside PUG would positively impact efficiency and cost outcomes in intensive care unit (ICU) patients compared to usual care gastrostomy. Design and Methods: This is a retrospective cohort study of patients with ventilator-dependent respiratory failure who received a gastrostomy consult or procedure in the ICU. Patients received PUG or usual care gastrostomy, determined by the presiding attending's skillset, and both groups were compared across patients' demographics, clinical characteristics and outcomes. Primary outcomes were length of stay (LOS) and total hospital costs. Results: A total of 88 patients were included in the analysis, 45 patients in the PUG group and 43 in the usual care gastrostomy group. No differences were observed in demographic and clinical characteristics. Patients who received PUG had a significantly shorter mean ICULOS and hospital LOS, with reductions of 5.0 and 8.7 days, respectively. Total hospital costs were significantly reduced in the PUG group, with a cost savings of US $26,621 per patient. No differences in mortality or discharge disposition were observed. PUG patients received concomitant percutaneous dilatation tracheostomy (PDT) and PUG ("TPUG") 70% of the time, whereas no usual care patients received concomitant procedures. Off-hour procedures occurred in 53.3% of PUG and 4.6% of usual care gastrostomy. Conclusions: This study demonstrates bedside PUG leads to decreased LOS and total hospital costs in patients with ventilator-dependent respiratory failure. Hospital costs were significantly reduced with a per patient savings of $26,621 compared to usual care gastrostomy.

Safety of Prophylactic Anticoagulation During Bedside Procedures: A Prospective Multicenter Observational Study

BACKGROUND

Bedside percutaneous dilatational tracheostomy (PDT) and percutaneous endoscopic gastrostomy (PEG) are common procedures performed in the intensive care unit (ICU). Venous thromboembolism (VTE) prophylaxis is frequently prescribed to ICU patients and it remains unclear whether pre-procedure discontinuation is necessary.

METHODS

This multi-center prospective observational study aimed to describe bleeding rates in patients undergoing bedside PEG or PDT who did or did not have VTE prophylaxis held. Decision to hold prophylaxis was made by the operating physician. The primary endpoint was the rate of peri-procedural bleeding complications. Secondary endpoints included quantification of held doses in the peri-procedural period, rate of venous thromboembolism, and characteristics associated with having prophylaxis held.

RESULTS

91 patients were included over a 2-year period. Patients were on average aged 54 years, 40% female, mostly admitted to the trauma service (59%), and most commonly underwent bedside PDT (59%). Overall, 21% of patients had doses of pre-procedure prophylaxis held. Bleeding events occurred in 1 patient (1.4%) who had prophylaxis continued and in 1 patient (5.0%) who had prophylaxis held, a rate difference of 3.6% (95% CI-9.5%, 16.7%). One bleeding event was managed with bedside surgical repair and one with blood transfusion. There were 10 VTE events, all of whom had prophylaxis continued during the pre-procedure period but 3 had prophylaxis held after the procedure.

CONCLUSIONS

Bleeding complications were rare and did not significantly differ depending on whether prophylaxis was held or not. Future research is required to confirm the lack of risk with continuing prophylaxis through bedside procedures.

SARS-CoV-2 transmission risk to healthcare workers performing tracheostomies: a systematic review

BACKGROUND

Tracheostomy is a commonly performed procedure in patients with coronavirus disease 2019 (COVID-19) receiving mechanical ventilation (MV). This review aims to investigate the occurrence of SARS-CoV-2 transmission from patients to healthcare workers (HCWs) when tracheostomies are performed.

METHODS

This systematic review used the preferred reporting items for systematic reviews and meta-analysis framework. Studies reporting SARS-CoV-2 infection in HCWs involved in tracheostomy procedures were included.

RESULTS

Sixty-nine studies (between 01/11/2019 and 16/01/2022) reporting 3117 tracheostomy events were included, 45.9% (1430/3117) were performed surgically. The mean time from MV initiation to tracheostomy was 16.7 ± 7.9 days. Location of tracheostomy, personal protective equipment used, and anaesthesia technique varied between studies. The mean procedure duration was 14.1 ± 7.5 minutes; was statistically longer for percutaneous tracheostomies compared with surgical tracheostomies (mean duration 17.5 ± 7.0 versus 15.5 ± 5.6 minutes, p = 0.02). Across 5 out of 69 studies that reported 311 tracheostomies, 34 HCWs tested positive for SARS-CoV-2 and 23/34 (67.6%) were associated with percutaneous tracheostomies.

CONCLUSIONS

In this systematic review we found that SARS-CoV-2 transmission to HCWs performing or assisting with a tracheostomy procedure appeared to be low, with all reported transmissions occurring in 2020, prior to vaccinations and more recent strains of SARS-CoV-2. Transmissions may be higher with percutaneous tracheostomies. However, an accurate estimation of infection risk was not possible in the absence of the actual number of HCWs exposed to the risk during the procedure and the inability to control for multiple confounders related to variable timing, technique, and infection control practices.

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.

Retrospective analysis of open bedside tracheotomies in a German tertiary care university hospital

OBJECTIVE

Open surgical tracheotomy performed beside (STB) is a standardized procedure in critical ill patients. The aim of the study was to evaluate perioperative complications and the safety of STB in a tertiary care university hospital setting.

MATERIALS AND METHODS

Intra- and postoperative complications were retrospectively recorded and associations based on the evaluation of clinical and laboratory parameters were studied using regression analyses.

RESULTS

A total of 562 patients were included. Early tracheotomy shortened ventilation time after tracheotomy (ventilation before STB ≤ 5 days: mean 9.2 ± 9.1 days; ventilation before STB ≥ 6 days: mean 11.5 ± 10.5 days, p = 0.0001). Overall complications were found in 30/562 cases (5.3%), major complications in 12/562 cases (2.1%). Significant risk factors for overall tracheotomy related complications were higher body mass index (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.01-1.07, p = 0.02), lower CRP (OR 0.99, CI 0.99-1.00, p = 0.03), higher INR (OR 5.67, CI 1.27-25.34, p = 0.02), longer duration of operation (OR 1.03, CI 1.00-1.06, p = 0.04) and tracheotomy during extracorporeal membrane oxygenation (ECMO) support (OR 6.26, CI 1.21-32.44, p = 0.03).

CONCLUSION

STB represents a safe surgical procedure, also suitable for patients with an increased risk profile. Careful evaluation of individual risk factors should be favored to reduce procedure related complications.

Percutaneous dilatational tracheostomy in patients with mechanical circulatory support: Is the procedure safe?

Background

We aimed to investigate the efficacy and safety of percutaneous dilatational tracheostomy procedure following cardiac surgery in patients receiving extracorporeal membrane oxygenation and/or left ventricular assist device.

Methods

A total of 42 patients (10 males, 32 females; mean age 51±14.6 years; range, 18 to 77 years) who underwent percutaneous dilatational tracheostomy procedure under extracorporeal membrane oxygenation and/or left ventricular assist device support between January 2017 and January 2019 were retrospectively analyzed. Laboratory data, Simplified Acute Physiology Score-II and Sequential Organ Failure Assessment scores, and major and minor complications were recorded. The 30-day and one-year follow-up outcomes of the patients were reviewed.

Results

Of 42 patients, 17 (42.5%), 14 (33.3%), and 11 (26.2%) received left ventricular assist device, extracorporeal membrane oxygenation, and extracorporeal membrane oxygenation + left ventricular assist device, respectively. During percutaneous dilatational tracheostomy, the laboratory values of the patients were as follows: international normalized ratio, 2.3±0.9; partial thromboplastin time, 59.4±19.5 sec; platelet count, 139.2±65.8×109/L, hemoglobin, 8.8±1.0 g/dL, and creatinine, 1.6±1.0 mg/dL. No peri-procedural mortality, major complication, or bleeding was observed. We observed minor complications including localized stomal ooze in four patients (8.3%) and local stomal infection in three patients (6.2%).

Conclusion

Our study results suggest that percutaneous dilatational tracheostomy is an effective and safe technique in this patient population.

Tracheostomy for Coronavirus Disease 2019 Patients: Maintaining the Standard of Care

Objectives:

To respond to the new recommendations for delaying tracheostomy for coronavirus disease 2019 patients to day 21 post-intubation to ensure viral clearance.

Design:

Prospective observational cohort from April 1, 2020, to April 30, 2020, with 60 days follow-up.

Setting:

Academic medical center with nine adult ICUs dedicated to caring for coronavirus disease 2019 patients requiring mechanical ventilation.

Patients:

Mechanically ventilated patients with coronavirus disease 2019 pneumonia requiring tracheostomy for prolonged ventilatory support.

Interventions:

Adherence to the standard of care for timing of tracheostomy as deemed necessary by the intensivist without delay and utilizing the existing tracheostomy team in performing the needed procedures within 1 day of the request.

Measurements and Main Results:

One hundred eleven patients with coronavirus disease 2019 received tracheostomy in the month of April 2020. Median time to tracheostomy was 11 days. All procedures were performed percutaneously at bedside under bronchoscopic guidance. Sixty-three percent of patients who received tracheostomy either weaned or discharged alive within 60 days of the procedure. Performing tracheostomy on these patients without delay did not lead to coronavirus disease 2019 viral transmission to the tracheostomy team as evident by lack of symptoms and negative antibody testing.

Conclusions:

Adherence to standard of care in timing of tracheostomy is safe. Recommending delaying the procedure may lead to harmful consequences from prolonging mechanical ventilation and sedation without apparent benefit.

From the ICU to the operating room: how to manage the patient?

PURPOSE OF REVIEW

To outline key points for perioperative ICU optimization of nutrition, airway management, blood product preparation and transfusion, antibiotic prophylaxis and transport.

RECENT FINDINGS

Optimization entails glycemic control for all, with specific attention to type-1 diabetic patients. Transport-related adverse events may be averted with surgery in the ICU. If moving the patient is unavoidable, transport guidelines should be followed and hemodynamic optimization, airway control, and stabilization of mechanical ventilation ensured before transport. Preinduction preparation includes assessment of the airway and the provision of high-flow oxygen to prolong apneic oxygenation. Postintubation, a protective positive ventilation strategy should be employed. Ideal transfusion thresholds are 7 g/dl for hemodynamically stable adult patients, 8 g/dl in orthopedic or cardiac surgery patients as well as those with underlying cardiovascular disease. Higher transfusions thresholds may be required in specific disease states. Antimicrobial prophylaxis within 120 min of incision prevents most surgical site infections. Antibiotic therapy depends on the antibiotics being received in the ICU, the time elapsed since ICU admission, local epidemiology and the type of surgery. Tailored antimicrobial regimens may be continued periprocedurally. If more than 70% of the nutritional requirement cannot be met enterally, parenteral nutrition should be initiated within 5-7 days of surgery or earlier if the patient is malnourished.

SUMMARY

ICU patients who require surgery may benefit from appropriate perioperative management.

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.

Is tracheotomy on the decline in otolaryngology? A single institutional analysis

OBJECTIVE

A recent study reported decreasing trends in tracheotomy procedures by its otolaryngology service. We set out to determine whether the previously reported decrease in otolaryngology performed tracheotomies by one institution is a local or generalizable phenomenon.

DESIGN

Retrospective cohort study from 2010 to 2015.

SETTING

Tertiary care hospital and affiliated regional hospitals.

SUBJECT AND METHODS

All patients who received tracheotomy during the period of analysis were included. Performing specialty, surgical technique, and procedure location were recorded. Procedures were stratified by year and specialty to generate incidence rate ratios for otolaryngologists and non-otolaryngologists. Incidence rate ratios were estimated with negative binomial regression across services.

RESULTS

The otolaryngology service demonstrated a yearly decrease of 3.4% in the total number of tracheotomies (95% CI -7.9% to +1.4, P=0.17). While the thoracic service remained constant (+0.3%, 95% CI -2.6% to +3.3%, p=0.83), general surgery demonstrated the greatest increase in procedures (+4.4%, 95% CI -6.0% to +15.8%, P=0.42). Thoracic and general surgery both dramatically increased the number of percutaneous tracheotomies performed, with general surgery also performing a greater number of bedside procedures.

CONCLUSIONS AND RELEVANCE

We observed a similar decline in the number of tracheotomies otolaryngology over six years. Our trend is likely due to changes in consultations patterns, increasing use of the percutaneous method, and an increase in adjunctive gastrostomy tube placements. Investigations on the impact of a greater number of non-otolaryngology performed tracheotomies on follow up care is warranted.

Ultrasound-Guided Percutaneous Dilational Tracheostomy: A Systematic Review of Randomized Controlled Trials and Meta-Analysis

INTRODUCTION

Percutaneous dilational tracheostomy (PDT) is a common and increasingly used procedure in the intensive care unit (ICU). It is usually performed with bronchoscopy guidance. Ultrasound has emerged as a useful tool in order to assist PDT, potentially improving its success rate and reducing procedural-related complications.

OBJECTIVE

To investigate whether the ultrasound-guided PDT is equivalent or superior to the bronchoscopy-guided or anatomical landmarks-guided PDT with regard to procedural-related and clinical complications.

METHODS

A systematic review of randomized clinical trials was conducted comparing an ultrasound-guided PDT to the control groups (either a bronchoscopy-guided PDT or an anatomical landmark-guided PDT) in patients undergoing a PDT in the ICU. The primary outcome was the incidence of major procedural-related and clinical complication rates. The secondary outcome was the incidence of minor complication rates. Random-effect meta-analyzes were used to pool the results.

RESULTS

Four studies fulfilled the inclusion criteria and they were analyzed. The studies included 588 participants. There were no differences in the major complication rates between the patients who were assigned to the ultrasound-guided PDT when compared to the control groups (pooled risk ratio [RR]: 0.48; 95% confidence interval [CI]: 0.13-1.71, I² = 0%). The minor complication rates were not different between the groups, but they had a high heterogeneity (pooled RR: 0.49; 95% CI 0.16-1.50; I² = 85%). The sensitivity analyzes that only included the randomized controlled trials that used a landmark-guided PDT as the control group showed lower rates of minor complications in the ultrasound-guided PDT group (pooled RR: 0.55; 95% CI: 0.31-0.98, I² = 0%).

CONCLUSION

The ultrasound-guided PDT seems to be safe and it is comparable to the bronchoscopy-guided PDT regarding the major and minor procedural-related or clinical complications. It also seems to reduce the minor complications when compared to the anatomical landmark-guided PDT.

Bedside Percutaneous Dilatational Tracheostomy by Griggs Technique: A Single-Center Experience

Background

The study evaluated reliability and outcomes of percutaneous dilatational tracheostomy (PDT) performed via Griggs’ method in the intensive care unit.

Material/Methods

We examined 78 patients who underwent bedside PDT in the intensive care unit (ICU). Demographic characteristics were recorded. In addition, ventilator-related pneumonia, duration of performing PDT, and rates of complications, mortality, and morbidity were assessed.

Results

The mean age of patients was 68.7 years, and 56.4% were females (n=44). The most common indication for ICU was pneumonia (44.9%, n=35), followed by trauma (24.8%, n=13). Mean opening of PDT was 21 minutes. Mean duration of intubation prior to PDT was 21±6 days. Mean FiO₂ before and after PDT was 58.7% and 49.1%, respectively. PEEP ratios before and after PDT were 5 and 3, respectively. Seventy-one patients (91%) needed no sedation after PDT. Mechanical ventilator-induced pneumonia was observed in 32.1% (n=25) of patients. The overall complication rate after PDT was 37.1%, most of which were minor. The most common and early complication of PDT was bleeding (28.2%, n=22). Other minor complications included hypotension (3.8%, n=3), desaturation (3.8%, n=3), and subcutaneous emphysema (1.3%, n=1).

Conclusions

Tracheostomy offers advantages in terms of improving patient comfort, facilitating weaning of patients from the respirator, and providing clearance of pulmonary secretions by reducing pulmonary dead-spaces. PDT is a simple and reliable procedure with lower complication rates. Its advantages include implementation at bedside, with a shortened procedure duration and accelerated wound healing.

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.

Safety of Percutaneous Dilatational Tracheostomy in Patients with Acute Brain Injury and Reduced PaO2/FiO2 Ratio-Retrospective Analysis of 54 Patients

OBJECTIVE

Percutaneous dilatational tracheostomy (PDT) is a commonly performed method in neurocritical care, and its safety has been proven in numerous studies. Nevertheless, data regarding the application in patients with acute brain injury and poor respiratory function are poor. The purpose of this study was to evaluate the incidence of hypoxemia and hypercapnia during PDT in those patients.

METHODS

In a retrospective analysis, we acquired data from 54 patients with an acute brain injury (ABI) and a reduced PaO₂/FiO₂ ratio (PaO₂/FiO₂ < 300 mm Hg). In all cases, blood gas analyses before, during, and approximately 12 hours after PDT were available. We reviewed the patients' ventilator settings, results of gas exchange, and radiographic signs of acute respiratory distress syndrome (ARDS). Patients with ARDS were defined using the Berlin criteria.

RESULTS

We observed 2 cases (3.6%) of intraoperative hypoxemia (PaO₂ < 60 mm Hg) and 4 cases (7.4%) of intraoperative hypercapnia (PaCO₂ > 55 mm Hg). Twenty patients fulfilled the Berlin criteria for ARDS. While mean PaO₂ did not differ significantly between ARDS and non-ARDS patients, intraoperative hypoxemia only occurred in the ARDS group (2/20). Mean PaCO₂ was similar in the ARDS and non-ARDS groups, and cases of hypercapnia were apparent in both groups. The mean PaO₂/FiO₂ ratio of all patients improved from 229.1 mm Hg before PDT to 255.3 mm Hg.

CONCLUSIONS

Regarding the intraoperative gas exchange, indication of PDT in patients with ABI and ARDS should be considered carefully. However, PDT in ABI patients with reduced PaO₂/FiO₂ ratio alone appears to be a safe procedure.

Fiber optic bronchoscopy-assisted percutaneous tracheostomy: a decade of experience at a university hospital

Objective

To evaluate the efficacy and safety of percutaneous tracheostomy by means of single-step dilation with fiber optic bronchoscopy assistance in critical care patients under mechanical ventilation.

Methods

Between the years 2004 and 2014, 512 patients with indication of tracheostomy according to clinical criteria, were prospectively and consecutively included in our study. One-third of them were high-risk patients. Demographic variables, APACHE II score, and days on mechanical ventilation prior to percutaneous tracheostomy were recorded. The efficacy of the procedure was evaluated according to an execution success rate and based on the necessity of switching to an open surgical technique. Safety was evaluated according to post-operative and operative complication rates.

Results

The mean age of the group was 64 ± 18 years (203 women and 309 males). The mean APACHE II score was 21 ± 3. Patients remained an average of 11 ± 3 days on mechanical ventilation before percutaneous tracheostomy was performed. All procedures were successfully completed without the need to switch to an open surgical technique. Eighteen patients (3.5%) presented procedure complications. Five patients experienced transient desaturation, 4 presented low blood pressure related to sedation, and 9 presented minor bleeding, but none required a transfusion. No serious complications or deaths associated with the procedure were recorded. Eleven patients (2.1%) presented post-operative complications. Seven presented minor and transitory bleeding of the percutaneous tracheostomy stoma, 2 suffered displacement of the tracheostomy cannula, and 2 developed a superficial infection of the stoma.

Conclusion

Percutaneous tracheostomy using the single-step dilation technique with fiber optic bronchoscopy assistance seems to be effective and safe in critically ill patients under mechanical ventilation when performed by experienced intensive care specialists using a standardized procedure.

Early Versus Late Tracheostomy for Patients with High and Low Cervical Spinal Cord Injuries

OBJECTIVES

This study aimed to evaluate the effects of early versus late tracheostomies among patients with cervical spinal cord injuries (CSCIs).

METHODS

This retrospective study included 69 adult CSCI patients who underwent bedside percutaneous tracheostomies at the Intensive Care Unit of Khoula Hospital, Muscat, Oman, between January 2011 and October 2015. The tracheostomy was considered early if the procedure took place within one week of the CSCI. The impact of an early tracheostomy on patient outcomes was analysed in terms of duration of mechanical ventilation and intensive care unit (ICU) stay among patients with high (C1-C2 vertebrae) and low (C3-C7 vertebrae) CSCIs. Ventilator dependence, bradycardia episodes and surgical intervention outcomes were also examined.

RESULTS

Patients with a high CSCI who underwent an early tracheostomy spent significantly fewer days on mechanical ventilation compared to those who underwent a late tracheostomy (9.3 ± 7.2 days versus 13.7 ± 3.2 days; P = 0.041). Low CSCI patients who received an early tracheostomy also experienced significantly fewer days on mechanical ventilation compared to those undergoing a late tracheostomy (12.1 ± 10.4 days versus 25.2 ± 17.7 days; P = 0.035). Moreover, ICU mortality was significantly lower for high CSCI patients who underwent an early tracheostomy (P = 0.015). However, there was no association between length of ICU stay and either type of CSCI or timing of the tracheostomy procedure.

CONCLUSION

An early tracheostomy is beneficial in reducing the duration of mechanical ventilation among patients with CSCIs, irrespective of the level of injury.

Prospective study of percutaneous tracheostomy: Role of bronchoscopy and surgical technique

Objective:

Percutaneous tracheostomy is a common procedure but varies considerably in approach. The aim of our study was to evaluate the need for intraoperative bronchoscopy and to compare various surgical techniques.

Methods:

During 1 year all percutaneous tracheostomies in three intensive care units were prospectively documented according to a unified protocol. In one unit, bronchoscopy was used routinely and in others only during the study.

Results:

A total of 111 subjects (77 males) with median age 64 (range, 18–86) years and body mass index 25.4 (range, 15.9–50.7) were included. In unit A, tracheal wall was directly exposed; in unit B, limited dissection to enable tracheal palpation was made. In both units, bronchoscopy was used to check the location of an already inserted guiding needle; needle position required correction in 8% and 12% of cases, respectively. In unit C, in tracheostomies without pretracheal tissue dissection, bronchoscopy was used to guide needle insertion; needle position required correction in 66% of cases. Median duration of operations performed by thoracic surgeons and residents was 10 (range, 3–37) min and by intensive care doctors and residents was 16.5 (range, 3–63) min (p < 0.001). Time from the beginning of preparations for tracheostomy until the end of the whole procedure was median 32 min for bedside tracheostomies and 64 min for operations in the operating theatre (p < 0.001).

Conclusion:

Limited pretracheal tissue dissection enabled proper guiding needle insertion and bronchoscopy was rarely needed. Percutaneous tracheostomies performed by thoracic surgeons took less time, and duration of the whole procedure was remarkably shorter when performed at bedside.

Prognostic indicators for early mortality after tracheostomy in the intensive care unit

BACKGROUND

Tracheostomy is indicated for patients requiring prolonged mechanical ventilation. The aim of this study is to identify prognostic indicators for early mortality after tracheostomy to potentially avoid futility in the intensive care unit.

METHODS

Patients who underwent tracheostomy and died within 30 d of admission (futile group) were compared with patients who underwent tracheostomy and survived more than 30 d after admission (nonfutile group). Categorical data were analyzed using chi-square and Fisher's exact tests. Continuous variables were analyzed using T-tests and Mann-Whitney U tests. Prognostic factors were evaluated with univariable and multivariable logistic regression analyses.

RESULTS

Overall, 88.3% of patients underwent nonfutile tracheostomy, while 11.7% underwent futile tracheostomy. Serum albumin level (1.5 g/dL versus 1.9 g/dL, P = 0.040) and mechanical ventilation duration before procedure (10 versus 12 d, P = 0.029) were significantly less in the futile group. Hypoalbuminemia (<2 g/dL) and preoperative mechanical ventilation ≤10 d were also predictive of futile tracheostomy in multivariable analysis.

CONCLUSIONS

Hypoalbuminemia may serve as a prognostic indicator and risk factor for early mortality after tracheostomy. In patients with hypoalbuminemia, treatment of underlying disease processes and trending serum albumin level recovery in response to treatment may provide some insight to clinicians with regard to timing of tracheostomy. Better prognostic tools are still needed for critically ill patients to avoid futility in the intensive care unit. In this cohort, 88.3% of patients undergoing tracheostomy survived past 30 d.

Percutaneous techniques versus surgical techniques for tracheostomy

BACKGROUND

Tracheostomy formation is one of the most commonly performed surgical procedures in critically ill intensive care participants requiring long-term mechanical ventilation. Both surgical tracheostomies (STs) and percutaneous tracheostomies (PTs) are used in current surgical practice; but until now, the optimal method of performing tracheostomies in critically ill participants remains unclear.

OBJECTIVES

We evaluated the effectiveness and safety of percutaneous techniques compared to surgical techniques commonly used for elective tracheostomy in critically ill participants (adults and children) to assess whether there was a difference in complication rates between the procedures. We also assessed whether the effect varied between different groups of participants or settings (intensive care unit (ICU), operating room), different levels of operator experience, different percutaneous techniques, or whether the percutaneous techniques were carried out with or without bronchoscopic guidance.

SEARCH METHODS

We searched the following electronic databases: CENTRAL, MEDLINE, EMBASE, and CINAHL to 28 May 2015. We also searched reference lists of articles, 'grey literature', and dissertations. We handsearched intensive care and anaesthesia journals, abstracts, and proceedings of scientific meetings. We attempted to identify unpublished or ongoing studies by contacting manufacturers and experts in the field, and searching in trial registers.

SELECTION CRITERIA

We included randomized and quasi-randomized controlled trials (quasi-RCTs) comparing percutaneous techniques (experimental intervention) with surgical techniques (control intervention) used for elective tracheostomy in critically ill participants (adults and children).

DATA COLLECTION AND ANALYSIS

Three authors independently checked eligibility and extracted data on methodological quality, participant characteristics, intervention details, settings, and outcomes of interest using a standardized form. We then entered data into Review Manager 5, with a double-entry procedure.

MAIN RESULTS

Of 785 identified citations, 20 trials from 1990 to 2011 enrolling 1652 participants fulfilled the inclusion criteria. We judged most of the trials to be at low or unclear risk of bias across the six domains, and we judged four studies to have elements of high risk of bias; we did not classify any studies at overall low risk of bias. The quality of evidence was low for five of the seven outcomes (very low N = 1, moderate N = 1) and there was heterogeneity among the studies. There was a variety of adult participants and the procedures were performed by a wide range of differently experienced operators in different situations.There was no evidence of a difference in the rate of the primary outcomes: mortality directly related to the procedure (Peto odds ratio (POR) 0.52, 95% confidence interval (CI) 0.10 to 2.60, I² = 44%, P = 0.42, 4 studies, 257 participants, low quality evidence); and serious, life-threatening adverse events - intraoperatively: risk ratio (RR) 0.93, 95% CI 0.57 to 1.53, I² = 27%, P = 0.78, 12 studies, 1211 participants, low quality evidence,and direct postoperatively: RR 0.72, 95% CI 0.41 to 1.25, I² = 24%, P = 0.24, 10 studies, 984 participants, low quality evidence.PTs significantly reduce the rate of the secondary outcome, wound infection/stomatitis by 76% (RR 0.24, 95% CI 0.15 to 0.37, I² = 0%, P < 0.00001, 12 studies, 936 participants, moderate quality evidence) and the rate of unfavourable scarring by 75% (RR 0.25, 95% CI 0.07 to 0.91, I² = 86%, P = 0.04, 6 studies, 789 participants, low quality evidence). There was no evidence of a difference in the rate of the secondary outcomes, major bleeding (RR 0.70, 95% CI 0.45 to 1.09, I² = 47%, P = 0.12, 10 studies, 984 participants, very low quality evidence) and tracheostomy tube occlusion/obstruction, accidental decannulation, difficult tube change (RR 1.36, 95% CI 0.65 to 2.82, I² = 22%, P = 0.42, 6 studies, 538 participants, low quality evidence).

AUTHORS' CONCLUSIONS

When compared to STs, PTs significantly reduce the rate of wound infection/stomatitis (moderate quality evidence) and the rate of unfavourable scarring (low quality evidence due to imprecision and heterogeneity). In terms of mortality and the rate of serious adverse events, there was low quality evidence that non-significant positive effects exist for PTs. In terms of the rate of major bleeding, there was very low quality evidence that non-significant positive effects exist for PTs.However, because several groups of participants were excluded from the included studies, the number of participants in the included studies was limited, long-term outcomes were not evaluated, and data on participant-relevant outcomes were either sparse or not available for each study, the results of this meta-analysis are limited and cannot be applied to all critically ill adults.

Inadvertent migration of guidewire into Murphy's eye of endotracheal tube during percutaneous dilatational tracheostomy

Percutaneous dilatational tracheostomy is a commonly performed bedside procedure in the Intensive Care Unit. Although serious and fatal complications have been reported, the procedure is by and large safe to perform in experienced hands. We report here an innocuous problem encountered twice. After the guidewire insertion and dilatation, subsequent railroading became difficult owing to migration of guidewire into the Murphy's eye of the endotracheal tube (ETT). Awareness about this possibility can avert inadvertent delays and complications during the procedure. A tug or gentle pulling of ETT after insertion of the guidewire rules out an impaction in the eye or other part of the ETT.

Technical Improvements of Difficult Tracheotomy

The aim of this study was to explore the application value of technical improvements of difficult tracheotomy. Percutaneous dilatational tracheotomy kit combined with traditional surgical tracheotomy was performed on seven patients with various types of difficult tracheotomy surgery from Jan. 2011 to Mar. 2013 in our hospital. The indicators, such as difficulty degree and intraoperative peripheral oxygen saturation changes of each patient, were assessed and analyzed. The average operating time was 20 min (from the beginning of skin incision to the implantation of the tracheal tube), and the time from cutting out tracheal cartilage rings to completely implanting tracheal tube was with 2 min; the intraoperative oxygen saturation degrees were all above 92 %. There were no serious complications, such as intraoperative hemorrhea, asphyxia, cardiac arrest, or others, and no complications, such as postoperative bleeding, pneumothorax, cervical spinal cord injury, tracheal stenosis, tracheoesophageal fistula, or others, appeared. The technical improvements used in difficult tracheotomy could reduce the risk of surgery, difficulties of the surgical operation and postoperative complications and make the operation much more easy and more suitable for the clinical application.

The role of cricothyrotomy, tracheostomy, and percutaneous tracheostomy in airway management

Cricothyrotomy, percutaneous dilation tracheostomy, and surgical tracheostomy are cost-effective and safe techniques employed in the management of critically ill patients requiring insertion of an artificial airway. These procedures have been well characterized and studied in the surgical, emergency medicine, and critical care literature. This article focuses on the role of each of these modalities in airway management, specifically comparing the data for each procedure in regard to procedural outcomes. The authors discuss the techniques available and the relevant background data regarding choice of each method and its integration into clinical practice.

Anesthetic Implications for Tracheal Injury During Bronchoscopy-Guided Percutaneous Dilational Tracheostomy

Bronchoscopic-guided percutaneous dilational tracheostomy has become one of the most common elective tracheostomy methods for patients requiring prolonged ventilatory support. The safety profile, patient selection, and risks as well as complication management, when compared with an open surgical technique, remain somewhat controversial with no clear recommendations. We present a case of a critically ill patient undergoing percutaneous dilation tracheostomy complicated by tracheal wall injury and airway loss. The airway was successfully conservatively managed as well as the tracheal injury. Anesthetic implications, safety, and management options as well as recommendations are reviewed.

A Prospective Randomized Study Comparing Mini-surgical Percutaneous Dilatational Tracheostomy With Surgical and Classical Percutaneous Tracheostomy: A New Method Beyond Contraindications

Although percutaneous dilatational tracheostomy (PDT) is more accessible and less time-demanding compared with surgical tracheostomy (ST), it has its own limitations. We introduced a modified PDT technique and brought some surgical knowledge to the bedside to overcome some standard percutaneous dilatational tracheostomy relative contraindications. PDT uses a blind route of tracheal access that usually requires perioperational imaging guidance to protect accidental injuries. Moreover, there are contraindications in certain cases, limiting widespread PDT application. Different PDT modifications and devices have been represented to address the problem; however, these approaches are not generally popular among professionals due to limited accessibility and/or other reasons.We prospectively analyzed the double-blinded trial, patient and nurse head evaluating the complications, and collected data from 360 patients who underwent PDT, ST, or our modified mini-surgical PDT (msPDT, Hashemian method). These patients were divided into 2 groups-contraindicated to PDT-and randomization was done for msPDT or PDT in PDT-indicated group and msPDT or ST for PDT-contraindicated patients. The cases were compared in terms of pre and postoperational complications.Data analysis demonstrated that the mean value of procedural time was significantly lower in the msPDT group, either compared with the standard PDT or the ST group. Paratracheal insertion, intraprocedural hypoxemia, and bleeding were also significantly lower in the msPDT group compared with the standard PDT group. Other complications were not significantly different between msPDT and ST patients.The introduced msPDT represented a semiopen incision, other than blinded PDT route of tracheal access that allowed proceduralist to withdraw bronchoscopy and reduced the total time of procedure. Interestingly, the most important improvement was performing msPDT on PDT-contraindicated patients with the complication rate comparable to surgical procedure.

A modified technique for percutaneous dilatational tracheostomy: A retrospective review of 60 cases

BACKGROUND

We describe a modified technique for percutaneous dilatational tracheostomy (PDT) using intermittent bronchoscopy and ultrasound (US). This method requires 1 single physician operator and no special airway adjuncts. Our aim is to reduce the complications associated with the current popular PDT technique, that is, accidental intraprocedural airway loss, intraprocedural bleeding, and hypoventilation associated with use of continuous bronchoscopy.

STUDY DESIGN

This is a retrospective review of all PDTs performed on intensive care unit patients at a single nonacademic hospital by a pulmonologist using the modified PDT technique.

RESULTS

Sixty consecutive PDT procedures were performed using the modified technique. Forty-five percent of the patients were considered high-risk individuals for PDT. There were no deaths from the modified PDT procedure. There were no major complications including accidental extubation, major bleeding, posterior tracheal wall laceration, pneumothorax, hemodynamic instability, severe hypoxemia, or infection. The failure rate of PDT was 1.6%. There was no puncture of the bronchoscope, endotracheal tube, or endotracheal tube balloon. All procedures were performed by 1 single physician operator.

CONCLUSION

Our modified technique demonstrates a potential to reduce accidental intraprocedural airway loss and intraoperative bleeding associated with PDT while possibly improving gas exchange and saving procedural costs. This technique needs to be comparatively studied with current popular PDT technique in a prospective trial to firmly establish associated risks and benefits.

Safe tracheostomy: blunt puncture and dilation after minimal surgical exposure of the trachea (BPAD tracheostomy)

A number of complications can occur following both surgical tracheostomy (ST) and percutaneous tracheostomy (PT). A flexible new tracheostomy insertion technique with the advantages of both ST and PT is proposed to reduce these complications. Our blunt puncture and dilation technique (BPAD tracheostomy) appears to be technically safe and feasible to perform.

Dilation balloon rupture during percutaneous dilational tracheostomy: using Blue Dolphin kit

A 72-year-old man presented to the high dependency unit following an elective incisional hernia repair. He was extubated in the immediate postoperative period. Following established type 2 respiratory failure (secondary to hospital-acquired pneumonia), he required tracheal intubation and was ventilated in the intensive care unit (ICU). He failed extubation and subsequently had a percutaneous single-stage dilational tracheostomy fitted as indicated. During the tracheostomy, while inflating the dilation balloon (used to dilate the trachea), the balloon burst in the trachea, at a pressure of 3 atmospheres. Following this, the entire dilating unit and tracheostomy tube were removed; no debris was left inside the trachea as confirmed by bronchoscope (used throughout the procedure). He made good recovery and was discharged to a surgical ward. This case report summarises the indications for tracheostomy, and reports the rare event of balloon rupture and how to manage it within the ICU setting.

Griggs percutaneous tracheostomy without bronchoscopic guidance is a safe method: A case series of 300 patients in a tertiary care Intensive Care Unit

Introduction:

Percutaneous tracheostomy (PCT) is being increasingly done by intensivists for critical care unit patients requiring either prolonged ventilation and/or for airway protection.[1] Bronchoscopic guidance considered a gold standard,[23] is not always possible due to logistic reasons and ventilation issues. We share our experience of Griggs PCT technique without bronchoscopic guidance with simple modifications to ensure safe execution of the procedure.

Objective:

The purpose of this study was to evaluate the safety issues and complications of PCT without bronchoscopic guidance in a multi-disciplinary tertiary Intensive Care Unit (ICU).

Materials and Methods:

A retrospective review of consecutive PCTs performed in our ICU between August 2010 and December 2013 by Griggs guide wire dilating forceps technique without bronchoscopic guidance is being presented. It is done by withdrawing endotracheal tube with inflated cuff while monitoring expired tidal volume on ventilator and ensuring the free mobility of guide wire during each step of the procedure, thereby ensuring a safe placement of the tracheostomy tube (TT) in trachea.

Results:

Analysis of 300 PCTs showed 26 patients (8.6%) had complications including 2 (0.6%) patients deteriorated neurologically and 2 (0.6%) deaths observed within 24 h following procedure. The median operating time was 3.5 min (range, 2.5–8 min). There were no TT placement problems in any case.

Conclusion:

Percutaneous tracheostomy can be safely performed without bronchoscopic guidance by adhering to simple steps as described.

Predictors of the necessity for early tracheostomy in patients with acute cervical spinal cord injury: a 15-year experience

BACKGROUND

The need for mechanical ventilation (MV) after spinal cord injury (SCI) is a risk factor for prolonged critical care. The "purpose" of this study was to identify the level of cervical SCI that requires MV, thereby defining candidates for tracheostomy.

METHODS

Patients with cervical SCI over a 15-year period were reviewed.

RESULTS

One hundred sixty-three patients sustained cervical SCI. Of 76 complete injuries, 91% required MV for greater than 48 hours. By injury level, MV incidence was 100% for C2-4, 91% for C5, 79% for C6, and 80% for C7. Only one quarter of patients with incomplete SCI required MV for greater than 48 hours; Glascow Coma Score and Injury Severity Score were significantly worse compared with patients not requiring MV.

CONCLUSIONS

Factors influencing the decision for tracheostomy in cervical SCI patients include the presence of a complete SCI, anatomic level of injury, Glascow Coma Score, Injury Severity Score, and associated thoracic injury. Patients with complete cervical SCI often require prolonged MV. Conversely, the minority of incomplete SCI required MV; the need for tracheostomy was likely performed for associated injuries. Utilizing identified factors permits a thoughtful approach to tracheostomy in this patient population.

Comparison between ultrasound- and bronchoscopy-guided percutaneous dilational tracheostomy in critically ill patients: a retrospective cohort study

INTRODUCTION

Percutaneous dilational tracheostomy (PDT) is routinely performed in the intensive care unit with bronchoscopic guidance. Recently, ultrasound (US) has emerged as a new safety adjunct tool to increase the efficacy of PDT. However, the available data are limited to case series without any control group. Hence, a retrospective cohort study was designed to evaluate the efficacy of US-guided PDT compared with bronchoscopy-guided PDT.

METHODS

All patients who were submitted to PDT after the standardization of US-guided PDT technique in our institution were analyzed. Demographic and procedure-related variables, complications, and clinical outcomes were collected and compared in patients undergoing US- or bronchoscopy-guided PDT.

RESULTS

Sixty patients who had been submitted to PDT were studied, including 11 under bronchoscopy guidance and 49 under US guidance. No surgical conversion was necessary in any of the procedures, and bronchoscopy assistance was only required in 1 case in the US group. The procedure length was shorter in the US group than in the bronchoscopy group (12 vs 15 minutes, P = .028). None of the patients had any major complications. The minor complication rates were not significantly different between the groups, nor was the probability of breathing without assistance within 28 days, intensive care unit length of stay, or hospital mortality.

CONCLUSION

Ultrasound-guided PDT is effective, safe, and associated with similar complication rates and clinical outcomes compared with bronchoscopy-guided PDT.

Early tracheostomy improves outcomes in severely injured children and adolescents

BACKGROUND

Early tracheostomy has been advocated for adult trauma patients to improve outcomes and resource utilization. We hypothesized that timing of tracheostomy for severely injured children would similarly impact outcomes.

METHODS

Injured children undergoing tracheostomy over a 10-year period (2002-2012) were reviewed. Early tracheostomy was defined as post-injury day ≤ 7. Data were compared using Student's t test, Pearson chi-squared test and Fisher exact test. Statistical significance was set at p<0.05 with 95% confidence intervals.

RESULTS

During the 10-year study period, 91 patients underwent tracheostomy following injury. Twenty-nine (32%) patients were < 12 years old; of these, 38% received early tracheostomy. Sixty-two (68%) patients were age 13 to 18; of these, 52% underwent early tracheostomy. Patients undergoing early tracheostomy had fewer ventilator days (p=0.003), ICU days (p=0.003), hospital days (p=0.046), and tracheal complications (p=0.03) compared to late tracheostomy. There was no difference in pneumonia (p=0.48) between early and late tracheostomy.

CONCLUSION

Children undergoing early tracheostomy had improved outcomes compared to those who underwent late tracheostomy. Early tracheostomy should be considered for the severely injured child.

SUMMARY

Early tracheostomy is advocated for adult trauma patients to improve patient comfort and resource utilization. In a review of 91 pediatric trauma patients undergoing tracheostomy, those undergoing tracheostomy on post-injury day ≤ 7 had fewer ventilator days, ICU days, hospital days, and tracheal complications compared to those undergoing tracheostomy after post-injury day 7.

[Percutaneous tracheostomy through dilatation with the Ciaglia Blue Dolphin(®) method]

OBJECTIVE

To describe the perioperative and postoperative complications in critically ill patients requiring percutaneous tracheostomy using the Ciaglia Blue Dolphin(®) technique.

DESIGN

A prospective, observational, cohort study was carried out.

SCOPE

Two medical-surgical Intensive Care Units.

PATIENTS

Adult patients subjected to prolonged mechanical ventilation.

INTERVENTION

Percutaneous tracheostomy using Ciaglia Blue Dolphin(®) with an endoscopic guide.

VARIABLES

Demographic variables, intraoperative and postoperative complications, and Intensive Care Unit and ward mortality were recorded.

RESULTS

Seventy patients were included. Age: 68.6 ± 12 years (68.6% males). APACHE II score: 23.5±8.7. Duration of mechanical ventilation prior to percutaneous tracheostomy: 14.3 ± 5.5 days. Perioperative complications were recorded in 25 patients. In 23 of them the complications were mild: difficulty inserting the tracheostomy cannula (n=10), mild bleeding (n=7), partial atelectasis (n=3), cuff leak (n=2), and technical inability to complete the procedure (switch to Ciaglia Blue Rhino(®)) (n=1). Severe complications were recorded in 2 patients: severe bleeding that forced completion of the procedure via surgical tracheostomy (n=1), and false passage with desaturation (n=1). None of the complications proved life-threatening. Eleven complications occurred in the learning curve. As postoperative complications, mild peri-cannula bleeding was seen in 2 patients.

CONCLUSIONS

Percutaneous tracheostomy using the Ciaglia Blue Dolphin(®) technique with an endoscopic guide is a safe procedure. As with other procedures, the learning curve contributes to increase the incidence of complications. Potential benefits versus other percutaneous tracheostomy techniques should be explored by randomized trials.

Evolution of percutaneous dilatational tracheostomy--a review of current techniques and their pitfalls

Tracheostomy is the most commonly performed surgical procedure in critically ill patients with acute respiratory failure. While few absolute indications exist, this procedure is widely used in patients with upper respiratory obstruction and those requiring long-term mechanical ventilation. The traditional approach to tracheostomy has been an open procedure performed in the operating room. This method is associated with an increased rate of complications and costs. Accordingly, percutaneous bedside tracheostomy procedures have largely replaced the traditional operative approach at many institutions. Numerous methods for percutaneous tracheostomy have thus emerged. However, the benefits of one technique versus another have not been well demonstrated. In this article, we review the evidence supporting the use of percutaneous tracheostomy procedures over the traditional operative approach. Furthermore, we review the currently available and emerging methods by which percutaneous tracheostomy can be performed. In addition, we highlight the available evidence concerning the safety and complication rates of each technique.
