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

Trends for Percutaneous Tracheostomy in Italian Acute Care Setting over a 5-Year Period

Background: Tracheostomy is a widespread procedure usually performed with a percutaneous approach for prolonged mechanical ventilation. Little is known about the population-based trends for percutaneous tracheostomies (PT). The aim of this study was to evaluate the order to analyze the characteristics, rates, and costs of PTs performed in Italy from 2009 to 2014. Methods: We analyzed 102,646 PTs performed in Italy between 2009 and 2014. We obtained the data of patients from the section of the discharge report of the Italian Ministry of Health (National Archive for Hospital Discharge Form, Ministry of Health) about age, gender, length of stay (LOS), hospital types, and hospital region for code 541 and 542 for the years 2009, 2010, 2011, 2012, 2013 and 2014. Our additional source of data was the Annual Discharge Reports of the Italian Ministry of Health. Results: In this study, including 102,646 PTs performed from 2009 to 2014, we found that (1) the rates of PTs significantly decreased over time; (2) PTs were mostly performed in patients aged less than 65 years and hospitalized in ICUs for less than 40 days; and (3) the costs of PTs severely decreased over time, with a breakpoint between 2011 and 2012. Conclusions: Percutaneous tracheostomy is still a procedure frequently performed in the setting of acute care. Although percutaneous tracheostomy still results in high medical care reimbursement, it is a safe and cost-saving procedure.

A safer and more practical tracheotomy in invasive mechanical ventilated patients with COVID-19: A quality improvement study

IMPORTANCE

The number of infections and deaths caused by the global epidemic of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) invasion is steadily increasing daily. In the early stages of outbreak, approximately 15%-20% of patients with coronavirus disease 2019 (COVID-19) inevitably developed severe and critically ill forms of the disease, especially elderly patients and those with several or serious comorbidities. These more severe forms of disease mainly manifest as dyspnea, reduced blood oxygen saturation, severe pneumonia, acute respiratory distress syndrome (ARDS), thus requiring prolonged advanced respiratory support, including high-flow nasal cannula (HFNC), non-invasive mechanical ventilation (NIMV), and invasive mechanical ventilation (IMV).

OBJECTIVE

This study aimed to propose a safer and more practical tracheotomy in invasive mechanical ventilated patients with COVID-19.

DESIGN

This is a single center quality improvement study.

PARTICIPANTS

Tracheotomy is a necessary and important step in airway management for COVID-19 patients with prolonged endotracheal intubation, IMV, failed extubation, and ventilator dependence. Standardized third-level protection measures and bulky personal protective equipment (PPE) may hugely impede the implementation of tracheotomy, especially when determining the optimal pre-surgical positioning for COVID-19 patients with ambiguous surface position, obesity, short neck or limited neck extension, due to vision impairment, reduced tactile sensation and motility associated with PPE. Consequently, the aim of this study was to propose a safer and more practical tracheotomy, namely percutaneous dilated tracheotomy (PDT) with delayed endotracheal intubation withdrawal under the guidance of bedside ultrasonography without the conventional use of flexible fiberoptic bronchoscopy (FFB), which can accurately determine the optimal pre-surgical positioning, as well as avoid intraoperative damage of the posterior tracheal wall and prevent the occurrence of tracheoesophageal fistula (TEF).

Fiber-optic Bronchoscope-guided vs Mini-surgical Technique of Percutaneous Dilatational Tracheostomy in Intensive Care Units

Background

Percutaneous dilatational tracheostomy (PCDT) using fiber-optic bronchoscope (FOB) is a widely practiced technique, but its availability and cost remain a concern in nations with limited resources. Mini-surgical technique of PCDT incorporating minimal blunt dissection has shown improved results even without the use of FOB. The study is primarily intended to compare these two techniques and establish a safer cost-effective alternative to FOB-guided PCDTs.

Patients and methods

This randomized comparative study [registered (CTRI/2018/04/013191)] was conducted on 120 mechanically ventilated patients. In 60 patients, mini-surgical PCDT (group-M) was performed with 2 cm longitudinal skin incision and blunt dissection till pretracheal fascia without FOB guidance using Portex-Ultraperc^™ sets. In remaining 60 patients, PCDT was performed under FOB vision with similar skin incision (without blunt dissection) using Portex-Ultraperc^™ sets (group-F). Two techniques were compared with regard to procedural time and percentage of complications occurred during or after the procedure.

Results

Procedure time [group-M: 6.30 ± 1.28 minutes; group-F: 14.43 ± 1.84 minutes (p <0.001)] and mean blood loss [group-M: 5.33 ± 1.69 mL; group-F: 6.87 ± 3.11 mL (p = 0.001)] was significantly less in group-M. Higher incidence of desaturation [group-M: 16.7%; group-F: 35% (p = 0.022)] was noted in group-F, whereas arrhythmias [group-M: 21.7%; group-F: 6.7% (p = 0.018)] were higher in group-M. There was no statistical difference in incidence of pneumothorax and subcutaneous emphysema. There was no incidence of posterior tracheal wall perforation in any of the patients.

Conclusion

Mini-surgical technique is a faster alternative of FOB-guided PCDT with comparable incidence of complications. It can safely be used in intensive care units (ICUs) where FOB is not available.

Beneficial Outcomes of Early Tracheostomy in Patients Requiring Prolonged Mechanical Ventilation

BACKGROUND

Considering that tracheostomy is being done for huge amount of critically ill patients, the ideal time for this procedure is still controversial among different intensive care units (ICU).

MATERIALS AND METHODS

70 intubated patients were included in our study which was sorted into two subgroups: half of our patients received an early tracheostomy (ET) within 1-10 days post intubation and the rest received late tracheostomy (LT) within 11-21 days after getting intubated.

RESULTS

61.9% of the study population was male and the mean age was of 54 + 10.5 years. ET group mean Mechanical Ventilation (MV) duration was 8.11±4.9 days and was 16.3 ± 6.01 in the LT group (p<0.05) with a mean sedation duration of 6.1 ± 4.4 vs. 12.0 ± 6.5 (ET vs. LT) (p<0.05). Mean time of weaning process from ventilator was 2.7 ±2.3 for ET group and 5.5 ± 5.0 for LT group (p<0.05). The Mean ICU stay was 18.8 ± 2.2 in the ET group, and 22.1 ± 4.1 in the LT group (p: 0.98) at the same time. Length of stay at hospital for two group of patients did not show a meaningful difference (p= 0.279).

CONCLUSION

Early tracheostomy decreases duration of mechanical ventilation and sedation use and more rapid weaning process in those patients who will require mechanical ventilation. Our findings revealed that tracheostomy timing has no significant impact on rate of hospital mortality and LOS at ICU and hospital.

Validation of Calprotectin As a Novel Biomarker For The Diagnosis of Pleural Effusion: a Multicentre Trial

Discriminating between malignant pleural effusion (MPE) and benign pleural effusion (BPE) remains difficult. Thus, novel and efficient biomarkers are required for the diagnosis of pleural effusion (PE). The aim of this study was to validate calprotectin as a diagnostic biomarker of PE in clinical settings. A total of 425 patients were recruited, and the pleural fluid samples collected had BPE in 223 cases (53.7%) or MPE in 137 patients (33%). The samples were all analysed following the same previously validated clinical laboratory protocols and methodology. Calprotectin levels ranged from 772.48 to 3,163.8 ng/mL (median: 1,939 ng/mL) in MPE, and 3,216-24,000 ng/mL in BPE (median: 9,209 ng/mL; p < 0.01), with an area under the curve of 0.848 [95% CI: 0.810-0.886]. For a cut-off value of ≤ 6,233.2 ng/mL, we found 96% sensitivity and 60% specificity, with a negative and positive predictive value, and negative and positive likelihood ratios of 96%, 57%, 0.06, and 2.4, respectively. Multivariate analysis showed that low calprotectin levels was a better discriminator of PE than any other variable [OR 28.76 (p < 0.0001)]. Our results confirm that calprotectin is a new and useful diagnostic biomarker in patients with PE of uncertain aetiology which has potential applications in clinical practice because it may be a good complement to cytological methods.

Performing Percutaneous Dilational Tracheostomy without using Fiberoptic Bronchoscope

BACKGROUND

Percutaneous tracheostomy is an elective method that is increasingly being taken up in the intensive care unit alongside the patient's bed. In many centers, bronchoscopy is used, but the necessity of using bronchoscopy in percutaneous tracheostomy has not yet been determined. Discontinuing use of bronchoscopy can potentially reduce the cost and increase the efficiency of percutaneous tracheostomy. Therefore, in this study, we performed a percutaneous dilatational tracheostomy without using fiberoptic bronchoscopy.

MATERIALS AND METHODS

This study was performed as a descriptive epidemiological survey among 70 patients in Shahid Rajaei Hospital of Qazvin in 2015 and 2016. The results were assessed in the patients.

RESULTS

In this study, pneumothorax, trauma, major and minor bleeding, cuff leak and change to surgical procedures as well as accidental extubation were not seen. However, subcutaneous emphysema, mal-position and hypoxia each were seen in one patient (1.4%).

CONCLUSION

Totally the results demonstrated that percutaneous dilatation tracheostomy without fiberoptic bronchoscopic guidance is useful and safe.

Prevalence of Tracheostomy and Its Indications in Iran: A Systematic Review and Meta-Analysis

BACKGROUND

Tracheostomy is common among intensive care unit (ICU) patients. Reconsideration of tracheostomy indications in patients can be effective in modifying and reducing irrevocable patient complaints. The present study aimed to analyze the prevalence of tracheostomy indications and to estimate the prevalence of tracheostomy in Iran.

MATERIALS AND METHODS

In this systematic review and meta-analysis, scientific databases were searched from January 1990 to April 2018. The inclusion criteria were as follows: 1) use of the term "tracheotomy" in the title; and 2) studies conducted in Iran. On the other hand, the exclusion criteria were: 1) studies that did not specify the type of mechanical ventilation; 2) studies that did not quantitatively report the indications; 3) studies without access to the full-text; and 4) case studies, letters to the editor, and/or prefaces. Data were extracted from published reports. Our preliminary results included estimations of tracheostomy indications in Iran.

RESULTS

In the preliminary search, a total of 325 articles were found, 24 of which were considered eligible. Among 2860 patients who had undergone tracheostomy, 21 indications were identified. Decreased mental status, respiratory disease, and tumors were the most frequent indications. The prevalence of tracheostomy was 40.59% in Iran, with the highest and lowest rates reported in Birjand and Ardabil, respectively (136.50 and 6.63 in 100,000 people, respectively) based on the random effects model.

CONCLUSION

The most prevalent indications in Iran are different from those reported in other countries. This difference may be due to the lack of trained medical personnel and available technologies.

Ultrasound-guided percutaneous dilatational tracheostomy using a saline-filled endotracheal tube cuff as an ultrasonographic puncture target: A feasibility study

PURPOSE

The saline-filled endotracheal tube (ETT) cuff can be easily identified under cervical ultrasound and can serve as an ideal puncture target during percutaneous dilatational tracheostomy (PDT). The authors present their initial experience with this novel technique.

MATERIALS AND METHODS

The records of 38 consecutive critically ill patients who underwent saline-filled cuff puncture PDT between October 2016 and December 2017 were retrospectively reviewed. The saline-filled ETT cuff was easily identified using ultrasound. Ultrasound-guided puncture into the cuff, followed by an inward-push of the ETT through the tube exchanger, facilitated accurate passage of the guidewire through the needle tip into the tracheal lumen.

RESULTS

Of 38 consecutive procedures, 37 (97.4%) were performed successfully, with only one converted to surgical tracheostomy due to guidewire displacement. The median procedure time was 8 min. There were no complications, such as accidental extubation, major bleeding, or posterior tracheal wall laceration or pneumothorax, and no procedure-related mortalities.

CONCLUSIONS

PDT performed using a saline-filled cuff as the ultrasound-guided puncture target and an endotracheal tube exchanger is feasible, and appeared to be easier to perform than standard PDT. Larger studies are required to confirm the safety and benefits of this technique.

Investigating PIK3R3 and ATp2A1 Genes Expressions in Ventilator-Associated Pneumonia Patients Admitted to the Intensive Care Unit of Masih Daneshvari Hospital in 2016

BACKGROUND

Infectious diseases such as ventilator- associated pneumonia (VAP) are one of the serious problems in intensive care units (ICU) of hospitals. To date, there has been no appropriate clinical and diagnostic marker for early detection of this disease. In this study, expression of PIK₃R₃ and ATp₂A₁ genes in patients with VAP were assessed to be used as biomarkers to identify and confirm the disease.

METHODS

This study was conducted by using peripheral blood samples of 60 individuals, including 30 patients with VAP and 30 healthy volunteers. First, the peripheral blood samples were taken and then RNA was extracted and converted into cDNA. Finally, the assessment of genes was performed by Real-time PCR.

RESULTS

In peripheral blood samples, 46.6% and 30% were positive for PIK₃R₃ expression in patients and healthy groups, respectively. The ATp₂A₁ expression in patients and healthy controls were found 40% and 23.3%, respectively. Comparing the ΔCT obtained for the PIK₃R₃ and ATp₂A₁ genes showed statistically significant differences between the two groups of patients and healthy subjects (p=0.042, p=0.036).

CONCLUSION

ATp₂A₁ and PIK₃R₃ may be used as biomarkers for early detection of VAP disease. However, further studies are required.

Tracheotomy in the intensive care unit: Guidelines from a French expert panel: The French Intensive Care Society and the French Society of Anaesthesia and Intensive Care Medicine

Tracheotomy is widely used in intensive care units, albeit with great disparities between medical teams in terms of frequency and modality. Indications and techniques are, however, associated with variable levels of evidence based on inhomogeneous or even contradictory literature. Our aim was to conduct a systematic analysis of the published data in order to provide guidelines. We present herein recommendations for the use of tracheotomy in adult critically ill patients developed using the grading of recommendations assessment, development and evaluation (GRADE) method. These guidelines were conducted by a group of experts from the French Intensive Care Society (Société de réanimation de langue française) and the French Society of Anesthesia and Intensive Care Medicine (Société francaise d'anesthésie réanimation) with the participation of the French Emergency Medicine Association (Société française de médecine d'urgence), the French Society of Otorhinolaryngology. Sixteen experts and two coordinators agreed to consider questions concerning tracheotomy and its practical implementation. Five topics were defined: indications and contraindications for tracheotomy in intensive care, tracheotomy techniques in intensive care, modalities of tracheotomy in intensive care, management of patients undergoing tracheotomy in intensive care, and decannulation in intensive care. The summary made by the experts and the application of GRADE methodology led to the drawing up of 8 formal guidelines, 10 recommendations, and 3 treatment protocols. Among the 8 formal guidelines, 2 have a high level of proof (Grade 1±) and 6 a low level of proof (Grade 2±). For the 10 recommendations, GRADE methodology was not applicable and instead 10 expert opinions were produced.

Safety of Surgical Tracheostomy during Extracorporeal Membrane Oxygenation

Background

The risk of bleeding during extracorporeal membrane oxygenation (ECMO) is a potential deterrent in performing tracheostomy at many centers. To evaluate the safety of surgical tracheostomy (ST) in critically ill patients supported by ECMO, we reviewed the clinical correlation between preoperative coagulation status and bleeding complication-related ST during ECMO.

Methods

From April 1, 2012 to March 31, 2016, ST was performed on 38 patients supported by ECMO. We retrospectively reviewed and analyzed the medical records including complications related to ST.

Results

Heparin was administered to 23 patients (60.5%) for anticoagulation during ECMO, but 15 patients (39.5%) underwent ECMO without anticoagulation. Of the 23 patients administered anticoagulation therapy, heparin infusion was briefly paused in 13 prior to ST. The median platelet count, international normalized ratio, and activated partial thromboplastin time before ST were 126 × 10⁹/L (range, 46 to 434 × 10⁹/L), 1.2 (range, 1 to 2.3) and 62 seconds (27 to 114.2 seconds), respectively. No peri-procedural clotting complications related to ECMO were observed. Two patients (5.3%) suffering from ST-related major bleeding required surgical hemostasis. Minor bleeding after ST occurred in two cases (5.3%). No significant difference was found according to anticoagulation management (P = 0.723). No fatality was attributable to ST.

Conclusions

The complication rates of ST in the patients supported by ECMO were low. Therefore, ST performed by an experienced operator, and with careful optimization of coagulation status, is a relatively safe procedure; the use of ST with ECMO should thus not be dismissed on account of the potential for bleeding caused by the administration of anticoagulants.
