Tracheostomy: Open Surgical or Percutaneous? An Effort to Solve the Continued Dilemma

Microbiological profiles of tracheostomy patients: a single-center experience

Background

This study compared the prevalence of common microorganisms in obstructed and non-obstructed cases across the four quarters on the first post-tracheostomy year.

Methods

A retrospective chart review of the microbiological profiles of all adult patients who underwent a tracheostomy was conducted between June 2015 and September 2019 at our hospital. Based on the tracheostomy indications, patients were allocated to obstructed or non-obstructed group. Any patient with at least one positive sample was followed up quarterly for a year. The first culture result obtained was recorded at least one month following the last antibiotic dose in each quarter.

Results

Out of the 65 tracheal aspirate results obtained from 58 patients (mean age, 57.5±16.48 years), the most common procedure and indications were surgical tracheostomy (72.4%) and non-obstructed causes (74.1%), respectively. Moreover, 47.7% of the culture results indicated Pseudomonas aeruginosa, which showed significantly different proportions across the quarters (p=0.006). Among obstructed patients, P. aeruginosa was the most common (35%), followed by methicillin-resistant Staphylococcus aureus (MRSA; 23.5%).

Conclusions

The most common post-tracheostomy microorganism was P. aeruginosa. MRSA showed a strong association with tracheostomy for obstructive indications.

A clinical retrospective study of percutaneous dilatational tracheostomy without guide wire for critically ill patients

OBJECTIVE

This study aimed to introduce a novel tracheostomy method, the non-guide-wire percutaneous dilatational tracheostomy (NGPDT) technique, and evaluate its effectiveness for critically ill patients undergoing neurosurgery under special conditions.

METHODS

The clinical data of 48 critically ill patients who underwent NGPDT under special conditions with controlled steps were analyzed retrospectively. The patients' demographic, preoperative state of illness, and diagnosis data were collected. Moreover, their intraoperative and postoperative variables were accessed, e.g., operation times, bleeding, saturation of pulse oxygen (SPO₂), and early and late complications related to NGPDT.

RESULTS

The mean patient age was 47.7 ± 13.7 years. The mean GCS (Glasgow Coma Scale) was 8.1 ± 2.9, and the mean BMI (Body Mass Index) was 25.2 ± 5.6. There were 38 patients with an endotracheal tube. The mean duration of onset to NGPDT was 4.0 ± 1.3 days. The mean operation time was 4.2 ± 1.9 min. There were 41 patients with mild intraoperative bleeding, 5 with moderate bleeding, and 2 with severe bleeding as well as 46 with mild postoperative bleeding and 2 with moderate bleeding. Additionally, 41 patients required complete extubation after NGPDT. The mean duration of incision healing was 4.8 ± 3.1 days. There was 1 patient with a decrease of SPO₂ ≥ 10%. Three patients presented with a transient violent cough at the primary tracheostomy stage; however, no patients suffered from pneumothorax, subcutaneous emphysema, false passage, or surgery-related death during this procedure.

CONCLUSION

Overall, NGPDT with controlled steps is a fast, safe, and microinvasive procedure. It mildly stimulates the trachea with a low rate of complications.

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.
