For decades, the standard technique for tracheostomy was the open, surgical technique. However, during the past 20 years, the use of percutaneous dilatational tracheostomy has been increased and shown to be a feasible and safe procedure in critically ill patients. The purpose of this report is to review the percutaneous dilatational tracheostomy technique, describe the role of bronchoscopy as guidance for the procedure, and identify the available evidences comparing percutaneous dilatational tracheostomy to surgical tracheostomy.

Percutaneous dilatational tracheostomy (PDT) has become an increasingly popular method of establishing an airway for patients in need of chronic ventilator assistance. We report a rare case of a 42-year-old female who developed extensive subcutaneous emphysema, bilateral pneumothoraces, pneumomediastinum, and pneumoperitoneum after percutaneous dilatational tracheostomy. The patient suffered from amyotrophic lateral sclerosis, and underwent PDT after a period of mechanical ventilation. During PDT, tracheostomy tube was inserted into the paratracheal space. Follow-up chest radiography and computed tomography of chest and abdomen revealed extensive subcutaneous emphysema, bilateral pneumothoraces, pneumomediastinum, and pneumoperitoneum. The patient was treated successfully with insertion of the thoracostomy tube and conservative care.

A 68-year-old man presented with a posterior tracheal wall injury caused by percutaneous dilatational tracheostomy. The wound was immediately covered with an absorbable polyglycolic acid sheet. Ten days after the injury, the perforation was closed with knotless sutures using a Castroviejo needle-holder through the tracheostomy. The successful repair in this case indicates the feasibility of the knotless suture technique for perforations. The technique is described in detail in this report. The patient was weaned from the mechanical ventilator on postoperative day 25. In cases of posterior tracheal posterior wall perforation, every effort should be made to repair the perforation through an existing opening.

연구배경 : 외과적 기관절개술(surgical tracheostomy, ST)은 수술장에서 외과의에 의해 시행되며 중환자의 경우 수술장으로 이동은 위험을 수반하고, 또한 수술장과 외과의가 확보되지 않아 적기에 시행되지 못하는 경우도 흔하다. ST에 대한 대안으로 최근 경피적 확장 기관절개술(percutaneous dilational tracheostomy, PDT)이 구미에서 많이 시행되고 있으나 국내에서는 아직 보편화되지 않아 PDT의 시술 용이성 및 합병증을 ST와 비교해 보고자 하였다. 방 법 : 7일 이상 기계 환기 중이거나 인공 기도 확보가 요구되는 중환자 38명을 대상으로 ST(n=18) 또는 PDT(n=20)를 시행하였다. PDT군에 비해 ST군의 여성 비가 높은 것 외에 양 군 간에 임상적 특성은 차이가 없었다. ST군은 이비인후과 전공의에 의해, PDT군은 내과 전공의 또는 호흡기내과의에 의해 각각 기관절개술이 시행되었다. PDT는 기관지경 보조하에 Ciaglia Percutaneous Tracheostomy Set(Cook Critical Care, Bloomington, USA)를 사용하였다. 양 군에서 시술 의사 미확보 등으로 당일 기관절개술이 이루어지지 못한 건수, 기관절개술 시술 소요 시간 및 기관절개술과 관련된 합병증 발생율 등을 비교하였다. 결 과 : 기관절개술이 결정된 후 당일 시행되지 못한 예는 ST군에서 11예(61%), PDT군에서는 3예(15%)였다(P<0.05). 시술 소요 시간은 ST군 $29.1{\pm}11.6$ 분, PDT군 $15.6{\pm}7.1$ 분이었다(P<0.0001). 기관절개술의 합병증은 ST군에서 T-cannula의 우발적 발관 l예, 피하기종 2예, 소량 출혈 2예, PDT군에서 기관내 관의 조기 발관 1예, 소량 출혈 2예 및 피하기종 1예가 발생하였다(P>0.05). 결 론 : PDT는 중환자에서 수술장 이동이나 외과의 확보의 필요 없이 즉시 시행할 수 있고, 술기 습득이 용이하며 합병증은 ST와 비교하여 차이가 없었다.

Background: A significant proportion of cardiac surgery intensive care unit (CSICU) patients require long-term ventilation, necessitating tracheostomy placement. The goal of this study was to evaluate the long-term postoperative outcomes and complications associated with percutaneous dilatational tracheostomy (PDT) in CSICU patients. Methods: All patients undergoing PDT after cardiac, thoracic, or vascular operations in the CSICU between January 1, 2013 and January 1, 2021 were identified. They were evaluated for mortality, decannulation time, and complications including bleeding, infection, and need for surgical intervention. Multivariable regression models were used to identify predictors of early decannulation and the complication rate. Results: Ninety-three patients were identified for this study (70 [75.3%] male and 23 [24.7%] female). Furthermore, 18.3% of patients had chronic obstructive pulmonary disease (COPD), 21.5% had history of stroke, 7.5% had end-stage renal disease, 33.3% had diabetes, and 59.1% were current smokers. The mean time from PDT to decannulation was 39 days. Roughly one-fifth (20.4%) of patients were on dual antiplatelet therapy and 81.7% had anticoagulation restarted 8 hours post-tracheostomy. Eight complications were noted, including 5 instances of bleeding requiring packing and 1 case of mediastinitis. There were no significant predictors of decannulation prior to discharge. Only COPD was identified as a negative predictor of decannulation at any point in time (hazard ratio, 0.28; 95% confidence interval, 0.08-0.95; p=0.04). Conclusion: Percutaneous tracheostomy is a safe and viable alternative to surgical tracheostomy in cardiac surgery ICU patients. Patients who undergo PDT have a relatively short duration of tracheostomy and do not have major post-procedural complications.

Background: Pneumonia caused by severe acute respiratory syndrome coronavirus 2 can cause acute respiratory distress syndrome, often requiring prolonged mechanical ventilation and eventually tracheostomy. Both procedures occur in isolation units where personal protective equipment is needed. Additionally, the high bleeding risk in patients with extracorporeal membrane oxygenation (ECMO) places a great strain on surgeons. We investigated the clinical characteristics and outcomes of percutaneous dilatational tracheostomy (PDT) in patients with coronavirus disease 2019 (COVID-19) supported by ECMO, and compared the outcomes of patients with and without ECMO. Methods: This retrospective, single-center, observational study included patients with severe COVID-19 who underwent elective PDT (n=29) from April 1, 2020, to October 31, 2021. The patients were divided into ECMO and non-ECMO groups. Data were collected from electronic medical records at Ajou University Hospital in Suwon, Korea. Results: Twenty-nine COVID-19 patients underwent PDT (24 men [82.8%] and 5 women [17.2%]; median age, 61 years; range, 26-87 years; interquartile range, 54-71 years). The mean procedure time was 17±10.07 minutes. No clinically or statistically significant difference in procedure time was noted between the ECMO and non-ECMO groups (16.35±7.34 vs. 18.25±13.32, p=0.661). Overall, 12 patients (41.4%) had minor complications; 10 had mild subdermal bleeding from the skin incision, which was resolved with local gauze packing, and 2 (6.9%) had dislodgement. No healthcare provider infection was reported. Conclusion: Our PDT approach is safe for patients and healthcare providers. With bronchoscopy assistance, PDT can be performed quickly and easily even in isolation units and with acceptable risk, regardless of the hypo-coagulable condition of patients on ECMO.
