Percutaneous dilatational tracheostomy

Cricothyrotomy - In Unanticipated Difficult Intubation Cases with Respiratory Compromise

Introduction  Cricothyrotomy, percutaneous dilation tracheostomy, and tracheostomy are all cost-effective and safe techniques used in the management of critically ill patients who need an artificial airway other than endotracheal tube ventilation. The present study focused on enlightening on elective and emergency procedures performed on conditions present with difficult airways and also attempts to shed light on the aspects of securing an airway in anticipated and unanticipated difficult intubation. Objective  The objective of the study was to compare the three procedures conducted during difficult airway/failed intubation situations. Methods  The present retrospective observational study was conducted collecting data from patient files obtained at a tertiary healthcare center from 2013 to 2018. The difficult intubation cases were managed by ear, nose, and throat (ENT) surgeons. The study compared three methods: Cricothyrotomy, percutaneous dilation tracheostomy, and tracheostomy based on factors such as procedure duration, complications, and the instruments required for each procedure. Results  The study enrolled 85 patients, 61 males and 24 females, aged between 30 and 70 years old. To perform cricothyrotomy, only a simple blade was required. Cricothyrotomy had the shortest operating time (4.1±3.1 minutes) and the shortest time of full oxygen saturation (3 min). Percutaneous tracheostomy had the least amount of bleeding (1%). Cricothyrotomy significantly showed the least intraoperative bleeding than percutaneous dilation, tracheostomy, and tracheostomy ( p  = 0.001). Conclusion  Cricothyrotomy is preferable as it takes less time to perform, causes less bleeding, and takes the least time for full oxygen saturation than tracheostomy and percutaneous dilatational tracheostomy in "can't intubate, can't oxygenate" patients.

Comparison between Real-Time Ultrasound-guided Percutaneous Dilatational Tracheostomy and Surgical Tracheostomy in critically ill Patients: A Randomized Controlled Trial

OBJECTIVES

Tracheostomy is an important procedure for critically ill patients in the intensive care unit (ICU), and percutaneous dilatational tracheostomy (PDT) has gained popularity due to its safety and effectiveness. However, there are limited data comparing ultrasound-guided PDT (US-PDT) with surgical tracheostomy (ST). In our previous study, we reported that US-PDT had similar safety and effectiveness to ST, with a shorter procedure time. However, the study design was retrospective, and the sample size was small. Therefore, we conducted a randomized controlled trial to demonstrate the safety and efficacy of US-PDT compared to ST.

METHODS

A total of 70 patients who underwent either US-PDT (n=35) or ST (n=35) were enrolled in the study between October 20, 2020 and July 26, 2022. The patients were randomly assigned to their respective procedures. The data collected included patient clinical characteristics, procedure time and details, complications, duration of ICU stay, time taken for weaning from mechanical ventilation, and hospital mortality.

RESULTS

The procedure time of US-PDT was shorter than that of ST (4.0±2.2 minutes vs. 10.1±4.6 minutes). The incision length of US-PDT was also shorter than that of ST (1.5±0.5 cm vs. 1.8±0.4 cm). There were no statistically significant differences in demographics, procedure details, complications, length of ICU stay, ventilator weaning time, and hospital mortality.

CONCLUSION

US-PDT has a similar complication rate and shorter procedure time compared with ST. It can be safely and effectively performed in critically ill patients and can serve as a potential alternative to ST.

Unusual bronchoscopic value in percutaneous dilatational tracheostomy: A case report

BACKGROUND

The usage of bronchoscopy during percutaneous dilatational tracheostomy remains under debate. The proponents of bronchoscopy advocating safety of the procedure, whereas the critics raising the concerns about the cost, possible delay in the procedure, and waiting for the device.

CASE SUMMARY

We are highlighting a case of percutaneous dilatational tracheostomy where bronchoscopy aided in diagnosing a rare situation of wire entrapment within the endotracheal tube, treated by withdrawing the wire from the endotracheal tube with good outcome.

CONCLUSION

The bronchoscopy guided approach permitted early diagnosis and helped to end the procedure without complication or possible major surgery in a case of accidental wire puncture of the endotracheal tube.

Comparison of outcomes between vertical and transverse skin incisions in percutaneous tracheostomy for critically ill patients: a retrospective cohort study

Background

Percutaneous tracheostomy (PT) is a common procedure in critical care medicine. No definite clinical practice guidelines recommended on the choice of the direction of skin incision, vertical or transverse for tracheostomy in critically ill patients. The objective of this retrospective study was to compare the outcomes associated with vertical and transverse skin incisions in patients undergoing PT.

Methods

Patients who underwent PT between March 2011 and December 2015 in the intensive care unit (ICU) of a tertiary hospital were retrospectively included. PTs were performed by pulmonary intensivists at the ICU bedside using the single tapered dilator technique assisted by flexible bronchoscopy. The primary outcome was the incidence of tracheostomy site ulcers at 7 days after PT.

Results

Of the 458 patients who underwent PT, a vertical incision was made in 27.1% and a transverse incision was made in 72.9%. There were no tracheostomy-related mortalities, and no significant difference in the incidence of immediate postoperative complications, including bleeding, tracheal ring fracture, and subcutaneous emphysema. Thirty-five patients (7.6%) developed complications within 7 days after PT, in which tracheostomy-related pressure ulcers were the most frequent. Compared with vertical incisions, transverse incisions were associated with significantly lower incidence of complications (14.1% vs. 5.4%, P = 0.001).

Conclusions

This retrospective study showed that transverse skin incisions in PTs for critically ill patients, resulted in a significant decrease in overall complications, particularly ulcers in the tracheostomy site.
