When and how should we do a tracheostomy?

Effect of technique and timing of tracheostomy in patients with acute traumatic spinal cord injury undergoing mechanical ventilation

OBJECTIVE

To assess the effect of timing and techniques of tracheostomy on morbidity, mortality, and the burden of resources in patients with acute traumatic spinal cord injuries (SCls) undergoing mechanical ventilation.

DESIGN

Review of a prospectively collected database.

SETTING

Intensive and intermediate care units of a monographic hospital for the treatment of SCI.

PARTICIPANTS

Consecutive patients admitted to the intensive care unit (ICU) during their first inpatient rehabilitation for cervical and thoracic traumatic SCI. A total of 323 patients were included: 297 required mechanical ventilation and 215 underwent tracheostomy.

OUTCOME MEASURES

Demographic data, data relevant to the patients' neurological injuries (level and grade of spinal cord damage), tracheostomy technique and timing, duration of mechanical ventilation, length of stay at ICU, incidence of pneumonia, incidence of perioperative and early postoperative complications, and mortality.

RESULTS

Early tracheostomy (<7 days after orotracheal intubation) tracheostomy was performed in 101 patients (47%) and late (> or = 7 days) in 114 (53%). Surgical tracheostomy was employed in 119 cases (55%) and percutaneous tracheostomy in 96 (45%). There were 61 complications in 53 patients related to all tracheostomy procedures. Two were qualified as serious (tracheoesophageal fistula and mediastinal abscess). Other complications were mild. Bleeding was moderate in one case (late, percutaneous tracheostomy). Postoperative infection rate was low. Mortality of all causes was also low.

CONCLUSION

Early tracheostomy may have favorable effects in patients with acute traumatic SC. Both techniques, percutaneous and surgical tracheostomy, can be performed safely in the ICU.

Tracheostomy: how and when should it be done in cardiovascular surgery ICU?

BACKGROUND

The aim of this study was to assess the effect of timing and techniques of tracheostomy on mortality and morbidity in cardiovascular surgery patients.

METHODS

Between January 2000 and October 2007, a total of 19,559 cardiac and vascular operations were performed in our hospital, and 205 of these patients (1.04%) who underwent a tracheostomy procedure were included in this retrospective study.

RESULTS

Surgical tracheostomy (ST) was employed in 134 (65.4%) and percutaneous tracheostomy (PT) in 71 (34.6%) of the cases. There were 17 complications related to all tracheostomy procedures in 15 (7.3%) patients. Bleeding, requiring surgical intervention, occurred in five (3.7%) ST patients and in one (1.4%) PT patient. Cardiac arrest related to the procedure occurred in two (1.5%) ST patients. Pneumothorax occurred in three (2.2%) ST patients and in one (1.4%) PT patient, subcutaneous emphysema in three (2.2%) ST patients and in one (1.4%) PT patient, and tracheoesophageal fistula in one (0.7%) ST patient (p>0.05). The postoperative infection rate was significantly lower, and cooperation of the patients, postoperative patient mobilization, and oral feeding rates were higher in the early tracheostomy group. The multifactorial mortality rates of early (<seven days) and late tracheostomies were 71.4% and 88.1%, respectively (p=0.037).

CONCLUSIONS

We believe that both techniques can be performed safely in the ICUs. Although the need of tracheostomy is one of the foremost causes of mortality and morbidity in cardiovascular surgery patients, an early application of the procedure may have favorable effects on the expected mortality and overall infection rates of the critically ill patients.

Mechanical Ventilation

Mechanical ventilation is the second most frequently performed therapeutic intervention after treatment for cardiac arrhythmias in intensive care units today. Countless lives have been saved with its use despite being associated with a greater than 30% in-hospital mortality rate. As life expectancies increase and people with chronic illnesses survive longer, artificial support with mechanical ventilation is also expected to rise. In one survey, over half of senior internal medicine residents reported their training on mechanical ventilation as inadequate, whereas the majority of critical care nurses reported having received no formal education on its use. Technological advances resulting in the availability of sleeker ventilators with graphic waveform displays and new modes of ventilation have challenged the bedside clinicians to incorporate this new data along with evidenced-based research into their daily practice. A review of current thoughts on mechanical ventilation and weaning is presented.

Percutaneous tracheostomy with the guide wire dilating forceps technique: presentation of 171 consecutive patients

BACKGROUND

Evaluation of percutaneous tracheostomy (PT) with the guide wire dilating forceps (GWDF) technique.

METHODS

Prospective study of perioperative complications, retrospective analysis of early and late complications in an ICU in a teaching university hospital.

RESULTS

The success rate of the procedure was 96.5%. The average procedure time in 171 consecutive patients was 5.0 min. Perioperative complications requiring surgical or medical intervention occurred in 6.4% of 171 patients. This included conversion to surgical tracheostomy, which was necessary in six patients (3.5%). Major complications while being cannulated occurred in 2.4% of 164 patients but seemed mostly unrelated with the GWDF technique itself. Late complications (after decannulation) were mostly minor and occurred in 22.6% of 106 patients. Only one patient (0.9%) had a symptomatic tracheal stenosis developed.

CONCLUSION

Percutaneous tracheostomy with the guide wire dilating forceps technique is easy to perform at the bedside with few late complications. However, in our study, perioperative and immediate postoperative bleeding complications (minor and major) occur quite often.
