https://www.selleckchem.com/HSP-90.html tracheostomy tubes of 7 to 9.5 mm internal diameter can be passed over the introducer and placed inside the airway. Even though the percutaneous tracheostomy procedure described in this study

incorporates technical principles of at least two different methods the mean procedure time (5.1 minutes) was consistent with single dilator techniques reported by others [10, 13, 21, 27]. Acute complications with the percutaneous tracheostomy method described by us were restricted to hemorrhage. The post-procedure bleeding rate of 2% in our study is comparable to other reports (1.6 – 4%) [3–5, 10, 11, 15, 18, 19, 23, 24]. Even though comparison of the method described herein was not the purpose of this study, a contemporary analysis of 30 open surgical tracheostomies performed in our institution showed a 4% incidence of post-procedure bleeding, selleckchem BKM120 in vivo 50% of those cases required a surgical intervention to control the hemorrhage (unpublished data- Joao B. Rezende-Neto). On the contrary, none of the percutaneous tracheostomy patients who

had a bleeding complication required a surgical intervention in the present study. Interestingly, prothrombin (Quick Value) time and INR were equivalent among the patients, respectively; 80.9 ± 5.5% in percutaneous tracheostomy vs. 87.2 ± 3.1% in open surgical tracheostomy patients (p = 0.27, Student’s t-Test), and 1.2 ± 0.1 in percutaneous tracheostomy vs. 1.3 ± 0.15 in open surgical tracheostomy

patients (p = 0.64, Student’s t-Test). Furthermore, time to perform time to perform percutaneous tracheostomy was significantly shorter than that of open surgical www.selleck.co.jp/products/E7080.html tracheostomy (5.1 ± 0.3 minutes vs. 12.2 ± 1.4 minutes; p < 0.001, Student’s t-Test) Several studies highlight the importance of bronchoscopy to reduce complications during percutaneous tracheostomies, and most institutions routinely perform the procedure under bronchoscopic guidance [4, 11, 18, 19, 24, 28–32]. Unfortunately, our institution did not have bronchoscopy routinely available during the study period. Even though bronchoscopy is considered an important adjunct to percutaneous tracheostomy, that enables confirmation of midline puncture of the trachea, correct position of the guidewire and the tracheostomy tube, as well as, visualization of posterior tracheal wall injury, it is not without complications [4, 31, 33, 34]. Studies have shown that bronchoscopy can cause hypoventilation that leads hypercarbia and respiratory acidosis during percutaneous tracheostomy [12, 35, 36]. Nonetheless, percutaneous tracheostomy without bronchoscopic guidance remains a controversial issue [4, 12, 19, 29, 31, 34, 37–40].
