To assess practicability and safety of the Ciaglia Blue Rhino (Cook Critical Care, Bloomington, IL)-an extensively modified technique of percutaneous dilatational tracheostomy-50 critically ill adults on long-term ventilation underwent either new Ciaglia Blue Rhino or percutaneous dilatational tracheostomy in a prospective, randomized clinical trial.
The present data show the feasibility of closed chest single- and double-vessel revascularization, with good clinical results. However, procedural time is prolonged and the complex endoscopic and endoaortic occlusion techniques, as well as the extensive anesthesiologic monitoring, are demanding. The need for conversion to an open procedure diminished after a relatively short learning curve. All postulated benefits of totally endoscopic surgery other than excellent cosmesis must be evaluated in larger cohorts.
Background:The Bonfils intubation fibrescope (BIF), a rigid, straight and reusable fibreoptic device, is being used increasingly to facilitate endotracheal intubation after direct laryngoscopy has failed. We tested the hypothesis that, with the BIF compared to direct laryngoscopy, the rate of failed endotracheal intubation could be reduced in patients with a difficult airway, simulated by means of a rigid cervical immobilization collar.Methods: Seventy-six adults undergoing elective gynecological surgery under general anesthesia were randomly assigned to have endotracheal intubation, facilitated with either a standard size 3 Macintosh laryngoscope blade, or the BIF. A rigid cervical immobilization collar was used to simulate a difficult airway, by reducing mouth opening and limiting neck extension. If endotracheal intubation could not be achieved within two attempts, the cervical collar was removed, and direct laryngoscopy was performed thereafter, using a Macintosh blade in all subjects. The success rate of endotracheal tube placement was the primary outcome variable. Results: Patient characteristics were similar in the two groups. After neck immobilization, the inter-incisor distance was reduced to 2.6 ± 0.7 cm (Macintosh) and 2.6 ± 0.8 cm (BIF). Tube placement was successful in 15/38 (39.5%) patients with a Macintosh blade, and in 31/38 patients with the BIF (81.6%; P = 0.0003). Time required for tube placement was 53 ± 22 sec (Macintosh) and 64 ± 24 sec (BIF; P = 0.15).
Conclusion:The Bonfils intubation fibrescope is a more effective intubating device for patients with immobilized cervical spine and significantly limited inter-incisor distance, when compared to direct laryngoscopy.
SummaryThe safety of percutaneous tracheostomy in 73 obese patients (body mass index ‡ 27.5 kg.m )2 ) in a cohort of 474 adults was studied. Four percutaneous techniques were employed (percutaneous dilational tracheostomy, n = 48; Ciaglia Blue Rhino, n = 157; guide wire dilating forceps, n = 62, translaryngeal tracheostomy, n = 207). The overall complication rate was 43.8% (n = 32) in the obese group compared to 18.2% (n = 73) in the control group (p < 0.001). Seven (9.6%) obese patients suffered life-threatening complications compared to three non-obese patients (0.7%, p < 0.001). Obese patients had a 2.7-fold increased risk for peri-operative complications, and a 4.9-fold increased risk for serious complications. The data suggest that percutaneous tracheostomy in obese patients is associated with a considerably increased risk for peri-operative complications, especially for serious adverse events.
Since the publication of the first german guidelines on airway management in 2014, new techniques have been established in the clinical routine and new insights into existing strategies have been published. As a consequence the new guidelines on airway management of the German Society of Anesthesiology and Intensive Care Medicine represent the current state of scientific knowledge and integrate the currently recommended techniques and strategies. The aim of these guidelines is to guarantee an optimal care of patients undergoing anesthesiological procedures and serve as an orientation and decision aid for users.
