Evaluation of time to intubation and rate of success for different healthcare professionals using a double-lumen left-sided endotracheal video tube: A prospective observational study.

Intubation with a double-lumen left-sided endotracheal video tube has been the standard procedure for nearly five years in the Department of Cardiothoracic Surgery, Copenhagen University Hospital, but no systematic evaluations have been done. For a 12-month period ending November 2017, data were collected from 579 consecutive patients, scheduled for thoracic surgery with a requirement for one-lung ventilation; 35 anaesthetist trainees (nurses or doctors) (287 cases), 27 nurse anaesthetists (239 cases) and 8 anaesthesiologists (53 cases) managed intubation with a double-lumen tube. Time to intubation was relatively equal across healthcare professionals with a mean time of 53 (anaesthetist trainees), 40 (nurse anaesthetists) and 63 (anaesthesiologists) seconds. The shorter time for nurse anaesthetists and prolonged time for anaesthesiologists might be due to the small number of cases and the fact that anaesthesiologists carried out 60% of the cases, where a third attempt was needed, and 25% of cases for the anaesthesiologists were assessed to a Cormack-Lehane grade of 3 or 4 compared to 6% for anaesthetist trainees and 5% for nurse anaesthetists. The rate of successful placement in the first attempt of placing the double-lumen left-sided endotracheal video tube was high, which emphasises that intubation with a double-lumen left-sided endotracheal video tube is suitable for use by different healthcare professionals.

Endotracheal suctioning of the adult intubated patient--what is the evidence?

Intubated patients may be unable to adequately cough up secretions. Endotracheal suctioning is therefore important in order to reduce the risk of consolidation and atelectasis that may lead to inadequate ventilation. The suction procedure is associated with complications and risks including bleeding, infection, atelectasis, hypoxemia, cardiovascular instability, elevated intracranial pressure, and may also cause lesions in the tracheal mucosa. The aim of this article was to review the available literature regarding endotracheal suctioning of adult intubated intensive care patients and to provide evidence-based recommendations The major recommendations are suctioning only when necessary, using a suction catheter occluding less than half the lumen of the endotracheal tube, using the lowest possible suction pressure, inserting the catheter no further than carina, suctioning no longer than 15s, performing continuous rather than intermittent suctioning, avoiding saline lavage, providing hyperoxygenation before and after the suction procedure, providing hyperinflation combined with hyperoxygenation on a non-routine basis, always using aseptic technique, and using either closed or open suction systems.

Listening to music prior to bronchoscopy reduces anxiety - a randomised controlled trial.

Background: Listening to music as a means of relieving anxiety before and during endoscopy has been examined in several studies but results so far are contradictory and inconclusive. Aims: We aimed to determine whether listening to music could reduce anxiety prior to and during bronchoscopy, and whether it is influenced by the patient's preference in music. Methods: 300 patients undergoing bronchoscopy for suspected lung cancer were randomly assigned to: self-selected music, specially-designed music (MusiCureTM), or control (no sound). Spielberger's State-Trait Anxiety Inventory (STAI) was administered three times: at admission, after 20 min with or without music (preceding bronchoscopy), and shortly before discharge. The primary outcome was STAI state score after 20 min, with or without exposure to music prior to bronchoscopy. Results: On average, music reduced the STAI score by 2.5 points (95% CI, 1.1 to 4.0; p < 0.001) compared with the control group. This reduction was largest in the self-selected music group (3.4; 95% CI, 1.5 to 5.3; p < 0.001). In contrast, specially designed music did not significantly reduce STAI score (1.7; 95% CI, -0.3 to 3.6; p = 0.1). Conclusion: Listening to music reduces anxiety in patients undergoing bronchoscopy, provided that the music complies with the patient's preferences.

Music does not alter anxiety in patients with suspected lung cancer undergoing bronchoscopy: a randomised controlled trial.

BACKGROUND: The use of music to relieve anxiety has been examined in various studies, but the results are inconclusive. METHODS: From April to October 2015, 160 patients undergoing examination of pulmonary nodules were randomly assigned to MusiCure or no music. MusiCure was administered through earplugs to ensure blinding of the staff and was played from admission to the operating theatre to the end of the bronchoscopy. Spielberger's State-Trait Anxiety Inventory (STAI) was administered on admission, immediately before bronchoscopy, and on discharge. Secondary outcomes were p-cortisol, physiological variables, dosage of sedatives, movements measured by Actigraph, bronchoscopy duration, number of re-examinations, and overall perception of the sounds in the operating theatre measured by Visual analogue scale. RESULTS: The STAI scores were similar on admission, but after a 10-min wait in the operating theatre, scores varied significantly between patients with and without music, with lower scores in the music group [median (interquartile range, IQR) 35 (18) vs. 43 (25); p=0.03]. Post hoc multiple regression revealed treatment group as insignificant when adjusting for sex and baseline anxiety. However, there was a significantly more positive perception of the sounds in the operating theatre in the music group (median (IQR) 8.2 (1.8) vs. 5.4 (6.8); p<0.0001) and fewer re-examinations in the music group (19.2% vs. 7.7%, p<0.032). CONCLUSIONS: Ten minutes with MusiCure does not alter anxiety when adjusting for baseline anxiety and sex. The current study indicates that this field of research has many confounders.
