Impact of universal use of a hyperangulated videolaryngoscope as the first option for all intubations in the ICU: A prospective before-after study.

BACKGROUND: Tracheal intubation in ICU is associated with high incidence of difficult intubations. The study aimed to investigate whether the "universal" use of a hyperangulated videolaryngoscope would increase the frequency of "easy intubation" in ICU patients compared to direct laryngoscopy. METHODS: A prospective before-after study was conducted. The pre-interventional period (36 months) involved tracheal intubations using direct laryngoscopy as the first intubation option. In the interventional period (18 months) a hyperangulated videolaryngoscope was the first intubation option. The primary outcome was the percentage of patients with "easy intubation" defined as intubation on the first attempt and easy laryngoscopy (modified Cormack-Lehane glottic view of I-IIa). Secondary outcomes included difficult laryngoscopy, operator technical difficulty, and complications. RESULTS: We enrolled 407 patients, 273 in non-interventional period, and 134 in interventional period. Tracheal intubation in the interventional period was associated with higher incidence of "easy intubation" (92.5%) compared with the non-interventional period (75.8%); P < 0.001)). Glottic visualization improved in the interventional period, with a reduced incidence of difficult laryngoscopy (1.5% vs. 22.5%; P < 0.001). The proportion of first-success rate intubation was 92.5% in the interventional period, and 87.8% in the non-interventional period (P = 0.147). Moderate and severe technical difficulty of intubation reported decreased in the interventional period (6% vs. 17.6%; P < 0.001). There was no significant difference between both periods in the incidence of complications. CONCLUSION: "Universal" use of hyperangulated videolaryngoscopy for tracheal intubation in patients admitted in ICU improves the percentage of easy intubation compared to direct laryngoscopy.

Videolaryngoscope versus conventional technique for insertion of a transesophageal echocardiography probe in intubated ICU patients (VIDLARECO trial): A randomized clinical trial.

BACKGROUND: Transesophageal echocardiogram probe insertion in intubated critically ill patients can be difficult, leading to complications, such as gastric bleeding or lesions in the oropharyngeal mucosa. We hypothesised that the use of a videolaryngoscope would facilitate the first attempt at insertion of the transesophageal echocardiogram probe and would decrease the incidence of complications compared to the conventional insertion technique. METHODS: In this clinical trial, patients were randomly assigned the insertion of a transesophageal echocardiogram probe using a videolaryngoscope or conventional technique. The primary outcome was the successful transesophageal echocardiogram probe insertion on the first attempt. The secondary outcomes included total success rate, number of insertion attempts, and incidence of pharyngeal complications. RESULTS: A total of 100 intubated critically ill patients were enrolled. The success rate of transesophageal echocardiogram probe insertion on the first attempt was higher in the videolaryngoscope group than in the conventional group (90% vs. 58%; absolute difference, 32%; 95% CI 16%-48%; p < 0.001). The overall success rate was higher in the videolaryngoscope group than in the conventional group (100% vs. 72%; absolute difference, 28%; 95% CI 16%-40%; p < 0.001). The incidence of pharyngeal mucosal injury was smaller in the videolaryngoscope group than in the conventional group (14% vs. 52%; absolute difference, 38%; 95% CI 21%-55%; p < 0.001). CONCLUSIONS: Our study showed that in intubated critically ill patients required transesophageal echocardiogram, the use of videolaryngoscope resulted in higher successful insertion on the first attempt with lower rate of complications when compared with the conventional insertion technique.
