Videolaryngoscopy versus direct laryngoscopy for nasotracheal intubation: A systematic review and meta-analysis of randomised controlled trials
Abstract
Nasotracheal intubation (NTI) is a common practice in the oral and maxillofacial surgeries. A systematic review and meta-analysis was performed to determine whether videolaryngoscopy (VL) compared with direct laryngoscopy (DL) can lead to better outcomes for NTI in adult surgical patients. Only randomised controlled trials comparing VL and DL for NTI were included. The primary outcome was overall success rate and the second outcomes were first-attempt success rate, intubation time, rate of Cormack and Lehane classification 1, rate of Magill Forceps used, rate of postoperative sore throat, and ease of intubation. Fourteen studies with 20 comparisons (n = 1052) were included in quantitative synthesis. The overall success rate was similar between two groups (RR, 1.03; p = 0.14; moderate-quality evidence). VL was associated with a higher first-attempt success rate (RR 1.09; p = 0.04; low-quality evidence), a shorten intubation time (MD-6.72 s; p = 0.0001; low-quality evidence), a higher rate of Cormack and Lehane classification 1 (RR, 2.11; p < 0.01; high-quality evidence), a less use of the Magill forceps (RR, 0.11; p < 0.01; high-quality evidence) and a lower incidence of postoperative sore throat (RR, 0.50; p = 0.03; high-qualit...Continue Reading

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
Allergy and Asthma
Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
