Impact of Universal Use of the McGrath Videolaryngoscope as a Device for All Intubations in the Cardiac Operating Room. A Prospective Before-After VIDEOLAR-CAR Study.

Objective: Tracheal intubation in cardiac surgery patients has a higher incidence of difficult laryngoscopic views compared with patients undergoing other types of surgery. The authors hypothesized that using the McGrath Mac videolaryngoscope as the first intubation option for cardiac surgery patients improves the percentage of patients with "easy intubation" compared with using a direct Macintosh laryngoscope.

Design: A prospective, observational, before-after study.

Routine laboratory screening for acute and recent HIV infection in Lima, Peru.

Background: Before implementing screening programmes for acute HIV infection in developing countries, key issues, including cost, feasibility and public health impact, must be determined.

Objective: Fourth-generation enzyme immunoassay (EIA) was compared with HIV-1 RNA PCR for the detection of acute and early HIV infection in counselling and testing populations in Lima, Peru.

Methods: Adults presenting for HIV testing at designated clinics in Lima-Callao, Peru were offered additional screening for acute HIV infection.
