However, the contribution of each of these in improving ease of intubation is quite different. We evaluated the role of video camera in the performance of laryngoscopy by using the universal serial bus (USB) videolaryngoscope in patients with predicted difficult airway.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Sixty patients in the age group of 25 to 65 years having Mallampati grade III or IV were randomly allocated to two groups. All patients were American Society of Anesthesiologists physical status grade I or II and planned for elective surgical procedure under general anesthesia. USB videolaryngoscope or Macintosh laryngoscope was used for intubation as per group allotted. Comparison of time of endotracheal intubation was our primary outcome measure and it was calculated from the time the laryngoscope tip passes the incisors to the initial appearance of capnography wave. Rate of successful intubation, number of attempts needed for successful tube placement, optimisation manoeuvres used, changes in haemodynamic parameters and airway injuries were evaluated as secondary outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Time for intubation was shorter in the Macintosh group than the USB group (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.024).
