The mean experience of the anaesthesiologists was 5.3 years, post-anaesthesia training. Immediately after each intubation, the concerned anaesthesiologists were asked to fill an electronic feedback form. It was part of an audit on compliance to institute protocol. In the 9 patients where no intubation box was used, all the intubations were successful in the first attempt. In the other 21 patients, successful intubation in the first attempt was possible in 8 patients (38.1%). Second attempt was required in 6 (28.6%) patients, removal of the intubation box was needed in 6 (28.6%) patients, and 1 patient had change of operator. Thus, the cumulative success rate (first and second attempt) of endotracheal intubation using the box was 66.6% (figure 1). The reasons for removal of the intubation box were poor vision and inadequate space for certain manoeuvres such as tilting the patient's head. For the question whether the intubation box restricted the movements and hindered the process of intubation -76.6% responded by saying, "yes", and when asked to rate the ease of intubation on a scale of 1 to 10 through the intubation box, the median score given was 4.
