Randomized Controlled Trial
Evaluation of the reliability of preoperative descriptive airway assessment tests in prediction of the Cormack-Lehane score: A prospective randomized clinical study.
In this study we investigated and compared the predictive values of different airway assessments tests including thyromental height measurement test, which has been recently suggested, in difficult laryngoscopy (Cormack and Lehane [C-L] scores 3 and 4). In addition, we compared the effectiveness of methods and C-L scores, by IDS, in terms of predicting difficult intubation. ⋯ The present study demonstrates the practicality of TMH as a digitalized test however the clinical benefits of TMH in daily medical practice are drawn into question. The additional variable of race may have had some bearing on this and further studies, larger in patient sample size, may need to use different methodology concerning age-, sex-, and race-dependent variables in evaluating these tests.

Randomized Controlled Trial
The effect of tramadol plus paracetamol on consumption of morphine after coronary artery bypass grafting.
To compare the effects of oral tramadol+paracetamol combination on morphine consumption following coronary artery bypass grafting (CABG) in the patient-controlled analgesia (PCA) protocol. ⋯ Tramadol+paracetamol combination along with PCA morphine improves analgesia and reduces morphine requirement up to 50% after CABG, compared with morphine PCA alone.

Observational Study
Determination of insertion depth of flexible laryngeal mask airway in pediatric population-A prospective observational study.
The purpose of this study was to determine the ideal insertion depth of the flexible laryngeal mask airway (FLMA) by elucidating the relationships between insertion depth and patient's age, body weight, height, and other parameters. We also evaluated an insertion technique that uses the change in intracuff pressure for proper positioning of the FLMA in cases where it is difficult to sense resistance during FLMA insertion. ⋯ The FLMA insertion depth can be calculated using height and weight. Continuous monitoring of intracuff pressure during FLMA insertion is a useful alternative insertion method in cases where resistance is difficult to sense.

Difficult intubation is a significant cause of mortality and morbidity related to anesthesia. We decided to evaluate the value of Modified Mallampati Score, Upper Lip Bite Test and Facial Angle in the prediction of difficult intubation. ⋯ Facial Angle has a high sensitivity, NPV and Youden index for the prediction of difficult intubation, but the best result is achieved when Facial Angle is used in combination with either the Modified Mallampati Score or Upper Lip Bit Test.
