AIMS: To evaluate the ink impression made by the palm of the dominant hand as a screening tool for difficult laryngoscopy in diabetic patients. SUBJECTS AND METHODS: In this prospective study, airway of 50 adult diabetic patients, undergoing elective surgery under general anaesthesia, was assessed preoperatively using the common clinical indices such as Modified Mallampati test, thyromental distance, degree of head extension and a specific index- the palm print test. Following induction of anaesthesia and neuromuscular relaxation, laryngoscopy was performed and the laryngoscopic view scored. The sensitivity, specificity and positive predictive value of each airway evaluation index were calculated. RESULTS: The incidence of difficult laryngoscopy was 16%. The palm print test had the highest sensitivity (75%) of all the indices. The thyromental distance less than six cm had the highest specificity (95.2%) but was least sensitive (25%). 87% of patients with difficult laryngoscopy had two or more indices abnormal. CONCLUSION: Though the palm print test was the most sensitive index of the four indices studied, a better prediction of difficult laryngoscopy can be achieved by evaluating all the four airway indices preoperatively.
