Compression between palm print test and mallampatie test in recognition of difficult airway in diabetic patients in Imam Khomeini and Golestan hospitals

Respiratory events are the most common anesthetic related injuries following dental damage. Most physical examination indices developed to aid in preoperative evaluation of all patients presenting for layngoscopy and tracheal intubation fail to identify many difficult to intubate patients. 1/3 of diabetic patients are difficult for laryngoscopy. This study about was designed to compare palm print test with mallampatie in 103 diabetic patients in Imam Khomeini & Golestan hospitals. In this study 103 diabetic patients either type I or type II was randomly selected. Mallampatie, Palm print and thyromental distance test in recognition of difficult intubation patients was compared. Our study revealed that about 1/10 of diabetic patients are difficult to intubate. Sensitivity and specificity of palm print test in recognition of difficult intubation diabetics was 100% and 97% and sensitivity and specificity of mallampatie 30% and 91/4%. This study suggests that all the tests have their place in armamentarium of anesthesiologist, in diabetics palm print is the best single predictor of difficult intubation. We also feel that diabetic patients in our population are generally not difficult to intubate.
