Summary

The investigators assessed upper airway management at the pre-anaesthetic consultation using the usual clinical criteria. On the day before surgery, diabetic patients were assessed for the palm print sign to predict difficult laryngoscopy. After induction of anesthesia, laryngoscopy was performed with a Macintosh metal laryngoscope blade. At this stage of the study, patients were categorized into two groups: difficult and easy laryngoscopy.

Detailed description

During pre-anesthesia consultation, all participants were assessed for airway conditions using usual clinical tests (Mallampati classification, Thyromental distance, mouth-opening test, upper lip biting test (ULBT), Head extension and Prayer sign). Demographic characteristics, diabetes duration, Blood glucose regulation and diabetes-related complications were also recorded. On the day before surgery, patients were assessed for the palm print sign during preoperative evaluation rounds. On the day of surgery, after an intravenous line (IV) and complete monitoring, induction of anesthesia was initiated, and a muscle relaxant was used to facilitate intubation. Laryngoscopy was performed with a Macintosh metal laryngoscope blade by an anesthesiologist who had more than 2 years of intubation experience. McGrath® videolaryngoscope, McCoy laryngoscope, LMA Fastrack®, or i-gel® airway were kept ready for emergency situations. At this stage of the study, patients were categorized into two groups: difficult and easy laryngoscopy.

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	the palm print test	The patient's dominant hand was pressed firmly against a blue ink pad, then onto a white sheet of paper without applying body weight. The palm prints were scored as follows: * Grade 0: All phalangeal areas visible * Grade 1: Deficiency in the interphalangeal areas of the 4th and 5th digits * Grade 2: Deficiency in the interphalangeal areas of the 2nd to 5th digits * Grade 3: Only the tips of the digits visible The palm print test was scored from 0 to 3. Grades 2 and 3 were considered indicators of difficult intubation.
