Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the change in modified Mallampati grade, after Lumbosacral spine surgery in the prone positionTimepoint: 30 mins, 2 hours, 4 hours, 6 hours & 24 hours after extubation | — |
Secondary
| Measure | Time frame |
|---|---|
| To assess the change in Mentohyoid distance after surgery in prone position. Timepoint: 30 mins, 2 hours, 4 hours, 6 hours & 24 hours after extubation;To assess the change in skin to hyoid bone (SHB) distance measured by ultrasound after surgery.Timepoint: 30 mins, 2 hours, 4 hours, 6 hours & 24 hours after extubation;To assess the change in skin to vocal cord distance measured by ultrasound after surgery.Timepoint: 30 mins, 2 hours, 4 hours, 6 hours & 24 hours after extubation;To assess the change in Thyromental distance after surgery in prone position. Timepoint: 30 mins, 2 hours, 4 hours, 6 hours & 24 hours after extubation;To assess the time required for these changes (clinical and ultrasound parameters) to revert back to preoperative state.Timepoint: 30 mins, 2 hours, 4 hours, 6 hours & 24 hours after extubation;To find correlation between significant airway change defined as increase/change of modified Mallampati class by at least one point with various perioperative parameters like attempts for successful intubation, duration of prone position, duration of surgery, the quantity of intraoperative fluids and blood loss.Timepoint: Postoperative | — |
