Alteration of Modified Mallampati Score
Conditions
Keywords
Modified Mallampati score, Cesarean delivery
Brief summary
Mallampati class change has not been well evaluated during the cesarean delivery. Various factors regarding to cesarean delivery might influence this changes. The aim of this study was to evaluate the Mallampati class before and after cesarean delivery and to identify predictive factors of the changes.. Study Type: Observational Cross-sectional study
Detailed description
Mallampati class, thyromental distance, neck circumference, and upper lip bite test were evaluated at four time intervals : during pre-anesthetic visit (T0), 1-hour (T1), 6-hour (T2), and 24-hour after delivery (T3).
Interventions
OTHEREvaluate upper airway changes
Evaluate upper airway changes at several point of time before and after cesarean delivery

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate Modified Mallampati score changes before and after cesarean delivery | up tp 2 days | Modified Mallampati score (score 1-4;1= easy airway and 4 = difficult airway) before delivery, 2 and 6 hours after delivery, and post-operative day1 (the day of surgery and post-operative day 1) |
| Evaluate thyromental distance changes before and after cesarean delivery | up tp 2 days | thyromental distance (centimeter) before delivery, 2 and 6 hours after delivery, and post-operative day1 (the day of surgery and post-operative day 1) |
| Evaluate upper lip bite score changes before and after cesarean delivery | up to 2 days | Upper lip bite score (score 1-4; 1 = easy airway and 4 = difficult airway) before delivery, 2 and 6 hours after delivery, and post-operative day1 (the day of surgery and post-operative day 1) |
| Evaluate neck circumference changes before and after cesarean delivery | up to 2 days | Neck circumference (centimeter) before delivery, 2 and 6 hours after delivery, and post-operative day1 (the day of surgery and post-operative day 1) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Intraoperative intravenous fluid and Alteration of Modified mallampati score | up tp 2 days | Evaluate the percentage of patients whose mallampati score increase from baseline between patient who recieved intravenous fluid ≥ 2000 ml and \< 2000 ml |
| Estimate blood loss and Alteration of Modified mallampati score | up tp 2 days | Evaluate the percentage of patients whose mallampati score increase from baseline between patient whose estimate blood loss≥ 1000 ml and \< 1000 ml |
| Oxytocin dosage and Alteration of Modified mallampati score | up tp 2 days | Evaluate the percentage of patients whose mallampati score increase from baseline between patient who recieved high dose oxytocin (≥ 0.6 U/minl) and low dose oxytocin ( \<0.6 U/min ) |
