Lung Ultrasound Score, Obese Patients With Bariatric Surgery
Conditions
Brief summary
this study to compare the ventilation in obese patients either using Driving pressure ventilation technique or conventional protective lung strategy all by using Lung ultrasound score
Interventions
DEVICElung ultrasound
The lung ultrasound score between 0 and 3 (0 = normal A lines, 1 = multiple separated B lines, 2 = coalescing B lines or light beam, 3 = consolidation). The aeration score will be built by the sum of the scores of the 12 segments, with a minimum of 0 and a maximum of 36 according to the aeration loss.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The change in lung ultrasound score | Periprocedural | The primary outcome will be the change in Lung Ultra Sound Score between 0 and 3 (0 = normal A lines, 1 = multiple separated B lines, 2 = coalescing B lines or light beam, 3 = consolidation) from the base line. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hemodynamic parameter as oxygen saturation | Periprocedural | — |
| Hemodynamic parameter as Heart rate | Periprocedural | — |
| Hemodynamic parameter as Mean arterial blood pressure | Periprocedural | — |
| End-tidal carbon dioxide (ETCO2) | Periprocedural | — |
| Lung compliance | Periprocedural | Lung compliance is a measure of the expansion of the lung. |
| Peak airway pressure (Ppeak) | Periprocedural | — |
| Incidence of early postoperative pulmonary complications | At the end of the surgery up to 24 hours after surgery | — |
| Length of post anesthesia care unit PACU stay. | At the end of the surgery up to 2 hours after surgery | — |
| Plateau Pressure (Pplat) | Periprocedural | — |
