erector spinae block, diaphragmatic dysfunction, morbidly obese
Brief summary
postoperative diaphragmatic dysfunction is critical especially in morbidly obese patients
Detailed description
Investigators aimed to evaluate the impact of erector spinae plane block on the incidence of postoperative diaphragmatic dysfunction in morbidly obese patients (Body mass index more than or equal 40)
Interventions
DEVICEDiaphragmatic ultrasound
diaphragmatic excursion will be conducted at baseline and at 2 and 24 hours postoperatively

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of diaphragmatic dysfunction in both groups | baseline and 2 hours after surgery | postoperative diaphragmatic excursion 10 mm at 2 hours after surgery |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Forced expiratory volume at one second | at baseline, 2 and 24 hours postoperatively | FEV1 (in liter) |
| numeric rating scale | at 24 hours after surgery | score from zero to 10 |
| Forced vital capacity (in Liter) | at baseline, 2 hours, and 24 hours after surgery | FVC (in liter) |
| Peak expiratory flow rate (Liter/sec) | baseline, 2 hours, and 24 hours | PEFR (Liter/sec) |
