Design outcomes
Primary
| Measure | Time frame |
|---|---|
| verify if the measurements of the seroma differ according to the presence of scarpa fascia in 46 patients submitted to an abdominoplasty. All patients had the measurement of the drained liquid (seroma) in ml daily (volume of the drainage in 24 hours) by means of a closed suction drain. A 20 ml syringe was used to measure the drained volume. The first 16 cases in each group were used as a pilot for the calculation of the sample. Fascia maintenance is expected to result in a 40% reduction in the amount of seroma and reduce at least 2 days in the use of the drain. With 80% power and 95% confidence, the required sample of women for the study should be 18 in each group, considering that the largest sample obtained was aimed at the difference in the amount of seroma.;It was observed that the mean volume in the group with preservation of the fascia was 249.1 ml, while the group without preservation presented a mean of 428.9, a statistically higher volume (p = 0.003) as evidenced by t-student test and Mann-whitney test. | — |
Secondary
| Measure | Time frame |
|---|---|
| Permanence on days with the drainage of the abdomen until the volume was less than 30 ml in 24 hours and volume of extracellular fluid in the subcutaneous (seroma) of abdominal wall measured by ultrasonography on the 20th postoperative day;It was observed that the drainage time in patients with fascia preservation was on average 4.2 days, compared with 5.4 days in the fascia group, a significantly lower finding (p = 0.003). On the 20th postoperative day, the ultrasound volume was 16.8 ml in the preservation group and 21.6 ml without the fascia, statistically the same in the two groups of patients (p = 0.809), as evidenced by t-student test and mann-whitney test. | — |
