Bleed or not to bleed in Bariatric surgery- Intraoperative measures can prevent post op bleeding

The key findings of this study were:

1. 200 patients were included in the study, split into the two categories above. Group A's average ages are 44.49 +/- 8.49 and 43.73 +/- 9.28.

2. For Group A, the mean preoperative BMI is 45.6 kg/m2 6.71 and for Group B, it is 48.9 7.15 kg/m2.

3. Group A measured a mean MAP of 83.06 18.58 mmHg, while group B measured 111.88 12.46 mmHg (p 0.05, z-score: 4.15226, and U: 13,900).

4. In group A, there were 9 cases of bleeding that were noted; the majority of them received medical care and blood transfusions; only one hemodynamically unstable patient underwent a second laparoscopy.

5. Only two incidences of bleeding in group B were documented by the researchers, one of which necessitated blood transfusions.

In conclusion, researchers were able to lessen postoperative hemorrhage thanks to these efforts. This approach can be a fantastic place to start, but additional prospective trials will be needed to determine whether lowering pneumoperitoneum pressure of CO2 and normalizing intraoperative blood pressures are safe and whether they can reduce the risk of postoperative hemorrhage.
