The Effects of Lipoabdominoplasty with the Application of Intra-Abdominal Pressure and Respiratory Airway Pressure in Women: A Multicenter Prospective Study.

Background: Abdominoplasty surgery is associated with intra-abdominal pressure (IAP) and respiratory airway pressure (RAP) changes. We aimed to assess the impact of the lipoabdominoplasty on the simultaneous changes in the IAP and RAP and their predictive factors for the first time.

Methods: This prospective study was conducted on 30 women who underwent lipoabdominoplasty between November 2021 and November 2022 in Modares and 15- Khordad hospitals affiliated with Shahid Beheshti University of Medical Sciences, Tehran, Iran. Patients underwent lipoabdominoplasty by a surgeon with more than ten years of experience. RAP was measured based on P platue and P Peak three times (after anesthesia, after plication, and after surgery).

Results: The mean changes of IAP and RAP were significantly different based on the p peak and p plateau after anesthesia, plication, and surgery (P<0.001). Changes in IAP with BMI, degree of laxity, degree of plication, number of pregnancies, xiphoid to pubis distance, and 12th vertebra to ASIS distance were related. RAP (p peak and P platue) with a degree of laxity, degree of plication, number of pregnancies, IAP, xiphoid to pubis distance, and 12th vertebra to ASIS distance were related (P<0.05).

Conclusion: lipoabdominoplasty significantly affects changes in IAP and RAP after anesthesia, plication, and surgery. During lipoabdominoplasty, surgeons should simultaneously pay attention to the changes in both IAP and RAP from the beginning to the end of the surgery, especially in obese women with a history of multiple pregnancies and patients with severe laxity.
