About

The respiratory system receives mechanical power (MP) throughout time during mechanical ventilation. Despite its life-saving benefits, mechanical ventilation can cause ventilator-induced lung injury (VILI). Recently, VILI has been linked to mechanical power, or the amount of energy the mechanical ventilator sends to the respiratory system in a given time. The hunt for lung damage-reducing characteristics, notably after VILI and ARDS (Acute respiratory distress syndrome), has increased after Covid-19. Mechanical power must be used more to promote lung protection. We examined the effects of bilateral rectus sheath and OSTAP (Oblique Subcostal Transversus Abdominis Plane ) block on mechanically powered patients.

Full description

MP is the energy transmitted over time to the respiratory system during mechanical ventilation. Although mechanical ventilation is a life-supporting treatment, it has the potential to cause damage to the lung structure in a process referred to as VILI. Recently, the degree of VILI has been associated with the amount of energy transmitted to the respiratory system by the mechanical ventilator within a specific time frame, which is referred to as mechanical power. After the occurrence of Covid-19, the search for parameters to reduce lung damage, especially following VILI and ARDS, has become more prominent. In this regard, promoting lung protection requires the more widespread use of mechanical power. We aimed to investigate the effect of bilateral rectus sheath and OSTAP block applied to patients on mechanical power.

---

66 participants in 2 patient groups

Group 1:OSTAPand RSB

Active Comparator group

Description:

Group 1 will consist of patients who received general anesthesia, and just before the surgery started, bilateral OSTAP and RSB will be performed.

Treatment:

Procedure: Bilateral Rectus Sheath Block (RSB) will be performed.

Procedure: Bilateral Oblique Subcostal Transversus Abdominis Plane Block (OSTAP) will be performed.

Group 2: Intravenous analgesia

No Intervention group

Description:

Group 2 will include patients who received general anesthesia and were administered intravenous analgesia approximately 30 minutes before the end of the operation.
