Brief Summary

In laparoscopic surgeries; a trocar is inserted through a small incision and an intervention is made into the peritoneal cavity. Approximately 3-4 liters of carbon dioxide (CO2) insufflation (inflating the abdominal cavity with carbon dioxide gas) is applied and the intra-abdominal pressure is adjusted to 10-20 mmHg. Laparoscopic cholecystectomy operation is routinely performed with 12 mmHg and 14 mmHg pressures in our operating room, and the preferred pressure value is; It is determined by the surgical team to be the most appropriate value for the patient and the operation. Both pressure values applied to the patients intraoperatively are within safe ranges. The mechanical power of ventilation (MP) is the amount of energy transferred per unit time from the mechanical ventilator to the respiratory system. Although this energy is mainly used to overcome airway resistance, some of it directly affects the lung tissue, potentially causing ventilator induced lung injury (VILI). To prevent ventilator-associated lung injury, it requires the mechanical ventilator to be adjusted so that the least amount of energy is transferred to the respiratory system per unit time for each patient. In the results obtained in the published studies; increased mechanical strength has been associated with increased in-hospital mortality, higher hospital stay and higher ICU follow-up requirement. The aim of this study is to investigate the effect of two different intra-operative intra-abdominal pressure levels applied to patients who underwent laparoscopic cholecystectomy under general anesthesia on 'Mechanical Power (MP)'.

Outcome Measures

Primary Outcomes (1)

  • ventilator-induced lung injury (barotrauma)

    mechanical power values measured during operation will be recorded

    during the operation

Study Arms (2)

Group 12 mmHg

All patients in this group will be operated with an insufflation pressure of 12 mmHg during laparoscopic cholecystectomy surgery.

Other: mechanical power measurement

Group 14 mmHg

All patients in this group will be operated with an insufflation pressure of 14 mmHg during laparoscopic cholecystectomy surgery.

Other: mechanical power measurement

Interventions

Mechanical power values of the patients; * Before insufflation (baseline value), * 0 min after insufflation, * 15th min after insufflation, * 30 minutes after insufflation, * 45th minute after insufflation (if insufflation continues), * 60th minute after insufflation (if insufflation continues), * Intraoperative after insufflation It will be measured with the following formula in the specified periods. MP = 0.098 x minute ventilation x \[Peak inspiratory pressure - 0.5 x (Plateau pressure - Positive end-expiratory pressure)\]

Sampling MethodProbability Sample
Study Population

200 patients who will be operated for laparoscopic cholecystectomy at Erciyes University between May 2023 and Oct 2023 will be included in our study.

You may qualify if:

  • Patients with ASA 1-2
  • The patient's willingness to participate in the study voluntarily

You may not qualify if:

  • Patients with ASA 3-4
  • Patients with lung disease such as pneumonia, COPD attack before the operation
  • Patients undergoing other surgical procedures or anesthesia technique
  • Pregnant patients
  • Patients with morbid obesity
  • Unstable patients such as uncontrolled hypertension, decompensated heart disease
  • The patient's intraoperative intra-abdominal pressure value is operated with a difference from the pressure determined due to optimal surgical conditions or the patient's lungs do not tolerate it, or switching to open surgery (laparotomy) for any reason.
