Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The amount of brain oxygen of patients. Timepoint: In the awake state (T0), 5 minutes after induction of anesthesia and intubation before Blowing gas into the abdomen (T1) and then 5 minutes after blowing gas into the abdomen (T2), 15 minutes after blowing gas into the abdomen (T3), immediately after gas exit and changing the horizontal position (T5) And it will be recorded 15 minutes after the exit of gas (T6). Method of measurement: It will be measured based on the cerebral oxygenation percentage listed in the patient's monitoring.;Systolic, diastolic and mean arterial blood pressure. Timepoint: In the awake state (T0), 5 minutes after induction of anesthesia and intubation before Blowing gas into the abdomen (T1) and then 5 minutes after blowing gas into the abdomen (T2), 15 minutes after blowing gas into the abdomen (T3), immediately after gas exit and changing the horizontal position (T5) And it will be recorded 15 minutes after the exit of gas (T6). Method of measurement: Based on the blood pressure listed in the patient's monitoring, it will be measured in millimeters of mercury.;The patient's heart rate. Timepoint: In the awake state (T0), 5 minutes after induction of anesthesia and intubation before blowing gas into the abdomen (T1) and then 5 minutes after blowing gas into the abdomen (T2), 15 minutes after blowing gas into the abdomen Abdomen (T3) will be recorded immediately after passing gas and changing the horizontal position (T5) and 15 minutes after passing gas (T6). Method of measurement: It will be measured based on the number of beats listed in the patient's monitoring based on the number of heart beats per minute.;Oxygen saturation of arterial blood of patients. Timepoint: In the awake state (T0), 5 minutes after induction of anesthesia and intubation before blowing gas into the abdomen (T1) and then 5 minutes after blowing gas into the abdomen (T2), 15 minutes after blowing gas into the abdomen Abdomen (T3) will be recorded immediately after pa | — |
Secondary
| Measure | Time frame |
|---|---|
| Investigation of complications and outcome of patients in recovery in two groups of high intra-abdominal pressure (13-15 mm Hg) and low intra-abdominal pressure (10-12 mm Hg). Timepoint: After surgery. Method of measurement: The presence of nausea, vomiting/hemorrhage/pneumothorax/loss of saturation/increase or decrease in blood pressure will be measured in patients.;Satisfaction of the surgeon. Timepoint: After surgery. Method of measurement: Based on the 5-point Likert scale, it will be measured as very poor/poor/satisfactory/good/excellent. | — |
