Primary |
Dynamic compliance of the ventilator-side lung during 30 minutes of one-lung ventilation during operation |
The respiratory parameters displayed on the anesthesia ventilator screen during 30 minutes of one-lung ventilation during operation were recorded. The formula: lung compliance = tidal volume/platform pressure (Pplat) - positive end expiratory pressure (PEEP) was used to calculate the compliance of the ventilate lung during 30 minutes of one-lung ventilation during operation |
During the operation, the patient was ventilated on one lung for 30 minutes |
|
Secondary |
Lung compliance during double lung ventilation during operation |
The respiratory parameters displayed on the anesthesia ventilator screen during the operation were recorded, and the lung compliance during double-lung ventilation was calculated by the formula: lung compliance = tidal volume/(plateau pressure - positive end-expiratory pressure) |
At the beginning of double lung ventilation during operation; During the operation, the return from one-lung ventilation to double lung ventilation; At the end of the operation |
|
Secondary |
Compliance of the ventilator-side lung during one-lung ventilation during operation |
The respiratory parameters displayed on the anesthesia ventilator screen during the operation were recorded. The formula: lung compliance = tidal volume/(plateau pressure - positive end-expiratory pressure) was used to calculate the compliance of the ventilate lung during single lung ventilation |
At the beginning of one-lung ventilation during operation; one-lung ventilation for 1 hour during the operation |
|
Secondary |
Blood pressure |
Patient invasive arterial pressure |
Before surgery; during operation(Start of double lung ventilation?starting one-lung ventilation?one-lung ventilation for 30 minutes ?one-lung ventilation for 1 hour ?resume double lung ventilation; At the end of the operation; 30 minutes after operation |
|
Secondary |
Heart rate |
Patient heart rate |
BBefore surgery; during operation(Start of double lung ventilation?starting one-lung ventilation?one-lung ventilation for 30 minutes ?one-lung ventilation for 1 hour ?resume double lung ventilation; At the end of the operation; 30 minutes after operation |
|
Secondary |
Blood gas analysis results |
The patient's arterial blood was collected, and the blood gas analyzer was used to determine the human blood H+ concentration and the gas dissolved in the blood (mainly CO2 and O2) to understand the human respiratory function and acid-base balance. Blood gas analysis results include: PaO2(mmHg), PaCO2(mmHg) |
Before anesthesia induction; Double lung ventilation during operation;one-lung ventilation for 30 minutes during operation; one-lung ventilation for 1 hour during operation; At the end of the operation; 30 minutes after surgery |
|
Secondary |
Serum inflammatory factor levels |
Collect the patient's arterial blood, obtain the upper serum through centrifuge, and return the obtained serum to a third party for detection the levels of inflammatory factors in the serum,such as interleukin-8 (IL?8,pg/mL), interleukin-6 (IL?6,pg/mL) concentration, TNF-a(pg/mL) and so on |
Before anesthesia induction;one-lung ventilation for 30 minutes during operation; one-lung ventilation for 1 hour during operation; 30 minutes after surgery |
|
Secondary |
cognitive function |
"Mini-mental State Examination, MMS" was used to evaluate the cognitive function of the patients. The total score of the scale was 30, with the lowest score being 0 and the highest 30. A normal person's MMSE score is usually between 27 and 30 points. If the score is lower than 27, it is necessary to be alert to the existence of cognitive impairment. At the same time, according to different levels of education, the classification criteria are also different. For example, illiteracy below 17 points, primary school education below 20 points, secondary school education below 22 points, college education below 23 points, are considered to have cognitive impairment. |
The day before surgery;Day one after surgery;day three after surgery |
|
Secondary |
Postoperative nausea and vomiting |
Postoperative nausea and vomiting were evaluated using the "Nausea and Vomiting Numerical Rating Scale", the lowest score being 0 and the highest 10, 0 was no nausea; 1-3 is classified as mild nausea; 4-6 classified as moderate nausea; In addition, regardless of the degree of nausea, patients should also record whether they are accompanied by vomiting. If they are accompanied by vomiting, select Yes; Not accompanied by vomiting Select No. |
6 hours postoperatively, 24 hours postoperatively, and 48 hours postoperatively |
|
Secondary |
Depression and anxiety |
The Hospital Anxiety and Depression Scale (HAD) was used to assess the degree of anxiety and depression symptoms. The lowest score is 0 and the highest score is 42. A score of 0-7 is considered normal, a score of 8-10 is suspected of anxiety and depression, and a score of 11-21 is certain of anxiety and depression. In the evaluation, =8 points were positive |
The day before surgery; Day two after surgery |
|
Secondary |
Postoperative pain |
The patients' postoperative pain was evaluated using the "Pain Numerical Rating Scale", the lowest score was 0, the highest score was 10, 0 indicates no pain; A 10 is the worst pain imaginable. A score of 1 to 3 indicates mild pain that does not affect sleep; A score of 4 to 6 indicates moderate pain and disturbed sleep. A score of 7 to 10 indicates severe pain that severely interferes with sleep |
6 hours postoperatively, 24 hours postoperatively, and 48 hours postoperatively |
