Dear Friends,


I noticed that there are no records in the clinical sources regarding the type of anesthetics used during surgery. As my research may be impacted by the use of a ventilator, I need to determine whether the patient was on mechanical ventilation during anesthesia.

To identify ventilator usage, I plan to use Sevoflurane or Desflurane administration as a proxy. Therefore, I kindly request that you provide me with data on the usage of these anesthetics during surgery.

I would greatly appreciate any information you can provide, as it could have a significant impact on the accuracy of my research.

Thank you for your attention to this matter, and I look forward to hearing from you soon.


Best regards,

Dear Friends,

Thank you very much for your response. I would like to confirm the following based on the information you provided:

There are a total of 3,733 patients who used Sevoflurane in the Data Viewer page. There are 2,156 patients who used Desflurane. Among them, there are 710 patients who used both Sevoflurane and Desflurane. Therefore, the total number of patients who used any type of "flurane" is 3,733 + 2,156 - 710 = 5,179. Hence, it can be inferred that there are a total of 5,179 patients who used a ventilator. The remaining 6,388 - 5,179 = 1,209 patients are considered non-ventilator users.

General Thoracic Gynecology Urology Total
Sevoflurane 2,076 (42.1%) 255 (23.0%) 172 (74.8%) 34 (29.1%) 2,537 (39.7%)
Desflurane 1,012 (20.5%) 226 (20.3%) 69 (30.0%) 106 (90.6%) 1,383 (21.6%)
Propofol 2,490 (50.5%) 996 (89.6%) 5 (2.2%) 7 (6.0%) 3,498 (54.8%)
Remifentanil 3,639 (73.8%) 1,000 (90.0%) 110 (47.8%) 86 (73.5%) 4,835 (75.7%)

However, there seems to be some discrepancy with the information provided in the VitalDB Overview. Could you please clarify if I have misunderstood something?
I apologize for any inconvenience caused by my lack of medical background.

Thank you for your attention to this matter, and I look forward to hearing from you soon.
