Table 1 Classification system for cardiac arrest [4]
From: A study of anaesthesia-related cardiac arrest from a Chinese tertiary hospital
Group | Definition |
|---|---|
Anaesthesia-related | Where it is reasonably certain that CA was caused by the anaesthesia or other factors under the control of the anaesthetist |
Anaesthesia-contributing | 1. Where there is some doubt whether CA was entirely attributable to the anaesthesia or other factors under the control of the anaesthetist 2. Where CA was caused by both surgical and anaesthesia factors |
Unrelated to anaesthesia | 1. CA where the administration of the anaesthesia did not contribute and surgical or other factors are implicated 2. Inevitable CA, which would have occurred irrespective of anaesthesia or surgical procedures 3. Incidental CA, which could not reasonably be expected to have been foreseen by those looking after the patient, was not related to the indication for surgery and was not due to factors under the control of the anaesthetist or surgeon. 4. Those that cannot be assessed despite considerable data but where the information is conflicting or key data are missing 5. Cases that cannot be assessed because of inadequate data |
