| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Residual volume of gastric contents following induction of general anaesthesia | Approximately 5-10 minutes following the induction of general anaesthesia. | Gastric volume and pH of that fluid that can be aspirated via an oro-gastric tube, passed into the patient's stomach once general anaesthesia has been induced and the airway secured. |
| Primary | pH of gastric contents following induction of general anaesthesia | Approximately 5-10 minutes following the induction of general anaesthesia. | Gastric volume and pH of that fluid that can be aspirated via an oro-gastric tube, passed into the patient's stomach once general anaesthesia has been induced and the airway secured. |
| Other | Adverse events at induction of anaesthesia | Up to 10 minutes after the induction of anaesthesia | Adverse events occurring around the time of induction of anaesthesia including regurgitation and aspiration of gastric contents |
| Other | Adverse events at emergence from anaesthesia | Up to 10 minutes from removal of the patient's airway | Adverse events occurring around the time of emergence from anaesthesia including regurgitation and aspiration of gastric contents |
| Other | Paracetamol drug errors | For day case patients, until discharge. For inpatients, up to 24 hours post-operatively. | Paracetamol related drug errors |
| Other | Emergence delirium | Up to 10 minutes following patient arrival in PACU. | Incidence of emergence delirium in post-anaesthesia care unit, measured with PAED score. |
| Other | Adverse events in Post-Anaesthesia Care Unit | From arrival in the post-anaesthesia care unit until patient is ready for discharge to the ward, up to 24 hours. | Adverse regurgitation or aspiration events occurring in the post-anaesthesia care unit, including requirements for additional analgesia, time to first analgesic request and time spent in the post-anaesthesia care unit. |
