Brief summary
The primary aim of this interventional study is to investigate the impact of perioperative administration of Maxigesic (combination of acetaminophen and ibuprofen) on delirium after minimally invasive lung surgery in elderly patients. The Maxigesic group receives a total of 5 doses of Maxigesic (20mg/kg, maximum dose per serving: 1g) every 6 h from immediately after anesthesia induction. The control group receives the same volume of normal saline. Researchers compare the incidence and severity of postoperative delirium for 5 days after surgery.
Interventions
Patients in the Maxigesic group will be administered a total of 5 doses of the drug (20mg/kg, maximum dose per serving: 1g) every 6 h from immediately after anesthetic induction.
Patients in the control group will be administered equal amounts of normal saline at the same time points.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of postoperative delirium(POD) | From immediately after surgery to 5 days after surgery | Confusion assessment method(CAM)/Confusion Assessment Method for the ICU (CAM-ICU) or delirium record on electrical medical record(EMR) will be used for the evaluation of POD. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Severity of POD | From immediately after surgery to 5 days after surgery | CAM-S(severity) will be utilized to assess the severity of POD. (\*CAM-S is measured on 0-7 (short form) and 0-19 (long form) scale, and the higher the score, the greater the POD severity.) |
| Duration of POD | From immediately after surgery to 5 days after surgery | CAM/CAM-ICU or delirium record on EMR will be used to estimate the duration of POD. |
| Preoperative cognition | 1 day before surgery | Mini-mental state examination(MMSE) will be used to evaluate the participants' preoperative cognition. (\*MMSE is measured on 0-30 scale, and the lower the score, the more cognitively impaired the patient is.) |
| Preoperative frailty | 1 day before surgery | Clinical frailty scale(CFS) will be utilized to assess the preoperative frailty (\*CFS is used to determine comprehensive geriatric assessment. It is measured on 1-9 scale, and the higher the scale, the more frail the patient is.) |
| Postoperative pain | Immediately after surgery to postoperative 48 hours | Numerical rating scale (NRS) or Visual analogue scale (VAS) will be used to determine the postoperative pain severity (\*NRS and VAS are measured on a 0-10 scale, and the higher the score, the more severe the patient's pain. If the patient can verbalize their pain, use the NRS; otherwise, use the VAS to assess pain). |
| ICU stay | Immediately after surgery to ICU discharge(usually within about 5 days after surgery) | Determine how many days the participant stays in the ICU. |
| Postoperative nausea, vomiting | Immediately after surgery to postoperative 48 hours | Nausea is measured by scoring on a scale of 0-10. The higher the score, the more severe the symptom. Whether the patients vomit or not is observed and recorded. |
| Hospital stay | Immediately after surgery to hospital discharge(usually within about 30 days after surgery) | Determine how many days the participant stays in the hospital. |
| Postoperative complications | Immediately after surgery to hospital discharge(usually within about 30 days after surgery) | Investigate all kinds of complications that occur after surgery. |
| Drug side effects | Immediately after surgery to hospital discharge(usually within about 30 days after surgery) | Investigate complications suspected to be side effects caused by the study drug. |
| Consumption of opioids | Immediately after surgery to postoperative 48 hours | Opioid consumption is measured by converting them into morphine equivalents. |
