| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Patients without preoperative education by anesthesiologists | No Intervention | Patients get minimal information about the surgical process and their questions will be answered by obstetrician. | |
| Patients with preoperative education by anesthesiologists | Experimental | Patients get preemptive education about the whole process from anesthesia to recovery stage within 15 minute by anesthesiologists. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| preemptive education provided by anesthesiologists | Behavioral | A preemptive education about 4 stages (prepare, anethesia, surgery, and recovery) by anesthesiologists within 15 minute. |
| Measure | Description | Time Frame |
|---|---|---|
| Number of participants with intraoperative maternal shivering | Record when shivering occurred within the time frame | From the moment the patient enters the operating room (0 minute) until leaving the operating room on the same day, expected to be up to 180 minutes. |
| Measure | Description | Time Frame |
|---|---|---|
| Intraoperative body temperature | 0, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180 minutes after entering the operating room until the end of surgery. | |
| Intraoperative pain (Numeric rating scale, NRS). | NRS 0: no pain 1-3: mild pain (nagging, annoying, interfering little with acitivities of daily living (ADLs)) 4-6: moderate Pain (interferes significantly with ADLs) 7-10: severe Pain (disabling; unable to perform ADLs) Record when the patient complained pain within the time frame |

| From the moment the patient enters the operating room (0 minute) until leaving the operating room on the same day, expected to be up to 180 minutes. |
| Spinal anesthesia level (dermatome) | From the intrathecal injection (0 minute) until at the end of surgery (0, 5, 10, 25, 40, 55, 75 minute, at the end of surgery) |
| Post-operative spinal anesthesia level in recovery room | The level(dermatome) of spinal anesthesia will be checked by pin-prick test by an anesthesiologist or nurse. | From the time the patient enters the recovery room (0 minute) until leaving the recovery room (0, 15, 30, 45 minute, at the time the patient leaves the recovery room) |
| Number of Participants with Post-operative shivering in recovery room | From the time the patient enters the recovery room (0 minute) until leaving the recovery room (0, 15, 30, 45 minute, at the time the patient leaves the recovery room) |
| Post-operative body temperature in recovery room | From the time the patient enters the recovery room (0 minute) until leaving the recovery room (0, 15, 30, 45 minute, at the time the patient leaves the recovery room) |
| Post-operative nausea and vomiting in recovery room (by questionnaire) | Nausea and vomiting will be assessed by questionnaire. (yes/no) | From the time the patient enters the recovery room (0 minute) until leaving the recovery room (0, 15, 30, 45 minute, at the time the patient leaves the recovery room) |
| Patient's satisfaction by questionnaire | Patient's satisfaction about pre-operative preparation, anesthesia, and surgery by questionnaire. Participants will respond their satisfaction by score 0-10. (A higher score means higher satisfaction. ) | From the end of surgery until 24 hours after surgery |
| Pain (assessed by NRS) until post-operative day 1 | NRS (numeric rating scale) is detailed at Outcome number 3. | At 6, 12, 18, 24 hours after the end of surgery |
| Analgesic dosage (Morphile miligram equivalents) until post-operative day 1 | From the end of surgery until 24 hours after surgery |
| Obstetric quality of recovery until post-operative day 1 | Quality of recovery will be assessed by Obstetric Quality of Recovery-11K survery, which is a questionnaire completed by participants. Higher score means higher quality of recovery. | At 24 hours after surgery |
