Brief summary
Comparison of preoperative folic acid and VitB12 intervention on postoperative delirium and long-term neurobehavioral changes in children under general anesthesia
Detailed description
Folic acid, as a one-carbon unit transferase coenzyme, participates in the synthesis of purine and thymine, and is an important element of the nervous system. Vitamin B12 participates in methyl conversion and folate metabolism in the body, promoting the conversion of 5-methyltetrahydrofolate to tetrahydrofolate. It has been reported that the lack of serum folic acid and B12 is associated with an increased risk of cognitive impairment. The explanation mechanism of the relationship between folic acid deficiency and cognitive dysfunction may be that folic acid deficiency leads to impaired central nervous system methylation, resulting in insufficient methyl synthesis of myelin sheaths, neurotransmitters, membrane phospholipids and deoxyribonucleic acid. Our previous studies showed that preoperative folic acid supplementation can alleviate myelin damage and cognitive impairment in young rats caused by sevoflurane anesthesia. Therefore, this study further explored the preoperative folic acid and coenzyme B12 supplementation for children's delirium and long-term neurobehavioral changes after general anesthesia.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| PAED scale | 10 minutes after surgery | Observe whether the index will cause delirium during the recovery period.The evaluation range of the PAED scale is 0-20 points, If the score exceeds 10 points, Then it is considered delirium. |
| Gesell scale | 2 day after surgery | Through the gesell scale, 5 tests are carried out on children: gross motor ability, fine movement, physical ability, verbal ability, and human ability.The evaluation range of the Gesell scale is 0-100 points. If the score is higher, it means good. If the score is low, it means that the result is not good. If the result is not good, it may be caused by anesthesia, so we conducted this evaluation. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Extubation time | immediately after surgery | Extubation time |
| Ramsay sedation score | 10 minutes after extubation | Ramsay sedation score after recovery, extubation and every 10min within 30min after extubation，Ramsay sedation score is 1-6 points. If the score is 2-4 points，That result is satisfactory, 5-6 points are excessive sedation. |
| Postoperative pain CHEOPs scores | 20 minutes after extubation | The postoperative pain CHEOPs scores were taken at the time of extubation and every 10 minutes within 30 minutes after extubation (the total score was less than 6 points, there was no pain, and ≥10 points for corresponding analgesia treatment). The total score is 46 points, if the total score is less than 6 points, it is judged as no pain |
| Heart Rate | During the induction period of anesthesia, intubation, and the operation period；immediately after entering the resuscitation room (T1), 5 minutes before extubation (T2), immediately after extubation (T3), and 2 minutes after extubation (T4); | Observe heart rate through a monitor |
| Other adverse events during the recovery period | Immediately after the surgery | Other adverse events during the recovery period (eg nausea and vomiting, bronchospasm, respiratory depression, etc.) |
| recovery time | immediately after recovery | recovery time |
| Narcotic drugs | During the surgery | The use of narcotic drugs (eg pentazocine, propofol) |
| Mean Blood Pressure | During the induction period of anesthesia, intubation, and the operation period；immediately after entering the resuscitation room (T1), 5 minutes before extubation (T2), immediately after extubation (T3), and 2 minutes after extubation (T4); | Observe and calculated mean blood pressure through a monitor |
