About

Research purposes:Comparison of preoperative folic acid and placebo intervention on postoperative recovery of sputum in children undergoing general anesthesia for head and neck and maxillofacial surgery Test type:Randomized, double-blind, placebo-controlled, prospective study Randomized grouping: Patients were randomized into an intervention group (fed for 7 days before surgery) and a placebo group (7 days for placebo) Test subjects: recruitment and sample size calculation, inclusion criteria, exclusion criteria, shedding cases, trial suspension, rejection criteria, trial termination,Test contents Evaluation indicators: main observation indicators, secondary observation indicators Adverse events: definition of adverse events, recording of adverse events, treatment of adverse events, assessment of adverse events, serious adverse events, definition of serious adverse events, recording and reporting of serious adverse events

Full description

According to literature review, the incidence of sputum sputum in children is about 38.8% (Reference 1), and the incidence of sputum sputum in the placebo group is 38%, assuming a class of error probability α = 0.05, test efficiency 1-β=0.8, considering folic acid supplementation for 7 days can reduce the incidence of sputum to 23%. A chi-square test is proposed to assess whether there is a difference in the incidence of sputum between groups. Calculated by PASS software, the sample size was 300. Considering the 5% drop rate, a total of 316 inpatients with head and neck and maxillofacial surgery were included, divided into 2 groups, 158 cases in each group.

The PAED score was scored every 10 minutes during the recovery of the child, at the time of extubation, and within 30 minutes after extubation (total score 0-20, score ≥10 is defined as the recovery period).

8.2 secondary observation indicators:

  1. Changes in induction of anesthesia, intubation, and central rate (HR) and mean blood pressure (MBP);
  2. HR and MBP changes in the resuscitation chamber (T1), 5 min (T2) before extubation, T3 at extubation, and 2 min (T4) after extubation;
  3. extubation time and wake-up time;
  4. Postoperative Ramsay sedation scores were performed every 10 minutes during recovery, at the time of extubation, and within 30 minutes after extubation;
  5. Postoperative pain CHEOPs scores were taken every 10 minutes during extubation and 30 min after extubation (the total score was less than 6 points and no pain was observed, and ≥10 points were treated with corresponding analgesia);
  6. The use of anesthetic drugs (eg, pentazocine, propofol);
  7. Changes of serum IL-6, TNF-α and folic acid concentrations before and after surgery.
  8. Other adverse events during the recovery period (eg nausea and vomiting, bronchospasm, respiratory depression, etc.)

300 participants in 2 patient groups

Intervention group
Experimental group
Description:
Intervention group: patients took 7 days of folic acid tablets before surgery (0.3mg/d for children aged 1-3, 0.4mg/d for children aged 4\~5 years, dissolved in 20ml brown sugar water.)
Treatment:
Drug: Folic Acid
Placebo group
Experimental group
Description:
Placebo group: The patient received the same dose of brown sugar water for 7 days before surgery. Folic acid dose selection is based on the maximum daily intake of children(tolerable upper intake levels,UL)
