NCT06421688

Brief Summary

The goal of this clinical trial is to investigate the effect of perioperative administration of vitamin C on postoperative pulmonary complications, with the aim of providing a safe and effective medication regimen for the prevention and treatment of postoperative pulmonary complications in patients undergoing surgery for craniocerebral tumors. The main questions it aims to answer are:

  1. 1.To determine whether vitamin C can reduce pulmonary complications after surgery for intracranial tumors.
  2. 2.Does intraoperative vitamin C improve the prognosis of surgical patients
  3. 3.Participants will be intravenously pumped with vitamin C for two hours after induction of anesthesia.
  4. 4.Participants will have intraoperative plasma sampling and recording of ventilator parameters, monitor parameters and perioperative data.
  5. 5.Participants will be followed up until discharge from the hospital to record symptoms and adverse events, and will be called at six months to check on their prognosis.

Outcome Measures

Primary Outcomes (1)

  • incidence of postoperative pulmonary complications

    This will be assessed using the Postoperative Pulmonary Complications Score, which ranges from 0 to 5, with a score of ≥3 being considered positive for postoperative pulmonary complications. It was assessed every day before discharge and the highest score that occurred was recorded.

    About 10 days

Secondary Outcomes (12)

  • Neuron-specific enolase levels

    Post operative day 1

  • Length of hospitalization

    About 10 days

  • Oxygenation index

    One hour postoperative

  • Pain scores

    1 day, 3 days, 7 days postoperative

  • pulmonary compliance

    Last hour of surgery.

  • +7 more secondary outcomes

Study Arms (2)

Ascorbic acid group

EXPERIMENTAL

Patients received 50 mg/kg of Ascorbic acid after induction of anesthesia

Drug: Ascorbic acid

Control comparator group

PLACEBO COMPARATOR

Patients receive 50ml saline after induction of anesthesia

Drug: Saline

Interventions

After participants underwent induction of anesthesia, Ascorbic acid (Vitamin C Injection) was administered at a dosage of 50 mg/kg, diluted to 50 ml using saline, with a total amount not exceeding 4 g; pumping was performed using a micro pump at a rate of 25 ml/h.
