Propofol infusion anesthesia is effective for thoracic surgery. Adding nitrous oxide reduces propofol needs but may delay recovery of spontaneous breathing in patients undergoing surgery.

Area of Science:

  • Anesthesiology
  • Thoracic Surgery
  • Intravenous Anesthesia

Background:

  • Propofol is a common intravenous anesthetic agent.
  • Thoracic surgery requires careful anesthetic management.
  • Evaluating anesthetic techniques is crucial for patient outcomes.

Purpose of the Study:

  • To assess the efficacy and safety of propofol infusion for thoracic surgery.
  • To compare propofol requirements with and without nitrous oxide supplementation.
  • To evaluate the impact of nitrous oxide on anesthetic induction and recovery.

Main Methods:

  • 100 patients undergoing elective thoracic surgery were included.
  • Anesthesia was induced and maintained with propofol continuous intravenous infusion.
  • 60 patients received nitrous oxide supplementation with air-oxygen or nitrous oxide-oxygen mixtures.

Main Results:

  • Propofol infusion anesthesia was satisfactory for thoracic surgery.
  • Anesthesia induction with propofol caused significant blood pressure decreases.
  • Nitrous oxide significantly reduced propofol requirements (P < 0.01) but prolonged recovery time to the first spontaneous breath.

Conclusions:

  • Propofol infusion is a viable intravenous anesthetic technique for thoracic surgery.
  • Nitrous oxide supplementation can decrease propofol dosage but may delay respiratory recovery.
  • This anesthetic approach offers a satisfactory alternative for select surgical patients.
