Ketamine-pancuronium-narcotic technic for cardiovascular surgery in infants--a comparative study

Area of Science:

• Cardiovascular Surgery
• Anesthesiology
• Pediatric Critical Care

Background:

• Infant cardiovascular surgery requires careful anesthetic management.
• Previous anesthetic techniques carried significant risks.
• Novel anesthetic combinations are explored to improve outcomes.

Purpose of the Study:

• To compare the efficacy and safety of ketamine-pancuronium-narcotic (KPN) anesthesia with a historical anesthetic technique (d-tubocurarine, halothane, and/or N2O-O2) in infants undergoing cardiovascular operations.
• To evaluate hemodynamic stability, incidence of ventricular fibrillation, and short-term mortality between the two anesthetic groups.

Main Methods:

• Retrospective analysis of 71 infants undergoing cardiovascular operations over a 1-year period using KPN anesthesia.
• Comparison with a similar cohort of patients anesthetized 3 years prior with d-tubocurarine, halothane, and/or N2O-O2.
• Assessment of circulatory system stability, adverse cardiovascular events, and 48-hour mortality.

Main Results:

• The KPN anesthetic technique provided good circulatory stability during the induction phase.
• However, significant hypotension/bradycardia, ventricular fibrillation, and 48-hour mortality rates were similar between the KPN group and the historical anesthetic group.
• The KPN technique did not show a significant advantage over the older method once surgical dissection commenced.

Conclusions:

• Despite claims of minimal cardiovascular adverse effects, the ketamine-pancuronium-narcotic anesthetic technique was not superior to the traditional halothane-N2O-O2-curare technique for infant cardiovascular surgery.
• Both anesthetic regimens resulted in comparable outcomes regarding hemodynamic stability, major adverse events, and short-term survival.
• Further research may be needed to identify optimal anesthetic strategies for complex pediatric cardiac procedures.
