Total spinal anesthesia for cardiac surgery: does it make a difference in patient outcomes?

Area of Science:

• Anesthesiology
• Cardiac Surgery
• Critical Care Nursing

Background:

• Cardiac surgery poses significant physiological stress, potentially leading to adverse patient outcomes.
• A novel anesthetic technique, combining spinal anesthesia with intrathecal morphine and general anesthesia (TSA), aims to mitigate this stress response.
• Understanding the impact of TSA on patient recovery is crucial for optimizing perioperative care.

Purpose of the Study:

• To compare the outcomes of TSA cardiac surgery with standard general anesthesia (GA) in a pilot study.
• To describe the effects of TSA on key postoperative recovery metrics.
• To provide a basis for future research on TSA in cardiac surgery patients.

Main Methods:

• Retrospective, descriptive, correlational design.
• Matched pair analysis of 70 patients (35 TSA, 35 GA).
• Data collected via chart review following ethics approval and patient consent.

Main Results:

• TSA patients were significantly more likely to be extubated in the operating room (p < 0.0001).
• TSA group demonstrated significantly shorter endotracheal intubation duration (p < 0.0008) and reduced morphine use (p < 0.0001) in the first 24 hours.
• While not statistically significant, TSA patients were discharged an average of three days earlier than GA patients.

Conclusions:

• Anesthetic technique significantly impacts postoperative care and outcomes in cardiac surgery.
• Findings support the clinical relevance of TSA for critical care nursing and multidisciplinary teams.
• This pilot study provides rationale for larger prospective research on TSA in cardiac surgery.
