Summary

Chronic pain, functional impairment and slow rates of recovery are key issues for patients after surgery and trauma. No preventative strategy in current use unequivocally modifies these rates, and few novel approaches have been tested. Furthermore, persistent postsurgical pain is a major route to chronic opioid use, opioid use disorder and, regrettably, opioid overdose. Most strategies designed to limit chronic pain or enhance functional recovery after surgery are directed at modulating peripheral and central nervous system activity and do not strongly modify the underlying tissue pathophysiology or fundamental systemic responses. Strategies limiting oxidative stress in the perioperative period, on the other hand, might limit tissue damage, organ dysfunction and immune system activation.

N-acetyl cysteine (NAC) is an antioxidant well-studied in the perioperative period; it is very safe, relatively inexpensive and widely available. The central hypothesis is, therefore, that perioperative administration of NAC will reduce perioperative oxidative stress, limit immune system activation and improve key indices of surgical recovery. Although the planned work will not comprehensively address this hypothesis, it will identify the most useful tools and help the researchers estimate the required sample sizes for more definitive externally funded efforts.

Conditions

  • Surgical Recovery
  • Pain, Postoperative

Interventions

DRUG

N-acetyl cysteine

Intravenous infusion started during the clinically indicated surgery at a rate of 50mg/kg over 1 hour followed by 50mg/kg over 3 hours. This will be an accumulated total of 100 mg/kg over 4 hours.

OTHER

Normal Saline

Intravenous infusion at a time and rate to mimic the active treatment. The infusion will be given over 4 hours beginning during the clinically indicated surgery
