Surgery: An Integrative Approach

Are you a health professional?

This section does not replicate the other information on this page but provides additional details or context most relevant to professionals.

Clinical practice guideline

Topics addressed included perioperative screening, postponement of elective surgery, concomitant use of opioid and cannabis perioperatively, implications for parturients, adjustment in anesthetic and analgesics intraoperatively, postoperative monitoring, cannabis use disorder, and postoperative concerns. Surgical patients using cannabinoids are at potential increased risk for negative perioperative outcomes.

More information: Enhanced recovery after surgery (ERAS)

Enhanced recovery after surgery (ERAS) is a multimodal, multidisciplinary approach to the care of the surgical patient. Implementation involves a team of surgeons, anesthetists, an ERAS coordinator (often a nurse or a physician assistant), and staff from units that care for the surgical patient.

ERAS protocols are designed to achieve early recovery after surgical procedures by maintaining pre-operative organ function and reducing the profound stress response following surgery. Key elements of ERAS protocols:¹Melnyk M, Casey RG, Black P, Koupparis AJ. Enhanced recovery after surgery (ERAS) protocols: time to change practice? Canadian Urological Association Journal. 2011;5(5):342-348.

Immunonutrition

Immunonutrition involves using specific nutrients to influence the activity of the immune system. Arginine, glutamine, branched chain amino acids, omega-3 fatty acids, and nucleotides have been studied most often.²Calder PC. Immunonutrition in surgical and critically ill patients. British Journal of Nutrition. 2007;98 Suppl 1:S133-S139. 

• Substantially fewer infections and infectious complications but no evidence of an effect on 30-day mortality after elective curative surgery for a solid malignant tumor among people treated with immunonutrition orally before surgery (and some continuing after surgery) compared to controls not receiving immunonutrition in a meta-analysisa statistical analysis that combines the results of two or more research studies; the results of smaller research studies addressing the same or similar questions can be analyzed as though they are one bigger, more powerful study of 22 RCTsrandomized controlled trial, a study design in which people are randomly assigned to either an experimental group or a control group to compare the outcomes from different treatments; an RCT is considered a strong design for determining a therapy’s effects³Buzquurz F, Bojesen RD, Grube C, Madsen MT, Gögenur I.
