Study information
Scientific title
Perioperative glutamine administration: a potential therapy for preventing post-operative immune hypo-responsiveness
Acronym
Study hypothesis
Intravenous administration of glutamine before, during and after major operations counteracts the immune hypo-responsiveness that follows major surgery.

Condition
Post-operative immune hypoparesis in children undergoing major surgery
Intervention
Perioperative intravenous glutamine infusion versus isonitrogenous infusion
Intervention type
Drug
Phase
Not Specified
Drug names
Glutamine
Primary outcome measure
HLA DR expression by monocytes, and exvivo production of tumour necrosis factor (TNF) alpha following lipopolysaccharide stimulation
Secondary outcome measures
Since glutamine has been shown to influence phagocytic activity we will measure postoperative changes in ß2 integrin expression and activation, internalization and killing of bacteria and respiratory burst, and circulating pro- and anti-inflammatory cytokines. The endocrine/metabolic response to surgery will be assessed by measuring plasma insulin, cortisol, catecholamines, glucose, lactate and free-radical production (malondialdehyde, nitrate/nitrite). In addition the following clinical variables will be recorded: operative complications (e.g. bleeding, intestinal perforation); early postoperative complications (e.g. wound infection, abscess formation, leakage of intestinal anastomosis, evidence of systemic inflammatory response syndrome [SIRS], positive blood culture, bronchopneumonia, urinary tract infection); duration of mechanical ventilation; length of stay in intensive care unit; duration of inotropic requirement; time to full enteral feeding and duration of hospital stay.
