Sažetak

Tramadol is a commonly used analgesic in intensive care units (ICUs) for acute
postoperative pain. Conversion of tramadol into active metabolites may be impaired in inflammatory
states. Catechol-O-methyltransferase may influence pain. The aim of the study was to examine differences
in the analgesic effect of tramadol between ICU patients with and without signs of systemic
inflammation. Forty-three patients were admitted to ICU after a major abdominal surgery. The patients
received a dose of 100 mg of tramadol intravenously every 6 hours during the first 24 hours
after surgical procedure. Pain scores were measured by the Numeric Rating Scale before and 30
minutes
after tramadol administration in awake patients. Systemic inflammation was considered
when at least two of the following postoperative parameters were present in the first 24 hours of ICU
admission: fever or hypothermia, tachycardia, pCO2 <4.3 kPa, white blood cells >12000/mm3 or
<4000/mm3, or preoperative value of C-reactive protein (CRP) >50 mg/L or/and procalcitonin (PCT)
>0.5 mg/L. Catechol-O-methyltransferase was analyzed postoperatively. Fifteen (34.8%) patients
met the criteria for systemic inflammation. Tramadol was proven to be an effective analgesic for the
treatment of postoperative pain regardless of the presence of systemic inflammation (p<0.05). Lower
perception of pain before tramadol application was observed in patients with systemic inflammation,
but the difference was not significant. A negative correlation was observed between the preoperative
values of CRP and PCT and the analgesic effect of tramadol assessed at the second measurement
point (r=-0.358, p=0.03, and r=-0.364, p=0.02, respectively). Catechol-O-methyltransferase variants
were not in correlation with pain and opioid consumption. Based on our findings, tramadol is effective
in lowering pain scores after major abdominal surgery irrespective of the presence of systemic inflammation.
