Lornoxicam with Low-Dose Ketamine versus Pethidine to Control Pain of Acute Renal Colic

This study was established to compare single-dose lornoxicam 8 mg (NSAID) in addition to 0.15 mg.kg^-1 ketamine with single-dose pethidine 50 mg, both administered intravenously (IV), on the quickness and extent of analgesia, disadvantage, and consequence on utilitarian situation.

One hundred and twenty patients with acute renal colic pain received in emergency room were included in this prospective, randomized, and double blind clinical study. They were aimlessly designated into one of two groups using a computer-generated table. Group L received lornoxicam 8 mg IV plus 0.15 mg.kg^-1 ketamine and Group P received pethidine 50 mg IV. Parameters were noticed at baseline and after 0, 15, 30, and 45 minutes and 1 hour after drug administration. The efficiency of the drug was determined by observing: patient rated pain, time to pain relief, rate of pain recurrence, the need for rescue analgesia, adverse events, and functional status.

The visual analogue scale was significantly lower in Group L after 30 minutes in comparison to Group P. In addition, there was statistically significant increase in Group P regarding their need for rescue analgesia after 30 min in comparison to Group L. Group P showed nonsignificantly increased sedation score compared to Group L.

Patients receiving lornoxicam-ketamine attained greater reduction in pain scores and less side effects with better functional state and also are less likely to require further analgesia than those administered pethidine to control acute renal colic pain.
