Analgesic efficacy and safety of single-dose intramuscular ketorolac for postoperative pain management in children following tonsillectomy
& NA ; The efficacy of ketorolac , a non‐steroidal anti‐inflammatory drug , in the management of moderate to severe pain in adults , has led us to conduct a trial of this analgesic in children following tonsillectomy . Children were r and omized to receive intramuscular ( i.m . ) ketorolac ( 1 mg/kg , EXP group , n = 45 ) or saline ( CTL group , n = 42 ) at the completion of surgery . Intravenous ( i.v . ) fentanyl ( 0.5 & mgr;g/kg/dose ) was administered in repeated doses postoperatively . Pain intensity was measured using both the Oucher and the Children 's Hospital of Eastern Ontario Pain Scale ( CHEOPS ) to allow for comparison between self‐report and behavioral measures of pain intensity . Severity of postoperative bleeding was measured using a 4‐point rating scale . The EXP group had a significant reduction in total fentanyl dose ( mean : 35.9 & mgr;g ) compared to the CTL group ( mean : 48.3 & mgr;g , t = −2.21 , P < 0.03 ) . There was a statistically significant decrease in pre‐fentanyl CHEOPS scores in the Post‐Anesthesia Care Unit ( PACU ) in the ketorolac group ( F ( 2,30 ) = 5.34 , P < 0.01 ) , but not in the saline group ( F ( 2.24 ) = 2.46 , P > 0.05 ) . In the first hour postoperatively , the CHEOPS demonstrated significant decreases in pain intensity scores in response to opioids , in both groups . In the PACU , children were unable to provide a self‐report of pain intensity potentially due to a variety of factors ( e.g. , emergence delirium , agitation , excitement , sedation , and /or pain ) . However , during the remainder of the postoperative stay , the photographic scale of the Oucher was a more valid measure of pain intensity than the CHEOPS . There were no differences between the 2 groups in the severity of postoperative bleeding . Children in the EXP group were discharged significantly earlier ( i.e. , 30 min , t = −2.22 , P < 0.03 ) . Our data demonstrate that i.m . administration of ketorolac , at the end of surgery , significantly reduces opioid requirements and shortens length of stay without any evidence of increased bleeding . In addition , our data suggest that the patient 's altered level of consciousness and attention span may diminish the utility of self‐report measures of  pain intensity  in the immediate postoperative period
