Clinical efficacy of morphine combined with phloroglucinol in the treatment of renal colic

Abstract

Objective To evaluate the efficacy of multiple injection of morphine combined with phloroglucinol in the treatment of renal colic. Methods One hundred and twenty patients with severe renal colic were equally divided into three groups by random digits table,with 40 cases each group. The group A was administrated with physiological saline 100 ml and phloroglucinol 80 mg intervenous drop infusion combined with morphine 9 mg intravenous injection fractionated into three times, and the group B was administrated with physiological saline 100 ml and phloroglucinol 80 mg intervenous drop infusion,and the group C was administrated with physiological saline 100 ml intervenous drop infusion and morphine 9 mg intravenous injection fractionated into three times. At 10,20 and 40 min after administration, the antalgic efficacy of three groups were analyzed as well as the side effect. Results At 20 min and 40 min both of the total efficacy rates in group A[82.5%(33/40),95.0%(38/40)] were higher than those in group B [62.5%(25/40),80.0%(32/40)] and group C [60.0%(24/40),77.5%(31/40)] (P＜ 0.05),and the colic-exclusion rate in group A was also higher than that in group B and group C (P ＜ 0.05). The difference of the efficacy rates in group A in these two time-points had no statistical significance (P ＞0.05). No increased pain occurred in group A except 1 case of vomiting. Conclusion Multiple injection of morphine combined with phloroglucinol is quick, effective and safe in the early treatment of renal colic. Key words: Nephrosis; Colic; Morphine; Phloroglucinol
