All the parturients received intrathecal injection of a solution containing 150 mug morphine or normal saline in addition to 10-12 mg hyperbaric bupivacaine 0.5%. In both groups, a significant decrease in body temperature was noted. There was no difference in the area under the curve for temperature against time for the two groups; however, the maximum decrease in temperature from baseline was significantly larger after morphine than after saline injection (mean (SD) 1.11 (0.61) degrees C vs 0.76 (0.39) degrees C, respectively; p = 0.01) and the time to nadir temperature was significantly longer (59.5 (17.6) min vs 50. 4 (15.9) min, respectively; p = 0.047). The lowest temperature observed in the morphine group was 34.3 degrees C. We conclude that intrathecal injection of 150 microg morphine intensified the intra-operative hypothermic effect of bupivacaine spinal anaesthesia for caesarean section.en-USSUBARACHNOID MORPHINEAnalgesics, Opioid/adverse effectsAnesthesia, Obstetrical/ adverse effects/methodsAnesthesia, Spinal/ adverse effects/methodsAnesthetics, Local/ adverse effectsArea Under Curve
