Summary We performed a prospective, randomised, double blind study to compare the antishivering effect of morphine and pethidine when added to intrathecal hyperbaric bupivacaine during elective Caesarean delivery under combined‐spinal epidural anaesthesia. Spinal anaesthesia consisted of either 8–10 mg of 0.5% bupivacaine alone (group B; n = 30) with 0.1 mg morphine (group BM0.1; n = 29), with 0.2 mg morphine ( group BM0.2; n = 30), or with 10 mg pethidine (group BPeth10; n = 30). The incidences of shivering were 23.3% (7/30) in group B, 17% (5/29) in group BM0.1, 13.3% (4/30) in group BM0.2 and 3.3% (1/30) in group BPeth10 (p < 0.05). The shivering intensity for each patient was significantly higher in group B than the other groups. In conclusion, intrathecal pethidine added to hyperbaric bupivacaine reduces the incidence and intensity of shivering more than does morphine (0.1 or 0.2 mg).
