Objective To compare the analgesic effects of epidural Morphine versus lumbosacral plexus block in patients undergoing hip joint replacement.Methods A total of 94 ASA Ⅰ ~ Ⅱpatients undergoing hip surgery with combined spinal epidural anesthesia(CSEA) were selected and randomized into 4 groups:Group M received a single epidural injection of 2 mg Morphine for analgesia,Group MN1 received an epidural injection of 1 mg Morphine combined with lumbosacral plexus block,Group MN2 received an epidural injection of 2 mg morphine combined with lumbosacral plexus block,and Group N received lumbosacral plexus block.All patients were administered intramuscular parecoxib for 3 days after surgery and,if the visual analogue scale(VAS)≥4,additional intramuscular tramadol.Patient-controlled intravenous analgesia(PCIA) was applied if pain relief was insufficient after Tramadol treatment.Postoperative analgesic effects,the ability to ambulate and side effects were monitored.Results VAS scores gradually increased in the 4 groups after surgery and were higher between the morning of the 1st day and the evening of the next day than at 4 hours after surgery in all the 4 groups.There were no significant differences in VAS scores between rest and exercise conditions in any of the 4 groups.Ambulatory VAS scores were lower in Groups MN1 and MN2 than in Groups M and N 6 hours after surgery,while resting VAS scores had no significant differences between the 4 groups.Resting and ambulatory VAS scores were both lower in Groups MN1 and MN2 than in Groups M and N 6 hours after surgery,while they had no significant differences between either Groups MN1 and MN2 or Groups M and N 4-8 hours after surgery.Resting and ambulatory VAS scores were lower in Groups M,MN1 and MN2 than in Group M on the morning of the day after surgery,and more patients in Group N needed early tramadol and PCIA for rescue analgesia.Muscle strength was lower in Groups MN1 and MN2 than in Groups M and N 4 hours and on the morning of the day after surgery.No significant differences between the groups were found in standing ability 6 hours after surgery and in motor activity on the morning of the day after surgery.The incidence of urinary retention was higher in Groups M and MN2 than in Groups MN1 and N,and was higher in Group MN1 than in Group N.The incidence of pruritus was higher in Groups M and MN2 than in Group N.There was no significant difference in Ramsay sedation scores and postoperative nausea and vomiting (PONV) between the groups.Conclusions Epidural morphine combined with lumbosacral plexus nerve block can provide better analgesic effects than a single dose of epidural morphine or lumbosacral plexus nerve block in elderly patients undergoing hip joint replacement.Although the synergy of the combination has certain influence on early muscle strength recovery,it does not affect early postoperative rehabilitation training.With the combined use of parecoxib and lumbosacral plexus nerve block,epidural injection of 1 mg and 2 mg morphine provides similar analgesic effects,but epidural injection of 2 mg morphine results in a higher incidence of urinary retention.Thus,a small dose of epidural morphine combined with lumbosacral plexus nerve block is recommended for postoperative analgesia in elderly patients receiving hip joint replacement.

Objective To investigate the effects of regular insulin (RI)on duodenal smooth muscle in diabetic mice. Methods Diabetes mellitus (DM) model was established by intraperitoneal injection of 150 mg/kg streptozotocin (STZ) in male BALB/c mice. The model mice were divided into DM group and DM treated with RI group with 6 each. Meanwhile, 6 normal mice were served as controls. The mice in treatment group were intraperitoneally injected with 40 U/kg of RI daily.Whereas the mice in DM and control groups were intraperitoneally injected with phosphate buffer solution (pH = 7. 40). After 6 weeks, the small intestinal transit rate of mice was determined by lavage of Indian ink. Interstitial cells of cajal (ICC) in duodenal myenteric plexus were counted using immunohistochemical staining. Slow waves of duodenal smooth muscle cells were recorded with intracellular recordings. Data were analysed by SPSS 17.0 software, and comparisons among three groups were done using LSD test. Results After intervention for 6 months, the clinical presentations,such as more water and food intake and polyuria, were improved in treatment group. The body weight was increased in treatment group [(23.33±3.13) g] compared with DM group [(15.42±1.40) g,P<0.01] ,but dereased compared with control group [(26.78 ± 2.09) g, P<0.05]. The level of blood glucose in DM group was significantly higher than that in control and treatment groups(P<0.01). Small intestine transmission rate was significantly reduced in DM group than that in control and treatment groups (P<0.01), but it was slower in treatment group than that in control group (P< 0. 01 ). Immunohistochemical study showed that the number of c-kit positive cells reduced obviously in DM group than that in control group and treatment group (P<0.05), whereas it was lower in treatment group than that in control group (P < 0.05). The slow wave frequency and amplitude of duodenal smooth muscle cells in DM group were reduced when compared with control and treatment groups (P<0.01) and both were lower in treatment group than that in control group (P<0. 01 ). Conclusion The findings indicate that DM mice have gastrointestinal dysmotility and exogenous insulin may improve small intestinal dysmotility in DM mice.
