| Objective: To observe the effect and security of a comfortable urinary catheter on catheter-related bladder discomfort in patients after orthopedics surgery.Methods : ninty elective orthopedics adult patients,male,age from 18 to 60,ASA physical status Ⅰand Ⅱ, undergoing catheterization,were randomly divided into three groups of 30 each. Comfortable urinary catheter(L)group received 16 F comfortable urinary catheter after induction of anesthesia; D group(Dexmedetomidine) and C group(control)received 16 F Foley’s catheter after induction of anesthesia, and the balloon was inflated with 10 ml normal saline. L group received 2% lidocaine 5ml via the injection port of balloon of comfortable urinary catheter,D group received dexmedetomidine 0.5ug/kg(diluted in 20 ml NS), C group received NS 20 ml.D group and C group were given concecutive intravenous infusion in 10 min with micromedicine infusion-pump before extubation. All medications were administered 10 min before extubation.After tracheal extubation,the incidence and severity(mild,moderate,and severe)of CRBD were assessed at 0, 0.5, 1,2,and 6 h.The Ramsay and VAS of all the patients were recorded inthe 3groups.Results: 1.At every time point,L group and D group had a significantly lower incidence and severity than C group(P<0.05).The incidence and severity of CRBD in L group was significantly lower than D group. 2.VAS pain score in L group and D group were more lower than C group in each time. Whereas there were no difference between L group and D group(P>0.05);3.Compared with C group and L group,Ramsay sedation score in D group was much higher at 0,0.5,1 and 2h(P<0.05). While there were no difference between L group and C group(P>0.05).Conclusions: Comfortable urinary catheter could significantly decreases the incidence and severity of CRBD,Whereas the incidence and severity in Comfortable urinary catheter group was significantly lower than in Dexmedetomidine group. |
