Objective To investigate the diagnostic value of multidirectional diffusion weighted image (DWI) and apparent diffusion coefficient(ADC) image in acute brainstem infarction.Methods 24 cases of brainstem infarction included 2 cases in super acute stage,22 cases in acute stage.All cases were performed multidirectional DWI,ADC and T1 WI、T2 WI examination including of 2 cases of midbrain,21 cases of pons and 1 case of medulla.All of them were accompanied with infarction of other location.Results Among 24 cases there were 13 cases that their lesions displayed clearly and established by transverse T2WI,transverse、coronary or sagittal DWI、ADC and the diagnostic accuracy was 54.2%.In other 9 cases(37.5%) could not display the signal and extent of the lesions,but they could be confirmed by transverse、coronary or sagittal DWI 、ADC.Moreover there were 2 cases(8.3%) who were indicated accurately the diagnosis by coronary、sagittal DWI 、ADC.Conclusion Multidirectional DWI and ADC could show the location of lesions in the lower brainstem so the multidirectional DWI and ADC scan could be an excellent method for the diagnosis of the brainstem infarction.

Objective To observe the acute pain service for analgesia effect and complications of postopera-tive analgesia and satisfaction after cesarean section.Methods 360 patients undergoing cesarean section and postop-erative continue analgesia were randomly divided into two groups.The control group (group C,n =178)was given with routine postoperative self -control analgesia give guidance.In the observation group (group A,n =182),a group for acute pain was founded,and the patients were explained about PCA self -control analgesia related knowledge before operation,together with the APS analgesia group people,the patients were given with postoperative pain management,observed self -control analgesia efficacy and side effects,and gives the corresponding treatment and guidance.The difference of analgesia incomplete and complication were observed such as nausea and vomiting,calm, itchy skin.Questionnaires that postoperative analgesia satisfaction survey were filled inafter discharged.The satisfac-tion of nurse with the APS were observed.Results Postoperative analgesia complication in group A were significantly lower than that in group C(P <0.01,P <0.05),APS analgesic incomplete in group C was significantly higher than groupA (χ2 =11,P <0.01).The satisfaction of PCA in group A were significantly higher than group C (P <0.01, P <0.05),ward nurses job satisfaction also increased significantly (t =2.63,P <0.05).Conclusion Acute pain service effectively improve analgesic quality and reduce related complications after cesarean section increase patients postoperative analgesia satisfaction,increase the ward nurses job satisfaction.

Objective To explore the effect of acute pain group on postoperative analgesia quality and patient satisfac-tion in postoperative pain management. Methods 200 cases of patient controlled analgesia after surgery, were randomly divided into two groups, 100 cases in the control group, routine analgesia and follow-up; 100 patients in the interven tion group, routine analgesia and acute pain teams give full analgesia patient management,unified;observed two groups of patients with postoperative analgesia, adverse reactions and patient satisfaction. Results The analgesia effect of in-tervention group was significantly higher than the control group (P<0.05); Patient controlled analgesia adverse reaction of intervention group was significantly lower than that of the control group(P<0.05);Intervention group patients satisfac-tion was significantly higher than the control group (P<0.05). Conclusion Acute pain group can improve self-control analgesia,decrease patients postoperative analgesia related adverse reactions, improve postoperative analgesia satisfac-tion.
