ABSTRACT
Shear wave elastography (SWE) is used to quantitatively analyze the hardness of the tissue by Young's modulus.The hardness of the tissue is visualized in the form of color coding to distinguish the benign and malignant tissue detected.SWE has higher sensitivity,accuracy and specificity compared with traditional color doppler,which is more objective than elastography,safer,cheaper and simpler than MRI.SWE has a good application prospect in the diagnosis,clinical staging and curative effect monitoring of cervical cancer.
ABSTRACT
Objective: To explore the factors affecting energy efficiency factor (EEF) in high intensity focused ultrasound for adenomyosis. Methods: Data of 130 patients with adenomyosis treated with high intensity focused ultrasound were retrospectively analyzed. The factors affecting EEF in high intensity focused ultrasound were identified with difference and correlation analyses. And a multiple linear regression equation was obtained by multivariate analysis. Results: The course of disease (X1), abdominal wall scar (X2), gonadotropin releasing hormone agonist (GnRH-a) pretreatment (X3), blood flow grade (X4), abdominal wall thickness (X5) and target-skin distance (X6) were the influencing factors of EEF in high intensity focused ultrasound with the multiple linear regression equation as Y=-17.742+1.153X1+14.927X2-13.846X3+4.713X4+1.422X5+0.227X6. Conclusion: High intensity focused ultrasound treatment presents lower EEF and higher ablation efficiency in patients with adenomyosis who have short course of disease, no abdominal wall scar, GnRH-a pretreatment, little blood flow in the lesion, thin abdominal wall and short target-skin distance.
ABSTRACT
Objective To study the effects of the multi-model analgesia for the old patients who received total hip replacement surgery.Methods Thiry-four patients who would received total hip replacement surgery were randomly divided into 2 group:Group E was the epidural analgesia group and Group M was the multi-model analgesia group.15min before the end of surgery,the load doses were given to the patients in both groups and the electric pumps for postoperative analgesia were connected.The multi-model analgesia was used for Group M:30min before the end of surgery,ropivacaine 7.5mg and morphine 1mg were given via epidural catheter,and at the end of surgery the catheter was pulled out.Intravenous analgesic pumb were used for Group M.Record the following data at different time point (T1 to T5):(1)the pain scores.(2)the scores of sedation and HR,MAP,RR and SpO2.(3)the numbers of the patients who suffered from adverse effects,such as nausea and vomiting and the numbers of patients who needed the rescue medicine were recorded in 48h after surgery.Results Compared to Group E,the scores of pain when the patients turned over in Group M,were lower significantly at T2.At T1 and T2 time point,the sedation scores of Group M were higher than those of Group E significantly.There was significant difference in the SpO2 change between groups at T1.Conclusion The multi-model analgesia of using long-acting local anesthetics and opioids for epidural analgesia once,then using sufentanil and tramadal for intravenous analgesia continuously,was safe and sufficient for the old patients.
