ABSTRACT
Objective To investigate the clinical effect of adopting B-type ultrasound guided peripherally inserted central catheter (PICC) in the patients with lung cancer.Methods Two hundreds and ninety-five cases of lung cancer undergoing PICC in our hospital from January 2011 to May 2016 were selected as the research subjects and divided into the observation group (151 cases) and control group (144 cases) according to the PICC methods.PICC in the observation group adopted the B-type guided modified Seldinger technique,while the control group adopted the conventional method.The venous thrombus occurrence situation in the two groups was comparatively analyzed.Results (1) The platelet count (PLT),plasma D dimer (D-D) and thromboxane B2 (TXB2),endothelin (ET),6-keto-prostaglandin F1 alpha (6-keto-PGF1α) before PICC had no signigicant difference between the two groups (P>0.05).PLT,D-D,TXB2 and ET at 12,24 h after PICC in the observation group and control group were gradually increased,while plasma 6-keto-PGF1α was gradually decreased,the intra-group difference among different time points had statistical significant (P<0.05).PLT and plasma D-D,TXB2 and ET in the observation group were significantly lower than those in the control group,while keto-PGF1α was significantly higher than that in the control group,the difference between the two groups was statistically significant(P<0.05).(2)The incidence rate of venous thrombosis in the observation group was significantly lower than that in the control group,the difference was statistically significant between the two groups (P<0.05).Conclusion Adopting B-type ultrasound guided modified Seldinger technique for PICC in the patients with lung cancer has much lower incidence rate of venous thrombosis.
ABSTRACT
To evaluate the effectiveness of applying visual electrophysiological examination, including flash visual evoked potentials ( FVEP ) , flash electroretinogram ( FERG ) , pattrn electroretinogram ( PERG ) , fundus photography, eye B-type ultrasound, optical coherence tomography ( OCT ) , on visual function assessment and retinal disease detection before cataract surgery. METHODS: Visual elctrophysiological examination, fundus photography, eye B-type ultrasound and OCT were applied in 148 cases ( 196 eyes ) . The positive rate was analyzed according to the results of FVEP, FERG ( or PERG ) , fundus photography, eye B - type ultrasound and OCT.RESULTS: ln 148 cases ( 196 eyes ) , vitreous opacities was showed in 165 eyes ( 84. 2%) by eye B - type ultrasound examination, 31 eyes (15. 8%) without access to B-type ultrasound image; success for fundus camera images in 161 eyes (80. 6%), and unable to get image in 35 eyes (19. 4%); the VEP and ERG in 58 eyes (29. 6%) were get valuable, and the VEP and ERG were saw no obvious abnormal in 138 eyes ( 70. 4%); success for OCT image in 167 eyes (85. 2%), without access to OCT image in 29 eyes (14. 8%). CONCLUSlON: Visual elctrophysiological detection, fundus photography, eye B-type ultrasound and OCT can predict the preoperative visual acuity of cataractous patients. A variety of inspection methods complement each other, can further improve detection rate of retinal diseases and other eye disease before cataract surgery.
ABSTRACT
Objective To evaluate the clinical effect and influential factors of intrauterine device (IUD) after insertion under B-type ultrasound guidance. Methods A total of 434 healthy women of childbearing potential, aged for 18 to 40 years were enrolled. After IUD insertion under ultrasound guidance, the uterine profile was observed during the procedure and the patients’ biological characteristic was recorded and gynecologic examiation was performed at month 1, 3, 6, 12, 18 during following up. All data were analyzed with SPSS software. Results There was no accident in operation.In 18 months after IUD insertion, the pregnancy rate with IUD was 1.94%,the expulsion rate was 4.59% and the removal rate was 5.54%. The risk factors of expulsion were the history with cesarean delivery and artificial abortion plus IUD insertion (P
