RESUMEN
Objective To compare the safety and efficacy of the caudal block and Total Intravenous Anesthesia (TIVA) for transrectal ultrasound (TRUS) guided prostate biopsy.Methods 60 elderly patients with transrectal ultrasound guided transperineal prostate biopsy were randomized into Group A and Group B.Patients in Group A received ultrasound guided caudal block (0.33％ ropivacaine 15 ml) and patients in Group B received TIVA.In operation room (T1),immediately before operation (T2) and at the end of operation (T3),mean artery pressure (MAP),heart rate (HR),breathing rate (BR) and pulse oxygen saturation (SpO2) were recorded.The patients in two groups were rated the level of mini-mental state examination (MMES) at 2 h,8 h and 24 h after operation.Complications during the whole study period were also evaluated.Results The values of MAP,HR and BR of T1 in group B were significantly lower than those at T2 (P＜0.05),and were lower than those in the group A (P ＜0.05).The MMSE value in group A [2 h (25.66 ± 1.71) and 8 h (26.13 ± 1.52)] was significantly higher than that in group B [2 h (27.96 ± 1.71) and 8 h (29.01 ± 0.77)] at after operation (P ＜ 0.05).The rate of usage of ephedrine (13％) and assisted ventilation (20％) in group B was higher.No significant differences were detected in side effects between the two groups.Conclusions Caudal block provides better anesthesia than TIVA for TRUS guided prostate biopsy without an increase of side effects,and it may be safely used during ambulatory surgery.
RESUMEN
ObjectiveTo explore puncture point and angle of skin for unipedicular vertebroplasty by imaging measurement and combining clinical practice in order to pr vide reference for clinical work.MethodsCT images of thoracic and lumbar vertebrae of imaged with multislice helical CT were random chosen.From high to low position vertebrae of easy fracture T6 to -L5,its angle between vertebraI pedfcle stalk line and 1/3 of vertebraI body stalk line fore and median of point of intersection was measured.The angle of sternocostal joints route was also measured.At the same time the distance between site of skin puncture and spinous process was measured.ResultsThe angle between the thoracic vertebraI pedicle and sagittal section was (28.2 ± 3.8) °,the lateral distance of the spinous process was ( 31.6 ± 5.4) mm.The angle of thoracic vertebraI pedicle lateral route was (35 ± 3.4) °,the distance was ( 55.2 ± 5.3 ) mm.In the lumbar vertebrae pedicle route,the angle of L1 -L4 was (29.3 ± 5.6 ) °,the distance was (38.4 ± 4.5 )mm.Ls was (39.2 ± 3.3) °,the distance was ( 71.6 ± 6.2) mm.Combining clinical practice,the lateral distance of the spinous process in thoracic vertebraIpedicle route,the best puncture point was 30 mm,in thoracic vertebraI pedicle lateral route it was 40 mm,in L1-L4 it was 45 mm,in L5 it was 60 mm.ConclusionsThe unipedicular vertebroplasty can be performed rapidly,accurately and safely,and it reduces complications,cost and time.
