ABSTRACT

Objective:To investigate the impacts of conscious sedation and general anesthesia on the functional outcome after endovascular therapy (EVT) in elderly patients with acute ischemic stroke with large vessel occlusion (AIS-LVO).Methods:The clinical and imaging data of elderly patients with AIS-LVO (≥80 years) underwent EVT at the Affiliated Hospital of Nantong University from January 2020 to January 2023 were collected retrospectively. They were divided into conscious sedation group and general anesthesia group according to anesthesia modality, and divided into good outcome group (0-2 points) and poor outcome group (>2 points) based on the modified Rankin Scale score at 90 d after onset. The multivariate logistic regression analysis was used to investigate the impact of anesthesia modality on functional outcome after EVT. Results:A total of 77 elderly patients with AIS-LVO were enrolled, including 35 males (45.5%) and 42 females (54.5%); median age of 82.0 years (interquartile range, 80.0 to 84.0 years); the median baseline NIHSS score was 16.0 (interquartile range, 10.0-20.0). Conscious sedation was used in 21 cases (27.3%) and general anesthesia was used in 56 cases (72.7%); 17 (22.1%) had good outcome, while 60 (77.9%) had poor outcome. Compared with the general anesthesia group, the conscious sedation group had a longer procedure time (110.0 min vs. 89.0 min; P=0.049), but a higher rate of good outcome at 90 d (38.1% vs. 16.1%; P=0.038), a lower incidence of stroke-associated pneumonia (33.3% vs. 58.9%; P=0.045), and a lower proportion of patients who underwent tracheostomy after procedure (4.8% vs. 25.0%; P=0.046). Compared with the poor outcome group, the good outcome group had shorter procedure time (75 min vs. 99 min; P=0.033), lower incidence of stroke-associated pneumonia (29.4% vs. 58.3%; P=0.035), lower tracheotomy rate (0% vs. 25%; P=0.022), and a lower proportion of patients who received conscious sedation (47.1% vs. 21.7%; P=0.038). Multivariate logistic regression analysis showed that conscious sedation was an independent predictor of good outcome (odds ratio 0.090, 95% confidence interval 0.010-0.771; P=0.028). Conclusion:Conscious sedation may be more appropriate for elderly patients with anterior circulation AIS-LVO undergoing endovascular treatment.

ABSTRACT

Objective The effect of left atrial (LA) dimension on the occurrence of atrial fibrillation (AF) has been examined in some small studies.Less is known about the relationship of LA dimension,hemodynamic with AF during echocardiographic evaluation,especially,the flow dynamics in LA poorly described.The objective of this study was to investigate the relationship between LA dimension and the occurrence of AE Methods Two hundred and forty-five consecutive patients with heart disease scheduled to undergo open heart surgery were prospectively enrolled in the study.Patients were divided into 2 groups according to atrial fibrillation:AF group (n=148,99 men and 49 women,with a mean age 59.3+8.4 years),and no-AF group (n= 97,60 men and 37 womem).Echocardiography was performed before surgery.All measurements were performed following the American Society of Echocardiography recommendations.Results There were more patients with congestive heart failure in AF group than in no-AF group (45.9% vs 39.1%,P <0.05).The mean LA volume was 49.2±12.2 ml/m2 in AF group and 33.1±10.8 ml/m2 in no-AF group.There were also significant differences between two groups in left atrial end systolic dimension (LAESD) (50±13mm vs 27±14mm),left atrial end diastolic dimension (LAEDD) (79±17mm vs 53±13mm),PA pressure ( 41.3+11.6 mmHg vs 37.5±10.4 mmHg),and ratio of mitral E velocity and septal mitral annulus motion velocity (E/E') .The percentage of abnormal diastolic function grades (DGF) was also higher in AF than in no-AF group (89.9% versus 59.8% );.Conclusion Atrial fibrillation is associated more frequently with an increased LA dimension and more severe atrial hemodynamics disorder.(J Geriatr Cardiol 2008;5:11-4)

ABSTRACT

Objective To study the 2-4 years intermediate-term clinical effects of bone-patellar tendon-bone (B-PT-B) autograft plus interface screw method and quadruple semitendinosus tendon autograft plus endobutton plate fixation method in anterior cruciate ligament (ACL) reconstruction after ACL injury and to estimate the correlation of various implants and fixation techniques with clinical effect. Methods A retrospective analysis was done on 104 cases with ACL injury as well as detailed clinical data from October 1998 to October 2000. ACL reconstruction with bone-patellar tendon-bone autograft (PT group) and kurosaka interface screw fixation were performed in 55 cases and quadruple semitendinosus tendon autograft and endobutton plate fixation (ST group) in 49 cases. The average follow up was 38.5 months in the PT group and 35.7 months in the ST group. We compared the intermediate myodynamic recovery, ROM, lachman test, pivot shift test, IKDC score, lysholm score, Werner score and X-ray view of tunnul enlargement between two groups. Results In the PT group, the circumference of thigh was (1.097?0.079) cm, shorter than that of normal side, and (0.896?0.126) cm in the ST group. The cases accounting for 82% (45/55) in the PT group and 88% (43/49) in the ST group had extension limitation less than 3?. Knee flexion limitation of 0?-5? accounted for 87% (48/55) in the PT group and 86% (42/49) in the ST group. Bilateral comparison of Lachman test less than 5 mm accounted for 93% (51/55) in the PT group and 96% (47/49) in the ST group. Negative rate of pivot shift test was 89% (47/55) in the PT group and 92% (45/49) in ST group. Bilateral comparison of AP knee laxity with 20Ib KT-1000 in laxity with less than 3 mm accounted for 53% (29/55) in the PT group and 57% (28/49) in the ST group. Lyoholm score in the PT group was increased from preoperative 69.2?6.4 to postoperative 86.7?4.3 and that in the ST group from 68.3?7.5 to 88.4?8.6. Knee motion standard of IKDC score in the PT group was 78%(43/55), which was found normal or nearly normal, and 82%(40/49) in the ST group. Patellar femoral pain Werner score was 43.0 ?6.1 in the PT group while 45.0?6.3 in the ST group. The X-ray showed that tunnel enlargement phenomena was 53% (29/55) in the PT group while 43% (21/49) in the ST group. Conclusions From 2-4 years intermediate-term follow up, there is no significant difference in ACL reconstruction using patellar tendon autograft plus interface screw method and quadruple semitendinosus tendon plus endobutton plate fixation method. Bone grafting in the donor site can reduce the incidence of anterior knee pain. Twisting technique is beneficial to overcome of the postoperative laxity caused by viscular elasticity of quadruple semitendinosus.
