Radiological feeding tube insertion is a safe and effective procedure. Success rates are higher, and complication rates lower than PEG or surgical gastrostomy tube placement and innovative techniques for gastric and jejunal access mean that there are very few cases in which RIG is not possible. The principal weakness of radiologically inserted gastrostomies is the limitiation on tube size which leads to a higher rate of tube blockage. Per-oral image-guided gastrostomies have to an extent addressed this but have not been popularised. Currently many centres still consider endoscopic gastrostomies as the first line unless patients are too unwell to undergo this procedure or previous attempts have failed, in which case radioloically inserted gastrostomies are the technique of choice.
Background and Purpose— In ischemic stroke, body temperature is associated with functional outcome. However, the relationship between temperature and outcome may differ in the intraischemic and postischemic phases of stroke. We aimed to determine whether body temperature before or after endovascular thrombectomy (EVT) for large vessel occlusion stroke is associated with clinical outcomes. Methods— Consecutive EVT patients were identified from a prospective registry. Temperature measurements within 24 hours of admission were stratified into pre-EVT (preprocedural and intraprocedural) and post-EVT measurements, which served as surrogates for the intraischemic and postischemic phases of large vessel occlusion stroke, respectively. The primary outcome was functional independence, defined as a modified Rankin Scale score of 0, 1, or 2 at 3 months. Secondary outcomes included the ordinal shift of modified Rankin Scale scores at 3 months, symptomatic intracerebral hemorrhage, and mortality at 3 months. Results— Four hundred thirty-two participants were included (59% men, mean±SD age 65.6±15.7 years). Multivariable logistic regression demonstrated that higher median pre-EVT temperature (per 1°C increase) was an independent predictor of reduced functional independence (odds ratio [OR], 0.66 [95% CI, 0.46–0.94]; P =0.02), poorer modified Rankin Scale scores (common OR, 1.42 [95% CI, 1.08–1.85]; P =0.01), and increased mortality (OR, 1.65 [95% CI, 1.02–2.69]; P =0.04). Peak post-EVT temperature (per 1°C increase) was a significant predictor of elevated modified Rankin Scale scores (common OR, 1.39 [95% CI, 1.03–1.90]; P =0.03) and higher mortality (OR, 1.66 [95% CI, 1.04–2.67]; P =0.03). Conclusions— In patients with large vessel occlusion stroke treated with EVT, higher body temperatures during both the intraischemic and postischemic phases were associated with poorer clinical outcomes. Future research investigating the maintenance of normothermia or therapeutic hypothermia in patients needing to be transferred from primary to EVT-capable stroke centers could be considered.
BackgroundIn ischemic stroke, increased glycated hemoglobin (HbA1c) and glucose levels are associated with worse outcome following thrombolysis, and possibly, endovascular thrombectomy.ObjectiveTo evaluate the association between admission HbA1c and glucose levels and outcome following endovascular thrombectomy.MethodsConsecutive patients treated with endovascular thrombectomy with admission HbA1c and glucose levels were included. The primary outcome was functional independence, defined as a modified Rankin Scale score of 0–2 at 3 months. Secondary outcomes included successful reperfusion (modified Thrombolysis in Cerebral Infarction 2b-3), early neurological improvement (reduction in National Institutes of Health Stroke Scale (NIHSS) score ≥8 points, or NIHSS score of 0–1 at 24 hours), symptomatic intracerebral hemorrhage (sICH), and mortality at 3 months.Results223 patients (136 (61%) men; mean±SD age 64.5±14.6) were included. The median (IQR) HbA1c and glucose were 39 (36-45) mmol/mol and 6.9 (5.8–8.4) mmol/L, respectively. Multiple logistic regression analysis demonstrated that increasing HbA1c levels (per 10 mmol/mol) were associated with reduced functional independence (OR=0.76; 95% CI 0.60–0.96; p=0.02), increased sICH (OR=1.33; 95% CI 1.03 to 1.71; p=0.03), and increased mortality (OR=1.26; 95% CI 1.01 to 1.57; p=0.04). There were no significant associations between glucose levels and outcome measures (all p>0.05).ConclusionsHbA1c levels are an independent predictor of worse outcome following endovascular thrombectomy. The addition of HbA1c to decision-support tools for endovascular thrombectomy should be evaluated in future studies.
Background: The choice of anesthetic technique for ischemic stroke patients undergoing endovascular thrombectomy is controversial. Intravenous propofol and volatile inhalational general anesthetic agents have differing effects on cerebral hemodynamics, which may affect ischemic brain tissue and clinical outcome. We compared outcomes in patients undergoing endovascular thrombectomy with general anesthesia who were treated with propofol or volatile agents. Methods: Consecutive endovascular thrombectomy patients treated using general anesthesia were identified from our prospective database. Baseline patient characteristics, anesthetic agent, and clinical outcomes were recorded. Functional independence at 3 months was defined as a modified Rankin Scale of 0 to 2. Results: There were 313 patients (182 [58.1%] men; mean±SD age, 64.7±15.9 y; 257 [82%] anterior circulation), of whom 254 (81%) received volatile inhalational (desflurane or sevoflurane), and 59 (19%) received intravenous propofol general anesthesia. Patients with propofol anesthesia had more ischemic heart disease, higher baseline National Institutes of Health Stroke Scale scores, more basilar artery occlusion, and were less likely to be treated with intravenous thrombolysis. Multivariable logistic regression analysis showed that propofol anesthesia was associated with improved functional independence at 3 months (odds ratio=2.65; 95% confidence interval, 1.14-6.22; P=0.03) and a nonsignificant trend toward reduced 3-month mortality (odds ratio=0.37; 95% CI, 0.12-1.10; P=0.07). Conclusion: In stroke patients undergoing endovascular thrombectomy treated using general anesthesia, there may be a differential effect between intravenous propofol and volatile inhalational agents. These results should be considered hypothesis-generating and be tested in future randomized controlled trials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
