Suppression of the vestibular short-latency evoked potential by electrical stimulation of the central vestibular system.

Suppression of the vestibular short-latency evoked potential by electrical stimulation of the central vestibular system. Hear Res. 2018 Feb 02;361:23-35 Authors: Pastras CJ, Curthoys IS, Sokolic L, Brown DJ Abstract In an attempt to view the effects of the efferent vestibular system (EVS) on peripheral dynamic vestibular function, we have monitored the Vestibular short-latency Evoked Potential (VsEP) evoked by pulses of bone conducted vibration during electrical stimulation of the EVS neurons near the floor of the fourth ventricle in the brainstem of anesthetized guinea pigs. Given the reported effects of EVS on primary afferent activity, we hypothesized that EVS stimulation would cause a slight reduction in the VsEP amplitude. Our results show a substantial (>50%) suppression of the VsEP, occurring immediately after a single EVS current pulse. The effect could not be blocked by cholinergic drugs which have been shown to block efferent-mediated vestibular effects. Shocks produced a short-latency P1-N1 response immediately after the electrical artifact which correlated closely to the VsEP suppression. Ultimately, we have identified that this suppression results from antidromic blockade of the afferent response (the VsEP). It would appear that this effect is unavoidable for EVS stimulation, as we found no other effects. PMID: 29433062 [PubMed - as supplied by publisher]

Conclusion: The decision-to-delivery interval was ≤ 15 min in most women, suggesting that optimised organisation ensures short decision-to-delivery interval independently of the anaesthetic technique performed. As general anaesthesia was associated with worse neonatal outcomes, our results support the early insertion of an epidural catheter whenever there is any potential concern that an emergency caesarean section may be required.

This study aims to evaluate the efficacy and safety of esophageal ESD under GA. Methods: A total of 227 lesions from 198 consecutive patients with superficial esophageal neoplasms treated by ESD at 3 Japanese institutions between April 2011 and September 2017 were included in this retrospective study. For ESD, GA and deep sedation (DS) were used in 102 (51.5%, GA group) and 96 patients (48.5%, DS group), respectively. Results: There were no statistically significant differences in age, sex, or comorbidities between the groups. In the GA group, the tumor size was larger (21 [3-77] mm vs. 14 [3-63] mm, p

Might be a dumb question, but any of you do this? I figure not having your hospital withhold your tax gives a significant temporary boost to investable income. Even if you put it in a high saving account and get 2% interest.. can still get like 1000$ extra a year? Then just pay the taxes due during tax season. Am i missing something?
