Although Ernst von Bergmann (1837-1907) is considered the father of neurosurgery in Germany, Fedor Krause (1857-1937) should be considered as its main founder. He was principally a general surgeon but he had a special interest in neurosurgery, a field in which he introduced many new techniques. He also fabricated innovative surgical methods for the treatment of patients with epilepsy.
<p>The aim was to study Adriaan van den Spiegel’s ideas on ocular anatomy. He is better known by his Latinized name as Adrianus Spigelius (1578 – 1625). He was a Flemish physician and anatomist who lived and worked in Padua, where in 1605 he was elected to be Professor of Anatomy and Surgery. Chapter IX of book ten of Spigelius’ work on human anatomy, entitled <em>De humani corporis fabrica libri X tabulis aere icisis exornati </em>(1627) was devoted to an anatomical description of the eye. Corresponding to contemporary ideas of the production of knowledge Spigelius endeavoured to enhance Andreas Vesalius’ (1514–1564) anatomy, he did not repeat his predecessor’s theories of ocular anatomy. He conceptualised that the eye has six muscles, five tunics and three humors, while he gave a brief description of ocular physiology combining anatomy and the functional role of the anatomic ocular parts.</p><p><strong>Conclusion. </strong>He managed to correct Vesalius’ errors and to present ocular anatomy with original notes, which so far, have been ignored and are highlighted now.</p>
Carl Ferdinand von Arlt, Ritter von Bergschmidt (1812-1887) was a pioneer in ophthalmology. The purpose of our paper is to highlight his scientific work. He did not only introduce new surgical techniques and invent new instruments in ocular surgery, but also influenced the development of ophthalmology in the 19 th century. He was an excellent and reputable professor of ophthalmology, and his students became very respected figures in ophthalmology.
Aim of the study is the evaluation of preemptive multimodal analgesia vs established technique of single epidural, in Ivor Lewis esophagectomy, perioperatively. Background & Methods In a randomized prospective trial, 25 patients were randomly assigned to two groups (A=12: preemptive multimodal analgesia, and B=13: epidural analgesia) after informed consent. Patients with coagulative disorders, and renal or hepatic impairment were excluded from study. In all patients a thoracic epidural (T5 – T7) was placed before anesthesia induction. Anesthetic protocol was the same, according body weight, in both groups, apart from analgesic drugs. Group A patients received morphine 1.5-3mg and ropivacaine 0.25% 10-12 ml epidurally (ed), and paracetamol 1gr, parecoxib 40mg, clonidine 150mcg, dexamethasone 8mg, lidocaine 1mg/kg, and magnesium sulfate 25% 10 ml iv, at least 20 min before surgical incision, while in group B same doses of ed morphine and ropivacaine were administered post-incision and iv paracetamol and parecoxib were administered 1hr before end of surgery. Surgical incision infiltration in both wounds with ropivacaine 0.375% 20ml was performed jn both groups’ patients. Intraoperative opioid doses were titrated accordingly. Analgesic needs intra- and postoperatively, as well as vital signs stability and side effects such as postoperative nausea or vomiting (PONV), dizziness, sleepiness, and respiratory suppression were recorded. Results Group A patients received significantly lower opioid doses intraoperatively (p<0.001), 2 (17%) of them did not need extra opioids at all, and in 8 (67%), operation was completed with only one low dose of fentanyl (2-3mcg/kg) before abdominal surgical incision. Group A patients had stable heart rate (HR) and blood pressure (BP) during whole operation, while 11 (84.6%) from group B (p<0.001) demonstrated HR and BP raising in certain surgical times. All both groups’ patients were transferred to ICU awake. 5 (38.46%) group B patients (p>0.005) required rescue amalgesic post-awakening. None of both groups’patients demonstrated any drugs’ side effects. Conclusion Preemptive multimodal analgesia seems to be more efficient, reducing needs for opioids intraoperatively, rescue analgesics postoperatively and providing better hemodynamic stability, than single epidural. Further studies are needed to support this conclusion.
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.
