Intraoperative tramadol reduces shivering but not pain after remifentanil–isoflurane general anaesthesia. A placebo-controlled, double-blind trial
2008
Background and objective Postoperative shivering and pain are frequent problems in patients recovering from anaesthesia with particularly high incidences being observed after remifentanil–isoflurane-based general anaesthesia. The opioid tramadol is generally effective in preventing shivering and treating pain, but its effects are not characterized after remifentanil-based general anaesthesia. This randomized, placebo-controlled, double-blind study evaluated the effects of intraoperative intravenous tramadol on postoperative shivering and pain after remifentanil-based general anaesthesia. Methods After Ethics Committee approval, 60 patients scheduled for lumbar disc surgery were included. Su…
A comparison of the Enk Fiberoptic Atomizer Set(™) with boluses of topical anaesthesia for awake fibreoptic intubation.
2016
We compared the Enk Fiberoptic Atomizer Set(™) with boluses of topical anaesthesia administered via the working channel during awake fibreoptic tracheal intubation in 96 patients undergoing elective surgery. Patients who received topical anaesthesia via the atomiser, compared with boluses via the fibreoptic scope, reported a better median (IQR [range]) level of comfort: 1 (1-3 [1-10]) vs. 4 (2-6 [1-10]), p < 0.0001; experienced a reduced total number of coughs: 6 (3-10 [0-34]) vs. 11 (6-13 [0-25]), p = 0.0055; and fewer distinct coughing episodes: 7% vs. 27% respectively, p = 0.0133. The atomiser technique was quicker: 5 (3-6 [2-12]) min vs. 6 (5-7 [2-15]) min, p = 0.0009; and required less…
Intraoperative clonidine modulates sympathetic tone in the early postoperative period after remifentanil. A double blind, placebo-controlled study
1999
Abstract Aim of the study : Severe pain following major surgery can impair the control of the cardiovascular system (CVS) by causing sympathetic stimulation, possibly leading to myocardial ischaemia. In this study we examine the influence of intraoperative intravenous (i.v.) clonidine infusion on postoperative analgesia and blood concentrations of noradrenaline and adrenaline after major gynaecological surgery. Methods : All patients underwent an abdominal hysterectomy under balanced general anaesthesia using the new opioid remifentanil. The patients were randomised to receive either 5 μg kg −1 of i.v. clonidine intraoperatively ( n =20), or placebo ( n =20). Over a period of 240 minutes po…
Ventilating the newborn and child
2010
Summary The mechanical ventilation of neonates and children in operating theatres has always posed a challenge for anaesthesiologists. Firstly, the extreme physiological features of neonatal lungs make them very difficult to ventilate with an anaesthesia ventilator. Gattinoni's "baby lung" concept to describe ARDS lungs in adults comes from the physiological features of neonatal lungs (low dynamic compliance, low pulmonary time constant, low FRC, high closing volume, proneness to atelectasis, high inspiratory airway resistance). Secondly, the performance and technology (peak flow, insufflation power, trigger sensitivity, ventilation modes, etc.) of anaesthesia ventilators is still less adva…
Regional analgesia in postsurgical critically ill patients
2017
Regional analgesia intrinsically, based on its physiological effects, is routinely used for the perioperative treatment of pain associated with surgical procedures. However, in other areas such as the non-surgical treatment of acute pain for patients in a critical condition, it has not been subjected to specific prospective studies. If we confine ourselves to the physiological effects of the nerve block, in a situation of stress, the indications for regional anaesthesia in this group of patients extend to the management of a wide variety of medical as well as postsurgical conditions, of trauma patients and of other painful procedures performed in the patient's bed. The critical patient cert…
Local vs general anaesthesia in the development of neurosensory disturbances after mandibular third molars extraction: A retrospective study of 534 c…
2016
Background The choice of the anaesthetic modality is one of the primary steps during planning of third molar surgery. The aim of the present study was to compare the risk of developing neurological injures of the inferior alveolar nerve (IAN) and lingual nerve (LN) in patients treated for wisdom teeth removal under general anaesthesia (GA) with a group treated under local anaesthesia (LA). Material and Methods This is an observational retrospective, unicentric study; between September 2013 and September 2014, 534 patients underwent third molar surgery, 194 (36,3%) under GA and 340 (63,7%) under LA by the same oral surgeon. Differences in the incidence of IAN and LN injures between groups ha…
General anaesthetics and the developing brain: an overview
2014
Various experimental studies in animals have shown that general anaesthetics are potentially toxic to the developing brain. By inducing apoptosis or interfering with neurogenesis, anaesthetic exposure during a critical period of neuronal development can have significant impact on neurocognitive function later in life. It remains controversial whether these experimental results can be transferred to human beings and this is under intensive scientific evaluation. To gain more insight into possible neurotoxic effects on the human brain of infants and small children, a number of retrospective studies have been performed. At present, there is no clear evidence that exposure to anaesthesia up to …
The perioperative management of small animals with previously implanted pacemakers undergoing anaesthesia.
2020
Abstract Objective There is little information in the veterinary literature about the perioperative management of small animal patients with previously implanted pacemakers undergoing elective or emergency non-cardiac procedures. The purpose of this article is to review the current literature with regard to human patients, with previously implanted pacemakers, undergoing general anaesthesia. Using this and the current information on pacemakers and anaesthesia in dogs and cats, we provide recommendations for small animal patients in this situation. Databases used Google Scholar, PubMed and CAB Abstracts using and interlinking and narrowing the search terms: “dog”, “cat”, “small animals”, “an…
Comparison of minimally invasive parathyroidectomy under local anaesthesia and minimally invasive video-assisted parathyroidectomy for primary hyperp…
2016
Background: Primary hyperparathyroidism (PHPT) origins from a solitary adenoma in 70-95% of cases. Moreover, the advances in methods for localizing an abnormal parathyroid gland made minimally invasive techniques more prominent. This study presents a micro-cost analysis of two parathyroidectomy techniques. Patients and methods: 72 consecutive patients who underwent minimally invasive parathyroidectomy, video-assisted (MIVAP, group A, 52 patients) or "open" under local anaesthesia (OMIP, group B, 20 patients) for PHPT were reviewed. Operating room, consumable, anaesthesia, maintenance costs, equipment depreciation and surgeons/anaesthesiologists fees were evaluated. The patient's satisfactio…
Publications on paediatric anaesthesia: a quantitative analysis of publication activity and international recognition.
2000
A comprehensive compilation of the current international literature on paediatric anaesthesia is lacking. The aim of this study was to identify all articles on clinical practice in paediatric anaesthesia, to name the respective journals, and to assess the publication activity and international recognition of selected countries for a 6-yr period (1993–1998). The search comprised an article-to-article evaluation (‘hand search') of 12 peer-reviewed anaesthesia journals, as well as an Internet-based (‘SilverPlatter') MedlineTM-search (3.900 medical journals, US National Library of Medicine), both limited to original articles, case reports, reviews and editorials. Selected physical characteristi…
