Anaesthesia

Clinical Anaesthesia is used to induce a temporary medical state of controlled unconsciousness, inducing a loss of sensation or awareness. There are three main types of Anaesthesia:

  • Local and Regional
  • General
  • Sedation

Anaesthesia is primarily used during surgical procedures to block pain. While unconscious, blood flow and heart rate is monitored.

Research and development in the use of Anaesthesia has helped anesthesiologists in the progression of patient safety before and after surgery and medical procedures. The developments and research of Anaesthesia through the years has massively influences medicine and surgery today.

Case studies and clinical trials help aid researchers in the development of aftercare during postoperative recovery. Research is a vital part in the field of Anaesthesia, it allows anesthesiologists to improve the delivery of patient safety while unconscious.

Hyperbaric versus isobaric bupivacaine for spinal anaesthesia for caesarean section. Bupivacaine is an amide local anaesthetic used in hyperbaric and isobaric forms. These are administered intrathecally into the spine to provide regional anaesthesia for caesarean section. Several trials have compared hyperbaric and isobaric bupivacaine but none have conclusively shown the benefit of either. This review was first published in 2013 and updated in 2016.Our objectives were to:1. Determine (...) the effectiveness of hyperbaric bupivacaine compared to isobaric bupivacaine for spinal anaesthesia in women undergoing caesarean section;2.

Intravenous versus inhalational techniques for rapid emergence from anaesthesia in patients undergoing brain tumour surgery. Brain tumour surgery usually is carried out with the patient under general anaesthesia. Over past years, both intravenous and inhalational anaesthetic agents have been used, but the superiority of one agent over the other is a topic of ongoing debate. Early and rapid emergence from anaesthesia is desirable for most neurosurgical patients. With the availability of newer (...) intravenous and inhalational anaesthetic agents, all of which have inherent advantages and disadvantages, we remain uncertain as to which technique may result in more rapid early recovery from anaesthesia.To assess the effects of intravenous versus inhalational techniques for rapid emergence from anaesthesia in patients undergoing brain tumour surgery.We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 6) in The Cochrane Library, MEDLINE via Ovid SP (1966 to June 2014

[Single Subcutaneous Palmar Injection vs. 2 Dorsal Injections for Finger Anaesthesia in Hand Surgery - Randomised Prospective Comparison of Application Pain and Efficacy]. This randomised prospective study compared pain during application and efficacy of the palmar subcutaneous single injection block (PSSIB) and the traditional dorsal 2 injection block (DTIB).During a 2 year period, a total of 190 patients with an average age of 43 years (18-82) and an isolated finger injury were included (...) as complete pain-free, almost pain-free and inadequate anesthesia (second injection was necessary). Statistical analysis was performed using the chi-quadrat and the t test; the level of significance was set at p<0.05.There was no significant difference in terms of analgesic efficacy (p=0,096), while the PSSIB required fewer second injections. Application pain was rated as being significantly (p=0.002) less painful for PSSIB (3.2) than for DTIB (4,0).This study shows that PSSIB gives reliable analgesia

Nitrous oxide-based versus nitrous oxide-free general anaesthesia and accidental awareness during general anaesthesia in surgical patients. Accidental awareness during general anaesthesia (AAGA) is when a patient unintentionally becomes conscious during a procedure performed with general anaesthesia and subsequently has explicit recall of this event. Incidence estimates for AAGA vary, with the most common estimate being one to two cases per 1000 general anaesthetics. Evidence linking nitrous (...) general anaesthesia that included nitrous oxide for maintenance at a concentration of at least 30% were compared with participants receiving no nitrous oxide during general anaesthesia. The intervention group must have received nitrous oxide in conjunction with an additional anaesthetic. We excluded studies where the depth of anaesthesia differed between the study arms. For inclusion in the review, studies needed to state in their methods that they planned to assess AAGA. We defined this as when

Management of these patients presents technical challenges and complexities because of underlying psychiatric disorders that are often associated (...) emergency intervention in theater under general anesthesia. After the third attendance in 5 days, it was decided to use Isiris™, a single-use flexible cystoscopy device with a built-in ureteral stent grasper, to remove the FBs and check the integrity of the urethra.

Furthermore, only two members of staff were required to remove all of the urethral FBs.Isiris, although marketed as a stent

178. Effect of regional versus local anaesthesia on outcome after arteriovenous fistula creation: a randomised controlled trial. (Abstract)

Effect of regional versus local anaesthesia on outcome after arteriovenous fistula creation: a randomised controlled trial. Arteriovenous fistulae are the optimum form of vascular access in end-stage renal failure. However, they have a high early failure rate. Regional compared with local anaesthesia results in greater vasodilatation and increases short-term blood flow. This study investigated whether regional compared with local anaesthesia improved medium-term arteriovenous fistula (...) patency.This observer-blinded, randomised controlled trial was done at three university hospitals in Glasgow, UK. Adults undergoing primary radiocephalic or brachiocephalic arteriovenous fistula creation were randomly assigned (1:1; in blocks of eight) using a computer-generated allocation system to receive either local anaesthesia (0·5% L-bupivacaine and 1% lidocaine injected subcutaneously) or regional (brachial plexus block [BPB]) anaesthesia (0·5% L-bupivacaine and 1·5% lidocaine with epinephrine

179. Molecular and Integrative Physiological Effects of Isoflurane Anesthesia: The Paradigm of Cardiovascular Studies in Rodents using Magnetic Resonance Imaging Full Text available with Trip Pro

Molecular and Integrative Physiological Effects of Isoflurane Anesthesia: The Paradigm of Cardiovascular Studies in Rodents using Magnetic Resonance Imaging To-this-date, the exact molecular, cellular, and integrative physiological mechanisms of anesthesia remain largely unknown. Published evidence indicates that anesthetic effects are multifocal and occur in a time-dependent and coordinated manner, mediated via central, local, and peripheral pathways. Their effects can be modulated by a range (...) of variables, and their elicited end-effect on the integrative physiological response is highly variable. This review summarizes the major cellular and molecular sites of anesthetic action with a focus on the paradigm of isoflurane (ISO) - the most commonly used anesthetic nowadays - and its use in prolonged in vivo rodent studies using imaging modalities, such as magnetic resonance imaging (MRI). It also presents established evidence for normal ranges of global and regional physiological cardiac function
