Anesthesia

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

  • Local and Regional
  • General
  • Sedation

Anesthesia 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 anesthesia has helped anesthesiologists in the progression of patient safety before and after surgery and medical procedures. The developments and research of anesthesia 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 anesthesia, it allows anesthesiologists to improve the delivery of patient safety while unconscious.

101. Tattoos and administration of regional anesthesia: a comprehensive systematic review protocol. (PubMed)

Tattoos and administration of regional anesthesia: a comprehensive systematic review protocol. The review question is what is the impact of tattoos on the administration of regional anesthesia?The quantitative objective is to identify and quantify the risks to a patient when advancing a needle through tattooed skin for the purpose of administering a regional anesthetic.The qualitative objective is to investigate anesthesia providers' perceptions and experiences when presented with a patient (...) and/or a surgeon requests for a regional anesthetic that would require needle trespass through tattooed skin. An additional qualitative objective is to identify the thoughts, opinions and biases related to the administration of a regional anesthetic through tattooed skin from the perspective of the patient, anesthesia provider, surgeon or other affected parties (e.g. patient families, hospital or clinic administrators or insurance providers).

102. Opioid use after propofol or sevoflurane anesthesia: a randomized trial

Opioid use after propofol or sevoflurane anesthesia: a randomized trial The intravenous anesthetic propofol is a gamma-aminobutyric acid A receptor agonist. Propofol promotes analgesia by depressing nociceptive transmission in peripheral neurons, antagonizing N-methyl-D-aspartate receptors, and activating gamma-aminobutyric acid A receptors in dorsal root ganglion receptor cells. Nevertheless, it remains unclear whether intraoperative propofol causes clinically meaningful postoperative (...) analgesia. We therefore tested the hypothesis that patients anesthetized with sevoflurane require a greater quantity of postoperative opioids (from the end of surgery until the next postoperative morning) than those anesthetized with propofol.With Institutional Review Board and EudraCT Number approval (2009-011038-82) and patients' informed consent, ninety patients scheduled for open vein stripping were randomized to either sevoflurane or propofol anesthesia at the Medical University of Vienna General

103. Preemptive Local Anesthesia in Ankle Arthroscopy

Preemptive Local Anesthesia in Ankle Arthroscopy Complex anesthesia is increasingly used in order to reduce postoperative pain and accelerate rehabilitation. The aim of this study was to evaluate the efficacy and safety of preemptive local anesthesia combined with general or spinal anesthesia in ankle arthroscopy.From January 2014 to February 2016, 80 ankle anterior arthroscopies were performed. Patients were randomly assigned to one of 4 groups, depending on the type of anesthesia: A, general (...) and local preemptive; B, spinal and local preemptive; C, general and placebo; D, spinal and placebo. After general or spinal anesthesia, each patient randomly received an injection of 7 mL of a mixture of local anesthetics or the same amount of normal saline. After 2, 4, 8, 12, 16, 24, 48, and 72 hours following the release of the tourniquet, the pain intensity level was measured with a visual analog scale (VAS). The use of additional analgesics and any adverse effects were also noted.Preemptive local

Isiris: A Novel Method of Removing Foreign Bodies from the Lower Urinary Tract to Avoid Unnecessary Hospitalization and Anesthesia Polyembolokoilamania refers to the practice of inserting foreign bodies (FBs) into natural orifices. A FB within the urethra is a relatively rare phenomenon with 646 cases recorded last year in the United Kingdom. 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. The procedure was performed within the ED, without the need for admission to a ward bed or general anesthesia. Furthermore, only two members of staff were required to remove all of the urethral FBs.Isiris, although marketed as a stent

The effect of music on the level of cortisol, blood glucose and physiological variables in patients undergoing spinal anesthesia. Surgical procedures performed using spinal anesthetic techniques present a special challenge to anesthesiologists, because patients are awake and are exposed to multiple anxiety provoking visual and auditory stimuli.

Unilateral paravertebral block compared with subarachnoid anesthesia for the management of postoperative pain syndrome after inguinal herniorrhaphy: a randomized controlled clinical trial Inguinal herniorrhaphy is a common surgical procedure. The aim of this investigation was to determine whether unilateral paravertebral block could provide better control of postoperative pain syndrome compared with unilateral subarachnoid block (SAB). A randomized controlled study was conducted using 50 (...) patients with unilateral inguinal hernias. The patients were randomized to receive either paravertebral block (S group) or SAB (C group). Paravertebral block was performed by injecting a total of 20 mL of 0.5% levobupivacaine from T9 to T12 under ultrasound guidance, whereas SAB was performed by injecting 13 mg of 0.5% levobupivacaine at the L3 to L4 level.
