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
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.

Anesthetic Cream Use During Office Pessary Removal and Replacement: A Randomized Controlled Trial To estimate the effect of lidocaine-prilocaine cream on patient pain at the time of office pessary removal and reinsertion.In this double-blind, randomized placebo-controlled trial, participants undergoing routine pessary care in a urogynecology office at a tertiary referral center were randomized to application of 4 g of either lidocaine-prilocaine or placebo cream 5 minutes before pessary change
Perioperative Management of Elderly Patients with Gastrointestinal Malignancies: The Contribution of Anesthesia Elderly patients suffering from gastrointestinal malignancies are particularly prone to perioperative complications. Elderly patients often present with reduced physiological reserves, and comorbidities can limit treatment options and promote complications. Surgeons and anesthesiologists must be aware of strategies required to deal with this vulnerable subgroup.We provide a brief
Techniques for preventing hypotension during spinal anaesthesia for caesarean section. Maternal hypotension is the most frequent complication of spinal anaesthesia for caesarean section. It can be associated with nausea or vomiting and may pose serious risks to the mother (unconsciousness, pulmonary aspiration) and baby (hypoxia, acidosis, neurological injury).To assess the effects of prophylactic interventions for hypotension following spinal anaesthesia for caesarean section.We searched (...)

Intraoperative "Analgesia Nociception Index"-Guided Fentanyl Administration During Sevoflurane Anesthesia in Lumbar Discectomy and Laminectomy: A Randomized Clinical Trial The "Analgesia Nociception Index" (ANI; MetroDoloris Medical Systems, Lille, France) is a proposed noninvasive guide to analgesia derived from an electrocardiogram trace. ANI is scaled from 0 to 100; with previous studies suggesting that values ≥50 can indicate adequate analgesia. This clinical trial was designed (...) to investigate the effect of intraoperative ANI-guided fentanyl administration on postoperative pain, under anesthetic conditions optimized for ANI functioning.Fifty patients aged 18 to 75 years undergoing lumbar discectomy or laminectomy were studied. Participants were randomly allocated to receive intraoperative fentanyl guided either by the anesthesiologist's standard clinical practice (control group) or by maintaining ANI ≥50 with boluses of fentanyl at 5-minute intervals (ANI group).

BACKGROUND This document applies to accredited departments of anaesthesia. These departments provide the majority of training within the ANZCA training program. They should be adequately staffed to provide this training, particularly in regard to providing adequate supervision of trainees. The department must provide a safe high quality clinical service and be able to effectively manage the service. Consequently, though the document primarily addresses anaesthesia staff
of 'medication errors' range from 1 in 20 administration events 1 , to 1 in 133 2 anaesthesia episodes. Many of these reported events were protocol or process errors (including mislabelling or omission of an appropriate drug), however a proportion of these errors will result in an adverse event for the patient. More than 3 million anaesthetics are administered in Australia and New Zealand annually suggesting a substantial contribution to iatrogenic adverse events. Anaesthetists must be aware (...) anaesthetics. 5.2.2 Anaesthesia drug drawers and workspace should be organised formally with attention to orderliness and the position of ampoules. Where possible drugs of the same class should be stored in adjacent compartments. Standardisation within each institution, and ideally, each region, is highly desirable. 5.2.3 Many drugs used in anaesthesia are hazardous if inadvertently administered. It is important to separate drugs which are potent, and less frequently used, often emergency drugs, from those

Comparative experimental study on two designed intravenous anaesthetic combinations in dogs The goal of the present study is to design a good anaesthetic program for dogs which can lead to optimal anaesthesia with no or minimal post-operative adverse effects. For this purpose, we designed two anaesthetic combinations and compared their effects in Mongrel dogs: combination 'A' consisting of atropine, xylazine, ketamine plus propofol, and combination 'B' consisting of atropine, diazepam, ketamine (...) plus propofol. The onset and duration of anaesthesia induction, the duration of maintenance as well as the period of recovery were recorded and compared for both combinations. Furthermore, heart rate, respiratory rate, body temperature as well as blood picture were analyzed before and after administration of the proposed anaesthetic regimens. Administration of combination 'A' lead to rapid onset, within seconds, and induction of anaesthesia. The anaesthetic effect was maintained for approximately
