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.

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 (...) %; P< .0001). Recovery room vomiting, airway obstruction, respiratory depression, sedation, emergence time, time spent in the recovery room as well as total intraoperative fentanyl administration, hypnotic parameters, and incidence of intraoperative movement were not different between groups.Patients receiving intraoperative ANI-guided fentanyl administration during sevoflurane anesthesia for lumbar discectomy and laminectomy demonstrated decreased pain in the recovery room, likely as a result
Effectiveness of preoperative intranasal dexmedetomidine, compared with oral midazolam, for the prevention of emergence delirium in the pediatric patient undergoing general anesthesia: a systematic review. Emergence delirium is defined as a cognitive disturbance during emergence from general anesthesia resulting in hallucinations, delusions and confusion manifested by agitation, restlessness, involuntary physical movement and extreme flailing in bed. Postoperative emergence delirium develops (...) in 12% to 18% of all children undergoing general anesthesia for surgery. This post-anesthetic phenomenon changes cognitive and psychomotor behavior, and puts pediatric patients and health care personnel at risk of injury. A newer drug, dexmedetomidine, is a selective alpha-2 agonist, which works in the brain and spinal cord that has sedative, analgesic and anxiolytic properties. Dexmedetomidine also has the ability to lower the overall anesthetic requirements by reducing sympathetic outflow
Safety Aspects of Postanesthesia Care Unit Discharge without Motor Function Assessment after Spinal Anesthesia: A Randomized, Multicenter, Semiblinded, Noninferiority, Controlled Trial Postanesthesia care unit (PACU) discharge without observation of lower limb motor function after spinal anesthesia has been suggested to significantly reduce PACU stay and enhance resource optimization and early rehabilitation but without enough data to allow clinical recommendations.A multicenter, semiblinded (...) , noninferiority randomized controlled trial of discharge from the PACU with or without assessment of lower limb motor function after elective total hip or knee arthroplasty under spinal anesthesia was undertaken. The primary outcome was frequency of a successful fast-track course (length of stay 4 days or less and no 30-day readmission). Noninferiority would be declared if the odds ratio (OR) for a successful fast-track course was no worse for those patients receiving no motor function assessment versus those

Liposomal Bupivacaine May Prove to Provide Adequate Long-Term Local Anesthesia UTCAT3208, Found CAT view, CRITICALLY APPRAISED TOPICs University: | | ORAL HEALTH EVIDENCE-BASED PRACTICE PROGRAM View the CAT / Title Liposomal Bupivacaine May Prove to Provide Adequate Long-Term Local Anesthesia Clinical Question Is liposomal bupivacaine (Exparel) effective in providing extended local anesthesia and reducing post-operative opioid use in a variety of dental procedures? Clinical Bottom Line (...) For patients receiving endodontic care or third molar extractions, there is not enough evidence to support the conclusion that liposomal bupivacaine is any more effective than other anesthesia medications. This is supported by a randomized double-blinded study in which buccal infiltration of liposomal bupivacaine was shown to not achieve clinically relevant levels of anesthesia for prolonged periods of time. A systematic review of liposomal bupivacaine showed inconclusive evidence to support that liposomal
