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.

631. Local anaesthetic on Filshie clips for pain relief after tubal sterilisation: a randomised double-blind controlled trial. (Abstract)

Local anaesthetic on Filshie clips for pain relief after tubal sterilisation: a randomised double-blind controlled trial. Pain during tubal sterilisation is thought to be due to either ischaemia or pressure at the site of impact of sterilising devices on the fallopian tubes. We have evaluated the effectiveness of an application of 2% lignocaine gel to Filshie clips to relieve postoperative pain. In a randomised double-blind placebo-controlled study, 80 healthy women undergoing tubal (...) sterilisation under general anaesthesia at the County Hospital, Lincoln, UK, were allocated to be sterilised by Flishie clips covered with 2% lignocaine gel or K-Y gel as placebo. Pelvic pain was assessed, with a 100 mm visual analogue scale, at 1 hour, at hospital discharge, and time of first analgesia or any other time analgesia was demanded. The lignocaine-treated group had significantly longer time to first analgesia, less pain at 1 hour, less nausea and vomiting, and shorter recovery time. Fewer

632. Prevention of atelectasis during general anaesthesia. (Abstract)

Prevention of atelectasis during general anaesthesia. Atelectasis is an important cause of impaired gas exchange during general anaesthesia; it causes pulmonary shunting. We studied the effects of gas composition on the formation of atelectasis and on gas exchange during the induction of general anaesthesia. In 12 adult patients, the lungs were ventilated with 30% oxygen in nitrogen during anaesthesia induction, and in another 12, a conventional technique was used (100% oxygen during induction (...) and 40% oxygen in nitrogen thereafter). Extent of atelectasis was estimated by computed tomography and the ventilation-perfusion relation (VA/Q) by the multiple inert gas elimination technique. After anaesthesia induction, there was little atelectasis in the 30% oxygen group (mean 0.2 [SD 0.4] cm2) and a significantly greater amount (4.2 [5-6] cm2; p < 0.001) in the 100% oxygen group. Patients in the 30% oxygen group were observed for another 40 min. 6 continued to receive 30% oxygen (subgroup
