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.

41. Effect of local anesthetic volume (20 mL vs 30 mL ropivacaine) on electromyography of the diaphragm and pulmonary function after ultrasound-guided supraclavicular brachial plexus block: a randomized controlled trial (Abstract)

Effect of local anesthetic volume (20 mL vs 30 mL ropivacaine) on electromyography of the diaphragm and pulmonary function after ultrasound-guided supraclavicular brachial plexus block: a randomized controlled trial Diaphragmatic paralysis following supraclavicular brachial plexus block (SCBPB) is ascribed to phrenic nerve palsy. This study investigated the effect of 2 volumes of 0.375% ropivacaine on efficacy of block as a surgical anesthetic and as an analgesic and examined diaphragm compound (...) muscle action potentials (CMAPs) and pulmonary function before and after SCBPB.Eighty patients scheduled for removal of hardware for internal fixation after healing of an upper limb fracture distal to the shoulder were randomized to receive ultrasound-guided SCBPC for surgical anesthesia with 20 mL (Group A) or 30 mL (Group B) 0.375% ropivacaine. The latency and amplitude of diaphragm CMAPs and forced vital capacity (FVC), FVC% predicted, and forced expiratory volume in 1 s (FEV1) were measured

42. Onset Time of Local Anesthesia After Single Injection in Toe Nerve Blocks: A Randomized Double-Blind Trial. (Abstract)

Onset Time of Local Anesthesia After Single Injection in Toe Nerve Blocks: A Randomized Double-Blind Trial. The study was conducted to investigate the onset time and safety profile of four different local anesthetic solutions.Randomized controlled clinical trial study.One hundred twelve healthy volunteers were assigned to receive digital block on their second toe. Individuals were randomly assigned to one of the following groups: lidocaine 2%, lidocaine 2% with epinephrine, bupivacaine 0.5 (...) %, or bupivacaine 0.5% with epinephrine. Onset time was measured until detecting the absence of pinprick sensation. Oxygen saturation was measured in the infiltrated toe up to 60 minutes.The subjects in the groups of anesthetics with epinephrine had a significantly lower mean onset time. There were no significant differences regarding oxygen saturation between the groups and no adverse effects were recorded.The use of anesthetics with epinephrine can be an effective form of local anesthetic for digital blocks

44. Effect of Benson Relaxation on the Intensity of Spinal Anesthesia-Induced Pain After Elective General and Urologic Surgery. (Abstract)

Effect of Benson Relaxation on the Intensity of Spinal Anesthesia-Induced Pain After Elective General and Urologic Surgery. The present study aimed to evaluate the effect of Benson's muscle relaxation on postoperative spinal anesthesia-induced pain.Randomized clinical trial.Sixty-four patients were randomly assigned to intervention and control groups. Benson's muscle relaxation was performed on the intervention group for 10 to 20 minutes based on the patients' tolerance. Before and after (...) the intervention, the two groups were assessed using the visual analog scale and compared. SPSS version 23 was used to analyze data.The mean pain score in the control group before and after the intervention was 5.34 and 5.62, respectively (P < .003), and in the intervention group, 5.28 and 4.03, respectively (P < .001).Benson's relaxation technique effectively influenced the intensity of postoperative spinal anesthesia-induced pain. Therefore, it can be used by nurses as a safe, simple, and inexpensive

Liposomal Bupivacaine Versus Standard Periarticular Injection in Total Knee Arthroplasty With Regional Anesthesia: A Prospective Randomized Controlled Trial Liposomal bupivacaine (Exparel) is a long-acting local anesthetic preparation with demonstrated efficacy over placebo in reducing postoperative pain and opioid requirement. Limited comparative efficacy and cost-effectiveness data exist for its use in total knee arthroplasty (TKA) when used in a multimodal, opioid-sparing analgesic (...) and anesthetic approach. We hypothesized that liposomal bupivacaine offers no clinical advantage over our standard of care but carries significant economic impact.This is a prospective, randomized, single-blinded, controlled trial comparing liposomal bupivacaine periarticular injection (PAI) to our current approach including conventional bupivacaine PAI, in the setting of regional anesthesia. All adult unilateral TKA patients of the collaborating surgeon were eligible to participate in the study. Patients

Effects of fascia iliaca compartment block combined with general laryngeal mask airway anesthesia in children undergoing femoral fracture surgery: a randomized trial Postoperative agitation after general anesthesia is a common complication in children; however, pain or uncomfortable feeling is the main reason of emergence agitation. Here, we have investigated the effects of fascia iliaca compartment block (FICB) combined with general laryngeal mask airway (LMA) anesthesia in children undergoing (...) femoral surgery.Eighty children undergoing femoral surgery were randomly divided into two groups: FICB + LMA group and control group (n=40). The FICB + LMA group received FICB combined with general LMA anesthesia, and the control group received tracheal intubation general anesthesia alone. Anesthesia was maintained with nitrous oxide and sevoflurane. Hemodynamic parameters were monitored, and pain was assessed by verbal numeric score within 24 hours postoperatively.
