The delivery of anesthesia to surgical patients is safer today than ever before. Advancements in technology such as end tidal carbon dioxide monitoring, oxygen saturation monitoring, video laryngoscopy and safer medication profiles are just a few examples in the realm of anesthesia that assist in protecting patients from potential harm. As the face of healthcare payments change into a patient-satisfaction and outcomes-driven model, it is important for the specialty of anesthesia to continue to find ways to keep patients safer by examining current accepted practices in anesthesia and challenging and changing practices that continue to place patients at risk for harm.
One of the most common procedures performed in U.S. hospitals is the transfusion of red blood cells (RBC). One in every ten patients in U.S. hospitals will receive one or more units of RBC during a hospitalization.1 There are well known risks that anesthesia providers are aware of when patients receive allogeneic blood transfusions such as allergic reactions and fluid volume overloads. The not-so-obvious risks of RBC transfusion involve immunodilution factors that increase incidence of post-operative infections and a higher overall mortality. A meta-analysis of pooled results from multiple observational studies, each of which varies for risks between patients, shows patients receiving allogeneic blood transfusions have an 88% higher mortality, 69% higher infection rate, and 250% higher rate of ARDS.2 All intraoperative transfusions should be placed through a risk-benefit analysis by the medical provider.
The purpose of this paper is to examine current research results concerning technology that indicates it may decrease the incidence of unnecessary intraoper...

This single case study describes a patient undergoing cardiac surgery that subsequently required extracorporeal membrane support after falling into severe cardiogenic shock. The Radical-7 device was utilized to continually monitor Hb levels. These levels were compared to bedside POC results from invasive blood sampling methods. It was discovered that the spectrophotometric monitor showed statistically comparable Hb levels as compared with the invasive POC monitor. It was considered that the Masimo device is a viable alternative for invasive testing in this complex situation. (Level 6).
Inadvertent perioperative hypothermia is a common anesthesia-related complication with reported prevalence ranging from 50% to 90%.(ref 3,4 of 4) The clinical consequences of perioperative hypothermia include tripling the risk of morbid myocardial outcomes and surgical wound infections, increased blood loss and transfusion requirements, and prolonged recovery and hospitalization.(ref 5)
“Technological advancements in anesthesia practice: Role of decision support system.” Anesthesia: Essays and Researches. January 8, 2014. Web. October 23, 2015. There have been many advancements in technology in the anesthesia field. A recent major advancement has been the decision support system (DSS). The decision support system acts similar to a second human central nervous system, and receives as well as relays information to and from the patient and the anesthesia information management system (AIMS). The DSS helps to maintain the data coming into and out of the patient during a medical procedure. The DSS also provides help during a medical crisis, giving the physicians a solution if an intra-operation (during the operation) crisis happens. The DSS can also design various scenarios for pre, intra, and post operation scenarios for the anesthesiologist to prepare for based on that patient’s medical history, information, and
This essay describes how the anaesthetic machine and airway management equipment are prepared in operating theatres and discusses how they are ensured safe for use. It evaluates the Association of Anaesthetists of Great Britain and Ireland (AAGBI) guidelines related to safe practice and the preparation of the ET tubes, laryngeal masks, guedels, Naso pharyngeal airways and the laryngoscope. The function of the anaesthetic workstation is to deliver a mixture of anaesthetic agents and gases safely to the patient during the induction process and throughout surgery. In addition, it also provides ventilation to support breathing and monitors the patient’s vital signs to minimise the anaesthetic risks to the patient whilst in the care of health professionals. The pre-use check is vital to patient safety as an inadequate check of the anaesthetic machine or airway management equipment can and does lead to significant harm of the patient including mortality (Medicines and Healthcare Products Regulatory Agency (MHRA), 2008 and Magee, 2012).
2) “It’s difficult to determine who provides anesthesia care in the studies and the number of cases that actually involved a physician anesthesiologist (p. 11)” the ASA is claiming that the data collected and used in this review, are difficult to determine who did what and when. In other words it is unclear as to who was performing and providing care in these studies and very well could be, the care provided by an anesthesiologist. They say also that the data provided and used by the study has limiting factors to determine whether an anesthesiologist was available as needed, for rescue or advice by a patient being treated by a nurse anesthetist if they were to experience complications under the
A complete blood count was done for this patient upon admission in order to give a baseline to help guide his care. The blood count was also done to show how his hematological system was affected by the trauma that he suffered in the motor vehicle accident he was in. If the patient was hemodynamically unstable, he may have needed blood transfusions to bring his blood counts up. White blood cells could help to tell is the patient has an infection in his surgical wound. The patient also underwent surgery to correct the injury to his spine, causing more blood to be lost in the process. The platelet, hemoglobin, and hematocrit counts could help to show in the future if the patient is suffering from internal bleeding after the surgery he had.
A cardiac assessment: Listen to heart sounds listening for extra heart sounds, fast heartbeat, and monitor EKG looking for dysthymias. Assess vitals especially BP, BP should be kept low in heart failure patients to put less stress on the heart. Assess the patient for edema as a result of fluid retention. Listen for crackles in the lungs due to fluid built up. Watch I&O’s and weight the patient to assess for edema, ask about activity intolerance. Assess for changes in mental status, cool extremities, pale or cyanotic, fatigue, and JVD (Indications of poor perfusion) (Ignatavicius &Workman, p.756).
This essay will discuss the risks for patients during the preoperative, intraoperative and postoperative stages of the perioperative journey and how both patients and healthcare professionals involved in the perioperative stages can work together to prevent perioperative hypothermia.

As CO Casteel performed CPR on MOODY, CO Dodson arrived back in the cell with a pulse oximetry meter and placed it on MOODY’S right index finger. According to CO Casteel, the pulse oximetry meter reading indicated MOODY’S peripheral oxygen saturation was at 72 percent. After noting MOODY’S peripheral oxygen saturation, CO Casteel resumed CPR on MOODY as Regional Paramedical Service (RPS) personnel entered the cell and joined his efforts to revive

Anesthesia is used in almost every single surgery. It is a numbing medicine that numbs the nerves and makes the body go unconscious. You can’t feel anything or move while under the sedative and are often delusional after being taken off of the anesthetic. Believe it or not, about roughly two hundred years ago doctors didn’t use anesthesia during surgery. It was rarely ever practiced. Patients could feel everything and were physically held down while being operated on. 2It wasn’t until 1846 that a dentist first used an anesthetic on a patient going into surgery and the practice spread and became popular (Anesthesia). To this day, advancements are still being made in anesthesiology. 7The more scientists learn about molecules and anesthetic side effects, the better ability to design agents that are more targeted, more effective and safer, with fewer side effects for the patients (Anesthesia). Technological advancements will make it easier to read vital life signs in a person and help better decide the specific dosages a person needs.

Individuals need to understand the use of anesthesia always comes with risks. In most cases, however, it's safe when administered by someone with the proper training. Certain individuals, such as those with obstructive sleep apnea or ones who are obese, need to speak to their physician before being sedated, as their risk of complications is higher.
