Preanesthetic assessment

Last updated

Preanesthetic assessment (also called Preanesthesia evaluation, Pre-anesthesia checkup (PAC) or simply Preanesthesia) is a medical check-up and laboratory investigations done by an anesthesia provider or a registered nurse before an operation, to assess the patient's physical condition and any other medical problems or diseases the patient might have. [1] The goal of the assessment is to identify factors that significantly increase the risk of complications, and modify the procedure appropriately. [2] [3] The aim is to identify the appropriate anesthetic techniques to be used, to ensure the safety of perioperative care, optimal resource use, improved outcomes, and patient satisfaction, while considering the individual and person related risk factors and circumstances. [4] The preanesthetic assessment involves the consideration of information from various sources that include the past medical records, interview, physical examination, as well as results from medical and laboratory tests. [5]

General recommendations have been published in the USA [6] and in India. [7]

A mnemonic has been suggested for pre-anesthetic assessment, to ensure that all aspects are covered. [8] It runs alphabetically:

A - Affirmative history; Airway
B - Blood hemoglobin, blood loss estimation, and blood availability; Breathing
C - Clinical examination; Co-morbidities
D - Drugs being used by the patient; Details of previous anesthesia and surgeries
E - Evaluate investigations; End point to take up the case for surgery
F - Fluid status; Fasting
G - Give physical status; Get consent

A respiratory therapist is a specialized healthcare practitioner trained in critical care and cardio-pulmonary medicine in order to work therapeutically with people who have acute critical conditions, cardiac and pulmonary disease. Respiratory therapists graduate from a college or university with a degree in respiratory therapy and have passed a national board certifying examination. The NBRC is responsible for credentialing as a CRT, or RRT,

Anesthesia State of medically-controlled temporary loss of sensation or awareness

Anesthesia is a state of controlled, temporary loss of sensation or awareness that is induced for medical purposes. It may include some or all of analgesia, paralysis, amnesia, and unconsciousness. A person under the effects of anesthetic drugs is referred to as being anesthetized.

Sedation is the reduction of irritability or agitation by administration of sedative drugs, generally to facilitate a medical procedure or diagnostic procedure. Examples of drugs which can be used for sedation include isoflurane, diethyl ether, propofol, etomidate, ketamine, pentobarbital, lorazepam and midazolam.

Anesthesiology Medical specialty concerned with anesthesia and perioperative care

Anesthesiology, anaesthesiology, or anaesthesia is the medical specialty concerned with the total perioperative care of patients before, during and after surgery. It encompasses anesthesia, intensive care medicine, critical emergency medicine, and pain medicine. A physician specialized in anesthesiology is called an anesthesiologist, anaesthesiologist, or anaesthetist, depending on the country. In some countries, the terms are synonymous, while in other countries they refer to different positions and anesthetist is only used for non-physicians, such as nurse anesthetists.

Physical examination Process by which a medical professional investigates the body of a patient for signs of disease

In a physical examination, medical examination, or clinical examination, a medical practitioner examines a patient for any possible medical signs or symptoms of a medical condition. It generally consists of a series of questions about the patient's medical history followed by an examination based on the reported symptoms. Together, the medical history and the physical examination help to determine a diagnosis and devise the treatment plan. These data then become part of the medical record.


Awareness under anesthesia, also referred to as intraoperative awareness or accidental awareness during general anesthesia (AAGA), is a rare complication of general anesthesia where patients regain varying levels of consciousness during their surgical procedures. While anesthesia awareness is possible without resulting in any long-term memory, it is also possible for the victim to have awareness with explicit recall, where victims can remember the events related to their surgery.

Nurse anesthetist Nurse trained to provide anaesthesia care

A nurse anesthetist is an advanced practice nurse who administers anesthesia for surgery or other medical procedures. They are involved in the administration of anesthesia in a majority of countries, with varying levels of autonomy.

A post-anesthesia care unit, often abbreviated PACU and sometimes referred to as post-anesthesia recovery or PAR, or simply Recovery, is a vital part of hospitals, ambulatory care centers, and other medical facilities. Patients who received general anesthesia, regional anesthesia, or local anesthesia are transferred from the operating room suites to the recovery area. The patients are monitored typically by anesthesiologists, certified registered nurse anesthetists, and other medical staff. Providers follow a standardized handoff to the medical PACU staff that includes, which medications were given in the operating room suites, how hemodynamics were during the procedures, and what is expected for their recovery. After initial assessment and stabilization, patients are monitored for any potential complications, until the patient is transferred back to their hospital rooms.

Anesthetic technician

An anesthetic technician is an allied healthcare worker who performs a patient care role predominantly assisting with the administration and monitoring of anesthesia and has an extensive knowledge of anesthesia techniques, instruments, supplies and technology.

The ASA physical status classification system is a system for assessing the fitness of patients before surgery. In 1963 the American Society of Anesthesiologists (ASA) adopted the five-category physical status classification system; a sixth category was later added. These are:

  1. Healthy person.
  2. Mild systemic disease.
  3. Severe systemic disease.
  4. Severe systemic disease that is a constant threat to life.
  5. A moribund person who is not expected to survive without the operation.
  6. A declared brain-dead person whose organs are being removed for donor purposes.

In the United States, anesthesia can be administered by physician anesthesiologists, an anesthesiologist assistant, or nurse anesthetist.

Pelvic examination Physical medical examination

A pelvic examination is the physical examination of the external and internal female pelvic organs. It is frequently used in gynecology for the evaluation of symptoms affecting the female reproductive and urinary tract, such as pain, bleeding, discharge, urinary incontinence, or trauma. It can also be used to assess a woman's anatomy in preparation for procedures. The exam can be done awake in the clinic and emergency department, or under anesthesia in the operating room. The most commonly performed components of the exam are 1) the external exam, to evaluate the external genitalia 2) the internal exam with palpation to examine the uterus, ovaries, and fallopian tubes, and 3) the internal exam using the speculum to visualize the vaginal walls and cervix. During the pelvic exam, sample of cells and fluids may be collected to screen for sexually transmitted infections or cancer.

Veterinary anesthesia is anesthesia performed on non-human animals by a veterinarian or a Registered Veterinary Technician. Anesthesia is used for a wider range of circumstances in animals than in people, due to animals' inability to cooperate with certain diagnostic or therapeutic procedures. Veterinary anesthesia includes anesthesia of the major species: dogs, cats, horses, cattle, sheep, goats, and pigs, as well as all other animals requiring veterinary care such as birds, pocket pets, and wildlife.

Perianesthesia nursing is a nursing specialty practice area concerned with providing nursing care to patients undergoing or recovering from anesthesia. Perianesthesia nursing encompasses several subspecialty practice areas and represents a diverse number of practice environments and skill sets.

In the United States, certified anesthesiologist assistants (CAAs) are clinicians that practice medicine under the direction of licensed anesthesiologists to implement anesthesia care plans for a patient undergoing surgery. CAAs are integral members of the anesthesia care team as described by the American Society of Anesthesiologists (ASA). All CAAs possess a baccalaureate degree, and complete an intensive didactic and clinical program at a postgraduate level. CAAs are trained in the delivery and maintenance of all types of anesthesia care as well as advanced patient monitoring techniques. The goal of CAA education is to guide the transformation of student applicants into competent clinicians.
