Which medication is administered intravenously for anaphylaxis when it occurs under general anesthesia?

Other medications, such as antihistamines and steroids, may help alleviate symptoms but will not fully and effectively treat an anaphylactic reaction. In the operating room, an anesthesiologist administers epinephrine by intravascular injection through an intravenous line (IV).

Which one of the following medications is administered intravenously as soon as a serious allergic reaction is confirmed?

Epinephrine — Epinephrine is the first and most important treatment for anaphylaxis, and it should be administered as soon as anaphylaxis is recognized to prevent the progression to life-threatening symptoms as described in the rapid overviews of the emergency management of anaphylaxis in adults (table 1) and children ...

Which medication's is are given to treat a febrile Nonhemolytic transfusion reaction to incompatible blood?

Febrile non-hemolytic and allergic reactions are the most common transfusion reactions, but usually do not cause significant morbidity. In an attempt to prevent these reactions, US physicians prescribe acetaminophen or diphenhydramine premedication before more than 50% of blood component transfusions.

Which is the postoperative phase of general anesthesia?

Postoperative Period After awakening, patients typically recover in the post anesthesia care unit (PACU). In more critically ill patients, recovery may occur directly in the intensive care unit. Patients recover in the recovery unit until they have met PACU discharge criteria.

Which of the following is the treatment of choice for an anaphylactic reaction?

Epinephrine (Adrenaline, EpiPen, EpiPen Jr, Twinject, Adrenaclick) Epinephrine is the drug of choice for treating anaphylaxis.

What is the protocol for the treatment of anaphylaxis?

Epinephrine (1 mg/ml aqueous solution [1:1000 dilution]) is the first-line treatment for anaphylaxis and should be administered immediately. In adults, administer a 0.3 mg intramuscular dose using a premeasured or prefilled syringe, or an autoinjector, in the mid-outer thigh (through clothing if necessary).

What is the treatment for hemolytic transfusion reaction?

If a person develops an acute hemolytic transfusion reaction, the doctor or nurse will stop the transfusion. Treatment depends on the severity of the reaction and may include: IV fluids. dialysis.

How is a febrile transfusion reaction treated?

Stop the transfusion immediately and follow other steps for managing suspected transfusion reactions. Treat the fever with an antipyretic. However, avoid aspirin in thrombocytopenic and paediatric patients. Consider and exclude other causes, as fever alone may be the first manifestation of a life-threatening reaction.

What is febrile Nonhemolytic transfusion reaction?

Febrile nonhemolytic transfusion reactions (FNHTRs) are common, occurring with 1–3% of transfusions. FNHTR manifests as fever and/or chills without hemolysis occurring in the patient during or within 4 hours of transfusion cessation. Diagnosis is made by excluding other causes of fever.

What are the 4 stages of general anesthesia?

Stages of General AnesthesiaStage 1: Induction. The earliest stage lasts from when you first take the medication until you go to sleep. ... Stage 2: Excitement or delirium. ... Stage 3: Surgical anesthesia. ... Stage 4: Overdose.

What are the 3 postoperative phases?

The recovery from major surgery can be divided into three phases: (1) an immediate, or post anesthetic, phase; (2) an intermediate phase, encompassing the hospitalization period; and (3) a convalescent phase.

What are the 3 phases of anesthesia?

It can be divided into three stages: induction, main- tenance and emergence. In regional anaesthesia, nerve transmis- sion is blocked, and the patient may stay awake or be sedated or anaesthetized dur- ing a procedure.

How to tell if you have a MH?

Clinical symptoms of MH are highly variable, and range from abortive courses with mild or moderate symptoms to fulminant MH crises with severe skeletal muscle hypermetabolism and rhabdomyolysis. Excessive CO2production presenting with an increase in end tidal CO2concentration or hyperventilation while breathing spontaneously is a sensitive and specific early sign of imminent MH. An abrupt rise in end tidal CO2may occur simultaneously with administration of succinylcholine.7,54Further early symptoms of an MH crisis may include tachycardia, supraventricular or ventricular arrhythmia, and isolated masseter spasm or generalized muscular rigidity. 50–80% of patients develop arrythmia or muscular reactions.53Nonspecific sinus tachycardia might be misinterpreted as inadequate anesthesia, which often delays the diagnosis of MH. Distinctive cyanosis indicating increased oxygen consumption may occur later in the course of an MH episode. A rapid increase in temperature (to >38.8°C) is a relatively late sign. However, a rapid increase of >1°C in 15 minutes is diagnostically more relevant than the peak temperature.22,55In some cases, there are no relevant changes in body temperature, particularly if adequate treatment is started early.56,57Arterial blood gas analyses reveal a combination of respiratory and metabolic acidosis with negative base excess, lactemia, hypercapnia, and hypoxemia. Fulminant MH crisis usually presents with paCO2values >60 mmHg and a base excess of >8 mVal/L. As the MH episode progresses, rhabdomyolysis leads to hyperkalemia, increased creatine phosphokinase, and myoglobinemia, and might result in acute renal failure. The end stage of a fulminant MH crisis is characterized by multiorgan failure and circulatory collapse (Table 1).7

What happens to the MH crisis?

In an MH crisis, the triggering agent induces prolonged opening of functionally altered ryanodine receptors, resulting in uncontrolled release of calcium from the sarcoplasmic reticulum and ongoing muscle activation presenting as rigid ity.24–27Additionally, constant activation of aerobic and anaerobic metabolism results in increased oxygen consumption, leading to hypoxia, progressive lactate acidosis, excessive production of CO2, and increased body temperature (Figure 1).

Does nitrous oxide trigger MH?

It is well accepted that all volatile halogenated inhalational anesthetics (eg, halothane, enflurane, isoflurane, desflurane, sevoflurane) have the potential to induce an MH crisis in MHS individuals.41Studies in MHS pigs and in vitro studies indicate that nitrous oxide and the noble gas xenon do not trigger MH.42–45Further, it is important to mention that exposure to volatile anesthetics does not inevitably lead to MH. Several patients have reported a number of uneventful anesthesias before an MH episode occurred. Triggering MH might be in part a dose-dependent phenomenon, which is consistent with the interindividual variability and graded incremental contracture response of MHS muscle during the in vitro contracture test.20The trigger potency of the depolarizing muscle relaxant succinylcholine has been unclear for a long time, although there is no doubt that this substance enhances an MH reaction and decreases the likelihood of survival in patients who receive a combination of succinylcholine and a volatile anesthetic, compared with a volatile anesthetic alone.6,20However, two recent retrospective studies reported a number of cases in which succinylcholine was the sole trigger of an MH event.18,46Over the years, several drugs have been suspected to cause MH. However, in vitro and in vivo studies of serotonergic drugs, phosphodiesterase type III inhibitors, and ondansetron have not provided convincing evidence of their propensity to act as MH triggers.20,47

What happens when calcium is reuptaken into the sarcoplasmic reticulum?

Calcium reuptake into the sarcoplasmic reticulum and sustained muscle contraction consume large amounts of adenosine triphosphate. Depletion of cellular adenosine triphosphate stores leads to protracted muscular rigidity and finally to rhabdomyolysis, when breakdown of membrane integrity results in release of the contents of cells (eg, potassium, creatine phosphokinase, myoglobin) into the circulation.7,28

What is the action potential of acetylcholine?

During excitation–contraction coupling, acetylcholine evokes an action potential at the neuromuscular endplate. This action potential is propagated to the transverse tubule, causing displacement of the charge at the dihydropyridine receptor. A conformational change at the voltage-gated dihydropyridine receptor is directly transmitted to the ryanodine receptor subtype 1 (RYR1) at the sarcoplasmic reticulum, which responds by opening. RYR1, a large ion channel, facilitates release of calcium from the sarcoplasmic reticulum into the cytosol, leading to muscle contraction by initiating cross-linking of myofilaments. Active reuptake of calcium into the sarcoplasmic reticulum via an adenosine triphosphate-dependent calcium pump terminates the muscle contraction.23

Is halothane used in anesthesia?

Recent developments in anesthesiology seem to have led to a decrease in the risk of severe MH crisis over the last few years. Halothane, a potent MH-triggering agent, is no longer used in western countries.19Compared with halothane, the onset of MH is delayed with the volatile anesthetics currently in use,20,21and is more likely to be abortive MH with attenuated symptoms. Further, the recommended indications for succinylcholine, another possible triggering agent, have been gradually restricted by international anesthesia societies.18,22

Is MH a race?

MH occurs worldwide in all races .7Children and young adults are mostly affected, with a significant male preponderance.7,13,14According to a prevalence study in New York State between 2001 and 2005, the estimated prevalence of MH was 2.5–4.5 times higher in males than in females.15Since many MHS individuals experience no symptoms in daily life, the true incidence of MH remains unknown. The predicted genetic prevalence is reported to be one in 2,000, while the incidence of clinical MH episodes varies regionally from one in 5,000 to one in 100,000.7,16,17In contrast with fulminant episodes, abortive courses might occur more frequently, but are difficult to diagnose due to their mild symptoms.18

What is the MHAUS?

If you plan to travel outside the United States, you can contact the Malignant Hyperthermia Association of the United States (MHAUS). MHAUS will help to determine whether doctors at your travel destination are aware of malignant hyperthermia and equipped to treat it. This is a sensible precaution because it is a rare disease.

What blood test shows malignant hyperthermia?

Blood tests that show changes in the body chemistry hint at malignant hyperthermia. These include high levels of the muscle enzyme CPK ( creatine phosphokinase) and electrolyte changes. Blood tests that show signs of kidney failure also can provide clues. If malignant hyperthermia is not recognized and treated quickly, the person's heart may stop during surgery.

Can you stop heart surgery with malignant hyperthermia?

If malignant hyperthermia is not recognized and treated quickly, the person's heart may stop during surgery . If you experience most or all of the typical symptoms of malignant hyperthermia, your doctor may diagnose this condition without additional testing.

How long does hyperthermia last?

Dental offices. Surgeons' offices. Intensive care units. Symptoms of malignant hyperthermia usually occur within the first hour after exposure to the trigger medication. However, the symptoms can be delayed for up to 12 hours.

Can hyperthermia occur after surgery?

There is a dramatic and dangerous increase in body temperature (hyperthermia) Malignant hyperthermia usually occurs during or after surgery. But it can occur wherever anesthetic medications are used.

What is malignant hyperthermia?

Malignant hyperthermia is a severe reaction to a dose of anesthetics. The reaction is sometimes fatal. It is caused by a rare, inherited muscle abnormality. Infrequently, extreme exercise or heat stroke can trigger malignant hyperthermia in someone with the muscle abnormality.

Can you use succinylcholine for hyperthermia?

That way, your doctor or dentist can avoid using succinylcholine or high-risk anesthetics. You don't have to avoid surgery altogether. Many safe alternative anesthetics are available. If you know that you are susceptible to malignant hyperthermia, consider wearing a medical alert tag.

When to stop cooling a patient?

Cool the patient if core temperature is >39°C or less if rapidly rising. Stop cooling when the temperature has decreased to <38°C.

What is the best treatment for hyperkalemia?

For refractory hyperkalemia, consider albuterol (or other beta-agonist), kayexelate, dialysis, or ECMO if patient is in cardiac arrest.

What is the middle stage of treatment?

In the middle, or action, stage of treatment, clients need the group's assistance in recognizing that their substance abuse causes many of their problems and blocks them from getting things they want. As clients reluctantly sever their ties with substances, they need help managing their loss and finding healthy substitutes. Often, they need guidance in understanding and managing their emotional lives.

What does a therapist do during the initial stage of treatment?

During the initial stage of treatment, the therapist helps clients acknowledge and understand how substance abuse has dominated and damaged their lives. Drugs or alcohol, in various ways, can provide a substitute for the give-and-take of relationships and a means of surviving without a healthy adjustment to life. As substances are withdrawn or abandoned, clients give up a major source of support without having anything to put in its place (Brown 1985; Straussner 1997).

What is corrective recapitulation?

Corrective recapitulation of the primary family group—groups provide a family-like context in which long-standing unresolved conflicts can be revisited and constructively resolved.

Who was the first person to describe 11 factors that contribute to healing as group therapy unfolds?

In 1975, Irvin Yalom elaborated on earlier work and distinguished 11 therapeutic factors that contribute to healing as group therapy unfolds:

Why are adjustments in treatment needed?

Second, adjustments in treatment are needed because progress through the stages of recovery is not timebound. There is no way to calculate how long any individual should require to resolve the issues that arise at any stage of recovery. The result is that different group members may achieve and be at different stages of recovery at the same time in the lifecycle of the group. The group leader, therefore, should use interventions that take the group as a whole into account.

What are some examples of emotional issues in early treatment?

For example, in early treatment, clients can be emotionally fragile, ambivalent about relinquishing chemicals, and resistant to treatment. Thus, treatment strategies focus on immediate concerns: achieving abstinence, preventing relapse, and managing cravings. Also, to establish a stable working group, a relatively active leader emphasizes therapeutic factors like hope, group cohesion, and universality. Emotionally charged factors, such as catharsis and reenactment of family of origin issues, are deferred until later in treatment.
