Resuscitation in cardiac arrest following anesthetic accidents

Resuscitation in Cardiac Arrest Following Anesthetic Accidents

Cardiac arrest following an anesthetic accident is a rare, but serious, complication that can lead to significant or fatal outcomes. This report explores the anesthetic and resuscitation techniques used to reverse cardiac arrest following anesthetic-related events.

Cardiac arrest due to anesthetic-related complications is an infrequent, but serious adverse event. Anesthetists must be aware of the clinical presentation in order to adequately diagnose and manage potential complications. The American Society of Anesthesiology (ASA) defines anesthetic-related cardiac arrest as an event resulting from "a subtle yet dangerous delay in the recognition or response to a hazardous situation."

Causes of Cardiac Arrest Following Anesthesia

The causes of cardiac arrest following anesthesia include:

  • Hypoventilation
  • Drug overdose
  • Increase in intracranial pressure
  • Hypothermia
  • Hypo- and hyperkalemia
  • Tension pneumothorax
  • Surgical and anesthesia-related errors

Treatment of Cardiac Arrest Following Anesthesia

The treatment of cardiac arrest following anesthesia begins with basic life support such as chest compressions, defibrillation, and positive pressure ventilation. However, due to the potential complexity of causes of cardiac arrest following anesthetic accidents, pharmacologic interventions may be necessary. There are several drugs that may be beneficial in the resuscitation of an anesthetic patient, including epinephrine, amiodarone, and calcium.

Epinephrine is a sympathomimetic agent that increases cardiac output and coronary perfusion pressure. It is used to assist in the resuscitation of patients with initial rhythm disturbances and those who remain in a shock state despite adequate fluid and inotropic therapy. Amiodarone is a class III antiarrhythmic drug that is used to manage ventricular and supraventricular tachyarrhythmias. Calcium is a positive inotropic agent and may be used to correct and prevent dysrhythmias.

Conclusion

Cardiac arrest following anesthetic accidents is a rare, but potentially fatal event. Early recognition is essential for successful patient outcomes. Anesthetists must be aware of the causes and treatments of cardiac arrest following anesthesia and must be prepared to implement appropriate resuscitation techniques in the event of an anesthetic-related complication.

Read the following passage carefully and answer the questions given below.The Italian banking system became the model for those North European nations that would achieve the greatest commercial success in the coming centuries, notably the Dutch, the English, and the Swedes. It was in Amsterdam, London and Stockholm that the next decisive wave of financial or innovation occurred, as the forerunners of modern central banks made their first appearance. The seventeenth century saw the foundation of three distinctly novel institutions that, in their differen in ways, were intended to serve a public as well as a private financial function. The Amsterdam Exchange Bank, i.e. the Wisselbank, was set up in 1609 to resolve the practical problems created for merchants by the circulation of multiple currencies in the United Provinces, where there were no fewer than fourteen different mints and copious quantities of foreign coins. By allowing merchants to set up accounts denominated in a standardized currency, the Exchange Bank pioneered the system of cheques and direct debits or transfers that we take for granted today. This allowed more and more commercial transactions to take place without the need for the sums involved to materialize in actual coins. Financial historians disagree as to how far the growth of banking after the seventeenth century can be credited with the acceleration of economic growth that began in Britain in the late eighteenth 20 5 century and then spread to Western Europe, North America and Australasia. But banks played a more important role in continental European industrialization than they did in England's.a) Where did the precursors of modern central banks make their first appearance? b) What practical problem was the Wisselbank required to resolve in its initial days?c) How did the Amsterdam Exchange Bank respond to the demand of the age? d) What are the points of disagreement among the financial historians with respect to growth of banking vis-a-vis growth of economy? e) Choose a suitable title for above composition.

Write a precis of the following paragraph and provide a title:The stated intention of most regulators is to maintain stability within the financial services sector, thereby protecting the consumers whom banks serve and the 'real' economy which the industry supports. Every shock to the financial system must result in casualties. Left to itself, natural selection should work fast to eliminate the weakest institution in the market, which typically are gobbled up by the successful. But most crises also usher in new rules and regulations, as legislators and regulators rush to stabilize the financial system and to protect consumers who are also voters. The critical point is that the possibility of extinction cannot and should not be removed by excessively precautionary rules. As Joseph Schumpeter wrote more than seventy years ago, 'This economic system cannot do without the ultima ratio of the complete destruction of those existences which are irretrievably associated with the hopelessly unadapted.' This meant, in his view, nothing less than the disappearance of 'those firms which are unfit to live'. It remains to be seen whether the extraordinary measures taken by Western governments since September 2008 will have the desired effect of preventing complete breakdown of the financial system or whether they will in fact end up impeding the process of financial evolution.
