Cardiovascular events such as increased or decreased blood pressure, rapid heart rate, or other cardiac dysrhythmias are also common during emergence from general anaesthesia, as are respiratory symptoms such as dyspnoea. Responding and following verbal command, is a criterion commonly utilized to assess the patient's readiness for tracheal ...
Close monitoring by the anesthesia provider will sometimes be provided, to help keep the patient comfortable during a medical procedure, along with other drugs to help relax the body. It can also help control breathing, blood pressure, blood flow, and heart rate and rhythm, when needed. [1] There are four levels of sedation by anesthesia.
The purpose of anesthesia can be distilled down to three basic goals or endpoints: [2]: 236 hypnosis (a temporary loss of consciousness and with it a loss of memory.In a pharmacological context, the word hypnosis usually has this technical meaning, in contrast to its more familiar lay or psychological meaning of an altered state of consciousness not necessarily caused by drugs—see hypnosis).
It is commonly used in major abdominal surgeries, such as bowel resections, liver surgery, and gastric bypass, where deep anesthesia and muscle relaxation are required. In cardiac surgery, balanced anesthesia facilitates precise control of heart rate and blood pressure, which is critical during these complex procedures.
This drop in blood pressure may activate a reflexive increase in heart rate, due to a baroreceptor-mediated feedback mechanism. Some anesthetics, however, disrupt this reflex. [3] [4] Patients under general anesthesia are at greater risk of developing hypothermia, as the aforementioned vasodilation increases the heat lost via peripheral blood flow.
In addition to use by cardiologists in outpatient and inpatient settings, TEE can be performed by a cardiac anesthesiologist to evaluate, diagnose, and treat patients in the perioperative period. Most commonly used during open heart procedures, if the patient's status warrants it, TEE can be used in the setting of any operation.

It deals with the anesthesia aspects of care related to surgical cases such as open heart surgery, lung surgery, and other operations of the human chest. These aspects include perioperative care with expert manipulation of patient cardiopulmonary physiology through precise and advanced application of pharmacology , resuscitative techniques ...
