Ensuring that patients undergo surgery successfully under painless and safe conditions is the basic task of clinical anesthesia, but this is only

Most people consider an anesthesiologist to be a doctor who relieves pain through medication and makes the patient unconscious. But few people realize that in addition to ensuring the comfort of patients, the tasks of today's anesthesiologists in the operating room are more important during surgery and recovery period caused by multiple factors (anaesthesia, surgery, etc., primary disease). Monitoring, diagnosis, and treatment of changes in important vital functions of the patient to ensure the safety of patients during the perioperative period.

Anesthesiologists need extensive knowledge to be competent for this task. They need to have basic and clinical knowledge in pathophysiology, pharmacology, internal medicine, surgery, women and children, and anesthesia. As an anesthesiologist, to relieve the patient's pain, it is necessary to manage the vital vital signs of the patient, including breathing, heart rate, blood pressure, heart, nervous system, liver and kidney function, etc.

Anesthesiologists treat medical problems that occur during the perioperative period (a period of time before and after the operation). The anesthesiologist judges the condition of the patient before surgery, considers the individual differences based on the patient's physical condition, and formulates a treatment plan based on this. During the operation, advanced equipment is used to monitor the patient's life function. Anesthesiologists must rely on a variety of sophisticated and precise instruments to make accurate diagnosis of the condition and maintain the patient's life, some of which are already very fragile.

At the end of the operation, the patient will be taken to the recovery room or intensive care (ICU) ward, and returned to the ward after recovering from anesthesia. Anesthesiologists work in addition to the operating room, as well as intensive care and pain treatment.

What is the job of an anesthesiologist?

Anesthesiologists are also known as physicians in the operating room. Not only are they proficient in various anesthesia techniques to ensure that the patient's surgery is painless and the operation proceeds smoothly, but they also use advanced equipment to monitor the patient's vital functions at any time. The patient's original disease causes problems that threaten the patient's life, so various treatment measures are taken to maintain the stability of the patient's life function and ensure the safety of the patient.

Generally speaking, the clinical anesthesiologist is responsible for: 1. Jointly determining with the patient's doctor whether the patient can withstand surgical anesthesia; 2. Deciding on the type of anesthesia and monitoring measures; 3. Performing anesthesia on the patient; 4. Making every effort to ensure that the entire procedure Patient safety; 5. Safe and stable recovery of patients after surgery; 6. Postoperative pain treatment; 7. Chronic pain treatment.

What is the anesthesiologist doing during the operation? The anesthesiologist works like the pilot of an airplane. Taking off and landing is equivalent to anesthesia induction and recovery. The autopilot used during flight is equivalent to anesthetics, muscle relaxants and mechanical breathing. During the operation, the anesthesiologist must continue to observe the patient, enter the central nervous system through the information obtained through the eyes, ears, and hands, analyze the monitoring data, think about and form some detailed and complex judgment results, and then perform the drug (including Anesthesia, muscle relaxants, fluids, hemostatics, etc.) are adjusted to maintain the physiological function of the patients as smooth as possible, and emergency rescue is performed in emergency situations.

Hand: One finger on the pulse beat is equivalent to several monitors. It can provide pulse rate and presence or absence of arrhythmia. Helps maintain contact between anesthesiologist and patient. The perception of the patient's skin is important: dry and warm skin indicates good clinical condition; cold and moist skin indicates shock during surgery. By compressing or massaging the skin and paying attention to the capillary refilling time, you can know whether the tissue perfusion is proper.

Eyes: The following observations can be made.

(1) Skin: cyanosis or pink indicates improper breathing or other reasons; paleness and sweating indicate bleeding or shock.

(2) Head and Neck: Eye movement indicates shallow anesthesia; dilated pupils (although enlarged with atropine) suggest deep anesthesia, the effects of ganglion blockers, acute hypoxia and / or respiratory failure.

(3) Chest: Chest movement indicates that air enters the lungs. Is bilateral expansion symmetrical? If the patient is breathing spontaneously, changes in breathing rhythm are accompanied by changes in breathing depth. Tracheal traction indicates that the effect of the muscle relaxant has not completely disappeared; retraction of the interthoracic muscles of the lower chest indicates an airway obstruction.

(4) Abdomen: During laparotomy, observe the operation and determine whether the muscle relaxation is appropriate? Is the patient nervous? Is there a lot of bleeding? What is the amount of blood in the suction bottle? How much is the abdominal contamination? (This is related to postoperative shock)

(5) Instrument: Does the rotor tachometer show proper airflow? Is the volume of the graduated cylinder appropriate? Is the vaporizer installed correctly? Is there an anesthetic in the volatilizer? Does the breathing valve need to be adjusted? Is the airbag properly inflated? If you use soda lime, what color is soda lime? Has soda lime failed? Check the device of the ventilator: inflation pressure, inflation rate, and negative pressure. Can the ventilator expand the chest? Is the connection appropriate? Is the airflow rate appropriate? Check the volume and speed of intravenous infusion; if transfusion, check the number of the blood bottle and the number of the patient to make sure the blood is correct for the patient

(6) Physiological monitoring: Measure pulse and blood pressure and record every 5 minutes; if you use a heart monitor, you can also take the reading on the monitor or the value displayed on the pulse monitor. The blood loss during the operation must be recorded throughout the operation.

(7) Did the surgery proceed as planned or changed? What unexpected difficulties did the surgeon have? Is there a lot of blood loss? Is the pressure appropriate if using a tourniquet?

Ear: During the procedure, the anesthesiologists almost unconsciously heard the sound of the exhaled breath from the exhalation valve, even small changes can be heard quickly; the noise and rhythm of the ventilator changed, and Can be detected immediately. The pilot of the aircraft noticed the changes in the tone of the engine and its rhythm with the same skill and speed even when talking. A stethoscope is often used during anesthesia. It is necessary to place a stethoscope in the precardiac area to monitor children's breathing and heart rate. It can also be used to measure and record blood pressure. The nature of spontaneous breathing can provide information, laryngeal spasms suggest shallow anesthesia; stopping breathing after exhalation means shallow anesthesia, and stopping breathing after inspiration means deep anesthesia, accompanied by abdominal muscle relaxation. Heart rate monitors can emit acoustic signals, but they can be disturbed by temperature or other electronic devices, and they can suddenly interrupt a signal if someone trips a wire or lead.

The ear must also be able to withstand noise and irrelevant conversations. These noises can make it impossible to concentrate and cause excitement. The anesthesiologist has the right to ask for silence and even stop the staff from moving. Some surgeons prefer to whistle and never allow whistle when induction of anesthesia in the anesthesia room.

Keeping quiet in the anesthesia room should be the rule, and conversation is strictly forbidden. The patient can even hear a whisper at some stage of anesthesia induction. During surgery, the public allows the surgeon and the anesthesiologist to speak. When the surgeon is performing a delicate operation, the anesthesiologist should be careful not to talk so as not to disturb him. However, during a lengthy surgery, intermittently speaking a few words, or even joking, can make people's spirits slightly relaxed and temporarily relieve the lasting concentration of attention.
