1, the lack of communication with the patient before surgery anesthesia, failed to comfort the patient, eliminate their nervousness, so that the patient informed cooperation; 2, signature is not timely or wait for the patient sent to the door of the operating room and then sign directly;, pre-anesthesia visits do not look at the results of the auxiliary examination. 3, do not like to communicate with the patient, encounter more “annoying” patients simply use sedatives. 4. The patient with a full stomach is not treated with anesthesia hastily. 5. Leaving the workstation without authorization to smoke, drink or chat during the operation, especially in the anesthesia of intrathecal or nerve block. 6.Not checking the anesthesia machine and anesthesia drugs before surgery, and then get busy during the surgery. Rescue equipment must be within reach! 7, the patient into the room after the corresponding cardiac monitoring is not done in a timely manner, not timely detection of the patient’s hidden problems. 8.Injecting anesthetics without opening monitoring and intravenous access. 9.Dispensing drugs without writing labels. 10.The two filters in the epidural puncture kit seem to always be superfluous; 11.Ephedrine, atropine is not routinely pumped; 12.Patients with other concomitant diseases are not prepared for acute attacks of the need for medicines, 13.Switching off the alarm tone of the monitoring during the operation, the operation did not routinely monitor the electrocardiogram, oximetry, blood pressure, etc.; 14.Patterned through the neck of the ampoule did not use iodine povine to wipe a disinfected circle and then break 15.The spinal anesthesia when the The scope of disinfection is not enough, and sometimes even the hole towel is not used. 16. Not washing hands and then wearing gloves before intralesional anesthesia. 17. After drawing medicine, the patient is not treated in accordance with aseptic operation; the patient is not cleaned up in time after the anesthesia; the used syringes are thrown away indiscriminately when they are finished; and the unused ones are not put in the medicine tray and are thrown away indiscriminately. 18. Positioning is not exact first penetration, and then slowly find 19. Turning the epidural puncture needle in the epidural cavity. 20, Not lying flat first injection test volume. 21.Negative pressure test with air instead of saline; 22.Rushed by the surgeon does not comply with the principles, in order to pursue rapid, without the test volume or test volume less than 5min after the large dose of drug administration. 23, Intravertebral anesthesia or nerve block anesthesia with a particularly sharp needle to measure the plane. 24.Sending the patient back to the ward without measuring the plane after the completion of the operation. 25.Sometimes not paying attention to the plane after moving the position, and not checking the tracheal tube. 26.Not giving oxygen to the patient when epidural anesthesia is in progress. 27.Not returning to the room before injecting the drug. 27. There is no habit of pumping back before injecting drugs. In some places, 5ml of lidocaine is given to the patient before reaching the epidural cavity, and then the tube is placed, and the remaining 10ml is given in stages after supine. 28.PCEA epidural catheter was not firmly fixed. 29.Lumbar anesthesia, just after pushing the drug, let the surgeon set the position. 30.When the epidural puncture was intuitively incompetent, the catheter was withdrawn directly instead of withdrawing the puncture needle and catheter at the same time. 31, anesthesia does not pay attention to the process of surgery, to learn to do anesthesia standing. 32.When general anesthesia + epidural, the epidural is induced after giving the full amount. 33, general anesthesia intubation before induction, not at all with the patient about the tracheal tube; 34, the use of general anesthesia bag intubation process, many doctors are the inside of the sterile tracheal tube to the right side of the patient’s head (anesthesia doctors themselves by hand), did not pay good attention to the asepsis. 35, general anesthesia at the end of surgery to send the patient back to the ward without taking the respiratory bag. 36, now the frequency of using the tee is very high, after using the tee often do not use the “cap” “cover” well. Linking the three-way should be first punch and then connected to the drug, pay attention to whether there is no residual gas, do not think that the air less into a little bit of nothing. 37, for obese patients, there is no adequate preparation for difficult airway treatment, hastily use long-acting muscle relaxants to induce intubation. 38,, elective general anesthesia patients do not measure weight. 39, general anesthesia operation are not with sterilized gloves. 40, intubation is not prepared before the suction tube, suction, obese patients are not prepared oropharyngeal airway. 41, general anesthesia before extubation of sputum, many doctors are now in the mouth sucked a few times, and then put into the tracheal tube (should be first suction tube, and then suction the oral cavity), in principle, should be replaced with a sterile one. And much of the suctioning is done with the suction tube pumped up and down and back and forth, not rotationally. Entry should be made by folding the tube, and there should be no negative pressure, which will suck out the tube as well as the stored residual oxygen in the lungs affecting oxygen saturation and thus ventilation. Therefore, attention should be paid to the correct method of sputum aspiration. 42. In order to wake up the patient “in time”, stopping medication too early leads to intraoperative knowledge. 43. The patient’s hand was found to be excessively abducted during the operation, and no intervention was made. 44. When double nasal catheters are used for oxygen administration, it is generally preferred to insert the nasal catheter into the nasal vestibule, but in fact, as long as the opening of the nasal oxygen tube is placed in front of the nasal vestibule, it will be fine. 45.The scope of disinfection is not enough for cervical plexus, brachial plexus, and deep vein puncture. 46.Tracheal tube, dental cushion, and suction tube are repeatedly used without strict disinfection, and the laryngoscope is not disinfected before use. 47, The threaded tube of anesthesia machine is not changed for each patient, and it is often changed for many patients. 48, The right and left suction tubes are not separated during single-lung ventilation (they must be separated). 49. Breathing circuits are not sterilized and are used repeatedly. 50, Hepatitis B-positive patients or unknown hepatitis B or HIV carriers without special treatment. 51, after general anesthesia extubation, the patient has not yet left the operating room, but still in the monitoring of the circuit will be allowed to remove the suction device. 52, the end of the operation of the monitor lead is not separate collection, and even dragged on the ground, not waiting for the patient out of the operating room will be removed from the monitoring. 53, postoperative visit, there are complications can not be dealt with in a timely manner; visit column first written on the anesthesia-free complications. 54. They do not change their gowns when they go out of the operating room.
