Complications of anesthesia
Complications of anesthesia include vomiting, respiratory arrest, collapse, thrombophlebitis.
Vomiting is prevented by a pre-narcotic fasting diet. If vomiting occurs, the head is given a lower position to relieve vomiting and the oral cavity is cleaned with tampons.
Respiratory arrest can be reflexive and due to intoxication in case of drug overdose. When breathing stops, anesthesia is stopped, released from fixation belts, lobelia, caffeine are injected subcutaneously or intravenously and artificial respiration is immediately started. For this, the tongue is pulled from the oral cavity, the chest limbs are taken forward, and then brought to the chest, thereby expanding and squeezing it rhythmically. In addition, you can take one limb aside, then press it against the body and press on the side of the chest wall with your palm. Sometimes a rhythmic pat on the chest wall is effective.
If the abdominal cavity was opened during surgery, a hand is inserted into it and the diaphragm is massaged, slightly pressing it and patting it with fingers.
Collapse often occurs in small animals and horses. With collapse, there is a sudden weakening of cardiac activity, cyanosis, dilated pupils, a weak pulse, and the cessation of bleeding from cut vessels. In this case, anesthesia is immediately stopped, caffeine and camphor or intravenous adrenaline are injected subcutaneously. Light rhythmic strokes of the palm of the chest massage the heart. The last measure in the event of collapse is an intracardial injection of adrenaline in the first 5 minutes after the cardiac arrest has stopped.
Thrombophlebitis occurs with errors in the technique of intravenous administration. This is prevented by the immediate infiltration of a 0.25-0.5% solution of novocaine in the tissue where the chloral hydrate solution has got.

- Anesthesia Types and stages of anesthesia
General anesthesia, or anesthesia, is a state of the body that is characterized by a temporary shutdown of a person’s consciousness, pain sensitivity and reflexes, as well as a relaxation of skeletal muscle muscles caused by the action of narcotic analgesics on the central nervous system.

- Complications of maintaining anesthesia
hypoxia and hypercapnia - develops when the airway is blocked by clots of mucus, blood, a foreign body, a violation of the tightness of the respiratory system, a decrease in oxygen concentration, the patient is forced to stand on the operating table, and an endotracheal tube falls out. - Hemodynamic disorders: hypotension, arrhythmia, etc., associated not only with anesthesia, but also with trauma

Acute and chronic inflammation of the nasal cavity and its adnexal lumps can cause a series of ocular and intracranial complications, which often lead to loss of vision, and sometimes end in the death of the patient.
