Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
Depending on the extent of ischemia, symptoms of arterial occlusion range from simple soreness and pain that can be relieved with rest, [3] to a lack of sensation or paralysis that could require amputation. [3] Arterial occlusion can be classified into three types based on etiology: embolism, thrombosis, and atherosclerosis.
Treatment options for full-term and preterm babies who develop thromboembolism include expectant management (with careful observation), nitroglycerin ointment, pharmacological therapy (thrombolytics and/or anticoagulants), and surgery. [19] The evidence supporting these treatment approaches is weak.
Intraoperative signs that may indicate patient awareness include: [9] hypertension; tachycardia; patient movement; tachypnea [10] intravenous anesthesia line infiltrated or occluded [10] Patients under anesthesia are paralyzed if a neuromuscular blockade drug, a type of muscle relaxant, has been given as part of general anesthesia. When ...
The symptoms are similar to those caused by some other diving injuries and differential diagnosis can be complicated and uncertain if several possible causes for the symptoms coexist. First aid is breathing the highest practicable concentration of normobaric oxygen. Definitive treatment is recompression with hyperbaric oxygen therapy. Anti ...
Symptoms may begin quickly or slowly depending on the size of the embolus and how much it blocks the blood flow. [2] Symptoms of embolisation in an organ vary with the organ involved but commonly include: Pain in the involved body part [2] Temporarily [2] decreased organ function; Later symptoms are closely related to infarction of the affected ...
Treatment for thrombotic storm may include lifelong anticoagulation therapy and/or thrombolytic therapy, plasmapheresis, and corticosteroids. Studies have shown that when anticoagulant therapy is withheld, recurrence of thrombosis usually follows. International normalized ratio is closely monitored in the course of treatment.
Intravenous anesthetic agents are titrated at safe doses to maintain stage III surgical anesthesia (unconsciousness, amnesia, immobility, and absence of response to noxious stimulation). [10] The use of TIVA is advantageous in cases where volatile anesthesia is of high risk or is impossible, such as cases involving morbidly obese patients.
