A patient presented with blunt trauma to the abdomen to the emergency depament. His hea rate is 150/min and his BP 80/50 mm Hg.He is scheduled to undergo an emergency laparotomy. Which of the following is anaesthetic agent of choice?
The cardiovascular stimulatory effects make ketamine a desirable drug for the induction of anesthesia in unstable cardiovascular patients suffering from hypovolemia, hemorrhagic shock, or cardiovascular depression in sepsis. Ketamine bronchodilation and profound analgesia allowing the use of high oxygen concentrations make ketamine an excellent choice for induction of anesthesia in patients with reactive airway disease. Patients who have sustained trauma with extensive blood loss are typical candidates for rapid-sequence anesthesia induction with ketamine. Patients with septic shock also may benefit from ketamine. The intrinsic myocardial depressant effect of ketamine may manifest in this situation if trauma or sepsis has caused depletion of catecholamine stores before the patient's arrival in the operating room. The use of ketamine in these patients does not obte the need for appropriate preoperative preparation, including restoration of intravascular blood volume.
