A patient with ruptured spleen is taken for laparotomy. His blood pressure is 80/50 and heart rate is 125/min. Induction agent of choice for this patient is :
-
Sodium Thiopentone
-
Fentanyl
-
Ketamine
-
Halothane
Explanation:
Ketamine increases all pressures (blood pressure, intracranial tension, intraocular pressure) in the body. It is therefore intravenous anaesthetic of choice for shock (increases blood pressure).
