<prompt> A patient was operated for right upper lobe resection. He was shifted to post awakening recovery after completion of surgery with vitals- BP 10070 mm of Hg, HR - 94bpm, SPO2 100. After 2 hrs when he was assessed ,his vitals was BP 7050 mm of Hg. HR-126 bpm ,SPO2 92 and surgical drain was filled with blood. Immediate re-exploration was planned. IV anaesthetic agent of choice -KetaminePropofolThiopentoneEtomidate  <response>: Acute shock IV anesthetic agent of choice ketamine. Intravenous induction agent of choice in hypotension isketamine etomidate. Ketamine helps to maintain aerial pressure, hea rate, and cardiac output due to central stimulation of the sympathetic nervous system and inhibition of the reuptake of norepinephrine Propofol if given , lead to worsening of shock due to the profound hypotensive action of propofol because of its vasodilatory and negative inotropic effects.
