A severely ill patient was maintained on an infusional anaesthetic agent. On the 2ndday he started detiorating. The probable culprit may be –
**Core Concept**
The question revolves around the concept of infusion anaesthetics and their potential side effects, particularly in critically ill patients. Infusion anaesthetics, such as propofol, are commonly used for sedation and anaesthesia due to their rapid onset and short duration of action.
**Why the Correct Answer is Right**
The probable culprit in this scenario is the infusion anaesthetic agent causing propofol infusion syndrome (PRIS). PRIS is a rare but life-threatening condition characterized by metabolic acidosis, rhabdomyolysis, and cardiac arrest. It occurs due to the accumulation of propofol's metabolites, which can lead to mitochondrial dysfunction and energy depletion. Propofol's lipid emulsion can also cause microvascular fat embolism syndrome, which may contribute to the patient's deterioration.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not directly relate to the potential side effects of infusion anaesthetics. While other medications can cause similar side effects, they are not the primary concern in this scenario.
**Option B:** This option is also incorrect as it does not specifically address the potential issues with infusion anaesthetics. Other factors, such as infection or sepsis, may contribute to a patient's deterioration, but they are not directly related to the anaesthetic agent.
**Option C:** This option may seem plausible, but it is not the most likely cause of the patient's deterioration. While hypotension can be a side effect of infusion anaesthetics, it is not typically associated with the severe complications seen in PRIS.
**Option D:** This option is incorrect as it does not accurately describe the potential side effects of infusion anaesthetics. While cardiac arrest can occur in PRIS, it is not the primary concern in this scenario.
**Clinical Pearl / High-Yield Fact**
A key aspect of managing critically ill patients on infusion anaesthetics is regular monitoring of their vital signs and laboratory values. Early recognition of PRIS symptoms, such as metabolic acidosis and rhabdomyolysis, can help prevent catastrophic outcomes.
**Correct Answer:** C. Propofol infusion syndrome.
