Question

Which opioid increases cerebral blood flow (CBF) and intracranial pressure (ICP), and what are the implications for neuroanesthesia?

Option 1: Morphine
Option 2: Fentanyl
Option 3: Remifentanil
Option 4: Meperidine

Answer 1

Meperidine is the opioid that increases cerebral blood flow (CBF) and intracranial pressure (ICP), which is important for anesthesiologists to consider in neuroanesthesia to prevent complications in patients with brain injuries or tumors.

Step-by-step explanation:

The opioid that increases cerebral blood flow (CBF) and intracranial pressure (ICP) is meperidine. Meperidine is known to increase the production of carbon dioxide, which can lead to vasodilation and consequently an increase in CBF and ICP. This is significant in the field of neuroanesthesia as increased ICP can be detrimental to patients with brain injuries or tumors due to the limited space within the skull. Anesthesiologists must carefully manage analgesia and anesthesia in neurosurgical patients to avoid exacerbating increased ICP and to optimize patient outcomes.
