Autonomy varies and some patients find it overwhelming especially the minors when faced with emergency situations. Issues arise in emergency room situations where there may not be time to consider the principle of patient autonomy. Various ethical challenges are faced in these situations when time is critical, and patient consciousness may be limited. However, in such settings where informed consent may be compromised, the working physician evaluates each individual case to make the most professional and ethically sound decision. For example, it is believed that neurosurgeons in such situations, should generally do everything they can to respect patient autonomy. In the situation in which a patient is unable to make an autonomous decision, the neurosurgeon should discuss with the surrogate decision maker in order to aid in the decision making process. Performing surgery on a patient without informed consent is in general thought to only be ethically justified when the neurosurgeon and his/her team render the patient to not have the capacity to make autonomous decisions. If the patient is capable of making an autonomous decision, these situations are generally less ethically strenuous as the decision is typically respected.
