Case 1-1

LOCATION: Inpatient, Hospital

PATIENT: Mike Bahs

ATTENDING PHYSICIAN: Loren White, MD CONSULTANT: Timothy Pleasant, MD

REASON FOR CONSULTATION: Rule out neck injury.

HISTORY: This patient is a 17-year-old male who was involved in a motor vehicle accident last night. He remembers driving down the road and the next thing he remembers was trying to reach for his cell phone at a stop sign after the accident. He does not remember any of the details. The car apparently went off the road and hit a tree. The patient is amnesiac for the event but does not believe he lost consciousness. His vehicle was apparently traveling 35-40 miles an hour. There was no report that he was ejected from the vehicle.

PAST MEDICAL HISTORY: He had childhood asthma.

MEDICATIONS: None.

ALLERGIES: None.

FAMILY HISTORY: Noncontributory to the present problem. SOCIAL HISTORY: He chews tobacco. Alcohol use is rare.

EXAMINATION: Vital signs show he is afebrile. Pulse 64. Blood pressure 110/50. Neurologic: He is awake, alert, and fully oriented. His cranial nerves are grossly intact. HEENT: His extraocular movements are full. His eyes are conjugate. His pupils are equal. His facial strength is intact. On motor examination, he has grossly normal motor strength bilaterally in the upper and lower extremities. His reflexes are normal and symmetric at the biceps, triceps, and brachioradialis. The ankle jerks and the knee jerks are normal and symmetric. Gait is not tested. Sensory examination is grossly intact to light touch. Spine examination: The patient’s cervical collar was removed. He has no tenderness to palpation of the cervical spine whatsoever.

The x-rays of the cervical spine, as well as the CT scan of the cervical spine, were reviewed. No fractures or subluxations are noted. CT scan of the head was reviewed, and it is negative for any intracranial pathology.

IMPRESSION/PLAN: In summary, we have a 17-year-old male involved in a motor vehicle accident. He has a mild concussive head injury, as evidenced by his amnesia, and I believe he did lose consciousness for a brief period; however, the exact amount of time for his loss of consciousness is unknown. There is no evidence of any cervical spine injury. The patient is neurologically normal. He does not need to wear a cervical collar. I explained to him and his

mother, Gloria, that if the patient develops any weakness, numbness, or tingling in the arms or legs, trouble with his balance, sleepiness, vomiting, weakness of one side of the body, or any other symptoms, they should call their physician immediately.

I want to thank Dr. White for asking me to see this patient.

Write a short conclusion about this article

Lucid is among a wave of electric-vehicle startups getting closer to releasing their first models, looking to challenge traditional auto makers like General Motors Co. and Volkswagen AG that are investing billions in the technology and Tesla Inc., a company that continues to dominate the scene for high-price battery-powered cars.

Backed by Saudi Arabia’s sovereign-wealth fund, Lucid is taking aim at the luxury end of the market with the Air, hoping to not only carve into Tesla’s market share but also attract more conventional sedan buyers from BMW AG, Daimler AG ’s Mercedes-Benz and other premium brands, its executives say.

Chief Executive Peter Rawlinson said that based on the company’s own testing, the priciest Air is expected to deliver a battery range of more than 500 miles, a distance that would beat current competitors, including the longest-range version of the Tesla Model S. The Environmental Protection Agency hasn’t certified that range yet.

The first, fully loaded four-door Air will start around $160,000 after factoring in federal subsidies. The company will release cheaper versions throughout the year with a roughly $70,000 version coming in 2022.

Like Tesla, Lucid plans to sell its models directly to customers, bypassing the traditional dealership network, and expects to open a new retail and service location in Beverly Hills, Calif. later this month.

Mr. Rawlinson said that while there have been pricier electric models released in recent years, Tesla still holds a commanding lead and there is room for more competition.

“We see just how far ahead Tesla is,” he said. “They are five years or more ahead of everyone else, and the shock is the gap is not being closed. The gap is growing as we speak.”

The Lucid Air makes its debut as tougher auto-emissions regulations are pushing car makers to add more battery-powered models to their lineups, and investors, excited by Tesla’s recent stock market success, are pouring money into the technology. Tesla’s market value has nearly quadrupled this year, making it the world’s most valuable auto maker ahead of GM, Toyota Motor Corp. and Volkswagen.

The Air also arrives as the marketplace for electric cars is expected to become increasingly crowded in the coming years, with dozens of new plug-in models planned, including many aimed at wealthier buyers. Investors are excited by the startups, several of which went public this year and have seen their valuations soar.

Some upstarts, like Rivian Automotive LLC and Nikola Corp. are choosing to align with traditional auto makers that have deeper pockets and the car-manufacturing expertise to help them realize their plans. This week, GM said it would take an 11% stake in Nikola, a maker of electric and hydrogen fuel trucks, in exchange for helping it to engineer and build its first model.
