Hospice care & Palliative medicine specialists focus their practice on pain management, symptom relief and qualify-of-life treatments to relieve the suffering of terminally ill patients. These doctors have specialized expertise in the treatment of patients with serious illnesses, advanced diseases and conditions resulting from catastrophic injury. Though often they work within hospice settings, they prevent and alleviate suffering appropriate at any age and stage of disease and can work alongside practitioners providing curative treatments.
Hospice care & Palliative medicine focuses on depression, pain, fatigue, constipation, nausea, shortness of breath, loss of appetite and difficulty sleeping, among other conditions. They also alleviate psychosocial distress and other stressors that accompany terminal illnesses. They are skilled in guiding families through legal and ethical decision-making in end-of-life care and can address spiritual issues at these times. By coordinating care across settings by improving communication among providers, they improve access to information for families so that they understand the patient's condition and treatment options.

Anesthesiologists are physicians who are trained to administer anesthetics, which are medicines used to block nerve sensation. Anesthesia can be either local to one specific part of a body, like a tooth, or regional to block feeling to a larger portion of the body, such as during an epidural for child birth. It can also be more general to block sensation to the entire body, resulting in unconsciousness.
Anesthesiologists assist in surgery by determining how much anesthesia is necessary and by monitoring the patient's level of responsiveness and vital signs throughout the procedure. The anesthesia specialist will also bring the patient out of anesthesia and then continue to monitor his or her vital signs post-operation.
Besides assisting in surgeries, anesthesiologists may also treat patients suffering from chronic pain.

A pediatrician is a doctor who specializes in the regular care of children, as well as the diagnosis and treatment of illness in children. Young patients are often more complicated to treat because they are still growing and developing.
While pediatricians may sub-specialize in specific therapy areas like oncology, surgery, ophthalmology, and anesthesiology, in general, pediatricians provide services like vaccinations, health exams, and treatment of common ailments and injuries. In addition, pediatricians are trained to handle the complex emotional and behavioral issues faced by children, especially during puberty.
Pediatricians normally see their patients from birth until the age of 18, although some may agree to treat patients into their early 20s, if requested.
