Although most jurisdictions have extended the “locality rule” to encompass Medical Malpractice a national standard of care, medical malpractice (also see Chapter 54) cases are governed by the laws of the jurisdiction A healthy 45-year-old man has a cardiac arrest in which the event took place and these may dif- during an elective laparoscopic inguinal hernia fer from state to state.

The law recognizes that there are diﬀer- changes in mental status that preclude his return ences of opinion and varying schools of thought to work. It is usually the plaintiﬀ who bears the burden What four elements must be proved by of proving that the injury would not have occurred the plaintiﬀ (patient) to establish negligence “but for” the negligence of the physician, or that on the part of the defendant (physician or the physician’s action was a “substantial factor” in hospital)? Duty: Once a physician establishes a profes- of res ipsa loquitur (“the thing speaks for itself”), sional relationship with a patient, the physician which permits a ﬁnding of negligence based owes that patient certain obligations, such as solely on the evidence. Breach of Duty: If these obligations are not ful- radiograph after a thoracotomy, the doctrine of ﬁlled, the physician has breached his duties to res ipsa loquitur would apply. The injury may because the plaintiﬀ would have to establish that result in general damages (eg, pain and suﬀer- cardiac arrest could not occur in the absence of ing) or special damages (eg, loss of income). Causation: The plaintiﬀ must demonstrate that been due to something outside the control of the the breach of duty was causally related to the anesthesiologist.
