The probability of medical disputes in pediatric ward is much higher than other offices. Taking the pediatric outpatient room in Maternal and Child Health Hospital of Foshan City as a case, we found that when it comes to the problem of the relationship, there is a sharp difference between the doctor and patient. There are two sort of asymmetry. One is that doctors belieue it's the imbalance in access to medical information that contributes to the conflicts between them,however patients see that the emotional needs in addition to the medical information caused the conflicts between them. The other is that doctors see the physician-patient communication as a mutual interaction of two parties; On the contrary patients see the communication as the doctors’ behavior. It is suggested the doctor has to control the dynamic in the relationship with a patient, and they also have to attach greater importance to the first part of “the ideal sequence organization”, and shift the focus from providing medical information to placating social emotions. In the treatment process, once the patient has the mood or behavior of “medical trouble”, doctor has to find the real need of him or her.
