pMDT in Thoracic Surgery--------For the Baseline Investigation and Technical Preparation Stage
Condition: Pain, Postoperative
MeSH terms: Pain, Postoperative
Study type: Observational

Summary: 
      The risk of acute and chronic pain after thoracic surgery is high. The multi-disciplinary
      postoperative pain management strategy is the best way to control postoperative pain in
      thoracic surgery. Through nearly one year of experience in implementation of the pMDT in the
      thoracic surgery department of Peking University People's Hospital, the investigators have
      summarized the experience in multidisciplinary pain management and promoted this study in
      multi-centers across the country, hoping that this study can improve the current situation of
      acute pain management in patients after thoracic surgery, and at the same time, the
      deficiencies of this clinical protocol can be found out and improved.
    

Detailed description: 
      The postoperative acute pain refers to the acute pain (usually lasting less than 7 days) that
      occurs immediately after surgery, and its nature is traumatic pain. It may develop into a
      chronic pain, such as a neuropathic pain or a mixed pain, if it is not fully controlled at
      the initial state. It will seriously impact the physiology and psychology of a patient.
      According to the study, the postoperative acute pain is one of the risks for postoperative
      complications, and it may result in the death of a patient. However, the alleviation of a
      postoperative acute pain can shorten the duration of stay in hospital, and reduce the overall
      cost for treatment of a patient.

Intervention name(s): pMDT(Baseline Investigation)
Intervention type(s): Other
Intervention description(s): The pMDT(Baseline Investigation) takes multi-model analgesia as the main technical means. Multimodal perioperative analgesia refers to the combination of analgesics, adjuvant drugs and analgesic techniques with different effects throughout the perioperative period to achieve the best curative effect of reducing postoperative acute and chronic pain.
Observational model: Case-Only
