To classify the types of pain, Verbal Rating Scale (VRS) scores were used to collect the pain symptoms of patients with 6 time periods of wound, throat, infusion, other and non-intervention for 6 days, and analyze the characteristics and correlated factors of moderate and severe pain.Results:Eighty-seven of the 239 patients complained of moderate or severe pain. The distribution of patients age and education level had statistical differences in the presence or absence of moderate to severe pain (n P<0.05) . The cases of sore throat and frequency occurred most frequently among all types of pain.n Conclusions:Although patient-controlled analgesia is given to patients after flap repairment, more than one-third of patients still complained of moderate and severe pain. Different types of pain have different characteristics, and throat pain occurred more frequently. Moderate pain was more common in male patients, while severe pain has a much higher proportion in female patients.
