Abstract:
BACKGROUND:Pain following thoracotomy can persist for years with an undetermined impact on quality of life. Factors hypothesized to modulate this painful experience include analgesic regimen, gender, and type of incision.
METHODS:A total of 157 generally healthy patients of both genders scheduled for segmentectomy, lobectomy, or bilobectomy through a posterolateral or muscle-sparing incision were randomly assigned to receive thoracic epidural analgesia initiated prior to incision or at the time of rib approximation. Pain and activity scores were obtained 4, 8, 12, 24, 36, and 48 weeks after surgery.
RESULTS:Overall, there were no differences in pain scores between the control and intervention groups during hospitalization (P >or= 0.165) or after discharge (P>or= 0.098). The number of patients reporting pain 1 yr following surgery (18 of 85; 21.2%) was not significantly different (P = 0.122) from the number reporting preoperative pain (15 of 120; 12.5%). During hospitalization, women reported greater pain than men (worst pain, P= 0.007; average pain, P= 0.016). Women experienced fewer supraventricular tachydysrhythmias (P = 0.013) and were thus discharged earlier (P = 0.002). After discharge women continued to report greater discomfort than men (P journal_name journal_title authors doi subject pub_date pages issue eissn issn pii journal_volume pub_type
