Abstract: Objectives To explore the optimal startup time of patient controlled intravenous analgesia (PCIA) in aged patients after thoracotomy for pulmonary lobectomy.Methods The 67 aged patients after thoracotomy for pulmonary lobectomy from January to December 2008 were randomized divided into two groups:PCIA was startup immediately after waking (instantly group) or after removal tracheal intubation (delayed group).The analgesia efficacy,cardiopulmonary function and side effect were evaluated at the awake time,12,24 and 48 hours after surgery respectively.Result Both of VAS scores at 12 hours after surgery and oxygenation index at 48 hours after surgery had significant difference (P<0.05) between the two groups.The analgesia efficacy was better in the instantly group.There was no significant difference on the duration of mechanical ventilation and side-effect rates between the two groups.No patient suffered from respiratory depression.Conclusion The early use of PCIA in aged patients after thoracotomy for pulmonary lobectomy can gain better pain control and oxygenation effect.
