Objective:
To compare the influence of thoracic epidural analgesia (TEA) with intravenous patient-controlled analgesia with morphine (PCA) on the early postoperative respiratory function after lobectomy.
Study Design:
Prospective and comparative observational study.
Patients And Methods:
Fourty-four patients scheduled for lobectomy (n=22 per group) were studied on the evolution of the postoperative respiratory function assessed by the forced vital capacity (FVC) and the forced expired volume (FEV(1)) during the first two postoperative days and the analysis of noctural arterial desaturation during the three first postoperative nights.
Results:
The use of TEA resulted in fewer decrease both in FEV(1) (1.01+/-0.34 versus 1.31+/-0.51 l/s for Day 1, P=0.03; 1.13+/-0.37 versus 1.53+/-0.59 l/s for Day 2, P=0.01) and in FVC (1.23 [1.05-1.51] versus 1.57 [1.38-2.53] l for day 1, P=0.008; 1.33+/-0.43 versus 2.24+/-0.87 l for day 2, P<0.001). Moreover, the duration of arterial desaturation<90% were longer in the PCA group during the first (8.6 [0.8-28.2] versus 1.3 [0-2.6] min, P=0.02) and the second postoperative night (13.5 [3.5-54] versus 0.4 [0-2.6] min, P=0.025).
Conclusion:
The results of this study suggest that the use of TEA is associated with a better preservation of respiratory function assessed by spirometric data and noctural arterial desaturation recording after thoracic surgery for lobectomy.
