Abstract
Objectives
To assess the effect of thoracic paravertebral block (PVB) on pain management
and preservation of pulmonary function compared with intravenous,
patient-controlled analgesia (IVPCA) in patients with multiple rib fractures
(MRFs).
Methods
Ninety patients with unilateral MRFs were included in this prospective study
and randomly assigned to the TPVB or IVPCA group. The visual analogue scale
(VAS) pain score, blood gas analysis, and bedside spirometry were measured
and recorded at different time points after analgesia.
Results
TPVB and IVPCA provided good pain relief. VAS scores were significantly lower
in the TPVB group than in the IVPCA group at rest and during coughing
(P < 0.05). Patients in the TPVB group had a higher
PaO2 and PaO2/FiO2 and lower
P(A–a)O2 compared with the IVPCA group
(P < 0.05). Moreover, patients in the TPVB group
showed higher FVC, FEV1/FVC, and PEFR, and fewer complications than did the
IVPCA group (P < 0.05).
Conclusion
TPVB is superior to IVPCA in pain relief and preservation of pulmonary
function in patients with MRFs.
