Abstract
The primary objective of postoperative analgesia is to provide subjective comfort and alleviate the suffering of a patient, who is recuperating from surgery. Acute postoperative pain can cause detrimental effects on multiple organ systems and development of chronic pain syndromes after certain surgeries.
An effective regimen of postoperative analgesia not only shortens the time to recovery after surgery, but also helps in avoiding the pulmonary, haemodynamic and metabolic complications of acute post-surgical pain.
Ninety patients undergoing unilateral thoracic surgery were randomly classified into three groups. 30 patients received general analgesia, 30 patients using thoracic epidural analgesia and 30 patients received thoracic para vertebral analgesia for the operation.
Heart rate, mean blood pressure, visual pain score (VAS) ,forced vital capacity(FVC), forced expiratory volume in one second (FEV1) and any side effects , if any were recorded every 2 hours in first 12 hours then every 4 hours in next 12 hours postoperatively . When pain score was ≥4, analgesia was given in the form of i.v. fentanyl in C group and extra dose of local anesthetics solution in the two regional groups .
The study revealed that the analgesia was successfully provided in majority of cases. Pain scores was less in PVB group than the other 2 groups, also FVC and FEV1 were more better in both regional groups. Postoperative analgesic consumption and PONV is less in PVB group when compared to other two groups. Patient satisfaction is comparable in three groups.
The thoracic epidural block and thoracic Para vertebral block provide effective postoperative analgesia following thoracotomy surgery. However in Para vertebral block the complications are much less compared to thoracic epidural block. We recommend that thoracic Para vertebral block is simple and useful method and should be learned and willingly performed by every anesthesiologist.
