This is a randomized, placebo-controlled, double-blinded clinical trial. Patients will be randomized into one of two groups. Group A (Placebo, control group) will receive intrathecal sterile normal saline and Group B (Morphine group) will receive 5mcg/kg preservative free intrathecal morphine.~American Pain Society Outcome Questionnaire (APS-POQ) will be administered to patients prior to discharge (see data sheet).~Patients will be followed up with a phone survey at 1 and 3 months after surgery to assess the presence, nature, and severity of chronic persistent surgical pain. The Brief Pain Inventory is a reliable and valid measures of the interference of pain with physical functioning and will be used. Additionally patients will be asked about use of pain medications
VATS is widely used for diagnosis and treatment of intrathoracic conditions. Despite many benefits, postoperative pain continues to be intense after VATS. The optimal strategy for pain management has not been defined. In this randomized, placebo-controlled, double-blinded clinical investigation, investigators hypothesize that 5 mcg/kg intrathecal morphine will decrease postoperative analgesic consumption and reduce pain.
